Description

The present invention relates to a printed circuit board holder, a use of a printed circuit board holder for locking a printed circuit board, a system comprising a printed circuit board holder and a printed circuit board, and a method for releasing a printed circuit board locked in a printed circuit board holder.

Conventional circuit board mounts are known as hardware of computer systems. Exemplary conventional circuit board mounts are used as sockets for connecting main memory modules for motherboards.

Printed circuit board holders for accommodating printed circuit boards in vehicles are subject to certain requirements that conventional printed circuit board holders, such as those known from computer systems, do not meet.

Printed circuit board holders for accommodating printed circuit boards in vehicles are subject to shocks and vibrations, particularly during vehicle travel, which can lead to damage to printed circuit boards, so that a possible replacement of the printed circuit boards becomes necessary. In addition, the individual vehicle development places different, often conflicting requirements on the hardware that is to be installed in a vehicle.

U.S. 4,712,848 A describes an electrical connector for making electrical connections to a printed circuit board. The connector includes a latch for attaching the printed circuit board to the connector. The connector is mounted on another printed circuit board and makes further electrical connections with it. The latch cooperates with slots located on opposite edges of the printed circuit board and includes a strap member that extends along the rear of the connector housing.

Releasing the latch is relatively easy, without exerting any detrimental forces on the printed circuit boards, by inserting a flathead screwdriver into the opening formed by the yoke member and the back wall of the connector housing and turning the screwdriver in any direction to release the to release the lock.

US 2003/0 186 590 A1 describes a card edge connector comprising a contact terminal group for electrically connecting an electrode group provided at one end of an edge plate to an input-output substrate by selectively pinching the electrode group with a pair of contact portions; a base portion disposed on the input-output substrate to support the contact terminal group and guide-support the outer periphery of the edge plate in an attachable and detachable manner; a gap adjustment wall portion provided between a pair of contact portions in the contact terminal group of the base portion to restrict a gap between the contact portions to a predetermined value; and a locking mechanism, which is arranged in the vicinity of each opposite end of the gap adjustment wall portion in the base portion, for pushing an end of the edge plate, which is pinched by the contact terminal group, in the attachment/detachment direction of the edge plate, around the electrode group of the edge plate into the contact terminal group to move; wherein the locking mechanism comprises hook members rotatably carried by the base portion, having a gap adjustment portion for limiting a gap between the contact portions of the contact terminal group away from the end of the gap adjustment wall portion toward a predetermined value and for pressing an end of the edge plate.

US 2017/0 069 985 A1 describes a unibody socket for receiving a memory module to be connected to a computer system. A section of the unibody socket extends into a latch extension. The latch extension is intended to hold the memory module based on a positive latch holding force that increases in response to an unlatching force of the memory module to prevent removal of the memory module while the latch extension is in a latched position.

DE 27 32 519 A1 describes a spring strip, in particular for the pluggable accommodation of circuit boards, with a strip body accommodating contact springs and essentially U-shaped support strips arranged at the ends thereof, which have guide grooves for the circuit boards with clamping means protruding into them, the support strips being in the side walls of the Guide grooves opposite each other horizontally have two free wall sections, and the wall sections protrude into the guide grooves in an arcuate, resilient manner over partial widths of the guide grooves.

It is therefore the object of the present invention to provide a printed circuit board holder which enables a printed circuit board to be locked in a vibration-proof manner in a printed circuit board holder in a vehicle, makes it easier to replace printed circuit boards and, moreover, meets the requirements of vehicle development.

The object described above is solved by the subject matter of the independent claims, preferred embodiments are the subject matter of the dependent claims.

wobei die Werkzeugöffnung des Werkzeugdurchführelements eine im Wesentlichen axiale Erstreckung entlang einer Werkzeugöffnungsachse aufweist, und die Entriegelungsausnehmung des Werkzeugeinführelements eine im Wesentlichen axiale Erstreckung entlang einer Entriegelungsausnehmungsachse aufweist, und
wobei die Werkzeugöffnungsachse und die Entriegelungsausnehmungsachse parallel sind und in einer Längsrichtung des langgestreckten Aufnahmekörpers zueinander beabstandet sind.One aspect of the invention relates to a printed circuit board holder for receiving a printed circuit board and for fixing the printed circuit board to a base printed circuit board in a vehicle, comprising:

• - an elongate receiving body,
  • -- the elongate receptacle body having a receptacle for locating a contact portion of the circuit board therein; and
• - at least one elastically deformable locking device,
  • -- wherein the at least one elastically deformable locking device has a locking projection configured to engage in a locking recess of the printed circuit board, so that the printed circuit board is locked,
• - wherein the at least one elastically deformable locking device has a tool passage element with a tool opening; and

  • -- wherein the elastically deformable locking device (40) is configured to deform elastically when a tool is guided through the tool opening and into the unlocking recess in such a way that the printed circuit board is unlocked,

wherein the tool opening of the tool passage element has a substantially axial extension along a tool opening axis, and the unlocking recess of the tool insertion element has a substantially axial extension along an unlocking recess axis, and
wherein the tool opening axis and the unlocking recess axis are parallel and spaced from each other in a longitudinal direction of the elongated receiving body.

Advantageously, the printed circuit board holder, which in particular has at least one elastically deformable locking projection configured to engage in a locking recess in the printed circuit board so that the printed circuit board is locked, allows the printed circuit board to be locked in the printed circuit board holder in an elastically releasable manner. In other words, the printed circuit board can be arranged reversibly in the printed circuit board holder and securely fixed and, in particular, replaced in the event of a defect, without the printed circuit board holder having to be plastically deformed for this purpose. Consequently, the present circuit board mount provides a vibration-proof latch for a circuit board while facilitating circuit board replacement.

In exemplary embodiments, the printed circuit board holder can in particular have two elastically deformable locking devices, it being possible for the two elastically deformable locking devices to be arranged opposite one another in the longitudinal direction. As a result, a printed circuit board can be locked in the printed circuit board holder on both sides, as a result of which an advantageously secure and vibration-resistant arrangement or locking of the printed circuit board in the printed circuit board holder is made possible.

In alternate embodiments, the circuit board mount may include any number of resiliently deformable locking devices.

The at least one elastically deformable locking device can be arranged in particular in an end region of the elongated receiving body or in an end region of the receptacle.

In the further course, various terms are used repeatedly, the understanding of which is to be made easier by the following definitions.

Elongated: In the present case, the term elongate is mostly used with the term receiving body and indicates that the element referred to therein, in particular the receiving body, has an extent in the longitudinal direction which is significantly greater than its extent in the width and/or height direction. With respect to the elongate containment body, it may have a length of about 20 to about 60 times a width of the elongate containment body or a length of about 5 to about 40 times a height of the elongate recording body.

Longitudinal direction: The longitudinal direction describes a direction in which the printed circuit board holder or the elongated receiving body has its longest extension. Furthermore, the longitudinal direction is substantially parallel to a long edge of a contact portion of a printed circuit board that can be placed in the receptacle of the elongate receptacle body, such as in a main memory module.

Height direction: The height direction is generally perpendicular to the longitudinal direction and essentially corresponds to a normal to a base circuit board, in particular a normal to a base circuit board extending over a surface area. Furthermore, the height direction can essentially correspond to a direction in which the printed circuit board is pushed or plugged into the receptacle of the elongated receptacle body.

Width direction: The width direction is generally substantially perpendicular to the length direction and the height direction. In the present application, the width direction is essentially used to describe wall thicknesses, wall thicknesses or the like. The width direction may further correspond to an edge of a contact portion of a circuit board that extends along the short side.

The longitudinal direction, the height direction and the width direction in particular do not have to correspond to a longitudinal direction, a height direction and a width direction of a vehicle, but rather can be independent of them.

The height direction, the width direction and the longitudinal direction can form a coordinate system, in particular a legal system.

Vibration-resistant: The term vibration-resistant is mostly used here to characterize a connection, attachment or fixation. Vibration-resistant describes the fact that a connection, connection or fixation does not come loose by itself in the event of vibrations and shocks in the spectrum that is typical for the application and in a certain range.

Vibration-stable: The term vibration-stable is mostly used here to characterize an element or component itself. Vibration-stable describes the fact that an element or component does not oscillate or vibrate on its own in the event of vibrations and shocks in the application-typical spectrum and in a certain range beyond that.

Non-destructively detachable: A non-destructively detachable connection is a connection between two elements or components whose detachment causes the partial or complete destruction of at least one of the two elements or components that are detached from one another. The connection of two elements cannot be detached without being destroyed, even if the use of solvents to separate the two elements from one another causes at least the negative impairment of the material properties or structure of at least one of the two elements. Examples of non-destructively detachable connections are adhesive connections, for example using adhesives, material-to-material connections that are created, for example, by welding processes, mechanical connections that are created, for example, by riveting two or more elements, and other connections that do not have the associated property of the meet non-destructive detachability.

Base circuit board: Base circuit board means a printed circuit board or PCB (printed circuit board) that serves as the basis for connection or fixation. The base circuit board can be any circuit board. Alternatively, the base circuit board can also describe a base module, which is used, among other things, for connecting or fixing further circuit boards.

Elastically deformable/elastic deformation: Elastic deformability describes that an element or component can be elastically deformed, in other words it can be deformed in particular in such a way that the element or component after the deformation essentially completely or completely regains its geometry has before deformation. An elastic deformation is limited in that it describes a deformation in which essentially no or no plastic deformation occurs. An elastically deformed element can be essentially completely restored to an initial state.

According to the first aspect, the at least one elastically deformable locking device has a tool feed-through element with a tool opening, and the printed circuit board holder has a tool insertion element with an unlocking recess, the unlocking recess being arranged at a distance from the tool opening in the height direction, and the elastically deformable locking device being configured to by guiding a tool through the tool opening and into the unlocking recess to be elastically deformed in such a way that the circuit board is unlocked, in other words that the locking projection no longer engages in the locking recess of the circuit board.

The unlocking recess, which is arranged at a distance from the tool opening in the vertical direction, can in particular be arranged at a distance from the tool opening in the vertical direction of the elongated receiving body or the circuit board holder. The unlocking recess can, for example, be arranged below the tool opening in the height direction.

A circuit board holder can advantageously be provided by a tool feed-through element with a tool opening and a tool insertion element with an unlocking recess, which enables a particularly user-friendly unlocking of a circuit board in the circuit board holder. A possibly necessary replacement of a printed circuit board can thus be simplified by only requiring a tool which is suitable for being guided through a tool opening and inserted into a tool opening. A screwdriver, a pen, or alternatively another special tool or general tool can serve as a tool, for example.

In addition, the process, which is essentially defined by means of a tool feed-through element and tool insertion element or by means of a tool opening and unlocking recess and which leads to the elastically deformable locking device being elastically deformed, can advantageously be carried out automatically, for example by a robot. In this way, for example, when a circuit board holder is being equipped with a circuit board, a tool can be guided through the tool opening and into the unlocking recess by means of a robot arm, so that the elastically deformable locking device deforms elastically, after which, for example, another robot arm arranges a circuit board in the circuit board holder can do. Furthermore, for example, when replacing a printed circuit board or simply removing a printed circuit board from a printed circuit board holder, a tool can be guided through the tool opening and into the unlocking recess by means of a robot arm, so that the elastically deformable locking device deforms elastically and the locking projection from the locking recess of the printed circuit board moves, after which, for example, another robot arm can remove and, if necessary, insert a different or new circuit board into the circuit board holder. Thus, based on the present circuit board holder by means of the arrangement of a tool feed-through element with a tool opening and a tool insertion element with an unlocking recess, automated assembly, replacement and removal of circuit boards in or from a circuit board holder can advantageously be made possible.

The tool opening can extend in particular with a continuous opening or a through hole along a tool opening axis of the tool feedthrough element. Furthermore, the axis of the tool opening can in particular be parallel to the vertical direction of the elongated receiving body or the printed circuit board holder, but can also deviate from it.

Furthermore, in exemplary embodiments, the tool opening can in particular extend cylindrically along the axis of the tool opening. In alternative embodiments, the tool opening can be configured as a polygon in cross section, in particular as a triangle, square, pentagon or hexagon. The diameter or cross section of the tool opening can have a ratio in particular in the range from about 1.01 to about 1.3 to the diameter or cross section of a tool that is passed through.

The unlocking recess can be configured in particular as a blind hole along an unlocking recess axis. In other words, the unlocking recess cannot be configured as a continuous opening, but rather have a unlocking recess base. An unlocking recess base can advantageously protect a base circuit board from being damaged by a tool during an unlocking process.

Alternatively, the unlocking recess can be configured in particular as a through hole. An unlocking cutout, which is configured as a through hole, advantageously enables the unlocking cutout to be configured as an additional means for fixing the circuit board holder to a base circuit board.

Furthermore, the axis of the unlocking recess can in particular be parallel to the vertical direction of the elongated receiving body or the printed circuit board holder. However, the unlocking recess axis can also deviate from the height direction of the elongated receiving body.

Furthermore, in exemplary embodiments, the unlocking recess can in particular extend cylindrically along the unlocking recess axis. In alternative embodiments, the unlocking recess can be configured in cross-section as a polygon, in particular as a triangle, square, pentagon or hexagon.

The diameter or cross section of the unlocking recess can have a ratio in the range of approximately 1.01 to approximately 1.3 to the diameter or cross section of the inserted tool. The ratio of the diameter or cross-section of the unlocking recess to the diameter or cross-section of the inserted tool influences the necessary extent of the tool insertion element in the height direction, since when the tool is inserted, depending on the diameter or cross-section ratio, the tool forces a different force as it is inserted into the unlocking recess Learns inclination relative to the Entriegelungsausnehmungsachse.

On the one hand, a large diameter or cross-section ratio of the unlocking recess to the tool has the advantageous effect that the tool can be inserted easily, so that detachment of the printed circuit board from the printed circuit board holder is made easier as a result.

On the other hand, a small diameter or cross-section ratio of the unlocking recess to the tool has the advantageous effect that the tool is inclined towards the unlocking recess axis over an already small height of the tool insertion element and elastic deformation can be applied to the elastically deformable locking device, so that a less material is required, and the production is thus simplified and cheaper.

According to the first aspect of the circuit board holder, the tool opening of the tool feed-through element has a substantially axial extension along a tool opening axis and the unlocking recess of the tool insertion element has a substantially axial extension along an unlocking recess axis, the tool opening axis being different from the unlocking recess axis.

Advantageously, the tool opening, which extends essentially axially along a tool opening axis, and the unlocking recess, which extends essentially axially along an unlocking recess axis, with the tool opening axis being different from the unlocking recess axis, enable elastic deformation of the elastically deformable locking device is ensured when passing a tool through the tool opening and then inserting the tool into the unlocking recess of the elastically deformable locking device.

According to the first aspect, the tool opening axis and the unlocking recess axis are parallel to each other. In alternate examples, they may be configured skew to each other, or may intersect at some point. If the tool opening axis and the unlocking recess axis are configured so that they intersect at a certain point, the point is preferably chosen such that it is configured in the height direction below the upper edge in the height direction of the unlocking recess in order to ensure elastic deformation of the elastically deformable locking device . The elastic deformation of the elastically deformable locking device advantageously causes the locking projection to be moved in a direction away from the receptacle or a direction away from the locking recess of the printed circuit board, so that the printed circuit board is unlocked due to the elastic deformation of the elastically deformable locking device.

According to the first aspect of the board holder, the tool opening axis and the unlocking recess axis are configured parallel to each other. Furthermore, according to the first aspect, the unlocking recess axis and the tool opening axis are spaced apart from one another at least in the longitudinal direction of the elongated receiving body.

In other words, in a locking state of the circuit board holder, a circuit board can be arranged or fixed in the receptacle, with the locking projection of the elastically deformable locking device engaging in a locking recess in the circuit board. Furthermore, in a locking state of the board holder, the tool opening axis and the unlocking recess axis can be configured parallel to each other. A locking state of the circuit board holder can be characterized in particular in that the elastically deformable locking device is in a basic state, with the elastically deformable locking device having no elastic deformation or deflection.

For example, the tool opening axis and the unlocking recess axis can be substantially parallel to the height direction of the elongated receiving body.

Furthermore, by way of example, the tool opening axis and the unlocking recess axis can be configured spaced apart from one another in the longitudinal direction of the elongated receiving body. In particular, the unlocking recess axis can be spaced apart from the tool opening axis in the longitudinal direction, away from the receptacle of the elongated receptacle body.

For example, if the tool opening axis is parallel to the unlocking recess axis and the two axes are longitudinally spaced from each other, unlocking movement of the locking projection from the locking recess of the printed circuit board can be ensured by inserting a tool through the tool opening and into the unlocking recess. In particular, the printed circuit board holder can be brought from a locked state into an unlocked state, the elastically deformable locking device being elastically deformed in an unlocked state of the printed circuit board holder in such a way that the locking projection does not engage in the locking recess of the printed circuit board. In other words, the unlocked state of the circuit board holder can be characterized in that the elastically deformable locking device is in a deflection state, the elastically deformable locking device being elastically deformed or deflected in such a way that the locking projection does not engage in the locking recess of the circuit board. In other words, the unlocked state of the printed circuit board holder can be characterized in that a printed circuit board can be guided or removed from the receptacle of the printed circuit board holder, the locking projection not impairing the guidance or removal of the printed circuit board from the receptacle. Likewise, an unlocked state of the circuit board holder can be characterized in that the elastically deformable locking device is elastically deformed in such a way that a circuit board can be inserted into the receptacle of the circuit board holder, with the locking projection not impairing the insertion.

Because the tool opening axis is parallel to the unlocking recess axis, for example, and the two axes are spaced apart from one another in the longitudinal direction, a targeted transition of the elastically deformable locking device from a basic state to a deflection state can advantageously be ensured. The ensured targeted transition from a basic state to a deflection state of the elastically deformable locking device by guiding a tool through the tool opening and into the unlocking recess advantageously enables an unlocking movement of the locking projection out of the locking recess of the printed circuit board.

In preferred embodiments of the circuit board holder, the tool insertion element can be configured more rigidly than the tool feedthrough element.

In other words, the tool insertion element can be stiffer than the tool feedthrough element with respect to a deflection in the longitudinal direction facing away from the receptacle of the elongated receptacle body. In particular, the tool insertion element can be stiffer than a deformation section of the elastically deformable locking device with respect to a deflection in the longitudinal direction facing away from the receptacle of the elongated receiving body. A deformation section of the elastically deformable locking device can in particular be provided with a comparatively thin wall thickness measured in the longitudinal direction and in particular lie below a section on which the locking projection and the tool passage element are arranged.

For example, the tool insertion element and the tool passage element can be comparatively stiff compared to a deformation section of the elastically deformable locking device, with the deformation section being configured to essentially elastically deform when a tool is guided through the tool opening and into the relief recess, in particular elastically deforming more easily than the tool insertion element and the tool passage element. In other words, the tool insertion element and the tool feedthrough element can be comparatively stiffer than a deformation section of the elastically deformable locking device. The deformation section can be arranged, for example, in an area of the elastically deformable locking device that lies in the vertical direction between the elongated receiving body and the tool insertion element or locking projection. Furthermore, by way of example, the deformation section can be arranged in a region of the elastically deformable locking device which lies in the vertical direction between a fixing section of the printed circuit board holder and the tool insertion element or locking projection. The comparatively stiffer configuration of the tool insertion element and the tool feedthrough element can relate in particular to a deflection in the longitudinal direction away from the receptacle. In other words, the comparatively stiffer configuration of the tool insertion element and the tool feed-through element can relate in particular to a bending in the longitudinal direction away from the receptacle with a bending axis which runs essentially along the width direction. The deformation section can in particular have a wall thickness, measured in the deflection direction, which is thin in sections.

Because the tool insertion element is configured to be comparatively stiffer, it is ensured that the elastically deformable locking device is elastically deformed, while the tool insertion element remains undeformed or is only subject to minor deformations, in particular elastic deformations.

The tool insertion element can be reinforced, for example, by increasing the wall thickness.

In other exemplary embodiments, the tool insertion element can have a plurality of stiffening elements. By arranging stiffening elements on the tool insertion element in order to stiffen it, the tool insertion element and thus the printed circuit board holder can also be configured particularly suitable for injection molding by avoiding accumulations of material, so that in turn a possible distortion can be reduced or avoided.

In preferred embodiments of the circuit board holder, the tool opening and/or the unlocking recess can be formed with a substantially cylindrical inner wall.

A cylindrically shaped inner wall of the tool opening and/or the unlocking recess advantageously makes it possible for both round and polygonal tools to be used in order to be guided through the tool opening and into the unlocking recess.

In other exemplary embodiments, the tool opening and/or the unlocking recess can be shaped with a polygonal inner wall, so that an unlocking code for a special tool or special tool is provided, which prevents or at least makes it more difficult for non-specialist personnel to release or unlock the circuit board from the circuit board holder .

According to the first aspect of the circuit board holder, the tool opening axis and the unlocking recess axis are parallel to each other and spaced apart from each other in the longitudinal direction of the elongate receiving body.

In exemplary embodiments, the tool opening axis and the unlocking recess axis can be parallel to one another and provided with an unlocking distance in the longitudinal direction to one another which is approximately 1.1 to approximately 5.0 times, preferably approximately 2.5 times the extent in the longitudinal direction of the locking projection in the Locking recess corresponds.

This ensures that when the tool is passed through the tool opening and then inserted into the unlocking recess, a sufficiently large elastic deformation is applied to the elastically deformable locking device, so that unlocking of the printed circuit board in the printed circuit board holder is ensured. In other words, a transition of the elastically deformable locking device from the locking state to an unlocking state is advantageously ensured on the basis of the exemplary spacing of the tool opening axis from the unlocking recess axis. In particular, spacings in the longitudinal direction of the parallel tool opening axis and unlocking recess axis which are in relation to the extension of the locking projection in the locking recess above about 2.0 allow that a tool can be used with a tool diameter which is thin compared to a cross-sectional diameter of the tool opening. Furthermore, an aspect ratio above about 2.0 allows the tool to be inserted only slightly into the unlocking recess in order to elastically deform the elastically deformable locking device such that unlocking of the circuit board in the circuit board holder occurs.

In preferred embodiments of the circuit board holder, the tool insertion element can have a plurality of stiffening elements.

By arranging a plurality of stiffening elements on the tool insertion element, the tool insertion element is stiffened so that when a tool is passed through the tool opening and then inserted into the unlocking recess, the elastically deformable locking device elastically deforms more easily than the tool insertion element. In particular, stiffening elements on the tool insertion element allow the elastically deformable locking device to be elastically deformed and the tool insertion element to be essentially not deformed when a tool is passed through the tool opening and then inserted into the unlocking recess. Stiffening elements, which are arranged on the tool insertion element, thus advantageously make it possible for the tool insertion element to essentially retain or completely retain its geometry over a number of unlocking processes.

In exemplary embodiments, a plurality of stiffening elements can be arranged on the tool insertion element, with the stiffening elements extending essentially in the height direction.

Because the stiffening elements of the plurality of stiffening elements extend essentially in the vertical direction, the tool insertion element can advantageously be stiffened against elastic deformation or deflection in the longitudinal direction. In particular, a plurality of stiffening elements, which extend essentially in the height direction, makes it possible for the tool insertion element not to be tilted or pivoted during an unlocking process or over a number of unlocking processes.

In exemplary embodiments, the tool insertion element can have, in particular, four stiffening elements. In alternative embodiments, the tool insertion element can have any number of stiffening elements, such as one, two, three, four, five, six, seven or eight stiffening elements.

In preferred embodiments of the printed circuit board holder, the elongated receiving body can have a first end and a second end in the longitudinal direction, and the printed circuit board holder can have a first fixing section which is arranged at the first end of the elongated holding body and a second fixing section which is arranged at the second end of the elongated receiving body is arranged, wherein at least a first fixing element can be fixed on the first fixing section in order to be fixed on the base circuit board, and at least a second fixing element can be fixed on the second fixing section in order to be fixed on the base circuit board, wherein the at least a tool insertion element can be arranged on at least one of the first fixing section and the second fixing section, and wherein the unlocking recess of the at least one work zeugeinführungselements is arranged in the longitudinal direction, facing away from the receptacle spaced from the tool opening.

The first end and second end of the elongated receiving body in the longitudinal direction each represents a transition region between the elongated receiving body and the respective first and second fixing section. In other words, the first end and second end in the longitudinal direction of the elongated receiving body is an end region and not a geometrically defined location .

By arranging the at least one tool insertion element on at least one of the first fixing section and the second fixing section, with the first and second fixing section each being configured to be fixed on the base circuit board by at least one fixing element, the tool insertion element can be stabilized so that a stable or trouble-free unlocking process is made possible.

Furthermore, during an unlocking process of the circuit board, with a tool being inserted into the unlocking recess of the tool insertion element, a force can be applied from the tool via the tool insertion element directly to the fixing section, the fixing element fixed thereto and finally to the base circuit board. As a result, during an unlocking process, the force is advantageously dissipated via the base circuit board, in particular without running through the elongated receiving body, so that the possibility of damage to the circuit board is reduced.

In addition, the unlocking recess of the tool insertion element, which is arranged in the longitudinal direction away from the receptacle of the printed circuit board at a distance from the tool opening, enables a tool to be levered when it is passed through the tool opening and then inserted into the unlocking recess, with the center of rotation in the area of the unlocking recess and the direction of rotation in the longitudinal direction turned away from the recording. As a result, during the levering process, a tool handle is moved in the vertical direction away from the receptacle, so that removal of a loosened or unlocked printed circuit board is facilitated in the vertical direction.

In exemplary embodiments, the circuit board holder can have exactly two tool insertion elements and exactly two elastically deformable locking devices. For example, a tool insertion element can be arranged on the first fixing section and a further tool insertion element can be arranged on the second fixing section, so that exactly two tool insertion elements can be arranged opposite one another in the longitudinal direction. By way of example, one elastically deformable locking device can also be arranged in a region of the first end of the elongate receiving body and the other elastically deformable locking device can be arranged in a region of the second end of the elongate receiving body.

In alternative embodiments, the circuit board holder can have any number of tool insertion elements and further have any number of elastically deformable locking devices.

In preferred embodiments of the circuit board holder, the locking projection can be configured flat on its underside.

Advantageously, a locking projection that is configured or formed with a flat underside makes it difficult or prevents independent movement or deflection of the printed circuit board in the vertical direction and out of the locked state. This is made possible by the fact that the flat configured underside of the locking projection makes it more difficult or prevents the locking recess from sliding off the locking projection in the height direction from bottom to top.

In exemplary embodiments, the bottom of the locking protrusion may be configured to extend in a plane configured substantially parallel to the longitudinal and width directions.

In further exemplary embodiments, the underside of the locking projection may have a decreasing height along the extension into a locking recess of a printed circuit board such that the locking projection is configured as an engaging tooth inclined downward in the height direction.

In further exemplary embodiments, the locking protrusion can be configured with any shape and/or slope. In exemplary embodiments, a section of the locking projection facing the locking recess of the printed circuit board can comprise or be provided with a material that has a high coefficient of friction, such as an elastomer.

In other words, the positioning projections can be configured to extend from the respective positioning element towards a side surface of a circuit board arranged in the receptacle. In particular, the essential extent of the positioning projections can be rotated by approximately 90° in relation to the essential extent of the locking projection. For example, the positioning projections can extend from the respective positioning elements essentially in the width direction towards the printed circuit board and the locking projection can extend essentially in the longitudinal direction towards the printed circuit board, in particular in a locking recess of the printed circuit board.

A positioning gap configured between the positioning projections in the width direction can be smaller than a thickness of a printed circuit board in the width direction, correspond precisely to a thickness of a printed circuit board in the width direction, or be greater than a thickness of a printed circuit board in the width direction.

By configuring the positioning gap between the positioning projections in the width direction of the elongated receiving body, the printed circuit board can advantageously be clamped, supported or limited in displacement in the width direction.

The printed circuit board can be advantageously guided during a removal process, without additionally restricting a movement of the printed circuit board in the vertical direction, by means of an underside of a positioning projection which is inclined upwards towards the printed circuit board.

In alternative embodiments, the locating protrusions may have concave portions, which may face the circuit board and may be configured to clamp the circuit board widthwise, to guide it, or to limit the deflection of the circuit board.

1 shows a circuit board holder 10. Here are in 1 three spatial directions defined, namely the longitudinal direction I, the height direction b and the width direction b, which have no fixed origin on the circuit board holder 10. The longitudinal direction I runs essentially parallel to an elongated extension of an elongated receiving body 20 of the circuit board holder 10. The height direction h runs essentially perpendicular to the longitudinal direction I and is also essentially perpendicular to a base circuit board 150 on which the circuit board holder 10 is configured fixed to become. The width direction b runs essentially perpendicular to the longitudinal direction I and to the vertical direction b, so that in particular a right-handed directional system consists of the longitudinal direction I, vertical direction h and width direction b.

As in 1 As shown, the elongate receiving body 20 has a receptacle 24 which opens upward in the height direction and is configured to place a contact portion 110 of a printed circuit board 100 therein. Furthermore, the elongate receiving body 20 can optionally have a coding 23 which is arranged in the receptacle 24 of the elongate receiving body. The coding 23 can be configured to engage in a coding recess 130 of a circuit board 100 when the circuit board 100 is arranged in the recess 24 . The circuit board holder 10 can be designed or restricted to accommodate a specific type of circuit board 100 based on the coding 23 of the elongated receiving body 20 .

In alternative embodiments of the printed circuit board holder 10, the elongate receiving body 20 has no coding 23.

As in 1 shown, the elongate receiving body 20 has a first end 21 and a second end 22 in the longitudinal direction I, the first end 21 and the second end 22 in the longitudinal direction I im substantially opposite. The first end 21 is or includes a transition area, in particular a transition area in the longitudinal direction I at the front, between the elongated receiving body 20 and the first fixing section 31 which is arranged on the elongated receiving body 20 . The second end 22 is or includes a transition region, in particular a transition region in the longitudinal direction I at the rear, between the elongated receiving body 20 and the second fixing section 32 which is arranged on the elongated receiving body 20 . The first end 21 and the second end 22 of the elongate receiving body 20 are therefore to be understood as a transition region rather than as a fixed geometric location, in particular if the elongate receiving body 20 is formed integrally or in one piece with the first fixing section 31 and the second fixing section 32 , In particular is made.

In exemplary embodiments, the elongate receiving body 20 can be manufactured integrally or in one piece with the first fixing section 31 and the second fixing section 32 in an injection molding process, as a result of which the elongate receiving body 20, the first fixing section 31 and the second fixing section 32 have or are made of the same material consist, in particular, have or consist of a plastic such as PA, PP, PE, EP resins, PMMA, PEEK or PUR, or optionally in particular a fiber-reinforced plastics such as PA, PP, PE, EP resins, PMMA, PEEK, PUR with a glass fiber content in the range of 5% to 40% or consist of such as PA6GF30, PA66GF30, PA6GF15 or PA66GF15. In particular, the production of the circuit board holder 10 or the elongated receiving body 20, the first fixing section 31 and the second fixing section 32 from fiber-reinforced plastic makes it possible to increase the vibration resistance or stability of the circuit board holder 10 in a targeted manner and to increase the thermal conductivity in a targeted manner in order to To improve heat transport or -Abtransport between circuit board 100 and base circuit board 150.

In further exemplary embodiments, the elongated receiving body 20 can be manufactured integrally or in one piece with the first fixing section 31 and the second fixing section 32 in a multi-component injection molding process, whereby the elongated receiving body 20, the first fixing section 31 and the second fixing section 32 have different plastics or fiber-reinforced plastics can or can consist of them, whereby targeted material properties can be provided for the circuit board holder 10 .

In alternative embodiments, the elongated receiving body 20, the first fixing section 31 and the second fixing section 32 can be manufactured separately from one another, i.e. in several pieces, and then connected to one another, such as by gluing, welding, screwing or any other method.

The elongate receiving body 20, the first fixing section 31 and the second fixing section 32 can have a length in the longitudinal direction together, for example, in the range from about 80 mm to about 240 mm, preferably a length in the range from about 120 mm to about 180 mm, and particularly preferably have a length of about 165 mm. The elongated receiving body 20, the first fixing section 31 and the second fixing section 32 can each have a width in the range from about 2.8 mm to about 8 mm, preferably a width in the range from about 3.4 mm to about 6 mm, and particularly preferably have a width of about 4.5 mm. In alternative embodiments, the printed circuit board holder 10, in particular the elongate receiving body 20 and the first and second fixing sections 31, 32 adjoining it in the longitudinal direction, can have dimensions which are tailored in particular to the printed circuit board 100 to be arranged in the printed circuit board holder 10 and depend on the above-mentioned values or value ranges differ.

Furthermore shows 1 two pairs of positioning elements 50, the pairs of positioning elements 50 being arranged opposite one another in the longitudinal direction I, in each case on the elongate receiving body 20. For example, the pairs of positioning elements 50 can adjoin the receptacle 24 of the elongated receptacle body 20 in the longitudinal direction I at the front and rear. Furthermore, the pairs of positioning elements 50, as in 1 shown, in the height direction h in relation to the receptacle 24 protrude or stand, ie stretch up or stand.

The positioning elements 52 of the pairs of positioning elements 50 can in particular protrude or extend essentially with a U-profile along the vertical direction h in relation to the receptacle 24 . The U-profile of the positioning elements 52 enables a vibration-resistant and rigid design of the positioning elements 52, and at the same time a design that is particularly suitable for injection molding tion, since material accumulations of injection molded material are avoided, which in turn can reduce or avoid possible warping.

Furthermore shows 1 that the circuit board holder 10 has two elastically deformable locking devices 40, which are arranged adjacent to the first end 21 and second end 22 of the elongated receiving body 20. The elastically deformable locking device 40 extends essentially in the height direction h and is also arranged in the longitudinal direction I at a distance from the pair of positioning elements 50, in particular in the longitudinal direction I, facing away from the receptacle 24, at a distance from the pair of positioning elements 50 arranged. In particular, the elastically deformable locking device 40 is spaced apart from the pair of positioning elements 50 by a gap in the longitudinal direction I in order to ensure elastic deformability of the elastically deformable locking device 40 . Furthermore, the wall thickness of the elastically deformable locking device 40, which runs essentially in the height direction h, decreases with increasing height in the longitudinal direction I in order to increase the elastic deformability of the elastically deformable locking device 40 in the longitudinal direction I as the height of the elastically deformable locking device 40 increases. In other words, a wall thickness of the elastically deformable locking device 40 that decreases with increasing height advantageously enables the rigidity of the elastically deformable locking device 40 to be reduced in a targeted manner in order to provide a targeted elastic deformability of the elastically deformable locking device 40 .

As in 1 shown, the elastically deformable locking device 40 has a tool passage element 42 which is provided with a tool passage opening 44 . The tool passage element 42 can in particular be arranged at an upper end of the elastically deformable locking device 40 in the vertical direction h. Furthermore, the tool passage element 42 can be arranged on the elastically deformable locking device 40 , in particular in the longitudinal direction I, facing away from the receptacle 24 .

As in 1 Also shown, the circuit board holder 10 has two tool insertion elements 70 which are each provided with an unlocking recess 72 . As in 1 As illustrated, the tool insertion element 70 has a spacing in the height direction h and a spacing in the longitudinal direction I from the tool passage element 42 . In particular, tool insertion element 70 or unlocking recess 72 of tool insertion element 70 is spaced apart from tool feedthrough element 42 or tool opening 44 in longitudinal direction I, away from receptacle 24, and is arranged below tool feedthrough element 42 or tool opening 44 in height direction h.

As in 1 indicated and further through 3a clarified, the elastically deformable locking device 40 is configured to deform elastically when a tool is guided through the tool opening 44 and into the unlocking recess 72 in such a way, in particular to deform with a bend essentially in the longitudinal direction I, that the printed circuit board 100 is unlocked. by a locking projection 46, which is arranged on the elastically deformable locking device 40, is moved out of a locking recess 120 of the printed circuit board 100.

As in 1 shown further, two first fixing elements 61, 61′ are fixed or arranged on the first fixing section 31, which extend with a region essentially in the width direction b, in particular perpendicular to an outside in the width direction b of the first fixing section 31. The fixing elements 61, 61', 62, 62', as partially shown in 1 1 are configured to be fixed to the base circuit board 150. FIG. By fixing the fixing members 61, 61', 62, 62' to the first and second fixing portions 31, 32, respectively, and configuring them to be fixed to the base circuit board 150, the circuit board holder 10 can be fixed to the base circuit board 150 in a vibration-resistant and stable manner or be attached.

2 shows a circuit board holder 10 in an oblique view and a circuit board 100 not accommodated by the circuit board holder 10 in a front view.

The printed circuit board 100 has a contact section 110 in the lower region in the height direction h, which is configured to be received by the receptacle 24 or to be arranged therein. In addition, the circuit board 100 can have a coding cutout 130 as an interruption of the contact section 110 . Depending on the printed circuit board 100 , the coding recess 130 can be arranged in a different length region of the contact section 120 . The coding recess 130 is in particular dere configured to engage with a coding 23 of the elongated receiving body 20 when arranging the contact portion 110 in the receptacle 24, whereby an assembly of unsuitable or unwanted circuit boards 100 in the circuit board holder 100 can be avoided.

In preferred embodiments, circuit board 100 is part of a DDR5 main memory module. However, in further exemplary embodiments, the circuit board can also be any other main memory module, or any other circuit board.

3a shows a portion of a printed circuit board holder 10 in an oblique view. First clarified 3a the extension of the positioning elements 52 of the pair of positioning elements 50 in the height direction h with a U-profile beyond the receptacle 24.

Furthermore shows 3a that the tool opening 44 of the tool passage element 42 is preferably configured round or cylindrical and extends along a tool opening axis 45. Furthermore, the tool opening 44 is preferably provided with a tool opening chamfer, which enables automatic centering when inserting or guiding a tool (not shown) through the tool opening 44 or simplifies inserting a tool into the tool opening 44 . The outer edge of the tool opening chamfer preferably has a diameter which is in the range from about 1.05 to about 1.5, more preferably in the range from about 1.15 to 1.35, in relation to a diameter of the tool opening 44, whereby the Introducing a tool into the tool opening 44 can advantageously be facilitated.

The tool opening 44 is always configured as a through hole to ensure possible passage of a tool. The tool opening 44 is preferably configured with a diameter that is 1.05 to 1.3 times a cross-sectional dimension of a tool. In particular, the tool opening 44 can have a cross-sectional diameter of approximately 1.5 mm to approximately 3.5 mm.

In alternative embodiments, the tool opening 44 may be configured other than a cylindrical shape, particularly configured with a polygonal shape extending along the tool opening axis 45, such as a triangular, square, pentagonal, or hexagonal shape.

Furthermore shows 3a that the unlocking recess 72 of the tool insertion element 70 is preferably configured round or cylindrical and extends along an unlocking recess axis 73 . The unlocking recess 72 can be configured as a through hole with a constant diameter, or configured as a blind hole with a constant diameter, or in particular configured as a through hole with a sectionally constant diameter. An unlocking recess 72, which is configured as a blind hole with a constant diameter, allows damage to the base circuit board 150 to be advantageously avoided when inserting a tool into the unlocking recess 72, since the inserted tool does not reach the base circuit board 150. In contrast, an unlocking recess 72, which is configured as a through hole with a constant diameter in sections, allows a fastening element, such as a screw, for example, to additionally be inserted via the unlocking recess 72 for additional fastening of the circuit board holder 10 to a base circuit board 150. The unlocking recess 72 can, for example, have a cross-sectional diameter in the range from approximately 1.5 mm to approximately 3.5 mm, preferably in the range from approximately 1.7 mm to 2.5 mm. The unlocking recess 72 can also, for example, have a smaller cross-sectional diameter than the tool opening 44. This can ensure that the tool opening 44 allows a tool to be easily passed through, while the unlocking recess 72 ensures that the tool tilts while the tool is inserted into the unlocking recess 72, for example along the height direction h or along the axis 73 of the unlocking recess.

As also in 3a As shown, the tool opening axis 45 and the unlocking recess axis 73 are different from each other. As a result, when a tool is passed through the tool opening 44 and the tool is then inserted into the unlocking recess 72, the elastically deformable locking device 40 can move the tool insertion element 42, which is arranged on the elastically deformable locking device 40, with the tool opening axis 45 towards the unlocking recess axis 73 or move. The tool opening axis 45 is preferably spaced apart from the unlocking recess axis 73 in the longitudinal direction I of the elongated receiving body 20, so that when a tool is passed through the tool opening 44 and the insertion of a tool into the unlocking recess 72, the elastically deformable locking device 40 is elastically deformed in the longitudinal direction I, away from the recess 24.

In further exemplary embodiments, the tool opening axis 45 and the unlocking recess axis 73 may be configured parallel to one another, skewed to one another, or intersecting at a certain point. If the tool opening axis 45 and the unlocking recess axis 73 are configured to intersect at a certain point, the point should preferably be selected such that it is configured in the height direction below the upper edge of the unlocking recess 72 in order to avoid elastic deformation of the elastically deformable Locking device 40 ensure. This elastic deformation leads to a locking projection 46 being moved out of the locking recess 120 of the printed circuit board 100 .

Furthermore shows 3a that the tool insertion element 70 can be provided with a plurality of stiffening elements 71 on its outside, which essentially extend in the height direction h. A plurality of stiffening elements 71, which are arranged on tool insertion element 70, make tool insertion element 70 particularly stiff with respect to deformation in longitudinal direction I, so that when a tool is inserted into tool insertion element 70, it is ensured that essentially elastically deformable locking device 40 is elastic deformed, while the tool insertion element 70 remains undeformed or is only slightly deformed.

The stiffening elements 71 can be arranged or designed, for example, in the form of ribs on the outside of the tool insertion element 70 .

Furthermore shows 3a as an example for the fixing elements 61, 61′, 62, 62′ a configuration in certain areas, in particular based on the first fixing element 61, which has a fastening area 63, a fixing area 65 and a contour area 67. To differentiate between the areas of the first fixing element 61, 61' and those of the second fixing element 62, 62', the terms first fixing area 63, 63' for the first fixing element 61, 61' are also used for the fixing area 63, 63', 64, 64. and second attachment area 64, 64' for the second fixing element 62, 62', for the attachment area 65, 65', 66, 66' the terms first attachment area 65, 65' for the first attachment element 61, 61' and second attachment area 64 are also used , 64' for the second fixing element 62, 62', as well as for the contour area 67, 67', 68, 68' also the terms first contour area 67, 67' for the first fixing element 61, 61' and second contour area 68, 68' used for the second fixing element 62, 62'.

The first fastening area 63 of the first fixing element 61 extends essentially in the width direction b and protrudes from the first fixing section 31 or the elongated receiving body 20 in the width direction b. Furthermore, the fastening area 63 of the first fixing element 61 preferably extends along an underside of the circuit board holder 10 in order to be fixed to a base circuit board 150 when the circuit board holder 10 is fixed.

In alternative embodiments, the first fastening area 63 of the first fixing element 61 can extend deviated from a width direction and along a lower side of the circuit board holder 10 as long as the first fastening area 63 is further configured to be fixed to a base circuit board 150 .

The first fixing portion 65 of the first fixing member 61 is configured to fit in a first fixing recess 35 as shown in FIGS 3b , 5a and 5b shown to be fixed. The first fixing area 65 of the first fixing element 61 extends essentially in the height direction h with a contoured shape in the longitudinal direction I. The first fixing area 65 of the first fixing element 61 connects in particular to the first fixing area 63 of the first fixing element 61 and extends with others Words essentially perpendicular to the first fastening area 63 of the first fixing element 61.

The first contour area 67 of the first fixing element 61 preferably has a contour which in sections along a first connection opening 37, as in FIGS 3b , 5a and 5b shown, runs. The first contour area 67 of the first fixing element 61 can in particular extend along and adjacent to an upper side of the first fixing section 31 . Optionally, the first contour area 67 of the first fixing element 61 can extend in particular along and in contact with the upper side of the first fixing section 31 . Due to the fact that the first contour area 67 extends in sections along the contour of the first connection opening 37, the first contour area 67 can be in contact with be brought to a connection element. The first contour area 67 connects in particular to the first fixing area 65 of the first fixing element 61 and, in other words, extends essentially perpendicularly to the first fixing area 65 of the first fixing element 61.

In exemplary embodiments, a cooling element 14, as in 10 shown, are connected to the first connection opening 37 of the first fixing section 31 or the circuit board holder 10, wherein the first contour area 67 can be in contact with the connection element 17, such as a screw. This enables direct heat transfer, in particular conductive heat transfer, from the base circuit board 150 via the fixing elements 61, 61′, 62, 62′, via a plurality of connection elements 17 into one or more cooling elements 14 in order to advantageously transfer heat from a base circuit board 150 via a Dissipate cooling element 14. Depending on the temperature gradient, heat can of course also be conducted in the reverse order, ie towards the base circuit board 150 .

3b shows a portion of a circuit board holder 10 according to FIG 3a , wherein the fixing elements 61, 61 'are not shown.

Thus is in 3b In particular, a first fixing recess 35, 35' is shown, which is configured to fix a first fixing area 65, 65' of the first fixing element 61, 61' thereto or to arrange it therein.

Furthermore shows 3b a first connection opening 37, by means of which, in exemplary embodiments, a cooling element 14 can be arranged or attached to the printed circuit board holder 10, as shown in FIG 10 shown. In addition, the first connection opening 37 can provide a further fastening option for fixing the printed circuit board holder 10 to a base printed circuit board 150 . In preferred embodiments, a cooling element 14 can be arranged or attached to the circuit board holder 10 by means of the first connection opening 37, and the connection element 17 connected to the connection opening 37 can also contact the base circuit board 150 or come into contact with the base circuit board 150, resulting in a particularly advantageous conductive Heat transfer from the base circuit board 150 via the connection element 17 and via the fixing elements 61, 61 ', 62, 62' towards the connection element 17, and then further to the cooling element 14 are provided. Depending on the temperature gradient, heat can also be conducted in the reverse order, ie towards the base circuit board 150 .

4a shows fixing elements 61, 61′, 62, 62′ of a printed circuit board holder 10, as can be fixed to a printed circuit board holder 10, but without showing the printed circuit board holder 10 as well. 4a shows in particular the sectional configuration of the fixing elements 61, 61', 62, 62'.

Each fixing element 61, 61', 62, 62' has a fastening area 63, 63', 64, 64', a fixing area 65, 65', 66, 66' and a contour area 67, 67', 68, 68' .

Furthermore, in 4a a connection opening axis 91, 92 is shown. In preferred embodiments, the fixing elements 61, 62 are arranged or fixed rotationally symmetrically relative to the fixing elements 61', 62' with respect to the connection opening axis 91, 92. Rotational symmetry with respect to the connection opening axis 91, 92 means that the fixing elements 61, 62 correspond to the fixing elements 61', 62' by rotating about the connection opening axis 91, 92, in particular can correspond to the fixing positions of the fixing elements 61', 62'. Rotational symmetry of the fixing elements 61, 61', 62, 62' with respect to the connection opening axis 91, 92 can be described by means of point symmetry of the fixing elements 61, 61', 62, 62' in an infinite number of sectional planes that run normal to the connection opening axis 91, 92 will.

In preferred embodiments and as in 4a shown, all fixing elements 61, 61', 62, 62' can be identical, in particular geometrically identical or geometrically identical in shape, to one another. In particular, all fixing elements 61, 61′, 62, 62′ can have or consist of the same material, have the same wall thickness, have the same bending radii, and/or have the same geometric shape. Because the fixing elements 61, 61', 62, 62' are identical to one another, the fixing elements 61, 61', 62, 62' can be produced particularly inexpensively and can also be mounted without the risk of confusion or for fixing to a base circuit board 150 can be used. For example, the fixing elements 61, 61', 62, 62' can each have a wall thickness in the range from about 0.15 mm to about 1 mm, preferably in the range from about 0.2 mm to about 0.6 mm.

As in 4a shown, the fastening areas 63, 63′, 64, 64′ of the fixing elements 61, 61′, 62, 62′ can have two soldering openings 97, 97′, 98, 98′ which are configured at least partially before, in particular during a soldering process to be filled with solder, as a result of which the fixing elements 61, 61′, 62, 62′ can be fixed to a base circuit board 150 in a particularly vibration-resistant and secure manner. In addition, the provision of solder openings 97, 97', 98, 98' prevents solder from flowing uncontrolled over the base printed circuit board 150 during a soldering process, so that very clean and simple soldering is made possible.

In alternative embodiments, the fastening areas 63, 63', 64, 64' of the fixing elements 61, 61', 62, 62' can have more or fewer than two soldering openings 97, 97', 98, 98'.

In further alternative embodiments, the attachment areas 63, 63′, 64, 64′ of the fixing elements 61, 61′, 62, 62′ can be configured to liquify during a soldering process and themselves be fixed directly to a base circuit board 150 .

The fixing elements 61, 61', 62, 62' can be produced, for example, in particular by stamping from a metal or metallic material with subsequent bending. The metal or the metallic material that the fixing elements 61, 61', 62, 62' have can in particular be a solderable or solderable metal or at least a metal component.

4b shows a plan view of a portion of a printed circuit board holder 10. In particular, in FIG 4b two first fixing elements 61, 61′ are shown, which are opposite each other in a rotationally symmetrical manner with respect to the first connection opening axis 91, in particular are opposite one another in a rotationally symmetrical manner with respect to the first connection opening axis 91. In particularly preferred embodiments and as in 4b shown by means of a distance arrow in the longitudinal direction I between an outer side of the first fixing element 61' and an opposite outer side of the other first fixing element 61, the fixing elements 61, 61' are preferably arranged at a distance from one another in the longitudinal direction I and on opposite sides of the first fixing section 31 in the width direction b arranged.

In other words, the two first fixing elements 61, 61', in particular the fixing regions 65, 65' of the fixing elements 61, 61', are arranged on opposite sides of the first fixing section 31 in the width direction b, and are spaced apart from one another in the longitudinal direction I, see above that mutually facing sides, in particular mutually facing sides of the attachment areas 63, 63 'of the fixing elements 61, 61', have a minimum distance in the longitudinal direction. The minimum distance in the longitudinal direction I can be in the range of about 0.2 mm to 2 mm.

The spacing of the fixing elements 61, 61' in the longitudinal direction I makes it possible for a large number of circuit board holders 10 to be arranged side by side in the width direction b in a space-saving manner, as in FIG 4c shown, so that a first fixing element 61 of a circuit board holder 10 is arranged in the longitudinal direction with the minimum distance from the first fixing element 61 ′ of the other circuit board holder 10 . In other words, a large number of circuit board holders 10 can be arranged next to one another in width direction b in such a way that a fastening area 63 of a fixing element 61 of a first circuit board holder 10 is essentially aligned in longitudinal direction I with a fastening area 63' of a fixing element 61', as shown in FIG 4b and 11b shown.

Furthermore shows 4b clearly that the tool opening 44 of the tool feed-through element 42 is arranged at a distance from the unlocking recess 72 of the tool feed-through element 70 in the longitudinal direction I.

Furthermore shows 4b that the locking projection 46 is arranged on the elastically deformable locking device 40 and extends in the longitudinal direction I towards the receptacle 24.

Furthermore shows 4b the two positioning elements 52 of a pair of positioning elements 50, each having a positioning projection 54. The two positioning elements 52 are arranged on the elongate receiving body 20, in a front end region of the receptacle 24 in the longitudinal direction, and have a U-shape in their extension in the height direction h. In addition, each positioning element has a positioning projection 54 which extends towards the opposite positioning projection 54, the two positioning projections 54, 54 having a positioning gap in the width direction b as a distance from one another. The positioning gap can correspond to the thickness of a printed circuit board 100, be smaller than the thickness of a printed circuit board 100 or be greater than the thickness of a printed circuit board 100. A positioning gap that is less than or equal to the thickness of a printed circuit board 100 advantageously enables a printed circuit board 100 to be accommodated or arranged in the printed circuit board holder 10 in a particularly vibration-resistant manner by restricting or blocking a deflection of the printed circuit board in the width direction.

Furthermore indicates 4b indicates that the elongate receiving body 20 has thin-walled sections 27 and thick-walled sections 28 alternating in the longitudinal direction I. The wall thicknesses of the thin-walled sections 27 and the thick-walled sections 28 are, as exemplified in FIG 4b shown, not recognizable by the plan view, but the thin-walled sections 27 next to the longitudinally adjacent thick-walled sections 28 spaces for the arrangement of contact elements 18, as well as by 9b clarified. Opposite thick-walled sections 28 of the elongated receiving body 20 can have a clamping gap in the width direction b. The clamping gap can correspond to a thickness of a printed circuit board 100, be smaller than a thickness of a printed circuit board 100 or be greater than a thickness of a printed circuit board 100. A clamping gap that is less than or equal to a thickness of a printed circuit board 100 advantageously allows a printed circuit board 100 can be accommodated or arranged in the printed circuit board holder 10 in a particularly vibration-resistant manner by restricting or blocking a deflection of the printed circuit board in the width direction. The clamping gap can, for example, have a width in the width direction of approximately 0.6 mm to approximately 5 mm, preferably have a width of approximately 0.9 mm to approximately 3 mm, and particularly preferably have a width of approximately 1.5 mm. The alternating arrangement of thin-walled sections 27 and thick-walled sections 28 also makes it possible to provide a large area in order to enable advantageous heat dissipation from the printed circuit board 100 .

5a shows a sectional view of a portion of a printed circuit board holder 10 with a sectional plane parallel to the vertical direction h and to the longitudinal direction I, so that a first fixing recess 35 can be seen.

The first fixing recess 35 can, in exemplary embodiments and as shown in FIG 5a shown T-shaped. In other words, the first fixing recess 35 in the first fixing section 31 can be configured in such a way that it is formed in sections in a section with a section plane parallel to the height direction h and the longitudinal direction I, with the first fixing recess 35 having a greater extension in the longitudinal direction in the height direction h at the top I has than in the height direction h below. A first fixing element 61, in particular a first fixing region 65 of the first fixing element 61, can be fitted from above in the height direction h downwards in the first fixing recess through the T-shaped first fixing recess 35, with respect to a section with the cutting plane in the height direction h and in the longitudinal direction I 35 are arranged, in particular clamp or latch there, or be glued there.

In exemplary embodiments, the fixing area 65, 65 ', 66, 66' of the fixing elements 61, 61 ', 62, 62' by a press fit and / or by locking, in particular locking behind, and / or by gluing, in particular using a special thermally conductive adhesive, in the fixing recess 35, 36 and on the fixing portion 31, 32 are fixed.

Fixing the fixing area 65, 65', 66, 66' of the fixing elements 61, 61', 62, 62' by means of a press fit and/or by latching, in particular by latching behind the fixing recess 35, 36 or on the fixing section 31, 32 can advantageously be simplified if the fixing element 61, 61′, 62, 62′ has or consists of a metallic material and the fixing section 31, 32 has or consists of a polymer material, in other words plastic. This is achieved in that the plastic is deformed or crushed by the metallic material when fixing the fixing area 65, 65', 66, 66' of the fixing elements 61, 61', 62, 62'. This allows the fixing elements 61, 61′, 62, 62′ to be fixed in place on the fixing section 31, 32 in a particularly form-fitting manner. Alternatively or additionally, an adhesive, in particular a particularly thermally conductive adhesive, can be used in order to instead or additionally achieve a cohesive attachment of the fixing elements 61, 61', 62, 62' to the fixing section 31, 32, which above all enables conductive heat transport between the printed circuit board 100, base circuit board 150 and / or cooling element 14 allows.

By fixing the fixing elements 61, 61', 62, 62' in a T-shaped fixing recess 35, 36, with respect to a section with a cutting plane parallel to the height direction h and to the longitudinal direction I as in FIG 5a shown, a deflection or vibration of the circuit board holder 10 in the vertical direction h and in the longitudinal direction I can advantageously be restricted or avoided, whereby a particularly vibration-resistant circuit board holder 10 is provided.

5b shows a sectional view of a portion of a printed circuit board holder 10 with a sectional plane parallel to the width direction b and the longitudinal direction I, so that another view of the first fixing recess 35 can be seen.

The first fixing recess 35 can, in exemplary embodiments and as shown in FIG 5b shown T-shaped. In other words, the first fixing recess 35 in the first fixing section 31 can be configured so that it is formed in sections in a section with a section plane parallel to the width direction b and the longitudinal direction I, with the first fixing recess 35 in the width direction b within the first fixing section 31 a has a greater extent in the longitudinal direction I than in the width direction b towards the outside of the first fixing section 31.

By fixing the fixing elements 61, 61', 62, 62' in a T-shaped fixing recess 35, 36, with respect to a section with a cutting plane parallel to the width direction b and to the longitudinal direction I as in FIG 5a shown, a deflection or vibration of the circuit board holder 10 in the width direction b and in the longitudinal direction I can advantageously be restricted or avoided, whereby a particularly vibration-resistant circuit board holder 10 is provided.

How through the 5a and 5b clarified, the first fixing recess 35 can be T-shaped independently of one another in two sectional planes, which means that a fixing element 35 can be easily installed or fixed, and at the same time advantageously a deflection or vibration of the circuit board holder 10 in the height direction h, width direction b and can be restricted or avoided in the longitudinal direction I, whereby a particularly vibration-resistant circuit board holder 10 is provided.

The above description with regard to the first fixing cutout 35 in connection with the first fixing element 61 applies to all fixing cutouts 35, 35′, 36, 36′ and fixing elements 61, 61′, 62, 62′.

Furthermore shows 5b for example, that a stiffening rib 80 can extend in the longitudinal direction I up to the fixing recess 35 . Since the fixing element 61 is fixed to the fixing recess 35 of the first fixing section 31, a stiffening rib 80, which extends to the fixing recess 35, enables an advantageous flow of forces, in particular between the fixing elements 61 and 62 or on the opposite side in the width direction between the fixing elements 61 'and 62', so that the force can be directed around the printed circuit board 100, which is arranged with the contact section 110 in the receptacle 24, and transmission of vibrations to the printed circuit board 100 can be restricted or avoided.

6a shows a side view of a portion of a printed circuit board holder 10. It is particularly clear that a tool opening axis 45, along which a tool opening 44 extends in a tool feed-through element 42, in particular in a cylindrical manner, is different from an unlocking recess axis 73, along which an unlocking recess 72 extends in a Tool insertion element 70 extends, in particular extends cylindrically. The difference between the tool opening axis 45 and the unlocking recess axis 73 essentially ensures the elastic deformation of the elastically deformable locking device 40, on which the locking projection 46 is arranged, when a tool is passed through the tool opening 44 and inserted into the unlocking recess 72.

6b shows an oblique view of a printed circuit board holder 10. In particular, in 6b two opposing locating members 52 of a pair of locating members 50 can be seen, each locating member 52 having a locating projection 54 extending towards the opposite locating member 52, the locating projections 54, 54 configuring a positioning gap in width direction b.

As in 6b shown, the positioning elements 52 each have a positioning chamfer at the upper end in the height direction b and facing the respective opposite positioning element 52, which facilitates the arrangement of a printed circuit board 100, in particular a contact section 110 of a printed circuit board 100, in the receptacle 24.

Furthermore shows 6b that the positioning projections 54 taper in the extension to the opposite positioning projection 54 following in the height direction h. In other words, the posi positioning projections 54 on upper and lower sides thereof, in each case inclined surfaces, in particular surfaces inclined to one another, so that the positioning projections 54 following the extension in the width direction each have a decreasing cross section.

Due to the tapering positioning projections 54, or the decreasing cross section of the positioning projections 54 along the extension in width direction b, the inclined surfaces on the upper sides of the positioning projections 54 allow additional facilitation, in particular through a guide, when arranging the circuit board 100, in particular a contact section 110 of a printed circuit board 100 in the receptacle 24. Since the underside of the positioning projections 54 is also provided with an inclined surface, blocking or wedging when the printed circuit board 100 is removed from the receptacle 24 is prevented. Thus, by providing the positioning protrusions 54 with inclined surfaces on their upper and lower surfaces, the mounting and removing of the circuit board 100 is advantageously facilitated, and the mounting and removing of the circuit board 100 is prevented from being damaged.

7 shows a sectional view of a portion of a printed circuit board holder 10 with a sectional plane parallel to the vertical direction h and the longitudinal direction I. As in FIG 7 shown, the locking projection 46 extends at its tip facing the receptacle 24 in the longitudinal direction I with an underside that is essentially parallel to the longitudinal direction I. Due to the underside running essentially parallel to the longitudinal direction I, the locking projection 46 enables a locking effect in a locking engagement in a locking recess 120 of a circuit board 100, in particular a locking effect with regard to a movement of the circuit board 100 disengaging from the engagement of the locking projection 46 enables a particularly secure arrangement of the printed circuit board 100 in the receptacle 24, with movement of the printed circuit board 100 in the vertical direction h being restricted or avoided in particular.

Furthermore, in 7 shown by way of example that the tool insertion element 72 can have an unlocking recess 72 which is configured as a blind hole, as a result of which damage to a base circuit board 150 can advantageously be avoided during an unlocking process using a tool.

In addition, shows 7 that the unlocking recess axis 73 of the unlocking recess 72 can run essentially parallel to the tool opening axis 45 of the tool opening 44, the unlocking recess axis 73 being arranged in the longitudinal direction I away from the receptacle 24 at a distance from the tool opening axis 45. The elastically deformable locking device 40 can thus be elastically deformed in the longitudinal direction I away from the receptacle 24 in order to unlock the printed circuit board 100 . The distance between the unlocking recess axis 73 and the tool opening axis 45 in the longitudinal direction I can be, for example, in the range from about 1 mm to about 12 mm, and preferably in the range from about 4 mm to about 9 mm.

8th shows an oblique view of a sectional representation of a partial area of a printed circuit board holder 10.

8th clarifies the preferred configuration of the positioning element 52 with the positioning projection 54, as in connection with FIG 6b described, so that the description of the figures 6b is referenced.

Further clarified 8th the preferred configuration of the locking projection 46, the tool opening 44 with the tool opening axis 45 and the unlocking recess 72 with the unlocking recess axis 73, as in connection with 7 described, so continue to the description of the figures 7 is referenced.

9a shows a view of a first sectional illustration through the elongated receiving body 20 of a printed circuit board holder 10 with a sectional plane parallel to the width direction b and the height direction h.
9a first shows an exemplary subdivision of the elongate holding body 20 in the height direction h, wherein a region of the elongate holding body 20 which is essentially configured to laterally surround the contact region 110 of a printed circuit board 100 in the width direction b is a clamping section 25, and a region of the elongate holding body 20, which is a support section 26 which is essentially in the vertical direction h below the clamping section 25 .

Furthermore shows 9a the receptacle 24, which in particular defines a hollow space or a cavity in order to receive a lower section of a printed circuit board 100, in particular a contact section 110 of a printed circuit board 100 therein. The recording 24 can in particular in section with a section level in the height direction h and in the width direction b, as in FIGS 9a and 9b shows can be configured in a substantially U-shape or V-shape. The receptacle 24 can, for example, extend at the same height as the clamping area 25 of the elongated receptacle body 20 . The receptacle 24 can also have an insertion chamfer at the upper ends of the sides which extend essentially parallel to sides of a circuit board 100 in order to facilitate the insertion of a circuit board 100 into the receptacle 24 .

Furthermore, the receptacle 24 may have a receptacle floor configuring a surface or portion up to which the circuit board 100 may be inserted into the receptacle 24 or the elongate receptacle body 20 . The receiving base can in particular extend essentially parallel to the width direction b and to the longitudinal direction I of the elongated receiving body. Alternatively, the receiving base can be configured in a contoured manner, that is to say the receiving base can in particular have a contour. The receiving floor can also be located in particular at a height which separates the clamping section 25 from the support section 26 in the vertical direction h. In particular, the receiving base can be at a height which precisely separates the clamping section 25 from the supporting section 26 of the elongated receiving body 20 in the vertical direction h.

9a shows first in particular a thin-walled section 27 of the elongate receiving body 20 in contrast to a thick-walled section 28, as exemplified in FIG 9b shown.

The thin-walled section 27 is recessed in sections in the area of the clamping section 26 with respect to the thick-walled section 28, thereby providing a space for arranging a contact element 18, which is configured to contact a contact section 110 of a printed circuit board 100 and optionally also to clamp, and configured a base circuit board 150 is to be contacted at a lower end of the elongated receiving body 20 . In other words, the thin-walled section 27 has a geometry that is recessed in the width direction b compared to the thick-walled section 28 in order to arrange a contact element 18 which contacts or connects both a contact section 110 of a printed circuit board 100 and a base printed circuit board 150 .

As in the 9a and 9b shown, the elongated receiving body 20 has a large number of alternating thin-walled sections 27 and thick-walled sections 28, so that advantageously a large number of contact elements 18, in particular electrical contact elements 18, for contacting a contact section 110 of a printed circuit board 100 can be stably positioned in the gaps between two Thick-walled sections 28 result, are arranged. Thus, a large number of contact elements 18 can be stably connected. the elongate receiving body 20 are arranged.

Furthermore, the alternating thin-walled sections 27 and thick-walled sections 28 of the elongated receiving body 20 can avoid excessive material accumulations of injection-molded material, as a result of which possible distortion when the injection-molded material cools or solidifies can be prevented or reduced.

By preferably arranging a pair of stiffening ribs 80 on both outer sides of the elongated receiving body 20, in particular the opposite outer sides of the elongated receiving body 20 in the width direction b, the vibration resistance and rigidity of the printed circuit board holder 10 can be advantageously increased.

Will, as in the 9a and 9b shown, the stiffening ribs 80 are arranged in the region of the support section 26 of the elongate receiving body 20, the stiffening ribs 80 initially allow a center of gravity of the circuit board holder 10 to be kept low in the height direction h, so that the circuit board holder 10 continues to be advantageously configured in a vibration-proof and rigid manner.

In addition, the arrangement of the stiffening ribs 80 in the area of the support section 26 of the elongate receiving body 20 enables the material flow of injection-molded material to be maintained during the injection molding process, especially in a thin-walled section 27 of the elongate receiving body 20, and enables more uniform cooling. Consequently, the stiffening ribs 80, which are arranged in the area of the support section 26 or adjacent to the support section 26, make it possible for the printed circuit board holder 10 to be configured in a particularly vibration-resistant and rigid manner and at the same time to be manufactured with true shape, i.e. with only little or no distortion , In particular can be injection molded.

9b shows a further view of a first sectional illustration through the elongated receiving body 20 of a printed circuit board holder 10 with a sectional plane parallel to the width direction b and the height direction h. 9b shows in particular a thick-walled section 28 of the elongate receiving body 20 in contrast to the thin-walled section 27, as exemplified in FIG 9a shown.

In 9b Individual contact elements 18 are shown, which are configured as already described above, both a contact section 110 of a circuit board 100, and a base circuit board 150 to contact or to connect contacting. As in 9b indicated, the contact elements 18 can additionally be configured to clamp the contact section 110 of the printed circuit board 100, ie to press against the contact section 110 of the printed circuit board 100 with a prestress in the width direction b.

Furthermore shows 9b a section through the stiffening ribs 80, each stiffening rib 80 having a substantially trapezoidal shape in a cross section or a section with a sectional plane parallel to the height direction h and width direction b. In particular, the stiffening rib 80, as in 9b shown, with a base with respect to. The trapezoidal shape towards the outside of the elongate receiving body 20, in particular an outside in the width direction b of the elongate receiving body 20, configured. In the width direction b opposite the base, the stiffening rib 80 has a shoulder section 82 which extends essentially parallel to the height direction h. As in 9b shown, the stiffening rib 80 can be configured in a section with a section plane parallel to the height direction h and width direction b to taper in the extension in the width direction towards the shoulder section 82, in particular from both in the height direction h above and in the height direction h below. In other words, the upper side surface of the trapezoidal shape of the stiffening rib 80 following the width direction b from the outside of the elongated receiving body 20 can be configured to be inclined downward, and the lower side surface of the trapezoidal shape of the stiffening rib 80 following the width direction b from the outside of the elongated receiving body 20 , be configured inclined upwards. The above-described configuration of the trapezoidal shape of the stiffening rib 80 in a section with a section plane parallel to the height direction h and width direction b can advantageously improve a material flow of injection-molded material during an injection molding process, thereby reducing or avoiding possible distortion of the circuit board holder 10.

10 shows a printed circuit board holder 10 with a cooling element 14 which is arranged on the printed circuit board holder 10 . The cooling element 14 can be used as in 10 shown, in particular connected to the circuit board holder 10 via at least one cooling element connection section 16 .

In exemplary embodiments, the cooling element 14 can have two cooling element connection sections 16 which lie opposite one another in the longitudinal direction I in order to connect the cooling element 14 to the circuit board holder 10 or to the circuit board holder 10 in a stable and vibration-proof manner.

As in the 1 and 3a shown as well as in 10 indicated, a first fixing section 31 can be arranged on the circuit board holder 10 in the longitudinal direction I at the front and a second fixing section 32 can be arranged at the rear in the longitudinal direction I, with the first fixing section 31 having a first connection opening 37 and the second fixing section 32 having a second connection opening 38. Furthermore, the first fixing elements 61, 61' can each have a first contour region 67, 67', which runs in sections along the contour of the first connection opening 37, so that when the cooling element 14 is connected by means of a connection element 17 to the circuit board holder 10, in particular to the first fixing section 31, which has the first connection opening 37, both the first fixing elements 61, 61' can contact the connection element 17, and the cooling element connection section 16 can contact the connection element 17. An advantageous conductive heat transfer between the first fixing elements 61, 61' and the cooling element 14 can thus be provided. Since the fixing elements 61, 61' are configured to be fixed to a base circuit board 150, an advantageous conductive heat transfer between the base circuit board 150 and the cooling element 14 can accordingly be provided.

The cooling element connection section 16, as in 10 shown, can in particular be configured to touch the first fixing elements 61, 61' in the state of arrangement on the circuit board holder 10, in particular to touch an upper side in the height direction h of the first contour regions 67, 67' of the first fixing elements 61, 61'. A conductive heat transfer between base circuit board 150 and cooling element 14 can thus be further improved.

As in 10 indicated, the cooling element 14 can preferably extend along the elongated receiving body 20 and have one or more cooling fin(s) 15 . The one or the several Cooling fin(s) 15 can be configured to extend in the width direction b from the cooling element 14 to a printed circuit board 100 and optionally contact the printed circuit board 100 in a state arranged in the receptacle 24 . A direct contact of the printed circuit board 100 with one or more cooling fins 15 provides an advantageous direct conductive heat transfer from the printed circuit board 100 to the cooling element 14 . Accordingly, using the cooling element 14, as in 10 shown, an advantageous cooling of the circuit board 100 can be provided.
