Definitions
- the invention is based on electromagnetic shielding for printed circuit board connectors according to the generic type of independent claim 1.
- the invention is also based on a printed circuit board connector having electromagnetic shielding. Shields of this type are required in order to ensure/increase data integrity during transmission from a printed circuit board, also referred to as printed circuit board or circuit board, to a conductor and/or another printed circuit board connected to the printed circuit board.
- the electromagnetic compatibility (EMC) can be significantly increased by a shielding element, as a result of which the data transmission rate can also be stabilized and/or increased. For a particularly positive effect, a circumferential, so-called 360° shielding is aimed for. State of the art
- a circuit board connector with shielding elements above and below the contact elements/contact element rows is often chosen as a makeshift solution, with the external contact elements of the circuit board connector being connected to a protective conductor (PE) or ground connection in order to simulate a circumferential shielding.
- PE protective conductor
- a particular disadvantage of this proposed shielding is the need for at least two sheet metal frames that are complementary to one another.
- the object of the invention is to provide a more cost-effective and space-saving shield for printed circuit board connectors compared to the prior art, which can also be used more universally.
- Another object of the invention is to provide a printed circuit board connector equipped with improved shielding.
- the shielding according to the invention is formed from an electrically conductive material and is intended for use in a printed circuit board connector.
- the shielding is formed from at least two shielding elements, each of which has at least two shielding contact receptacles, at least two shielding contact elements and at least one fastening form for connection to a housing of the printed circuit board connector, as well as at least one printed circuit board contact for establishing an electrically conductive connection with the printed circuit board to be contacted, with the Screen elements each have at least a first side element and a second side element, which are connected to one another by at least one deformed area.
- Circuit card connectors are connectors that contact a circuit card, also known as a printed circuit board or printed circuit board, and, through connection with a mating connector, enable the transmission of electrical and/or electronic signals and/or energy to at least one other circuit card or conductor, usually in the form of (shielded ) allow cables.
- Components of the shielding are referred to as shielding elements, which are designed as individual components and in combination form the unity of the shielding.
- the concept of receiving the shield contact is to be understood as meaning a shaping of the shield elements which at least facilitates contacting of the shield contact elements, for example by means of a wedge-like guide contour.
- the screen contact elements are therefore provided in particular for making contact with a screen of a mating connector.
- a form of fastening is to be understood as an omission and/or a shape which enables the shielding element to be fixed in a region of the housing provided for this purpose.
- the term printed circuit board contact means an area and/or a shape of the shielding element which can be connected to a printed circuit board, for example by soldering.
- the areas usually provided for this purpose on printed circuit boards are also called solder pads referred to and are usually designed as connectable with solder contact points.
- Partial areas of the umbrella element are to be understood as a side element.
- a screen element is formed from at least two side elements which are connected by a deformed area.
- a forming area is to be understood as an area in which the various planes in which the side elements run intersect. In the case of a straight printed circuit board connector, this angle is preferably between 85° and 95°.
- the shielding according to the invention enables a particularly simple all-round shielding of the printed circuit board connector due to the simple design of the shielding elements.
- the shielding elements are constructed essentially in the same way. This embodiment is a particularly cost-effective
- This embodiment can be used particularly advantageously for straight printed circuit board connectors.
- the shielding can be used particularly advantageously by means of shielding elements that are essentially structurally identical in the area of the hermaphroditic plug connector.
- a further embodiment proposes that the screen contact receptacle and the screen contact element are arranged alternately along at least one side of each screen element.
- This embodiment enables use in the field of hermaphroditic connectors.
- known male/female connectors can also be provided with identical shielding.
- the structurally identical design with alternating shield contact mounts and shield contact elements thus creates a hermaphroditic shielding, which at the same time fulfills the function of all-round shielding.
- the first side panel has at least one attachment form and the second side panel has at least one attachment form. Depending on the design of the printed circuit board connector, it is thus ensured in any case that the forming area is not overstressed by uneven loading during a plugging process and is therefore possibly damaged.
- a printed circuit board connector can be provided with a particularly simple outer shell, the connection of which to an insulating body consists of simple webs. These forms of attachment, which are designed as recesses, can be brought into engagement with these webs in a simple manner.
- An alternative embodiment has a shield contact receptacle with an inner side, the inner side extending from a plane in which the shield contact receptacle is connected
- a further alternative embodiment has a shield contact element with an inner side, the inner side being remote from a plane in which the side element connected to the shield contact element is located.
- this has a positive effect on contacting the side element of a shielding element of a mating connector, since the Screen contact element is increasingly introduced to said screen element during a plugging process.
- An embodiment is particularly advantageous in which the shield contact element and the shield contact receptacle move away in mutually different directions from a plane in which the side element connected to the shield contact element and the shield contact receptacle is located.
- the shield contact element has a contact shape area at its end opposite the side element, which describes at least one curved shape.
- this curve shape can be designed for improved contacting.
- the curved shape in combination with a shield contact recording can also be shaped for an improved sliding movement during a mating process.
- a preferred, alternative embodiment provides that the contact shape area of the shielding contact element essentially describes an S shape.
- a shield contact element designed in this way allows the advantages mentioned above to be combined. The foremost area facilitates the sliding movement of the shielding contact element over the shielding contact receptacle of a mating connector, while the area adjacent thereto inclines in an arc shape toward a side part of a shielding element to be contacted. So after initially simplified
- the invention is also based on a printed circuit board connector with a housing, at least one contact receptacle for accommodating at least one contact element, the housing having at least two shield receptacles which are provided for accommodating a shield.
- Circuit card connector is preferably a straight circuit card connector.
- the printed circuit board connector is particularly advantageously designed as a hermaphroditic printed circuit board connector.
- one embodiment recommends designing the shield mounts as point-symmetrical cavities in the housing, which are arranged between the outer wall of the housing and the at least one contact mount.
- This embodiment is particularly advantageous when using structurally identical shielding elements of the shielding.
- Hermaphroditic connectors can be equipped in this way in a particularly advantageous manner.
- FIG. 1 shows a perspective representation of a screen element
- Fig. 2 is a perspective view of a hermaphrodite
- FIG. 3 is a plan view of a mating face of a hermaphroditic printed circuit board connector with a shield;
- Fig. 4 is a perspective view of a shield without a board connector on a board
- FIG. 5 shows a perspective view of two identical shields without circuit board connectors, each on a circuit board.
- the figures contain partially simplified, schematic representations. In some cases, identical reference symbols are used for the same but possibly not identical elements. Different views of the same elements could be scaled differently. Directions such as “left”, “right”, “up” and “down” are to be understood with reference to the respective figure and can vary in the individual representations compared to the object represented.
- FIG. 1 shows a single shielding element 2 of the shielding 1 in a perspective representation.
- the forming area 3 can be seen clearly between the side elements which are aligned essentially orthogonally to one another, shown as the first side element 20 and the second side element 21 .
- a printed circuit board contact 4 designed as an extension is visible in the lower area of the shielding element 2 .
- This printed circuit board contact 4 is designed to be brought into an electrically conductive connection with a soldering area of a printed circuit board to be connected thereto.
- Fastening forms 5 which are designed as recesses, are provided in the lower region at basically uniform intervals along the first side element 20 and the second side element 21 .
- the fastening forms 5 are provided with a funnel-shaped entry opening and an undercut into which a retaining pin or similar retaining element of the housing 11 can be inserted and fixed.
- shield contact receptacle 6 and shield contact element 7 are arranged in alternating order.
- the screen contact recordings 6 are designed at least on the one hand with a bevel. The slope runs from a plane in which the respective side element, ie the first side element 20 or the second
- Side element 21 is arranged and moves away from this plane towards its upper end, from a center point of the screen element 2 board connector used away.
- This incline of the shield contact receptacle 6 is achieved, for example, by a forming process, for example a bending process. Alternatively, a machining process, for example milling to introduce a chamfer, can also be achieved. Also the
- Screen contact elements 7 are arranged at an angle on the first side element 20 and the second side element 21 . In the illustrated embodiment, the screen contact elements 7 leave the plane in which the respective side element lies in a direction opposite to the exit side
- the shield contact elements 7 have a contact form area 8 at the end which is arranged distally to the shield element 2.
- the contact form area 8 essentially has an S-shape. This design of the contact form area 8 enables a simplified plugging of a printed circuit board connector with a shielding 1 according to the invention, with improved contacting of the shielding contact element 7 with the shielding element 2 being achieved at the same time.
- FIG. 2 shows an exemplary configuration of a printed circuit board connector 10 according to the invention with a shield 1 according to the invention.
- Printed circuit board connectors are used in particular for connecting a printed circuit board to another printed circuit board in a parallel arrangement to one another.
- An example of this is the arrangement of a so-called daughter board, also known as a mezzanine board, on a main circuit board, often referred to as a motherboard.
- the housing 11 of the printed circuit board connector 10 has two cavities which function as a shield mount 13 . In this screen shots 13 is the Shield 1 inserted. From the surrounding housing 11, only the printed circuit board contacts 4 protrude from the shielding 1 at the bottom. In the upper section of the housing 11, the shield contact receptacles 6 do not protrude at best, or at least only slightly, while the shield contact elements 7 at least essentially reach the height of the contact receptacles 12.
- the printed circuit board connector 10 is provided with various contact receptacles 12 and 12', with the contact receptacles 12 each receiving two contact elements 14 and the contact receptacles 12' each receiving one contact element 14.
- the contact elements 14 are also advantageously designed as hermaphroditic contact elements.
- FIG. 3 shows a printed circuit board connector 10 as shown in FIG. 2, but in a view from above, more precisely with a view of the mating face.
- the shielding 1 is clearly made up of two identical, hermaphrodite shielding elements 2 .
- the housing 11 of the circuit card connector 10 has two shielding receptacles 13 which are formed as shielding elements 2 receiving cavities.
- the housing 11 has a guide element 15 in diagonally opposite corners of the housing 11 .
- These guide elements 15 simplify a plug-in process with a mating connector, which in the example shown can be of identical design.
- the screen contact recordings 6 are, for example by a forming process such as rolling, designed in such a way that a chamfer on your side pointing towards the plug-in face simplifies a plug-in process.
- the screen contact elements 7 have an S-shaped form of contact area 8, which has a top curve in the direction of the mating face of the printed circuit board connector 10.
- FIG. 4 shows the use of a shield 1 on a printed circuit board 9, with the surrounding printed circuit board connector 10 being left out.
- the circuit board 9 has circuit board contact surfaces 90, which at the Shield 1 arranged printed circuit board contacts 4 contact. This contact is usually cohesively fixed by a solder.
- the two structurally identical shielding elements 2 of the shielding 1 are L-shaped, with the deformed region 3 allowing the first side element 20 and the second side element 21 to be separated from one another.
- FIG. 5 shows two printed circuit boards 9 and 9', each of which is equipped with a shield 1.
- the associated printed circuit board connectors 10 have been left out, as in FIG. 5, for a better overview. It is clearly shown that the shield contact elements 7 of the shield 1 slide over the shield contact mounts 6' of the opposite shield V and contact the respective opposite shield elements 2' on the first side surface 20' or the second side surface 21'.
- the advantage of designing the shields 1 and 1' as a hermaphroditic shield also becomes clear.
- Four shielding elements 2 of the same type can easily and inexpensively achieve the all-round shielding of two corresponding, straight printed circuit board connectors 10 .
