Description

The invention relates to a system for realizing a lamp according to the preamble of claim 1.

Generic systems have, as two basic components, a mounting rail that is elongated in a longitudinal direction and a mounting body that is elongated in the longitudinal direction. Supply lines are usually arranged on the mounting rail, and an illuminant and/or other functional element is usually arranged on the mounting body, such as radio modules, control gear, etc. The mounting rail is typically used to fix the light to a component, for example a ceiling. When installing a lamp, the mounting rail is usually first attached to the component and then the mounting body, which is equipped with the elements or components of the lamp mentioned that require a corresponding electrical supply, is fixed to the mounting rail, so that the mounting rail and mounting body form an interior space in which essential elements, in particular functional elements of the lamp, are arranged, for example circuit boards with LEDs, operating devices, radio modules, supply lines, etc. Depending on the embodiment, the respective lighting means can also be arranged or fastened on the underside of the assembly body, such as an LED circuit board. Typically, the support rail and mounting body are each designed to be elongated in a longitudinal direction. The support rail usually has a cross section perpendicular to the longitudinal direction, which is open along a vertical direction at a vertical end and is delimited along a transversal direction by two side walls which are connected to one another by a bottom section of the support rail running along the transversal direction. The mounting rail is usually attached to a component via its bottom section. The mounting body is usually arranged on the open vertical end of the mounting rail, so that the mounting body together with the mounting rail forms an interior space which is closed off by the mounting rail and the mounting body running around it perpendicular to the longitudinal direction, with the enclosure of the interior space being able to be interrupted in sections, of course, for example to enable an air supply. A generic system usually comprises a longitudinally elongated power conducting rail, which has channels in which conductor wires are arranged, and an electrical contact device with a mounting section and a vertical direction spaced from the mounting section contact section and in a transverse direction (Y) perpendicular to the longitudinal direction and perpendicular to the vertical direction spaced side wall sections. As a rule, these side wall sections can include areas of the mounting section as well as areas of the contact section of the contact device. In an operating position of the components, also called parts, of the system, in which the components of the system have an operating position that characterizes The two basic components are fastened to one another, with the conductor rail being fastened to a first of the two basic components and the contact device being fastened with its mounting section to a second of the two basic components and being electrically conductively connected with its contact section to at least some of the line wires. In most cases, the current-conducting rail is fastened to the mounting rail in the operating position, in particular to the bottom section of the mounting rail. However, it is also conceivable that the current conducting rail is fastened to the mounting body in the operating position. The basic principle of the current conducting rail is to allow contact over a longitudinal section, so that contact can be made between supply lines arranged on the mounting rail and the components arranged on the mounting body within a specific longitudinal section and not just at a single longitudinal position. For example, the mounting section of the contact device can be fixed in the operating position on the mounting rail and the contact device can be electrically conductively connected to electrical supply lines arranged on the mounting rail, while the current conducting rail is arranged on the mounting body and the contact section of the contact device engages in channels of the current conducting rail and contacts the line wires arranged in the channels, which in turn are connected to components arranged on the mounting body to supply the components.

Alternatively, for example, in the operating position of the components of the system for realizing a lamp, the current-carrying rail can be arranged on the mounting rail, wherein the line wires arranged in the channels of the current conducting rail form at least one section of supply lines which are arranged in the mounting rail, the mounting section of the contact device being fixed to the mounting body and the contact section of the contact device engaging in the channels of the current conducting rail arranged on the mounting rail for contacting the line wires arranged therein, and the contact device being electrically conductively connected at the same time to components which are arranged on the mounting body in order to supply these components. In principle, the contact device thus enables the supply of components arranged on the mounting body by enabling an electrical connection between the supply lines arranged on the mounting rail and the components. In addition to energy supply lines, these supply lines can also include control or data lines. It should be noted that in order to reach the operating position, the assembly body and the support rail are moved toward one another along a vertical direction that is perpendicular to the longitudinal direction until they are arranged on one another and fixed to one another. The person skilled in the art is familiar with common retaining springs, via which a mounting body can be fixed relative to a mounting rail. Typically, such support springs have a bottom portion for mounting on the mounting body and, at both transverse ends of the bottom portion, a holding portion extending vertically away from the bottom portion, on which a holding projection extending outward in the transverse direction is provided. This holding projection typically engages behind a fastening projection which is arranged on one of the side walls of the mounting rail associated with the holding projection. Often this is the assembly body itself is formed to have a cross section perpendicular to the longitudinal direction in a U-shape manner, thus comprising a bottom portion and two side wall portions, often the bottom portion of the retaining spring being fixed to the mounting body by clamping the bottom portion to projections provided on the side wall portions of the mounting body, thereby pressing the bottom portion of the retaining spring against the bottom portion of the mounting body. However, other fastening options are also known, for example by means of screwing, latching or by means of bayonet catches, via which a mounting body can be fixed to the mounting rail. In general, suitable fastening means, with which the mounting body is fastened to the mounting rail in the operating position, preferably serve to prevent the mounting body and mounting rail from moving away from each other vertically, starting from the operating position.

The EP 3 477 791 A1 describes a tap connector with an insulating housing and with contact elements for electrically conductive contacting of electrical conductors of a current-carrying profile, the tap connector being plugged onto the current-carrying profile. The tap connector has a conductor bracket that carries multiple leads for connecting the leads to a ballast. The connection lines extend overhung between a contact element and a slot in the conductor holder. The EP 3 477 792 A1 also relates to a pick-off connector for a current-carrying profile, with a sheet metal element of a protective earth contact being designed to rest on the pick-off connector. The EP 1 361 632 A1 relates to a carrier element for contact spring elements, which are used for contacting a plurality of conductor wires are provided, which run in the longitudinal direction of a cross-sectionally U-shaped conductor rail. For its attachment, the support element has attachment means for attachment to the conductor rail or to attachment parts thereof. In this case, the carrier element is designed in such a way that it itself provides a free space that can be used for the passage of additional wires or lines.

In principle, a large number of common contact devices are known in the prior art, via which contacting between the mounting body and mounting rail or between components arranged on the mounting body and supply lines arranged on the mounting rail is possible by means of a current conducting rail. The contact devices are often designed in such a way that they have contact sections with which they can be inserted into the channels of the current-conducting rail. For example, it is known to fasten a fixed pick-off to a current-conducting rail, which makes contact with the conductor wires arranged in the channels of the current-conducting rail, this tap forming the contact section of the contact device and being connected to a mounting section via a respective cable, with the current-conducting rail and mounting section being fastened to different basic components. Contact devices are also known, which are to be attached to one of the two basic components with their mounting section, with the current conducting rail being attached to the other of the two basic components and the contact device having electrical contact sections such that when the mounting body and mounting rail are brought together vertically, the contact sections are inserted into the channels of the current conducting rail and contact the conductors arranged therein. In order, for example, to contact functional elements such as control gear, lamps, radio modules, etc. arranged at other longitudinal locations on the mounting body and for the contact device in terms of supply and/or control technology, the system has additional lines that extend in the longitudinal direction and are therefore attached to one of the components of the luminaire. This lamp wiring can be done, for example, below the contact device between the contact device and mounting body, as for example in the European patent application EP 2 365 597 B1 is described. This teaches the provision of wire holders that are attached to a mounting plate and are sufficiently secured against twisting, so that manual or automatic assembly using a robot is made possible. However, the wire holders described in the prior art require an additional work step for attaching the respective wire holder to the mounting plate, which increases the effort involved in constructing the lamp. If the wiring is arranged laterally on the contact device, on the other hand, there is a risk that lines will be crushed and damaged as a result when the operating position of the components is set, in particular when the mounting body is fixed to the mounting rail. Furthermore, when assembling the components of the system to adjust the operating position of these components, the lines may unintentionally engage undercuts or recesses of the components or interfere with protrusions of the components, so that assembly of the system and thus adjustment of the operating position of the components is then prevented.

In this respect, the present invention is based on the object to modify a generic system for the realization of a lamp in such a way that the assembly of the system is simplified.

This object is achieved by the present invention with a system having the features of claim 1. The system according to the invention, which is suitable for realizing a light, comprises two basic components: a mounting rail that is elongated in a longitudinal direction and on which supply lines are arranged, and a mounting body that is elongated in the longitudinal direction and on which at least illuminants and/or other functional elements such as an operating device for feeding the illuminant or a radio module for providing communication with a data terminal are arranged. Functional elements of this type are to be supplied, in particular, electrically, so that the system according to the invention has a current-conducting rail which is elongated in the longitudinal direction and on which the conductors are arranged, the current-conducting rail having channels in which the conductors are arranged, and an electrical contact device having a mounting section and a contact section which is offset in a vertical direction in relation to the mounting section. The electrical contact device also has side wall sections that are spaced apart in a transverse direction, which runs perpendicular to the longitudinal direction and perpendicular to the vertical direction, which, depending on the embodiment, can include both areas of the mounting section and areas of the contact section. It should be pointed out that these side wall sections do not have to be flat and continuous, but can generally mean lateral delimiting structures of the contact device in the manner of a side section. In an operating position of the components of the system according to the invention the two basic components support rail and mounting body are fastened to one another, the mounting section and the contact section of the contact device are also fastened to one another. Depending on the embodiment, the mounting section and contact section of the contact device can be designed as two separate components that are combined with one another to form a coherently fixed component, but they can also be designed together as a component that is produced in one piece. In its operating position, the current conducting rail is attached to a first of the basic components, and in the operating position the contact device is attached with its mounting section to a second of the two basic components and is electrically conductively connected with its contact section to at least some of the conductor wires of the current conducting rail.

In a preferred embodiment of the system according to the invention, in the operating position of the components of the system, the current conducting rail is fixed to the mounting rail and the mounting section of the contact device is fixed to the mounting body, ie fastened. Particularly preferably, the mounting body and support rail are fastened to one another in the operating position by fastening means which prevent relative movement of the mounting body along the vertical direction away from the support rail. Mounting body and support rail are particularly preferably designed to correspond to one another such that they are guided against one another along the vertical direction to reach the operating position until they reach a vertical end position, wherein they are fixed to one another in this vertical end position by fastening means. According to the invention, the second basic component has a bottom section and two side wall sections extending away from the bottom section along the vertical direction, with the mounting section of the contact device against the bottom section in the operating position is pressed on the second basic component, in particular held on the mounting body. According to the invention, the contact device has a conductor holding device on at least one of its side sections or side wall sections spaced apart in the transverse direction, comprising at least two retaining brackets spaced apart in the longitudinal direction and each having a gap in the vertical direction, which can also be referred to as an interruption, the gaps in the retaining brackets being spaced apart from one another in the vertical direction and the retaining brackets for holding and/or gripping lines running in the longitudinal direction, which can also be referred to here as conductors and in particular can also have insulation, in particular in the form of a sheath Hungarian The specified retaining brackets have a predetermined extension in the longitudinal direction on the at least one side wall section of the contact device, so that such a retaining bracket is also referred to below as a retaining bracket section or longitudinal section. In principle, such a retaining bracket can also have other gaps in addition to the gap specified in the vertical direction.

The system according to the invention can have at least one or more additional features that are specified above in connection with the description of generic systems.

On the one hand, the system according to the invention has the advantage over conventional systems that the contact device has a conductor holding device in the area of at least one of its sides or side sections, which is in particular designed integrally with a section of the contact device, regardless of whether the contact device itself is designed in one piece or in multiple parts, so that the attachment of wire holders described in the prior art on the mounting body or the mounting plate can be omitted. In particular in such embodiments in which the contact device is first connected to the mounting body in the region of its mounting section during assembly of the system according to the invention, a respective longitudinal conductor can first be inserted into the conductor holding device of the contact device provided according to the invention and then the mounting body with the contact device attached to it can be connected to the mounting rail of the system by moving vertically towards one another, without there being a risk that parts of the mounting rail protruding inwards in the transverse direction will engage in one of the gaps in the mounting brackets and thus prevent the operating position from being reached, since the Gaps in the longitudinally spaced headband or headband longitudinal sections are shifted to one another in the vertical direction. In this embodiment, this prevents longitudinal edges or projections extending in the transverse direction from getting caught in the gaps in the conductor holding device when the mounting rail and mounting body with the contact device attached to it are joined together vertically, provided that the mounting rail and mounting body are initially aligned vertically parallel to one another and then moved vertically towards one another.

Further advantageous features and developments of the invention are specified in the following general description, the figures, the description of the figures and the dependent claims.

Preferably, the provision of a plurality of retaining brackets such as two retaining brackets can be provided, which provide a closed retaining section, in particular in a plane that is spanned by the vertical direction and the longitudinal direction, which is interrupted at a single point in the form of the designated gap, so that in the area of these gaps, the respective conductor can be introduced into the holding section of the respective holding bracket, in particular by means of a robot, so that the respective conductor is securely held and/or encompassed within the holding bracket or holding bracket sections.

It can expediently be provided that each of the holding brackets or longitudinal sections of the holding bracket defines a respective holding section in which lines or conductors running in the longitudinal direction are retained or encompassed. It can preferably be provided that a holding bracket arm section extends essentially in the vertical direction, it being possible for this section to be interrupted in the vertical direction by the specified gap or interruption.

The conductor holding device of the contact device in the system according to the invention is not limited to the provision of two longitudinally spaced retaining bracket sections; instead, one or more further retaining brackets, each with a predetermined longitudinal extent, can be provided between the two longitudinally spaced outer retaining bracket sections with a predetermined longitudinal extent, with the gaps in the at least two retaining bracket sections preferably lying on an imaginary straight line in a plane spanned by the vertical and longitudinal directions. As a result of this measure, a predetermined guidance of the line or conductor running in the longitudinal direction is defined over the entire longitudinal extent of the contact device. In addition, the manual or automatic insertion of the conductor into the conductor holding device can be carried out by a simple linear movement, in particular a pure longitudinal movement of a robot blade relative to the mounting body, in order to insert the line or conductor into the at least two retaining bracket sections or retaining brackets.

In one embodiment, which is not according to the invention and is only used for illustration, it can be provided that the plurality of longitudinal sections of the retaining clip of the conductor retaining device of the contact device follow one another without gaps, resulting in a retaining clip that is continuous in the longitudinal direction, so that the lines or conductors are provided in the longitudinal direction of the contact device over the entire longitudinal extent of the conductor retaining device, in particular the contact device. In this example, it can expediently be provided that the gap in the longitudinally continuous holding bracket corresponds approximately to the robot blade in its vertical extension so that it can insert the respective conductor into the holding section of the holding bracket through the opening provided by the gap. In this example, in which the gap in the mounting bracket lies in a plane spanned by the vertical and longitudinal directions on a straight line that does not run parallel to the longitudinal direction, the movement of the robot blade then takes place on this straight line, which in turn ensures that no projections or edges of the mounting rail running in the transverse, i.e. transversal direction, come into engagement with a gap in the respective mounting bracket when the mounting body with the contact device attached to the mounting rail is assembled.

In a particularly expedient embodiment, it can be provided that a respective retaining bracket, in particular all retaining brackets that are spaced apart from one another in the longitudinal direction, are designed to be elastically deflectable in sections in the longitudinal direction in order to enlarge the respective gap in the vertical direction, so that a conductor can be introduced into the retaining region(s) of the conductor retaining device by a purely longitudinal movement of an associated robot blade, which inserts a respective conductor into the introduces holding areas.

Appropriately, it can be provided that the gap of a respective retaining bracket in its vertical extent in its rest position without applying an elastic deformation force in the longitudinal direction when inserting a line into the respective retaining area is smaller than the diameter of the line to be inserted, so that it is trapped in the respective retaining area of the respective retaining bracket.

In order to provide corresponding holding areas in the longitudinal direction, it can expediently be provided that holding areas formed by the holding brackets or longitudinal sections of the holding bracket are arranged in alignment with one another in the longitudinal direction. Depending on the embodiment, these holding areas can be oval or rectangular, for example.

Particularly in those embodiments in which retaining bracket sections are designed to be elastically deflectable for the introduction of the lines or conductors running in the longitudinal direction into the contact device, it can expediently be provided that a respective retaining bracket section of the at least two retaining brackets or longitudinal retaining bracket sections has vertical arm sections which are assigned to one another and are spaced vertically from one another to provide the respective gaps, with at least one of the vertical arm sections delimiting the holding area for holding lines or conductors running in the longitudinal direction in the transverse direction. In particular, in this embodiment, a respective longitudinal section of the headband can have two vertically spaced vertical arm sections, with the self-supporting vertical extent of one vertical arm section preferably being more than twice, in particular more than 2.5 times, the self-supporting vertical extent of the other vertical arm section. However, it should be noted that, according to the invention, one of the cantilevered vertical arm lengths can also have a negligible extent, with the statement "cantilevered vertical extent of a vertical section of a holding bracket" meaning the vertical length of the arm for defining the holding area in the vertical direction.

In order to simplify the introduction of a conductor or a line in the longitudinal direction into the holding areas of the longitudinal sections of the holding bracket, in particular by providing reduced friction between a robot blade and the respective vertical arm sections, it can be provided that end faces of the vertical arm sections assigned to one another, which are spaced opposite one another in order to provide the respective gaps in a holding bracket, are formed approximately parallel to one another and at an acute angle to a plane which is spanned by the longitudinal direction and the transverse direction. The specification "end faces" means the sections of the two vertical sections for defining the spacing or gap, which lie opposite one another for defining this gap.

In the system according to the invention, the conductor holding device of the contact device can preferably be designed in such a way that an imaginary connecting line through the gaps in the retaining brackets or longitudinal sections of the retaining bracket has an angle of ≧8°, in particular ≧10°, particularly expediently ≧13°, to the longitudinal direction. It is assumed here that said connecting straight line runs centrally through the respective gap of the respective headband or headband longitudinal section.

In order to make it easier to insert the respective cable into the holding area of a respective retaining clip of the ladder retaining device, it can expediently be provided that at least one vertical section of a respective retaining clip can be deflected elastically in the longitudinal direction from an operating position in order to increase the respective spacing of the associated vertical arm sections in the vertical direction. Elastic deflection of a vertical section in the longitudinal direction means an elastic bending of the section in such a way that the free end of the vertical section is offset in the longitudinal direction with respect to its rest position, in particular its force-free position. This embodiment is particularly expedient in those cases in which the respective retaining clip or retaining clip longitudinal sections have at least two vertical arm sections, between which a vertical spacing is fixed, so that the elastic deflection of one of these vertical arm sections in the longitudinal direction enables the vertical spacing to be increased for the introduction of the line or conductor that is held in the longitudinal direction in the conductor holding device. However, it is also within the limits According to the invention, both vertical arm sections can be designed to be elastically deformable in the longitudinal direction, so that, for example, a robot blade can be guided longitudinally in such a way that when the conductor or line is introduced into the holding area, both vertical arm sections or their free ends are elastically deflected in the longitudinal direction, i.e. in the direction of the movement of the robot blade.

In a particularly expedient embodiment of the system according to the invention, the conductor holding device of the contact device can be designed in such a way that a respective retaining bracket or longitudinal section of the retaining bracket is formed in such a way that, starting from a rest position, i.e. a position in which no longitudinal forces act on a vertical arm section of the retaining bracket or longitudinal section of the retaining bracket, the vertical interruption is <3 mm, with the vertical interruption being caused by elastic deflection in the longitudinal direction of at least one area of the retaining bracket or longitudinal section of the retaining bracket of the headband or the longitudinal section of the headband can be converted to a value >7 mm, in particular >9 mm. As the person skilled in the art recognizes, a respective geometric design of the ladder holding device or the retaining clip and/or a corresponding choice of material and thus its physical size can be selected for the implementation of this feature, with the specified values being achieved without the strength limits of sections of the ladder holding device or retaining clip being reached or the risk of the material breaking.

For the precise design of a respective headband section can be provided that the vertical arm sections of the respective headband by means of an associated crossbar section with an associated side portion of the Contact device are connected, wherein the vertical arm sections, these associated crossbar sections of the respective headband and the side portion of the contact device form or define the respective holding area of the respective headband. As already shown, it can expediently be provided that the holding area is closed in a plane which is spanned by the vertical direction and the transverse direction, except for the indicated gap between the vertical arm sections.

Depending on the embodiment, the contact device can be designed in one piece, comprising the contact section and the mounting section, or in several pieces, in particular in two pieces, in which case the mounting section is provided by a mounting part and the contact section by a contact part, and the two parts can be connected to one another. Provision can preferably be made for the conductor holding device, comprising the at least two holding brackets or holding bracket longitudinal sections, to be arranged on the contact part. This embodiment is particularly useful in cases where the contact part is made as a single injection molded part from plastic, it being possible for the conductor holding device to be made integral with the contact part. In this embodiment it can be provided that the mounting part is designed as a bent sheet metal part, which is designed for connection to the mounting body, wherein the mounting body can also be designed as a bent sheet metal part in one embodiment. In a particularly expedient embodiment, it can be provided that the contact part and mounting part of the contact device can be brought into engagement with one another in such a way that they are designed to be displaceable relative to one another in the longitudinal direction in a mounting position in an associated operating position, these are fixed to one another.

In one embodiment, in order to be able to bring the mounting body with the contact device attached to it into engagement with the mounting rail by a simple relative vertical movement to one another, it can expediently be provided that the retaining brackets or retaining bracket longitudinal sections are rounded in the vertical direction in their end section facing the mounting rail, in particular in such a way that a respective transition region between a transverse web section and the associated vertical arm section of the retaining bracket or retaining bracket longitudinal section is rounded on the outside.

In a particularly expedient embodiment of the system according to the invention, it can be provided that the side wall section or side section of the contact device, on which the conductor holding device is arranged, comprises at its longitudinal ends a respective tab extending in the transverse direction, in which a respective holding bracket or holding bracket longitudinal section is formed.

In such embodiments, in which the contact section and the mounting section of the contact device are designed as individual components that can be connected to one another, it can expediently be provided that the contact section of the contact device has a connecting device on each of its side wall sections (long sides) for engaging with an associated connecting device on one of the side wall sections of the mounting section of the contact device. For example, it can be provided that such a connecting device has at least one projection extending in the transverse direction and the associated connecting device has a flange which extends in the transverse direction and which the projection engages under in the operating position in order to provide a form fit which is effective in the vertical direction between the mounting section and the contact section.

figure 1 is a schematic diagram of a system designed according to the invention, the sectional plane perpendicular to the Longitudinally X is where the system and thus all system components are in the operating position. The system comprises a mounting rail 1 that can be fastened to a component such as a ceiling, and a mounting body 2. In the embodiment described, both the mounting rail 1 and the mounting body 2 have a U-shaped cross section perpendicular to the longitudinal axis, which is formed by a bottom section and side wall sections. in the in figure 1 The operating position shown is the mounting body 2 on the mounting rail 1 by an in figure 1 fastening means, not shown, such as a retaining spring, is held in such a way that the mounting body 2 is pressed with its side wall sections 21 along the vertical direction Z against projections formed by the side wall sections of the support rail 1 . In the operating position of the components of the system according to the invention, a conductor rail 3 is also attached to the bottom section 10 of the support rail 1 . The current conducting rail 3 has webs that extend vertically and are spaced apart in the transverse direction Y, which form channels in between, with conductor wires (not shown here) being arranged in the channels, which are held on the current conducting rail 3 by recesses 310 provided in the webs 31 .

On the bottom section 22 of the assembly body 2 is in figure 1 A contact device 4 is fixed in the specified operating position, the mounting section 7 of the contact device 4 being pressed in the vertical direction Z against the bottom section 22 of the mounting body 2 . In addition to the mounting section 7 , the contact device 4 has a contact section 5 which is offset along the vertical direction Z with respect to the mounting section 7 . How out figure 1 shows, the contact section 5 of the contact device 4 webs 51, which are arranged in the operating position in the channels of the current-conducting rail 3 and press against conductor wires of the current-conducting rail 3, which are arranged in the channels and are held on the webs 31. The figure does not show the electrical contact elements which are provided on the webs 51 of the contact section 5 and which press against the conductor wires of the current-conducting rail 3 in the operating position.

The contacting of the contact device 4 to the conductor rail 3 is thus explained. In addition, longitudinal conductors are provided in the system according to the invention in the embodiment shown in the figures, in particular for supplying functional elements of the system that are spaced apart from the contact device 4 in the longitudinal direction. In the embodiment according to the invention, these conductors or lines run in holding sections or recesses which are formed by holding brackets on the contact device 4 . In the representation of figure 1 of the conductor holding device produced integrally with the contact section 5, a holding bracket 58b can be seen, which fixes a holding section 59b which is closed in the YZ plane except for a vertical gap, with the holding bracket 58b having the vertical gap 62b already mentioned. For this purpose, the retaining clip 58b comprises two spaced vertical arm sections 61a, b, which comprise a predetermined spacing in the vertical direction to provide the said gap 62b. In the embodiment described, the retaining bracket 58a is formed integrally with the contact section or the contact part 5 as an injection molded part, with a small longitudinal extent of the retaining bracket, for example a value between 1.5 mm and 3 mm, see FIG figure 2 , Allows an elastic deflection of the vertical arm sections in the longitudinal direction. This applies in particular to the Vertical arm section 61a due to its vertical extent, which is greater than the second vertical arm section 61b.

The relative arrangement of the contact section 5, the mounting section 7 of the contact device 4 and the mounting body 2 is shown in the perspective view according to FIG figure 2 out. The contact section 5 has a section 53 with which it rests on a section 76 of the mounting body 7 and is held pressed against this section 76 . From the synopsis of Figure 1 and 2 It can also be seen that the mounting body 7 has a spring device 71 which forms a scratching lug 730 at one transverse end, which in the operating position presses from below against the projection 210 of a side wall section 21 of the mounting body 2 assigned to the respective scratching lug 730 and in the process presses a support section 75 of the mounting section 7 against the bottom section 22 of the mounting body 2. It should be noted that in the schematic representations of the principles, the spring device 71 is shown in its undeflected rest position, which is purely due to the representation. On the other hand, in the operating position, the scratching lug 730 does not extend into the side section 21, as shown in the figures, but rests against the projection 210 of the side wall section 21 from below and thereby presses the support section 75 of the mounting section 7 against the bottom section 22 of the mounting body 2.

figure 2 shows in a perspective oblique view the design of the conductor holding device on the contact section or the contact part 5 for accommodating lines running in the longitudinal direction X, such as cables etc., these lines not being shown in the figure. The contact section 5 has flanges 57a, b on its longitudinal ends or end faces and 57c,d extending transversely outwardly from the respective sidewall 56a,b. In the embodiment shown in the figures, the flanges 57a, c extending from the side wall 56a are formed with a recess that acts as a holding section 59a, b, so that a respective holding bracket 58a, b is formed, which has two vertical arm sections 60a, b and 61a, b, which are spaced apart from one another at a predetermined vertical distance, resulting in the gap 62a, b that can be seen in the figures in the vertical direction. It can be seen that the retaining brackets 58a, b, which are spaced apart in the longitudinal direction and provided with a predetermined longitudinal extent, are designed in such a way that the two gaps 62a, b are offset from one another in the vertical direction. This offset ensures that when the assembly body 2, on which the contact device as in figure 2 is placed and fastened, with the support rail 1 in the vertical direction relative thereto, one of the transverse projections 11a, b extending over the longitudinal extension of the support rail 1 is prevented from engaging with the gaps 62a, b of the retaining brackets 58a, b. In the embodiment described, the end faces of the holding arm sections 60a, b and 61a, b, which are opposite one another and define the respective gap 62a, b, are formed at an angle relative to the XY plane. In addition, the respective gap 62a, b in the longitudinal direction has an extension of <3 mm, in particular <2 mm, so that when the holding arms are in the rest position, conductors or cables held by them cannot accidentally fall out of the respective holding area, especially when the operating position of all components is adjusted.

In the Figures 3 and 4 are the two components, ie the Contact section 5 and the mounting section 7 of the contact device of the system according to the invention are shown in a respective perspective view. In the present exemplary embodiment, the mounting section 7 is designed as a component which is produced from sheet metal by sheet metal forming. The assembly section 7 has a sheet metal section 73 formed by the deformation, which is designed as a projection extending inwards in the transverse direction. In contrast, the contact device 5 has a complementary section formed by projections 52 which can be brought into engagement with the sheet metal section 73 . In the specified embodiment, the contact section 5 has an injection-molded body, in which both the webs 51 and the projections 52, which form the opposite section to the sheet metal section 73 described, are formed as part of the injection-molded body. The contact section 5 and the mounting section 7 of the contact device can be fixed to one another so that they cannot be lost by attaching the contact section 5 relative to the mounting section 7 in such a way that the formed sheet metal section 73 of the mounting body 7 encompasses the projections 52 and the contact section 5 with its section 53 is pressed against the corresponding section 76 of the mounting body 7. The mounting section 7 has stops 74 that define a longitudinal area within which the contact section 5 can be displaced in a mounting position relative to the mounting section 7 along the longitudinal direction X. In the operating position of the mounting part and the contact part of the contact device, this displaceability in the longitudinal direction is blocked.

Out of figure 4 In particular, the offset of the gaps 62a, b of the two holding brackets 58a, b arranged offset in the longitudinal direction X is indicated. In the XZ plane has a Connecting line V of the gaps 62a, 62b to the longitudinal direction X at an angle α of about 13 °. The figure also shows a movement path S, oriented parallel to the longitudinal direction X, of a robot blade for inserting a cable or conductor that extends in the longitudinal direction and is accommodated in the two holding sections 59a, b. The blade noticeably hits against the two vertical arm sections 60a, 61a with the larger vertical extensions, which are elastically deflected in the longitudinal direction when the robot blade strikes and snap back into their operating position after the blade has passed through.
