    Vehicle headlights with a cable duct and manufacturing process therefor
    The invention relates to a vehicle headlight, which comprises a cable duct which has a predefined shape corresponding to a course within the vehicle headlight, the cable duct comprising at least two cable runs running along a longitudinal direction, each extending in the longitudinal direction between two track ends, and each cable run transversely to its longitudinal direction an essentially U-shaped cross section, which is formed by two legs and a base, the legs being connected to one another via the base and the legs each having open leg ends.
    The invention also relates to a production method for a cable duct of a vehicle headlight.
    Modern vehicle headlights increasingly contain an ever increasing number of electronic assemblies or lighting units which have to be connected to one another in order to become operational for their respective function. The lines or cable connections required to connect the components are often laid loosely within the vehicle headlight. Cable ducts for routing lines are generally known.
    A cable duct according to the prior art is a system for the laying of electrical lines. Cable ducts are often used to arrange several cables or lines in a common route. The cable duct serves to protect and mechanically relieve the lines, but also to increase operational safety by avoiding otherwise exposed lines. A cable duct is also understood here to mean a cable guide or a cable duct.
    During assembly, plastic cable ducts are often first screwed or glued to the installation site, for example a wall. In addition, rigid connecting elements and rigid corner pieces can be used to form a course for the cable routing. Then the cables are placed in the cable duct. For this purpose it is common if the cable duct is not provided with a removable cover

    P15144 is first a so-called "spring inserted into the cable duct, in order to then be able to pull the cables through, which are attached to this spring. In order to lead individual cables out of the cable harness, the cable duct must have corresponding interruptions at certain points. It is difficult to undertake the insertion process yourself
    Using a spring.
    The problem with cable ducts is also that the inserted cables lie loosely in the duct, which is undesirable, for example, in the automotive environment. It is possible to fix the cables in the cable duct with cable ties, but there are several disadvantages. This means that the connection cannot be released again without destroying it, for example in order to pull in another cable later. Furthermore, this assembly process is difficult to automate and requires a long assembly time.
    The cable bundles can also be attached by film hinges or cable clips in the form of separate components that clasp them. However, a complex coordination is necessary, which is tied to a cable configuration. Furthermore, the material must be selected accordingly, which can have an unfavorable effect on the price and also increase the complexity of the tool. Overall, this variant is susceptible to fluctuations in the series production of corresponding cable ducts, with the film hinge, for example, being able to tear off more frequently. Cable clips often require an additional assembly step.
    Another known approach includes spiral hoses for guiding one or more cables or lines. However, these have only a very low mechanical intrinsic stability, in particular in the direction of the longitudinal extent, and consequently can only protect the lines to a limited extent. They are used to hold several lines together rather than to avoid exposing lines. However, large parts of the surface of the internal cables are freely accessible and are therefore only protected to a limited extent. In the case of a spiral hose, the pulling in of the cables, in particular in the case of longer cables, is not trivial, but requires a spring or a high mechanical outlay when wrapping the cables. Cable branches from the wiring harness are difficult to implement.

    P15144
    Separate cable ducts or spiral hoses are currently hardly used in automotive engineering. Of course, parts of the body can be used to run cables in the manner of a cable duct. Separate cable ducts, that is to say those which are installed as separate components in a vehicle only for this purpose, are not very widespread, since each additional cable duct is associated with a higher weight. This is why prefabricated cable harnesses are often used. In the case of assembled cable harnesses, however, it is necessary that, for example, the electrical configuration of the
    Components in a motor vehicle is fixed and consequently a specific wiring harness is required for almost every variation in the configuration of the components. With the increasing complexity of motor vehicles, for example due to a large number of assistance systems, entertainment systems or security systems, it is often necessary to develop a large number of different wiring harnesses for a vehicle. As a result, it is necessary to develop ways to route and secure the wiring harness in the vehicle. This is so complex because the number of lines or cables that are combined in a cable harness can vary greatly and the diameter of the cable harness, through which the cross section of the cable bundle is formed, can therefore also vary widely. All of these properties can lead to higher development costs or logistics costs.
    State of the art cable ducts are often manufactured by an extruder process. Continuous, continuous profile strands are created, such as U-shaped profiles made of plastic for use as a cable duct. The advantage here is the cost-effective production of elongated products. Extrusion is a continuous process in which a continuous mass flow is passed, for example, through a nozzle and then solidified in a controlled manner on a cooling section. Variations in the geometry along the production direction can, however, only be carried out to a very limited extent and require separate operations, which leads to high production costs. However, it has been shown that cable ducts produced by the extrusion process have too few degrees of freedom in their design for applications in the automotive sector, so that in many cases such cable ducts are not suitable for applications in the automotive sector.

    It is the object of the present invention to provide a vehicle headlight with a cable duct which overcomes the disadvantages mentioned and is suitable for the automotive industry.
    The object is achieved by a vehicle headlight with a cable duct of the type mentioned at the outset, in which the at least two cable tracks can be arranged in succession in the longitudinal direction, so that they are located in an imaginary extension of the essentially U-shaped cross section in the longitudinal direction and at least apart from one another by an interruption the base are separated, as a result of which they are spaced apart from one another in the longitudinal direction with respect to the interruption, and the first cable run is connected to the second cable run at its mutually facing track ends via a bridge. The bridge can have a width transverse to the longitudinal extension of the bridge that is less than the length of the base or the length of the legs. As a result, the legs can also be partially interrupted.
    The arrangement according to the invention ensures that the assembly of cables is simplified and the retention of the cables in the cable duct is improved. In addition, interruptions in the cable duct can be used to create branches, for example by which individual cables can be led out of a cable bundle or cable harness to a device without the cable duct having to be completely interrupted and a multi-part cable duct being required.
    The inventors have also recognized that short and curved cable ducts are generally required in automobile construction, and that variations in the construction along the longitudinal extent can be used favorably for simplified assembly. Therefore, compared to conventional extrusion processes, alternative manufacturing processes are particularly well suited, such as the injection molding process or the 3D printing process. Furthermore, when using a cable duct inside a headlamp, there is no need to cover the cable duct, since in many cases the headlamp has a largely sealed housing and the cables do not have to be protected against excessive moisture and aggressive substances, such as brine, for example may be required for a cable duct that is arranged in the engine compartment of a vehicle. A cable duct according to the invention can be used to optimize it, only one

    To provide cable management with a simple installation of the cable duct, protection against contamination and mechanical forces can play a rather minor role. This can result in cost advantages.
    In a first aspect of the invention, the cable duct according to the invention is further developed in a vehicle headlight such that the bridge runs from the open leg end of one leg of the first cable run to the open leg end of the leg of the second cable run located diagonally opposite.
    It can thereby be achieved that it is possible to lay the lines around the cable duct and, if the cable duct is appropriately equipped with cables or lines, to achieve a positive connection between the cable bundle and the cable duct, which leads to a fixation of the cables within the cable duct.
    In a special variant, each cable run has an essentially U-shaped cross-section transverse to its longitudinal direction, which has a base with two base ends and a first leg with two leg ends and a second leg with two
    Leg ends is formed, wherein a leg end of the first leg is connected to a leg end of the second leg via the base ends of the base.
    In other words, the first cable run is connected to the second cable run at a respective track end via a bridge, the bridge extending from the open leg end of the first leg of the first cable run to the open leg end of the second leg of the second cable run or from the open leg end of the second leg of the first
    Cable run to the open leg end of the first leg of the second cable run.
    The vehicle headlight according to the invention with a cable duct according to the invention can be used to insert a cable, a cable harness or even a loose cable bundle into the cable duct before assembly, for example in a vehicle, and then to swing the cable bundle around the bridge or the bridge around the cable bundle can be. This rotary movement when wrapping is particularly easy to carry out. Overall, the cable harness can thus be inserted very easily into the cable duct, with the cable harness subsequently in the cable duct from

    P15144
    Bottom, the side walls and one or more bridges is surrounded and thus held within the cable duct.
    The side walls of the cable duct offer good protection, for example against mechanical, chemical or thermal influences. The bridges ensure that the wiring harness cannot fall out of the cable duct. At the same time, the inventive division of the cable duct into cable trays which are connected to one another by bridges ensures that the cable harness can be easily inserted into the cable trays and, at the same time, the cable duct including the cable harness is flexible when laid, for example, inside a vehicle.
    In a first embodiment, the vehicle headlight with the cable duct according to the invention comprises at least one further, third cable run, the cable run transverse to its longitudinal direction having an essentially U-shaped cross section, which is formed by two legs and a base, the legs being connected to one another via the base are connected and the legs each have open leg ends, whereby the third cable run can be lined up in the longitudinal direction, so that it is located in an imaginary extension with the first and second cable run and the cable runs are spaced apart in the longitudinal direction, and the second cable run with the third cable path is connected at a respective path end via a second bridge and the second cable path is connected to the third cable path at a respective path end via a second bridge which is oriented essentially parallel to the first bridge.
    In other words, the vehicle headlight with the cable duct according to the invention comprises at least one further, third cable run, the cable run transversely to its longitudinal direction having a substantially U-shaped cross section, which has a base with two track ends and a first leg with two track ends and a second leg is formed with two web ends, one web end of the first leg being connected to a web end of the second leg in each case via the web ends of the base, the third cable web being able to be lined up in the longitudinal direction, so that they are in an imaginary extension with the first and second Cable car is located and there is a distance between them
    7/40
    P15144
    Longitudinal direction, and the second cable run is connected to the third cable run at a respective track end via a second bridge, the first bridge running from the open leg end of the first leg of the first cable run to the open leg end of the second leg of the second cable run, and the second bridge from the open leg end of the second leg of the second
    Cable run to the open leg end of the first leg of the third cable run or the first bridge from the open leg end of the second leg of the first
    Cable run to the open leg end of the first leg of the second cable run, and the second bridge from the open leg end of the first leg of the second cable run to the open leg end of the second leg of the third
    Cable car.
    In this embodiment, the vehicle headlight with the cable duct according to the invention comprises at least two bridges which are arranged between three cable runs, the two bridges between the three cable runs alternating from the open one
    Leg end of the first leg of the first cable run to the open leg end of the second leg of the second cable run and from the open leg end of the first leg of the second cable run to the open leg end of the first leg of the third cable run. It can thereby be achieved that the winding of the cable harness through the cable duct or the winding of the cable duct through the cable harness does not have to take place in the same direction of rotation for each section of the cable duct. This can, of course, simplify the process of inserting the cable bundle into the cable duct.
    Alternatively, two bridges can also be arranged such that both the first bridge and the second bridge run from the open leg end of the first leg of the first cable run to the open leg end of the second leg of the second cable run, or both the first bridge and the second Bridge runs from the open leg end of the second leg of the first cable run to the open leg end of the first leg of the second cable run.

    As a result, the cable bundle can be inserted very easily, in particular in the case of short cable ducts, since the same hand movement can always take place during insertion.
    A particularly favorable embodiment is provided if the distance in the longitudinal direction of the cable runs is greater than the width of the base of at least one of the cable runs and preferably a maximum of five times as long, particularly preferably a maximum of three times as long as the width of the base of at least one of the cable runs. The spacing between two cable trays chosen according to the invention makes it particularly easy to insert a cable harness into the cable duct. It is clear that with two successive cable trays, a planned routing of the cable duct can be adapted and that the same distances do not have to be present.
    A further particularly favorable embodiment is provided if the extension in the longitudinal direction of at least one of the cable runs is at least three times, preferably at least five times as long, particularly preferably at least ten times as long as the width of the base of at least one of the cable runs. The length of one of the cable trays chosen according to the invention makes inserting a cable harness into the cable duct particularly easy. It is clear that two successive cable trays can be adapted to a planned routing of the cable duct and do not have to have the same dimensions.
    A further advantageous embodiment is provided if the legs and the base of at least one of the cable trays are of essentially the same length, since this enables the arrangement to be particularly stable. It is clear that two successive cable runs can be adapted to a planned routing of the cable duct and do not have to have the same dimensions of the respective leg and base.
    In a preferred embodiment, at least one of the cable runs in the side walls, which is formed by the legs with their extension in the longitudinal direction or in the bottom, which is formed by the base with their extension in the longitudinal direction in the respective cable run, has holes, cutouts, fastening tabs or variations in the Wall thickness. This creates a flexible installation option for plug-in or screw connections. The material and weight of the cable duct can also be reduced. It is clear that two successive cable trays
    9/40
    P15144 can be adapted to a planned routing of the cable duct and do not have to have the same side surfaces.
    In a further preferred embodiment, the bridge runs in a plane which is parallel to the plane which is formed by the base of at least one of the cable trays and their extension in the longitudinal direction. It can thereby be achieved that the cable harness is surrounded by the cable duct and the cable harness is prevented from falling out of the cable duct. It is clear that two successive cable trays can be adapted to a planned routing of the cable duct and do not have to have the same bridges.
    In another embodiment, the bridge has a width that is smaller than the base of at least one of the cable trays. This gives the cable duct a certain flexibility, which facilitates assembly along a predefined laying path, for example in a vehicle. It is clear that two successive cable trays can be adapted to a planned routing of the cable duct and do not have to have the same bridges.
    In a particularly advantageous embodiment of the cable duct, the bridge is connected to an extension of a leg, which extends in or against the longitudinal direction at least partially as a continuation of the leg, the extension of the leg beyond the end of the other leg of the same cable run at the same end of the path protrudes. This makes it possible to manufacture the cable duct in one piece by an injection molding process, no slider being required during manufacture, or a shaping without undercut is possible. As a result, the cable duct can be manufactured particularly cost-effectively.
    In a second aspect of the invention, the vehicle headlight with the cable duct according to the invention is further developed such that the cable duct comprises at least one bridge which runs from one leg of the first cable run to the leg of the second cable run located in the extension of the leg of the first cable run and at least one Cable clamp bridge runs from the open leg end of one leg of the first cable run to the open leg end of the other leg of the first cable run, and preferably runs transversely to the longitudinal direction. This can be achieved
    10/40
    P15144 that the area of the bridge that connects the first to the second cable run is used to prevent the cables or lines from falling out.
    This aspect can be further improved by the fact that the at least one
    Cable clamp bridge comprises a bridge projection and a bridge wing, which together form the cable clamp bridge, but which can be interrupted. The elastic properties of the bridge wing allow this interruption. The bridge wing is preferably longer than the bridge projection transversely to the longitudinal direction in order to improve the bendability of the bridge wing. It can thereby be achieved that cables can be inserted very easily into the cable duct by pressing the cable onto the elastic bridge wing, which yields under the contact pressure and the cable can be inserted into the cable duct. The cable duct has an interruption in the base of the cable run at the position of the cable clamping bridge, so that cables can also be inserted if there are already other cables in the cable duct, since the interruption allows the cables in the cable duct to be overpressed and cables are still inserted can, if the cable duct is almost fully populated. When fully loaded, a form fit can be achieved between the bundle of cables and the cable duct, so that the cable bundle is fixed within the cable duct. An additional fastening, for example with cable ties, is therefore no longer necessary, which simplifies assembly. An additional advantage is given by the fact that the arrangement can be produced in one piece by shaping without undercut for an injection molding process.
    Another advantageous embodiment of the invention consists in that an individually adapted cable duct according to the invention is produced by a 3D printing process. This results in a particularly cost-effective and flexible manufacturing process, especially for small quantities, as can occur with such individual cable ducts.
    This can be done in such a way that the cable duct is made from a plastic material, in particular partially or completely from at least one thermoplastic material, preferably a thermoplastic terpolymer (e.g. acrylonitrile-butadiene-styrene copolymer, ABS) or a thermoplastic elastomer, and by means of a 3D printing process
    11/40
    P15144 is and preferably different materials are used for the at least two cable trays and the at least one bridge.
    3D printing processes allow a mix of materials during manufacture. As a result, in particular the edges, that is to say the joints of the side walls and base, can be produced with a material which has increased strength. On the other hand, parts of the surfaces of the side walls or the bottom can be made from a particularly light material in order to save weight. If a bridge is made from a thermoplastic elastomer, the bridge itself has increased elasticity and further facilitates the handling of a cable duct according to the invention.
    As an alternative to the 3D printing process, the cable duct according to the invention can be produced from a plastic material, preferably a thermoplastic terpolymer, and by means of an injection molding process. As a result, the arrangement according to the invention can be produced simply and inexpensively by the advantageous shape.
    It is clear that successive cable runs in the above
    Embodiments can be combined in any way to adapt the cable duct according to the invention to a planned routing. Individual adjustment allows particularly easy handling when inserting the cable bundle into the cable duct and during assembly.
    The invention and its advantages are described in more detail below with the aid of some non-limiting exemplary embodiments, which are illustrated in the accompanying drawings. The drawings show in:

    12/40
    P15144
    Fig. 9 shows schematically a vehicle headlight according to the invention with a cable duct according to the invention.
    Exemplary embodiments of the invention will now be explained in more detail with reference to FIGS. 1 to 9. In particular, parts that are important for the invention are shown, it being clear that, for example, many other parts, not shown, can be included for assembly, which enable a sensible use, for example, in a motor vehicle, such as in particular a car or motorcycle. For the sake of clarity, some cables or lines are not shown.
    Due to the wide range of possible uses in a vehicle headlight, but also due to the many variants of vehicle headlights, the vehicle headlight itself is not shown. However, it is clear to the person skilled in the art how the cable duct in one
    Vehicle headlights can be arranged. Since the cable duct according to the invention is arranged within a vehicle headlight, it is ensured that environmental influences are significantly reduced compared to a cable duct which is arranged, for example, within the engine compartment of a motor vehicle. It is therefore possible to use inexpensive materials for the manufacture of the cable duct, as explained below. Also in the design of a cable duct within a headlight, it is not necessary, for example, to take into account the fact that liquids adhering to a cable duct that is arranged in the engine compartment of a vehicle, such as oils or operating fluids, can run out of the engine compartment to undesired locations. Therefore, it is not necessary to make a cable duct, which is arranged within a headlight thrower, for example by a cover or by a closed design, which can contribute to lower weight and lower costs.
    The exemplary embodiments in the figures shown represent cable ducts according to the invention in each case in a non-installed state, that is to say that when the cable ducts are installed, they can often be flexibly bent and are therefore variable, particularly at the points where two cable runs are connected by a bridge according to the invention can follow a definable course, for example, within an engine compartment of a vehicle.
    In principle, other shapes for cable ducts according to the invention are also conceivable, for example those with cable tracks curved in the longitudinal direction, to special ones
    13/40
    P15144
    To comply with installation regulations. In addition to other cross-sectional profiles of the cable trays, mounting points for mounting or for fixing the individual cable trays to mounting points in a vehicle are possible further designs of the cable duct according to the invention.
    1 shows a first aspect of the invention through a cable duct 1, which comprises at least two cable runs 110, 120 running along a longitudinal direction, each extending in the longitudinal direction 50 between two track ends 116, 117, 126, 127.
    Each cable track 110, 120 is transverse to its longitudinal direction by an essentially egg-shaped cross section, which is formed by two legs 111, 121, 112, 122 and a base 113, 123. The legs 111, 112, 121, 122 are connected to one another via the base 113, 123 and the legs each have open leg ends 114, 115, 124, 125.
    In this context, a line or a cable is understood to mean, for example:
    • an electrically conductive wire for conducting electrical current, • a hose or a pipe for conducting a gas or a liquid for, for example, a pneumatic or a hydraulic medium for a pressure line or a cooling medium for a cooling system, • optionally electrical, magnetic or thermal insulation material that envelops the wires, hoses or pipes, • optional electrical or magnetic shielding, • mechanical strain relief.
    A cable or line bundle can contain several of the lines or cables just mentioned.
    In this context, an essentially egg-shaped cross-section of a cable run means a shape in cross-section, the outer edge of the inner region of the cable run being occupied at least 50% and at most 90% by the cable run.
    The cable tray thus clasps the cables at least partially and holds them in a predefined location. It is not important whether the cross-section has square edges or rounded corners. Furthermore, in a further embodiment (not shown) it is the
    14/40
    P15144
    Invention possible that the cable run along its longitudinal direction, for example
    Changes in cross-section, recordings for other components such as cable clamps and the like, or openings in the side walls or in the floor, as well as a curved or according to laying regulations when installing, for example, in one
    Vehicle has the required course.
    In this context, the phrase “located in an imaginary extension refers to the determination of the respective leg of two successive cable runs in order to denote the course of the connecting bridge and not to an extension of the cable run in the geometric sense. In other words, an imaginary extension is understood to mean that the inscribed circumferences of two cable runs that follow one another in the longitudinal direction overlap at least 90%.
    The at least two cable trays 110, 120 can be strung together in the longitudinal direction 50, so that they are located in an imaginary extension of the essentially U-shaped cross section and are at a distance 119 from one another in the longitudinal direction 50.
    The first cable path 110 is connected to the second cable path 120 at its mutually facing path ends 117, 126 via a bridge 118. The bridge 118 runs from the open leg end 114, 115 of a leg 111, 112 of the first cable run 110 to the open leg end 125, 124 of the leg 122, 121 of the second cable run 120, which is located diagonally opposite.
    In this context, an obliquely opposite of two legs 111 and 122 of the two cable runs 110 and 120 which follow one another in the longitudinal direction 50 means that that leg 122 of the subsequent cable run 120, which in an imaginary extension of the longitudinal direction 50 of the other leg 112 of the preceding cable run 110 is meant by “diagonally opposite and not the leg 111 one
    Cable run 110 with the leg 121 of the second, subsequent cable run 120, which is located in an imaginary extension of the longitudinal direction 50 of the leg 111 of the preceding cable run 110.
    It is important in this context that with the location of two cable trays 110 and 120, which are located in an imaginary extension of their respective legs and bases,
    15/40
    P15144 an arrangement in the unmounted state is meant. Due to its material or its geometry, the bridge is bendable or malleable, and thus the cable duct according to the invention is very flexible in its course and can be arranged, for example, through the engine compartment or through the body of a vehicle.
    In other words, the first cable path 110 is connected to the second cable path 120 at a path end 117 and 126 via a bridge 118, the bridge 118 extending from the open leg end 114 of the first leg 111 of the first cable path 110 to the open leg end 125 of the second leg 122 of FIG second cable car 120 runs.
    Another possible embodiment can provide (not shown) that a single cable run is continued in two or more parallel cable runs and thus forms a branch of the cable duct (not shown). Accordingly, several bridges would be necessary at a branching of the cable duct to a plurality of subsequent cable runs which run in different directions and which are connected to a common previous cable run. It is advantageous if both legs of the previous cable run are used to connect the subsequent cable runs by means of two or more bridges. What has been said above applies to the course of the bridges and can be regarded as a superposition of arrangements according to the invention, which also falls within the scope of the following claims.
    In principle, the most varied branches can be designed in a variety of forms in order to implement specific routing routings for the lines, which are determined by the arrangement of the modules to be connected, as is known to the person skilled in the art.
    Overall, the cable duct 1 is therefore provided with an interface between the cable runs 110, 120, which enables the cable bundle to be wrapped around the cable run 110 once. The bundle of cables is then inserted into the subsequent cable run 120. A corresponding cable bundle is held in a form-fitting manner in the cable duct 1 by the bridge 118. The cable duct 1 can thus be installed together with the cable bundle as a preassembled module, for example in a vehicle headlight. The inherent rigidity of the cables ensures that the cables cannot detach themselves. Consequently, it is quick

    P15144 and simple assembly and disassembly of the cable bundle or cable harness can be carried out without the need for additional tools or devices.
    It is also an advantage of the invention that a cable duct 1 according to the invention can be produced by a conventional injection molding process and can be demolded in a main demolding direction, that is to say can be removed from the injection mold. It is therefore not necessary to use appropriate slides.

    P15144 one of the cable trays 110, 120, 210, 220, 310, 320, 330, 410, 420 or 430 can be of essentially the same length.
    Furthermore, for all of the embodiments shown in FIGS. 1 to 4, at least one of the cable trays 110, 120, 210, 220, 310, 320, 330, 410, 420 or 430 in the side walls 101, 102, 201, 202, 301, 302, 401, 402, which are defined by the first legs 111, 121, 211, 221, 311, 321, 331,411, 421,431 and the second legs 112,122, 212, 222, 312, 322, 332,412,422,432 with their extension in the longitudinal direction 50 or in the bottom 100, 200, 300,400, which by the base 113,123, 213, 223, 313, 323, 333,413,423,433 with its extension in the longitudinal direction 50 is formed in the respective cable run, have holes, recesses or variations in the wall thickness.
    In addition, the bridge can be used for all of the embodiments shown in FIGS. 1 to 4
    118, 218, 318, 328, 418 or 428 run in a plane which is parallel to the plane which is formed by the base 113, 123, 213, 223, 313, 323, 333, 433, 423, 433 at least one of the cable tracks and their extension in the longitudinal direction 50.
    For all of the embodiments shown in FIGS. 1 to 4, the bridge 118, 218, 318, 328,418 or 428 can have a width 103, 203,303,403 which is smaller than the base 113,123, 213,223, 313, 323, 333,413,423,433 of at least one of the cable trays. In this context, the width 103, 203, 303, 403 is defined and measured transversely to an imaginary connecting line which lies along the bridge that connects two cable runs, for example the bridge 118 connecting the cable runs 110 and 120. The width 103, 203, 303, 403 determines, among other things, the elasticity of the connection formed by the bridge 118, 218, 318, 328, 418, 428, which is relevant for easy installation along a predetermined route of the cable duct, for example within a vehicle.
    The bridge 118, 218, 318, 328, 418 or 428 can also have reinforcements in their cross-section, which are preferably arranged on the outer surface and which can provide a higher mechanical stability if required.
    In a manufacturing method for a cable duct 1, 2, 3, 4, not shown, the cable duct can be made of a plastic material, in particular partially or
    21/40
    P15144 be made entirely of at least one thermoplastic material, preferably a thermoplastic terpolymer or thermoplastic elastomer, and by means of a 3D printing process. Different materials can preferably be used for the at least two cable trays 110, 120, 210, 220, 310, 320, 330, 410, 420 or 430 and the at least one bridge 118, 218, 318, 328, 418 or 428.
    Of course, a cable duct 1, 2, 3 or 4 according to the invention can also be produced inexpensively by a conventional injection molding process, which is particularly advantageous for large quantities.
    The elasticity of the connection between two cable tracks is due to the width 103, 203, 303, 403 of the bridge 118, 218, 318, 328, 418, 428 as well as the material of the bridge
    118.218, 318, 328, 418, 428. In addition to the length of the bridge 118, 218, 318, 328,418,428, which is related to the distance 119, 219, 319, 329,419,429, the by
    Laying regulations of the cable duct 1, 2, 3,4 can be determined, the strength or height of the bridge 118, 218, 318, 328,418,428 is also relevant for the elasticity, but a larger height of the bridge 118, 218, 318, 328,418,428 can either restrict the cross-section of the cable run or increase the space required for the cable run, which is undesirable in some cases. Consequently, the strength and the elasticity of the connection, which is formed by the bridge 118, 218, 318,328,418,428, are preferably adjusted by the width 103, 203, 303,403 of the bridge 118, 218,318, 328,418,428.
    In order to increase the elasticity of the bridge, the geometric structure of the bridge can be, for example, wavy, triangular or rectangular along its extent between two or more cable runs. A “harmonic structure for a bridge is also possible.
    In Fig. 5, the cable duct 1 from Fig. 1 is shown, in which several cables 20 in the
    Cable tray 110 are inserted. After performing a winding movement through the subsequent cable run 120 around the cables 20, it is achieved that the cables 20 are then completely inserted into both cable runs 110, 120, as shown in FIG. 6. The elastic design of the bridge 118 allows the winding movement of the cable duct 1 without the cable duct 1 breaking. The cables 20 can be electrical lines, for example. The bridge 118 forms together with the cables 20 and
    22/40
    P15144
    Cable trays 110 and 120 form-fitting connection, so that it is ensured that no cables 20 fall out of the cable channel 1 by themselves.
    Otherwise, the supplementary explanations of FIGS. 1 to 4 apply.
    In a further exemplary embodiment (not shown), a wire harness according to the invention has a predefined course within a vehicle headlight. The cable or wiring harness can comprise a bundle of electrical wiring and hoses that carry an air conditioning medium such as, for example, air. The air conditioning medium can be used in an air conditioning circuit in order to cool solid sources of the vehicle headlight. Of course, it must always be ensured that the electrical cables and the hoses can be arranged side by side without adversely affecting each other.
    7 shows a second aspect of the invention as a fifth embodiment.
    A cable duct 5 comprises at least two cable tracks 510, 520 running along the direction 50, each of which extends in the direction 50 between two track ends 516, 517, 526, 527.
    Each cable path 510, 520 has an essentially egg-shaped cross section transverse to its direction of capture 50, which is formed by two legs 511, 521, 512, 522 and a base 513, 523. The legs 511, 512, 521, 522 are connected to one another via the base 513, 523 and the legs each have open leg ends 514, 515, 524, 525.
    A first cable run 510 and a second cable run 520 of the at least two cable runs 510, 520 can be lined up in succession in the catch direction 50, so that they are located in an imaginary extension of the essentially U-shaped cross section in the catch direction 50 and from one another by interrupting at least the base 513, 523 are separated, as a result of which they are at a distance 519 in the catching direction 50 with respect to the interruption. The first cable path 510 is connected to the second cable path 520 at its mutually facing path ends 517, 526 via two bridges 540 and 541.
    The two bridges 540, 541 each run from one leg 511, 512 of the first cable run 510 to the respective leg 521, 522 of the second cable run 520 located in the extension of the leg 511, 512.

    At least one cable clamping bridge 550 runs from the open leg end 514, 515 of one leg 511 of the first cable run 510 to the open leg end 525, 524 of the other leg 512 of the first cable run 510. In this example, the run
    Cable clamp bridge 550 transverse to the longitudinal direction 10.
    The cable clamp bridge 550 can comprise a bridge projection 551 and a bridge wing 552, which have a separation point 553 with one another. This allows the cable clamp bridge 550 to be opened in order to push a cable through the separation point 553. The bridge wing 552 is preferably longer than the bridge projection 551 transversely to the longitudinal direction 50. Due to the length and thickness of the bridge wing 552, the latter can have elastic properties. Cables can be inserted into the cable duct very easily after being placed on and pressed onto the separation point 553 between the bridge projection 551 and the bridge wing 552. The cable duct 5 additionally has an interruption in the base 513 of the cable path 510 at the position of the cable clamping bridge 550, so that cables can also be inserted when there are already other cables in the cable duct 5, since the interruption “overpressing the cables in the cable duct 5 (Not shown) allowed and cables can still be inserted even if the cable duct 5 is almost fully equipped. In this context, “overpressing” means pushing the cable beyond the inner volume of the cable duct. In other words, the cables are pressed into the disconnection point in the event of overpressure. This may be necessary if the cable duct is already equipped with cables and the additional cable is to be inserted past the bridge wing into the cable duct. When fully loaded, a noise connection can be achieved between a bundle of cables and the cable duct 5, so that the cable bundle is fixed within the cable duct 5. An additional fastening, for example with cable ties, is therefore no longer necessary, which simplifies assembly. An additional advantage is given by the fact that the arrangement can be produced in one piece by shaping without undercut for an injection molding process.
    Otherwise, the supplementary explanations of the Eig. 1 to 6.
    Own 8 shows a cross section of the cable duct 5 according to FIG. 7 in a sectional plane A-A, into which the cable clamping bridge 550 with the bridge projection 551 and the bridge wing 552 can be seen. In this illustration, no cable is inserted into the cable duct 5. The
    24/40
    P15144
    Bridge wing 552 is, for example, slightly bent inwards into the cable duct 5 in order to do this
    To facilitate insertion of the cables and around the 552 bridge wing when the
    Bias cable duct 5 by a bundle of cables and to support a positive connection between the bundle of cables and the cable duct 5.
    Furthermore, it can be seen that no base of a cable run is formed in the sectional plane A-A, and thus the two cable runs 510, 520 which are lined up in a row are interrupted by the distance 519. This is important in order to make the cable duct 5 in one piece by shaping without an undercut for an injection molding process.
    9 schematically shows a vehicle headlight 10 according to the invention, which comprises a headlight housing 11, at least one cable duct 1, 2, 3, 4 or 5, in which at least one cable 20 is inserted, and a plurality of electronic components 30, 31, 32, 33, 34 comprises, wherein the component 30 is, for example, an LED light source. The electronic components 41, 42, 43, 44 can be, for example, electronic circuits for controlling the light source, in particular power transistors, sensors for recording operating parameters, processor units for communication with components of vehicle electronics, heating or cooling elements, or electronic circuits for controlling pumps, for example for headlight cleaning nozzles.
    The optical function of the headlight 10 can be formed by the light source 41 and an optical reflector 12. The light 14 generated can be emitted, for example, through a transparent windscreen 13 in the direction in front of the vehicle. It is clear that other optical components can be included, such as projection lenses.
