    LIGHT MODULE FOR A MOTOR VEHICLE HEADLAMP
    The invention relates to a light module for a motor vehicle headlamp, wherein the light module comprises at least one light source, at least one light shaping unit, at least one drive means, by which the light module is adjustable, and a cable harness for driving and / or powering the light module to the light module a plug connection to the light module is connected, wherein the plug connection has a plug and a plug counterpart, via the plug and the cable harness, the light module and the light sources therein and the at least one drive means, preferably stepper motor, supplied with power.
    In a light module of a cornering headlight, for example, two drive means may be provided, wherein a drive means for pivoting the light module or the at least one light-shaping unit and the other drive means is used for headlight range control.
    Since now increasingly LED modules are used as light sources in motor vehicle headlights, as well as cornering headlights, and for the operation of the LED modules, a higher number of individual cables in the harness are necessary, the entire cable harness tends to increased stiffness at minus temperatures. As a result, the motor arranged on the light module and used as drive means requires more force in order to move the light module forwards or backwards, for example in the course of headlight range control, whereby step losses on the engine can occur more frequently.
    Furthermore, in constant light module movements, such as headlight range control, widening of the plug contacts of the individual cables of the cable harness to the plug, which leads to frequent loose contacts on the plug, cable breaks are not excluded.
    In known solutions of the prior art, inter alia, significant cable excess lengths are used, whereby the cable sheath be chafed at Verschwenkungen or other movements of the light module to the surrounding components. To prevent such chafing, the individual cables or the
    Wiring harness provided with an additional sheath, such as silicone, with a risk of outgassing exists.
    It is therefore an object of the invention to provide an improved light module to avoid the above-mentioned disadvantages and other limitations of the prior art.
    This object is achieved in that the light module at least one
    Fixing device for the wire harness has to fix this wire harness punctually and / or in sections, wherein the fixing device at least one
    Coupling element and at least one arranged on the light module
    Counter coupling element, wherein the at least one coupling element has at least one holding means for the cable harness, which is adapted to the cable harness at the position at which the at least one retaining means on the
    Wiring harness is arranged to fix relative to the at least one coupling element.
    The terms "fixed" or "fixation" are also minimal for the skilled person
    Movements of the object to be fixed are included, so that not exclusively an explicitly rigid fixation is meant. This is also true for terms like "motion-proof" that include an analogous definition.
    In the above definition, for example, a cable clasped by a cable tie and thereby fixed cable, which is nevertheless movable or rotatable with sufficient force.
    The cable harness may include one or more cables.
    It can also be provided two or more cable strands.
    The light-shaping unit may, for example, a reflector, a lens and / or any
    Be intentional optics, which is adapted to light the at least one light source in his
    Intensity, direction and / or other characteristics to change or shape. Moreover, as the light source, for example, a laser, a discharge lamp or an LED can be used, wherein in the case of one LED, a plurality of light-emitting diodes can be included.
    The light module can be set up to generate at least one illumination function and / or signaling function, for example curve light, daytime running light and / or low beam light.
    The wiring harness can be substantially fixed or at least limited in its movement by, for example, a cable duct, which is usually used for laying the wiring harness in a motor vehicle headlight, by designating the beginning or end region of the cable duct as a mounting or fixing point can - for the following explanation also point B called. Another fixation or support point forms the plug connection of the plug with the plug counterpart - for the following explanation also called point A - which is usually arranged on the light module itself and moves equally with a movement of the light module.
    Between these two positions or points A and B of the cable harness is in the context of the length between these points in its movement substantially free and unrestricted, so that the wire harness in a relative movement of the connector (point A), for example, by a movement of the light module or the drive means is caused to bend or buckle in the direction of support point of the cable channel (point B), as long as the direct connection in the sense of the shortest possible distance between the fixing points A and B is shorter than the length of the harness between these fixing points A and B.
    In a relative movement of the connector (point A) in the opposite direction, however, tightens the harness, wherein the movement is limited by the length of the harness between the two mounting or fixing points A and B.
    In any type of movement from point A relative to point B, the area of the wire harness that immediately adjoins the plug also moves, causing it, as in the
    Description of the introduction mentions, inter alia, widening of the plug contacts of the individual cables of the cable harness to the plug experiences, which is undesirable.
    In order to avoid such movement, the cable harness is fixed at a further point C between the aforementioned fixing points A and B, this further fixing point C being coupled in relative movements of points A and B to the movement of point A, i. that point C is arranged immovably and / or rotationally fixed with respect to point A. The essentially free in the movement of the harness is now limited to the length of the harness between the points B and C, whereby a strain relief of the harness and especially the connector (point A) is possible.
    It should be noted that the fixation or support point B is not limited to the beginning or end portion of a cable channel, but rather is the point or point at which the wire harness along the harness - starting at the connector - to first time a fixation or holder with respect to a relative movement of the connector (point A) learns.
    The plug-in connection (point A) is preferably located on the at least one drive means, which is moved along with the support frame and the light-shaping unit in particular during a movement for light-weight control. As a rule, such a movement is essentially a movement in or against the light exit direction of the at least one light-shaping unit.
    It should be noted that mentioned in the prior art fixations of
    Wiring harness on a motor vehicle headlight housing not the desired strain relief of the connector or the area of the cable harness, which connects directly to the plug, cause, as the motor vehicle headlight housing usually forms an inertial system with respect to the light module and a rule
    Fixation point of the harness to the housing - in the sense of the above-described point C - the requirements described above with respect to the point A is not met.
    Rather, the partial fixation of the cable harness forms on the
    Motor vehicle headlight housing the analogue to the above-mentioned cable channel.
    As the wiring harness, for example, in a cable channel or on a
    Motor vehicle headlight housing is fixed in sections, this can be fixed
    Do not move the section of the wiring harness equally when moving the rest of the light module.
    Advantageously, it can be provided that the coupling connection between the at least one coupling element and the at least one counter-coupling element is detachable.
    The connection between the coupling element and the counter-coupling element may be exclusively a mechanical connection.
    In a practical embodiment of the invention, the at least one
    Holding means may be formed as a cable tie.
    Since the Kabelstrangummantelung is usually not overly sensitive to tensile and / or compressive stress, the use of a cable tie is optimal, on the one hand the harness at the position at which the cable tie is arranged on the harness, immobile or substantially immobile and / or rotationally fixed on the other hand to keep costs low.
    It can be provided that the fixing device for fixing the
    Coupling connection between the at least one coupling element and the at least one counter-coupling element has a fastening means, such as screw.
    In an expedient embodiment of the invention, the counter-coupling element can be arranged on the at least one drive means.
    The at least one drive means may, for example, in the course of a movement of the
    Moving light module for headlight range control alike, the above requirements for strain relief of the connector or the range of
    Wiring harness, which connects directly to the plug, are met.
    It may be advantageous if the counter-coupling element is firmly or non-detachably connected to the drive means.
    It can be advantageous if the element provided for use as a counter-coupling element is already part of the at least one drive means, whereby costs can be considerably reduced and a logistical effort can be reduced.
    Advantageously, the counter-coupling element can be designed as a sheet metal tongue.
    However, this does not mean a restriction to a specific material, but rather a part protruding from the at least one drive means, which is suitable for acting as a counter-coupling element. Moreover, as a counter-coupling element, each component, which is already arranged for example on the drive means and was originally intended for a different function, act.
    Thus, the metal tongue of the drive means may initially have served as electrical ground or for heat dissipation.
    It may be favorable if the coupling element is designed as a cable lug in order to couple to the mating coupling element formed as a metal tongue.
    In general, a cable lug allows electrical connection of cables or strands by screwing or plugging, usually a cable end is arranged and pressed in the cable lug. Possible embodiments are flat plug cable lugs, flat plug sleeves, ring-shaped cable lugs or forked lugs, wherein ring-shaped lugs and GabelformKabelschuhe are usually fixed by a screw with its respective counterpart.
    Commonly used terms in the trade for this type of connectors are so-called faston connectors, jacks and flat plugs, which can be designed with and without insulation.
    These standardized cable lugs represent a cost-effective design, come in different sizes and allow easy separation of the mechanical or electrical connection for service purposes.
    It can be provided that the at least one coupling element has exactly one holding means.
    The invention will be explained in more detail by way of example with reference to drawings. Show here
    1 shows an exemplary light module with a fixing device,
    FIG. 2 is a more detailed view of the light module of FIG. 1. FIG.
    3 is a side view of the top of parts of the light module of Fig. 1 and 2,
    4 is a view of the drive means with a counter-coupling element from above,
    5 shows an exemplary coupling element with a holding means,
    Fig. 6 is a detail view of the fixing device of FIGS. 1, 2 and 3, and
    Fig. 7, 8 and 9 representations of exemplary coupling elements.
    1 shows an exemplary light module 100 with a support frame 120, a light-shaping unit 110, which is designed as a lens, a drive means 500, by which the light module 100 is at least partially driven, and one for driving and / or powering the light module 100 to the Light module leading cable harness 200, wherein the light module has a fixing unit 400 to fix the wire harness 200 selectively or in sections.
    At the end of the cable harness 200, a plug 310 is arranged, which is connected to the drive means 500 and thereby to the light module 100 by means of a plug connection 300 with a plug mating piece 320 which is arranged on the drive means 500, as shown in FIG.
    The light module 100 is adapted to movements in or against a desired
    Light exit direction, which is exemplified in FIGS. 1, 2 and 3 shown as an arrow X to perform, for example, in a headlight range control.
    In the course of such a movement moves due to the arrangement of
    Connector 300 this same with, whereby the wiring harness also in
    Movement is offset.
    In order to be able to counteract cable breaks or other disadvantages that may arise as a result of an uncontrolled movement of a cable strand, the cable strand 200 is laid and fixed at least in sections in a cable channel 210 which has an initial or end region 211. The cable channel 210 is opposite to a movement of the light module at rest and a laying or fixing of the harness 200 in the cable channel 210 is equal to a fixation on a motor vehicle headlight housing in which exemplary light modules 100 may be installed, but not shown in the figures.
    When the light module 100 moves in the exemplary light exit direction X, the cable strand 200 laid or fixed in the cable channel 210 is at rest, with a section of the cable strand 200 formed by the beginning or end region 211 of the cable channel and the plug connection 300 joining a movement of the light module 100 can continue to bend or buckle.
    Any relative movement of the light module 100 relative to the cable channel 210 will set this portion of the wire harness 200 in motion, thereby also moving the portion of the wire harness 200 immediately adjacent to the plug 310, which may result in tensile stresses in that sensitive area.
    The fixing unit 400 comprises a coupling element 410 and a
    Counter coupling element 420, wherein the coupling element 410 has a holding means 411, which is adapted to the wire harness 200 at the position at which the
    Holding means 411 is disposed on the wire harness 200, with respect to the
    Clutch element 410 motion-resistant or substantially resistant to movement.
    3 shows, inter alia, an enlarged view of the fixing device 400, wherein the holding means 411 holds the wire harness 200 at a position of the portion formed by the leading end portion 211 of the cable duct and the connector 300.
    By coupling the coupling element 410 with the mating coupling element 420, which is arranged on the drive means 500 as shown in the figures, the previously movable section of the cable strand 200 between the beginning or end region 211 of the cable channel and the connector 300 is shortened to the length , which is given by the beginning or end portion 211 of the cable channel and the position of the fixing device 400, ie that upon movement of the light module 100, the region of the cable harness 200 which directly adjoins the plug 310 undergoes strain relief.
    The counter-coupling element 420 is designed in the example shown in the figures as a sheet metal tongue and as part of the drive means 500 fixedly connected thereto, wherein the coupling element 410 is formed in the example shown in the figures as a flat plug cable lug.
    Thus, Fig. 7 shows a more detailed view of the coupling element 410, which as a blade receptacle with a usually provided for cable ends pressing or
    Crimp cable lug, in which usually a cable end can be arranged and then pressed with a suitable crimping pliers - in the further course called cable area 412 - is formed.
    8 shows another example of a tab receptacle 410 having a cable portion 412 provided with insulation, the cable portion having a through opening for passing and placing the support means 411 therein.
    FIG. 9 shows a further example of a cable lug 410, which is designed as a flat plug cable lug.
    Both for the coupling element 410 and for the counter-coupling element 420 other alternatives than the examples shown in the figures are possible.
    Thus, it can be provided that the cable region 412, in contrast to the examples shown in the figures, is not arranged as an extension of the blade receptacle or blade terminal in the respective plug-in direction, but for example at a 90 degree angle thereto.
    Since the Kabelstrangummantelung is usually not overly sensitive to tensile and / or compressive stress, the support means 411 is designed in the embodiment shown as a cable tie, as shown in Fig. 1, 2, 3, 5 and 6.
    For this purpose, the cable tie 411 is arranged in the crimp lug of the tab receptacle 410, i. in the cable portion 412 of the blade receptacle, wherein the crimp lug is then pressed so that the cable tie located therein is enclosed.
    To fix the mechanical connection between the coupling element 410 and the mating coupling element 420, which can be made detachable, a fastening means, for example a screw, can be provided.
    Further possible embodiments may also have more than one fixing device 400 with two or more holding means 411 per coupling element 410.
