The invention relates to a cable duct for holding at least one cable, comprising a cable guiding portion configured to guide the at least one cable in a determined position.

The invention also relates to a vehicle headlamp with at least one cable duct according to the invention.

In current vehicle headlamps a cable duct for holding or guiding cables of a control unit and the control unit itself are mounted and assembled separately into a housing of the vehicle headlamp. This has the effect that an assembly of both parts is difficult due to the restriction of space in a housing of a vehicle headlamp. Also, during a service of a vehicle headlamp, an additional part is necessary for fixation of the control unit.

This leads to a significant effort with regard to the assembling of the cable duct and the control unit in a desired position in a vehicle headlamp.

It is an object of the invention to provide an enhanced cable duct.

To achieve this object, the cable guiding portion comprises a support portion with at least one first second engaging element, wherein the cable duct comprises a foldable holder for holding a housing of a control unit, which holder is pivotably connected to the cable guiding portion, wherein the holder comprises at least one second engaging element, wherein the holder can be brought into an end position on the support portion by folding the holder towards the support portion, such that the at least one first engaging element engages with the at least one second engaging element.

This allows the possibility to easy exchange the control unit during service in the housing, allows better balance for assembly operations, allows more flexibility of spacing of the control unit and allows easier assembly outside of the housing.

It should be noted, that apart from a housing of a control unit, the holder is also suitable to hold a PCB (printed circuit board), module, data bus or any electronic element. A d va n ta geo u s 1 y, the at least one first engaging element is built as a latching-element and the at least one second engaging element is built as a counter latching-element.

Advantageously, the at least one first engaging element is built as a detent lug and the at least one second engaging element is built as a rigid leg, wherein the rigid led snaps in the detent lug, when the holder is in the end position.

Advantageously, the holder comprises at least two second engaging elements, preferably exactly two second engaging elements.

Advantageously, the support portion comprises at least two first engaging elements, preferably exactly two first engaging elements.

Advantageously, the support portion comprises at least one protrusion configured to limit the folding of the holder towards the support portion, wherein the holder abuts on the at least one protrusion in the end position of the holder.

This has the advantage, that the holder cannot be folded beyond the desired end position. This also prevents, that the holder is shaking during naturally occurring vibrations of the vehicle headlamp or vehicle, in which the vehicle headlamp and the cable duct is installed.

Advantageously, the at least one second engaging element of the holder abuts on the at least one protrusion.

Advantageously, the support portion comprises at least two protrusions, preferably exactly two protrusions.

Advantageously, the holder is connected with the cable guiding portion by means of a hinge film.

Advantageously, the holder is connected with the cable guiding portion by means of a rotary hinge.

Advantageously, the cable duct is being made of an integral piece of material. The term "integral piece" can also be understood as "monolithic". Advantageously, the cable duct is made of one material.

Advantageously, the cable duct is made in a molding process.

The object of the invention is also be achieved by a vehicle headlamp with at least one cable duct.

In the following, in order to further demonstrate the present invention, illustrative and non-restrictive embodiments are discussed, as shown in the drawings, which show:

Fig. 1 an example of a cable duct with a support portion comprising two first engaging elements, and a holder comprising two second engaging elements,

Fig. 2 a detailed view of the first and second engaging elements of the support portion and the holder,

Fig. 3 the cable duct of Fig. 1, wherein the holder is in an end position,

Fig. 4 a detailed view of the end position of the holder, wherein the second engaging elements engage with the first engaging elements.

Fig. 1 shows a cable duct 10 for a vehicle headlamp and for holding at least one cable, wherein the cable duct 10 comprises a cable guiding portion 100 configured to guide the at least one cable in a determined position.

Further, the cable guiding portion 100 comprises a support portion 110 with two first engaging elements 110a, wherein the cable duct 10 also comprises a foldable holder 200 for holding a housing of a control unit, which holder 200 is pivotably connected to the cable guiding portion 100 wherein the holder 200 comprises two second engaging elements 210a, each of which is assigned to one first engaging element 110a of the support portion 110. In the shown example, the two first engaging elements 110a are built as a detent lug and two second engaging elements 210a are built as a rigid leg, which can be seen in more detail in Fig. 2.

The holder 200 is connected with the cable duct 10, in particular with the support portion 110 of the cable duct 10, by means of a hinge film 220, wherein the cable duct 10 is built monolithic and is made of an integral piece of material in a moulding process. The holder 200 can be brought into an end position PI on the support portion 110 by folding the holder 200 towards the support portion 110, such that the first engaging elements 110a engages with the at least one second engaging element 210a to secure the holder in the end position PI, in particular the second engaging elements 210a formed as rigid legs snap in the first engaging elements 110a formed as detent lugs, when the holder 200 is in the end position PI, which can be seen in Fig. 3 and more detailed in Fig. 4.

In order to limit the folding of the holder 200 towards the support portion 110, the support portion 110 comprises two protrusions 120, wherein the holder 200, in particular the second engaging elements 210a, abuts on the protrusions 120 in the end position PI, which can be clearly seen in Fig. 4, wherein Fig. 4 also shows a mounted housing of a control unit 300 on the holder 200.
