Description

Title of the invention: Device for fixing an electrical harness housing.

[0001] The technical field relates to devices for fixing an electrical harness box, assemblies comprising such a device and an electrical harness box, as well as motor vehicles having at least one such assembly and / or at least one such device.

[0002] Automobile manufacturers are offering increasingly complex vehicles. However, despite this increasing complexity, they are constantly striving to control production costs in order to offer their customers affordable vehicles. The assembly time of a motor vehicle on its production line is an important factor, and it is necessary to reduce and / or facilitate each assembly step as much as possible.

[0003] In this context, most vehicles have at least one electrical wiring harness box located in the engine compartment. These boxes are generally difficult to attach to surrounding components. Experience shows that, in addition to the assembly difficulty, the positioning of these boxes is often inconsistent. Furthermore, attachment is usually achieved by welding, which involves assembly time and associated costs.

[0004] Thus, there is a need for a solution enabling the fixing of electrical harness boxes in a simplified manner in an engine compartment of a motor vehicle, while ensuring precise positioning of the latter.

[0005] The present invention aims to overcome the problems described above. In this technical context, one objective of the present invention is to provide a fastening device for at least one electrical harness housing, the assembly of which is facilitated and which guarantees precise positioning and orientation of the electrical harness housing.

[0006] To this end, the present invention relates to a fastening device designed to allow the fastening of at least one electrical harness box of a motor vehicle in an engine compartment of the vehicle, the device comprising a first part having a first fastening interface designed to allow the fastening of at least one harness box on the device, the device further comprising a second part having a second fastening interface designed to interact with means for fastening an engine, designed to fix the engine to an engine support of the engine compartment, the interaction allowing the removable fastening of the device to the engine support.

[0007] The invention also relates to an assembly comprising a fastening device according to the invention and at least one electrical harness housing fixed to the first part of the device.

[0008] The invention finally relates to a motor vehicle having at least one fastening device according to the invention and / or at least one assembly according to the invention, each second interface interacting with the engine fastening means.

[0009] Thus, the fastening device allows at least one wiring harness housing to be secured using the first part. Securing the assembly, or the device, is easy since it utilizes the engine mounting means, which generally protrude from the engine mount: indeed, the second part cooperates with the fastening means to ensure the secure and precise positioning of the device and therefore of each housing attached to it. Thus, the device according to the invention simplifies the mounting of wiring harness housings. Furthermore, the device according to the invention eliminates the need for welding operations usually required for securing wiring harness housings.

[0010] According to one embodiment of the fastening device, the second interface comprises a plate having an opening allowing attachment to the fastening means.

[0011] According to one possibility of the fastening device, the second fastening interface is designed to be disposed between the motor support and the motor when it is attached to the motor fastening means.

[0012] According to one embodiment of the fastening device, the first and / or second parts are shaped to at least partially follow the shape of the motor support.

[0013] Advantageously, the first interface has at least one mounting hole, each designed to allow the housing to be attached to the first part.

[0014] According to one embodiment of the fastening device, the first part comes from the material with the second part.

[0015] Advantageously, the fastening device is formed from a stamped sheet metal.

[0016] The invention will be better understood upon reading the following detailed description, given solely by way of non-limiting example and made with reference to the accompanying drawings in which:

[0017] [Fig-1] [Fig. 1] represents a perspective view of an engine compartment of a motor vehicle according to the invention, presenting a fastening device according to the invention positioned on an engine support;

[0018] [Fig.2] [Fig.2] represents a perspective view of the engine compartment of the [Fig.l], an electrical harness box being fixed to the first part of the fixing device;

[0019] In these figures, the same references are used to designate the same elements.

[0020] A fastening device 1 according to the invention, illustrated in the figures, is designed to allow the fastening of at least one electrical harness housing 2, illustrated in [Fig.2], of a motor vehicle in an engine compartment 3 of the vehicle.

[0021] The device 1 comprises a first part 4 having a first mounting interface 5 designed to allow the attachment of at least one harness housing 2 to the device 1. The first interface 5 has at least one mounting hole 6, in this case four holes 6, each designed to allow the attachment of the harness housing 2 to the first part 4, as illustrated in [Fig. 2]. The harness housing 2 is attached, for example, by screwing. In the example illustrated in [Fig. 1], the first part 4 forms a substantially flat plate.

[0022] The fastening device 1 according to the invention further comprises a second part 7 having a second fastening interface 8 designed to interact with fastening means 9 for an engine 10, illustrated in [Fig. 2], of which only one fastening tab is shown in [Fig. 2]. The fastening means 9 are designed to fix the engine 10 to an engine mount 11 in the engine compartment 3. The interaction between the second interface 8 and the fastening means 9 allows the fastening device 1 to be attached, in a removable manner, to the engine mount 11. In the example illustrated in [Fig. 2], the fastening means 9 comprise at least one stud, projecting from the engine mount 11, and a nut 12.

[0023] In the example illustrated in the figures, the first part 4 comes from the material with the second part 7. The device 1 is, for example, formed from a stamped sheet.

[0024] As illustrated in figures 1 and 2, the second interface 8 comprises a plate 13 provided with an orifice 14 allowing attachment to the fastening means 9. Thus, the orifice 14 allows the passage of the stud 12.

[0025] In the embodiment illustrated in [Fig.2], the first 4 and second 7 parts are shaped to at least partially follow the shape of the motor support 11.

[0026] Advantageously, the second fixing interface 8 is designed to be disposed between the motor support 11 and the motor 10, when it is fixed to the fixing means 9 of the motor 10. The plate 13 is therefore disposed between the fixing lug of the motor 10 and the motor support 11, when the device 1 is fixed in the motor compartment 3.

[0027] An assembly 15 according to the invention, illustrated in [Fig.2], comprises a fastening device 1 on which at least one housing 2 is fixed to the first part 4.

[0028] The fastening device 1 allows at least one electrical harness housing 2 to be fixed by means of the first part 4. The fixing of the assembly 15, or of the device 1, is easy since it takes advantage of the fastening means 9 of the motor 10, which generally protrude from the motor support 11: indeed, the second Part 8 cooperates with the fastening means 9 to ensure the precise fastening and positioning of the device 1 and therefore of each housing 2 attached to it. Thus, the device 1 according to the invention finally eliminates the need for welding operations usually required for fastening the housings 2.

[0029] The invention is not limited to the embodiment of the fastening device described above, only by way of example, but other embodiments can be designed by a person skilled in the art without departing from the scope and extent of the present invention.
