Description

Title of the invention: SYSTEM FOR MOUNTING AN ELECTRICAL CABLE UNDER A MOTOR VEHICLE BODY

[0001] The invention relates to a system for mounting an electrical cable under a motor vehicle body and a flange for such a system.

[0002] It is known to implement a system for mounting an electrical cable under the body of a motor vehicle, said system comprising: - on the one hand, a temporary positioning platform for elements intended to be mounted under said crate by moving said platform against said crate, said platform having a receiving face for said elements, said platform being provided with a pair of rods projecting from said face, - on the other hand, a flange made of molded plastic material, said flange being provided with two receiving holes for each of said rods in order to index the position of said flange on said plate, said flange being further provided with a channel, intended to receive at least one electrical cable, and at least one mounting hole intended to receive a screw from said box for the purpose of fixing said flange under said box by a nut.

[0003] The use of such a platform is known to allow the mounting of various elements - such as a running gear, an engine, a battery, an electrical cable, etc. - under a motor vehicle body.

[0004] The various elements are positioned on the plate and locked in nominal position by indexing means such as rods from said plate.

[0005] The platform is then moved against the case to allow the various elements to be positioned on said case and fixed.

[0006] The heaviest elements are generally fixed by screwing which is done automatically while the platform is still applied against the case.

[0007] As for the lighter elements, they are generally held on the case by means of temporary holding, in particular by interlocking, then fixed by manual screwing once the tray has been moved away from said case.

[0008] In the case of a lightweight element such as an electrical cable fixing flange, it is known to mount said flange with said cable fixed to it.

[0009] Since the cable generally has low flexibility, it may be difficult to keep the clamp in place on the plate, as the cable may exert a force tending to move it out of its nominal position.

[0010] The invention aims to provide an arrangement to overcome this in- convenient.

[0011] To this end, the invention proposes a system for mounting an electrical cable under the body of a motor vehicle, said system comprising: - on the one hand, a temporary positioning platform for elements intended to be mounted under said crate by moving said platform against said crate, said platform having a receiving face for said elements, said platform being provided with a pair of rods projecting from said face, - on the other hand, a flange made of molded plastic material, said flange being provided with two receiving holes for each of said rods in order to index the position of said flange on said plate, said flange being further provided with a channel, intended to receive at least one electrical cable, and at least one mounting hole intended to receive a screw from said box for the purpose of fixing said flange under said box by a nut, said receiving orifices being provided with deformable molded slats, said slats projecting radially into said receiving orifices so as to allow a tight hold of said rods in said receiving orifices to lock the position of said flange on said plate.

[0012] It is specified here that, throughout the description, the terms "axially" and "Radially" is taken in reference to the extension axis of a rod.

[0013] With the proposed arrangement, as explained above, the slats projecting radially towards the inside of the receiving orifices allow a tight hold of the rods in said receiving orifices to lock the position of the flange on the plate.

[0014] In addition, providing two receiving ports, each cooperating with a rod, makes it possible to lock the flange against rotation on the plate.

[0015] According to one embodiment, a mounting hole has an internal frustoconical shape intended to guide the insertion of the screw from the body during the mounting of the flange under said body.

[0016] According to one embodiment, the flange is provided with two mounting holes intended to receive each a screw from the casing, which improves the robustness of the fixing of said flange.

[0017] According to one embodiment, the system further comprises at least one clamp surrounding the cable tray in order to secure a cable in said cable tray.

[0018] According to one embodiment, a rod is mounted on the plate in an axially retractable manner, so as to allow its removal from the receiving orifice after insertion of the screw into the mounting orifice.

[0019] This avoids the risk of the flange with the plate coming loose from the housing if the nut is tightened later, the mounting hole being otherwise dimensioned to allow a tight contact of the screw in said mounting hole, and thus ensure that said flange is held on said case while awaiting the screwing of the nut.

[0020] The invention also relates to a flange of such a system, said flange being made of molded plastic material, said flange being provided with two receiving orifices intended to receive indexing rods for its position, said flange being further provided with a channel, intended to receive at least one electrical cable, and at least one mounting orifice intended to receive a screw from said casing, said receiving orifices being provided with deformable molded strips, said strips projecting radially towards the inside of said receiving orifices in order to allow a tight hold of said rods in said receiving orifices.

[0021] The invention will be further detailed by describing non-limiting embodiments, and based on the accompanying figures illustrating variants of the invention, in which: [Fig. 1] is a partial schematic cross-sectional representation of a mounting system and part of a motor vehicle body according to one embodiment, the platform being positioned against said body to ensure the mounting of the flange, [Fig.2] is a schematic perspective representation of a flange according to one embodiment.

[0022] A system 1 for mounting an electrical cable 2 under a motor vehicle body is now described with reference to the figures, said system comprising: - on the one hand, a platform 3 for the temporary positioning of elements intended to be mounted under said body by moving said platform against said body, said platform having a receiving face 4 for said elements, said platform being provided with a pair of rods 5 (only one being shown in [Fig. 1]) projecting - here perpendicularly - from said face, - on the other hand, a flange 6 made of molded plastic material - for example, of reinforced polyamide - said flange being provided with two receiving holes 7 for each of said rods in order to index the position of said flange on said plate, said flange being further provided with a channel 8, intended to receive at least one electrical cable 2, and at least one mounting hole 9 intended to receive a screw 10 from said box for the purpose of fixing said flange under said box by a nut, not shown, said receiving orifices being provided with deformable molded slats 11, said slats projecting radially into said receiving orifices so as to allow a tight hold of said rods in said receiving orifices to lock the position of said flange on said plate.

[0023] According to the embodiment shown, a mounting hole 9 has an internal shape truncated cone intended to guide the insertion of the screw 10 from the case during the assembly of the flange 6 under said case.

[0024] According to the embodiment shown in [Fig.2], the flange 6 is provided with two mounting holes 9 intended to receive each one a screw 10 from the casing.

[0025] According to the embodiment shown, the system 1 further includes at least one clamping collar 12 surrounding the chute 8 in order to secure a cable 2 in said chute.

[0026] According to an embodiment not illustrated, a rod 5 is mounted on the plate 3 in an axially retractable manner, so as to allow its removal from the receiving orifice 7 after insertion of the screw 10 into the mounting orifice 9.

[0027] Finally, a flange 6 of such a system 1 is described, said flange being made of molded plastic material, said flange being provided with two receiving orifices 7 intended to receive indexing rods 5 for its position, said flange being further provided with a channel 8, intended to receive at least one electrical cable 2, and at least one mounting orifice 9 intended to receive a screw 10 from said casing, said receiving orifices being provided with deformable molded strips 11, said strips projecting radially towards the inside of said receiving orifices in order to allow a tight hold of said rods in said receiving orifices.
