Description

Title of the invention: Clip for securing high-voltage power cables comprising a movable part

[0001] The invention relates to means for holding high voltage power cables, in particular high voltage power cables for batteries of electric or hybrid motor vehicles.

[0002] Prior art patent application EP1740868 is known, describing a one-piece spacer designed to hold a coaxial aircraft fuel line. This spacer comprises a pipe clamping structure, at least one spacer element attached to the clamping structure, and at least one closure integrated into the spacer element for adjusting the spacer's diameter. The closure includes a pin comprising a hook and an eyelet comprising a complementary hook. The hook and the complementary hook, when assembled together, function as a cable clamp. However, a drawback remains. The clamping structure has a fixed length which, when closed, has a substantially constant inner diameter.The same clamping structure can therefore be used for several pipes of the same or nearly the same diameter, but if you want to change the pipe to one of a smaller or larger diameter, then you need to change the spacer. This represents an additional cost, as well as more assembly time.

[0003] The objective of the present invention is to remedy these drawbacks and to provide a unique clip that can hold high-voltage power supply bundles of a battery of any diameter.

[0004] To achieve this objective, the invention provides a clip for securing a first high-voltage power supply bundle and a second high-voltage power supply bundle of a battery in an electric or hybrid motor vehicle, said clip having a substantially parallelepiped shape, said clip having a length along a first longitudinal axis, a width along a second transverse axis orthogonal to the first axis, and a height along a third vertical axis orthogonal to the first and second axes, notable in that said clip comprises a fixed part and a movable part along the third axis, said fixed part having a lower face along the third axis comprising a first upper edge and a second upper edge, the first upper edge being adjacent to the second upper edge, said movable part comprising an upper face along the third axis comprising a first lower rim and a second lower rim, the first lower rim being adjacent to the second lower rim, the first upper rim being positioned opposite the first lower rim, the second upper rim being positioned opposite the second lower rim, said clip comprising two lateral faces positioned opposite each other, each lateral face comprising a guide slide so as to bring said moving part closer to or further from said fixed part, said clip being capable of having two configurations such as: - an open configuration in which said lower face of the fixed part is positioned at a non-zero distance from said upper face of the moving part; - a closed configuration in which said lower face of the fixed part is positioned at a zero distance from said upper face of the moving part, the first upper rim and the first lower rim defining a first opening, the second upper rim and the second lower rim defining a second opening, said first opening being configured to accommodate the first high-voltage supply beam, said second opening being configured to accommodate the second high-voltage supply beam.

[0005] Thanks to the invention, it is no longer necessary to replace the clip when replacing high-voltage power supply harnesses with other high-voltage power supply harnesses of a different diameter.

[0006] Preferably, said fixed part has a first vertical bore about the third axis, said movable part has a second vertical bore about the third axis, the first bore being positioned opposite the second bore so that the first bore and the second bore form a single bore when said clip is in the closed configuration, said single bore being configured to accommodate a fixing screw.

[0007] Thus, the clip can be fixed to a structure, for example to the protective casing of a battery.

[0008] Advantageously, said second bore is tapped.

[0009] The tapping allows the staple to be held firmly to the structure on which it is fixed.

[0010] Advantageously, each lateral face of said movable part has a clamping tooth configured to facilitate the passage of the clip from the open configuration to the closed configuration or from the closed configuration to the open configuration.

[0011] Thus, a technician can easily manipulate the clamping teeth to adjust the clamping of the power supply bundles.

[0012] Preferably, each guide slide is toothed.

[0013] This allows the moving part to be fixed at the desired distance to properly maintain the high-voltage power supply beams.

[0014] Advantageously, the first upper rim, the second upper rim, the first lower rim and the second lower rim each have a V shape so that the first opening and the second opening each have a diamond shape.

[0015] Thus, the openings correctly fit the high-voltage power supply beams.

[0016] Preferably, each guide slide comprises a female dovetail and a male dovetail, said female dovetail being positioned on said fixed part, said male dovetail being positioned on said moving part, said male dovetail being inserted into the female dovetail, said male dovetail being able to slide in said female dovetail along the third axis.

[0017] Furthermore, the invention relates to an electric or hybrid motor vehicle comprising a battery including a first high-voltage power supply harness and a second high-voltage power supply harness, said battery including a protective casing, the first high-voltage power supply harness and the second high-voltage power supply harness being held together by a clip described previously, said clip being fixed to said protective casing.

[0018] Preferably, said clip is fixed to said protective housing by a fixing screw.

[0019] In this way, the clip is easily positioned opposite the high-voltage power supply beams from said battery.

[0020] 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] schematically illustrates a cross-sectional view of a clip having a closed configuration according to one embodiment of the invention; - [Fig.2] schematically illustrates, in perspective, the staple presenting a closed configuration positioned on a protective casing of a battery of an electric or hybrid motor vehicle; - [Fig.3] schematically illustrates a cross-sectional view of the staple showing an open configuration; - [Fig. 4] schematically illustrates, in perspective, the staple presenting a open configuration positioned on the battery protection casing of the electric or hybrid motor vehicle.

[0021] The present invention is a clip 100 for securing a first high-voltage power supply cable 1 and a second high-voltage power supply cable 2 of a battery in an electric or hybrid motor vehicle. Furthermore, the battery includes a protective housing 11. Figure 1 shows a cross-sectional view of said clip 100. The clip 100 has a parallelepiped or substantially parallelepiped shape, having a height along a first longitudinal axis X, a width along a second transverse axis Y orthogonal to the first X, and a height along a third vertical axis Z orthogonal to the first X and second Y axes. The clip 100 comprises a fixed portion 3 and a movable portion 4 along the third Z axis. The fixed portion 3 has a lower face along the third Z axis comprising a first upper edge and a second upper edge. The first upper edge is adjacent to the second upper edge.The movable part 4 has an upper face along the third Z-axis comprising a first lower rim and a second lower rim. The first lower rim is adjacent to the second lower rim. The first lower rim is positioned opposite the first upper rim. The second lower rim is positioned opposite the second upper rim. Furthermore, the clip 100 has two lateral faces positioned opposite each other. Each lateral face has a guide slide 5 for moving the movable part 4 along the third Z-axis to move it closer to or further from the fixed part 3. Preferably, each guide slide 5 is serrated, allowing adjustment of the distance at which the movable part 4 is fixed relative to the fixed part 3. Preferably, each guide slide 5 has a female dovetail and a male dovetail.The female dovetail is positioned on the fixed part 3. The male dovetail is positioned on the moving part 4. The male dovetail is inserted into the female dovetail such that the male dovetail can slide within the female dovetail along the third axis Z. The clip can be configured in two ways. In Figures 1 and 2, the clip is shown, respectively in cross-section and perspective, in a closed configuration. The closed configuration is characterized by the lower face of the fixed part 3 being positioned at zero distance from the upper face of the moving part 4. In other words, the lower face of the fixed part 3 is in contact with the upper face of the moving part 4.In Figures 1 and 2, the first high-voltage supply beam 1 and the second high-voltage supply beam 2 have a first diameter, the diameter of the first high-voltage supply beam 1 being equal to the diameter of the second high-voltage supply beam 2. In the closed configuration, the first upper rim and the first lower rim define a first opening 6 in which the first high-voltage supply beam 1. is suitable for insertion. The second upper rim and the second lower rim define a second opening into which the second high-voltage power supply bundle 2 is suitable for insertion. Preferably, the first upper rim, the second upper rim, the first lower rim, and the second lower rim each have a V-shape such that said first opening 6 and said second opening 7 each have a rhombus shape. In Figures 3 and 4, the clip is shown, respectively in cross-section and in perspective, in an open configuration. The open configuration is characterized by the position of the lower face of the fixed part 3 at a non-zero distance from said upper face of the moving part 4. In other words, the moving part 4 is not in contact with the fixed part 3.In Figures 3 and 4, the first high-voltage power supply bundle 1 and the second high-voltage power supply bundle 2 each have a second diameter, the second diameter being larger than the first. Despite the fact that the diameter of the high-voltage power supply bundles shown in Figures 3 and 4 is larger than the diameter of the high-voltage power supply bundles shown in Figures 1 and 2, the same clip 100 allows the high-voltage power supply bundles to be held regardless of their diameter. In each of Figures 1 to 4, the fixed part 3 has a first vertical bore 8a along the third Z-axis, and the moving part 4 has a second vertical bore 8b along the third Z-axis.The first bore 8a is positioned opposite the second bore 8b so that, when the clip 100 is in its closed configuration, the clip has a single bore formed by the first bore 8a and the second bore 8b. Preferably, a fastening screw 9 is inserted into this single bore to secure the clip 100 to the battery's protective cover 11. Optionally, the second bore 8b is tapped. The clip 100 is thus securely held to the protective cover 11 by the fastening screw 9. Preferably, each side face of the moving part 4 has a clamping tooth configured to facilitate the movement of the clip 100 from the open to the closed configuration and vice versa.Indeed, for a technician, it is enough to grasp one or each of the clamping teeth and move it vertically along the third Z axis to mount or dismount the first high-voltage power supply harness 1 and / or the second high-voltage power supply harness 2.

[0022] Furthermore, the invention relates to the electric or hybrid motor vehicle comprising the battery including the first electrical power supply harness 1 and the second high-voltage power supply harness 2 held together by the aforementioned clip 100 described above. The clip 100 is fixed to the protective housing 11, preferably by means of the fixing screw 9.
