[0029] The following will clearly and completely describe the technical solutions of this application in conjunction with the embodiments. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] Water molecules in the air inside the battery pack easily condense inside the battery shell to form condensation. When the condensation accumulates more and more on the wiring harness 300 inside the battery shell, the condensation will then flow along the length direction of the wiring harness 300 to the plug-in position at the end of the wiring harness 300, causing the insulation of the plug-in to fail, posing a safety hazard.

[0031] To solve the above problems, the following Figure 1-Figure 3 , describing the wiring harness clip provided in an embodiment of the present application.

[0032] Reference Figure 1 As shown, the wiring harness clip provided in the embodiments of the present application includes a blocking portion 100 and a guide portion 200. The blocking portion 100 can be mounted on the surface of the wiring harness 300. The blocking portion 100 prevents condensation on the surface of the wiring harness 300 from continuing to flow along the length of the wiring harness 300, thereby transferring the condensation to the blocking portion 100. The guide portion 200 is connected to the blocking portion 100 and is used to guide the condensation on the blocking portion 100 along a diversion path to a predetermined location. The predetermined location refers to a location within the battery pack where there are no electrical components or a small number of electrical components and where condensation can be discharged smoothly. In some specific embodiments, the guide portion 200 is a straight guide plate, and the diversion path is consistent with the length direction of the guide portion 200. In other specific embodiments, the guide portion 200 is a curved guide plate, and the diversion path is consistent with the curvature of the guide portion 200. In still other specific embodiments, the guide portion 200 includes multiple curved sections, and the diversion path is consistent with the curvature of the guide portion 200.

[0033] By utilizing the technical solution provided by the above embodiment, by setting the blocking portion 100 and the guide portion 200, the blocking portion 100 can prevent the condensation on the surface of the wire harness 300 from continuing to flow along the length direction of the wire harness 300, so that the condensation on the surface of the wire harness 300 is transferred to the blocking portion 100, and the guide portion 200 is connected to the blocking portion 100. The guide portion 200 can make the condensation on the blocking portion 100 flow along the guide path to the position in the battery pack where there are no electrical components, thereby preventing the condensation from flowing along the length direction of the wire harness 300 to the plug-in position at the end of the wire harness 300, avoiding insulation failure, and improving safety.

[0034] Reference Figure 1 As shown, in some embodiments provided herein, a converging surface 110 is formed on the blocking portion 100, and the side of the converging surface 110 closest to the ground is connected to the guide portion 200. By providing the converging surface 110, condensation from different locations on the wiring harness 300 can be uniformly transferred to the converging surface 110. By connecting the side of the converging surface 110 closest to the ground to the guide portion 200, the condensation transferred to the converging surface 110 is uniformly converged onto the guide portion 200 under the action of the condensation's own gravity. In some specific embodiments, the converging surface 110 is curved. Compared to a flat surface, designing the converging surface 110 as a curved surface helps reduce the branching of condensation on the converging surface 110, thereby optimizing the condensation diversion effect.

[0035] Reference Figure 1 、 Figure 2 As shown, in some embodiments provided in the present application, the blocking portion 100 includes a cylindrical sleeve 120 and a conical sleeve 130, the cylindrical sleeve 120 is used to be sleeved on the surface of the wire harness 300, and the cylindrical sleeve 120 is gap-fitted with the outer wall of the wire harness 300, so that while fixing the conical sleeve 130, it can prevent condensation on the surface of the wire harness 300 from continuing to flow along the wire harness 300; the conical sleeve 130 has a small end and a large end, the diameter of the small end is smaller than the diameter of the large end, the small end is smoothly connected to one end of the cylindrical sleeve 120, and the large end is connected to the guide portion 200, and the inner wall of the conical sleeve 130 forms a converging surface 110. In this way, when the condensation on the surface of the wiring harness 300 flows through the connection position between the conical sleeve 130 and the cylindrical sleeve 120, the condensation is blocked by the cylindrical sleeve 120 and flows to the inner wall of the conical sleeve 130. Under the action of its own gravity, the condensation flows from high to low on the inner wall of the conical sleeve 130, and then all flows to the guide part 200, and reaches the position in the battery pack where there are no electrical components or fewer electrical components and the condensation can be discharged smoothly.

[0036] Reference Figure 1As shown, in some embodiments provided herein, a first opening 121 is defined on the cylindrical sleeve 120, and a second opening 131 is defined on the conical sleeve 130, with the first opening 121 and the second opening 131 being interconnected. Specifically, the first opening 121 extends axially through the cylindrical sleeve 120, and the second opening 131 extends along the busbar of the conical sleeve 130 from the small end to the large end. Thus, by passing the wiring harness 300 through the first and second openings 121 and 131, the cylindrical sleeve 120 and the conical sleeve 130 are integrally encased on the wiring harness 300, achieving quick clip-on securement. Specifically, the first opening is located on the side of the cylindrical sleeve away from the ground, and the second opening is located on the side of the conical sleeve away from the ground. Due to the effect of gravity, condensation flowing along the wiring harness is primarily concentrated on the side of the wiring harness closer to the ground. Therefore, by locating the first and second openings on the side away from the ground, it is possible to prevent some condensation from flowing from the first and second openings to the plug-in location at the end of the wiring harness. In some specific embodiments, the cylindrical sleeve 120 and the conical sleeve 130 are an integrally formed structure, and the material of the cylindrical sleeve 120 and the conical sleeve 130 is nylon, such as PA6, PA66 or PA6.6; this can make the cylindrical sleeve 120 and the conical sleeve 130 have a certain elasticity, and can produce a certain deformation amount when clamped, so as to facilitate clamping it on the wire harness 300; at the same time, it is ensured that there is a certain friction between the cylindrical sleeve 120, the conical sleeve 130 and the wire harness 300 to prevent relative rotation between the wire harness 300, so as to ensure that the guide part 200 is always located at a lower position of the conical sleeve 130 after being installed in place, so as to realize the diversion of condensation from high to low.

[0037] In some embodiments provided herein, the surface of the flow guide 200 is formed with a recessed portion 210 extending along the flow path. Specifically, the recessed portion 210 may be an arcuate groove or a V-shaped groove. In some embodiments, the upper surface of the flow guide 200 is arcuate, with the arcuate portion being lower near the centerline and higher near the sides. This creates a concave arcuate groove on the upper surface of the flow guide 200, allowing condensation on the conical sleeve 130 to flow along the centerline of the flow guide 200, preventing condensation from flowing out of the edges of the flow guide 200. In some embodiments, the side edges of the flow guide 200 are provided with a retaining edge 220 to prevent condensation from flowing out of the edges of the flow guide 200. In some embodiments, a bent section is provided at the end of the flow guide 200. The bent section serves as a transition between the flow guide 200 and other locations within the battery pack, thereby improving the stability of the flow guide 200.
