Technical Field

[0001] This utility model relates to the field of wiring harness assembly technology, specifically to an electric vehicle wiring harness assembly. Background Technology

[0002] An electric vehicle wiring harness assembly is a crucial component that integrates and assembles the connecting wires between various electrical devices and components in an electric vehicle. It consists of multiple wires, connectors, protective sleeves, and other electrical parts, and through proper wiring and insulation design, effectively connects and transmits power, signals, and data within the electric vehicle.

[0003] Existing electric vehicle wiring harness assemblies typically use clip-on structures to connect and secure the two ends for ease of installation and fixation. However, this structure is prone to loosening at both ends when subjected to external forces, potentially leading to poor wiring contact and affecting the normal operation of the electric vehicle. Therefore, we propose an electric vehicle wiring harness assembly to solve the aforementioned problems. Summary of the Invention

[0004] The purpose of this utility model is to provide an electric vehicle wiring harness assembly to solve the problem mentioned in the background art that existing electric vehicle wiring harness assemblies typically use a snap-fit ​​structure to connect and fix the two ends for easy installation and fixation of the wiring harness. However, when this structure is shaken by external forces, the interfaces at both ends are prone to loosening, which may lead to poor contact of the wiring harness and affect the normal use of the electric vehicle.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0011] Furthermore, the outer side of the tightening cone sleeve is provided with multiple anti-slip grooves that rotate evenly around the axis. The diameter of the inner side of the tightening cone sleeve away from the top spring is smaller than the diameter of the inner side near the top spring. The inner side of the tightening cone sleeve is threadedly connected to the outer side of multiple elastic strips.

[0012] Furthermore, the socket is fixedly connected to the inside of the base.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Please see Figures 1-4 This utility model provides a technical solution: an electric vehicle wiring harness assembly, including a wiring harness assembly 1, a plug component 2 at one end of the wiring harness assembly 1, a fixing seat component 3 at the other end of the wiring harness assembly 1, a tightening spring 4 on the outer side of the fixing seat component 3 away from the wiring harness assembly 1, a socket 5 on the inner side of the fixing seat component 3 away from the wiring harness assembly 1, and a tightening cone sleeve 6 at the other end of the tightening spring 4;

[0022] The fixed base component 3 includes a base 301, and a plurality of elastic strips 302 are evenly and spaced around the top of the base 301, and each of the multiple elastic strips 302 has a buckle 303 on its top.

[0023] The plug component 2 includes a retainer 201, a slot 202 is provided on the bottom outer side of the retainer 201, and a plug 203 is provided on the inner side of the retainer 201. The retainer 201 is fixedly connected to one end of the wire harness assembly 1, and the plug 203 is fixedly connected to the retainer 201. In this example, by providing the slot 202, it is easy for the buckle 303 to engage, thereby fixing the plug component 2.

[0024] The base 301 is fixedly connected to the other end of the wiring harness assembly 1. One end of each of the multiple elastic strips 302 is fixedly connected to the base 301, and multiple clips 303 are fixedly connected to the multiple elastic strips 302 respectively. In this example, by setting the elastic strips 302, they can deform, which facilitates the clips 303 to snap into the slots 202.

[0025] One end of the clamping spring 4 is fixedly connected to the base 301, and the other end of the clamping spring 4 contacts the bottom of the tightening cone sleeve 6. In this example, by setting the clamping spring 4, a pushing force can be applied to the bottom of the tightening cone sleeve 6 to prevent loosening.

[0026] The tightening cone sleeve 6 has multiple anti-slip grooves 601 evenly rotated around its axis on its outer side. The diameter of the end of the tightening cone sleeve 6 furthest from the top spring 4 is smaller than the diameter of the end closest to the top spring 4. The inner side of the tightening cone sleeve 6 is threadedly connected to the outer sides of multiple elastic strips 302. In this example, by setting the tightening cone sleeve 6, multiple elastic strips 302 can be pressed together, thereby allowing the buckle 303 to be securely engaged in the slot 202.

[0027] The socket 5 is internally fixedly connected to the base 301.

[0028] Working principle: By aligning the fixing base component 3 with the plug component 2 on another wire harness assembly 1 and inserting it, the elastic strip 302 bends, causing the buckle 303 to slide across the card seat 201 and engage with the card slot 202. The plug 203 is inserted into the socket 5. Then, through the anti-slip texture 601, the tightening cone sleeve 6 is rotated, thereby pressing multiple elastic strips 302, so that multiple buckles 303 are firmly locked inside the card slot 202. During this process, the top spring 4 presses against the bottom of the tightening cone sleeve 6 to prevent the tightening cone sleeve 6 from loosening. When it is necessary to remove the wire harness assembly 1, by rotating the tightening cone sleeve 6, the top spring 4 is compressed, thereby releasing the elastic strip 302. The base 301 is pulled outward, causing the elastic strip 302 to deform, which drives the buckle 303 to disengage from the card slot 202, and the plug 203 is released.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
