[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0023] Example 1: Please refer to Figure 1 、 Figure 4-Figure 7 In order to integrate the wiring harness into a whole, the present embodiment provides the following technical solutions, which specifically disclose: an outer protective cover 1 with a strip-shaped structure, and a connecting wire harness 2 is provided inside the outer protective cover 1, and a connecting connector 3 is fixedly installed on the top of the front and rear sides of the connecting wire harness 2. The connecting wire harness 2 is divided into two parts: a wire harness inner core 201 and a protective rubber cover 202. The cross-section of the outer protective cover 1 is a flat structure, and the connecting wire harness 2 is evenly arranged at equal intervals inside the outer protective cover 1. A reinforcement ring 11 is fixedly provided on the outer surface of the outer protective cover 1, and the reinforcement ring 11 is set to a rubber material, and the reinforcement ring 11 is evenly arranged at equal intervals as a whole. Sponge pads 13 are fixedly installed on the upper and lower sides of the inner part of the outer protective cover 1, and a wire management clip 12 is fixedly installed on the outer surface of the sponge pad 13. The clamp 12 clamps and fixes the connecting wire harness 2, and movable sleeves 14 for limiting the bending position of the connecting wire harness 2 are installed at the front and rear ends of the outer protective cover 1, and the movable sleeve 14 is sleeved on the outside of the connecting wire harness 2. A sliding structure is formed between the movable sleeve 14 and the connecting wire harness 2, and a folded extension cover 15 is fixedly installed between the movable sleeve 14 and the outer protective cover 1, and an elastic connecting plate 16 is fixedly installed on the side of the movable sleeve 14, and a guide roller 17 for contacting the connecting wire harness 2 when bending is fixedly installed on the top of the connecting plate 16. The outer protective cover 1 is divided into a braided layer 101, a flame retardant layer 102, an electromagnetic shielding layer 103 and an outer layer 104 from the inside to the outside. The braided layer 101 is set to a nylon braided mesh structure, and the flame retardant layer 102 is set to polyvinyl chloride material.

[0024] When producing the harness assembly, a group of connecting harnesses 2 that need to be used are gathered together, and then the outer protective cover 1 is wrapped around the outside of the connecting harness 2. At this time, the connecting harness 2 is clamped and fixed with the wire management clip 12 inside the outer protective cover 1, and finally the connecting connector 3 is fixedly installed at the front and rear ends of the connecting harness 2. The outer surface of the outer protective cover 1 is provided with reinforcement rings 11 arranged at equal intervals. The reinforcement rings 11 are used to enhance the overall strength of the outer protective cover 1. At the same time, the sponge pad 13 inside the outer protective cover 1 provides elastic buffering force to improve the overall pressure resistance effect. According to the specific use needs of the harness assembly, the movable sleeve 14 is slid outside the connecting harness 2 (the movable sleeve 14 is used to limit the separation position of the connecting harness 2). During the sliding process of the movable sleeve 14, the extension cover 15 is driven to extend and retract, so that the extension cover 15 remains outside the connecting harness 2, thereby improving the protection effect. When the connecting harness 2 is bent, the guide roller 17 on the side of the movable sleeve 14 squeezes the connecting plate 16, and the elastic effect of the connecting plate 16 is used to achieve a supporting effect, thereby preventing the connecting harness 2 from being excessively bent and broken.

[0025] Example 2: Please refer to Figure 1-Figure 3In order to solve the problem that the traditional wiring harness falls off due to shaking during use, this embodiment provides the following technical solutions, which specifically disclose: a mounting plate 4 for vehicle connection is provided on the outside of the outer protective cover 1, and a clamping block 5 is provided on the outer surface of the mounting plate 4 to match it, and the clamping block 5 is in an "n"-shaped structure for clamping the outer protective cover 1, and the mounting plate 4 is fixedly connected to the body structure of the car by a fixing bolt 6, and a disassembly and installation mechanism is provided between the clamping block 5 and the mounting plate 4, and the disassembly and installation mechanism includes a fixing buckle 8 rotatably installed on the side of the clamping block 5, and the fixing buckle 8 and the mounting plate 4 are fixedly engaged and fixed with each other, and a connecting spring 9 is fixedly installed between the upper surface of the fixing buckle 8 and the side of the clamping block 5, a first extrusion block 7 is fixedly installed in the middle position of the upper surface of the mounting plate 4, and a second extrusion block 10 is fixedly installed on the lower surface of the clamping block 5, and the surfaces of the first extrusion block 7 and the second extrusion block 10 are both provided with a rough structure.

[0026] When using the wiring harness assembly to connect the headlights to the vehicle's electronic control system, first dock one end of the connecting connector 3 with the electronic control system, then dock the other end of the connecting connector 3 with the headlight wiring component 18, then use the fixing bolts 6 to fix the mounting plate 4 to the appropriate position of the vehicle body, and place the front and rear ends of the outer protective cover 1 on the two mounting plates 4 respectively. Then, place the clamping block 5 against the mounting plate 4, and use the connecting spring 9 to squeeze the fixing buckle 8 to fix the clamping block 5 and the mounting plate 4 in a fixed engagement connection. At this time, the outer protective cover 1 is fixed under the extrusion and friction between the first extrusion block 7 on the upper surface of the mounting plate 4 and the second extrusion block 10 on the lower surface of the clamping block 5, thereby reducing the shaking of the wiring harness assembly during vehicle driving. According to actual needs, the clamping block 5 can be removed to adjust the position of the outer protective cover 1 and then fixed to achieve the best fixing effect.

[0027] Example 3: Please refer to Figures 8-10 In order to achieve the purpose of fixing the connecting joint 3, this embodiment provides the following technical solutions, which specifically disclose: the connecting joint 3 and the wiring port on the surface of the headlight wiring component 18 are engaged with each other, and a stabilizing mechanism for fixing it is provided on the outside of the connecting joint 3, and the stabilizing mechanism includes an inflation airbag 19 fixedly installed on the outer surfaces of the left and right sides of the connecting joint 3 and a fixing plate 20 rotatably installed on the upper and lower sides of the connecting joint 3, and the inflation airbag 19 extends into the interface of the headlight wiring component 18, and an adhesive tape 21 for pasting with the headlight wiring component 18 is fixedly installed on the outer surface of the fixing plate 20, and the outer surface of the protective rubber sleeve 202 is fixedly installed with heat dissipation fins 22 arranged at equal intervals, and the heat dissipation fins 22 are set to be made of soft aluminum alloy, and a protective spring 23 is fixedly installed on the outside of the heat dissipation fin 22.

[0028] When the connecting joint 3 is docked with the headlight wiring component 18, the expansion airbags 19 on the left and right sides of the connecting joint 3 enter the interior of the interface, thereby utilizing the expansion and squeezing effect of the expansion airbags 19 to increase the friction force, and then flip the upper and lower fixing plates 20, and utilize the adhesive tape 21 on the surface of the fixing plate 20 to stick and fix it to the headlight wiring component 18, thereby finally achieving the purpose of fixing the connecting joint 3 and preventing it from falling off. Heat dissipation fins 22 are provided on the outer surface of the front and rear ends of the connecting harness 2 near the connecting joint 3, and the heat dissipation fins 22 are utilized to increase the surface area at the high point, thereby enhancing the heat dissipation effect, and avoiding the position from being overheated and accelerated aging damage due to being close to the headlight. At the same time, a protective spring 23 is installed through the internal fixing of the heat dissipation fin 22, and the elastic effect of the protective spring 23 is utilized to enhance the anti-bending effect.
