Description

Technical Field

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

[0002] Automotive wiring harnesses are the main network of automotive circuits; without wiring harnesses, there would be no automotive circuits. A wiring harness is an assembly that connects circuits by crimping copper contact terminals (connectors) to wires and cables, then molding an insulator or adding a metal shell, and finally bundling the wires together.

[0003] Patent CN217768925U discloses an automotive wiring harness, which includes a wiring harness head and electronic wires. One end of the wiring harness head is connected to the electronic wires. A side block is connected through the surface of the electronic wires. A rotating shaft is movably connected to the surface of the side block. A pressure plate is connected through the surface of the rotating shaft. The pressure plate is rotatably connected to the side block with the rotating shaft as the center. This device can wind up classified electronic wires, thereby avoiding the electronic wires from becoming tangled. It can effectively prevent automotive wiring harnesses from becoming tangled due to excessive winding. At the same time, the tape wrapped on the automotive wiring harness will not corrode and cause damage to the electronic wires.

[0004] However, the length of the electronic wires in this device is fixed, and automotive wiring harnesses generally have extra length. This means that after connecting electrical equipment using the wiring harness head, if you want to ensure the wiring harness is neat and aesthetically pleasing, you need to wrap and bind the extra electronic wires with tape or cable ties. This process is not only cumbersome, but it also affects subsequent wiring harness maintenance and repair. Therefore, an automotive wiring harness is proposed to solve the problem that existing automotive wiring harnesses are difficult to adjust in length according to the connection position. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an automotive wiring harness that solves the aforementioned problems.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an automotive wiring harness, including a fixed housing, slots on both sides of the fixed housing, an automotive wiring harness body disposed within the inner cavity of the fixed housing, connectors fixedly connected to both ends of the automotive wiring harness body, a limiting mechanism disposed within the inner cavity of the slots, a cover disposed on the top of the fixed housing, the cover being bolted to the top of the fixed housing, two movable slots being formed on the top of the cover, two T-shaped slots being formed at the bottom of the inner cavity of the fixed housing, T-shaped blocks being slidably disposed within the inner cavity of the T-shaped slots, two limiting posts disposed within the inner cavity of the fixed housing, external threads being provided on the outer ring of the limiting posts, a limiting cap disposed on the top of the limiting posts, and internal threads being provided on the inner ring of the limiting cap.

[0009] Preferably, the limiting post is fixedly connected to the T-block, the surface of the limiting post is smooth, and the two limiting posts and the two T-blocks are centrally symmetrically distributed.

[0010] Preferably, the limiting post extends through the moving groove and the two are slidably connected, the bottom of the limiting cover is rough, and the two moving grooves are centrally symmetrically distributed.

[0011] Preferably, a label plate is provided at one end of the fixing shell.

[0012] Preferably, the outer ring of the limiting cover is provided with anti-slip texture.

[0013] Preferably, the limiting mechanism includes mounting grooves symmetrically opened at both ends of the inner cavity of the slot, the inner cavity of the mounting groove is provided with a limiting block, the limiting block is made of elastic rubber, and a limiting groove adapted to the automotive wiring harness body is opened through one side of the limiting block.

[0014] (III) Beneficial Effects

[0015] 1. This automotive wiring harness, when stretched to its maximum length, is connected to the desired position via a connector. Based on the excess length of the wiring harness, the limiting post is moved towards the center by the T-shaped block within the T-slot and the moving groove on the cover, thereby retracting the excess wiring harness into the fixed housing. Then, the limiting cover is rotated, engaging the external and internal threads, to press against the cover, thus fixing the position of the limiting post. This solves the problem of existing automotive wiring harnesses having difficulty adjusting length according to the connection position.

[0016] 2. This automotive wiring harness allows for length adjustment. The length of the wiring harness body is adjusted by using a limiting groove in a rubber limiting block within the mounting slot to limit the wiring harness body. Specifically, when adjusting the harness length, the limiting block applies pressure to the wiring harness body, initially limiting the harness and confining any excess wiring within the fixed housing. This facilitates length adjustment and improves the ease of the wiring harness adjustment process. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figure 1-4An automotive wiring harness includes a fixed housing 1, slots 2 on both sides of the fixed housing 1, an automotive wiring harness body 3 inside the fixed housing 1, connectors 4 fixedly connected to both ends of the automotive wiring harness body 3, a limiting mechanism 6 inside the slots 2, a cover 7 on the top of the fixed housing 1, the cover 7 being fixed to the top of the fixed housing 1 by bolts 8, two movable slots 9 on the top of the cover 7, two T-shaped slots 10 at the bottom of the inner cavity of the fixed housing 1, T-shaped blocks 11 slidably disposed inside the inner cavity of the T-shaped slots 10, two limiting posts 12 inside the fixed housing 1, external threads 13 on the outer ring of the limiting posts 12, a limiting cover 14 on the top of the limiting posts 12, and internal threads 15 on the inner ring of the limiting cover 14.

[0024] Furthermore, the limiting post 12 is fixedly connected to the T-block 11. The surface of the limiting post 12 is smooth. The two limiting posts 12 and the two T-blocks 11 are centrally symmetrically distributed. The smooth surface of the limiting post 12 reduces the friction between the car wiring harness body 3 and the limiting post 12, thus preventing damage to the wiring harness.

[0025] Furthermore, the limiting post 12 extends through the moving groove 9 and the two are slidably connected. The bottom of the limiting cover 14 is rough, and the two moving grooves 9 are centrally symmetrically distributed. The rough bottom of the limiting cover 14 increases the friction when the limiting cover 14 contacts the sealing cover 7, thereby improving the firmness of the limiting post 12 after it is fixed in position.

[0026] Furthermore, a label plate 5 is provided at one end of the fixed shell 1, on which the location information of the vehicle wiring harness body 3 is connected can be written and then pasted on the label plate 5, thereby facilitating the subsequent maintenance and repair of the vehicle wiring harness.

[0027] Furthermore, the outer ring of the limiting cover 14 is provided with anti-slip texture 16, which increases the friction between the limiting cover 14 and the hand, making it easier to rotate the limiting cover 14 to fix the position of the limiting post 12.

[0028] Furthermore, the limiting mechanism 6 includes mounting grooves 601 symmetrically opened at both ends of the inner cavity of the slot 2. The inner cavity of the mounting groove 601 is provided with a limiting block 602. The limiting block 602 is made of elastic rubber. One side of the limiting block 602 is provided with a limiting groove 603 adapted to the automotive wiring harness body 3. When the length of the automotive wiring harness body 3 is adjusted, the limiting groove 603 in the rubber limiting block 602 in the mounting groove 601 is used to limit the automotive wiring harness body 3. That is, when the length of the wiring harness is adjusted, the squeezing force of the limiting block 602 on the automotive wiring harness body 3 is used to initially limit the wiring harness, so that the excess wiring harness is limited in the fixed shell 1, thereby facilitating the adjustment of the length of the automotive wiring harness body 3 and improving the convenience of the automotive wiring harness adjustment process.

[0029] Working principle: When using this automotive wiring harness, the main body 3 is stretched to its maximum length. After connecting the main body 3 to the desired position via the connector 4, based on the excess length of the main body 3, the limiting post 12 is moved towards the center under the action of the T-shaped block 11 in the T-slot 10 and the moving groove 9 on the cover 7, thereby retracting the excess main body 3 into the fixing housing 1. Then, the limiting cover 14 is rotated, engaging the external thread 13 and the internal thread 15, until the limiting cover 14 is pressed against the cover 7, thus fixing the position of the limiting post 12. This invention solves the problem of existing automotive wiring harnesses having difficulty adjusting their length according to the connection position. By adjusting the length of the automotive wiring harness body 3, and cooperating with the limiting groove 603 in the rubber limiting block 602 within the mounting groove 601, the automotive wiring harness body 3 is limited. That is, when adjusting the length of the wiring harness, the limiting block 602 applies pressure to the automotive wiring harness body 3 to initially limit the wiring harness, so that the excess wiring harness is limited within the fixing shell 1, thereby facilitating the adjustment of the length of the automotive wiring harness body 3 and improving the convenience of the automotive wiring harness adjustment process.
