Description

Technical Field

[0001] The utility model relates to the field of automobile wiring harnesses, in particular to an automobile wiring harness with a tensile resistance function. Background Art

[0002] Automotive wiring harness refers to a group of wires, cables and connectors inside a car that are organized into a whole and transmit power and signals through different components and systems of the vehicle. Automotive wiring harnesses are usually composed of multiple strands of wires, insulating sleeves, connectors, terminals, etc. to facilitate the transmission of power and information inside the vehicle.

[0003] Existing automotive wiring harnesses do not have a tensile effect when in use. When the wiring harness is pulled, it is easy to tear, causing damage to the wiring harness. In addition, when multiple strands of wiring harnesses are concentrated, they are easy to entangle with each other, making them inconvenient to store, which has a certain impact on actual use. Utility Model Content

[0004] The purpose of the utility model is to provide an automobile wiring harness with a tensile resistance function. The utility model effectively solves the technical problems raised in the background technology.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A car wiring harness with a tensile resistance function comprises a cable, both ends of the cable are connected with connectors, a box is provided in the middle of the cable, a wire take-up wheel is provided inside the box, shaft seats are installed on both sides of the box, shaft rods are fixedly connected on both sides of the wire take-up wheel, and the ends of the shaft rods are rotatably connected to the shaft seats, a coil spring is provided inside the shaft seat, and the ends of the shaft rods are fixedly connected to one end of the coil spring, and the other end of the coil spring is fixedly connected to the shaft seat.

[0007] As a further solution of the utility model, one end of the cable passes through the front of the box and is wound around the outside of the take-up wheel, and one end of the cable passes through the rear of the box.

[0008] As a further solution of the utility model, the upper and lower ends of the box body are connected to limit plates, a pull rod is connected to the outside of the limit plate, one end of the pull rod located inside the limit plate is connected to a pressure plate, and the outer part of the pull rod located between the pressure plate and the limit plate is sleeved with a spring.

[0009] As a further solution of the utility model, the limit plate is arranged in a U shape, and the horizontal length of the limit plate is equal to that of the box body.

[0010] As a further solution of the utility model, winding wheels are installed at the upper front part and the lower rear part of the box body.

[0011] As a further solution of the utility model, the front and rear parts of the box body are both provided with slots for cables to pass in and out, and the slots are arranged in a circular shape.

[0012] Beneficial effects of the utility model:

[0013] The utility model provides a take-up wheel in cooperation with a shaft rod and a winding spring, so that the take-up wheel can reel in part of the cable, so that when the cable is pulled, the rotation of the take-up wheel can be used to release the cable to the outside of the box, thereby increasing the length of the cable, thereby achieving a tensile resistance effect and preventing the cable from being damaged by being pulled.

[0014] As the take-up wheel rotates, the shaft rod rotates, which can drive the winding spring to be tightened. When the joint is not under stress, the shaft rod can be driven to rotate by resetting the winding spring, which further drives the take-up wheel to rotate, so that part of the cable is rewound around the outside of the reel for easy recovery.

[0015] By setting a winding wheel in conjunction with a limit plate, the cable located on the outside of the box is wound on the outside of the winding wheel, and then the connector is inserted into the inside of the limit plate. The pressure plate is driven up by the pull rod, and as the spring resets, the connector can be fixed by the pressure plate in conjunction with the limit plate, which makes it convenient to store the connector, thereby making it convenient to store the entire automotive wiring harness and avoid the problem of entanglement when multiple wiring harnesses are stored together.

[0023] One end of the cable 1 passes through the front of the box 3 and is wound around the outside of the take-up wheel 6 , and one end of the cable 1 passes through the rear of the box 3 .

[0024] After the cable 1 is inserted into the box body 3 , it is wound around the outside of the take-up wheel 6 and then passes out from the rear of the box body 3 , so that the cable 1 can be stored.

[0025] The upper and lower ends of the box body 3 are connected to the limit plate 5, and a pull rod 10 is connected to the outside of the limit plate 5.
