Description

Technical Field

[0001] The utility model relates to the technical field of automobile wiring harness assemblies, in particular to an anti-stretching automobile wiring harness assembly. Background Art

[0002] The automotive wiring harness is the main network of the automotive circuit. The automotive wiring harness refers to the contact terminal (connector) made of copper material, which is crimped with the wires and cables, and then the insulator is plastic-pressed or metal shell is added to form a component that connects the circuit. The body wiring harness connects the entire body, and the general shape is H-shaped. The automotive wire is also called low-voltage wire, which is different from ordinary household wires. Ordinary household wires are single-core copper wires with a certain hardness. The automotive wires are all copper multi-core soft wires, some of which are as thin as hair. Several or even dozens of soft copper wires are wrapped in plastic insulating tubes (polyvinyl chloride), which are soft and not easy to break.

[0003] Currently, there are multiple electrical components inside the car, which need to be connected to the vehicle system through many wiring harness structures. Although the relative positions of most connected electrical components are determined, these components can be connected using wiring harnesses with fixed length and position. However, the positions of some electrical components will change. For example, the distance between the electrical components in the door and the main unit in the car will often change. To connect these components, it is necessary to reserve a certain stretch length for the wiring harness, which will cause the excessively long wiring harness to rub against the surrounding components and wear. If you want to reduce this wear, you need to reduce the reserved length and take the reserved length as the maximum extension length. However, due to thermal expansion and contraction, this extreme method can easily cause the wiring harness to be stretched. In order to prevent the wiring harness from breaking, the tensile strength of the wiring harness needs to be improved. However, after the tensile strength of the wiring harness is improved, it will cause interference to the relative components and affect the use effect. In view of this, we propose an anti-stretching automotive wiring harness assembly. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1.

During the deflection process, the turntable will drive the rotating shaft to rotate, and the rotation of the rotating shaft drives the flat scroll spring to deform, thereby buffering the tension encountered at both ends of the wiring harness assembly, thereby improving the tensile strength of the wiring harness assembly and avoiding the breakage of the wiring harness body due to the stretching effect.

[0015] 2. By setting a limit component, the limit component is installed on the circular plate in a detachable manner, and the limit hole opened in the limit plate has a limiting effect on the wiring harness body, thereby preventing the wiring harness body from detaching from the wiring groove 2 when the two ends of the wiring harness assembly are stretched and retracted and reset, which is beneficial to improving the stability of the tensile buffer component on the tensile buffer of the wiring harness assembly.

A winding roller 703 is fixedly installed, and wiring grooves 704 are equidistantly provided on the outer edge surface of the winding roller 703. A limiting component 8 is detachably installed between the outer edge surfaces of the circular plates 702 of the same group of winding components. Wire threading grooves 2 are symmetrically provided on the outer edge surface of the reserved wire box 1, and positioning components are symmetrically and equidistantly arranged and rotatably arranged in the wire threading grooves 2. The wiring harness assembly component 6 includes an assembly terminal 601 with a wiring harness body 602 equidistantly connected at one end. The end of the wiring harness body 602 away from the assembly terminal 601 enters and exits the wire threading groove 2 on the outer edge surface of the reserved wire box 1 and is wound in an S shape on the symmetrically arranged winding components.

[0026] To improve the stability of the tensile buffer component 7 on the tensile buffer of the wiring harness assembly component 6, see Figure 4 and Figure 5 The limiting assembly 8 includes a limiting plate 801 which is detachably mounted on the outer edge of the circular plate 702. Limiting holes 802 are equidistantly provided on the inner side surface of the limiting plate 801 at positions corresponding to the wiring groove 704, and fixing plates 803 are constructed at both ends of the outer side surface of the limiting plate 801.

When the two ends of the harness assembly component 6 are stretched, the position where the assembly end 601 contacts the wire groove 2 704 in the winding roller 703 will generate a driving force in the tangential direction of the outer edge of the winding roller 703, thereby forcing the winding component to drive the turntable 701 to deflect, and the turntable 701 will drive the shaft to rotate during the deflection process.
