Problems solved by technology

In this scheme, the clips, the connectors of the clips and the cable ties have various components, and the structure of each component is complicated. The overall fastening effect is damaged due to the loosening or falling off of the components; the clips of this device cannot be rotated on the same plane, and the assemblability is poor; Under the action of long-term lateral force, the contact area between the reversible fixing mechanism and the wedge block becomes smaller, eventually causing the fixing mechanism to come out, causing the clip to disengage and lose its fixing function

Embodiment 1

[0047] Example 1 A harness fastening device

[0048] This embodiment includes a cable tie, a connector 2-3 for fixed connection with the cable tie, and an open C-shaped claw 1 that can be clamped on the outer periphery of the pipeline 4 for fixed connection with the connector 2-3.

[0049] Such as figure 2 , Figure 4 As shown, the cable tie includes a belt body 2-1 and a lock tongue 2-2. The working surface of the belt body 2-1, that is, the front has barbs to ensure that the free end of the belt body 2-1 passes through the lock tongue in one direction. After 2-2, it can be locked without releasing.

[0050] refer to figure 1 and image 3 , The outer peripheral surface of the claw 1 is provided with an I-shaped cylindrical structure boss 1-2 protruding in the radial direction, and the boss 1-2 is a coupling point between the claw 1 and the connecting piece 2-3. A plurality of bosses 1-2 are arranged at intervals along the circumferential direction on the outer periphe...

Embodiment 2

[0055] Example 2 A harness fastening device

[0056] The difference between this embodiment and embodiment 1 only lies in:

[0057] The main body of the claw is an open ellipse;

[0058] The outer peripheral surface of the claw is provided with a plurality of boss fixing points spaced apart along the extending direction of the outer peripheral surface. The boss is a prefabricated structure, which can be fixed on the boss by welding, riveting, threaded connection, etc. according to the required angle. fixedly connected to the jaws. This connection method determines the number of bosses and installation angles according to the actual situation during assembly, which can avoid waste of components, reduce the weight of components, reduce the volume of components, and avoid interference with surrounding components.

Embodiment 3

[0059] Example 3 A harness fastening device

[0060] The difference between this embodiment and Embodiment 1 is that: the main body of the claw is an open ellipse.

Abstract

The invention discloses a wire harness fastening device, which includes a wire harness tie, a connecting piece used for fixed connection with the wire harness tie, and an open ring claw used for fixed connection with the connecting piece that can be clamped on the outer circumference of a pipeline. The outer surface of the claw is detachably connected to the connecting piece, and the angle between the plane where the claw is located and the connecting piece is adjustable. In the present invention, after the wire harness is bundled up by the cable tie, the cable tie is fixed on the pipeline through an open annular claw fixedly connected with the cable tie. The setting angle of the claw can be adjusted, so that the cable tie can be fixed on the pipeline in different directions. The invention has a small number of constituent components, simple structure of each component, simple and easy assembly among the components, low matching precision requirement, and wide application range of the wiring harness fastening device. The invention is applicable to various vehicles and binds and fixes the wiring harness at the pipeline.

Description

technical field [0001] The invention belongs to the technical field of wiring harness fastening, in particular to the fastening and fastening of vehicle wiring harnesses, in particular to a wiring harness fastening device. Background technique [0002] During the driving process of the vehicle, if the wire harness is not fixed firmly, it will swing, which will cause scratches with adjacent metal parts, resulting in interference and wear, and reducing the service life of the wire harness. [0003] The existing vehicle wiring harnesses are mainly fixed by using cable ties or pipe clamps. Among them, although cable ties can solve the problem of messy wire harnesses, and the assembly method is simple, they cannot completely fix the wire harnesses, and the firmness is poor; although the pipe clamps are strong, they need to be connected and fixed by bolts, and the scope of application is limited. . [0004] The Chinese patent literature database discloses a utility model patent ...
