Novel wire harness binding strap

Abstract

The invention discloses a novel wire harness binding strap which comprises a locking part and a binding part and further comprises an inserting piece. One end of the binding part is fixedly connected with the locking part; the binding part is provided with a plurality of locating holes; the locking part is provided with a through hole; a shrapnel mechanism is arranged in the locking part and divides the through hole into an upper through hole body and a lower through hole body; and a hook-shaped part matched with the locating holes is arranged at the bottom of the shrapnel mechanism. The inserting piece is connected with the shrapnel mechanism in an inserted mode; guiding grooves which are mutually oppositely formed are formed in the two side walls of the upper through hole body; two guiding columns slidably matched with the guiding grooves are arranged on the inserting piece; each guiding groove is constituted by a horizontal section and an ascending section; and the ascending sections and the hook-shaped part are located at the same end. Shrapnel can be effectively prevented from breaking from the root due to improper operation, and the service life of the shrapnel is prolonged.

Description

technical field [0001] The invention relates to a cable tie, in particular to a novel cable tie. Background technique [0002] The safety and reliability of the fixing method of the automobile wiring harness is very important to the safety of the vehicle electrical system, and the interference and wear of the automobile wiring harness seriously affects the safe driving of the vehicle. [0003] In the prior art, the wiring harness of an automobile is usually fixed with a cable tie, which can effectively ensure the safety and reliability of fixing the wiring harness. The wire harness tie structure commonly used in the prior art is as figure 1 As shown, it includes a locking part 100 and a binding part 200. The locking part 100 has a spring structure 300 inside. The free end of the binding part 200 passes through the locking part 100, and is limited by the elastic structure 300 to prevent the binding part 200 from Loosen, play the role of fixing the wire harness.

AI Technical Summary

Problems solved by technology

[0004] The wire harness tie with this structure has many disadvantages, for example: the up and down movement range of the shrapnel structure 300 is uncontrollable, and it is easy to damage the shrapnel structure 300 if too much force is used during disassembly; the shrapnel structure 300 is greatly affected by natural conditions. Due to the principle of shrinkage, deformation will occur as the temperature changes, affecting normal use; the strength of the shrapnel mechanism 300 is relatively poor, and it is easy to break or be forced to separate from the binding part 200 under the action of a large external force
