Description

Technical Field

[0001] The utility model relates to the technical field of cable ties, in particular to a cable tie used for bundling vehicle wiring harnesses. Background Art

[0002] Cable ties are a common binding tool that can be used to bind objects of different diameters through a retractable fastening ring. In the automotive field, they are mostly used to bind multiple wire harnesses.

[0003] Most of the existing cable ties are composed of a cable tie head and a cable tie strip. The connection between the cable tie strip and the cable tie head can be used to fix multiple wire harnesses. For example, a Chinese patent (application number: 202321481880.X) discloses a bolt-type cable tie that is easy to install and disassemble, including a cable tie head and a cable tie strip. The cable tie strip is fixedly connected to one side of the cable tie head. The cable tie head is provided with a clamping hole for the cable tie strip to be inserted. A fixing sleeve is fixedly provided on the side of the cable tie head away from the cable tie strip. The bottom end of the fixing sleeve is rotatably connected to a first baffle, the bottom of the first baffle is rotatably connected to a second baffle, the bottom end of the second baffle is rotatably connected to a threaded sleeve, and a plug-in rod is inserted into the fixing sleeve, and the bottom of the plug-in rod is threadedly connected to the threaded sleeve. The utility model makes it more convenient to install or disassemble the cable tie and the base plate, and at the same time makes the cable tie and the base plate more firmly fixed after being plugged in.

[0004] However, the cable tie has the problem of being difficult to operate because the screws need to be rotated to fix the cable tie during use, especially in the automobile assembly process, where it is more difficult to use tools to perform the rotation operation due to the small space. Utility Model Content

[0005] In order to solve the above problems, an embodiment of the utility model provides an anti-loosening type wire harness tie for automobile assembly, which has the advantages of good fixing effect and easy installation.

[0006] In order to achieve the above-mentioned purpose, the embodiment of the utility model specifically adopts the following technical scheme: an anti-loosening type wiring harness tie, comprising a tie body, a positioning module for fixing the position of the tie body is arranged on the upper part of the tie body, the positioning module comprises a plug-in column connected to the tie body, and an expansion ring plate is arranged on the side wall of the plug-in column.

[0007] As a further improvement of the above technical solution:

[0008] The number of the expansion ring plates is multiple and they are evenly distributed along the height direction of the plug-in column.

[0009] Each expansion ring plate is provided with an expansion notch, and the number of the expansion notches is at least two.

[0010] A positioning plate connected to the cable tie body is arranged at the lower part of the plug-in column, and a plug-in cone head is arranged at the top of the plug-in column.

[0011] The cable tie body comprises a cable tie head connected to a positioning plate, a cable tie strip is arranged at the lower part of the cable tie head, a clamping channel for penetrating the cable tie strip is arranged at the middle part of the cable tie head, and a locking tongue for locking the cable tie strip is arranged in the clamping channel.

[0012] The lower surface of the positioning plate is an arc-shaped protrusion, and the upper part of the clamping channel is provided with a avoiding groove corresponding to the position of the arc-shaped protrusion.

[0013] The beneficial effects of the embodiments of the utility model are as follows: 1. The anti-loosening wire harness tie comprises a tie body, the upper part of which is provided with a positioning module for fixing the position of the tie body, the positioning module comprises a plug-in column connected to the tie body, an expansion ring plate is provided on the side wall of the plug-in column, and the tie body can be positioned by plugging the plug-in column into the hole position, so that the tie body can be prevented from swaying with the wire harness and the wire harness can be fixed at the same time, the operation is simple and the fixing effect is good, and the design of the expansion ring plate can improve the plug-in stability of the plug-in column.

[0014] 2. The lower surface of the positioning plate is an arc-shaped protrusion, and the upper part of the card-joining channel is provided with a avoidance groove corresponding to the position of the arc-shaped protrusion. The lower end surface of the arc-shaped protrusion extends into the avoidance groove. Compared with the existing vertically arranged baffle, it can reduce the gap between the lock tongue and the upper part of the card-joining channel, thereby improving the locking strength.
