Description

Technical Field

[0001] The utility model relates to the technical field of wire harness threading, in particular to an auxiliary device for threading a bent pipe of an automobile wire harness. Background Art

[0002] The automotive wiring harness is the main network of the automotive circuit. It is responsible for connecting the various electronic components of the car to ensure the normal operation of the vehicle. The automotive wiring harness threading refers to the process of passing the wires through silicone tubes, waterproof plugs or other protective devices during the manufacturing process of the automotive wiring harness. This step is usually performed in the pre-installation stage to protect the wires from the influence of the external environment, such as moisture, dust and chemicals, and also to ensure the overall beauty and functionality of the wiring harness;

[0003] The utility model with application number 202321190495.X discloses a wire harness protective sleeve threader. By sliding the second connector into the first connector, the second sleeve body can be connected to the first sleeve body. The second elastic clip and the first elastic clip have elasticity to clamp the wire harness, so that the device can be fixed at one end of the wire harness and the terminal of the wire harness can be protected to prevent damage to the terminal of the wire harness during threading. The guide head provided at the end can facilitate the insertion of the device into the sleeve. The rotation of the wire harness can drive the sleeve to rotate. The guide head is an oblique cone to change the guiding direction, so that the device can be inserted into the sleeves with different inclined directions.

[0004] However, in the above-mentioned wire harness protective cover threader, the first sleeve body and the second sleeve body are combined into a rigid vertical structure, which makes it impossible to guide the wire harness to be threaded along the curved pipe, resulting in low threading efficiency of the wire harness in the curved pipe. When threading, the above-mentioned wire harness protective cover threader needs to be manually pushed from the rear of the wire harness continuously, which easily causes the wire harness to be blocked in the curved pipe, affecting the threading efficiency. Therefore, the utility model proposes an automobile wire harness curved pipe threading auxiliary device to solve the problems existing in the prior art. Utility Model Content

The characteristics of the flexible rubber sleeve 2 are utilized to facilitate the wire threading tube 1 to drive the automobile wiring harness to move in multiple directions and angles, thereby solving the problem that the wire threader for guiding the wiring harness is a rigid vertical structure and cannot guide the automobile wiring harness along the curved pipe for threading, thereby effectively improving the threading efficiency of the wiring harness in the curved pipe.

[0020] The wire-threading covers 5 are divided into two groups. One group of wire-threading covers 5 has positioning holes 6 arranged on the inner side, and the other group of wire-threading covers 5 has positioning posts 7 arranged and fixed on the inner side. The positions and sizes of the positioning holes 6 and the positioning posts 7 correspond to each other.
