Description

Technical Field

[0001] The utility model belongs to the technical field of automobile wiring harness production, and specifically relates to an electrical box sheath positioning seat for automobile wiring harness production. Background Art

[0002] The automotive wiring harness is an important component of the internal circuit of the car. The terminals of the wiring harness are plugged and fixed to complete the assembly of the automotive circuit and realize the signal and electrical transmission of the internal circuit of the car. In the process of manufacturing the automotive wiring harness, the crimped terminals need to be inserted into the sheath to ensure the stability of the connection with the electrical appliances in the car. However, some large electrical box sheaths contain a lot of wiring harnesses and terminals. After the pre-installation is completed, when the cable cloth and sleeve are wound on the assembly line tooling board to adjust the precise size of each branch of the wiring harness, it is inconvenient to operate the multi-wiring harness corresponding to the large electrical box sheath, because such an electrical box sheath is not easy to position. The previous processing method is generally to open a mold according to the shape of the electrical box sheath to manufacture a completely fitting positioning seat, but this method not only requires a high mold opening cost each time, but also is not convenient to use. After the electrical box sheath is completely placed in the positioning seat, the wiring harness is bent. Poor quality wiring harnesses may fail, resulting in product scrapping.

[0003] In the prior art, the patent document with the announcement number CN208067126U discloses an auxiliary support seat for crimping of automobile wiring harness terminals, including a crimping lower die, an arc groove matching the crimping interface on the crimping punch is provided on the upper part of the crimping lower die, the crimping lower die is arranged in a positioning groove provided in the positioning seat, a sliding groove is provided on the side of the positioning seat opposite to the positioning groove, the positioning seat is connected to the stamping table through a fixed pad, a telescopic mechanism fixedly connected to the stamping table is provided on one side of the fixed pad, the telescopic rod in the telescopic mechanism is horizontally slidably arranged in the sliding groove, and a baffle for pressing against the terminal is provided at the end of the telescopic rod. The above technical scheme improves the efficiency and quality of crimping of automobile wiring harnesses and terminals, but cannot solve the problem of accurate positioning of the length of the terminal branch line, especially the problem of combing and length adaptive adjustment and positioning of numerous wiring harnesses in the electrical box sheath needs to be solved urgently.
