Terminal plugging tool for automobile harness connectors

Abstract

A terminal plugging tool for automobile harness connectors comprises a trough housing, a weight module, a counting proximity switch and a monitoring circuit. A horizontal partition is disposed in the trough housing. The weight module is arranged above the horizontal partition. Side walls of the weight module are in sliding connection with the inner wall of the trough housing. A sheath locker and a sheath trough matching with a sheath of a harness connector are arranged on the top of the weight module. Vertical guide bars are fixedly connected to the bottom of the weight module. The guide bars penetrate through the horizontal partition. A limit disk is disposed on the lower portion of each guide bar. The counting proximity switch is disposed on the inner wall of the trough housing and corresponds to a counting groove on one side wall of the weight module. Switching signals output by the counting proximity switch are transmitted to an input end of the monitoring circuit. Potential failures of the wire connector caused by poor terminal plugging or improper resilience of a terminal can be eliminated by the use of the terminal plugging tool. By the use of the terminal plugging tool, failure rate of the connectors can be reduced greatly and reliability of automobile harnesses can be improved.

Description

technical field [0001] The invention relates to a tool for plugging a terminal in a plastic sheath of an automobile wiring harness connector, which belongs to the technical field of automobiles. Background technique [0002] The wiring harness connector is an important part of the vehicle wiring harness, and its working reliability is closely related to the performance of the vehicle. With the rapid development of automotive electronics technology, the number of terminals in wiring harness connectors is increasing, especially in the connectors of some electronic controllers (such as BCM), the number of terminals is often as many as dozens or even hundreds, and any one of them Terminal failure will lead to the failure of certain control functions, so automobile manufacturers have higher and higher requirements for the reliability of wiring harness connectors. [0003] The harness connector is mainly composed of a plastic sheath and a terminal crimped on the end of the wire. ...

AI Technical Summary

Problems solved by technology

However, due to the complex structure of the harness connector and the large number of terminals, the operator often misses the pull-back operation of some terminals, so the connection reliability of the connector cannot be guaranteed

In addition, different operators often have different strengths in pulling back the terminals. If the strength is too high, the terminals will be damaged, but if the strength is too small, the detection effect will not be achieved. Therefore, the uncontrollable pullback strength of the terminals is also currently affecting the quality of wiring harness assembly. Key factor
