Description

Technical Field

[0001] The utility model relates to the technical field of wire harness processing equipment, in particular to a center pin short circuit testing device. Background Art

[0002] The center pin of wire crimping refers to the component used to connect the inner conductor of the wire or cable during the crimping process. It is usually made of metal and has a tapered or conical cutting mouth so that the conductor part of the wire can be firmly connected. The center pin plays the role of guiding and fixing the wire during the crimping process to ensure good electrical connection and mechanical strength.

[0003] In order to achieve automated production and ensure the quality of processed products, some cables need to be short-circuited after crimping the center pin. Common short-circuit detection methods include using a multimeter or a dedicated short-circuit detection instrument to measure the resistance between the wires or use a circuit test to ensure that there is no abnormal low-resistance path at the connection. However, traditional manual operations are inefficient and the quality cannot be guaranteed. There is currently no effective automated center pin short-circuit test device. It is now necessary to develop a center pin short-circuit test device to improve the wire harness production efficiency and lay the foundation for the stable progress of subsequent wire harness processing processes.
