Description

Technical Field

[0001] This utility model belongs to the technical field of connectors, and more specifically, it relates to a terminal anti-retraction mechanism. Background Technology

[0002] With the ever-increasing demand for reliable connections in electronic devices, connector technology has been widely applied in fields such as communications, industrial control, and automotive electronics. Single-core connectors are favored due to their simple structure, ease of assembly and maintenance, and ability to ensure stable signal transmission. However, in practical use, the conductive terminals inside the connector often lack sufficient retaining or locking design between the conductive core (or plastic shell), making the terminals prone to loosening or displacement during mechanical vibration, external pulling, or frequent insertion and removal. Once the conductive terminals become loose, it can not only lead to poor contact and signal interruption, but may also cause short circuits or equipment failure, seriously affecting system stability and service life.
