Description

Technical Field

[0001] This utility model relates to an electrical connector, specifically a durable electrical connector with an anti-plugging impact structure. Background Technology

[0002] In industrial equipment, transportation vehicles, and mobile electronic devices, electrical connectors require frequent plugging and unplugging and must withstand mechanical vibration and impact. Traditional electrical connectors suffer from the following drawbacks: the pins and sockets make rigid contact without any cushioning structure. The instantaneous impact force generated by repeated plugging and unplugging can easily cause the pins to bend, the sockets to deform, or the plating to wear off, leading to poor contact or even electrical failure. Traditional snap-fit ​​or friction locking methods are prone to loosening under vibration (such as in bumpy vehicle conditions), causing signal interruption and, in severe cases, equipment shutdown. Furthermore, the precision terminals inside the connector are directly exposed to the path of external force, and lateral impacts can easily cause the shell to crack or the pins to break collectively.
