The collar is sleeved on the outer side surface of the plug housing, and the barb is clamped in the slot; the spring, washer, tension spring, and bushing are pressed against the outside of the plug housing by using the elastic locking claw to prevent the plug housing from loosening when the plug housing is inserted and mated with the socket. However, during frequent plugging and unplugging, the elasticity of the elastic locking claw gradually fails, the connection between the plug and the socket becomes loose, affecting their relative positions. When docking again, it is easy to cause damage to the terminals and reduce the service life of the connector.

[0004] Therefore, it is necessary to develop an anti-collision connector to solve the above problems. Summary of the Utility Model
