An anti-loosening electrical connector

Abstract

The utility model discloses an anti-loosening electrical connector, including an electrical connector body and a connector head, wherein the connector head is plugged into the interior of the electrical connector body, and mounting blocks are fixed to both ends of the connector head. In the process of connecting the connector head with the electrical connector body, the connector head passes through the interior of the dustproof seat, and the connecting block is inserted into the connecting groove. During the deep penetration of the connecting block, its trapezoidal surface contacts the locking pin and causes it to enter the accommodating groove. When the connecting block and the connecting groove are engaged, the spring pushes the locking pin to reset and connect with the locking groove, thus realizing the automatic locking function of the connector head, thereby making it difficult for the electrical connector body and the connector head to loosen due to external factors, thus ensuring the connection stability. Further pushing the lever outward can drive the locking pin to separate from the locking groove, thus canceling the locking, and the operation is simple and convenient to use.
