Connector assembly, connector thereof, and connector housing

The invention relates to a connector assembly, a connector thereof, and a connector housing. A locking portion on a locking cap provides a pressing force by means of a pressing block on a cantilever buckle. Since the pressing block is disposed on the outer side surface of the cantilever buckle, the thickness of the cantilever buckle is unlimited and is set just based on the required elastic force.Thus, the cantilever buckle has appropriate deformation performance and a suitable elastic force, and solves the poor connection smoothness of the connector assembly caused by the poor deformation performance of the cantilever buckle of a conventional socket. The cooperation of the pressing block and the locking cap reduces the size of a mating surface so as to reduce the frictional force of thelocking cap moving in the front-rear direction, contribute to the movement of the locking cap in the front-rear direction and also improve the connection smoothness of the connector. 本发明涉及一种连接器组件及其连接器、连接器壳体。锁紧帽上的锁紧部通过悬臂卡扣上的压紧块
