Abstract: A connector plug usable to be connected to the connector socket in a fitting manner. The connector plug includes a housing component and an inner core component in the housing component. The housing component includes an inner housing and an outer housing movably sleeved at an outer side of the inner housing in an axial direction. A socket housing includes a socket locking mechanism, and a plug housing includes a corresponding plug locking mechanism usable to be connected to the socket to implement plug-socket locking, and an inner wall of the socket housing includes at least one socket anti-rotating structure in the axial direction, and a plug inner housing includes a matching plug anti-rotating structure usable to implement anti-rotation of the plug and the socket.
