In the present application, the direction in which the cable head is inserted into the clamping space is the second direction. Thus, in the present application, when a user needs to grip or release a cable plug, at least a portion of the driving assembly 30 may be controlled to move in the second direction, thereby moving the locking assembly 20 in the first direction to grip or release the cable plug. Therefore, the pre-tightening direction of the cable connector and the direction of the cable connector entering the cable connector are the same, so that the space of the connection cavity can be reduced, and the quick connection of the cable plug can be realized. Therefore, the cable lug in this application has solved the poor problem of cable plug equipment performance among the prior art effectively.
