The present application provides a nut assembly 100 for a connector that is comparable to the female end of a connector and that can be screwed into a threaded connection with the male end of the connector, i.e., the locking assembly 200.

The nut assembly 100 mainly includes a screw 10 and a first plug member 20, the screw 10 being a member for achieving mounting fixation, and the first plug member 20 being a member for achieving electrical connection.

The assembly of the nut component 100 has a direction limitation, the first insert piece 20 is inserted into the screw element 10 along the first direction X, the outer part of the first insert piece 20 is provided with a limit stop 201, and the inner part of the screw element 10 is provided with a support step 101 for supporting the limit stop 201. The first direction X is the X direction shown in fig. 1.

Wherein, support step 101 and be provided with first tooth 1011, spacing platform 201 is provided with second tooth 2011, the profile of tooth meshing of first tooth 1011 and second tooth 2011. When the supporting step 101 and the limiting table 201 are pressed in the first direction X, the engaged first tooth 1011 and second tooth 2011 play a role in preventing loosening.

In addition, the first plug member 20 is provided with an internal thread 102, and the internal thread 102 functions as a screw connection with the locking assembly 200. The locking assembly 200 may have various structures, and it is within the scope of the present embodiment that the locking assembly has an external thread.

During use of the nut component 100 of the connector, the nut component 100 is connected with the locking component 200, and the locking component 200 is screwed into the internal thread 102 of the screw element 10 along the first direction X; under the action of the threads, the locking assembly 200 is locked with the nut assembly 100, and the limiting table 201 is pressed on the supporting step 101 by the locking assembly 200; at this time, the first tooth 1011 and the second tooth 2011 which are engaged prevent the screw 10 and the first plug member 20 from loosening, so that tooth locking is added on the basis of thread locking, and the situation that the screw is not easy to loosen after being installed in place is ensured.

In some embodiments, while effecting the screwing of the nut assembly 100 and the locking assembly 200, the locking assembly 200 is held stationary and the nut assembly 100 and the locking assembly 200 are screwed by rotating the nut assembly 100.
