The plug mechanism includes a plug housing 1, a plug high-current terminal 2, and a plug end cover 3. The plug housing 1 and The plug end caps 3 are circumferentially movable and axially limited and matched, the plug high current terminal 2 is fixedly arranged in the plug housing 1, and the socket mechanism includes the socket housing 4 and the socket high current terminal fixedly arranged in the socket housing 4. 5.

Mating socket high voltage interlock terminal 7.

The plug housing 1 is provided with a locking structure for circumferential movement and axial locking with the socket housing 4 .

The specific implementation process and principle description:

When the plug mechanism and the socket mechanism are inserted into each other, the circumferential locking structure is first aligned, and then the axial crimping is performed after the alignment. The high-voltage interlock terminal 6 is connected with the socket high-voltage interlock terminal 7 correspondingly.

Then, the plug housing 1 and the socket housing 4 are connected in circumferential movement and axial locking through the locking mechanism, at this time, the plug housing 1 and the socket housing 4 are axially locked.

At this time, the plug housing 1 can freely rotate relative to the plug end cover 3 in the circumferential direction, so as to satisfy any rotation angle adjustment between the plug housing 1 and the socket housing 4 .

Due to the design of the circumferential locking structure, the high-voltage interlock terminal 6 of the plug and the high-voltage interlock terminal 7 of the socket maintain the axial alignment requirement. When the plug shell 1 is rotated, the end cover 3 of the plug does not deflect arbitrarily, maintaining the high-voltage interlock terminal. The tight fitting of 6 has no relative displacement limit.

In a specific embodiment, as shown in FIG. 2 and FIG. 3 , the circumferential locking structure includes a plurality of axial locking grooves 8 arranged on the outer periphery of the plug end cover 3 , and a locking slot 8 arranged in the mating hole of the socket shell 4 . The locking ribs 9 are arranged in a one-to-one correspondence with the position slots 8 .

That is, when the plug mechanism and the socket mechanism are mated, the locking groove 8 and the locking rib body 9 are axially aligned to meet the alignment requirements of the plug end cover 3 passing through the mating hole of the socket shell 4. Ensure that the plug high voltage interlock terminal 6 and the socket high voltage interlock terminal 7 are relatively matched, and the lock slot 8 and the lock rib 9 cooperate to meet the circumferential locking requirement between the plug end cover 3 and the socket shell 4 .

In cooperation, the axial locking between the plug housing 1 and the socket housing 4 is realized, and the arc-shaped clip edge 13 is provided with a circumferential rotational displacement in the inner concave locking ring 12 .

In an optimal embodiment, the locking structure includes a locking key 14 for locking the locking clip 10 , and the locking key 14 is perpendicular to the mating direction of the locking clip 10 .

That is, after the locking clip 10 is locked, the locking clip 10 is locked in the plug housing 1 by inserting the locking key 14 to prevent the locking clip 10 from loosening. Certainly, there are some specific buckle structures between the locking key 14 , the locking fastener 10 and the plug housing 1 , which belong to the conventional tenon-and-mortise joint structure, and are not repeated here.

In a specific embodiment, the plug housing 1 is provided with a tubular seat 15 for mating with the plug end cover 3, the inner wall of the pipe of the tubular seat 15 is provided with a ring clip 16, and the plug end cover 3 is provided with a tubular seat for mating.
