Two ends of the actuating channel 320 are respectively an open end 321 and a bottom end 322 , and the open end 321 is closer to the docking port 101 than the bottom end 322 . The rotating handle 200 has at least one actuating tenon 220 corresponding to the aforementioned actuating channel 320 , but the present invention does not limit the number of the actuating tenon 220 , and the number of the actuating tenon 220 corresponds to the number of the actuating channel 320 . The cooperating action of each actuating tenon 220 and its corresponding actuating channel 320 is the same, and only one of the actuating tenons 220 and its corresponding actuating channel 320 will be described below as an example.

3 and 4, when the handle 200 is rotated to the locking position, the actuating tenon 220 can enter the actuating channel 320 through the opening end 321 of the corresponding actuating channel 320, as shown in FIG. 7 The actuating tenon 220 slides from the opening end 321 of the corresponding actuating channel 320 to the bottom end 322 .

Referring to FIG. 2, the sliding sleeve 300 includes an elastic arm hook 330, which can push the sliding sleeve 300 to make the elastic arm hook 330 when the actuating tenon 220 slides along the actuating channel 320 as shown in FIG. 3 and FIG. 5 to FIG. 6 to move toward the positioning part 102 to the hooking positioning part 102. Referring to FIG. 2 , specifically, the elastic arm hook 330 has a fulcrum 331 and a hook portion 332 disposed on one side of the fulcrum 331 , and the elastic arm hook 330 can swing along the fulcrum 331 to move the hook portion 332 . 5 to 6, the positioning part 102 can be any structure that can be buckled. In this embodiment, the positioning part 102 is in the form of a protrusion. When the sliding sleeve 300 is pushed toward the positioning part 102, the hook part 332 passes through the positioning part 102 and the elastic arm hook 330 can swing to allow the hook part 332 to be lifted by the positioning part 102 (relative to where the positioning part 102 is located on the outer surface of the body 100) to cross the positioning part 102, and the hook part 332 then hooks Connect to the positioning part 102. But the present invention is not limited thereto. For example, the positioning portion 102 can also be in the form of a groove.

Referring to FIG. 2 , the elastic arm hook 330 also has a pressing portion 333 , and the hook portion 332 and the pressing portion 333 are disposed on opposite sides of the fulcrum 331 . Referring to FIG. 9 , when the pressing part 333 is pressed down, the elastic arm hook 330 can be rotated around the fulcrum 331 to lift the hook part 332 (relative to where the positioning part 102 is located on the outer surface of the body 100 ) to leave the positioning part. 102.

Referring to FIGS. 9 to 10 , when the user wants to separate the electrical connector 10 from the docking joint 20 , the user first presses down the pressing portion 333 to disengage the hook portion 332 from the positioning portion 102 and release the handle 200 . Then, the user can reverse the turn handle 200 toward the release position so that the actuating tenon 220 backs out of the actuation channel 320 and continue to rotate to the release position so that the opening direction of the opening end 211 of the locking channel 210 and the opening direction of the docking port 101 are locked. In the same direction, the locking tenon 21 can exit the locking groove 210 through the opening end 211 of the locking groove 210 parallel to the insertion direction 101 a to allow the butt joint 20 to be detached from the electrical connector 10 .

The electrical connection assembly and its electrical connector 10 of the present invention can respectively lock the butt joint 20 and the rotating handle in a single locking action by rotating the rotating handle 200 through the rotating handle 200 cooperating with the sliding sleeve 300 with the elastic arm hook 330 200, and when unlocking, it is necessary to operate the elastic arm hook 330 and the rotating handle 200 in order to perform two-stage unlocking. In this way, the electrical connection assembly and its electrical connector 10 are easy to lock and can avoid unintended unlocking.
