[0041] As shown in Figure 2 , the handle 200 has a locking groove 210 corresponding to the locking dowel 21. The number of the locking grooves 210 corresponds to the number of the locking dowels 21. The operation of each locking dowel 21 and its corresponding locking groove 210 is the same, and only one of the locking dowels 21 and its corresponding locking groove 210 will be described below. The two ends of the locking groove 210 are an open end 211 and a locking end 212, respectively. Figure 3 ​​As shown, when the handle 200 is in the release position, the opening direction of the opening end 211 of the locking channel 210 is the same as the opening direction of the docking interface 101. When the docking connector 20 is docked to the docking interface 101, the locking tongue 21 is located in the corresponding locking channel 210. Specifically, when the handle 200 is in the release position, the docking connector 20 can be docked to the docking interface 101, and the locking tongue 21 can simultaneously enter the locking channel 210 through the opening end 211 of the corresponding locking channel 210.

[0042] Referring to Figure 3 When the handle 200 is in the release position, the opening end 211 of the locking channel 210 is closer to the docking interface 101 than the locking end 212, and the locking tongue 21 is located at the opening end 211 of the corresponding locking channel 210. Referring to Figure 7 When the handle 200 is in the release position, the opening direction of the opening end 211 of the locking channel 210 is the same as the opening direction of the docking interface 101. When the docking connector 20 is docked to the docking interface 101, the locking tongue 21 is located in the corresponding locking channel 210. Specifically, when the handle 200 is in the release position, the docking connector 20 can be docked to the docking interface 101, and the locking tongue 21 can simultaneously enter the locking channel 210 through the opening end 211 of the corresponding locking channel 210.

[0043] Referring to Figure 2 and Figure 3 The sleeve 300 is sleeved on the body 100 and can move parallel to the insertion direction 101a. The sleeve 300 includes at least one actuating channel 320, but the number of actuating channels 320 is not limited by the present application. The actuating channel 320 is not parallel to the insertion direction 101a. The two ends of the actuating channel 320 are an opening end 321 and a bottom end 322, respectively. The opening end 321 is closer to the docking interface 101 than the bottom end 322. The handle 200 has at least one actuating tongue 220 corresponding to the aforementioned actuating channel 320, but the number of actuating tongues 220 is not limited by the present application. The number of actuating tongues 220 corresponds to the number of actuating channels 320. Each actuating tongue 220 and its corresponding actuating channel 320 actuate in the same way. Hereinafter, only one actuating tongue 220 and its corresponding actuating channel 320 will be described as an example.

[0044] Referring to Figure 3 and Figure 4 During the rotation of the handle 200 to the locking position, the actuating tongue 220 can enter the actuating channel 320 through the opening end 321 of the corresponding actuating channel 320, and as Figure 7 shown, the actuating tongue 220 slides from the opening end 321 to the bottom end 322 of the corresponding actuating channel 320.

[0045] Referring to Figure 2The sliding sleeve 300 comprises a spring arm hook 330, when the actuating dowel 220 is slid along the actuating channel 320 as shown in Figure 3 Figure 4 the spring arm hook 330 can push the sliding sleeve 300 to move the spring arm hook 330 towards the positioning portion 102 as shown in Figure 5 to Figure 6 Figure 2 In particular, the spring arm hook 330 has a fulcrum 331 and a hook portion 332 disposed on one side of the fulcrum 331, and the spring arm hook 330 can swing about the fulcrum 331 to move the hook portion 332. Figure 5 to Figure 6 The positioning portion 102 can be any structure that can be hooked, in this embodiment, the positioning portion 102 is in the form of a protrusion, when the sliding sleeve 300 is pushed towards the positioning portion 102, the hook portion 332 passes through the positioning portion 102 and the spring arm hook 330 can swing to allow the hook portion 332 to be lifted (relative to the position of the positioning portion 102 on the outer surface of the body 100) to cross the positioning portion 102, and the hook portion 332 hooks the positioning portion 102. But the present application is not limited thereto, for example, the positioning portion 102 can also be in the form of a groove, the spring arm hook 330 pre-presses the hook portion 332 on the outer surface of the body 100, when the hook portion 332 passes through the positioning portion 102, it is pushed into the positioning portion 102 by the spring arm hook 330. The hook portion 332 hooks the positioning portion 102 to fix the sliding sleeve 300 to the body 100, thereby preventing the actuating dowel 220 from sliding along the actuating channel 320, and locking the rotating handle 200 to prevent the rotating handle 200 from rotating.

[0046] The spring arm hook 330 also has a pressing portion 333, and the hook portion 332 and the pressing portion 333 are oppositely disposed on both sides of the fulcrum 331. Figure 2 When the pressing portion 333 is pressed down, the spring arm hook 330 can rotate about the fulcrum 331 to lift the hook portion 332 (relative to the position of the positioning portion 102 on the outer surface of the body 100) to disengage from the positioning portion 102. Figure 9

[0047] When the user wants to separate the electrical connector 10 and the mating connector 20, the user first presses the pressing portion 333 to disengage the hook portion 332 from the positioning portion 102 to release the rotating handle 200. Then, the user can reverse the rotating handle 200 towards the release position to make the actuating dowel 220 exit the actuating channel 320 in the reverse direction and continue to rotate to the release position to make the opening direction of the opening end 211 of the locking channel 210 same as the opening direction of the insertion direction 101a, and the locking dowel 21 can exit the locking channel 210 through the opening end 211 of the locking channel 210 in parallel with the insertion direction 101a to allow the mating connector 20 to be detached from the electrical connector 10. Figure 9 to Figure 10

[0048] ​​​The electric connection assembly and the electric connector 10 thereof of the present application can sequentially lock the mating connector 20 and the rotating handle 200 by matching the sleeve 300 with the elastic arm catch 330 through the single locking action of rotating the handle 200, and when unlocking, the two-stage unlocking is required by sequentially operating the elastic arm catch 330 and the handle 200. Thus, the electric connection assembly and the electric connector 10 thereof are easy to lock and can avoid accidental unlocking.
