[0057] The working principle of the embodiment of the present application is as follows: by pre-plugging the plug body 1 into the socket body 2, the docking terminal 21 on the socket body 2 is plugged into the terminal insertion hole 43 of the insulating cover 4, and the positioning plate 314 on the socket body 2 is plugged into the slide groove 13 on the plug body 1, and the control column 315 on the positioning plate 314 is plugged into the connection port 3114, so as to limit the plug body 1 in the vertical direction, and then the locking sleeve is pressed downward, so that the locking sleeve slides downward relative to the plug body 1, so that the control column 315 slides upward along the driving groove 3113, and the locking block 321 also slides upward relative to the locking sleeve in the avoidance groove 3112, so that the control column 315 pulls the locking sleeve to move in the direction of the socket body 2 through the driving groove 3113, so that the locking sleeve pushes the plug body 1 to move in the direction of the socket body 2, so that the wire terminal 11 on the plug body 1 is plugged into the docking terminal 21, so that the plug body 1 and the socket body 2 are electrically connected.

[0058] When the locking sleeve is not pressed down, the upper positioning block 312 is located at the lower end of the limiting hole 3111 on the locking sleeve, and the lower positioning block 313 is located below the locking sleeve. Then, as the locking sleeve is pressed downward, the locking sleeve slides downward relative to the plug body 1, so that the lower end of the limiting hole 3111 on the locking sleeve moves in the direction of the lower positioning block 313, so that the lower end of the locking sleeve contacts the guiding inclined surface of the lower positioning block 313, and passes over the end of the lower positioning block 313 along the guiding inclined surface, so that the lower positioning block 313 gradually moves into the limiting hole 3111.

[0059] Then, the locking block 321 is pressed, so that the locking block 321 drives the locking terminal 322 and the positioning protrusion 3211 to move toward the socket body 2, so that the locking terminal 322 is plugged into the short-circuit terminal 323, so that the locking terminal 322 simultaneously contacts the two short-circuit springs 3231, thereby short-circuiting the two short-circuit springs 3231, thereby generating a short-circuit signal, so that the external control system can judge that the locking terminal 322 has been plugged in place through the short-circuit signal. The specific short-circuit method and the judgment method of the external control system are the existing technology in the field, which will not be elaborated here.

[0064] Reference Fig.15 and Fig.17A push block 634 is fixedly mounted on the top wall of the lower fixed block 3116 on the side wall of the avoidance groove 3112 of the pressing sleeve 311 on the push plate 632. The cross section of the push block 634 is a right-angled trapezoid, and the length of the upper bottom plate of the right-angled trapezoid is less than the length of the lower bottom side of the right-angled trapezoid. The inclined surface of the push block 634 is located near the locking block 321, and the inclined surface of the push block 634 is used to abut against the bottom wall of the lower fixed block 3116. A return spring 635 is installed in the push groove, and one end of the return spring 635 is fixedly connected to the inner wall of the push groove, and the other end of the return spring 635 is fixedly connected to the side wall of one end of the push plate 632 located in the push groove. The elastic force of the return spring 635 is also less than the elastic force of the locking spring 613.

[0065] The working principle of the embodiment of the present application is as follows: in the initial position, the locking block 321 is not plugged into the plug body 1, the locking spring 613, the unlocking spring 623 and the reset spring 635 are all in a relaxed state, the pull plate 633 at the end of the push plate 632 is separated from the pull hook 3212, and the push block 634 on the push plate 632 is also located in the push groove on the plug body 1. After the plug body 1 is plugged into the socket body 2, the pressing sleeve 311 is pressed downward to compress the push spring 631 until the pressing sleeve 311 is pressed down into place, at which time the push spring 631 is in a compressed state, and the pressing sleeve 311 is also positioned under the action of the upper positioning block 312 and the lower positioning block 313.

[0066] The locking block 321 is then pressed to insert the locking block 321 into the plug body 1, so that the second positioning hook 612 on the locking block 321 moves toward the direction of the first positioning hook 611 until the positioning protrusion 3211 on the locking block 321 is engaged with the limiting groove 3117, thereby completing the positioning connection between the locking block 321 and the pressing sleeve 311. At this time, after the second inclined surface on the second positioning hook 612 conflicts with the first inclined surface on the first positioning hook 611, the end of the second positioning hook 612 passes over the end of the first positioning hook 611 and is engaged with the first positioning hook 611, thereby further positioning the locking block 321 on the plug body 1, thereby facilitating further improving the firmness of the positioning of the locking block 321, thereby facilitating reducing the risk of the locking block 321 loosening due to vibration generated during the operation of the vehicle. At the same time, the guiding inclined surface at the end of the hook 3212 on the locking block 321 also contacts the end of the pull plate 633 and then engages with the pull groove 6331 on the pull plate 633 , thereby completing the positioning and installation of the locking block 321 .

[0067] When it is necessary to separate the plug body 1 from the socket body 2, the unlocking plate 621 on the locking block 321 is pressed, so that the unlocking plate 621 pushes the unlocking rod 622 to move in the direction of the second positioning hook 612 and compresses the unlocking spring 623, so that the end of the unlocking rod 622 contacts the side wall of the second positioning hook 612 and slides along the side wall of the second positioning hook 612, thereby pushing the second positioning hook 612 in the axial direction of the locking block 321, so that the second positioning hook 612 is elastically deformed, so that the second positioning hook 612 is separated from the first positioning hook 611, thereby unlocking the locking block 321 from the plug body 1, so that the locking block 321 can move in the direction away from the plug body 1 under the action of the locking spring 613, and drive the positioning protrusion 3211 to separate from the pressing sleeve 311, and then release the unlocking plate 621, so that the unlocking plate 621 is reset under the action of the unlocking spring 623, thereby completing the unlocking of the locking block 321.

[0068] When the locking spring 613 pushes the locking block 321 to move in the direction away from the plug body 1, the locking block 321 pulls the pulling plate 633 to move in the direction away from the plug body 1 through the pulling hook 3212, so that the pulling plate 633 drives the pushing plate 632 to move in the direction away from the plug body 1 and stretches the reset spring 635, so that the pushing plate 632 drives the pushing block 634 to move in the direction of the pressing sleeve 311, so that the inclined surface of the pushing block 634 contacts the bottom wall of the lower fixing block 3116 of the pressing sleeve 311, and the lower fixing block 3116 slides upward along the inclined surface of the pushing block 634, thereby pushing the pressing sleeve 311 upward, so that the lower positioning block 313 is staggered with the limiting hole 3111, thereby unlocking the pressing sleeve 311, so that the pressing sleeve 311 can be further pushed up under the action of the pushing spring 631, thereby facilitating the rapid separation of the plug body 1 and the socket body 2.

[0069] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
