The second retaining ring 240 is provided on the inner wall of the mounting bracket 200 to realize the fixed installation of the first insulating inner core 320.

[0037] Referring to Figure 4 , in a second aspect, an embodiment of a connector socket is proposed, which includes a socket body 900 and a socket tube assembly 2000; the socket body 900 includes a second plug end 910 and a tail end 920. A through hole 911 is provided on the second plug end 910, and a ball 1000 is installed in the through hole 911. The ball 1000 rolls in the through hole 911 and does not fall out; the socket tube assembly 2000 is installed in the socket body 900, and at least three balls 1000 are used.

[0038] To ensure that the pin terminal 310 can be accurately inserted into the socket terminal 2100 when the plug and the socket are plugged in, a positioning groove 912 is provided on the inner wall of the second plug end 910.

[0039] The socket body 900 further includes a horizontal plate 930, and a reinforcing ring 940 is provided at the junction of the horizontal plate 930 and the second plug end 910.

[0040] Referring to Figure 5 As shown, the socket tube assembly 2000 includes socket terminals 2100 and a second insulating inner core 2200. At least two socket terminals 2100 are used, and the number of socket terminals 2100 is matched with the number of pin terminals 310. The socket terminals 2100 are arranged and inserted on the second insulating inner core 2200.

[0041] Referring to Figures 6 to 8 As shown, in a third aspect, an embodiment of a connector is proposed, which includes a plug and a socket. The plug adopts a connector plug proposed in the first aspect embodiment, and the socket adopts a connector socket proposed in the second aspect embodiment.

[0042] Referring to Figure 9As shown, when using the connection, the plug body 100 is opposed to the socket body 900, and the positioning bump 230 faces the positioning groove 912. Then, the first insertion end portion 110 is pushed into the second insertion end portion 910, so that the pin terminal 310 is accurately inserted into the socket terminal 2100, realizing a quick push-in connection and reducing the requirement for the operating space.

[0043] Referring to Figure 8 As shown, simultaneously during the process of inserting the pin terminal 310 into the socket terminal 2100, the ball 1000 will be extruded outward by the first insertion end portion 110, causing the ball 1000 to protrude outward and pushing the locking ring 400 to move in the direction of the inlet end portion 120. At this time, the spring 500 is in a compressed state. When the ball 1000 enters the locking groove ring 210, the ball 1000 is no longer extruded by the first insertion end portion 110, so that the ball 1000 no longer protrudes outward. The locking ring 400 will reset under the action of the spring 500 and move to the outside of the ball 1000 and completely abut against the ball 1000, causing the ball 1000 to be pressed tightly in the locking groove ring 210, so that the plug and the socket form a locked state after the insertion is completed, preventing loosening and disconnection between the plug and the socket and improving the stability of the equipment power supply.

[0044] When unlocking, the locking ring 400 is pushed in the direction of the inlet end portion 120 to release the pressing of the locking ring 400 on the ball 1000, so that the ball 1000 can roll out of the locking groove ring 210 again. At this time, the plug and the socket can be directly pulled out and disassembled.
