The current sensor 6 is arranged in the accommodating groove and is electrically connected with the abutting and pushing mechanism and the power-on module.

Specifically, in the process of using the socket, the electromagnetic push rod 4, the current sensor 6 and the power-on module are all electrically connected with an external power supply, and the external power supply supplies power to the current sensor 6 and the power-on module. The current sensor 6 is electrically connected to the power-on module, so that the current sensor 6 detects current fluctuation of the power-on module. When the plug is partially pulled out of the first plate 2 by pulling, the fluctuation of the current of the socket is large, and the current sensor 6 senses the fluctuation of the current. The current sensor 6 is electrically connected with the pushing mechanism, so that the pushing mechanism is started. When the pushing mechanism works, the output end of the electromagnetic push rod 4 of the pushing mechanism drives the bouncing component 5 to slide, the bouncing component 5 is switched to the ejection position from the avoidance position when the electromagnetic push rod 4 pushes, so that the driving plug is separated from the power-on module and the first plate 2, the power-on module and the power-on module are powered off, and the power-on equipment is prevented from being damaged by overlarge current fluctuation. When the plug passes through the first plate 2 to be electrically connected with the power-on module of the socket main body 1, the bouncing assembly 5 is in the avoiding position, so that the electrical connection between the plug and the socket is not affected. The specific structure and the working principle of the current sensor 6 and the electrical connection of the external power supply are the prior art, and are not described herein again.

Specifically, the socket further comprises a controller, the current sensor 6 is electrically connected with the electromagnetic push rod 4 through the controller, the current sensor 6 senses the fluctuation of current, whether the current fluctuation exceeds a preset range is judged through the controller, and if the current fluctuation exceeds the preset range, the output end of the electromagnetic push rod 4 is controlled to stretch out. The bouncing assembly 5 is connected to the output end of the electromagnetic push rod 4, so that the electromagnetic push rod 4 can drive the bouncing assembly 5 to be switched from the avoiding position to the ejecting position. In this embodiment, the controller may be centralized or distributed, for example, the controller may be a single-chip microcomputer or may be formed by a plurality of distributed single-chip microcomputers, and a control program may be run in the single-chip microcomputers to control the above-mentioned components to implement their functions.

The fixing ring 71 and the spacer 72 are provided with through holes for the pop-up assembly 5 to pass through, so that the pop-up assembly 5 can slide conveniently. When the pop-up assembly 5 is slid and switched to the eject position, one end of the pop-up assembly 5 close to the cylinder of the electromagnetic push rod 4 abuts against the gasket 72. The damping member 7 reduces the impact of the pop-up member 5 on the first plate 2. Specifically, the gasket 72 is a rubber gasket. The rubber gasket may protect the first plate 2 and the pop-up assembly 5 when the pop-up assembly 5 is slid to the pop-up position.
