Specifically, the shield cover 120 may be slidably coupled to the plug structure 110 in a direction perpendicular to the predetermined direction. The shield cover 120 has a through hole 121, and the lock lever 132 passes through the through hole 121 in an extended state. Specifically, the lock bar 132 passes through the through hole 121 in the process of extending along the preset direction, the lock bar 132 is kept in the extending state at this time, and the lock bar 132 abuts against the side wall of the through hole 121 at this time, and the shield cover 120 cannot slide along the vertical direction of the preset direction, so that the relative position relationship between the shield cover 120 and the plug structure 110 is fixed at this time, and the shield cover 120 is limited to the first state.

Specifically, the base 140 is used for fixing the position of the plug structure 110, and the base 140 may be configured as a box-shaped structure, and a portion of the plug structure 110 for being plugged by an external structure extends out of an outer surface of the base 140. The guide rod may also extend out of the outer surface of the base 140, and the guide rod may be integrated with the base 140 or may be fixedly connected to the base 140 by a fixed connection manner. For example, the guide rod may be a screw, and the base 140 may have a threaded hole, and the guide rod is fixedly connected to the base 140 by being screwed into the threaded hole. The shield case 120 has a guide groove 122, the guide groove 122 is closely spaced with the guide bar, the guide groove 122 may have a bar shape, and the guide groove 122 may extend in a vertical direction to the first direction, and in the case where the first direction is a horizontal direction, the guide groove 122 may extend in a vertical direction. The shield 120 is slidably coupled to the plug structure 110 by a base 140. Specifically, a gap is formed between the head of the screw and the outer surface of the base 140, and the gap can clamp the shield 120 such that the shield 120 can move only in a vertical direction.

The cooperation between the two guide rods and the two guide slots 122 can prevent the shield cover 120 from rotating relative to the guide rods, can limit the movement between the shield cover 120 and the plug structure 110 to only slide along the vertical direction, and can effectively ensure the stability of the movement of the shield cover 120 in the working state.
In some embodiments of the present application, the switch structure may be provided in plurality (e.g., may be provided in 2, 3, 4, 5, etc.). The control structure 130 is connected in parallel to all the switch structures. In this case, as long as one switch structure is in the on state, the control structure 130 is in the first state, which can ensure that the control structure 130 can be maintained in the second state only when all switch structures are in the off state, and at this time, the external structure can be plugged into the plug structure 110.
In some embodiments of the present application, the plug structure 110 is also provided in plurality, and the switch structure and the plug structure 110 correspond to each other one to one. Each switch structure controls the corresponding plug structure 110, and when all the switch structures are in the off state, the plug structures 110 are all in the power-off state, and in this state, the control structure 130 can keep the second state, and at this time, the external structure can be plugged in all the plug structures 110. As long as one plug structure 110 is in a powered state, other plug structures 110 cannot be plugged, so that the situation of live operation can be further prevented.
In some embodiments of the present application, in the first state, the protective cover 120 is at least partially located in the path of all the plug structures 110 to limit the insertion of the external structures into all the plug structures 110. That is, only one of the plug structures 110 needs to be in an electrified state, and all the plug structures 110 cannot be plugged by an external structure; only when all the plug structures 110 are in a power-off state, the plug structures 110 can be plugged by an external structure. In the second state, the protective cover 120 is completely outside the path of the external structure plugged in the plug structure 110, so that the external structure can be plugged in all the plug structures 110. Since all the plug structures 110 are in the power-off state in the second state, the external structure can be opened to plug in all the plug structures 110.
