[0010] Furthermore, the limit clamping assembly also includes a spring and a limit plate, the inner side of the side plate is elastically connected to the limit plate through the spring, and two limit plates are symmetrically arranged about the vertical center line of the socket.

[0011] Furthermore, the rear plate is in an "L"-shaped structure, and the rear plate is rotatably connected to the rotating screw through a bearing, and the bottom of the rotating screw is rotatably connected to the socket.

[0012] Furthermore, the upper positioning plate is connected to the lifting plate via a T-shaped slider and a sliding groove, and the upper positioning plate cannot escape from the lifting plate.

The plug-in socket 4 with a "U"-shaped structure is convenient for protecting the front and rear sides of the switch housing 1. At the same time, the internal space of the plug-in socket 4 is relatively wide, so that there is a certain distance between the plug-in socket 4 and the rear side of the switch housing 1, which is convenient for ventilation and heat dissipation while facilitating wiring.

[0025] like Figure 1 and Figure 3 As shown, the limit clamping assembly 7 is installed on both sides of the switch housing 1, and the limit clamping assembly 7 includes a hinge 701 and a connecting block 702. The left and right sides of the rear inner wall of the switch housing 1 are rotatably connected with the connecting block 702 through the hinge 701.

[0026] The specific operation is as follows: the hinge 701 is used to easily rotate and open the connecting block 702 and the side plate 703, so that the limit clamping assembly 7 is opened to make room for the accommodating space during the installation process without affecting the normal insertion of the switch housing 1.
