Moving contact guiding and fixing bracket

The utility model relates to a moving contact guiding and fixing bracket, which comprises an insulating rod, a box body, a box cover, and internal and external sealing rings, wherein both ends of the insulating rod are provided with connecting threads, upper and lower surfaces of the box body are provided with connecting tables, a connecting screw hole is formed in the central position of box body, arc-shaped connecting grooves surrounding the axis of the connecting screw hole are formed in the connecting table on the upper surface of the box body, a sealing groove is additionally arranged between the connecting grooves and the connecting screw hole, the connecting grooves are connected with the sealing ring through the sealing groove, the box cover is connected with the box body through connecting screws for accommodating a drying agent, the shapes and distribution positions of connecting blocks are matched with that of the connecting grooves of the box body, and the connecting threads at the top end of the insulating rod are connected with the connecting screw hole of the box body through the connecting table on the lower surface of the box body. The moving contact guiding and fixing bracket can prevent deformation of contact fingers caused by left-right swinging of an isolating switch and a grounding switch during up-down twitches, can prevent abnormal conductivity of contacts caused by condensation and oxidation of contact surfaces due to damp outdoor climate when the isolating switch and the grounding switch are not in use, and is conductive to improve the use stability and reliability of a solid insulated ring main unit.
