Description

Technical Field

[0001] This utility model relates to the field of switchgear, and in particular to an integrated solid-sealed pole moving contact and isolating switch connection assembly. Background Technology

[0002] An isolating blade needs to be connected to one end of the solid-sealed terminal. In existing technology, an isolating bracket is set at the end of the solid-sealed terminal, and a conductive static bracket is fixedly mounted on the isolating bracket. The isolating blade is rotatably connected to the static bracket. One end of the flexible connector is fixedly connected to the connection between the static bracket and the isolating bracket, and the other end of the flexible connector is connected to the outlet socket of the solid-sealed terminal. The disadvantages of this connection structure of the isolating blade are that there are many parts connected to the isolating blade assembly, the circuit resistance is high, which affects its assembly efficiency and electrical performance. Moreover, there is rotational friction at the connection between the two copper plates of the isolating blade and the static bracket. Although there is a rotating shaft connection, gaps may be generated between the two, affecting its conductivity. Summary of the Invention

[0003] The purpose of this utility model is to address the problems of existing integrated solid-sealed pole moving contact and isolating switch connection components described in the background art, and to provide an integrated solid-sealed pole moving contact and isolating switch connection component that can solve the aforementioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an integrated solid-sealed pole moving contact and isolating switch connection assembly, comprising an isolating bracket, an isolating switch, and a flexible connection. The isolating switch has a connecting plate at its end, which is fixedly connected to one end of the flexible connection by bolts. The other end of the flexible connection is fixedly connected to the outlet seat of the solid-sealed pole. The isolating switch has a rotating shaft hole near its end, and the isolating switch is rotatably connected to the isolating bracket via a rotating shaft. Both ends of the rotating shaft are fixedly connected to the isolating bracket, and the middle part of the rotating shaft passes through the rotating shaft hole.

[0005] In the above scheme, the isolation bracket includes a front side plate, a rear side plate, a left side plate, and a right side plate. The front side plate and the rear side plate are fixedly connected to the connecting seat at the end of the insulating shell of the solid-sealed pole. The left side plate and the right side plate are fixedly connected to the left and right sides of the front side plate and the rear side plate, respectively. The front sides of the left side plate and the right side plate are fixedly connected to the front side plate, and the rear sides of the left side plate and the right side plate are fixedly connected to the rear side plate. This arrangement ensures the structural stability of the isolation bracket, allows the isolation blade to rotate flexibly and maintain a stable connection after direct connection with the isolation bracket, and also protects the outlet seat of the solid-sealed pole.

[0006] In the above scheme, the isolation bracket also includes an upper side plate, which is fixedly connected between the front side plate and the rear side plate and is located on top of the front side plate and the rear side plate. By setting the upper side plate, the structure of the isolation bracket can be made more stable, and the solidified terminal outlet seat at the end of the solidified terminal can be protected.

[0007] In the above solution, the isolation blade is connected to the right side of the isolation bracket, and the rotating shaft is fixedly connected to the front and rear side plates of the isolation bracket near the upper side plate. An opening is provided between the right side plate and the upper side plate, the size of which is adapted to the movement angle of the isolation blade and the flexible connection. This arrangement allows the isolation blade to move within the opening between the right side plate and the upper side plate, ensuring sufficient range of motion and limiting the rotation angle of the isolation blade. Simultaneously, the flexible connection can move synchronously with the isolation blade.

[0008] In the above scheme, the bottom of the front and rear side plates are respectively provided with connecting edges, and connecting holes are provided on the connecting edges. Connecting nuts are embedded in the connecting seats of the insulating shell. The front and rear side plates are respectively fixedly connected to the connecting seats at the ends of the sealing pole by bolts. By providing connecting edges, the connection between the front and rear side plates and the connecting seats of the insulating shell can be made more secure.

[0009] In the above scheme, protective plates are provided on the front and rear sides of the connecting seat at the end of the insulating shell of the solidified pole. By providing protective plates on the front and rear sides of the connecting seat at the end of the insulating shell of the solidified pole, the insulation protection of the isolation bracket can be strengthened.

[0010] This invention has several advantages: Firstly, the integrated solid-sealed pole moving contact and isolating switch connection assembly allows the isolating switch end to be directly and fixedly connected to the flexible connector via a connecting plate. The other end of the flexible connector is fixedly connected to the outlet seat of the solid-sealed pole. Furthermore, the connection between the isolating switch and the flexible connector remains stationary during rotation, resulting in better conductivity between the isolating switch and the flexible connector. Secondly, the static support is eliminated in the circuit structure, allowing current to flow directly from the isolating switch to the flexible connector, reducing loop resistance and minimizing the number of connecting components, thus improving assembly efficiency.
