By fixing hole cam body 1 is connected with the rotation axis of shunting switch, the flange I is connected with the device contact of the opening and closing of vacuum interrupter with the flange II, when flange I and flange II contact with the device of the opening and closing of vacuum interrupter respectively, the device that flange I and flange II promote the opening and closing of vacuum interrupter respectively moves, vacuum interrupter is opened, when flange I and flange II do not contact with the device of the opening and closing of vacuum interrupter respectively, the device that flange I and flange II do not promote the opening and closing of vacuum interrupter respectively moves, vacuum interrupter is closed, owing to designed flange I and flange II, the direction of the power of the device of the opening and closing of promotion vacuum interrupter is identical with the cam body radial direction, cam body is moved at axis direction, improve the stability of the device of the opening and closing that promote vacuum interrupter, therefore improved the stability of the performance of vacuum interrupter.
The utility model has designed, and it is along cam body plane radially that two sides up and down of flange I and flange II are set to respectively, and flange I and flange II are set to its inboard width respectively less than outside width.Make its waveform corresponding with shunting switch.
The utility model has designed, and the flange I is set to connect with the flange II by connection rib.
The utility model has designed, and is provided with lug on the top of flange II, and the lug of flange II is provided with through hole.
The utility model has designed, and the side of cam body is provided with markings, and the markings of cam body are set to triangle.Make things convenient for the installation of cam body.
Four, description of drawings
Accompanying drawing is a schematic diagram of the present utility model.
Five, embodiment
Accompanying drawing is an embodiment of the present utility model, specify present embodiment in conjunction with the accompanying drawings, include cam body 1, cam body 1 is set to annular, the madial wall of cam body 1 is provided with flange I 14 and flange II 15, flange I 14 and flange II 15 are set to be arranged above and below on the madial wall of cam body 1, the medial surface of flange I 14 and flange II 15 is set to respectively connect with the device contact of the opening and closing of vacuum interrupter, flange I 14 is set to connect with flange II 15 by connection rib, the sidewall of cam body 1 is provided with fixing hole 17, and the side of cam body 1 is provided with markings.
In the present embodiment, it is along cam body 1 plane radially that two sides up and down of flange I 14 and flange II 15 are set to respectively, flange I 14 and flange II 15 are set to its inboard width respectively less than outside width, flange I 14 and flange II 15 are set to ten respectively, ten flange I 14 and flange II 15 are set to respectively be evenly distributed on the circumference, and it is corresponding that flange I 14 and flange II 15 are set to compartment.
In the present embodiment, be provided with lug on the top of flange II 15, the lug of flange II 15 is provided with through hole.
In the present embodiment, the markings of cam body 1 are set to triangle.
Normal line on the rotation axis of the markings of cam body 1 and shunting switch is aligned, cam body 1 is connected with the rotation axis of shunting switch by fixing hole 17 with bolt, flange I 14 is connected with the device contact of the opening and closing of vacuum interrupter with flange II 15, when flange I 14 and flange II 15 contact with the device of the opening and closing of vacuum interrupter respectively, the device that flange I 14 and flange II 15 promote the opening and closing of vacuum interrupter respectively moves, vacuum interrupter is opened, when flange I 14 and flange II 15 do not contact with the device of the opening and closing of vacuum interrupter respectively, the device that flange I 14 and flange II 15 do not promote the opening and closing of vacuum interrupter respectively moves, and vacuum interrupter is closed.
