Detailed description of the invention
Below in conjunction with Figure of description and embodiment, present invention is described in detail:
As shown in Figures 1 to 3, a kind of chopper is in transmission connection module, it is characterised in that: it includes by actuating
Mechanism 2 drive rotate main shaft 14, the connecting lever 13 be located on main shaft 14 and rotate with main shaft 14 and swing,
One end and connecting lever 13 are articulated and connected and are driven the insulated connecting rod 10 of motion and insulated connecting rod 10 by connecting lever 13
Transition connecting rod 8 and lower end that the other end is articulated and connected by the first connecting shaft 11 pass through second with transition connecting rod
Connecting shaft 7 is articulated and connected and the contact pressure being connected is fixed, with the moving conductive rod 5 of vacuum interrupter 1 lower end, in upper end
Power spring assembly 4；Described transition connecting rod 8 and contact pressure spring assembly 4 are located in lower wire outlet seat 3；Described
First connecting shaft 11 be respectively arranged at two ends with level in the horizontal guide groove 12 can only offered in lower wire outlet seat 3
The cross sliding clock 19 slided；Being respectively arranged at two ends with of described second connecting shaft 7 can only be opened in lower wire outlet seat 3
If vertical guide groove 9 in the vertical slide block 20 that slides up and down；Described contact pressure spring assembly 4 is at main shaft
Can move up and down and provide the assembly of closing pressure under 14 coordinated signals.
Described contact pressure spring assembly 4 includes the fixing guide rod 18, sheathed being connected of upper end and moving conductive rod 5
Outer in guide rod 18 and rely on the upper back-up ring 15 on guide rod 18 top, be sheathed on that guide rod 18 is outer and upper end relies on
Compression spring 6 on upper back-up ring 15, to be sheathed on guide rod 18 outer and rely on the lower back-up ring of compression spring 6 lower end
17 and be sheathed on that guide rod 18 is outer and upper end relies on the sleeve pipe 16 on lower back-up ring 17 lower surface；Described first
Connecting shaft 11 wears and is fixed on sleeve pipe 16；Described guide rod 18 is provided with accommodating first connecting shaft about 11 and transports
Dynamic elongated hole.
Described cross sliding clock 19, vertical slide block 20, horizontal guide groove 12 and vertical guide groove 9 all use high-tensile strength yellow
Copper is matrix, inlays graphite wherein as kollag, through particular manufacturing craft molding, processes.
For making insulated connecting rod 10 stress less, during combined floodgate, the axis of transition connecting rod 8 and insulated connecting rod 10
Axis is the angle of 70 °-80 °.
In specific implementation process, during combined floodgate, operating mechanism 2 controls main shaft 14 and rotates counterclockwise, main shaft 14
Drive insulated connecting rod 10 rearward movement by connecting lever 13, thus drive the connecting shaft 11 of insulated connecting rod 10 front end
Sliding backward in horizontal guide groove 12, and then drive sleeve pipe 16 to press up compression pressure by transition connecting rod 8
Spring 6, and promote upper back-up ring 15 by compression spring 6 and then drive guide rod 18 to be pushed up by moving conductive rod 5,
