Compared with prior art, the present invention has the advantage that as follows with effect: patent of the present invention uses slide block assembling to move up and down along axis of guide direction and presses microswitch, realize the break-make of microswitch contact, solve traditional F-C loop auxiliary contact few, structure is complicated, standardization level is low, bulky problem, solve the problem of mutually insulated between vacuum contactor-fuse combined electric appliance back contact that is assembled into simultaneously, and microswitch assembling takes up room little in the circuit board, any one contact goes wrong and can independently change, maintenance cost is low and highly versatile.
Four, accompanying drawing explanation:
Fig. 1 is the schematic cross-section of the present invention；
Fig. 2 is the axonometric chart of the present invention；
1 fixed plate；2 slide block assemblings；3 axis of guides；4 back-moving springs；5 wiring board assemblings；6 depression bars, 7 microswitch, 8 slide blocks, 9 wiring boards, 10 M4 screwed holes；11 M6 screwed holes.
Five, detailed description of the invention:
The present invention is described in detail with detailed description of the invention below in conjunction with the accompanying drawings:
nullSee Fig. 1 and Fig. 2: a kind of special auxiliary switch of vacuum contactor-fuse combined electric appliance，The framework formed by screw including two fixed plates be arrangeding in parallel 1 and two wiring boards be arrangeding in parallel 9，The bottom of described framework is provided with base plate，Relative microswitch 7 it is respectively welded on described wiring board 9，Described base plate be provided centrally with step column type axis of guide installing hole，The axis of guide 3 it is provided with in installing hole，The axis of guide 3 upper end is arranged with slide block 8，Before and after described slide block 8, face contacts with the tabletting of microswitch 7，Face, left and right is arranged with 1mm gap in parallel with two fixed plates be arrangeding in parallel 1 respectively，The provided circumferentially about of the described axis of guide 3 times 2/3rds has back-moving spring 4，It is provided with depression bar 6 on two side slides 8 of the axis of guide 3，One end of depression bar 6 stretches out in slide block 8，One end of depression bar 6 is connected by screwed hole with slide block 8；Slide block 8 moves up and down along the axis of guide 3 direction, and the electric shock pressing microswitch 7 completes switching of getting an electric shock.
The screwed hole 11 of two M6 it is provided with on described base plate.
The screwed hole 10 being radially arranged two M6 of described step post.
In the present invention, microswitch 7 is welded on wiring board 9, and this assembly of microswitch 7 and wiring board 9 composition is wiring board assembling 5；2 wiring board assemblings 5 are fixed on fixed plate both sides with the screw of M4 respectively, microswitch 7 is welded on wiring board 9, the quantity unrestricted choice of microswitch, and all of contact is internal all in microswitch encapsulation, improve the insulating properties between contact, have good arc quenching effect.
Depression bar 6 is fixed on slide block 8, and its length can freely regulate, such that it is able to the stroke of regulation microswitch, slide block 8 is a part for slide block assembling 2, slide block assembling 2 is made up of slide block 8 and depression bar 6, and depression bar 6 is connected on slide block 8 by screwed hole, composition slide block assembling 2.
Slide block 8 and back-moving spring 4 are arranged on the axis of guide 3, and the axis of guide 3 is arranged on the correspondence position of fixed plate 1, and slide block 8 turns the centre position joining 5 just at wiring board, and can fully press all contacts of microswitch 7.When vacuum contactor-fuse combined electric appliance closes a floodgate, fixed plate 1 carries out spacing, the driving plate of combined electrical apparatus provides driving force, now slide block assembling 2 moves downward along the direction of the axis of guide 3 under the effect of driving force, press the microswitch 7 in the wiring board assembling 5 being fixed on fixed plate both sides, realize the break-make switching of microswitch, give back-moving spring energy storage simultaneously.When vacuum contactor-fuse combined electric appliance separating brake, the back-moving spring 4 of energy storage provide driving force, make slide block 8 move upward along the axis of guide 3, make microswitch 7 reset, reach the break-make switching of microswitch.This structural module, contact is reliable and stable, and volume is little, it is simple to keeps in repair and changes, and composition vacuum contactor fuse combined electric apparatus is more reliable and more stable.
The screwed hole 11 of 2 M6 is arranged at fixed plate 1 bottom, and auxiliary switch parts are connected with the installing plate in combined electrical apparatus by the hexagon socket head cap screw of M6.Plate is driven to directly bear against on depression bar during assembling, it is not necessary to the conversion of power, unreliable factor is few.
The present invention solves that traditional F-C loop auxiliary contact are few, volume is big, action is unreliable, the problem of inconvenient regulation, simultaneously modular construction take up room little, be conveniently replaceable, need not the debugging of complexity, highly versatile.Making product more stable after being assembled into vacuum contactor or vacuum contactor-fuse combined electric appliance, performance is relatively reliable.
