Embodiment

As shown in Fig. 1-6, a kind of isolating switch, comprise lid, pedestal 2, the standard guide rails assembling parking lamp 1 of pedestal 2 bottoms, junction block 3, fixed contact 4, contact supporter 5, moving contact bridge 51 and handle operation mechanism, described moving contact bridge 51 adopts Direct Action Type double-breakpoint structure, two ends at moving contact bridge 51 are provided with two silver main contacts 53, during large electric current, adopt two groups of parallel contact bridges in parallel, during little electric current, can only arrange one group, on the top of moving contact bridge 51, Stainless Steel spring leaf 52 is set simultaneously, be installed on together with moving contact bridge on contact supporter 5, described contact supporter 5 is the rectangular body of plastics, top arranges top shoulder 57 and projection 54, there are two through holes 55 centre, 56, in order to moving contact bridge 51 and Stainless Steel spring leaf 52 to be installed, described handle operation mechanism comprises operating grip 7 and energy-stored spring 6, the middle part of described operating grip 7 is fulcrum, propping up dot center is quincunx through hole 71, for the strong hole of the multipole assembling pin of isolating switch, outer circumferential edge at the strong Kong Erduan of pin is two round boss 72, in order to operating grip 7 is installed on the base and cover of isolating switch, in the lower end, top of operating grip 7, an end hole 75 is set, first half in operating grip 7 middle part one sides has groove 73, the latter half of convex shoulder 74 that arranges, when operating grip 7 is pushed to close a floodgate side, groove 73 contacts the top 53 of contact supporters 5 and contact supporter 5 is pressed down so that moving contact 53 passes through stainless steel spring sheet 52 and close contact with fixed contact 4, when pushing open position to, operating grip 7 carries on by the projection 54 on convex shoulder 74 contact contact supporters, so that moving contact 53 and fixed contact 4 are separately, further arrange, described energy-stored spring 6 is torsion type structure, one end hangs and is connected in the end hole 75 of handle, the other end is installed on pedestal cinclides 22, when operating grip 7 is pushed a side to, the energy storage effect that can utilize energy-stored spring 6 is by under contact supporter acceleration pressure or promote, to realize the quick break-make of dynamic/static contact, described fixed contact 4 is set to upper and lower two contact, one end 41 is installed on pedestal, when dynamic/static contact two moving contacts and tight pressing of fixed contact during in closing position, when dynamic/static contact during in open position because the insulation isolation 21 on pedestal makes dynamic/static contact can not touch and close, within the line ball end 42 of fixed contact 4 is sleeved on junction block 3, on the top of junction block 3, crimping screw hole is set, by regulating crimping screw, due to stopping of inner fixed contact line ball end 42, by carrying on junction block 3, make to be connect wire and clamp between fixed contact and junction block, described pedestal 2 and cover and deciliter locate to be provided with arc-chute 23 at dynamic/static contact, be conducive to the disjunction of load current, especially, above isolating switch is designed to conventional 18mm unit construction, if while needing two utmost points or multipole isolating switch, only the isolating switch of 2 or many unit constructions need be combined.

The beneficial effect that above structure is brought is: the guillotine type structure of traditional isolating switch is set to the two moving dot structures of Direct Action Type, the angular displacement of handle is changed into the displacement of the lines of contact by contact supporter, in addition the ingenious application of energy-stored spring, more accelerated moving contact and fixed contact of isolating switch deciliter, also the speed that makes artificial control crank deciliter is had no effect to isolating switch, special construction due to junction block and inner fixed contact terminals, make to be connect wire clamped by regulating crimping screw, because isolating switch pedestal bottom is provided with installation groove and the parking lamp of standard guide rail, making isolating switch can pacify quickly and easily loading or unloading is placed on standard guide rail, owing to adopting modularization mechanism, can be combined into easily two utmost points or multipole isolating switch.
