Abstract
The utility model discloses an isolation switch contact structure, which comprises a moving contact and a static contact mutually matched. The moving contact comprises two contact sheets; an elastic sheet and a pressing sheet are arranged on the contact sheet; the elastic sheet is located between the contact sheet and the pressing sheet; the elastic sheet comprises a free part, a contact sheet fixing end and a pressing sheet fixing end; the free part is arranged in a wave type; the elastic sheet is in contact connection with the contact sheet via the contact sheet fixing end; and the other end, opposite to abutting connection with the contact sheet, of the elastic sheet is in abutting connection with the pressing sheet via the pressing sheet fixing end. According to the isolation switch contact structure, matching between the elastic sheet and the contact sheet is former, and the structure when the moving contact and the static contact are contacted is more stable.
Description
Technical field
The utility model relates to a kind of isolating switch accessory, and more particularly, it relates to a kind of switch touching header structure.
Background technology
Switch touching header structure generally comprises fixed contact and moving contact, described moving contact comprises the contact blade that two gaps arrange, described fixed contact can be chimeric and contact blade between and the thickness of described fixed contact be slightly larger than the gap between contact blade, on described each contact blade, be provided with flexure strip and clamping piece, described flexure strip is arch setting, in the time of in fixed contact is embedded in moving contact, between described contact blade because there is flexure strip, gap between contact blade is slightly squeezed and is opened by fixed contact, described flexure strip just can push clamping piece, clamping piece is fixedly installed on moving contact, by the interaction force between clamping piece and flexure strip, compress flexure strip, drive contact blade to compress fixed contact simultaneously, because flexure strip is arch setting, the stress point of arch is two ends of arch, lifting surface area is smaller, make the pressure of the formation between flexure strip and contact blade also smaller, cause moving contact can not firmly push down fixed contact and form stable structure, easily in use occur that contact is not firm, make isolating switch cisco unity malfunction.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of making to coordinate switch touching header structure more closely between flexure strip and contact blade, and while making the contact between moving contact and fixed contact, structure is more stable.
For achieving the above object, the utility model provides following technical scheme: a kind of switch touching header structure, the moving contact and the fixed contact that comprise mutual adaptation, described moving contact comprises two contact blades, on described contact blade, be provided with flexure strip and clamping piece, described flexure strip is between contact blade and clamping piece, described flexure strip comprises free portion, contact blade stiff end and clamping piece stiff end, described free portion is undaform setting, described flexure strip is connected with contact blade contact by contact blade stiff end, described flexure strip is conflicted and is connected with clamping piece by clamping piece stiff end with respect to the other end being connected with contact blade conflict.
By adopting technique scheme, the free portion of described flexure strip is undaform setting, in the time of moving contact and fixed contact cooperation, the free portion of undaform has increased the contact-making surface between flexure strip and moving contact, when making clamping piece compress flexure strip, between flexure strip and contact blade, form larger active force, guarantee the matching relationship of moving contact and fixed contact, make moving contact and fixed contact direct organization tightr.
The utility model is further set to: described free portion comprises several wave unit, the top of the waves of described each wave unit is all short-range horizontal plane setting, described clamping piece comprises the sticking part that is plane layout, the setting of mutually conflicting of described sticking part and free portion.
By adopting technique scheme, the top of the waves of each wave unit is all set to short-range horizontal plane, further increased the contact area of free portion and contact blade, and clamping piece is provided with the sticking part that is plane, improve the interaction force between clamping piece and flexure strip, further improved the active force between flexure strip and contact blade.
The utility model is further set to: described clamping piece stiff end is arranged at the center position of free portion, between described clamping piece and flexure strip, by screw bolt and nut, realizes adjustable cooperation.
By adopting technique scheme, adjusting nut can regulate the starting force between clamping piece and flexure strip, sets as required, improves this and leaves the practicality of closing structure of contact terminal.
The utility model is further set to: described sticking part two ends are provided with buckling parts, and the distance between described two buckling partss and the length of free portion are suitable.
By adopting technique scheme, the buckling parts of described both sides wraps up free portion, makes the structure of free portion compacter, has further improved the stability of the structure between clamping piece, flexure strip and contact blade.

Embodiment
Referring to figs. 1 through Fig. 2, the utility model switch touching header structure embodiment is described further.
A kind of switch touching header structure, the moving contact 2 and the fixed contact 1 that comprise mutual adaptation, described moving contact 2 comprises two contact blades 21, on described contact blade 21, be provided with flexure strip 5 and clamping piece 6, described flexure strip 5 is between contact blade 21 and clamping piece 6, described flexure strip 5 comprises free portion 51, contact blade stiff end 53 and clamping piece stiff end 52, described free portion 51 is undaform setting, described flexure strip 5 is connected with contact blade 21 contacts by contact blade stiff end 53, described flexure strip 5 is conflicted and is connected with clamping piece 6 by clamping piece stiff end 52 with respect to the other end being connected with contact blade 21 conflicts.
By adopting technique scheme, the free portion 51 of described flexure strip 5 is undaform setting, in the time of moving contact 2 and fixed contact 1 cooperation, the free portion 51 of undaform has increased the contact-making surface between flexure strip 5 and moving contact 2, when making clamping piece 6 compress flexure strip 5, between flexure strip 5 and contact blade 21, form larger active force, guarantee the matching relationship of moving contact 2 and fixed contact 1, make moving contact 2 and fixed contact 1 direct organization tightr.
Described free portion 51 comprises several wave unit, and the top of the waves of described each wave unit is all short-range horizontal plane setting, and described clamping piece 6 comprises the sticking part 61 that is plane layout, and described sticking part 61 is mutually conflicted and arranged with free portion 51.
