for achieving the above object, the utility model provides following technical scheme: a kind of main circuit switch, comprise jack shell and plug, described plug is fixedly connected with described jack shell by steady pin, described plug is fixed on by plug copper bar and inserted sheet and forms an independently integral body in the plug fixture block, described inserted sheet is symmetrical arranged in pairs, described paired and symmetrically arranged inserted sheet is by the clamping of contact buckle, two of described inserted sheet has two and supports shoulder, supporting between shoulder of inserted sheet two is provided with spring pressuring plate, described inserted sheet, spring pressuring plate is fixing in the draw-in groove of described plug fixture block by the touch spring mounting board, the end of described inserted sheet in described plug fixture block is connected with described plug copper bar.
By adopting technique scheme, this main circuit switch has improved the anti-fatigue performance of spring, patches more reliably, and structure is more firm, has improved the mechanical flexibility in the assembling process.
The utility model further is set to, and described inserted sheet is two stacked and middle gaps of leaving.
By adopting technique scheme, improved the heat dispersion of plug, temperature rise is lower, inserted sheet is pegged graft more stable.
The utility model further is set to, and described jack shell is extended baffle plate in inserted sheet one side.
By adopting technique scheme, prevent that inserted sheet from being clashed in patching process, also prevented from producing electric arc between plug simultaneously, cause fault.
The utility model further is set to, and on described jack shell, the quantity of plug slot is at least one.
By adopting technique scheme, the moving plug-in unit of main circuit can arrange one or more plug slot according to demand, facilitates practical application.
The utility model further is set to, and the paired symmetrically arranged inserted sheet of one deck is set in described plug at least.
By adopting technique scheme, inserted sheet paired in plug can be arranged to one deck, also can be arranged to multilayer, increases the stability and the contact area that patch in process.
