The tradition knife switch generally includes ceramic wafer (seat); handle; contact knife; the contact knife support; the inlet wire connector assembly; outlet connector assembly and protective cover; the inlet wire connector assembly; the outlet wiring group is separately fixed at the two ends of ceramic wafer; the contact knife support is fixed on the ceramic wafer middle part; contact knife is hinged on the contact knife frame for one section; the contact knife frame bottom is fixed on the ceramic wafer middle part; contact knife one end is hinged on the contact knife support; the contact knife frame bottom is by the screw lug plate; the outlet connector assembly comprises on lug plate and the lug plate; the cross section is the lead fastening frame that the degree of lip-rounding is provided with housing pin; the inlet wire connector assembly comprises the lead fastening frame; the contact that brace and cross section are triangular in shape substantially and the top clamps; the connection of the inlet wire connector assembly of this knife switch is firm inadequately; easy loose or dislocation of long duration; cause great potential safety hazard for production and use; in addition, it is also firmly convenient inadequately with being connected of circumscripted power line.
Summary of the invention
The purpose of this utility model is to provide a kind of knife switch to advance the contact syndeton, the mechanical structure that this knife switch advances the contact syndeton is simple, manufacturing and installation procedure are few, the contact-making surface of hinged place is big, resistance is little during conduction of current, is difficult for heating, stability and safety more during work, and being connected firmly of itself and external connection, reliably, fast, have high use value.
The technical solution of the utility model is that a kind of knife switch advances the contact syndeton, comprise insulator foot, it is characterized in that: described insulator foot is provided with L type electric connecting sheet, one end of described L type electric connecting sheet has the contact that advances of plug-in strip contact to be connected with upper articulation, describedly advance contact and be made of the U matrix that encases the corresponding side of L type electric connecting sheet from bottom to top and close up, the bottom of described U matrix through running through screw and being clipped in the handle of a knife between the U matrix upper end is hinged.
The other end of above-mentioned L type electric connecting sheet is external terminal and the U type conduit that is positioned at base, is with the rectangle lasso on the described external terminal, and described external terminal is passed the lock-screw realization of rectangle lasso top board and being connected of external connection through from top to bottom.
Above-mentioned base is provided with the bolt that is used for fixing L type electric connecting sheet and U matrix from bottom to top.
The middle part of above-mentioned L type electric connecting sheet is provided with the screw that is used to be fixed on the base, and described base offers the screwed hole that is used to screw in this screw on the relevant position.
The top of above-mentioned plug-in strip contact is to the both sides bending, described bend with between the male contact handle of its upside, be connected by screw.
Advantage of the present utility model is: the one, and mechanical structure is simple, manufacturing and installation procedure are few; The 2nd, the contact-making surface of each junction and hinged place is big, and resistance is little during conduction of current, is difficult for heating, stability and safety more during work; The 3rd, the acting in conjunction of the U type conduit by rectangle lasso, lock-screw and base makes being connected firmly of itself and external connection, reliably, fast.
