Abstract
The utility model relates to a kind of knife switch, comprise ceramic wafer (1), handle (2), contact knife (3), contact knife support (4), inlet wire connector assembly, outlet connector assembly and protective cover (5), its contact knife support (4) is structure as a whole with lug plate (6), by T font copper sheet with both wings in the same way mutually folding forms contact knife support (4), the centre of T font copper sheet vertically partly constitutes lug plate (6); Described contact (9) is similarly integrative-structure with brace (8), also by T font copper sheet both wings is rolled in the same way mutually to form contact (9), and the centre of T font copper sheet vertically part constitutes lug plate (6).Because contact knife support (4) is structure as a whole with brace (8) with lug plate (6), contact (9) in this programme, therefore the problem that does not have contact resistance, can adapt to, reduce number of parts simultaneously, make assembling convenient working long hours under the current conditions greatly.
Description
Technical field
The utility model relates to a kind of knife switch.
Background technology
Knife switch is modal separation or drop into the equipment of load in the present power circuit, uses very extensive.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; inlet wire connector assembly and outlet connector assembly are separately fixed at the ceramic wafer two ends; the contact knife support 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 connected with lug plate by screw; the outlet connector assembly comprises lug plate and is enclosed within on the lug plate; the cross section becomes the degree of lip-rounding to be provided with the lead fastening frame of housing pin; the inlet wire connector assembly comprises the lead fastening frame; brace and cross section are the △ shape substantially; the contact that open top elasticity clamps; lug plate wherein all is to connect by screw to compress with contact knife support and brace with being connected of contact; because lug plate can only accomplish that with the surface between contact knife support and the contact part contacts; contact resistance is bigger; therefore when big electric current flows through for a long time; will generate heat; and then cause fault to occur, influence ordinary production.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, easy to assembly, safe and reliable knife switch for overcoming the deficiencies in the prior art.
For achieving the above object, the technical scheme that the utility model adopted is as follows: a kind of knife switch, comprise ceramic wafer, handle, contact knife, contact knife support, inlet wire connector assembly, outlet connector assembly and protective cover, the outlet connector assembly comprises lug plate and is enclosed within lead fastening frame on the lug plate, the inlet wire connector assembly comprises lead fastening frame, brace and contact, it is characterized in that; Described contact knife support and lug plate are structure as a whole, and by T font copper sheet both wings are rolled in the same way mutually to form the contact knife support, and the centre of T font copper sheet vertically part constitutes lug plate; Described contact and brace are similarly integrative-structure, also by T font copper sheet both wings are rolled in the same way mutually to form the contact that open top elasticity clamps, and the centre of T font copper sheet vertically part constitutes brace.
Further improvement of the utility model: the plane that the opening part of described contact is relative is provided with the bow strip of relative protrusion, and described bow strip slightly tilts to the contact knife holder orientation, and is parallel with the contact knife of closing moment.
Compared with prior art, the beneficial effects of the utility model are: because contact knife support and lug plate, contact and brace are structure as a whole in this programme, therefore the problem that does not have contact resistance, can adapt under big current conditions and work long hours, reduced number of parts simultaneously, made assembling convenient.
The utility model is described in further detail below in conjunction with drawings and Examples.
