Description
Technical field
The utility model relates to the device for switching that uses in a kind of electric device, and especially a kind of auxiliary switch (having another name called universal seclector or cam switch) that is used for electric control loop belongs to technical field of electric appliances.
Background technology
In automatic control and field of power electronics, auxiliary switch is applied to the control of electric equipment widely, raising along with automaticity, just require auxiliary switch can realize more function, the number of plies of auxiliary switch is just more and more, and wiring becomes increasingly complex, existing auxiliary switch is flat bed structure, two-way line ball mostly, need during wiring to carry out line ball at the both direction up and down of auxiliary switch, its shortcoming is an inconvenient operation, and wiring efficient is low.For fear of this defective, recently on the market a kind of unidirectional line ball has appearred again, and the auxiliary switch of staggered floor construction is board-like pressuring line structure but it adopts, and thickness is too big again, and the weak point of board-like pressuring line structure is to need prefabricated leads, its wiring cost height before the wiring; The shortcoming that thickness is too big is the number of plies that has seriously limited auxiliary switch, can't do manyly on the number of plies, has significantly reduced the function of auxiliary switch.
Summary of the invention
In order to solve the prior art above shortcomings, the utility model proposes that a kind of thickness is ultra-thin, the splitlevel auxiliary switch of unidirectional line ball, this auxiliary switch comprises rotating shaft, cover plate, connecting bolt, pull bar and multilayer contact assembly, each layer contact assembly comprises contact box, movable contact spring, movable contact bar, static contact, spring, termination and cam, its contact box adopts the splitlevel structure, termination adopts the frame wiring construction, and thin thickness of the present utility model, volume is little, the number of plies is many; Folk prescription is to line ball, and is easy to operate, wiring efficient height.
The utility model solves its technical problem, the technical scheme that is adopted is: a kind of splitlevel auxiliary switch, comprise rotating shaft, cover plate, connecting bolt, pull bar and multilayer contact assembly, each layer contact assembly comprises contact box, movable contact spring, movable contact bar, static contact, spring, termination and cam, its design feature is: contact box is divided into upper and lower two wiring layers, its upper and lower layer adopts the splitlevel structure, upper strata wiring hole and lower floor's wiring hole be not in same plane, the half storey position of having staggered, simultaneously up and down two laminated yarn holes towards identical; Termination adopts the frame wiring construction, comprises pressing line frame and screw.
Above-mentioned splitlevel auxiliary switch, an end of its static contact penetrates in the wiring hole of pressing line frame, the position relative fixed of static contact, pressing line frame is lifting with the rotation of screw, and the lifting by pressing line frame is crimped on lead and static contact together.
Above-mentioned splitlevel auxiliary switch, be provided with reference column and connecting hole in the front of contact box, be provided with location hole and joint pin at the back side of contact box, the reference column in upper layer of contact box front can insert in the location hole at the lower layer of contact box back side, the joint pin at the lower layer of contact box back side can also insert in the connecting hole in upper layer of contact box front, by reference column and joint pin the integral body that connects into of multilayer contact box compactness.
Compared with prior art, the beneficial effects of the utility model are: contact box of the present utility model is divided into upper and lower two wiring layers, its upper and lower layer adopts the splitlevel structure, upper strata wiring hole and lower floor's wiring hole be not in same plane, the half storey position of having staggered, its beneficial effect is to make upper and lower two-layer wiring mutually noninterfere, and the lead that the upper strata is inserted can not cover the line ball hole of lower floor, makes things convenient for the wiring operation.Simultaneously the upper and lower two laminated yarn holes of contact box towards identical, its beneficial effect is all wiring operations that only need finishing on the same direction on the multilayer auxiliary switch, its operating efficiency height; Prior art then must be operated respectively on former and later two directions, could finish the wiring of auxiliary switch jointly, and its operating efficiency is low.Termination of the present utility model in addition adopts line ball frame wiring construction, its beneficial effect is the thickness that closed-in construction can reduce every contact box greatly, compared with prior art, thickness of the present utility model has only half of existing auxiliary switch, under the situation of equal length, about the number of plies of the present utility model can double,, increased the number of plies and the function of auxiliary switch so the utility model has dwindled the volume of auxiliary switch.
