Background technology
The word explanation of switch is opening and closing.It refers to that one can make open circuit, make current interruptions or make it
Flow to the element of other circuits.It is most common switch be allow people operate electromechanical equipment, wherein there are one or several contacts.Contact
" closed " (closed) represent contact conducting, allow electric current flow through；" open circuit " (open) of switch represents that contact is not turned on shape
Into open circuit, electric current is not allowed to flow through.The developing history of switch is developed to from the original knife switch for needing manual hand manipulation
The present intelligent switch applied in various large electric control devices, the function of switch is more and more, and security is also got over
Come higher, rotary switch is a kind of common switch, by the way that rotary operator to be locked in the spy with rotary operating device
The corresponding specific position of state is determined rotary operating device to be prevented to be operated without permission.Rotary isolation switch is widely applied
In electric system, for example, photovoltaic, wind-powered electricity generation etc..Such as in photovoltaic system, the smaller electric current that is generated in each photovoltaic cell
It is combined that the system of utilizing is given to provide required electric current or general power in parallel.
In existing photovoltaic system, usually individually isolate, protect and disconnect each light using rotary isolation switch realization
Lie prostrate the purpose of battery.At present, be commonly used in photovoltaic system rotary separation switch include an operating mechanism and it is several touch
The structures shape of head module, wherein contact module the arc quenching effect of disconnecting switch, and existing contact module is rotatably being isolated
Switch moving contact component and static contact component engagement or disengage when can generate electric arc electric discharge, if electric arc cannot quickly extinguish or
Rotary separation switch is left, the interrupting performance of rotary separation switch will be reduced, causes the generation of security incident.It is dynamic at present
Contact assembly includes revolving part and both ends movable contact spring corresponding with the static contact component respectively, and conventional revolving part is insulation
Part, movable contact spring are metalwork, and revolving part is split type two chip architecture, and when assembling needs movable contact spring is on chip with every rotation respectively
After preparing and then two panels revolving fragment is assembled up again, whole process is complicated, and electricity is climbed between moving contact component and static contact component
Apart from too small, the phenomenon that being easy to cause moving contact component and breakdown static contact component, occurs.
Utility model content
The purpose of this utility model is aiming at the insulated rotary piece of existing rotary separation switch moving contact component
Standard process is complicated, and the creepage distance between moving contact component and static contact component is too small to cause contact assembly and static contact group
The breakdown technological deficiency of part provides a kind of integral type moving contact revolving part of rotary separation switch, by moving contact revolving part
Formula is made of one, simplifies assembly difficulty, meanwhile, insulation moving contact revolving part is done into waviness, adds moving contact component
Creepage distance between static contact component avoids moving contact component and static contact component breakdown.
Technical solution
In order to realize above-mentioned technical purpose, the integral type moving contact rotation of the rotary separation switch of the utility model design
Part, it includes revolving part body, it is characterised in that：The revolving part body is an integral structure, the rotation of the integral structure
The disk for turning part body is waveform.
Further, the revolving part body is equipped with groove, and the bottom portion of groove is equipped with hole, and the revolving part body includes
Upper revolving and lower revolving are equipped with the accommodation space with static contact component cooperation between the upper revolving and lower revolving,
The disk of the upper revolving and lower revolving makes the width of accommodation space uneven for waveform.
Further, the correspondence position of the upper revolving and lower revolving is equipped with movable contact spring installation gap.
Preferably, the upper revolving and the corrugated lug boss of lower revolving disk correspond to rotary separation switch
Moving contact component and static contact component are in disjunction position.
Preferably, the revolving part body is insulating part.
Further, several locating parts are set in the groove, for fixing movable contact spring.
Advantageous effect
The integral type moving contact revolving part of a kind of rotary separation switch provided by the utility model, by moving contact revolving part
Formula is made of one, simplifies assembly difficulty, meanwhile, insulation moving contact revolving part is done into waviness, adds moving contact component
Creepage distance between static contact component avoids moving contact component and static contact component breakdown.
Description of the drawings
