Abstract
The utility model provides a time difference shunt electric switch which comprises a movable electrical conductor and a fixed electrical conductor. The main contacts are arranged on the movable electrical conductor and the fixed electrical conductor correspondingly. The movable electrical conductor and the fixed electrical conductor are correspondingly provided with a couple of high temperature resistant auxiliary contact points, and the space of the auxiliary contact points is smaller than the space of the main contacts. During energization, the high temperature resistant auxiliary contact points are switched on and then the main contact is switched on for realizing the energization with time difference, power cut, and parallel shunting action. The arc only acts on the auxiliary contact points, and the main contact can not be damaged, sintered, and stuck by the arc. The utility model has the advantages of simple structure, reliable performance, more switching times and long service life.
Description
The utility model provides a kind of time difference shunting appliance switch, belongs to contact appliance switch field.
At present, the contact appliance switch all adopts metal material copper or that conductance reaches more than 95% to do the contact, and its advantage is the conductance height, and shortcoming is that fusing point is low, all below 1100 ℃, thereby the electric arc (instantaneous temperature reaches more than 1500 ℃) that produces during often by frequent switching electricity hits damage.If adopt fusing point to do the contact at the metal material more than 3000 ℃, though be difficult for being hit damage by electric arc, its conductance can produce a large amount of heat energy all below 30%, all can not do the contact separately and use.
The purpose of this utility model provides frequently power on/off, is difficult for being hit damage, sintering and sticking connection by break-make electric arc, and the life-span is long, the time difference shunting appliance switch that performance is good.
The purpose of this utility model is achieved in that
Comprise the moving conductive body and decide electric conductor, moving, as decide correspondence on the electric conductor main contacts that is provided with, move, decide to go back on the electric conductor corresponding high temperature resistant, the wear-resistant auxiliary contact that are provided with, the spacing of auxiliary contact is less than the main contacts spacing, and the auxiliary contact on the moving conductive body can move up and down with respect to the moving conductive body.
Described time difference shunting appliance switch is established a jack on the moving conductive body, auxilliary some contact is set with spring, passes jack and is fixed on the moving conductive body by the nut slip.
Described time difference shunting appliance switch, auxiliary contact establish a lead by the fixing end of nut and moving conductive sports association connects.
The purpose of this utility model also can realize in the following way:
Comprise the moving conductive body and decide electric conductor, moving, decide the corresponding main contacts that is provided with on the electric conductor, moving, decide to go back on the electric conductor parallel connection and be provided with high temperature resistant, the wear-resistant auxiliary contact identical with the main contacts structure, and the spacing of auxiliary contact is less than the main contacts spacing.
The utility model compared with prior art; time difference energising, time difference outage and shunting in parallel have been realized because of having adopted main and auxiliary contact; thereby protected main contacts to be difficult for being hit damage, sintering and sticking connection by electric arc; high temperature resistant because of the auxiliary contact employing again, anti-abrasive material is made; so long service life, dependable performance, and utilize auxiliary contact; can save the expensive silver material that main contacts is used, cost obviously reduces.
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Fig. 2 is the structural representation of the another kind of embodiment of the utility model.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Among Fig. 1, moving conductive body 1 and decide electric conductor 4 and connect power line respectively, and corresponding main contacts 2 and the main contacts 3 of being provided with, decide also to establish on the electric conductor 4 high temperature resistant auxiliary contact 11, corresponding to the auxiliary contact of deciding on the electric conductor 4 11, establish a jack 8 on the moving conductive body 1, the cylinder 5 that has high temperature resistant auxiliary contact 10 is set with spring 9, pass jack 8 and be fixed on the moving conductive body 1, and the spacing of auxiliary contact 10 and auxiliary contact 11 is less than the spacing of main contacts 2 and main contacts 3 by nut 6.Cylinder 5 by the fixing ends of nut 6 also establish-lead 7 connects with moving conductive body 1.
Among Fig. 2, the two ends of pressing plate 1 are fixed with column 2 and column 3, and column 2 and column 3 are with stage clip 4 respectively, corresponding pass and slide be fixed on the moving conductive body 5 that is provided with a pair of main contacts 7 and be provided with on the moving conductive body 6 of a pair of auxiliary contact 8.Decide electric conductor 11 and decide to be respectively equipped with on the electric conductor 12 main contacts 9 and auxiliary contact 10, corresponding with main contacts, auxiliary contact on the moving conductive body, and move, decide the spacing of electric conductor auxiliary contact less than the main contacts spacing.
When energized, at first two auxiliary contact contact, energized, main contacts contact then, energized increases to normally electric current gradually; During outage, main contacts is deenergization at first, and auxiliary contact are deenergization in succession again.Make main contacts and auxiliary contact-elder generation-back realize time difference energising, time difference outage and shunting in parallel like this, thereby guaranteed that main contacts is difficult for being hit damage, sintering and sticking connection by electric arc.This utility model can be widely used in all appliance switches such as various model AC/DC contactor, air switch, compensating switch, flame-proof switch.
