Abstract
The utility model relates to an auxiliary switch that vacuum contactor used, including insulation support, static contact, moving contact, linkage guide bar, reset spring and insulation cover plate, insulation cover plate install on insulation support, and form the cavity between the insulation support, install the several static contact on the insulation support in the cavity, reset spring is installed to partly gliding the stretching into of linkage guide bar behind the cavity, several longitudinal arrangement's moving contact is installed to the both sides of the linkage guide bar in the cavity, this moving contact with static contact movable fit installation, and one -to -one. The utility model has the advantages that: change area of contact and contact in the cavity to changed the contact material, from realizing the low -resistance value, area of contact is big, the high reliability, move stable characteristic.
Description
Technical field
This utility model relates to electric switch field, particularly relates to a kind of simple in construction, the auxiliary switch of practicality is good, reliability is high vacuum contactor.
Background technology
In vacuum contactor, it is desirable to provide the secondary status activation signal that reliability is stable, auxiliary switch is generally used to realize.
In the auxiliary switch of prior art, a kind of be contact mode be the auxiliary switch of plane, as it is shown in figure 1, its comprise edge support, plane static contact, plane moving contact, linkage guide post, back-moving spring, insulation cover plate can not solve loose contact problem, it is difficult to reliable and stable contact is provided.
To this end, designer of the present utility model is because drawbacks described above, by concentrating on studies and designing, comprehensive experience and the achievement being engaged in related industry for a long time for many years, research design goes out the auxiliary switch of a kind of arc contact, to overcome drawbacks described above.
Summary of the invention
Problem to be solved in the utility model be improve in prior art that auxiliary is not turned on, contact resistance is big, time the problem such as obstructed when leading to.
The technical solution of the utility model is: the auxiliary switch of a kind of vacuum contactor, including insulating support, static contact, moving contact, linkage guide post, back-moving spring and insulation cover plate, described insulation cover plate is arranged on insulating support, and forms cavity between insulating support；Being provided with several static contact on insulating support in cavity, be provided with back-moving spring after what a part for described linkage guide post was slided stretch to cavity, the both sides of the linkage guide post in cavity are provided with the moving contact of several longitudinal arrangement；This moving contact is dynamic with described static contact coordinates installation, and one_to_one corresponding.
The cooperation face of described static contact and moving contact is arcwall face.
The material of described static contact and moving contact is yellow gold.
The utility model has the advantages that: change contact area and the way of contact in cavity, and change contact material, from realizing low-resistance value, contact area is big, high reliability, stable feature.
Accompanying drawing explanation
Fig. 1 is agent structure schematic diagram of the present utility model；
Fig. 2 is enlarged drawing at the P of Fig. 1.
Detailed description of the invention
Further describe this utility model below in conjunction with specific embodiment, advantage of the present utility model and feature will be with describe and apparent.But these embodiments are only exemplary, scope of the present utility model is not constituted any restriction.It will be understood by those skilled in the art that and the details of technical solutions of the utility model and form can be modified or replace under without departing from spirit and scope of the present utility model, but these amendments and replacement each fall within protection domain of the present utility model.
See Fig. 1 and Fig. 2, this utility model relates to the auxiliary switch of a kind of vacuum contactor, including insulating support 1, static contact 2, moving contact 3, linkage guide post 4, back-moving spring 6 and insulation cover plate 5, described insulation cover plate 5 is arranged on insulating support 4, and forms cavity between insulating support 4；Being provided with several static contact 5 on insulating support 4 in cavity, be provided with back-moving spring 6 after what a part for described linkage guide post 4 was slided stretch to cavity, the both sides of the linkage guide post 4 in cavity are provided with the moving contact 3 of several longitudinal arrangement；This moving contact 3 is dynamic with described static contact 2 coordinates installation, and one_to_one corresponding.
The cooperation face of described static contact 2 and moving contact 3 is arcwall face, and size just one_to_one corresponding, and purpose increases contact area, can reduce contact resistance simultaneously, meets low-voltage, and small area analysis gathers signal.
The material of described static contact 2 and moving contact 3 is yellow gold, and the feature of yellow gold has good electric conductivity, wearability, resistance fusion welding, non-oxidizability, and these features improve the ability adapting to complex environment simultaneously, enhance the operational reliability of auxiliary switch.
Operation principle of the present utility model is, by increasing contact area to dynamic and static contact, reduces contact resistance value, simultaneously, the power of back-moving spring 5 acts on linkage guide post 4, and described linkage guide post 4 drives described moving contact 3 then to act on described static contact 2, it is achieved the on and off of contact.
The auxiliary switch of the vacuum contactor of the application, combines the principle of plane formula contact, in this internal change contact area of auxiliary switch and the way of contact, and changing contact material, from realizing low-resistance value, contact area is big, high reliability, stable feature.
