There is striking pin, and tactile bridge one end stretches into left arc-chutes, the other end and stretches into right arc-chutes, is equipped with left arc-chutes and right arc-chutes
Some arc extinguishing grid pieces, are provided with run-on tab in arc-chutes, the run-on tab is designed for integral type, through left arc-chutes and right arc-chutes,
This easy phenomenon for producing string arc, and the easy scaling loss of striking pin, in addition, arc extinguishing grid pieces one end is provided with multiple arc ends, another
One end is smooth side, and smooth side is unfavorable for the striking of arc extinguishing grid pieces, and electric arc easily directly impinges upon smooth while upper (unfavorable while smooth
In the guiding of electric arc) so that arc quenching plate striking effect is poor.
The content of the invention
In view of the deficiency of background technology, technical problem to be solved in the utility model is to provide one kind and is difficult string arc, energy
Enough avoid the arc-control device of striking pin scaling loss and the more preferable electric switch of arc extinguishing grid pieces striking effect.
Therefore, the utility model adopts the following technical scheme that to realize：
The arc-control device of electric switch, including base and the multigroup arc-chutes in base, the arc-chutes are by left arc extinguishing
Room and right arc-chutes are constituted, and tactile bridge is provided between the left arc-chutes and right arc-chutes, and the two ends of the tactile bridge are provided with striking pin,
And tactile bridge one end stretches into left arc-chutes, the other end and stretches into right arc-chutes, it is characterized in that：In the left arc-chutes and right arc-chutes
Run-on tab and some arc extinguishing grid pieces are provided with, the run-on tab is located at arc extinguishing grid pieces lower section, and the front and rear both sides of run-on tab are equipped with
First partition, run-on tab is provided with the second partition near the side of tactile bridge, and second partition is located at and touches bridge lower section.
The second partition top is less than striking foot portion to the vertical range of arc extinguishing grid pieces to the vertical range for touching bridge.
Described arc extinguishing grid pieces one end is provided with multiple arc ends, the other end and is provided with protuberance.
After adopting the above technical scheme, left arc-chutes and right arc-chutes are all equipped with single run-on tab, run-on tab is provided with
First partition and the second partition, effectively prevent string arc, and the second partition top is less than striking foot to the vertical range for touching bridge
Portion can be prevented effectively from striking pin scaling loss to the vertical range of arc extinguishing grid pieces, in addition, arc extinguishing grid pieces one end is provided with protuberance, electricity
Arc enters from (front end) arc end, by being gone out from another arc end again after protuberance, striking be oriented to clearly facilitate and
Striking effect is more preferable.
