Pass through technique scheme: the bearing on arc striking piece mainly plays the effect of fixing spring, prevent spring from contacting with the arc striking piece of metal material, play an insulating effect.In installation process, bearing is inserted by run-on tab, bearing is provided with fixture block, fixture block is provided with partition grooves, so just can play an elastic reaction, bearing first towards the deformation of partition grooves center, because elastic restoring force can be opened again after embedding through hole afterwards, thus can be fixed on arc striking piece by the fixture block snapping in first partition grooves both sides in the process of through hole at fixture block.Very effortlessly bearing can either be loaded like this, also can play the effect of close installation simultaneously.
The utility model is set to further: described bearing is provided with one end of spring contact and prevents spring from contacting annular table with run-on tab.
Pass through technique scheme: the area of annular table is larger, thus can ensure that spring directly can not contact with run-on tab, thus ensure that in the useful life producing spring in heat process, because heat sometimes can be collected on run-on tab, such spring is when being heated for a long time, spring can be made to anneal, softening spring, thus make spring failure.
The utility model is set to further: described fixture block is provided with the back-off fastened by run-on tab.
Pass through technique scheme: the setting of back-off, make back-off to rush across through hole, by bearing fastening on arc striking piece, this ensures that there the fixed effect of whole bearing and arc striking piece, ensure that the installation of spring.
The utility model is set to further: described bearing is round table-like.
Pass through technique scheme: by round table-like setting, the spring of various different size can be adapted to, facilitate type selecting.
The utility model is set to further: the draw-in groove described housing being provided with grafting run-on tab.
Pass through technique scheme: be arranged so that run-on tab can stablize installation on the main circuit by draw-in groove.
