Part, in structure is enclosed, described first, which returns power lower spring end and second, returns power spring in section of the gear bits part along catch bar radial direction
Lower end is respectively positioned on the inside of the gear bits part, and the height and position of the gear bits part upper limb returns power lower spring end lower edge higher than described
Height and position.
By being provided with gear bits part on the upside of location-plate, beaten so as to be rebounded after the copper scale touching insulating boot inner radial wall of sputtering
On gear bits part, to avoid the copper scale of high temperature from directly being contacted with returning power spring, power spring is returned to avoid the copper scale of high temperature from melting, is extended
The service life of power spring is returned, then improves the service life of the utility model relay, while avoids returning power spring performance
Change, it is new to improve this practicality to ensure the normal use of the utility model relay to ensure the anti-deflection of movable contact spring
The use reliability of type relay.
Preferably, the quantity of the gear bits part is two, described first returns power lower spring end, second returns power lower spring end
Respectively on the inside of a gear bits part.
Preferably, the quantity of the gear bits part is one, described first returns power lower spring end, second returns power lower spring end
It is respectively positioned on the inside of the gear bits part.
Preferably, the location-plate is integrally formed, location-plate projection raised formed with two location-plates upwardly extended
Outer rim shape is adapted with insulating boot inner radial wall inner edge shape, and two location-plate projections are oppositely arranged, and each location-plate is convex
Rise and may be contained within electric arc arc blow-out direction.Location-plate projection is applied not only to position insulating boot, is convenient to location-plate and insulating boot
Assembling, and when each location-plate projection may be contained within electric arc arc blow-out direction, it is additionally operable to avoid electric arc from location-plate and insulation
Gap between cover is moved on the outside of insulating boot, to avoid arc short circuit, so as to avoid relay from burning, and makes relay voltage
What can be done is higher.
Preferably, the insulating boot, location-plate and yoke are each formed with the through hole run through up and down, in the through hole
Be combined with bolt, the through hole after the screw bolt passes insulating boot, location-plate with yoke is screwed, or the bolt according to
Secondary to be fixed through insulating boot, location-plate, after yoke with nut thread, the bolt thread fixation by location-plate to be limited in insulation
Between cover and yoke.It is screwed by bolt with yoke or nut thread is fixed, location-plate is limited in yoke and insulation
Between cover.
The utility model, which has, is avoided that returning power spring is damaged, can extend the advantages of relay service life.
