Description
Technical field
The present invention relates to a kind of high-voltage relay.
Background technology
Relay can produce some chips in assembling, and the disjunction of sound contact can produce some copper to relay when in use
Bits, these debris are all sealed in insulating boot and in the chamber of yoke formation, debris can be moved between catch bar and yoke
In gap so that be obstructed when catch bar is moved up and down, or even stuck catch bar so that sound contact can not in time contact or divide
It is disconnected, influence the using effect of relay.
In high-voltage relay, dynamic iron core can drive catch bar to move up and down, so as to be fixed on the movable contact spring of catch bar upper end
On movable contact contact or separate with stationary contact.In the prior art, catch bar only has and is oriented in the axial direction, and catch bar is justified
Not limited location in circumferential direction, therefore, catch bar may occur to rotate on circumferencial direction during up and down motion, so as to make
Deflection on the movable contact spring occurred level direction fixed with catch bar, in turn resulting in movable contact can not be accurately right with stationary contact
Standard, have impact on the reliability of relay.To ensure the accurate alignment of sound contact, people are set between movable contact spring and location-plate
Two are returned power spring, are tensed the two ends of movable contact spring by returning power spring to avoid movable contact spring from deflecting.
But the copper scale produced during sound contact disjunction can be sputtered to the insulating boot side wall side of relay, and copper scale contact is exhausted
It can rebound and beat after the wall of edge cover side and return power lower spring end, because copper scale has higher energy, can make to return power lower spring end and melt
Change impaired, the service life of power spring is returned in reduction so that the reliability of relay is poor, service life is shorter.Wherein, due to weight
The reason for power, copper scale can always be moved down, and high temperature copper scale can only make to return power lower spring end and be damaged.
The content of the invention
It is avoided that catch bar is stuck, it is smooth to ensure that catch bar moves up and down it is an object of the invention to provide one kind, and can keeps away
Exempt to return the high-voltage relay that power spring is damaged, extends relay service life.
To achieve the above object, the present invention is adopted the following technical scheme that：A kind of high-voltage relay, including yoke, be arranged at
Stationary contact component and movable contact component above yoke, the stationary contact component include exit and stationary contact, the movable contact
Component includes movable contact spring and movable contact, and movable contact spring is mutually fixed with catch bar upper end, and catch bar lower end is located at below yoke, the yoke
Be provided with location-plate and insulating boot on the upside of iron, the insulating boot with the yoke fixation be formed be used to accommodating movable contact component and
The chamber of stationary contact component, the insulating boot includes top plate and enclosing part, and the top plate is used to fix stationary contact component, described fixed
Position plate is formed with the location-plate through hole for running through pass through for catch bar up and down, and it is convex that the location-plate is formed with the protection upwardly extended
Rise, the protection projection is in enclose structure along the section of catch bar radial direction, and the location-plate through hole is raised positioned at the protection
Inner side.
The present invention is raised in the protection for enclosing structure by being formed with location-plate, circumferentially to be protected to catch bar
Shield, stops, it is to avoid debris is moved in the gap between yoke and catch bar to debris, is pushed away with ensureing that dynamic iron core can drive
Lever is swimmingly moved up and down, and avoids catch bar stuck, to ensure the performance of invention relay, greatly promotes this hair
The reliability of bright relay.
