Description

Relay with gear bits part

Technical field

It the utility model is related to a kind of relay with gear bits part.

Background technology

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 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 circumference Not limited location on direction, therefore, catch bar may occur to rotate on circumferencial direction during up and down motion, so as to cause The deflection on movable contact spring occurred level direction fixed with catch bar, in turn results in movable contact and can not be accurately aligned with stationary contact, It has impact on the reliability of relay.To ensure the accurate alignment of sound contact, people set two between movable contact spring and location-plate The individual power of returning spring, the both ends of movable contact spring are tensed to avoid movable contact spring from deflecting by returning power spring.

But copper scale caused by sound contact disjunction can sputter to the insulating boot side wall side of relay, and copper scale contact is exhausted It can rebound and beat after edge cover side wall and return power lower spring end, because copper scale has higher energy, can make to return power lower spring end and melt Change impaired, reduce the service life for returning power spring so that the reliability of relay is poor, service life is shorter.

The content of the invention

The purpose of this utility model is to provide a kind of height for being avoided that and returning that power spring is impaired, can extend relay service life Potential relay.

To achieve the above object, the utility model adopts the following technical scheme that：A kind of relay with gear bits part, including Yoke, the insulating boot being arranged on yoke, the insulating boot have been cooperatively formed for accommodating movable contact component and stationary contact with yoke The chamber of point component, the movable contact component include movable contact spring and movable contact, and the movable contact spring is fixed on catch bar upper end, described Catch bar lower end is located at below yoke, is provided between the movable contact spring and yoke and returns power spring, the power of the returning spring includes first Return power spring and second and return power spring, described first returns power spring upper end is connected with movable contact spring one end, and described second returns power spring Upper end is connected with the movable contact spring other end, and described first, which returns power lower spring end and second, returns power lower spring end and be connected with yoke, institute The radial sidewalls for stating insulating boot comprise at least the first side wall and second sidewall, and the first side wall is oppositely arranged with second sidewall, First movable contact and the first stationary contact the contact disjunction forms the electric arc of oriented enclosing part the first side wall arc blow-out, and described second is dynamic Contact and the contact disjunction of the second stationary contact form the electric arc of oriented enclosing part second sidewall arc blow-out, and the yoke upper end is prolonged upwardly Stretch so that formed with two gear bits parts, the gear bits part includes first gear bits part and second gear bits part, the first gear bits part is located at The first side wall and first return power spring between, second gear bits part be located at second sidewall and second return power spring between, and institute The height and position of gear bits part upper limb is stated higher than the height and position for returning power lower spring end lower edge.

By the setting gear bits part on the upside of yoke, kept off so as to rebound to beat after the copper scale touching insulating boot radial sidewalls of sputtering Consider to be worth doing on part, to avoid the copper scale of high temperature from directly being contacted with returning power spring, return power spring to avoid the copper scale of high temperature from melting, extend The service life of power spring is returned, then improves the service life of the utility model relay, while avoids returning power spring performance hair Changing, to ensure the anti-deflection of movable contact spring, to ensure the normal use of the utility model relay, to improve the utility model The use reliability of relay.Wherein, when side before and after magnet steel is arranged at insulating boot, the first side wall and the second sidepiece are positioned at insulation Cover left and right sides, two movable contacts or so are set.

Preferably, the both ends of the first gear bits part extend and formed with the first auxiliary stopper to second sidewall side, and Make section C-shaped in configuration of the first gear bits part along catch bar radial direction, the both ends of the second gear bits part are to the first side wall Side extends and formed with the second auxiliary stopper, and makes section C-shaped in configuration of the second gear bits part along catch bar radial direction, and first returns For power lower spring end between two the first auxiliary stoppers, second returns power lower spring end between two the second auxiliary stoppers.

By setting the gear of C-shaped to consider part to be worth doing to be protected to returning circumferential three sides of power spring, to avoid the copper scale with high temperature from connecing Touch and return power spring, while consider part to be worth doing compared with the gear for enclosing structure and use material less, and be easy to return the connection of power lower spring end and yoke.

Preferably, the yoke is raised formed with two yokes upwardly extended, the yoke projection outer rim shape with The insulating boot radial sidewalls inner edge shape is adapted, and two yoke projections are oppositely arranged.

Preferably, the yoke projection is respectively positioned on electric arc arc blow-out direction.

Yoke projection is applied not only to position insulating boot, and the positioning for being convenient to yoke and insulating boot is fixed, and works as each yoke When projection be may be contained within electric arc arc blow-out direction, the gap for being additionally operable to avoid electric arc between yoke and insulating boot is moved to insulation Cover outside, to avoid arc short circuit, so as to avoid relay from burning, and it is higher relay voltage is done.

The utility model, which has, is avoided that returning power spring is damaged, can extend the advantages of relay service life.
