Abstract
The utility model discloses a relay, which comprises a framework (1), a yoke (2), an armature (3), a movable contact spring (4), two fixed contact springs (5), a movable contact (6) and two fixed contacts (7), wherein the movable contact (6) and the movable contact spring (4) are fixedly connected; the two fixed contacts (7) are respectively and fixedly connected with the two fixed contact springs (5); and a limiting device for an armature (3) is arranged on the framework (1). The limiting device on the relay can limit the positions of the armature and the movable contact spring, and ensure the complete fit of the fixed contacts and the movable contact, so that the relay has higher working reliability.
Description
Technical field
The utility model relates to a kind of electronic control device, specifically is a kind of relay.
Background technology
Existing relay comprises two static contact spring pieces, a movable contact spring, armature, skeleton, be wrapped in coil on the skeleton cylinder, be fixed on the yoke on the skeleton; One end and the yoke of described movable contact spring are affixed, and the middle part and the armature of described movable contact spring are affixed, and the other end of described movable contact spring is provided with moving contact; Be respectively equipped with first fixed contact and second fixed contact on described first static contact, second static contact spring piece; The described moving contact and first fixed contact or second fixed contact are fitted.Because armature is fixed on the movable contact spring, and since on this relay without any the device that limits movable contact spring, armature position, therefore, in the course of action of movable contact spring, be easy to swing, make moving contact contact not exclusively, thereby cause both loose contacts, cause the electric conductivity of contact to descend with fixed contact.Therefore, the functional reliability of existing relay is low.
The utility model content
The technical problems to be solved in the utility model is, overcomes the defective of above prior art, provides a kind of functional reliability high relay.
The technical solution of the utility model is, a kind of relay is provided, and described relay is made up of skeleton, yoke, armature, movable contact spring, two static contact spring pieces, moving contact and two fixed contacts, and described moving contact and movable contact spring are affixed; Described two fixed contacts are affixed with two static contact spring pieces respectively, and described skeleton is provided with the stopping means of armature.
After adopting above structure, the utility model compared with prior art has the following advantages:
The skeleton of the utility model relay is provided with the stopping means of armature, this stopping means can limit the position of armature, just define the position of movable contact spring, thereby in the process of movable contact spring action, owing to there has been the existence of stopping means to make armature and movable contact spring in course of action, be difficult for swing, so movable contact spring is complete with contacting of fixed contact, and both electric conductivities are guaranteed, thereby has guaranteed the functional reliability of relay.
As improvement, described stopping means is made up of two guide vane end stops, has reduced the manufacturing cost of relay simultaneously again in the vibration problems that solves armature and movable contact spring above-below direction.And described armature is provided with two relative and spacing inclined-planes that tilt to the armature inboard from left to right, thereby has solved the vibration problems of armature and movable contact spring left and right directions.
Description of drawings
Accompanying drawing is the structural representation of the utility model relay.
Shown in the figure 1, skeleton, 2, yoke, 3, armature, 4, movable contact spring, 5, static contact spring piece, 6, moving contact, 7, fixed contact, 8, guide vane end stop, 9, spacing inclined-plane, 10, coil.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
(static contact and fixed contact are cutd open in the accompanying drawing) as shown in drawings, a kind of relay of the utility model, described relay is made up of skeleton 1, yoke 2, armature 3, movable contact spring 4, two static contact spring pieces 5, a moving contact 6, two fixed contacts 7 and coil 10, and described coil 10 is wrapped on the iron prop body of skeleton 1; Described yoke 2 usefulness rivets are on skeleton 1; One end of described movable contact spring 4 and yoke 2 riveted joints, the middle part of described movable contact spring 4 and armature 3 riveted joints, the other end riveted joint of described movable contact spring 4 has moving contact 6; Described two fixed contacts 7 are riveted with two static contact spring pieces 5 respectively; Described two fixed contacts 7 are respectively first fixed contact and second fixed contact, and moving contact 6 pastes mutually with first fixed contact when coil 10 work, does not paste mutually with second fixed contact when coil 10 is not worked; The described moving contact and first fixed contact or the second fixed contact described skeleton 1 of fitting is provided with the stopping means of armature 3.
Described stopping means is made up of two guide vane end stops 8; Described armature 3 be provided with two relative and from left to right to the inboard spacing inclined-planes 9 that tilt of armature 3, two medial surfaces that described two guide vane end stops 8 are relative and the shape on described two spacing inclined-planes 9 match.Wherein yoke 2 is provided with a groove with armature 3 contact positions, and the contact position with yoke 2 of described armature 3 is provided with a projection, and projection is embedded in the groove.During work,, produce magnetic force when coil 10 energisings, inhale moving armature 3, because it is spacing that yoke 2 and two guide vane end stops 8 carry out armature 2 at the upper and lower, left and right of armature 2 four direction respectively, thus can be fully armature 2 and movable contact spring 4 are carried out spacing, thereby guaranteed the functional reliability of relay.
Below only be a specific embodiment of the present utility model, the riveted joint of lifting is above also welded, is spirally connected certainly etc., and the connected mode of yoke 2 and armature 3 can be hinged or the like, and these are all in protection range of the present utility model.
Claims (2)
1. relay, described relay is made up of skeleton (1), yoke (2), armature (3), movable contact spring (4), two static contact spring pieces (5), a moving contact (6) and two fixed contacts (7), and described moving contact (6) is affixed with movable contact spring (4); Described two fixed contacts (7) are affixed with two static contact spring pieces (5) respectively, it is characterized in that: described skeleton (1) is provided with the stopping means of armature (3).
2. relay according to claim 1 is characterized in that: described stopping means is made up of two guide vane end stops (8); Described armature (3) be provided with two relative and from left to right to the inboard spacing inclined-planes (9) that tilt of armature (3), two medial surfaces that described two guide vane end stops (8) are relative and the shape on described two spacing inclined-planes (9) match.
