Abstract

The utility model relates to an integrate circuit relay, which is composed of a winding, an iron core, a magnetic yoke, an armature iron, a pair of static contacts, a moving contact, a base and a casing. The winding is buckled on the magnetic yoke and is welded on the magnetic yoke by the iron core, the moving contact is a switching leaf spring, and the prebuckling segment in the middle of the moving contact is contacted with a touch bridge. The utility model has the advantages of stable work and high reliability. The contacts have self cleaning function.

Description

Integrate circuit relay

The utility model relates to the relay field, particularly a kind of relay that is used for integrated circuit.

The existing integrated circuits relay is that iron core is inserted in the coil rack, the afterbody and the yoke of iron core is riveted again, the armature of relay in the process of adhesive, release, continuous striking iron core, iron core can become flexible gradually, cause the relay job insecurity, even lost efficacy.And the moving contact of existing relay is driven by spring, and the complicated reliability of mechanism is low, does not have self-cleaning function, and oxide-film that forms on the contact or the dust that accumulates can directly influence the performance of conducting, make relay work undesired.

The purpose of this utility model is to overcome the weak point of above-mentioned technology, and a kind of improved contact system and magnetic system, working stability, integrated circuit relay that reliability is high are provided.

The purpose of this utility model is achieved by the following technical solution: the integrated circuit relay is made up of coil, iron core, yoke, armature, fixed contact, moving contact, base and cover shell, core ends is a convex, iron core passes coil, coil is closely buckled on the yoke, and iron core and yoke welding; And moving contact itself is the conversion reed of a prebuckling, and its head is a contact, and afterbody embeds in the groove of pedestal, and the stage casing sweep contacts with the end of touching bridge.Like this, iron core, coil, yoke three's firm engagement can stand the striking of armature and loosening together for a long time.Simultaneously, the conversion reed has replaced spring, and a member is finished distortion and two functions of break-make, make the relay construction compactness, touch bridge and prop up in the bending section of conversion reed, when touching bridge and being subjected to the armature effect to promote the conversion reed, the deformation process of conversion reed is crooked--stretching--back-flexing.Thereby the contact between moving contact and the fixed contact, to separate be one to have the process of translation friction, can scrape off dust on the contact or oxide-film, avoided the influence to reliability of contact of dust and oxide-film.

The utility model is compared with original integrated circuit relay, has following advantage:

1, magnetic system is integrally welded, and the suction-combining force is more even.

2, compact conformation, working stability.

3, utilize the deformation characteristic of conversion reed, improved the conducting reliability of contact.

4, applied range.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the electrical schematic diagram of contact.

Below in conjunction with drawings and Examples the utility model is further elaborated.

With reference to Fig. 1, present embodiment mainly comprises magnetic system, contact system, pedestal 10 and lid shell 11.Iron core passes coil 1, and the convex 2 of core ends is closely buckled in coil 1 on the yoke 3, and iron core and yoke 3 welding, and armature 4 constitutes magnetic system with yoke 3.Moving contact itself is the conversion reed 8 of a prebuckling, and its head is that contact, afterbody embed in the groove 12 of pedestal 10, and the stage casing sweep contacts with the end of touching bridge 6, and they and fixed contact constitute contact system to 7,9.Each part of magnetic system and contact system is embedded in respectively in the pedestal 10.

During relay power, magnetic force makes armature 4 and 2 adhesives of iron core convex, armature 4 is that an angle has been rotated in the axle center with yoke 3 fulcrums, its afterbody promotes to touch bridge 6 and moves, thereby make 8 actions of conversion reed, crooked conversion reed 8 stretches earlier and remakes back-flexing, and contact is disconnected with fixed contact 7 having under the situation of longitudinal sliding motion, connects (with reference to Fig. 2) with fixed contact 9 with the same manner then.

Present embodiment improves a little to iron core, adopts different magnetic materials, can make bistable state integrated circuit relay.
