Description

Large power integrate circuit relay

The utility model relates to the relay field, particularly a kind of high-power integrated circuit relay.

Existing integrated circuits relay, coil, iron core, yoke are riveted and fixed, and armature is continuous striking iron core in course of action, and after the long-term work, whole magnetic system can be become flexible, and causes the relay job insecurity, even loses efficacy.Contact does not have self-cleaning function, and the conduction property of oxide-film that forms on the contact or the dust that accumulates meeting influencing contactor makes the relay job insecurity.And general integrated circuit relay volume is less, thereby the overcurrent capability of its contact is also less, and proof voltage is low can not be directly in order to drive powerful power consumption equipment, and the scope of application is less.

The purpose of this utility model is to overcome the weak point of above-mentioned technology, provides a kind of by improving magnetic system and contact system, to improve the high-power integrated circuit relay that reliability, overcurrent capability also can directly drive heavy current installation.

The purpose of this utility model is achieved by the following technical solution: the high-power integrated circuit relay is made up of coil, iron core, yoke, armature, armature reed, fixed contact, moving contact, base and cover shell, core ends is a convex, iron core passes coil coil is held on the yoke, and welds with yoke; Like this, make iron core, coil, yoke three's firm engagement, can not do relative displacement, can stand the striking of armature for a long time and loosening.Moving contact is the conversion reed of a prebuckling, and its head is a contact, and the middle bent section contacts with the push rod end; Have only a conversion reed and fixed contact to form a pair of normally open contact and normally closed interlock respectively; The end face that yoke supports armature is the inclined-plane, contacts with the armature line.Simultaneously, the conversion reed makes the normally closed interlock closure with prebuckling power, under the promotion of push rod, the deformation process of conversion reed is crooked--stretching--back-flexing, thereby the joint between the contact, to separate be the course of action that has vertical friction, can scrape off dust on the contact and oxide-film, improve the reliable in action of relay.The utility model only is equipped with a pair of fixed contact, compares with the integrated circuit relay with volume, and contact is bigger, and touch panel is thicker, thus its to bear overcurrent capability stronger, adapt to the needs that drive large power-consuming equipment.

Compare with original integrated circuit relay, the utlity model has following advantage:

1, working stability, the reliability height.

2, little, the compact conformation of volume.

But the big electric current that 3 conductings are 16 amperes can directly drive powerful power consumption equipment.

4, applied range.

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

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 its end convex 2 is closely buckled in coil 1 on the yoke 3, and 3 welding of iron core and yoke, adds upper armature 4 and armature reed 5 constitutes magnetic system together.Moving contact itself is the conversion reed 8 of a prebuckling, and head is a contact, and the middle bent section contacts with push rod 6 ends, and conversion reed 8 constitutes contact system with fixed contact 7,9.Connected by push rod 6 between magnetic system and the contact system, armature reed 5 makes armature 4 location, and makes armature 4 be in indifferent equilibrium.

Present embodiment has only a pair of fixed contact 7,9, forms a pair of normally open contact, a pair of normally closed interlock respectively with conversion reed 8.General integrated circuit relay, about 0.5 square millimeter of the sectional area of its contact, touch panel, 1 ampere of maximum conveyance capacity, the sectional area of the conversion reed 8 of present embodiment and fixed contact 7,9 is 2.5 square millimeters, 16 amperes of maximum overcurrent.For making armature 4 rotate flexibility and reliability, an end face 12 of yoke 3 is designed to the inclined-plane, make it to form line and contact with armature 4.

When relay power is worked, armature 4 adhesives, armature 4 afterbodys promote push rod 6, make to have vertical friction between conversion reed 8 and the fixed contact 7 and disconnect, after again with the same manner and fixed contact 9 connections.Present embodiment improves a little to iron core, adopts different magnetic materials, can make bi-stable type integrated circuit relay.
