Description
Technical field
The utility model relates to a kind of relay, especially refers to a kind of small high-power relay that is used for occasions such as household electrical appliance, automated system, electronic equipment, instrument and meter, communication device and remote control.
Background technology
The structure of existing small high-power relay has presented various ways, as the Chinese patent publication number is that " small high-power relay " of CN201017824 just disclosed wherein a kind of structure, this relay comprises base, is positioned at contact system, magnetic circuit system and insulating cover and case on the base, wherein, magnetic circuit system includes coil, suture introducing needle, iron core, yoke and armature; Contact system comprises again often opens quiet contact chip, normally closed quiet contact chip and at the moving contacting plate of often opening between quiet contact chip and the normally closed quiet contact chip; Base is provided with the jack for the leading foot insertion of each contact chip, armature links by push rod and the moving contacting plate that is positioned at the insulating cover top, it is characterized in that insulating cover and base designs are integral part, and be the opening cavity of contact system dorsad, above-mentioned coil and yoke partly are positioned at this cavity and form the semi-surrounding structure.After adopting said structure, make this relay both can improve the heat dispersion of coil, make coil can adopt thinner enamelled wire, the increase number of turn to reach the purpose that power consumption is little, suction is big; Simultaneously can make this relay still can keep the characteristics of original big creepage distance again, make the dielectric withstanding voltage between contact and coil still can reach 5000VAC.
But at present, moving contacting plate in such small high-power relay adopts following structure again mostly: moving contacting plate includes contact jaw, neck and has the base portion of leading foot, and the neck of moving contacting plate is by U-shaped connecting portion and the one transition connection mutually of base portion lower edge; And quiet contact chip also is made of the base portion of the head that is wholely set, kink, neck and band leading foot.This finds in application: the moving contacting plate pliability of (1) this structure is not very good, in actual use, need remedy with bigger ampere-turn power usually; On the other hand, the base portion intensity of this moving contacting plate is also not ideal enough, causes moving contacting plate unsettled phenomenon can occur in course of action.(2) neck of moving contacting plate and the transition region edge between the contact jaw are designed to oblique straight flange, behind contact jaw riveted joint contact, the upper deformation of moving contacting plate usually can occur and irregular phenomenon.(3) rigidity of often opening quiet contact chip of this relay is bigger, need could guarantee the contact of moving contacting plate and the contact of often the opening quiet contact chip steady operation of adhesive and relay reliably with bigger the suction-combining force.If above-mentioned defective overcomes with the gap that dwindles between the contact, then can so that directly influence the useful life of relay, finally reduce the reliability and stability of relay work because of the gap reduces to produce arcing or fusion phenomenon between the contact again.(4) base end in corresponding open side has two U-shaped installing holes, when assembling, the skeleton at two suture introducing needle places needs to aim at respectively behind separately the U-shaped installing hole and does insert action, because the volume of relay own is less, thereby such installing hole and inserting action, can cause manufacturability poor, the drawback that assembling is inconvenient.
