Description

A kind of magnetic latching relay that current-carrying capability is strong
Technical field
The present invention relates to magnetic latching relay manufacturing technology field, especially a kind of magnetic that current-carrying capability is strong keeps relay Device.
Background technique
Magnetic latching relay has been developed in recent years a kind of new type of relay.Its as other electromagnetic relays, Turn on automatically and cutting action are played to circuit.
Existing magnetic latching relay generally includes plastic casing, multiple conductive leading feets, magnetic circuit system, contact system and pushes away Motivation structure.Multiple conductive leading feets, magnetic circuit system, contact system and pushing mechanism are mounted on plastic casing.The magnetic circuit system System generally includes yoke, coil, armature component, and contact system includes dynamic spring, quiet spring, moves and has movable contact on spring, band on quiet spring There is stationary contact, pushing mechanism includes push card, and armature component connects push card, and push card connects dynamic spring part, conductive leading feet It is connected in the intracorporal one end of shell and dynamic spring and quiet spring, when relay coil leads to direct impulse voltage, magnetic circuit system work, rank Iron component drives push card, and push card pushes dynamic spring displacement, makes movable contact and stationary contact point contact, relay is in an ON state; When the coil of relay leads to reverse impulse voltage, magnetic circuit system works again, and armature component drives push card return, and push card pulls Dynamic spring return, movable contact and stationary contact are detached from, and disconnect contact, relay is in dissengaged positions.
In existing magnetic latching relay structure, when being provided with multiple dynamic springs, unavoidably to have conductive leading feet with Push card arranged crosswise.In the case where magnetic latching relay shell dimension is constant, drawn with the conduction of push card arranged crosswise Foot will be reduced in the size of width direction, this will reduce the current-carrying capability of the conductive leading feet.Currently in order to not making conduction Leading foot is reduced in the size of width direction, can only be increased magnetic latching relay shell dimension, be caused the volume of entire relay Increase, occupancy installation site is just larger, is unfavorable for and other electrical matchings.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of magnetic latching relays that current-carrying capability is strong, in shell dimension In the case where constant, it is possible to increase the width dimensions of the conductive leading feet to intersect with push card are to improve magnetic latching relay Current-carrying capability.
In order to achieve the above objectives, the technical scheme is that a kind of magnetic latching relay that current-carrying capability is strong, including shell Body, multiple conductive leading feets, push card and multiple dynamic springs, one end of each dynamic spring and one end of a conductive leading feet are connected, The conductive leading feet is on shell and one end is stretched out outside shell, and push card and multiple dynamic springs are in shell, described to push away Dynamic card includes that base portion and multiple dynamic spring interconnecting pieces, base portion are connected with armature component, and each dynamic spring interconnecting piece and a dynamic spring are another One end is connected, between the base portion and dynamic spring interconnecting piece by push-pull arm be fixedly connected with or the base portion and dynamic spring interconnecting piece between It is fixedly connected with by push-pull arm and adjacent dynamic spring interconnecting piece is fixedly connected with by push-pull arm, after each dynamic spring interconnecting piece is connect with dynamic spring With one and the dynamic equitant cross section of spring symmetrical plane, the cross-section on all dynamic spring interconnecting pieces is in same plane On, using the cross section on the dynamic spring interconnecting piece as horizontal plane, at least there are two push-pull arms relative to wrong above and below the cross section It opens up and sets, by being arranged in a staggered manner for push-pull arm the conductive leading feet offer that push-pull arm intersects is provided bit space is allowed to lead to increase this The size arrangement of electric leading foot width direction is to improve the current-carrying capability of the conductive leading feet.
