The magnetic latching relay of existing band pushing structure: be made up of base portion, intermediary agency, magnetic circuit part and shell.Wherein: base portion is combined by upper electrostatic spring, lower quiet spring combines and move spring combines directly to be inserted on base and be assembled, and intermediary agency installs spring additional by pushing block and forms; Magnetic circuit part is made up of coil, yoke and disk pack, and be fixedly mounted on the location notch of base after coil and the mutual plug-in mounting of yoke, disk pack relies on the rotating shaft at its center to be fixedly mounted on base on axis hole; Intermediary agency is connected by spring and dynamic spring, is connected by the draw-in groove of pushing block lower part Tiebar structure and armature.The disk pack of the magnetic latching relay of this structure when mounted, through hole must be set in disk pack, the corresponding rotating shaft of special configuration makes disk pack be fixed in the lateral surface insertion of base and can around axis of rotation, in addition, in order to make disk pack stability of rotation, usually will around the central axis of disk pack main body, like this, rotating shaft occupies the space of the magnet steel be placed between two blocks of armature, make the height of magnet steel can only be less than the half of disk pack main body, have impact on the size of the magnetic energy product of magnet steel, thus have impact on power switched and the hold facility of magnetic latching relay.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of part and makes and require low, easy to assembly and can improve magnetic and keep the magnetic latching relay of power switched.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of power magnetic force keeping relay, comprise and connect pedestal, pushing mechanism, contact portion and magnetic circuit part, described magnetic circuit part comprises coil, yoke and disk pack, described pushing mechanism is connected with described disk pack with described contact portion simultaneously, described pedestal comprises base, the first divider wall be wholely set, second divider wall and the 3rd divider wall, the second described divider wall and the 3rd described divider wall are oppositely arranged, described contact portion is fixedly mounted on described base, be fixedly mounted on the second described divider wall and the 3rd described divider wall after described coil and the mutual plug-in mounting of described yoke, it is characterized in that described disk pack two ends are respectively provided with rotating shaft, the second described divider wall and the 3rd divider wall all offer draw-in groove, the rotating shaft at described disk pack two ends is connected in corresponding described draw-in groove respectively.
The notch of described draw-in groove is being separately positioned on the side at middle part of the second described divider wall and the 3rd divider wall, the bottom of the lower cell wall of each described draw-in groove all offers location notch, snap in corresponding described location notch again after the rotating shaft at described disk pack two ends snaps in corresponding described draw-in groove respectively, the bore a of the notch of each described location notch is less than the diameter of axle b of described rotating shaft, like this, not only the assembling of disk pack convenient but also firm, improves the efficiency of relay production line simultaneously.
Described disk pack comprises armature, magnet steel and the moulding in order to be connected described armature and described magnet steel, described magnet steel is arranged in the middle of the armature described in two pieces, and three is parallel to each other, described moulding is provided with the dead man connecting described pushing mechanism, rotating shaft described in two is wholely set the two ends at described moulding respectively, like this, and magnetic circuit shift equilibrium, in addition, the manufacturing cost of relay parts is also saved.
Compared with prior art, the utility model has the advantage of: because disk pack two ends of the present utility model are respectively provided with rotating shaft, second divider wall and the 3rd divider wall all offer draw-in groove, the rotating shaft at disk pack two ends is connected in corresponding draw-in groove respectively, first, rotating shaft can not take the space of magnet steel, makes the magnet steel in disk pack can be sufficiently large, improve the magnetic energy product of magnet steel, thus improve power switched and the hold facility of magnetic latching relay; Secondly, disk pack on a production line easy for installation; Finally, the elongated axis hole installing rotating shaft need not be set in disk pack, decrease the difficulty of processing of the part of disk pack.
