Abstract
A novel micro multifunctional magnetic latching relay with manual reset function, comprising a pair of normally opened contacts, a pair of normally closed contacts, and two groups of control coils capable of switching between normally opened and normally closed contacts; the micro multifunctional magnetic latching relay can be electrically reset by a button switch without manually resetting. The micro multifunctional magnetic latching relay has advantages of small volume, high sensitivity, capable of being widely used in automatic control and electric motor protection controller.
Description
One, technical field:
The present invention relates to relay field, particularly magnetic latching relay.
Two, background technology:
Magnetic latching relay is applied in fields such as automatic control, power supply, electric prospection, motor protector widely at present; existing magnetic latching relay is confined to the by turns energising or change the direction of the winding current and make the relay homing of two coils; behind dump; no power supply state is next can't to make the relay homing, makes the range of application of magnetic latching relay be subjected to bigger restriction.If change the structure of magnetic latching relay, increase once manual release link and can use widely in protective circuit, particularly in the passive circuit of motor protection.
Three, summary of the invention:
The objective of the invention is to make a kind of multifunctional magnetic holding relay with reference to existing magnetic latching relay principle.But have little, the simple in structure hand-reset of volume, push-button reset, two-way control, normally opened contact and normally-closed contact exchange etc., present any relay all can't replace, and will be widely used in automatic control and motor protection field.
Technical scheme of the present invention: a kind of multifunctional magnetic holding relay, form by casing, magnet, contact, moving contact skeleton, hand-reset, it is characterized in that magnetic latching relay to be returned to former operating state with hand-reset, also available coil power-on-reset is returned to former operating state with magnetic latching relay.
Above-mentioned said multifunctional magnetic holding relay, it is characterized in that hand-reset is installed between fixed contact 1 and the fixed contact 2, hand-reset masthead portion is equipped with hand-reset spring insertion hand-reset hole and exposes, aim on the moving contact skeleton between moving contact 1 and the moving contact 2, cabinet cover is fixed the hand-reset bar, the hand-reset bar can be cut short arbitrarily according to actual needs than length, puts the hand-reset button then.
Above-mentioned said multifunctional magnetic holding relay, it is characterized in that moving contact skeleton, moving contact 1 and moving contact 2 put into the groove on moving contact skeleton top respectively, moving contact fixedly riveting is fixed this, the moving contact connecting line is connected moving contact 1 respectively with moving contact 2 with the moving contact lead-out wire, the action iron core is installed in moving contact skeleton bottom and the moving contact skeleton constitutes one.
Above-mentioned said multifunctional magnetic holding relay, it is characterized in that supporting iron core and magnet is put into the groove of casing central authorities, supporting iron core exposes at place, support iron core hole, coil 1 and coil 2 are put into the both sides of magnet respectively, expose in the hole of U-iron core insertion coil 1 and coil 2 and at place, U-iron core hole, fixed contact 1 and fixed contact 2 insert respectively in the fixed contact hole and in the bottom and expose as lead-out wire, the moving contact skeleton is put into moving contact skeletal fixation groove, fixed contact 1 and moving contact 1 normally opened contact that partners, fixed contact 2 and moving contact 2 normally-closed contact that partners.
Above-mentioned said multifunctional magnetic holding relay is characterized in that cabinet cover buckles into bottom of shell and sticks in the casing connection button hole, and all lead-out wires expose cabinet cover.
Above-mentioned said multifunctional magnetic holding relay is characterized in that overall structure is identical, large, medium and small, little various kind that size is divided.
