Abstract
The utility model relates to a small high power bistable relay, particularly a device which has two-way pulse voltage trigger, and bistable contact latching and releasing. The utility model is used for controlling the high power electric apparatus. A main iron core penetrates through a main framework which is wound with a main coil. The main iron core is fixed on a yoke iron. A movable spring strip connects an armature iron and the yoke iron into a whole to form a main magnetic circuit. The movable contact of the movable spring strip forms a conversion output with a static plug pin. The upper part and the lower part of the static plug pin are fixed with static contacts. An auxiliary iron core penetrates through an auxiliary framework which is wound with an auxiliary coil, and the auxiliary iron core is fixed on the yoke iron to form an auxiliary magnetic circuit. The movable spring strip is also provided with a lock hole. The auxiliary magnetic circuit also comprises a lock strip which is fixed on the main framework. The lock strip is matched with the lock hole of the movable spring strip to form a latching and releasing mechanism. The main framework is perpendicular to the auxiliary framework. The utility model has the advantages of simple structure, compact structure, small volume and power consumption saving.

The utility model relates to a kind of relay; particularly a kind of two-way pulse voltage triggers, the bistable state contact is latched, discharged; be used for the control of high-power electric appliance; as the special purpose relay of IC-card formula pre payment watthour meter overcurrent, overload protection, make the small-sized high-power bistable relay that the long energize diverter switch of no quiet consumption device uses.
The control of existing high-power electric appliance also need add additional mechanism providing additional operations such as latching circuit, and its adapted circuit cost height, volume is big, energy consumption is big.
The purpose of this utility model is to provide a kind of small-sized high-power bistable relay, need not any latching circuit, not power consumption of static state and compact conformation, little, the good reliability of volume.
The utility model is achieved in that the small-sized high-power bistable relay is passed the main framing that is wound with main coil by main iron core, be fixed on the yoke, and movable contact spring is with armature, the yoke formation main magnetic circuit that fuses, moving contact on the movable contact spring be fixed with fixed contact on, down quiet pin constitutes conversion output, pay iron core and pass the skeleton of paying that is wound with pair coil, be fixed on to constitute on the yoke and pay the magnetic circuit composition, and also have lockhole on the movable contact spring, pay magnetic circuit and also comprise the locking plate that is fixed on the main framing, locking plate cooperates with lockhole on the movable contact spring to form and latchs, relieving mechanism, main framing is vertical with pair skeleton.
Fig. 1. structural representation of the present utility model.
Fig. 2. course of work schematic diagram A, B.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
The front end of movable contact spring (5) is by reinforced sheet (10) riveted joint one powerful moving contact (18), an insulating case (21) is fixed at the middle part, there is the straight corner of two circular arcs at the rear portion, be connected with an end of braiding copper strips (9), the end in addition of braiding copper strips (9) is connected with reinforced sheet (10), on the movable contact spring (5) between moving contact (18), insulating case (21) lockhole is arranged.
Yoke (4) cross section is
Shape.
Main iron core (24) passes the bottom that the main framing (1) of walking around main coil (2) is fixed on yoke (4), and movable contact spring (5) is with armature (8), yoke (4) the formation main magnetic circuit that fuses.
Locking plate (12) is again a latch hook formula armature, and its upper end is a right angle latch hook, and middle facial planes is riveted a U-shaped reseting plate (13), and the lower end is fixed on the main framing (1) with little axle (11) is interspersed by axis hole.
Pay iron core (25) and pass and be wound with the skeleton (14) of paying of paying coil (15) and be fixed on the short vertical plane of yoke (4), vertical with main framing (1) direction.And the reseting plate (13) on the locking plate (12) is close to skeleton (14) face of paying, locking plate (12) upper end pass lockhole on the movable contact spring (5) be mated form latch, relieving mechanism, with pay a coil (15), pay iron core (25), yoke (4) constitutes and pays a magnetic circuit.
All riveting on upper and lower quiet pin (17), (16) has powerful upper and lower fixed contact (19), is fixed on the base plate (6), with moving contact (18) the formation conversion output on the movable contact spring (5).
Main framing (1) is vertical with pair skeleton (14).
Assist an end of movable contact spring (22) to be fixed on leading foot (23) upper end, the contact on the other end is corresponding with quiet pin (20), pays coil (15) lead-in wire and is connected with a pair coil pin (7) by wire clamp (3).
Leading foot (23) and quiet pin (20), movable contact spring pin (26) and 4 masters, pair coil pin (7) all are inserted on the base plate (6), with housing (27) it are sealed the all-in-one-piece relay.
During use, be depicted as release condition as Fig. 2 (A), when at this moment main coil (2) being led to a pulse voltage, at this moment main magnetic circuit work adhesive armature (8) is close to main iron core (24) rapidly, while also moves down simultaneously with the movable contact spring (5) that armature (8) is riveted together, moving contact on it (18) just contacts with last fixed contact (19), when armature (8) during fully with main iron core (24) closure, locking plate (12) in the last lockhole of movable contact spring (5) is because of being subjected to the counter-force effect of reseting plate (13), the latch hook of upper end is just in time buckled in the lockhole of movable contact spring (5), movable contact spring (5) is latched.Pulse voltage is outage later, but at this moment movable contact spring (5) will keep latch mode, and sound point (18) also still keeps in touch with following fixed contact (19).
Be depicted as latch mode as Fig. 2 (B), when at this moment paying pulse voltage of coil (15) input, at this moment pay magnetic circuit work, adhesive locking plate (12) hightails lockhole, and movable contact spring (8) returns, and moving contact (18) is contacted with top centre (19).
When movable contact spring (5) moves, touch auxiliary movable contact spring (22), make the contact action on it reach closed and open the status signal output of forming relay by the insulating case on it (21).
The utility model compared with prior art, because of by latching of forming of the mutually perpendicular magnetic circuit of primary and secondary two covers, Relieving mechanism, namely relay itself has the mechanical latching function, so without any need for latching circuit, and quiet No longer power consumption of primary and secondary coil during attitude, therefore energy-conservation, driving power can increase, thereby can be used for large power, electrically The control of device. And compact conformation, simple, volume is little, reliable in action, easy to use.
