Abstract
The utility model relates to a relay without power dissipation which comprises a bistable relay and a control circuit. The bistable relay is composed of a coil L, an iron core K, magnetic conducting boards M1 and M2 and a brass sheet C. The magnetic conducting board M1 is in U shape. The coil L is wound on the magnetic conducting iron cone K and connected with the lower end of the magnetic conducting board M1. The coil L utilizes the magnetic conducting board M1 to lead a magnetic pole generated by the lower end of the iron core K to the upper end of the magnetic conducting board M1. One end of the brass sheet C is positioned between the contacts A1 and A2 and is absorbed with the contact A1 or A2. The other end of the brass sheet C is fixed on the magnetic conducting board M1. In a control circuit, a relay J and a capacitor C are connected in series and then are in bridge connection between an emitter and a collector of a transistor T. The transistor T is connected with a freewheeling diode D, a bias resistor R and a fuse resistor FR in series. The utility model has the characteristics of simple and practical use, low power consumption and broad application range.
Description
Technical field
The utility model relates to the mechanical contact-type direct current relay.
Background technology
Two kinds of forms are arranged in the existing mechanical contact direct current relay, and a kind of is monostable relay, cheap, easy to use, but power consumption is bigger, and the life-span is short.Another kind is a bistable rel-ay, as the Chinese patent notification number is a kind of pulse self-locking bistable electromagnetic relays of 2266196 bulletins, it comprise housing, magnetizing coil, armature, iron core, yoke, moving contact, fixed contact and by the stepping cam, be installed on shift fork and back-moving spring on the armature, be located at the mechanical lock mechanism that slide block on the movable contact spring etc. is formed.Complex structure, it needs pulse-triggered, and price is higher, uses more inconvenient in the small household appliance of direct current supply.
Summary of the invention
It is a kind of simple and practical, low in energy consumption that the purpose of this utility model is to provide, the relay of applied range.
The utility model is realized by following technical scheme: it comprises bistable rel-ay and control circuit two parts.Bistable rel-ay is by coil L iron core K magnetic conductive board M1, M2, copper sheet C forms, magnetic conductive board M1 is a U-shaped, coil L is wrapped on the conducting magnet core K, and coil L is connected with magnetic conductive board M1 lower end, and utilizes magnetic conductive board M1 to guide the magnetic pole that iron core K lower end produces the upper end of magnetic conductive board M1 into, make between the upper end of the coil L other end and magnetic conductive board M1 the magnetic field that generation one changes with coil L electric current.In above-mentioned magnetic field, establish a copper sheet C.With two permanent magnet B1, B2 same sex end face is bonded at respectively on two faces of two magnetic conductive board M2, and together adheres on the copper sheet C.Copper sheet C one end between contact A 1, A2, and with A1 or A2 adhesive, the other end is fixed on the magnetic conductive board M1.In control circuit, relay J be connected across between triode T emitter and the collector electrode triode T serial connection sustained diode and biasing resistor R, and fuse resistance FR after capacitor C is connected in series.
During the utility model work, in coil L, pass to certain directional current, the action of a magnetic field that produces between magnetic conductive board M1 and iron core K is on two same sex faces of permanent magnet B1 and B2, certainly lead to the one side adhesive, one side is repelled, the result produces the effect of recommending to copper sheet, makes one among copper sheet C and contact A 1, the A2 to contact conducting.After coil current disappears, because permanent magnet makes above-mentioned contact still keep attracting state to the adhesive effect of magnetic conductive board.When passing to reverse current, then copper sheet C will with another contact adhesive conducting, and keep conducting, this just forms the relay bistable state.When the control circuit energized, electric current is by capacitor C, and relay J and diode D get back to power cathode, relay gets electric, after electric capacity is full of electricity, and above-mentioned loop no current flows, triode T base potential is lower than emitter current potential, so end, since capacitor C, the leakage current of diode D, the leakage current of triode T is all less, resistance R is very big again, so the total current that consumes is very faint, power consumption is very low.When deenergization, because the energy storage of capacitor C makes diode D end, while triode T saturation conduction, the electric energy reverse flow that is stored in the electric capacity is crossed relay coil, make the magnetic pole of relay conducting magnet core swing to, and, moving contact is recommended to another stable state by the magnetic field force effect, when the capacitor-discharge approach exhaustion, since permanent magnet B1, the effect of B2, and moving contact will keep this stable state.The utlity model has simple and practical, low in energy consumption, the characteristics of applied range.
