The utility model discloses can realize the monopole control of magnetic latching relay, convenient to use, and have simple structure's advantage.
Description
Technical field
The utility model relates to the relay field, particularly a kind of magnetic latching relay that adopts one pole control.
Background technology
Magnetic latching relay is a kind of bistable relay that is output as, and its output state remains unchanged after the coil voltage cancellation, and the advantage of saving the energy is arranged, and is specially adapted to space system and uses.Its advantage is: mechanical property is good, the magnetic efficiency height, and switch speed is fast.
Conventional magnetic latching relay adopts two coils (first excitation coil and back excitation coil) control usually, gives two coil power supplies respectively by the two-lines road simultaneously; And the magnetic latching relay that adopts single coil control need be turned the polarity of coil power supply usually relay is changed back and forth.Therefore above-mentioned two kinds of relays bring many constant for user's use.
The utility model content
The utility model purpose is the deficiency that overcomes in the above-mentioned technology, and a kind of magnetic latching relay that adopts one pole control and need not reset coil polarity is provided.
One pole control magnetic latching relay described in the utility model comprises by common magnetic latching relay and one pole control module to be formed, and the one pole control module links to each other with the contact and the coil of magnetic latching relay coil.
Described one pole control module comprises resistance, diode, controllable silicon, wherein resistance is connected in series, diode cathode is connected between the resistance, negative pole connects relay coil, the controllable silicon anode connects relay coil, the control utmost point connects relay contact, and negative electrode is connected with ground, and resistance, the relay coil other end connect voltage input end.
The utility model behind the employing such scheme can be realized the control of magnetic latching relay single-point, greatly facilitates the use of relay.
Description of drawings:
Fig. 1 the utility model one pole control magnetic latching relay theory diagram;
Fig. 2 the utility model one pole control magnetic latching relay winding diagram.
Among the figure: excitation coil, R1, R2, R3-resistance, V1, V2-diode, K1, K2-controllable silicon behind 1-contact, 2-normally opened contact, 3-elder generation excitation coil, the 4-.
Embodiment
Below in conjunction with the accompanying drawing example the utility model is described further:
Fig. 1 the utility model one pole control magnetic latching relay theory diagram.As shown in Figure 1, one pole control common magnetic latching relay of magnetic latching relay described in the utility model and one pole control module are formed, wherein, what magnetic latching relay adopted is two control coils, it is first excitation coil 3, back excitation coil 4, described one pole control module comprises resistance R 1, R2, R3, diode V1, V2, controllable silicon K1, K2, resistance R 1, R2, the R3 series connection, diode V1, the V2 positive pole is connected resistance R 1, between the R2, negative pole connects first excitation coil 3 respectively, back excitation coil 4, controllable silicon K1, the K2 anode connects first excitation coil 3 respectively, back excitation coil 4, the control utmost point is connecting terminal 1 respectively, 2, negative electrode is connected with ground, contact 1,2 are connected resistance R 2 simultaneously, between the R3, resistance R 1, elder generation's excitation coil 3, back excitation coil 4 other ends connect electrical input.
When input powers up, trigger controllable silicon K1 by resistance R 1, R2 and relay contact 1 and drive first excitation coil 3, when the relay conversion, after the contact switches at 2 from 1, the A point has been an electronegative potential by diode V1 and controllable silicon K1 clamp, so can't trigger controllable silicon K2.When the input outage, when treating that electric current is zero in the relay coil, controllable silicon K1 ends.Owing to be magnetic latching relay, so the relay attitude of will remaining stationary is constant after the coil power down.
In like manner, when input powers up once more, trigger the back excitation coil that controllable silicon K2 drives relay by R1, R2 and relay contact 2, relay produces automatic conversion once more.
Thus, the utility model can be realized the control of magnetic latching relay one pole, user Just, and have an advantage simple in structure.
