Abstract
The utility model discloses a relay switch conversion rate's improvement circuit, this circuit include relay coil, triode, resistance, stabilivolt, the projecting pole of triode links to each other with resistance, and the collecting electrode links to each other with relay coil, and the one end of stabilivolt links to each other with the base of triode, and the other end links to each other with the collecting electrode of triode. Because adopt above -mentioned structure, the relay switch conversion rate after the improvement is fast, easy operation, job stabilization.
Description
Technical field
The utility model relates to a kind of relay switch, particularly relates to a kind of improvement circuit of relay switch conversion speed.
Background technology
In conventional relay switch (circuit diagram as shown in Figure 1) control circuit, the effect of diode is the back-emf breakdown transistors preventing relay coil from producing when electric current disconnects, but negative peak pulse voltage controls at about 0.7V by diode, electric current in coil can not disappear very soon, release time can be caused long, and produce jitter phenomenon, in some cases, this phenomenon is extremely harmful to the electric equipment controlled, and must try every possible means to eliminate.We improve original relay switch for this reason, to meet various need of work.
Summary of the invention
The purpose of this utility model is to provide the relay switch that a kind of working stability, conversion speed are fast, cheap, can meet various need of work.
The purpose of this utility model is achieved through the following technical solutions: this circuit comprises relay coil, triode, resistance, voltage-stabiliser tube, the emitter of described triode is connected with resistance, collector electrode is connected with relay coil, one end of voltage-stabiliser tube is connected with the base stage of triode, and the other end is connected with the collector electrode of triode.
Because the energy of inductance release is absorbed by voltage-stabiliser tube and triode, as long as circuit element parameter is selected suitably, just can obtain the velocity of discharge faster.When control signal becomes low level from high level, triode will end, and relay coil produces reverse potential makes voltage-stabiliser tube puncture and provide bias current to triode, so the conducting simultaneously of voltage-stabiliser tube and triode and the energy that absorbs in relay coil.
The beneficial effects of the utility model are: the relay switch conversion speed after improvement is fast, simple to operate, working stability.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of prior art
Fig. 2 is circuit diagram of the present utility model
In figure: 1, relay coil 2, triode 3, resistance 4, voltage-stabiliser tube
Embodiment
As shown in Figure 2, the emitter of triode 2 is connected with resistance 3, and collector electrode is connected with relay coil 1, and one end of voltage-stabiliser tube 4 is connected with the base stage of triode 2, and the other end is connected with the collector electrode of triode 2.Because the energy of inductance release is absorbed by voltage-stabiliser tube 4 and triode 2, as long as circuit element parameter is selected suitably, just can obtain the velocity of discharge faster.When control signal becomes low level from high level, triode 2 will end, and relay coil 1 produces reverse potential and voltage-stabiliser tube 4 punctured and provides bias current to triode 2, so the conducting simultaneously of voltage-stabiliser tube 4 and triode 2 and the energy that absorbs in relay coil 1.
