Embodiment Construction

[0016] Such as figure 2 As shown, the present invention discloses a conversion-type functional relay, which includes a bracket 3, an input terminal 1, an output terminal 2, a light-emitting diode D10, a photodiode array D20, a depletion-type MOS tube M1 and an enhanced MOS tube M2. The diode D10 , the photodiode array D20 , the depletion MOS transistor M1 and the enhancement MOS transistor M2 are integrated on the bracket 3 .

[0017] Among them, the input terminal 1 includes a positive input pin 11 and a negative input pin 12; the output terminal 2 includes a common pin 21, a normally closed pin 22 and a normally open pin 23, and the common pin 23 and the normally closed pin 22 are connected to each other. The closing function of the relay is realized when it is connected, and the disconnecting function of the relay is realized when the common pin 21 and the normally open pin 23 are connected.

[0018] The anode of the LED D10 is connected to the positive input pin 11 , and...

Abstract

The invention relates to a conversion type function relay. The conversion type function relay comprises an input end, an output end, a light-emitting diode, a photosensitive diode array, a depletion type MOS tube M1 and an enhanced type MOS tube M2; the input end comprises a positive input pin and a negative input pin; the output end comprises a public pin, a normal-close pin and a normal-open pin; the anode of the light-emitting diode is connected with the positive input pin, and the cathode is connected with the negative input pin; the photosensitive diode array closes to the light-emittingdiode; the anode of the photosensitive diode array is connected with the grid of the depletion type MOS tube M1, and the drain of the depletion type MOS tube M1 is connected with the normal-close pin,and the source is connected with the public pin; the grid of the enhanced type MOS tube M2 is connected with the cathode of the photosensitive diode array, the drain of the enhanced type MOS tube M2is connected with the normal-open pin, and the source is connected with the public pin. In comparison with the way of realizing switching by using the mechanical action, the non-contact switching of the mechanical action is realized in the switching of the relay, the switching frequency is faster, and the service life is longer.

Description

technical field [0001] The invention relates to the technical field of electrical appliances and electronics, in particular to a conversion-type functional relay. Background technique [0002] Change-over relays are an important classification in relays, especially in the signal relay industry. Such as figure 1 As shown, the current conversion relay generally includes an electromagnet 1', an armature 2', a moving contact 3', a normally closed contact 5', and a normally open contact 4'. When the electromagnet 1' is energized, The electromagnet 1' produces an attractive force on the armature 2', making the movable contact 3' contact with the normally open contact 4'; after the power supply of the electromagnet 1' is disconnected, the movable contact 3' contacts the normally closed contact under the action of the spring Contact 5'. The conversion relay adopts mechanical movement to push the movable contact to contact with different conversion contacts, which has the inevitab...
