Embodiment 1

[0020] see Figure 3 to Figure 5 As shown, a double-coil magnetic latching relay for suppressing coil anti-peak voltage according to the present invention includes a housing 81, a spring armature part, a magnetic circuit part and a base part. The armature part of the moving spring includes a moving spring 82, an armature 83, and a moving contact 84. The magnetic circuit part includes a coil, an iron core, a magnetic steel, a pin, and a yoke 85. The base part includes a base 86, a static spring 87, a static contact, stop piece. After the magnetic circuit part is assembled with the moving spring armature part, it is loaded into the base part, and then the shell 81 is assembled to form a relay. The coil includes a set coil 1 and a reset coil 2, and the lead pins include a common pin 3, a set coil pin 4 and a reset coil pin 5, wherein the set coil 1 is connected between the set coil pin 4 and the common pin Between the pins 3, the reset coil 2 is connected between the reset coil...

[0023] see Image 6 As shown, a double-coil magnetic latching relay for suppressing coil anti-peak voltage of the present invention is different from Embodiment 1 in that the setting coil pin 4 and the reset coil of the dual-coil magnetic latching relay A resistor is not connected between the pins 5, but a bidirectional diode 7 for suppressing the reverse peak voltage of the coil is connected, and the bidirectional diode 7 is connected between the pin 4 of the setting coil and the pin 5 of the reset coil.

[0024] A method for suppressing the reverse peak voltage of the coil of a double-coil magnetic latching relay of the present invention is to connect a bidirectional diode 7 between the setting coil pin 4 and the reset coil pin 5 of the double-coil magnetic latching relay. When the setting coil 1 is energized, the bidirectional diode 7 and the reset coil 2 function to suppress the reverse peak voltage of the setting coil 1; when the reset coil 2 is energized, the bidirection...

Abstract

The invention discloses a twin-coil magnetic latching relay used for suppressing coil peak inverse voltages and a suppressing method thereof. A resistor or a bidirectional diode is connected between a set coil pin and a reset coil pin of the twin-coil magnetic latching relay. When a set coil is electrified, the resistor or the bidirectional diode and a reset coil suppress the peak inverse voltages of the set coil. When the reset coil is electrified, the resistor or the bidirectional diode and the set coil suppress the peak inverse voltages of the reset coil. The twin-coil magnetic latching relay which makes the coil peak inverse voltages suppressed makes the number of used components smaller. The relay dimension is reduced. The product cost is lowered. The magnetic latching relay further has the advantages of low power consumption, energy conservation and environmental protection.

Description

technical field [0001] The invention relates to a magnetic latching relay, in particular to a double-coil magnetic latching relay for suppressing coil anti-peak voltage and a suppressing method thereof. Background technique [0002] The magnetic latching relay is a new type of relay developed in recent years, and it is also an automatic switch. The magnetic latching relay, like other electromagnetic relays, can automatically switch on and off the circuit. The difference is that the normally closed or normally open state of the magnetic latching relay is completely dependent on the effect of the permanent magnet, and the switching state of the relay is triggered by a pulse electric signal of a certain width. [0003] In the prior art dual-coil latching relay, in order to suppress the reverse peak voltage of the coil, a resistor or a diode is usually connected to the set coil and the reset coil respectively. This dual-coil magnetic latching relay in the prior art has three c...
