Problems solved by technology

Therefore, even if this type of monostable relay does not change state, it still has static power consumption, and its total volume is large, so it is not suitable for occasions with strict requirements on power consumption

Embodiment Construction

[0013] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0014] see figure 1 , is a bistable relay provided by the present invention, which includes an iron core 1 , a first monopole 2 and a second monopole 3 arranged on both sides of the iron core 1 .

[0015] The iron core 1 is strip-shaped, and has a middle section 11 and a first section 12 and a second section 13 arranged at two ends of the middle section 11 . In this embodiment, the iron core 1 is a soft iron core.

[0016] The middle section 11 is in the shape of a rectangular strip with the same width along the length direction. An electromagnetic coil is wound around the periphery of the middle section 11 .

[0017] The widths of the first section 12 and the second section 13 gradually decrease along the direc...

Abstract

The invention relates to a bistable relay, which comprises an iron core, a first monopole and a second monopole located on opposite sides of the iron core, and an electromagnetic coil arranged on the iron core. One monopole is opposite in polarity to the second monopole. The bistable relay only needs to provide a short driving current when changing the state, and does not need continuous coil current to maintain any state, and the power consumption is very low, which is very suitable for occasions with strict requirements on power consumption.

Description

technical field [0001] The invention relates to a relay, in particular to a bistable relay. Background technique [0002] A relay is an electronic control device, usually used in automatic control circuits. The relay switches between two states to make or break the contact points of the contact system, which can be considered as a kind of "automatic switch". Therefore, the relay provides functions such as automatic adjustment, safety protection, and conversion circuit in the automatic control circuit. [0003] There are many kinds of relays. Taking the existing monostable relay as an example, one of the states of the monostable relay does not require additional driving power, and the contact points of the contact system can be directly contacted or disconnected through the metal elastic force, but the other The state needs to energize its electromagnetic coil to generate a continuous electromagnetic force greater than the metal elastic force, so that the contact points of ...
