Energy-saving structure of relay

Abstract

The invention relates to an energy-saving structure of a relay, includes the following: elastic swing arm, limit structure, driving structure, The control circuit comprises a movable contact piece anda fixed contact piece. The elastic swing arm moves between the two poles of the limit structure under the push of the driving structure, which drives the movable contact piece to move between the fixed contacts piece, and changes and maintains the contact between the movable contact piece and the fixed contact piece at different positions according to the elastic locking position of the movable contact piece, thereby realizing the opening and closing control of the circuit. As that invention does not rely on the continuous work of the control circuit, By using the positioning function of theelastic swing arm and the limit structure, The control circuit operates in a short time when the controlled circuit switches on and off, and realizes the switching and long-time switching control of the controlled circuit. The control circuit has the advantages of short running time, low power consumption, reliable structure, and wide application range in the fields of machinery, electronics, homeappliances control and automation.

Description

technical field [0001] The invention relates to a relay, in particular to an energy-saving structure of the relay. Background technique [0002] In the fields of machinery, electronics, home appliance control and automation, relays, as the most commonly used electronic control devices, play the role of automatic adjustment, safety protection, and conversion circuits. When the traditional relay is opened and closed by the controlled circuit, the control circuit needs to maintain enough electromagnetic force of the electromagnetic coil to maintain the open and closed state of the circuit, so the energy consumption loss of the control circuit is generated, and the heating of the coil is accompanied by the energy saving and control of the relay. , The application caused a lot of inconvenience. Contents of the invention [0003] The object of the present invention is to address the above-mentioned deficiencies in the prior art, and to design a relay energy-saving structure, wh...
