Relay with anti-inversion function

Abstract

The invention relates to the technical field of relays, and particularly discloses a relay with an anti-inversion function. The relay comprises an insulating shell, a motor arranged in the insulatingshell, a speed reduction unit, a moving terminal and a static terminal. The speed reduction unit comprises an outer shell, an inner shell, a supporting frame and a planet wheel. The outer shell and the inner shell are provided with a first inner gear ring and a second inner gear ring which are meshed with the planet wheel. The shell is provided with an accommodating cavity and an elastic buckle. The inner shell is rotatably contained in the accommodating cavity, and the inner shell is limited in the accommodating cavity through the elastic buckle. A motor drives the planet wheel through a driving wheel to enable the inner shell to rotate, the rotating inner shell drives the movable terminal to move, and the movable terminal can be connected or disconnected with the static terminal throughforward rotation or reverse rotation of the motor. After the motor stops rotating, an elastic force of the movable terminal acts on the inner shell, an acting force of the inner shell is transmitted to the planet wheel, and the outer shell is meshed with the planet wheel and is fixed so that a thrust effect on the planet wheel is achieved, and a situation that the planet wheel rotates reversely, and a state of the terminal is changed is prevented.

Description

technical field [0001] The invention relates to the technical field of relays, and particularly discloses a relay with an anti-reverse function. Background technique [0002] The relay is an automatic switch commonly used in various circuits. During the use of the relay, it is necessary to use the power unit to drive the contact unit to turn on or off. During the use of the relay, the contact unit mostly has a certain reset elasticity. The reset elasticity of the contact unit often leads to the change of the state of the contact unit and the poor use. SUMMARY OF THE INVENTION [0003] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the present invention is to provide a relay with an anti-reverse function. When the motor stops, the elastic force of the moving terminal acts on the inner shell, and the force of the inner shell is transmitted. As for the planetary gear, since the outer casing meshes with the planetary gear and the outer...
