Problems solved by technology

However, during the opening and closing process of the relay, there will be collisions between the ratchet and the push rod, which will easily cause damage to the relay. At the same time, it cannot be guaranteed that the angle of each rotation of the ratchet must be 90 degrees. The essential

Abstract

The invention relates to a pulse-triggered bistable contactor, which includes a base and a static iron core installed on the upper side of the base. A coil is placed on the static iron core. Moving moving iron core, a static contact is arranged on the upper side of the moving iron core, and a moving contact connected to the moving iron core is arranged above the static contact; a cavity is arranged inside the static iron core, and a cavity is arranged in the cavity of the static iron core The slider is connected with the moving iron core through a push rod. The slider is provided with a self-locking channel forming a closed-loop structure. A lock bar capable of locking its state, the upper end of the lock bar is provided with an upper hook that bends backwards and extends into the self-locking channel. The bistable contactor of the present invention is simple in structure, convenient in installation, debugging and maintenance, more compact in structure, more sensitive in contact action, free of violent collision, and has the characteristics of low power consumption.

Description

technical field [0001] The invention relates to a bistable contactor based on pulse triggering. Background technique [0002] The contactor is a widely used electrical control switching device. The traditional contactor is composed of dynamic and static contacts, coils, iron cores, etc. The closed state of this type of contactor is maintained by electromagnetic force, which not only wastes electric energy, but also makes a lot of noise and the performance is not stable enough. [0003] The permanent magnet bistable contactor has attracted extensive attention due to its advantages of less fault sources, low noise, and low energy consumption in operation. It is mainly composed of coils, armatures, and permanent magnets. However, this kind of contactor has many capacitor coils, which is easy to generate leakage voltage, resulting in unstable opening and closing of the contactor, and weak anti-interference ability. In addition, when the moving contact is broken or pulled in, t...
