Abstract

Embodiments of the present disclosure provide a wiring module used in combination with a contactor and a contactor assembly including the wiring module. The junction module comprises at least one set of first conductive parts, each set comprising a fixed part and a movable part, the movable part being adapted to be arranged in a closed position electrically coupled with the fixed part or in an open position electrically decoupled from the fixed part position; and a switching member extending along the longitudinal axis and suitable for disposing the movable part on it, the switching member can be driven by the movable contact of the contactor to reciprocate along the axis, so that the movable part is in the closed position and the off position switch between the open position and at least one of the movable part and the movable contact is in the open position. Embodiments of the present disclosure provide a reliable and low-cost star-sealed wiring module, which is suitable for use in various control circuit systems in cooperation with contactors.

Description

technical field [0001] Embodiments of the present disclosure generally relate to the field of electrical equipment, and more specifically, relate to a wiring module used in combination with a contactor and a contactor assembly. Background technique [0002] At present, permanent magnet synchronous motors (PMSM) are widely used in automatic control systems of various electrical equipment. However, after the permanent magnet synchronous motor stops, its motor rotor will continue to rotate for a period of time due to the effect of inertia. In this case, the permanent magnet synchronous motor will become a power generating device, causing safety hazards. In order to overcome the above problems, the current common solution is to short-circuit the permanent magnet synchronous motor after shutdown. In this way, the motor rotor will be subjected to resistance when it continues to rotate due to the effect of inertia, thereby stopping the rotation. [0003] One solution to realize ...
