Abstract

The present disclosure provides a wiring module for use in conjunction with a contactor and a contactor assembly including the wiring module. The wiring module includes at least one set of first conductive members and a switching member, wherein each set of first conductive members includes a fixed portion and a movable portion adapted to be disposed in a closed position electrically coupled withthe fixed portion or an open position electrically decoupled with the fixed portion, the switching member which extends along a longitudinal axis and is suitable for disposing the movable portion thereon is capable of being driven by a moving contact of a contactor to reciprocate along the axis so that the movable portion is switched between the closed position and the open position, and at leastone of the movable portion and the moving contact is located at the open position. The reliable and low-cost star-sealing wiring module is suitable for being matched with a contactor to be applied tovarious control circuit systems.

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 ...
