Abstract

The invention discloses an auxiliary contact unit hung on an alternating current contactor. The auxiliary contact unit comprises a shell of the auxiliary contact unit, two upper through holes and twolower through holes are symmetrically formed in the outer wall of the shell bottom of the shell, upper cavities and lower cavities which are respectively matched with the upper through holes and the lower through holes are formed in the inner wall of the shell, an upper buckle is arranged in the upper cavity, a hook at the front end of the upper buckle extends out of the upper through hole and thedirection of the hook is upward; a lower buckle is arranged in the lower cavity, a hook at the front end of the lower buckle extends out of the lower through hole, and the direction of the hook is downward; upper hanging holes opposite to the upper through holes and lower hanging holes opposite to the lower through holes are formed in the side wall, which is connected with the auxiliary contact unit, of the alternating current contactor. According to the auxiliary contact unit in the invention, an upper hanging buckle and a lower hanging buckle which extend out of the shell are arranged on one side of the shell bottom, the auxiliary contact unit is hung on the side wall of the alternating current contactor through the lower hanging buckle and the upper hanging buckle, the auxiliary contact unit can be conveniently disassembled and assembled, quick replacement operation of the auxiliary contact unit can be realized in a narrow area, and time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of low-voltage electrical components, in particular to an auxiliary contact unit hooked on an AC contactor which is convenient for installation and disassembly. Background technique [0002] AC contactor is an electrical appliance used for long-distance and frequent connection and disconnection of AC and DC main circuits and large-capacity control circuits. Its main control object is the motor, and it can also be used to control electric heating equipment, electric lighting, electric welding Electrical loads such as motors and capacitor banks. [0003] The auxiliary contact unit is an accessory of the AC contactor, which is used to switch on or off the control circuit, or to indicate the working state of the contactor. Generally, the auxiliary contact unit is hooked on the top or side of the AC contactor, and its contacts are connected to the armature of the AC contactor or the movement mechanism associated...
