Abstract

The invention discloses a contactor arc chute mounting device, and the device comprises a positioning mechanism and a jacking mechanism; the positioning mechanism comprises a base, a movable pressing member and a static pressing member; the movable pressing member is telescopically arranged on the base, an elastic member abutting against the movable pressing member is arranged between the movable pressing member and the base, the static pressing component is fixedly arranged on the base, the static pressing component is provided with a guide structure capable of driving the arc extinguishing grid piece supporting feet to deform during pressing, and the pressing mechanism comprises a pressing head matched with the arc extinguishing grid piece in an abutting mode and a driving module used for driving the pressing head to move in the direction of the positioning mechanism; and the elastic acting force applied to the movable pressing component by the elastic component is greater than the acting force required to be applied when the arc-extinguishing grid sheets and the arc-extinguishing grid sheet slots are inserted, clamped and matched with each other. According to the invention, the arc extinguishing grid sheet can be simply and rapidly installed and positioned on the arc extinguishing cover.

Description

technical field [0001] The invention relates to a device for installing arc extinguishing grids of a contactor. Background technique [0002] In a broad sense, a contactor refers to an electrical appliance that uses a coil to flow through a current to generate a magnetic field to close the contacts in industrial electricity to control the load. Applied to electric power, power distribution and power consumption occasions. [0003] The Chinese invention patent a contactor contact arc extinguishing structure and arc extinguishing cover (CN207611722U) that the applicant has applied for recently discloses an arc extinguishing cover structure, including a cover, and the cover is provided with three arc extinguishing chambers arranged side by side , both ends of the length direction of the arc extinguishing chamber are equipped with arc extinguishing mechanisms, the arc extinguishing mechanism includes arc extinguishing components, and the arc extinguishing components can adopt t...
