Problems solved by technology

The operation of the transmission part mainly depends on the traction and guidance of the moving iron core in the magnetic circuit system, and then the connection and breaking of the contact part is operated by the transmission of the metal push rod. Due to the high life requirements of the product, the moving iron core in the magnetic circuit system The operating action of the moving bridge and the reliability of the operating action of the moving bridge plate are very high, so the moving iron core may have a large air pressure resistance during operation, resulting in large power consumption, and the rotati

Abstract

The invention relates to the technical field of contactors, in particular to a DC contactor. The DC contactor comprises an insulating shell, a sealing component, an electrical contact component, a mechanical transmission component and an electromagnetic driving component; the insulating shell comprises a shell, an upper cover arranged at the top of the shell, a side cover plate arranged on the side surface of the shell and a shearing protective cover arranged at the top of the upper cover; and a guide positioning column for guiding and positioning the movable bridge plate is arranged in the insulating cover. Through the arrangement of a gasket, an over-travel spring and a limiting clamp spring, the action of the movable bridge plate and the contact pressure of the movable bridge plate andthe static contact are ensured; through the arrangement of the guide positioning column, the reciprocating motion of the movable bridge plate can be matched, the shaft rotation range in the movement of the movable bridge plate is limited, and the contact reliability of the movable bridge plate and the static contact is ensured to be improved.

Description

technical field [0001] The invention relates to the technical field of contactors, in particular to a DC contactor. Background technique [0002] The DC contactor in the prior art is mainly composed of a magnetic circuit part, a transmission part and a contact part, and the inside of the product is filled with nitrogen or a mixed inert gas to extinguish the arc to ensure the product life. The operation of the transmission part mainly depends on the traction and guidance of the moving iron core in the magnetic circuit system, and then the connection and breaking of the contact part is operated by the transmission of the metal push rod. Due to the high life requirements of the product, the moving iron core in the magnetic circuit system The operating action of the moving bridge and the reliability of the operating action of the moving bridge plate are very high, so the moving iron core may have a large air pressure resistance during operation, resulting in large power consumpt...
