Reversing contactor

Abstract

The invention discloses a reversing contactor, which is composed of an electromagnetic construction member, a movable contact bridge construction member (8), an upper contact bridge (10), a lower contact bridge (11), a curve contact bridge (12), a curved bridge stud (13), a reset spring (15) and a shell (9), wherein, the electromagnetic construction member comprises an iron core (1), a coil (2) and a lower magnet conducting plate (3), wherein, a magnet conducting outer ring (4) is arranged at the periphery of the coil (1); the magnet conducting outer ring (4) and the lower magnet conducting plate (3) surround the coil (2) and the iron core (1) in a U-shaped square manner; and an upper magnet conducting plate (5) is arranged above the coil (1). The upper magnet conducting plate, the magnetconducting outer ring and the lower magnet conducting plate wholly encase the coil and the iron core in a full surround type, so as to lead the coil and the iron core to have less leaked magnetism quantity and less magnetic loss when in operation, thereby improving the utilization of the electromagnetism, and promoting the quality of the product.

Description

technical field [0001] The invention relates to a reversing contactor for reversing control of current. Background technique [0002] At present, the reversing contactor is an electrical product, which is composed of electromagnetic components, movable contact bridge components, upper contact bridges, lower contact bridges, curved contact bridges, bent bridge studs, return springs, housings, etc., of which the electromagnetic The components include an iron core, a coil, a magnetically conductive bracket and a lower magnetically conductive plate. The magnetically conductive bracket and the lower magnetically conductive plate enclose the coil and the iron core in a semi-enclosed manner, resulting in magnetic flux leakage, large magnetic loss, and low electromagnetic utilization. Low, thus affecting the use of electrical products. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a reversing contactor wi...
