Problems solved by technology

[0003] The contactor is generally composed of electromagnetic components, movable contact bridge components, and housing components, wherein: the electromagnetic components include iron cores, coils, coil supports, upper and lower magnetic plates, and the housing components include shells, fixed electrodes, and bases. , the movable contact bridge components include contact bridge, push rod, overtravel reed. The contact bridge and push rod are metal parts. The internal instantaneous working temperature is very high, and the temperature resistance of the built-in insulating parts is poor, which undoubtedly reduces the service life of the insulating parts, thus affecting the use of electrical products

Abstract

The invention discloses an external insulation contactor which comprises an electromagnetic element (2), a movable contact bridge element (3) and a housing element (1), wherein a spring seat (34) for fixing an upper spring (35) is riveted on the contact bridge (31) and the push rod (32) of the movable contact bridge element (3); and an insulator (4) is mounted between the electromagnetic element (2) and the base (13) of the housing element (11). The external insulation contactor adopts integral insulation isolating the whole internal electromagnetic element from an external joint, so that the internal metallization degree of the contactor is higher, the assembling operation is more convenient and quicker, the temperature resistant performance and the work efficiency of the contactor are improved, potential safety hazards are reduced, the service life of the contactor is prolonged, and the product quality is remarkably improved.

Description

technical field [0001] The invention relates to a contactor for commutation or on-off control of electric current. Background technique [0002] A contactor is an electrical product equipped to control the power supply to the line, reversing the current, or controlling on-off. It is widely used in household appliances and industrial products. [0003] The contactor is generally composed of electromagnetic components, movable contact bridge components, and housing components, wherein: the electromagnetic components include iron cores, coils, coil supports, upper and lower magnetic plates, and the housing components include shells, fixed electrodes, and bases. , the movable contact bridge components include contact bridge, push rod, overtravel reed. The contact bridge and push rod are metal parts. The internal instantaneous working temperature is very high, and the temperature resistance of the built-in insulating parts is poor, which undoubtedly reduces the service life of t...
