Electromagnetic contactor

Abstract

The electromagnetic contactor according to the present invention comprises: a lower body; a magnetism generating unit installed inside the lower body and magnetized by externally supplied power so as to perform an attraction movement; a crossbar which is coupled to the top of the magnetism generating unit and has a movable contact installed thereon in such a manner to move up and down; a pair of upper bodies which are separately coupled to either side of the top end of the lower body so as to have the movable contact and an auxiliary movable contact positioned therein, and which have end parts, which face each other, correspondingly coupled to either side therein, and which has a fixed contact and an auxiliary fixed contact provided on one side thereof; and a cover which couples the top ends of the pair of upper bodies and exposes the top end of the crossbar and the movable contact to the outside.

Description

technical field [0001] The present invention relates to electronic contactors, and more particularly, to electronic contactors comprising detachable upper bodies each provided with fixed contacts and serving as arc chambers to Productivity is improved, and the electronic contactor is integrally formed with auxiliary contacts without using a separate block, thereby ensuring assembly performance and expansion of auxiliary contacts, thereby improving user convenience. Background technique [0002] Generally, an electronic contactor is an electronic device that builds a magnetic switch (MS) together with a thermal overload relay to prevent overloading and damage to motors, etc. [0003] In this electronic contactor, the electromagnetic part and the contact point part are arranged inside the body, and power is applied to the opposite end of the coil of the electromagnet, so that the power circuit is connected to the load circuit to supply power to the load while closing the conta...

AI Technical Summary

Problems solved by technology

[0005] However, since a typical electronic contactor includes: an integral main body provided with a main contact part and a separate case disposed between the main body and the cover, it is difficult to install the motor inside the body

[0006] Like this, difficulty in modularization of electronic contactors leads to a decrease in productivity, and separate blocks are used to install auxiliary contact points on the upper surface and side surfaces of the main body, thereby deteriorating assembly efficiency and user convenience
