Electromagnetic relay

Abstract

An electromagnetic relay includes a housing; a fixed contact provided within the housing; a movable contact disposed within the housing so as to be contactable to and separable from the fixed contact; a driving unit configured to drive the movable contact, and including a shaft having one end connected to the movable contact and a compression spring for applying an elastic force to the movable contact so as to be in contact with the fixed contact; and an arc protector including an arc shielding portion for shielding an arc, and a compression spring support portion formed to protrude from the arc shielding portion to support the compression spring, the compression spring support portion comprising a shaft accommodating portion for accommodating the shaft therein. Under such configuration, the number of required components can be reduced and generation of a gap can be prevented.

Description

technical field [0001] The present invention relates to an electromagnetic relay, and more particularly, to an electromagnetic relay capable of reducing the number of man-hours in the assembly process. Background technique [0002] As known in the prior art, an electromagnetic relay is a device for opening and closing a main power supply side circuit and a load side circuit. [0003] figure 1 is a sectional view showing an electromagnetic relay according to the prior art, and figure 2 is showing figure 1 An exploded view of the main parts. [0004] Such as figure 1 and figure 2 As shown, a conventional electromagnetic relay includes a contact portion 10 and a drive portion 30 configured to open and close the contact portion 10 . [0005] The contact portion 10 includes a housing 11 , a fixed contact 15 fixedly arranged at the housing 11 , and a movable contact 21 configured to be in contact with or separated from the fixed contact 15 . [0006] The drive section 30 ...

AI Technical Summary

Problems solved by technology

[0019] However, in such a conventional electromagnetic relay, since the buffer rubber 97 is coupled in the protrusion 95 and the compression spring 25 is arranged on the upper portion of the buffer rubber 97, a gap may be formed at the buffer rubber 97, thus the elastic support of the compression spring 25 may be inadequate and inadequate

[0020] In addition, the use of buffer springs 97 results in an increase in components and since the buffer springs 97 are relatively small in size, it is not easy to handle them by hand so that a relatively large number of man-hours are required in the assembly process.
