Abstract

The invention discloses an electromagnetic relay, and the relay comprises a shell which has a partition plate, wherein the partition plate divides the internal space of the shell into an upper accommodating chamber and a lower accommodating chamber; a top cover which is arranged on the top opening of the shell so as to seal the top opening; and a contact system which is arranged in the upper accommodating chamber of the shell and comprises a main contact and an auxiliary contact. A main static contact in the main contact is fixed to the top cover, and the auxiliary contact is fixed to the partition plate, so that the distance between the main contact and the auxiliary contact in the height direction and the creepage distance between the main contact and the auxiliary contact are increased. Therefore, the electrical insulation performance and the safety performance of the electromagnetic relay can be improved.

Description

technical field [0001] The invention relates to an electromagnetic relay. Background technique [0002] In the prior art, an electromagnetic relay generally includes a housing, a contact system and an electromagnetic system. A partition plate (or called a fixed base) is formed inside the housing, and the partition board divides the inner space of the housing into upper and lower accommodation chambers. The contact system is installed in the upper accommodation chamber of the housing. The electromagnetic system is installed in the lower accommodation chamber of the housing. An electromagnetic system is used to drive the active contact movement of the contact system. The electromagnetic system mainly includes a coil bobbin, a magnetic plate, a yoke, a coil and an iron core. [0003] In the prior art, the electromagnetic relay also includes an auxiliary contact for monitoring the electrical connection state of the active contact, and the auxiliary contact is usually install...
