MICRO-JITTER ELECTROMAGNETIC RELAY

WIPO Patent Application WO/2015/089902

A1

A micro-jitter electromagnetic relay comprises a static contact whisker spring (5), a moving contact (6), a magnetic core (7), a coil (9), a moving contact sheet support (10), a spring (11), a bracket (12), a moving contact whisker spring (13), and a static contact (14). The moving contact (6) is provided with a moving contact point (1). The static contact (14) is provided with a static contact point (2). The moving contact point (1) is connected onto the moving contact whisker spring (13). The static contact point (2) is connected onto the static contact whisker spring (5). The contact portion of the moving contact point (1) and the static contact point (2) is an inclined surface. When the electromagnetic relay works, the electromagnetic relay can effectively reduce jitters of the contact points. Because inclined contact is used, a self-cleaning effect is generated between the moving contact point and the static contact point. Compared with straight surface contact, a larger contact area is provided, and a contact resistance is small, which helps a greater current to pass through.
