Title: Low operating sound electromagnetic relay
Inventor: IKEDA KEIJI
IPC: H01H50/30
Filed: 1992-01-16
Abstract: PURPOSE:To reduce a sound generated at the time of return action by engaging a dome-shaped elastic body having hysteresis between a transfer distance and a load with an armature or a movable contact spring. CONSTITUTION:An armature 4 provided opposite to an end face of an iron core 13 is fixed to the tip of the iron core 13 in free swing through a movable contact spring 5. A dome-shaped elastic body 3 consisting, for instance, of rubber and having hysteresis between a transfer distance and a load is mounted on the tip of this armature 4 for being impressed with a spring load once increased and later again reducing immediately before the movable contact 51 abuts on a fixed contact 52 or 53. Accordingly, a sound caused by a collision of the contact 51 with the contact 52 is reduced while being slowed down by an action of the elastic body 3 immediately before the contact 51 abuts on the contact 52. Further, when the contact 51 abuts on the contact 52, the speed of the armature 4 is further reduced by resiliency of a fixed contact spring 54. The armature 4 is already slowed down before the contact 51 abuts on the contact 52 so as to reduce the sound when the armature 4 collides with the iron core 13.
