Description
Technical field
The present invention relates to a kind of relay, particularly relate to a kind of small size magnetic and keep power relay.
Background technology
Along with improving constantly of environmental requirement, magnetic latching relay has obtained using more and more widely as a kind of energy saving component.Different from simple electromagnetic relay, magnetic latching relay uses permanent magnet, realizes the maintenance of the actuating of relay by the magnetic force of permanent magnet, thereby reduces energy consumption.In more existing magnetic latching relays, although permanent magnet can produce the suction that makes armature remain on the operating position place at the operating position place, make armature to the trend of operating position motion but usually still have at involution position permanent magnet suction, must rely on spring force to make armature remain on the involution position.This is subject to certain impact and very easily makes armature get back to operating position by the involution position so that the performance of relay opposing vibration is generally relatively poor, affects the serviceability of relay.On the other hand, existing this small size magnetic keeps power relay, and the distance of magnetic circuit part and contact portion is less, makes the creepage distance between relay input and the output shorter, causes the fail safe of relay inadequate.In addition, existing this magnetic latching relay, iron core and a yoke wherein are made as one usually, and iron core is cylindrical, and yoke is cuboid, so that whole part shape is comparatively complicated, difficult processing.
