Title:
ELECTROMAGNETIC RELAY
Document Type and Number:
WIPO Patent Application WO/2018/123793
Kind Code:
A1
Abstract:
In the present invention, a base frame (6) includes a main body (61) that fixedly supports a stator (31A), and a bottom plate (62) having a thickness direction in an extension direction (Z direction) orthogonal to a center axis direction (X direction). An intermediate cover (7) includes: a magnet holding part (71) that holds a permanent magnet (4); and a covering plate (72) facing a contact mechanism (3). An outer cover (8) includes: a top plate (80) facing the bottom plate (62) with the contact mechanism (3) therebetween; and a first side plate (81) extending from one end of the top plate (80) while facing the covering plate (72). A first gap (G1) formed between the covering plate (72) and the bottom plate (62) in the extension direction (Z direction), and a second gap (G2) formed between the covering plate (72) and the top plate (80) in the extension direction (Z direction), are arranged in the extension direction (Z direction) so as to be substantially symmetrical about the covering plate (72), and are provided to face the first side plate (81). Due to this configuration, it is possible to achieve favorable cutoff performance, for example.
