Title:
ELECTROMAGNETIC RELAY
Document Type and Number:
WIPO Patent Application WO/2007/114248
Kind Code:
A1
Abstract:
An electromagnetic relay in which the operating characteristics can be regulated
easily while suppressing variation. Based on magnetization/demagnetization
of an electromagnet block (20) formed by winding a coil (21) around an iron core
(30), one end of a frame-like card (80) is latched to a movable iron piece (50) which
rotates while being attracted to or separated from the magnetic pole (31) of the
iron core (30) and a contact mechanism (70) is driven at the other end of the reciprocating
frame-like card (80), thus opening/closing the contacts of the electromagnetic
relay. A pair of protrusions (84, 84) are protruded on the same axis on the inside
at the one end of the frame-like card (80), opposite side edges of the movable iron
piece (50) are clamped by the one end of the frame-like card (80) and the protrusions
(84, 84), and the gap between the protrusions (84, 84) serves as a regulation hole
(85).
