ELECTROMAGNETIC RELAY
First Claim
1. An electromagnetic relay comprising:
- an electromagnet block comprising a rod-shaped iron core;
a coil wound around an outer peripheral side of the rod-shaped iron core, and a spool interposed between the coil and the rod-shaped iron core;
a yoke having one end section anchored to one end section of the iron core, and other end section extending to a section at a side of a magnet pole section at other end of the iron core, the electromagnet block being arranged on a base so that the magnet pole section of the iron core has a gap on a base side;
a hinge spring anchored to the yoke;
a moving iron configured to be pivotably supported by an elastic support of the hinge spring with the other end of the yoke whereinthe electromagnet block is adapted to be magnetized, such that a section to be drawn in the moving iron, is drawn to the magnet pole section of the iron core and pivoted to drive a contact switching unit;
the hinge spring includes an elastic contacting portion extending toward an opposite side to the elastic support from a position anchored to the yoke, andthe moving iron is integrated, at an opposite side to the section to be drawn with respect to the moving iron, with a card member that comes in contact with the elastic contacting portion before coming in contact with the yoke.

Abstract
An electromagnetic relay including an electromagnet block having a rod-shaped iron core, a coil wound around the rod-shaped iron core, and a spool interposed between the coil and iron core. A yoke having one end section extends to a section at a side of a magnet pole section of the iron core. An end section of the yoke is arranged so that the magnet pole section has a gap on a base side. A moving iron is pivotably supported by an elastic support of a hinge spring. The electromagnet block is magnetized wherein a section drawn in the moving iron is drawn to the magnet pole section and pivoted to drive a contact switching unit. The hinge spring includes an elastic contacting portion extending toward an opposite side to the elastic support. The moving iron is integrated with a card member that comes in contact with the elastic contacting portion.
