Problems solved by technology

In addition, the movable iron core portion 56 is rotated by the magnetic attraction force and the repulsive force, so the rotation angle thereof is restricted and cannot be increased.
[0015] Therefore, in the existing electromagnet device, even if the driving force can be obtained, the linear driving distance relative to the movable contact cannot be increased, and there is a problem that the separation distance of the opening and closing contacts of the electromagnetic relay cannot be increased.

Abstract

The invention provides an electromagnet device capable of increasing the driving force and the linear driving distance and an electromagnetic relay capable of increasing the distance between the switch contact points. The movable iron core of a movable iron core part is formed by the u-shaped iron core of a built-in permanent magnet and the movable iron core part is driven by an electromagnet. The yokes of the movable iron core and the electromagnet are inserted into each other to be assembled, so that one of the core pins parallel to the movable iron core is inserted between the front ends of two parallel yokes of the electromagnet. Meanwhile, the front end of one of the yokes is inserted between the two parallel core pins of the movable iron core. In addition, the lower end of the movable iron core part is rotatably supported.

Description

technical field [0001] The present invention relates to an electromagnet device and an electromagnetic relay using the same. Background technique [0002] In the electromagnetic relay driven by the electromagnet device, the movable iron core part that can be rotatably supported is generally rotated by the magnetic attraction force of the electromagnet and the elastic force of the return spring, and the contact mechanism is directly or indirectly driven by the rotating force, and the contact mechanism can be driven by the rotating force. The opening and closing contacts composed of moving contacts and fixed contacts perform opening and closing. [0003] In particular, in high-standard electromagnetic relays called safety relays, in order to reduce opening and closing failures caused by welding of the switching contacts, even if the switching contacts are welded, they can be peeled off and opened and closed. It is driven by an electromagnet device with a large driving force. ...
