Abstract

Provided is an electromagnetic relay which can sufficiently dissipate heat generated from a coil to secure desired attracting force even when the electromagnetic relay is miniaturized. The electromagnetic relay includes an electromagnet block and a contact switching mechanism. A movable contact piece of the contact switching mechanism includes a contact attaching portion to which a movable contact is attached, and a first fixed portion attached to a first movable iron piece of the electromagnet block. The first fixed portion is in surface contact with the movable iron piece and is substantially equal in width dimension to the movable iron piece.

Description

technical field [0001] The invention relates to an electromagnetic relay. Background technique [0002] Conventionally, as an electromagnetic relay, there is known an electromagnetic relay having a structure in which a fixed terminal is locked and attached to each bobbin of each electromagnetic block in a press-fit manner, and each The two flanges are connected in parallel with each other so that the electromagnetic blocks can be integrally combined (for example, see Japanese Unexamined Patent Publication No. 2000-315448). [0003] However, in such a conventional electromagnetic relay, when miniaturizing the electromagnetic relay, it is necessary to reduce the width dimension of the movable contact piece due to its structural characteristics. This also causes a reduction in the size of the electromagnet. Therefore, in order to secure the same magnitude of attractive force with a reduced-sized electromagnet, it is necessary to increase the amount of current flow to the coil...
