[0004] However, thinning is required for the above-mentioned type of electromagnetic relay, and the electromagnet also needs to be formed thinly.
[0005] However, when the electromagnet is formed thinly, the number of turns of the coil is limited, and since the voltage is applied at the same voltage value, the attractive force is low, and there is a problem that the desired operating characteristics cannot be obtained.

[0120] In the above-described embodiment, the protruding portion 39 is formed on the card 21 , but it may be formed on the movable iron piece 20 . The protruding portion 39 may be formed on the movable iron piece 20 as follows. Pressing or the like may be used, or a resin material, metal material, or the like may be attached by bonding, crimping, or the like. The protruding portion 39 may be formed on both the card 21 and the movable iron piece 20 such that the protruding portions abut against each other.

[0121] In addition, it is also possible to form Figure 13 and Figure 14 Such a surface contact portion 50 is used instead of the above-mentioned protruding portion 39 .

[0122] In FIG. 13 , the surface contact portion 50 has an inclined surface formed on the back surface of the card 21 . According to this structure, during the rotation process of the movable iron piece 20 with the excitation of the electromagnet 17, specifically, when the contact is switched, the front...

Abstract

An electromagnetic relay capable of having desired operating characteristics by a simple and inexpensive structure despite the fact that the thickness thereof is small. A movable iron piece (20) is rotated by magnetizing or demagnetizing an electromagnet to elastically deform a movable contact piece (43) through a card (21) to open and close a movable contact (46) from and to the fixed contact ofa fixed contact piece. The movable iron piece (20) comprises a card pressing part (36) capable of pressing the card (21). The card (21) comprises a contact piece pressing part (37) capable of pressing the movable contact piece (43) by rotating around the pivot. At least either of the movable iron piece (20) and the card (21) comprises a pressing position changing part which when the movable iron piece (20) is rotated, makes the card pressing part (36) perform the transmission of a force from the movable iron piece (20) to the card (21) after the transmission is performed at a position apart from the pressing position where the pivot is pressed by the card pressing part (36) of the movable iron piece (20).

Description

technical field [0001] The present invention relates to an electromagnetic relay capable of obtaining desired operating characteristics even if it is thin. Background technique [0002] At present, as an electromagnetic relay, there are, for example: using the excitation and demagnetization of the electromagnet to rotate the movable iron piece, elastically deform the movable contact piece through the card, and open and close the fixed contact between the movable contact and the fixed contact piece oppositely arranged ( For example, refer to Patent Document 1). [0003] Patent Document 1: (Japanese) Unexamined Patent Publication No. 2004-327236 [0004] However, the electromagnetic relay of the above-mentioned type is required to be thinner, and the electromagnet also needs to be formed thinner. [0005] However, when the electromagnet is formed thin, the number of turns of the coil is limited, and since the voltage is applied at the same voltage value, the attractive force...
