ヒンジ係合させるとともに、可動接触片４を有し
た可動絶縁台５を絶縁シート６を間にして前記可
動鉄片３に取付けるようにしてある。 Conventionally, as shown in FIG. 2, in a general electromagnetic relay, a movable iron piece 3 is hingedly engaged with a yoke 2 to which an electromagnet 1 is attached, and a movable insulating stand 5 having a movable contact piece 4 is placed between an insulating sheet 6. The movable iron piece 3 is attached to the movable iron piece 3.
ところで、可動鉄片３と可動接触片４との絶縁

よつて折り曲げ部が元にもどり可動鉄片３のヒン
ジ部に当たり電磁継電器の誤動作の原因になつて
いた。 By the way, the insulating sheet 6 for insulating the movable iron piece 3 and the movable contact piece 4 is attached by bending the tip 6a so as not to come into contact with the hinge part of the movable iron piece 3. For this reason, the bent portion returns to its original state due to changes over time and hits the hinge portion of the movable iron piece 3, causing malfunction of the electromagnetic relay.
この考案は、上記従来の欠点を克服し、経年変
化による動作異常の少ない電磁継電器を提供する
ことを目的とする。 The purpose of this invention is to overcome the above-mentioned conventional drawbacks and provide an electromagnetic relay that is less likely to malfunction due to aging.
以下、この考案の一実施例を図面を参照にして
説明する。 An embodiment of this invention will be described below with reference to the drawings.

A movable insulating stand 16 on which a movable contact piece 15 having a movable contact 14 is insert-molded is attached with an insulating sheet 17 in between. 18 is a fixed contact, 19 is a terminal to which the fixed contact 18 is attached, 20 is a terminal to which the movable contact piece 15 is connected with a lead wire 21, 22 is a coil terminal,
23 is a return spring for the movable iron piece 13.
つぎに、この考案の要旨である絶縁シート１７

前記凹所３０へ係合させてある。なお、可動絶縁
台１６、絶縁シート１７、および可動鉄片１３、
図示しないリベツト等で一体的に固着してある。 Next, the insulating sheet 17 which is the gist of this invention
The fixing will be explained with reference to FIG. Above the movable insulating table 16, that is, on the movable iron hinge engagement side (opposite the contacts 14 and 18), there is a protrusion 16a located on the side of the end 15a of the movable contact piece 15.
The projecting portion 16a is formed with an inclined surface 30a and a recess 30. Then, the tip end 17a of the insulating sheet 17 is bent along the inclined surface 30a, so that the tip end 17a is engaged with the recess 30. In addition, the movable insulating table 16, the insulating sheet 17, and the movable iron piece 13,
They are fixed together with rivets (not shown) or the like.
この構成によると、絶縁シート１７の先端１７
ａは可動絶縁台１６の凹所３０に固定されるので
折り曲げ部が経時変化等で元へもどることがなく
可動鉄片１３のヒンジ部に影響を及ぼすことがな
く。また、従来のように絶縁シート１７の先端を
折り曲げる必要がなく、可動絶縁台１６に形成し
た傾斜面３０ａに沿つて凹所３０にひつかけるの
み固定ができ組立が簡単になる。 According to this configuration, the tip 17 of the insulating sheet 17
Since a is fixed in the recess 30 of the movable insulating table 16, the bent portion will not return to its original position due to changes over time, etc., and will not affect the hinge portion of the movable iron piece 13. Further, there is no need to bend the tip of the insulating sheet 17 as in the conventional case, and it can be fixed by simply pulling it into the recess 30 along the inclined surface 30a formed on the movable insulating table 16, thereby simplifying assembly.

ない電磁継電器を提供することができる。 According to this invention, the ends of the insulating sheet are engaged with the recesses provided in the movable insulating table, thereby preventing the insulating sheet from returning due to aging, and preventing the ends of the insulating sheet from touching other parts. Since adverse effects can be prevented, it is possible to provide an electromagnetic relay with fewer operational abnormalities due to aging.
