部２６ａを弾性的に押圧している。 In order to stabilize the rotation of the armature 26, a hinge spring 32 presses the bent portion 26a of the armature 26 against the tip 25a of the yoke 25. That is, the hinge spring 32 is
It consists of a mounting base 32a bent in a dogleg shape and a pressing part 32b.The mounting base 32a is inserted into a through hole 26d formed in the second armature portion 26c of the armature 26, and one end thereof is inserted into the yoke 2.
5 by caulking the pin 33, and the pressing portion 32b elastically presses the bent portion 26a of the armature 26.
しかしながら、このような構成を有する従来例
には、ヒンジバネ３２について次のような問題点
がある。 However, the conventional example having such a configuration has the following problems with the hinge spring 32.
即ち、接極子２６の回動に伴つてヒンジバネ３

生じやすく、ヒンジバネ３２の寿命ひいてはヒン
ジ型電磁継電器自体の寿命が短いものとなつてい
る。 That is, as the armature 26 rotates, the hinge spring 3
2 is elastically displaced, but the elastic displacement occurs only at the mounting base 32a, and the armature 26
The pressing portion 32b is in direct contact with the bent portion 26a of
is simply displaced in accordance with the elastic displacement of the mounting base 32a, and does not undergo any elastic displacement itself.
If the pressing force of the bending portion 26a by the pressing portion 32b is weak, the armature 26 may be unexpectedly displaced due to vibration or the like.
There is a risk that the movable contact 28a may unexpectedly come into contact with the fixed contact 27a via the card 30. Therefore, the pressing force of the pressing part 32b on the bent part 26a is made considerably strong, but as mentioned above, the pressing part 32b itself does not undergo elastic displacement as the armature 26 rotates, so the armature With the rotation of 26, the bent portion 26
When a load is applied to the pressing portion 32b from the bending portion 26a, the sliding friction resistance between the bent portion 26a and the pressing portion 32b becomes considerably large. As a result, the pressing portion 32b is likely to wear out, and the life of the hinge spring 32 and the life of the hinge type electromagnetic relay itself are shortened.

るものである。 That is, the hinge type electromagnetic relay of the present invention includes a substantially L-shaped armature connected to a movable contact spring via a card, and a bent portion of this armature rotatably supported from the inside thereof. A hinged electromagnetic relay comprising a fixing member, a hinge spring that presses a bent portion of the armature against the fixing member, and an electromagnet that attracts the armature, wherein the hinge spring is supported on the fixing portion so as to be elastically displaceable. A second leaf spring part that extends continuously and integrally from the free end side of the first leaf spring part so as to be elastically displaceable with respect to the first leaf spring part. The present invention is characterized in that the second plate spring portion is configured to press the bent portion.

第２の板バネ部分も弾性変位する。 In other words, even if the pressing force of the second plate spring portion of the hinge spring against the bent portion of the armature is considerably strong in order to prevent the armature from being accidentally displaced due to vibration, etc., the bending portion of the armature will not be displaced during rotation. When a load is applied to the second leaf spring part, the second leaf spring part itself elastically displaces with respect to the first leaf spring part, and along with this, the first leaf spring part also moves with respect to the fixed part. It is elastically displaced. In other words, not only the first leaf spring portion but also
The second leaf spring portion also undergoes elastic displacement.

自体の寿命を長寿命化することができる。 That is, since not only the first leaf spring part but also the second leaf spring part is elastically displaced as described above, the load that the second leaf spring part receives from the armature bending part is applied to the first leaf spring part. As a result, the sliding friction resistance between the armature bent portion and the second leaf spring portion can be significantly reduced compared to the conventional example. Therefore, it is possible to suppress wear of the second leaf spring portion and extend the life of the hinge spring and thus the life of the hinge type electromagnetic relay itself.

ジ型電磁継電器。[Claims for Utility Model Registration] (1) A substantially L-shaped armature connected to a movable contact spring via a card, and a bent portion of this armature rotatably supported from the inside thereof. a fixed member;
A hinge-type electromagnetic relay comprising a hinge spring that presses a bent portion of the armature against the fixing member, and an electromagnet that attracts the armature, the hinge spring being supported by a first member elastically displaceable on the fixing member. and a second leaf spring part that extends continuously and integrally from the free end side of the first leaf spring part so as to be elastically displaceable with respect to the first leaf spring part. 1. A hinge type electromagnetic relay, characterized in that the bent portion is pressed by a second leaf spring portion. (2) The hinge-type electromagnetic relay according to claim 1, wherein the fixing member is a tip of a yoke coupled to the iron core of the electromagnet. (3) The hinge-type electromagnetic relay according to claim (1), wherein the fixing part is a base that holds the electromagnet.
