この考案は、電磁継電器などに使用される電磁
石装置に関する。[Detailed Description of the Invention] This invention relates to an electromagnet device used in an electromagnetic relay or the like.
従来、第１図に示すように、電磁石装置ａは、

ネｆにより可動鉄片ｃを復帰するようになつてい
る。 Conventionally, as shown in FIG. 1, an electromagnet device a is
A movable iron piece c is rotatably supported on a yoke b, and a suction electromagnet e is disposed on one side of the movable iron piece c with respect to a fulcrum d position, while a return spring f is attached to the yoke on one side. Projection piece g of b and movable iron piece c
The electromagnet e is excited to attract the movable iron piece c, while the electromagnet e is demagnetized and the movable iron piece c is returned to its original position by a spring f.

ように可動鉄片ｃと突起片ｇとの間に脱出防止部
材ｉが取付けられている。 The structure of the fulcrum d portion of the movable iron piece c is constructed by forming a U-shaped locking groove in the yoke b, and cutting out fulcrum grooves h on both sides of the movable iron piece c. An escape prevention member i is attached between the movable iron piece c and the protrusion piece g to prevent it from slipping out of the locking groove.
しかし、これでは、バネｆのバネ力は支点ｄを
中心に可動鉄片ｃに作用し、第２図に示すように
バネ力Ｆは可動鉄片ｃに垂直な垂直方向F1と可

の垂直方向力F1は可動鉄片ｃに回動モーメント
として作用し、軸方向力F2は可動鉄片ｃをバネ
ｆ側へ引張する力として作用する。 However, in this case, the spring force of the spring f acts on the movable iron piece c around the fulcrum d, and as shown in FIG . This vertical force F 1 acts on the movable iron piece c as a rotational moment, and the axial force F 2 acts as a force that pulls the movable iron piece c toward the spring f side.
従つて、可動鉄片ｃは、吸引、開放を繰返すう
ち、軸方向力F2のために支点溝ｈの縁部が摩耗
し、バネｆ側へずれることになり、回動不能とな
つて復帰不良を生じるという欠点があつた。 Therefore, as the movable iron piece c repeats suction and release, the edge of the fulcrum groove h wears out due to the axial force F2 , and it shifts toward the spring f, becoming unable to rotate and failing to return. It had the disadvantage of causing

低下するという問題が生じていた。 Therefore, in the above relay j, the movable iron piece c
In addition to the failure to return the movable iron piece c, the position of the movable iron piece c fluctuates, resulting in a drawback that a stable holding operation cannot be performed. Moreover, the play dimension at the holding position provided to cope with the fluctuation of the movable iron piece c changes, and the amount of follow-up of the movable iron piece m that drives the contact l decreases, and the contact force of the contact l and the amount of follow-up. A problem has arisen in which the value decreases.
この考案は、上記従来技術の欠点に鑑みてなさ

動作特性の経年変化の少ない電磁石装置を提供す
ることを目的とする。 This invention was made in view of the above-mentioned drawbacks of the prior art, and aims to provide an electromagnet device that prevents wear of the movable iron piece and the yoke, and whose operating characteristics are less likely to change over time.
以下、図面に示す実施例に基づいてこの考案を
詳細に説明する。 This invention will be described in detail below based on embodiments shown in the drawings.
第４図及至第６図に示すように、１は電磁継電
器などに使用される電磁石装置であつて、可動鉄
片２、吸引用電磁石３及び復帰用バネ４を備えて
いる。 As shown in FIGS. 4 to 6, reference numeral 1 denotes an electromagnet device used in electromagnetic relays, etc., and includes a movable iron piece 2, a suction electromagnet 3, and a return spring 4.
５は電磁石装置１のヨークであつて、床板部５

起されて突出形成されている。 5 is a yoke of the electromagnet device 1, and the floor plate portion 5
A and the side plate portion 5b form a substantially L-shape. A U-shaped locking groove 5c for the movable iron piece 2 is formed in the center of the upper part of the side plate part 5b, and a rectangular projection piece 5d is cut outward and protrudes from the center of the lower part. ing.
前記可動鉄片２は、１枚の板状体であつて、後
部の両側端部にｕ字状に切欠かれた支点溝２ａが
形成されており、両支点溝２ａ間のネツク部２ｂ
が前記係止溝５ｃに挿入されて側板部５ｂと略直
交状態で組合わされる。そして可動鉄片２はこの
ネツク部２ｂと側板部５ｂとの交点を支点ｘにし
て回動する。さらに可動鉄片２の後端中央部には
矩形状の突出部２ｃが後方に延設されている。 The movable iron piece 2 is a single plate-like body, and has U-shaped fulcrum grooves 2a formed at both ends of the rear part, and a neck portion 2b between both fulcrum grooves 2a.
is inserted into the locking groove 5c and combined with the side plate portion 5b in a substantially orthogonal state. The movable iron piece 2 rotates using the intersection of the neck portion 2b and the side plate portion 5b as a fulcrum x. Furthermore, a rectangular protrusion 2c extends rearward at the center of the rear end of the movable iron piece 2.
前記電磁石３は、励磁コイル３ａと鉄心３ｂと
より成り、床板部５ａに取付けられている。つま

設けられ、励磁コイル３ａを励磁して可動鉄片２
を鉄心３ｂに吸引吸着させる。 The electromagnet 3 includes an excitation coil 3a and an iron core 3b, and is attached to the floor plate portion 5a. In other words, the electromagnet 3 is provided in front of the fulcrum x position of the movable iron piece 2, and excites the excitation coil 3a to
is attracted to the iron core 3b.
前記バネ４は引張コイルバネであつて、可動鉄

に可動鉄片２に回動モーメントとして作用し、可
動鉄片２を復帰させる。一方、軸方向力は可動鉄
片２を後方（バネ４側）に付勢している。 The spring 4 is a tension coil spring, and is tensioned between the protrusion 2c of the movable iron piece 2 and the protrusion piece 5d of the yoke 5, and this spring force is applied to the movable iron piece 2 by a vertical force perpendicular to the movable iron piece 2 parallel axial force. Then, this vertical force acts on the movable iron piece 2 as a rotational moment about the fulcrum x, causing the movable iron piece 2 to return to its original position. On the other hand, the axial force urges the movable iron piece 2 backward (toward the spring 4 side).

押圧している。 Further, a member 6 (elastic member) for preventing the movable iron piece 2 from escaping is installed between the side plate portion 5b and the movable iron piece 2 and engages with both. This escape prevention member 6
This prevents the movable iron piece 2 from slipping out above the locking groove 5c. Two through holes 6b and 6c are formed in the vertically long main body 6a, and an engaging piece 6d is diagonally formed on both sides of the upper end. Extended towards the front,
It is made of an elastic material such as a leaf spring material. This escape prevention member 6 has a protruding portion 2c and a protruding piece 5d passing through the through holes 6b, 6c, and is provided between the side plate portion 5b and the spring 4, and the engaging piece 6d contacts the front side edge of the locking groove 5c. However, the main body portion 6a contacts the rear end surface of the movable iron piece 2 and presses the movable iron piece 2 forward (toward the electromagnet 3 side).
従つて、バネ４を取外した状態において、脱出
防止部材６を取付けると、つまり、貫通孔６ｂ，
６ｃに突出部２ｃ及び突起片５ｄを挿入し、係合
片６ｄを係止溝５ｃ縁部の側板部に係合すると、
脱出防止部材６はその弾性力により下端がはね上
がつた状態となる。 Therefore, when the escape prevention member 6 is attached with the spring 4 removed, that is, the through hole 6b,
When the protruding part 2c and the protruding piece 5d are inserted into the locking groove 5c and the engaging piece 6d is engaged with the side plate part of the edge of the locking groove 5c,
The escape prevention member 6 is in a state in which its lower end springs up due to its elastic force.
続つて、バネ４を突出部２ｃと突起片５ｄとの
間に張設すると、バネ力のうち垂直方向力は可動
鉄片２に復帰力として作用する一方、軸方向力は
脱出防止部材６の弾性力と相殺されることにな
る。 Next, when the spring 4 is stretched between the protruding portion 2c and the protruding piece 5d, the vertical force of the spring force acts on the movable iron piece 2 as a restoring force, while the axial force is caused by the elasticity of the escape prevention member 6. It will be canceled out by force.
即ち、この弾性力は可動鉄片２を軸方向に前方
へ押圧し、バネ力の軸方向力は後方へ押圧し、こ
の両者によつて、可動鉄片２の位置決めが行なわ
れる。 That is, this elastic force presses the movable iron piece 2 forward in the axial direction, and the axial force of the spring force presses it backward, and the movable iron piece 2 is positioned by these two.
尚、この実施例においては、脱出防止部材６を
利用して、係合片６ｄにより可動鉄片２を押圧す
るようにしたが、脱出防止部材６とは別個に弾性
部材を形成して、可動鉄片２を押圧するようにし
てもよい。 In this embodiment, the escape prevention member 6 is used to press the movable iron piece 2 with the engaging piece 6d, but an elastic member is formed separately from the escape prevention member 6, and the movable iron piece 2 is pressed by the engagement piece 6d. 2 may be pressed.

ることができる。 According to this invention, in a hinge-type electromagnet device, a protruding piece provided on a yoke, a movable iron piece provided with a fulcrum groove that engages with the protruding piece, and an inner wall of the fulcrum groove are pressed against the protruding piece. The elastic body cancels out the force of the return spring pulling the movable iron piece toward the return spring side, preventing wear at the hinge points of the movable iron piece and the yoke, thereby preventing variations in the operating stroke of the movable iron piece. Therefore, it is possible to provide an electromagnetic device whose operating characteristics hardly change due to aging.
