The yoke 1 and the pole piece 2 may be brought into closer contact with each other by the elastic force of the elastic band 12, and as shown in FIG. The portion where the end face of the letter-shaped magnetic pole piece 2 comes into contact may be fixed by welding, fastening, or the like.
上記構造からなる電磁石によれば次のような多
大な効果を奏する。 The electromagnet having the above structure has the following great effects.
(1) 継鉄と磁極片との当接部分がコイルの巻線部
分のスペースを狭くしない箇所にあるので、電
線が多く巻くことが出来、小形にしてしかも感
度のよい電磁石が得られる。(1) Since the contact area between the yoke and the magnetic pole piece is located at a location that does not narrow the space for the winding part of the coil, a large number of wires can be wound, and a compact electromagnet with good sensitivity can be obtained.
(2) コイルボビンの胴部内に磁極片、継鉄、接極
子等の部品を収納せしめ得るので電磁石を極め
て小さく構成し得、もつて電磁継電器自体を小
形にでき得る。(2) Since parts such as the magnetic pole piece, yoke, and armature can be housed within the body of the coil bobbin, the electromagnet can be made extremely small, and the electromagnetic relay itself can be made compact.
(3) 磁極片及び継鉄をコイルボビンにもうけた案
内溝に圧入するだけで固着することができるの
でこの取付け部品を不要ならしめ、かつ組み込
みが容易であるので作業性がよく経済性に富
む。(3) Since the magnetic pole pieces and yoke can be fixed simply by press-fitting them into the guide groove provided in the coil bobbin, these mounting parts are not required, and the installation is easy, so the workability is good and economical.
(4) Ｌ字形の磁極片は曲げ加工において寸法精度

の精度が多少ばらついても、継鉄の遊端部と磁
極片の端面とが当接した時、磁極片の端面が組
立の基準となつているので両者の寸法精度が極
めて安定する。(4) Since the L-shaped magnetic pole piece can be bent with extremely high dimensional accuracy, even if the bending angle accuracy of the L-shaped yoke varies slightly, the free end of the yoke and the end face of the magnetic pole piece can be in contact. Since the end face of the magnetic pole piece serves as the reference for assembly, the dimensional accuracy of both is extremely stable.
(5) 磁極片および継鉄をコイルボビンに設けた案
内溝に圧入するだけで、接極子が接触するヒン
ジ面および磁極面の平担性が出せるので寸法精
度の良い電磁石が得られ、結果として電磁継電
器の小形化に寄与する。(5) By simply press-fitting the magnetic pole piece and yoke into the guide groove provided on the coil bobbin, the hinge surface and magnetic pole surface that the armature contacts can be flattened, resulting in an electromagnet with good dimensional accuracy. Contributes to downsizing of relays.
