付構造に関する。[Detailed description of the invention] The present invention relates to a winding frame for winding an excitation winding such as an electromagnetic relay, and in particular, in order to increase the driving efficiency of the relay, a yoke that helps form a magnetic circuit is attached to the outside surface. This article relates to a yoke mounting structure for a winding frame.

従来、この種の巻線枠における継鉄取付構造は、第１図
Ａおよび第１図Ｂに示すように、巻線枠１のフランジ側
面に溝（又は穴）ｌａを設け、この溝１ａにコ字状の継
鉄２の舌片部２ａを挿嵌するものである。Conventionally, the yoke mounting structure for this type of winding frame has been to provide a groove (or hole) la on the flange side surface of the winding frame 1, as shown in FIGS. 1A and 1B, and The tongue piece portion 2a of the U-shaped yoke 2 is inserted into it.

しかしながら、このような構造は巻線枠１を成形する金
型において嵌め合せ溝部を形成するための薄板状の突起
が必要となるため、金型構造の複雑化に伴ない高価格化
を招いている。However, such a structure requires a thin plate-like protrusion for forming the fitting groove in the mold for forming the winding frame 1, which leads to an increase in the price due to the complexity of the mold structure. There is.

さらに上述したような取付構造は舌片部２ａとＲｌａと

価格化をも招く。Furthermore, the mounting structure as described above requires strict fitting dimensional accuracy between the tongue portion 2a and Rla, which also leads to an increase in the cost of manufacturing equipment.

また、この種の継鉄付巻線枠においては、継鉄のＬ字状
に曲折された上縁端面に鉄心を含むスイッチ部の磁性部
材の一部が接触して総合的な磁気回路を構成する。In addition, in this type of winding frame with a yoke, a part of the magnetic member of the switch part including the iron core comes into contact with the L-shaped upper edge end surface of the yoke to form a comprehensive magnetic circuit. do.

このとき、この接触は密接なものでないと磁気効率が低
下し電磁継電器の動作特性が不安定となるため、このＬ
字状の曲げ角度のバラツキは小さい程良い。At this time, if this contact is not close, the magnetic efficiency will decrease and the operating characteristics of the electromagnetic relay will become unstable, so this L
The smaller the variation in the bending angle of the character shape, the better.

しかしながら従来の構造においては、直角的げした舌片
部１２ａを巻線枠１の穴１ａに圧入欺合させるため継鉄
の機械的ひずみが大きくなり、また寸法精度が低いもの
においては圧入後の装着姿勢が変化したり、ガタついた
りして磁気効率が低下するという問題点があった。However, in the conventional structure, the mechanical strain of the yoke becomes large because the right-angled tongue portion 12a is press-fitted into the hole 1a of the winding frame 1, and if the yoke has low dimensional accuracy, There has been a problem in that the wearing posture changes or there is wobbling, resulting in a decrease in magnetic efficiency.

本考案の目的は上記の問題を解決し、電磁継電器の良好

を備えたことを特徴とする。The present invention provides a winding frame in which a yoke that forms a magnetic flux circuit generated by the wound windings is attached to at least a part of the outer surface, and a plurality of winding frames each having a slope that becomes deeper as it goes deeper from the outer surface. A notched slanted groove is provided in the flange portion of the winding frame, and the yoke includes a tongue portion whose edge is bent so as to substantially match the slope of the notched slanted groove, and an upper end of which is bent to approximately match the slope of the notched slanted groove. It is characterized by having an upper edge bent into a substantially L-shape so as to come into contact with the upper flange.

次に、本考案の実施例について図面を参照して説明する
。Next, embodiments of the present invention will be described with reference to the drawings.

所定の取付姿勢が確保できる。In other words, since the yoke 12 is elastically locked to the side of the winding frame 1 by the inclination of the tongue piece 12a provided on the yoke 12 and the inclination of the notch inclined groove 11a of the flange, some changes may be made to the machining dimensions. Even if an error occurs, a predetermined mounting posture can be ensured by the fit between the above-described slopes.
