【考案の詳細な説明】 〔産業上の利用分野〕 この考案は電動機の引出し線固定装置に関し、さらに詳
しく言えば、ロータ位置検出素子を有するプリント基板
を備えた電動機の引出し線固定装置に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a lead wire fixing device for an electric motor, and more particularly to a lead wire fixing device for an electric motor provided with a printed circuit board having a rotor position detecting element. is there.
一般に、電動機の固定子巻線には外部リードとしての引
出し線がハンダ付けされ、また、ホール素子等のロータ
位置検出素子からのリード線も引出されている。電動機
を組み立てるに際して、これらの各引出し線は少なくと
も同電動機の自重に耐え得るようにしっかりと固定する
必要があるとされている。そこで、従来では例えば上記
ロータ位置検出素子を有するプリント基板の所定位置の
２箇所に穴を穿設し、その穴間にインシュロックタイを
挿通して、同インシュロックタイにて引出し線を束ねて
上記プリント基板に固定するようにしている。In general, a lead wire as an external lead is soldered to a stator winding of an electric motor, and a lead wire from a rotor position detecting element such as a hall element is also led out. When assembling the electric motor, it is said that each of these lead wires must be firmly fixed so as to withstand at least the weight of the electric motor. Therefore, conventionally, for example, two holes are formed at predetermined positions of a printed circuit board having the rotor position detecting element, and an insulation lock tie is inserted between the holes, and the lead wires are bundled by the insulation lock tie to print the above. It is fixed to the board.
しかしながら、上記従来例によると、穴開け加工やイン
シュロックタイの挿通作業を必要とするため、作業性が
悪い。そればかりか、個人差によって固定具合にバラツ
キがあり、信頼性も充分ではないという欠点があった。However, according to the conventional example described above, workability is poor because it requires drilling and insertion of the insulation lock tie. Not only that, there was a variation in the fixing condition due to individual differences, and the reliability was not sufficient.
そこで、例えば実開昭61−180565号公報においては、絶

被せられる蓋体にリード線保持部に嵌合する切欠凹部を
形成し、同蓋体をステータ用枠体に被せるに伴って、そ
の切欠凹部にてリード線保持部を押さえるようにしてい
る。Therefore, for example, in Japanese Utility Model Laid-Open No. 61-180565, a lead wire holding portion composed of a pair of bendable holding tongues is integrally formed on a stator frame body made of an insulating material, and the holding tongues are mutually connected. By bending the lead wire inward, the lead wire is sandwiched therein, and a notch concave portion that fits into the lead wire holding portion is formed in the lid body that covers the stator frame body. The lead wire holding portion is pressed by the notched concave portion when the lead wire holding portion is covered.
これによれば、インシュロックタイなどの締め具が不要
となり、作業性もある程度は改善されるが、なおもいく
つかの解決すべき問題点が残されている。This eliminates the need for fasteners such as insulation lock ties and improves workability to some extent, but still leaves some problems to be solved.
まず、このリード線保持部はリード線を保持する目的だ
けのもので、そのためにステータ用枠体の成形金型に新
たなる変更を加えなければならない。また、新規に成形
金型を作り直すにしてもリード線保持部の分だけ金型が
複雑になり、コスト負担が増えることになる。First, the lead wire holding portion is only for holding the lead wire, and for this reason, a new change must be made to the molding die of the stator frame. Further, even if a new molding die is remade, the die becomes complicated by the amount of the lead wire holding portion and the cost burden increases.
次に、作業的に見て、リード線を保持するにあたって、
依然として一対の保持舌片を互いに内側に折り曲げる工
程を必要とし、さらには蓋体をステータ用枠体に被せる
にしても、その切欠凹部とリード線保持部との位置合わ
せが必要となり、その分余計なチェック工程を設けなけ
ればならない、などの欠点がある。Next, from a working point of view, when holding the lead wire,
It still requires a step of bending the pair of holding tongues inward with each other, and further, even when the lid body is covered with the stator frame body, the notch concave portion and the lead wire holding portion need to be aligned, which is an extra amount. There are drawbacks such as having to perform a check process.

したことにある。The present invention has been made to solve the above-mentioned conventional problems, and its structural feature is to have an end plate made of an electrically insulating material attached to an end portion of a stator core, and to stand on the end plate. In an electric motor in which a printed circuit board having a rotor position detecting element or the like is held by an engaging claw serving as a wire guide, a U-shaped portion through which a lead wire of the electric motor is inserted is provided at an upper end portion of the engaging claw. A groove having a predetermined depth is formed, a shoulder portion that defines the mounting height of the printed circuit board is provided on the engaging claw, and a notch groove that fits into the engaging claw is formed on the printed circuit board side. The lead wire is fixed between the inner wall of the groove and the printed circuit board as the engaging claw holds the printed circuit board.
上記の構成によると、電動機の引出し線を係合爪の溝内

にてその引出し線を固定することができる。According to the above configuration, the lead wire of the electric motor is inserted into the groove of the engaging claw, and then the lead wire is connected by the extremely simple so-called one-touch operation in which the printed circuit board is engaged with the engaging claw. Can be fixed.
