以下図面によって本発明の実施例を説明する。   Embodiments of the present invention will be described below with reference to the drawings.

本発明においては図１に示すように固定子鉄芯１の外周面の一部にモータの軸方向に互いに離間して延びる２本の溝１２，１２を形成し、この溝１２，１２に合致する突条１３，１３を図２に示すようにコンデンサ４の背面に形成し、上記コンデンサ４の突条１３，１３を上記固定子鉄芯１の溝１２，１２に圧入することによって上記コンデンサ４を上記固定子鉄芯１に着脱自在に固定せしめる。   In the present invention, as shown in FIG. 1, two grooves 12, 12 extending apart from each other in the axial direction of the motor are formed in a part of the outer peripheral surface of the stator core 1, and match the grooves 12, 12. As shown in FIG. 2, the protruding ridges 13 and 13 are formed on the back surface of the capacitor 4, and the protruding portions 13 and 13 of the capacitor 4 are press-fitted into the grooves 12 and 12 of the stator core 1. Is detachably fixed to the stator core 1.

また、上記コンデンサ４の上面にはピン端子状電気的接続端子１５を立設せしめ、上記コンデンサ４を上記固定子鉄芯１に固定した状態でこの端子１５の高さを上記ボビン巻きコイル８のピン端子１０と略同一ならしめる。   A pin terminal-like electrical connection terminal 15 is erected on the upper surface of the capacitor 4, and the height of the terminal 15 is set to the height of the bobbin winding coil 8 in a state where the capacitor 4 is fixed to the stator core 1. It is almost the same as the pin terminal 10.

また、本発明においては図１に示すように電気的接続用の複数のピン端子１４を立設した端子台１６を固定子鉄芯１に固定せしめる。例えば、図３，図４に示すようにこの端子台１６の下面に突出部１６ａを突設し、この突出部１６ａを固定子鉄芯１に形成した孔１６ｂに挿入せしめることによって上記端子台１６を固定子鉄芯１に固定する。   Further, in the present invention, as shown in FIG. 1, a terminal block 16 erected with a plurality of pin terminals 14 for electrical connection is fixed to the stator core 1. For example, as shown in FIGS. 3 and 4, a protruding portion 16 a is provided on the lower surface of the terminal block 16, and the protruding portion 16 a is inserted into a hole 16 b formed in the stator core 1, thereby the terminal block 16. Is fixed to the stator core 1.

また、図５に示すように上記コイル８のピン端子１０と端子台１６のピン端子１４及び上記コンデンサ４の端子１５を挿入せしめる孔１７〜１９と、これらピン端子１０，１４及び１５間を接続するプリント配線２０とを形成したプリント配線基板２１を上記ピン端子１０，１４及び１５が突出する側のモータ側面に被せ、上記孔１７〜１９に夫々上記ピン端子１０，１４及び１５が挿入されるようにし、これによって上記プリント配線基板２１に形成したプリント配線２０が上記コイル８のピン端子１０と上記端子台１６のピン端子１４及び上記コンデンサ４の端子１５間を電気的に接続するようにする。   Further, as shown in FIG. 5, the pin terminals 10 of the coil 8, the pin terminals 14 of the terminal block 16, and the holes 17 to 19 into which the terminals 15 of the capacitor 4 are inserted, and the pin terminals 10, 14 and 15 are connected. A printed wiring board 21 formed with a printed wiring 20 to be covered is placed on the side surface of the motor from which the pin terminals 10, 14 and 15 protrude, and the pin terminals 10, 14 and 15 are inserted into the holes 17 to 19, respectively. Thus, the printed wiring 20 formed on the printed wiring board 21 electrically connects the pin terminal 10 of the coil 8 to the pin terminal 14 of the terminal block 16 and the terminal 15 of the capacitor 4. .

また、本発明においては図６に示すように上記端子台１６上にそのピン端子１４を囲む端子接続孔２２を形成する絶縁部材２３を被せる。   In the present invention, as shown in FIG. 6, an insulating member 23 that forms a terminal connection hole 22 surrounding the pin terminal 14 is placed on the terminal block 16.

Make sure to insulate.

また、図８に示すように絶縁物製エンドブラケット２と上記端子台１６上に金属製エンドブラケット３を被せ、これを上記固定子鉄芯１の反対側に位置する同様の絶縁物製エンドブラケットと金属製エンドブラケットに取付ネジ（図示せず）によって締付固定せしめる。   Further, as shown in FIG. 8, a metal end bracket 3 is placed on the insulator end bracket 2 and the terminal block 16, and the same end bracket made of the same insulator is placed on the opposite side of the stator core 1. And tighten the metal end bracket with a mounting screw (not shown).

本発明のコンデンサモータは上記のような構成であるから取付ネジやタイラップ等を用いることなくコンデンサを極めて簡単容易にモータに一体に固定することができるようになる。   Since the capacitor motor of the present invention is configured as described above, the capacitor can be fixed to the motor integrally and very easily without using mounting screws, tie wraps, or the like.

なお、一般に進相コンデンサは温度に弱いものであり、高温の生ずる場所での固定は好ましくないが、例えばファンモータにおいてはその固定子鉄芯の温度が高くならないため本発明はファンモータに適用するのが特に好ましい。   In general, a phase-advancing capacitor is weak in temperature and is not preferably fixed at a place where a high temperature is generated. However, in a fan motor, for example, the temperature of the stator iron core does not increase, and the present invention is applied to a fan motor. Is particularly preferred.
