しかしながら、このような従来の端子箱付電動機にあっては、端子箱が電動機外枠の側面に設けられていたため、狭いスペースに端子箱付電動機を取り付けるのに邪魔になることがあった。 また、電源ケーブルを端子台に接続する配線作業がしにくいという問題もあった。   However, in such a conventional electric motor with a terminal box, since the terminal box is provided on the side surface of the outer frame of the electric motor, it may be an obstacle to install the electric motor with the terminal box in a narrow space. There is also a problem that the wiring work for connecting the power cable to the terminal block is difficult.

本発明は、上記課題を解決し、端子箱付電動機の組み付け作業性の向上が図れ、かつ端子箱から電動機本体内に粉塵あるいは水が浸入する不具合を防止することができる端子箱付電動機を提供することを目的とする。   The present invention provides an electric motor with a terminal box that solves the above-described problems, can improve the assembly workability of the electric motor with a terminal box, and can prevent a problem that dust or water enters from the terminal box into the electric motor body. The purpose is to do.

First, the board base 40 is assembled to the outer end face 25 a of the outer frame 25 of the motor housing 20. At this time, the front end cylindrical portion 44a of the cylindrical protective wall portion 44 is inserted into the lead-out hole 29, and the substrate base 40 is positioned.
The internal lead wire 28 inserted through the protective wall portion 44 and drawn into the terminal box 3 is inverted and bonded to the printed circuit board 50 by solder or the like. The printed circuit board 50 is assembled together with the terminal block 60 by screwing to the substrate base 40. Next, the board base 40 is screwed into the screw hole 25 c of the outer end surface 25 a of the outer frame 25 of the motor housing 20 through the screw 45. The terminal block 60 is electrically connected to the internal lead wire 28 by being assembled to the printed circuit board 50. Then, the terminal box case 31 is assembled to the outer end surface 25 a of the outer frame 25 of the motor housing 20, and an external line is drawn from the introduction port 35. The external line introduced into the terminal box 3 is guided to the terminal block 60 side along the inclined surface 43 a of the extending portion 43. In this way, an external line is connected to the terminal block 60 to make an electrical connection. Finally, the lid 32 is assembled to the terminal box case 31 to complete the assembly.

以上のように、上記実施の形態によれば、基板台４０の組みつけに際して、円筒状の保護壁部４４の先端筒部４４ａを導出孔２９の内部に挿入して位置決めが図られるので、基板台４０の組みつけを容易に行うことができる。また、外部線は、延出部４３の傾斜面４３ａに沿って、引き入れられ、端子台６０の側に案内されるので、外部線を容易に端子台６０に接続することができる。   As described above, according to the above-described embodiment, when the substrate base 40 is assembled, the distal end cylindrical portion 44a of the cylindrical protective wall portion 44 is inserted into the lead-out hole 29 so that positioning is achieved. The base 40 can be easily assembled. In addition, since the external line is drawn along the inclined surface 43 a of the extending portion 43 and guided to the terminal block 60 side, the external line can be easily connected to the terminal block 60.

なお、本発明は、上記実施の形態のみに限定されるものではなく、例えば、円筒状の保護壁部４４は、内部リード線２８の周囲を保護するものであれば、必ずしも円筒形状である必要はなく、また、延出部４３の傾斜面４３ａは、外部線を案内できるものであれば、角度、あるいは傾斜面４３ａの長さは任意に設定することができる。等、その他本発明の要旨を変更しない範囲内で適宜、変形して実施し得ることは言うまでもない。   The present invention is not limited to the above embodiment. For example, the cylindrical protective wall portion 44 is not necessarily limited to a cylindrical shape as long as it protects the periphery of the internal lead wire 28. Further, as long as the inclined surface 43a of the extending portion 43 can guide the external line, the angle or the length of the inclined surface 43a can be arbitrarily set. Needless to say, the present invention can be appropriately modified without departing from the scope of the present invention.
