にさらされると電位差腐食により電位の低い鉄（継鉄の
加締部）が腐食し、アース端子の固定がゆるんだりまた
導通不良を発生するという問題があった。The ground terminal is made of brass, etc., and the yoke is made of iron. Because these are assembled in contact with each other, if exposed to a corrosive environment such as salt water, potential difference corrosion will occur, causing corrosion of the iron with a low potential (the caulked part of the yoke). ) corroded, causing problems such as the ground terminal becoming loose and causing poor continuity.

た。In addition, it requires the use of a ground terminal and the man-hours of caulking and fixing it to the yoke. Furthermore, in order to pull out the ground side end, a grommet is required to prevent resin from leaking from the yoke's pull-out hole. This was a factor that increased manufacturing costs.
本発明の目的は、腐食環境にさらされても信頼性があり
、かつ安価なボディアースの接続構造を提供することに
ある。An object of the present invention is to provide a body ground connection structure that is reliable and inexpensive even when exposed to a corrosive environment.

不要となり、原価低減も図ることができる。The body entry part is not exposed to the outside, and reliability will not deteriorate even if exposed to a corrosive environment. Further, in order to perform body grounding, special parts (earth terminals, grommets) and special processes (crimping work, etc.), which were required by conventional techniques, are no longer necessary, and costs can be reduced.

Here, the recess 15b is provided to accommodate the ground side end 11a of the excitation coil 11, and the step C in this portion is designed to be slightly smaller than the diameter of the coil. Further, the bow hole 15c provided in the side plate portion 15a is a through hole for drawing out the lead wire 12 attached to the excitation coil 11,
The positioning hole 15d is a blind hole into which the convex portion 13e of the bobbin 13 is fitted and the two are positioned. Further, inside the thick side plate part 15a, a thin mounting part 15e for attaching to the rotating machine 1 is integrally formed, and a stepped part 15f formed by the side plate part 15a and the mounting part 15e will be described later. It is finished by cutting to a fitting diameter φD1 into which the yoke auxiliary member 16 is press-fitted.

a, and a stepped portion 16b at the other end that serves as a stopper for the bobbin 13.
It has a roughly cylindrical shape and is made by cutting and finishing a mild steel pipe.
以上述べた各部品は次の如くの工程で組立てられる。The parts described above are assembled in the following steps.
（１）ボビン１３に巻いた励磁コイル１１を、まず第８
図に示すように、継鉄補助部材１６の圧入部側よりそう
人する。(1) First, the excitation coil 11 wound around the bobbin 13 is
As shown in the figure, it is inserted from the press-fitting part side of the yoke auxiliary member 16.
（２）上記工程で外周に励磁コイル１１を取付けた継鉄
補助部材１６の圧入部１６ａを、第９図のとおり、継鉄
主部材１５の段付部１５ｆに圧入し、補助部材１６の０

The surface comes into contact with the zero surface of the main member 15, and the integration of the two is completed.
なお、圧入作業時、リード線１２の外部への引出し作業
も同時に行われ、継鉄主部材１５の引出穴１５ｃよりグ
ロメット１８を介して主部材１５の背面へ取出される。Note that during the press-fitting operation, the lead wire 12 is pulled out to the outside at the same time, and is taken out from the pull-out hole 15c of the yoke main member 15 to the back side of the main member 15 via the grommet 18.
（３）主部材１５に設けた凹部１５ｂの段差Ｃがコイル
の外径すよりも小さく設計されているため、上記の如く

して電気的に接続され５確実にボディアースされる。(3) Since the step C of the recess 15b provided in the main member 15 is designed to be smaller than the outer diameter of the coil, the excitation coil The ground side end portion 11a of 11 is crimped and clamped between the zero surface of the recess 15b and the zero surface of the auxiliary member 16. As a result, the ground side end portion 11a makes metal contact with the yoke 14 and is electrically connected to the yoke 14, thereby ensuring that the body is grounded.
（４）この様にして、励磁コイル１１の継鉄側への組込
みが完了した後、継鉄１４の開口部側から注形樹脂１９
を注入し、乾燥固着して、励磁コイル１１を継鉄１４に
絶縁固着して本発明の励磁装置１０が完成する。(4) After the excitation coil 11 has been assembled to the yoke side in this way, the molded resin 19 is inserted from the opening side of the yoke 14.
is injected, dried and fixed, and the excitation coil 11 is insulated and fixed to the yoke 14, thereby completing the excitation device 10 of the present invention.
本発明は１以上説明したように構成されるので、以下の
効果を得ることができる。Since the present invention is configured as described above, the following effects can be obtained.
（１）励磁コイル１１のアース側端部ｌｉｅを継鉄主部
１５と補助部材１６の圧入部に圧着挾持してボディアー

するという不具合を生ずることが無くなり信頼性が大幅
に向上する。(1) Body earthing is performed by crimp the earth side end lie of the excitation coil 11 to the press-fitting part of the yoke main part 15 and the auxiliary member 16, and in order to inject and mold the resin 19 into the succeeding iron, the body earthing is performed. The area is completely isolated from the outside atmosphere. Therefore, even if the electromagnetic clutch is exposed to a corrosive atmosphere such as salt, the body ground portion will not corrode and cause problems such as falling off or poor conduction, and reliability will be greatly improved.
（２）また、アース側端部１１ａを継鉄１４に直接ボデ
ィアースできるので、従来技術で用いていたアース端子

用いていたアース側グロメットも削除できる。(2) Furthermore, since the ground side end portion 11a can be body grounded directly to the yoke 14, the ground terminal used in the prior art becomes unnecessary. Further, since the ground side end portion 11a is fixed to the yoke 14 at the same time when the yoke auxiliary member 16 is press-fitted into the main member 15, a special process for body grounding is not required. In addition, there is no need to pull out the ground side end 11a to the outside of the yoke 14, and therefore, the ground side grommet used in the conventional technology to seal between the ground side end 11a and the ground pull-out hole of the yoke is also removed. can.
このように、励磁コイル１１を継鉄１４にボディアース
するために従来必要であった部品や工程を削減できるの
で、電磁クラッチを安価に生産できる。In this way, it is possible to reduce the number of parts and processes that were conventionally necessary for body-grounding the excitation coil 11 to the yoke 14, so that the electromagnetic clutch can be produced at low cost.
