Therefore, it is easy to reduce the number of cores when molding the resin case 3, and it is easy to mold the resin case 3.
Further, since the fixing portion 411 is formed on the metal cover 4, it is easy to secure the attachment strength of the electronic board 2.
　また、樹脂ケース３におけるコネクタ端子５は、樹脂ケース３と金属カバー４とが合わさることによって金属カバー４に固定された電子基板２のスルーホール２０の内壁２１に弾性的に接触する。それゆえ、制御装置１を製造する際、はんだ付け等することなく、電子基板２とコネクタ端子５とを容易に接続することができる。 Further, the connector terminal 5 in the resin case 3 elastically contacts the inner wall 21 of the through hole 20 of the electronic substrate 2 fixed to the metal cover 4 when the resin case 3 and the metal cover 4 are combined. Therefore, when the control device 1 is manufactured, the electronic board 2 and the connector terminal 5 can be easily connected without soldering or the like.
　また、制御装置１は、樹脂ケース３の外側は油中環境下に曝され、金属カバー４の外側は気中環境下に曝される状態で使用される。そして、かかる制御装置１の取付構造において、固定部４１１は金属カバー４に形成されている。それゆえ、樹脂ケース３に固定部４１１を形成した場合よりも、樹脂ケース３及び金属カバー４内への油の浸入を防止しやすい。ここで、樹脂ケース３に固定部４１１を形成した場合、電子基板２を固定部４１１にボルト１４で締結する際に生じる応力で、樹脂ケース３における固定部４１１周辺にクラックが生じ、このクラックを介して樹脂ケース３内に油が浸入するおそれが考えられる。一方、本実施形態においては、油中環境下に曝される樹脂ケース３に固定部４１１を形成せず、気中環境下に配された金属カバー４に固定部４１１を形成しているため、樹脂ケース３及び金属カバー４の内側空間への油の浸入を防ぎやすい。 Further, the control device 1 is used in a state where the outside of the resin case 3 is exposed to the environment in oil and the outside of the metal cover 4 is exposed to the environment in air. In addition, in the mounting structure of the control device 1, the fixing portion 411 is formed on the metal cover 4. Therefore, it is easier to prevent oil from entering the resin case 3 and the metal cover 4 than when the fixing portion 411 is formed on the resin case 3. Here, when the fixing portion 411 is formed in the resin case 3, the stress generated when the electronic board 2 is fastened to the fixing portion 411 with the bolt 14 causes a crack to occur around the fixing portion 411 in the resin case 3, and the crack is generated. It is conceivable that oil may enter the resin case 3 through the resin. On the other hand, in the present embodiment, since the fixing portion 411 is not formed on the resin case 3 exposed to the oil environment, the fixing portion 411 is formed on the metal cover 4 arranged in the air environment. It is easy to prevent oil from entering the space inside the resin case 3 and the metal cover 4.
　また、樹脂ケース３は、制御装置１外部のコネクタを接続するための装着部（第一～第四装着部３０２、３２２、３２３、３２４）を複数有する。また、樹脂ケース３は、コネクタ端子５を包囲する包囲壁（第一～第三包囲壁３１ａ、３１ｂ、３１ｃ）を複数有する。さらに、樹脂ケース３は、Ｚ方向に長尺なコネクタ体３０を中子としたインサート成形で形成される。それゆえ、樹脂ケース３の成形が複雑になりやすいが、本実施形態においては、前述のごとく電子基板２締結用の固定部４１１を金属カバー４に形成しているため、樹脂ケース３の成形を容易にしやすい。 Further, the resin case 3 has a plurality of mounting parts (first to fourth mounting parts 302, 322, 323, 324) for connecting a connector outside the control device 1. Further, the resin case 3 has a plurality of surrounding walls (first to third surrounding walls 31a, 31b, 31c) surrounding the connector terminal 5. Further, the resin case 3 is formed by insert molding using the connector body 30 elongated in the Z direction as a core. Therefore, although the molding of the resin case 3 is likely to be complicated, in the present embodiment, since the fixing portion 411 for fastening the electronic board 2 is formed on the metal cover 4 as described above, the molding of the resin case 3 is performed. Easy to make.
　以上のごとく、本実施形態によれば、樹脂ケースの成形を容易にすることができる制御装置を提供することができる。 As described above, according to this embodiment, it is possible to provide the control device that can facilitate the molding of the resin case.
　本発明は、前記各実施形態に限定されるものではなく、その要旨を逸脱しない範囲において種々の実施形態に適用することが可能である。 The present invention is not limited to the above-described embodiments, but can be applied to various embodiments without departing from the scope of the invention.
