A substantially first half portion of the main body portion 71 collectively surrounds a plurality (three) of fitting portions 52, and a substantially latter half portion of the main body portion 71 is externally fitted to the connecting portion 51 of the electric wire side housing 50. The main body 71 is assembled to the electric wire side housing 50 so as to surround substantially the latter half of the connecting portion 51 and the fitting portion 52. A terminal portion of a shield member 66 composed of a braided wire that collectively surrounds a plurality (three) of electric wires 64 is externally fitted to the outer periphery of a substantially latter half portion of the main body portion 71, and the shield member 66 is secured by a caulking ring 67. The main body 71 is fixed to be conductive. The shield member 66 and the electric wire 64 constitute a wire harness W. The flange-shaped attachment portion 72 is formed with a bolt hole (not shown) corresponding to a female screw hole (not shown) of the case 10 and a bolt hole (not shown) of the device side shield shell 40. Yes. Further, the shield member and the electric wire are covered with a metal or hard synthetic resin cover, and this cover is engaged with the electric wire side shield shell 70.
かかる電線側コネクタCbは、ケース10の外部において機器側コネクタCaに嵌合される。嵌合に際しては、各嵌合部52を、夫々、対応するフード部23及び嵌合凹部22内に嵌め込むことで、機器側ハウジング20と電線側ハウジング50が嵌合される。また、電線側シールドシェル70の取付部72を機器側シールドシェル40のフランジ部42の外面に面接触状態で当接させ、双方のボルト孔に通したボルトをケース10の雌ネジ孔に螺合することで、電線側シールドシェル70が機器側シールドシェル40を介してケース10に対して導通可能に固定される。以上により、コネクタCa,Cb同士の嵌合が完了する。嵌合状態では、機器側端子30の前端部30Fが電線側端子60の角筒部61内に進入し、角筒部61内の弾性接触片65と弾性接触し、もって、端子30,60同士が導通可能に接続される。また、ハウジング20,50同士の嵌合部分においては、機器側ハウジング20の円形孔24の内周と電線側ハウジング50の嵌合部52の外周との隙間が、電線側シール部材55により液密状態にシールされる。   The electric wire side connector Cb is fitted to the device side connector Ca outside the case 10. At the time of fitting, each fitting portion 52 is fitted into the corresponding hood portion 23 and fitting recess 22 to fit the device-side housing 20 and the wire-side housing 50. Further, the mounting portion 72 of the wire side shield shell 70 is brought into contact with the outer surface of the flange portion 42 of the device side shield shell 40 in a surface contact state, and the bolts passed through both bolt holes are screwed into the female screw holes of the case 10. By doing so, the electric wire side shield shell 70 is fixed to the case 10 through the device side shield shell 40 so as to be conductive. Thus, the fitting between the connectors Ca and Cb is completed. In the fitted state, the front end portion 30F of the device-side terminal 30 enters the rectangular tube portion 61 of the electric wire-side terminal 60 and makes elastic contact with the elastic contact piece 65 in the rectangular tube portion 61. Are connected in a conductive manner. Further, in the fitting portion between the housings 20 and 50, the gap between the inner periphery of the circular hole 24 of the device-side housing 20 and the outer periphery of the fitting portion 52 of the wire-side housing 50 is liquid-tight by the wire-side seal member 55. Sealed to state.
両コネクタCa,Cbを嵌合した状態では、取付孔11と機器側ハウジング20との隙間が機器側シール部材29によってシールされているので、ケース10の外面に沿った液体が取付孔11内に浸入することが阻止される。また、外部から機器側ハウジング20と機器側シールドシェル40との隙間、又は機器側シールドシェル40と電線側シールドシェル70との隙間を通って機器側ハウジング20のフード部23の外周まで入り込んだ液体は、電線側シール部材55によりフード部23内(端子30,60同士の接続部分)への浸入を阻止される。電線側ハウジング50と電線側シールドシェル70との隙間に入り込んだ液体も、電線側シール部材55により、フード部23内(端子30,60同士の接続部分)への浸入を阻止される。   In a state where both the connectors Ca and Cb are fitted, the gap between the mounting hole 11 and the device-side housing 20 is sealed by the device-side seal member 29, so that liquid along the outer surface of the case 10 enters the mounting hole 11. Intrusion is prevented. Further, liquid that has entered from the outside to the outer periphery of the hood portion 23 of the device-side housing 20 through the gap between the device-side housing 20 and the device-side shield shell 40 or through the gap between the device-side shield shell 40 and the wire-side shield shell 70. Is prevented from entering the inside of the hood portion 23 (connection portion between the terminals 30 and 60) by the electric wire side sealing member 55. The liquid that has entered the gap between the electric wire side housing 50 and the electric wire side shield shell 70 is also prevented from entering the hood portion 23 (the connection portion between the terminals 30 and 60) by the electric wire side sealing member 55.
一方、ケース10内に貯留されている液体(例えば、オイル等)が取付孔11と機器側ハウジング20との隙間に入り込んだ場合、その液体は、機器側ハウジング20とケース10の外面との間に設けられている機器側シール部材29により、ケース10の外部への漏出を阻止される。したがって、機器側コネクタCaから電線側コネクタCbを外した状態においても、ケース10内の液体が取付孔11と機器側ハウジング20との隙間を通って外部へ漏出することはない。   On the other hand, when liquid (for example, oil) stored in the case 10 enters the gap between the mounting hole 11 and the device-side housing 20, the liquid is between the device-side housing 20 and the outer surface of the case 10. Leakage to the outside of the case 10 is prevented by the device side seal member 29 provided in the case 10. Therefore, even when the electric wire side connector Cb is removed from the device side connector Ca, the liquid in the case 10 does not leak outside through the gap between the mounting hole 11 and the device side housing 20.
上述のように本実施形態においては、機器Mのケース10の外面を伝って取付孔11からケース10の内部に至る経路での浸水、及びこれとは逆の経路での漏水は、機器側ハウジング20とケース10の外面との間に介在させた機器側シール部材29によって阻止される。また、電線側コネクタCbを機器側コネクタCaから外した状態では、機器側ハウジング20と機器側シールドシェル40との隙間が、機器側シール部材29によってケース10の内部から液密状に隔絶されているので、機器側シールドシェル40と機器側ハウジング20との隙間を介してケース10の内外を連通させる経路は防水される。このように機器側シール部材29が、2つの経路を防水する機能を兼ね備えているので、部品点数が増えずに済んでいる。   As described above, in the present embodiment, water in the path from the mounting hole 11 to the inside of the case 10 through the outer surface of the case 10 of the apparatus M, and water leakage in the path opposite to this, It is blocked by a device-side sealing member 29 interposed between 20 and the outer surface of the case 10. Further, in a state where the wire side connector Cb is removed from the device side connector Ca, the gap between the device side housing 20 and the device side shield shell 40 is isolated from the inside of the case 10 in a liquid-tight manner by the device side seal member 29. As a result, the path connecting the inside and the outside of the case 10 through the gap between the device-side shield shell 40 and the device-side housing 20 is waterproofed. Thus, since the apparatus side sealing member 29 has the function which waterproofs two paths, it does not need to increase the number of parts.
また、機器側シールドシェル40が、薄板状に比べて変形し難いアルミダイキャスト製とされ、その機器側シールドシェル40の押圧部41が、機器側ハウジング20を全周に亘ってケース10の外面側へ押圧しているで、機器側シール部材29が機器側ハウジング20とのケース10との間で強固に挟み付けられることとなり、機器側シール部材29によるシール性能の信頼性が高い。   In addition, the device-side shield shell 40 is made of aluminum die cast which is not easily deformed as compared to a thin plate shape, and the pressing portion 41 of the device-side shield shell 40 extends around the device-side housing 20 on the outer surface of the case 10. Since the device side sealing member 29 is firmly sandwiched between the device side housing 20 and the case 10, the reliability of the sealing performance by the device side sealing member 29 is high.
