本実施形態のシールカバー10は上記のような構造であって、例えば以下のような手順で組み付けられる。まずシール部材保持部材20のシール装着溝25に対してシール部材27が嵌着される。次に、シール部材保持部材20の位置決めピン35をピン挿通孔75に、ボス部33を挿通孔73に挿通しつつカバー本体60の後面にシール部材保持部材20を配する。   The seal cover 10 of the present embodiment has the above-described structure, and is assembled by the following procedure, for example. First, the seal member 27 is fitted into the seal mounting groove 25 of the seal member holding member 20. Next, the sealing member holding member 20 is disposed on the rear surface of the cover body 60 while the positioning pin 35 of the sealing member holding member 20 is inserted into the pin insertion hole 75 and the boss portion 33 is inserted into the insertion hole 73.

そして、タップネジ80をボス部33の下穴33Aに嵌め込んで締付ける。なお、タップネジ80がねじ込まれるボス部33が挿通する挿通孔73の周縁部である凹部71は後側に凹んでおり、その凹部71の高さに合わせてボス部33の突出高さも低く抑えられているため、タップネジ80のねじ込み後の突出寸法を小さくすることができる。   Then, the tap screw 80 is fitted into the pilot hole 33A of the boss portion 33 and tightened. In addition, the recessed part 71 which is the peripheral part of the insertion hole 73 in which the boss | hub part 33 in which the tap screw 80 is screwed is recessed in the back side, and the protrusion height of the boss | hub part 33 is also restrained low according to the height of the recessed part 71. Therefore, the protrusion dimension after screwing in the tap screw 80 can be reduced.

また、ボス部33の前端位置がカバー本体60の凹部71の前面位置よりも高くなっていることから、タップネジ80のねじ込みが完了した時点では、図7に示すように、リング部83がボス部33の前面に固定される一方で、リング部83とカバー本体60の凹部71との間にはボス部33の軸線方向(前後方向)の隙間ができる。そのため、シール部材保持部材20は、リング部83が挿通孔73の孔縁部に当たることでカバー本体60の裏面から落下することが阻止される一方で、カバー本体60の後面側においてボス部33の軸線方向に沿って移動可能に取り付けられた状態となる。また、ボス部33と挿通孔73との間、並びに位置決めピン35とピン挿通孔75との間にはクリアランスC1,C2が設けられていることで、シール部材保持部材20は全方位において移動可能な状態で保持されることになる。   Further, since the front end position of the boss portion 33 is higher than the front surface position of the concave portion 71 of the cover main body 60, when the screwing of the tap screw 80 is completed, as shown in FIG. While being fixed to the front surface of 33, a gap in the axial direction (front-rear direction) of the boss portion 33 is formed between the ring portion 83 and the concave portion 71 of the cover body 60. Therefore, the seal member holding member 20 is prevented from falling from the back surface of the cover body 60 when the ring portion 83 hits the edge of the insertion hole 73, while the boss portion 33 of the boss portion 33 is formed on the rear surface side of the cover body 60. It will be in the state attached so that movement was possible along an axial direction. Further, since the clearances C1 and C2 are provided between the boss portion 33 and the insertion hole 73 and between the positioning pin 35 and the pin insertion hole 75, the seal member holding member 20 can move in all directions. Will be held in the correct state.

このようにシールカバー10が組み付けられ後、図8に示すように、シールカバー10は、機器のケースの側面に設けられたコネクタ90の開口部91に被着される。シールカバー10を所定位置に配して、カバー本体60をコネクタ90側に向けて押圧すると、シール部材保持部材20は、シール部材25を周方向に潰し変形させつつ、開口部91内に押し込まれる。この際、シール部材保持部材20は全方位に移動可能な状態で保持されているから、開口部91との間で芯出しされつつ嵌合される。嵌合によってシール部材25が押し潰されることで、シール部材保持部材20と開口部91との間が水密状態にされ、コネクタ90内に水が浸入するのを抑制する。   After the seal cover 10 is assembled in this manner, as shown in FIG. 8, the seal cover 10 is attached to the opening 91 of the connector 90 provided on the side surface of the device case. When the seal cover 10 is disposed at a predetermined position and the cover body 60 is pressed toward the connector 90 side, the seal member holding member 20 is pushed into the opening 91 while the seal member 25 is crushed and deformed in the circumferential direction. . At this time, since the seal member holding member 20 is held in a state where it can move in all directions, the seal member holding member 20 is fitted to the opening 91 while being centered. The seal member 25 is crushed by the fitting, so that the space between the seal member holding member 20 and the opening 91 is in a watertight state, and water is prevented from entering the connector 90.

そして、カバー本体60の両端の取付板部69のボルト挿通孔69Aにボルトを通して、コネクタ90のブラケット93のボルト孔にねじ込むことで、シールカバー10がブラケット93と一緒に機器のケースの側面に固定される。このように固定されると、シールド性能を向上させるために、側面板部63の直線状の後端と下板部65の直線状の後端がコネクタ90の前面と当接する一方、水抜き孔77の部分は、カバー本体60とコネクタ90との間に隙間ができる。また、上板部67とコネクタ90との間には、切欠き部79やコネクタ90の曲げ等を回避するための隙間が設けられている。   Then, the seal cover 10 is fixed to the side surface of the case of the device together with the bracket 93 by passing the bolt through the bolt insertion hole 69A of the mounting plate portion 69 at both ends of the cover body 60 and screwing it into the bolt hole of the bracket 93 of the connector 90. Is done. When fixed in this manner, the straight rear end of the side plate 63 and the straight rear end of the lower plate 65 abut against the front of the connector 90 in order to improve the shielding performance, In the portion 77, a gap is formed between the cover main body 60 and the connector 90. In addition, a gap is provided between the upper plate portion 67 and the connector 90 to avoid bending of the notch 79 and the connector 90.

このようにシールカバー10がコネクタ90の開口部91に被着された状態で水がシールカバー10上にかかると、上板部67とコネクタ90との間の隙間や、切欠き部79から水が浸入する。図8の矢印Rで示すように、上方から浸入した水はシールカバー保持部材20の周縁壁部31の外周面をつたって、下板部65とコネクタ90との間に溜まる。この溜まった水は、下板部65の略中央付近にある水抜き孔77から排出される。   When water is applied onto the seal cover 10 with the seal cover 10 being attached to the opening 91 of the connector 90 in this way, the water from the gap between the upper plate portion 67 and the connector 90 or the notch 79. Invades. As indicated by an arrow R in FIG. 8, the water that has entered from above passes through the outer peripheral surface of the peripheral wall portion 31 of the seal cover holding member 20 and accumulates between the lower plate portion 65 and the connector 90. The accumulated water is discharged from a drain hole 77 in the vicinity of the approximate center of the lower plate portion 65.

このように、仮に上板部67とコネクタ90との間の隙間や、切欠き部79から水が浸入しても、下板部65とコネクタ90の間に設けられた水抜き孔77から排出されることになり、シールカバー10内に滞留することがなくなる。   In this manner, even if water enters the gap between the upper plate portion 67 and the connector 90 or the notch portion 79, the water is discharged from the drain hole 77 provided between the lower plate portion 65 and the connector 90. Therefore, it does not stay in the seal cover 10.
