Description

【０００１】
【発明の属する技術分野】
本発明は、例えばテレビのアンテナ線や電話線などの電線を屋外から屋内に入線するための入線プレートに関するものである。
【０００２】
【従来の技術】
従来の入線プレートは、図２０（ａ）〜（ｃ）に示すように、屋外側の電線を屋内に引き込む造営面に設けられた挿通孔の屋外側に連通して電線を挿通する開口窓７１を有し、造営面に取り付けられる略矩形平板状の取付枠７０と、外周の縁が造営面に当接するように取付枠７０の前面に取り付けられ、取付枠７０の開口窓７１と連通して電線を挿通する挿通孔８１が形成された可撓性を有する合成樹脂製の防水パッキン８０と、防水パッキン８０を挟んで取付枠７０の前面側に取り付けられ、前方に突出する膨出部９１が一体に形成された合成樹脂製のカバー９０と、カバー９０の前面下部に設けられた略Ｌ字状のコード押え部９２とからなる（実開昭６３−１８７５２２号公報，特開平６−１４１４３８号公報，特開昭６２−２９６７２０号公報，特開昭６０−２４５４１５号公報参照）。
【０００３】
取付枠７０は、略中央部に形成された開口窓７１と、開口窓７１の上部及び下部に形成され、取付枠７０を造営面に固定する皿ネジ用のネジ挿通孔７２，７２と、ネジ挿通孔７２，７２よりもさらに取付枠７０の上端及び下端側に形成され、内部にナット７３ｂ，７３ｂが配設されたカバー９０取付用の貫通穴７３，７３とを有している。
【０００４】
カバー９０に形成された膨出部９１の下部には、取付枠７０に略垂直な略楕円状の開口部９３が形成され、開口部９３と防水パッキン８０の挿通孔８１が内部で連通している。また、この開口部９３には、略十字状の溝９４ａを２つ備えた可撓性を有する合成樹脂製のブッシング部９４が取り付けてある。さらに、カバー９０前面の上端側及び下端側のそれぞれの略中央部には、取付枠７０の貫通穴７３，７３と連通してカバー９０を取付枠７０にネジ止めするネジ挿通孔９５，９５が形成されている。
【０００５】
コード押え部９２は、ネジ止め用のネジ挿通孔（図示せず）を有して、カバー９０前面から略垂直に配設される柱部９２ａと、柱部９２ａの先端から略垂直に突出する押え片９２ｂとからなり、図２１に示すように、ネジ９２ｃを柱部９２ａの図示しないネジ挿通孔
ならびにカバー９０に形成された透孔９７に挿通し、カバー９０の背面側のナット９８に螺着することによって、カバー９０に固定される。
【０００６】
上述のような入線プレートを造営面に取り付けるときは、造営面に配置された取付枠７０のネジ挿通孔７２，７２にそれぞれ図示しない皿ネジを挿通して造営面に螺着し、取付枠７０を造営面に固定する。次に、防水パッキン８０を取付枠７０に被せ、防水パッキン８０を取付枠７０と挟むように取付枠７０の前面にカバー９０を配置し、カバー９０の各ネジ挿通孔９５ならびに取付枠７０の貫通穴７３にネジ７３ａを挿通して、図２２に示すように、取付枠７０の背面側のナット７３ｂに螺着させることによって、カバー９０が取付枠７０に固定される。このカバー９０を取付枠７０に固定するときには、カバー９０の背面外周にそって造営面側に突出した突出部９６が防水パッキン８０の前面外周に沿って設けられた溝８２に嵌め込まれ、ネジ７３ａ，７３ａの締め付けによって、突出部９６が防水パッキン８０の溝８２を押圧して防水パッキン８０の縁が造営面に押し付けられるようにしている。
【０００７】
電線は、図２０（ｂ）に示すブッシング部９４の何れかの溝９４ａを通ってカバー９０の膨出部９１内に引き込まれるとともに、ブッシング部９４に支持され、さらにカバー９０の背面側から防水パッキン８０に形成された挿通孔８１ならびに取付枠７０の開口窓７１を通って造営面の挿通孔から屋内に引き込まれる。また、屋外側の電線は、コード押え部９２の押え片９２ｂとカバー９０前面の間に挟まれ、柱部９２ａに取り付けられるネジ９２ｃを締め付けることによって、押え片９２ｂにカバー９０前面へ押し付けられて支持され、屋外側の電線の張力がカバー９０の膨出部９１内から屋内側の電線に伝わらないようにしている。
【０００８】
このように取り付けられた入線プレートは、例えば屋外側の造営面に降り注ぎ、また造営面を流下する雨水などの水が造営面の挿通孔に浸入するのを防水パッキン８０によって防いでいる。
【０００９】
【発明が解決しようとする課題】
しかしながら、このような入線プレートを組立てるときには、取付枠７０にカバー９０を取り付けるためのネジ７３ａ，７３ａを必要とすることによって、部品点数が多くなり、組立作業が煩雑になるといった問題と、これらのネジ７３ａ，７３ａの先端部が前面側に露出していることにより、見栄えが悪くなるといった問題があった。
【００１０】
本発明は上記問題点の解決を目的とするものであり、組立用のネジを用いずに部品点数を少なくして組立作業性を向上するとともにコスト低減を図り、見栄えを良くした入線プレートを提供する。
【００１１】
【課題を解決するための手段】
上記目的を達成するために、請求項１の発明は、造営面に設けられた電線を挿通する挿通孔と連通して電線を通す入線穴、入線穴と外部とに通じて少なくとも電線の幅寸法より広く形成された連通部を有し、造営面に配設される略平板状のボディと、連通部を塞いでボディに着脱自在に取り付けられる固定片と、ボディ及び固定片の前面を覆うカバーと、ボディの造営面と略対向する背面の周縁に沿ってボディと造営面の間に配置される防水パッキンとを備え、ボディ前面に隙間を開けて略対向するカバー取付用のリブをボディに形成するとともに、カバーをボディ前面に沿ってスライドさせてボディ前面とカバー取付用のリブとの隙間に嵌め込まれるリブをカバーに設けた入線プレートであって、カバーは、略矩形状の主部と、カバーのスライド方向での主部の一端を除く周縁に沿って背面側に突出する側壁と、側壁が形成されていない主部の周縁に沿うように内側に形成され側壁よりも低く背面側に突出する底壁とから、背面側が開口した略箱状に形成され、底壁と略対向する一端側の両側部内側に突設され他端側に傾斜を有しカバーのスライド方向に略垂直な方向からボディの一部を挟み込む１対のガイド片と、底壁と略対向する一端側の側壁の縁に沿って内側に突出する１対の突片とを有して、突片の間には位置決め用の凹部が形成され、ボディは、略平板状のベースと、ベースの前面周縁に沿って略垂直に突出する周壁を有し、カバーのスライド方向におけるボディの一端側にある周壁の外側には、略垂直に突出しカバーをボディに取り付けたときにカバーの位置決め用の凹部に対してカバーのスライド方向に嵌合する位置決め用のリブを設けたことを特徴とし、カバーのリブをボディ前面とカバー取付用のリブとの隙間に嵌め込むようにカバーをボディ前面に沿ってスライドさせることによって、カバーをボディに着脱自在に取り付けることができる。その結果、従来例のように組立用のネジを必要としないため部品点数を少なくして組立作業性を向上させることができるとともにコスト低減を図ることができ、ネジの先端部などが露出しないので見栄えを良くすることができる。また、カバーをボディ前面に沿ってスライドさせてボディに取り付けたとき、位置決め用の凹部及び突起が互いに嵌合することによって、カバーのスライド方向に略垂直な方向のボディに対する位置決めを行うことができるとともに、がたつきを抑えることができる。さらに、カバーのガイド片がボディの一部を挟み込むことによって、カバーをスライドさせるときには、カバーはボディ前面に沿ってガイドされ、カバーをボディに取り付けたときには、カバーのスライド方向に略垂直な方向のボディに対するがたつきを抑えることができる。
【００１２】
請求項２の発明は、請求項１の発明において、ボディ前面の入線穴周辺に、挿通孔との位置合わせ用の目印を１乃至複数個設けたことを特徴とし、位置合わせ用の目印を設けたことによって、目印を目安にしてボディの入線穴が造営面の挿通孔に連通するようにボディを造営面に容易に位置合わせして配設することができる。
【００１３】
請求項３の発明は、請求項１又は２の発明において、ボディと防水パッキンを２色成形したことを特徴とし、部品点数を少なくして組立作業性を向上させることができる。
【００１４】
請求項４の発明は、請求項１〜３の何れかの発明において、防水パッキンをボディに熱着して固定したことを特徴とし、防水パッキンをボディに例えば接着剤などで固定したときと比べて、固定強度のばらつきをなくして品質を安定させることができる。
【００１５】
請求項５の発明は、請求項１〜４の何れかの発明において、ボディまたは固定片の少なくとも一方の背面に、造営面に当接する撓み防止用のリブを突設したことを特徴とし、ボディ及び固定片を造営面に配設するとき、撓み防止用のリブが造営面に当接することによって、ボディ又は固定片の少なくとも一方の撓みを規制することができ、その結果、防水パッキンと造営面との間に隙間が生じるのを防止することができる。
【００１６】
請求項６の発明は、請求項１〜５の何れかの発明において、ボディ前面に隙間を開けて略対向し、固定片をボディ前面に沿ってスライドさせてボディ前面との隙間に固定片の両側部を嵌め込む固定片取付用のリブをボディに形成し、固定片のスライド方向に略垂直な方向に嵌合する凹部及び突起を、ボディ及び固定片のそれぞれの取付面に設けたことを特徴とし、ボディ及び固定片のそれぞれの取付面に互いに嵌合する凹部及び突起を設けたことによって、固定片の両側部をボディ前面と固定片取付用のリブとの隙間に嵌め込んで固定片をボディにスライドさせて取り付けるとき、突起がボディ又は固定片の何れか一方の取付面を押圧してスライド方向に対する抵抗力が増し、固定片を取り付けたときには、突起が凹部に嵌合してクリック感を得ることができ、その結果、施工を確実に行うことができる。
【００１７】
請求項７の発明は、請求項６の発明において、固定片の両側辺のスライド方向先端側に傾斜を設けたことを特徴とし、固定片の両端部をボディ前面と固定片取付用のリブとの隙間に嵌め込み易くすることができ、固定片の取付作業性を向上させることができる。
【００１８】
請求項８の発明は、請求項６又は７の発明において、ボディ及び固定片取付用のリブを樹脂成形品とし、固定片取付用のリブを成形する金型用の開口部がボディの要所に設けられたことを特徴とし、ボディ及び固定片取付用のリブを金型にて一体に成形することができ、しかもスライドコア金型を用いずに、コア金型およびキャビティ金型のみ用いて成形することができることによって、金型費用を抑えることができる。
【００１９】
請求項９の発明は、請求項１〜８の何れかの発明において、ボディ及びカバー取付用のリブを樹脂成形品とし、カバー取付用のリブを成形する金型用の開口部がボディの要所に設けられたことを特徴とし、ボディ及びカバー取付用のリブを金型にて一体に成形することができ、しかもスライドコア金型を用いずに、コア金型およびキャビティ金型のみ用いて成形することができることによって、金型費用を抑えることができる。
【００２０】
請求項１０の発明は、請求項１〜９の何れかの発明において、カバーのスライド方向に略垂直な方向に嵌合する凹部及び突起を、ボディ及びカバーのそれぞれの取付面に設けたことを特徴とし、ボディ及びカバーのそれぞれの取付面に互いに嵌合する凹部及び突起を設けたことによって、カバーのリブをボディ前面とカバー取付用のリブとの隙間に嵌め込んでカバーをボディにスライドさせて取り付けるとき、突起がボディ又はカバーの何れか一方の取付面を押圧してスライド方向に対する抵抗力が増し、カバーを取り付けたときには、突起が凹部に嵌合してクリック感を得ることができ、その結果、施工を確実に行うことができる。
【００２１】
請求項１１の発明は、請求項１〜１０の何れかの発明において、造営面の挿通孔に挿通する電線が通される開口部を、固定片の周部およびカバーの周部にまたがって形成し、開口部を形成する固定片の周部にノックアウトを設けたことを特徴とし、開口部を形成する固定片の周部に設けられたノックアウトを切り取ることによって、造営面の挿通孔に挿通する電線の外形に合わせて施工することができ、従来例のブッシング部を削除して部品点数を減らし、組立作業性を向上することができるとともに、コスト低減を図ることができる。
【００２２】
請求項１２の発明は、請求項１〜１１の何れかの発明において、ボディの背面に入線穴を囲むように水滴浸入防止用のリブを突設したことを特徴とし、水滴浸入防止用のリブを設けたことによって、例えばボディ背面に入り込んだ水滴が、造営面の挿通孔に浸入するのを防止することができる。
【００２３】
請求項１３の発明は、請求項１〜１２の何れかの発明において、カバーのスライド方向のカバー取付用のリブの長さを、ボディの幅の略１／２よりも短くしたことを特徴とし、カバーをボディに取り付けるとき、ボディの一端側からカバーのリブをボディ前面とカバー取付用のリブとの隙間に嵌め込んでカバーをスライドさせることなく、ボディの中央付近からカバーをスライドして取り付けることができて、スライド量を少なくすることができ、その結果、例えばカバーのスライド方向のボディ一端側周辺の造営面が突出していたときにでも、カバーを造営面に干渉されることなくボディに取り付けることができる。
【００２４】
【発明の実施の形態】
（実施形態１）
本実施形態は、図１に示すように、造営面１に設けられた挿通孔１ａと連通して屋外側の電線２を屋内に引き込む入線穴２３ａが略中央部に設けられるとともに、長手方向の一端側の外部と入線穴２３ａを連通する連通部２３ｂが形成され、屋外側の造営面１に配設される略平板状に形成された合成樹脂製のボディ２１と、ボディ２１の連通部２３ｂを塞ぐように略矩形平板状に形成された合成樹脂製の固定片２２と、ボディ２１及び固定片２２の前面を覆う合成樹脂製のカバー３０と、ボディ２１の造営面１と略対向する背面の周縁に沿ってボディ２１と造営面１の間に配置される略コ字状に形成された合成樹脂製の防水パッキン１０とから成る。
【００２５】
ボディ２１は、図２（ａ），（ｂ）に示すように、入線穴２３ａと連通部２３ｂが形成された略平板状のベース２３の前面周縁に沿って略垂直に突出する略コ字状の周壁２４を有し、連通部２３ｂが形成されていないボディ２１の一端と、他端側の両側部とにある周壁２４前面側の縁に沿った外側には、ベース２３前面との間に隙間を開け、ベース２３と略平行な方向に突出する略矩形平板状のカバー取付用のリブ２４ａ，２４ａ，２４ａが形成されている。そして、ボディ２１の連通部２３ｂが形成された一端側に形成される一対のカバー取付用のリブ２４ａ，２４ａの長手方向の長さは、ボディ２１の長手方向の長さの略１／２以下とし、ベース２３のカバー取付用のリブ２４ａ，２４ａに略対向する部位には開口部４１，４１を形成している。
【００２６】
また、ボディ２１の連通部２３ｂが形成されている一端側にある周壁２４の内側には、ベース２３前面との間に隙間を開け、ベース２３と略平行な方向に突出する略矩形平板状の固定片取付用のリブ４２，４２が設けられている。そして、上述のカバー取付用のリブ２４ａと同様に、ベース２３の固定片取付用のリブ４２，４２に略対向する部位には開口部４２ａ，４２ａを形成している。
【００２７】
このような、ベース２３の開口部４１，４１，４２ａ，４２ａは、それぞれカバー取付
用ならびに固定片取付用のリブ２４ａ，２４ａ，４２，４２を成形するときの金型用に開口されたものである。それぞれの開口部４１，４１，４２ａ，４２ａに対応する部位にベース２３に略垂直な方向からコア金型を通して、コア金型とキャビティ金型を用いてカバー取付用のリブ２４ａ，２４ａ及び固定片取付用のリブ４２，４２をベース２３及び周壁２４と一体に成形することができる。故に、スライドコア金型を必要としないので、金型費用を抑えることができる。
【００２８】
またさらに、ベース２３背面には、周縁に沿って略垂直に造営面１側へ突出する防水パッキン取付用の取付壁２５が設けられ、ベース２３の長手方向の連通部２３ｂが形成されていない一端側には、前面に背面よりも大きな開口を有して、周辺部が背面側に突出した略楕円状のボス穴２６が形成されている。
【００２９】
防水パッキン１０は可撓性を有する合成樹脂から、ボディ２１の連通部２３ｂを除く周縁に沿うように形成され、前面にはボディ２１の取付壁２５が嵌め込まれる溝１１が設けられている。この防水パッキン１０は、造営面１を流下する雨水などの水が造営面１の挿通孔１ａへ浸入するのを防止する。
【００３０】
固定片２２は、図３に示すように、ボディ２１の連通部２３ｂを塞ぐように略矩形平板状に形成され、一端側の縁に沿うように前面から略垂直に突出する板片２８と、板片２８が形成された一端側の辺に沿って背面から造営面１側に突出する突出部２２ａとを有する。また、固定片２２の略中央部にはボス穴２６が形成され、板片２８の前面側の縁の略中央部には、電線２が配置される略半円状の凹部２８ａが凹設され、さらに、板片２８の凹部２８周辺は、板厚を薄くしてノックアウト部４４を形成している。
【００３１】
ところで、固定片２２には、図４に示すように、板片２８及び突出部２２ａの突出方向に互いに対向する部位がないように形成されているため、固定片２２をスライドコア金型を用いることなく一体に成形することができるようにしている。
【００３２】
このような固定片２２をボディ２１に取り付けるときには、図５に示すように、固定片２２を板片２８が形成されていない一端側からボディ２１のベース２３前面と固定片取付用のリブ４２との隙間に固定片２２の両側部を嵌め込んで、ボディ２１の連通部２３ｂに図５中下方から上方にスライドさせて挿入する。これによりボディ２１の連通部２３ｂは、図６（ａ）に示すように、固定片２２によって塞がれる。また、固定片２２の両側辺のスライド方向の先端側は、傾斜を有していることによって、固定片２２の嵌め込みを容易にしている。
【００３３】
カバー３０は、図１に示すように、略矩形状の主部３３と、主部３３の一端を除く周縁に沿って背面側に突出する側壁３６と、側壁３６が形成されていない主部３３の周縁に沿うように内側に形成され、側壁３６よりも低く背面側に突出する底壁３２とから、背面側が開口した略箱状に形成されている。
【００３４】
このカバー３０は、図６（ｂ）に示すように、底壁３２と略対向する一端側の両側部内側に突設され、他端側に傾斜を有する１対のガイド片４５，４５と、底壁３２と略対向する一端側の側壁３６の縁に沿って内側に突出する１対の突片４６，４６とを有して、突片４６，４６との間には位置決め用の凹部４６ａが形成される。また、カバー３０の両側にある側壁３６の縁に沿った内側には、それぞれ略矩形平板状のリブ３１，３１が突設され、図７（ａ）に示すように、それぞれのリブ３１の主部３３と略対向する面には凹部３１ａを設けている。
【００３５】
このカバー３０を図６（ａ）及び図７（ｂ）に示すボディ２１に取り付けるときには、ボディ２１のカバー取付用のリブ２４ａとベース２３前面との隙間に、カバー３０のリブ３１をボディ２１のボス穴２６が形成された一端側から嵌め込んで、カバー３０をボディ２１の前面に沿って連通部２３ｂ側へスライドさせる。このとき、カバー３０の１対のガイド片４５，４５の傾斜面がボディ２１の周壁２４に当接することによってカバー３０はガイドされ、カバー３０を取り付けたときには、１対のガイド片４５，４５が周壁２４を挟み込むため、カバー３０のスライド方向と略垂直な方向のがたつきを抑えることができる。さらに、ボディ２１のボス穴２６が形成された一端側にある周壁２４の外側には略垂直に突出する位置決め用のリブ４６ｂが設けられているため、カバー３０を取り付けたときには、この位置決め用のリブ４６ｂがカバー３０の位置決め用の凹部４６ａに嵌合され、カバー３０のスライド方向に略垂直な方向のボディ２１に対する位置決めを行うことができるとともに、ガイド片４５，４５と同様、がたつきを抑えることができる。そしてさらに、図６及び図７に示すように、ボディ２１の両側部にある１対のカバー取付用のリブ２４ａ，２４ａの背面側には、それぞれ突起２４ｃが形成されていることにより、カバー３０をスライドさせているときには、この突起２４ｃがカバー３０の１対のリブ３１，３１をベース２３側へ押圧してスライド方向に対する抵抗力を生じさせるが、ボディ２１に取り付けたときには、突起２４ｃ，２４ｃがカバー３０の凹部３１ａ，３１ａに嵌合されてクリック感を出すことができ、その結果、施工を確実に行うことができる。
【００３６】
上述のような入線プレートを造営面１に取り付けるときは、まずボディ２１の取付壁２５を防水パッキン１０の溝１１に嵌め込んでボディ２１に防水パッキン１０を取り付け、図８に示すように、造営面１に設けられた挿通孔１ａに挿通され下方に垂らされた屋外側の電線２が、ボディ２１の連通部２３ｂから入線穴２３ａに導入されるように、ボディ２１を造営面１に沿って動かすとともに、入線穴２３ａが挿通孔１ａと連通するようにボディ２１を配置する。このとき、入線穴２３ａ周辺のベース２３前面には、入線穴２３ａの略中心を指し示す３つの略三角形状の目印４３，４３，４３を設けているので、この３つの目印４３，４３，４３を目安とすることによって、挿通孔１ａを入線穴２３ａの略中央部に容易に位置合わせすることができる。
【００３７】
次に、固定片２２を上述のようにボディ２１の連通部２３ｂに差し込み、ボディ２１に取り付ける。そして、ボディ２１及び固定片２２に形成されたボス穴２６，２６にネジ４７，４７を挿通し、造営面１に螺着してボディ２１及び固定片２２を造営面１に固定するとともに、電線２を板片２８の凹部２８ａに配置する。
【００３８】
なお、固定片２２の突出部２２ａは、造営面１に当接して防水パッキン１０とともに、ボディ２１及び固定片２２の外周縁を囲んで外部からのボディ２１背面側への水滴の浸入を防ぐことができる。
【００３９】
最後に、ボディ２１のカバー取付用のリブ２４ａとベース２３前面との隙間に、カバー３０の側壁３６に設けられたリブ３１を嵌め込み、カバー３０を底壁３２側からボディ２１の前面に沿って、図１中上方から下方へスライドさせ、カバー３０をボディ２１に取り付ける。
【００４０】
ところで、本実施形態とは別に例えば図１０に示す入線プレートが考えられている。この入線プレートは、図９に示すように、本実施形態と同様、入線穴２３ａ’及び連通部２３ｂ’が形成されたボディ２１’と、連通部２３ｂ’を塞ぐ固定片２２’と、ボディ２１’及び固定片２２’の前面を覆うカバー３０’と、ボディ２１’の造営面１と略対向する背面の周縁に沿ってボディ２１’と造営面１の間に配置される防水パッキン１０とから成る。
【００４１】
しかし、本実施形態と異なって、周壁２４の前面側の略全ての縁に沿って複数個のカバー取付用のリブ２４ａ’が形成され、ベース２３’のカバー取付用のリブ２４ａ’の略対向する部位には本実施形態の開口部４１のような開口部が形成されていない。さらに、固定片２２’の両側辺にはそれぞれ溝２７が設けられており、ベース２３’の連通部２３ｂ’周辺部を固定片２２’の溝２７，２７に嵌め込んで固定片２２’をボディ２１’に取り付けるようにしている。
【００４２】
この場合、ボディ２１’のベース２３’に開口部が形成されていないことと、固定片２２’の両側辺に溝２７，２７が設けられていることによって、ボディ２１’及び固定片２２’を成形するときにはコア金型及びキャビティ金型以外にもスライドコア金型を必要とし、本実施形態と比較して金型費用が多くなってしまうこととなる。
【００４３】
さらに、複数個のカバー取付用のリブ２４ａ’が周壁２４の前面側の略全ての縁に沿って形成されているので、造営面１に取り付けられたボディ２１’にカバー３０’を取り付けるときには、ボディ２１’のカバー取付用のリブ２４ａ’とベース２３’前面との間にカバー３０’のリブ（図示せず）を嵌め込むために、ボディ２１’の長手方向のボス穴２６が形成された一端側に、カバー３０’をボディ２１’の長手方向に沿うように略一直線
状に配置する必要がある。また、図１１に示すようにボディ２１のボス穴２６が形成された一端と両側部とにある周壁２４の前面側の全ての縁に沿ってそれぞれカバー取付用のリブ２４ａ’’，２４ａ’’，２４ａ’’が形成された場合でも同様に、カバー３０をボディ２１の長手方向に略一直線状に配置する必要がある。このような場合には、例えば図１２に示すように、ボディ２１の上方周辺の造営面１が突出していると、この突出した造営面１が邪魔になって上述のようにカバー３０をボディ２１に対して配置することができず、カバー３０を取り付けることができない。
【００４４】
しかし、本実施形態では前述のようにボディ２１の両側部のカバー取付用のリブ２４ａ，２４ａをボディ２１の下端側にのみ形成し、その長さをリブ２４ａ’’の長さの略１／２にしていることにより、図１３に示すように、ボディ２１前面のボス穴２６が形成されている上部半分側にカバー３０の底壁３２が形成されている下部半分側をボディ２１及びカバー３０の長手方向に沿って重ね合わせた状態から、カバー取付用のリブ２４ａとベース２３前面との隙間にカバー３０のリブ３１を嵌め込みことができる。その結果、ボディ２１周辺の造営面１が突出している場合でも、カバー３０を造営面１に干渉されることなくボディ２１に取り付けることができる。
【００４５】
カバー３０をボディ２１に取り付けて、図１４（ａ）〜（ｃ）に示す入線プレートが完成する。そして図１４（ｃ）に示すように、カバー３０の底壁３２に凹設された略矩形状の凹所３２ａに、固定片２２の板片２８が嵌め込まれて底壁３２の凹所３２ａ周辺と板片２８の凹部２８ａ周辺とから開口部３が形成される。屋外側の電線２は、図１５に示すように、この開口部３からカバー３０及びボディ２１並びに固定片２２で囲まれた内部に導入され、さらにボディ２１の入線穴２３ａ及び造営面１の挿通孔１ａを通って屋内側に引き込まれる。また、電線２は、固定片２２の凹部２８ａ及びカバー３０の凹所３２ａのそれぞれの周辺部に当接して支持される。
【００４６】
また、電線２が開口部３に挿通できないような大きな幅寸法であっても、固定片２２の板片２８に設けられたノックアウト部４４を切り取ることによって、開口部３を大きくして電線２を挿通することができる。このように、開口部３の大きさを電線２の外形寸法に合わせることができることによって、従来例のようなブッシング部９４およびコード押え部９２を用いることなく、部品点数を少なくして組立性を向上させることができる。さらに、カバー３０のリブ３１，３１をボディ２１のカバー取付用のリブ２４ａ，２４ａとベース２３前面との隙間に嵌め込んでカバー３０をボディ２１の前面に取り付けることによって、従来例のように組立用のネジ７３ａ，７３ａを用いることなく、部品点数をさらに少なくして組立性を向上させることができ、コスト低減を図ることができる。また、ネジを用いていないことによって、見栄えを良くすることができる。
【００４７】
ところで図１６（ａ）〜（ｃ）に示すように、ボディ２１と防水パッキン１０とを２色成形しても良い。このときには、さらに部品点数を減らすことができ、組立の作業性をさらに向上させることができる。
（実施形態２）
本実施形態における基本構成は実施形態１と共通するために共通する部分については同一の符号を付して説明を省略し、本実施形態の特徴となる部分についてのみ詳細に説明する。
【００４８】
本実施形態では、図１７（ａ）〜（ｃ）に示すように、ボディ２１のベース２３背面の連通部２３ｂを挟み込む部位に、造営面１側に突出してボディ２１の厚みを増す略枠状の１対の補強用リブ４９，４９を設けている。この１対の補強用リブ４９，４９を形成したことによって、固定片２２のボス穴２６にネジ４７を挿通して造営面１に螺着するとき、補強用リブ４９，４９が造営面１に当接して、ネジ４７の締め付けによるボディ２１の撓みを抑え、防水パッキン１０と造営面１との間に隙間が生じるのを防止することができる。
【００４９】
また、防水パッキン１０をボディ２１に熱着して固定している。この熱着による固定を行うには、図１７（ａ）に示すように、ボディ２１背面側の四隅の４箇所に、造営面１側に突出する熱着用の突起５１ａを設け、突起５１ａのそれぞれを防水パッキン１０に形成される貫通穴５１ｂに挿通して防水パッキン１０を取付壁２５に取り付ける。そして、貫通穴５１ｂから突出する熱着用の突起５１ａの先端を熱で溶融することによってかしめ、防水パッキン１０をボディ２１に固定する。このように熱着により固定した場合、接着剤で固定するのと比べて固定強度のばらつきを抑えることができ、品質を安定させることができる。
【００５０】
さらに、図１７（ａ）に示すように、ボディ２１の突起２４ｃ及びカバー３０の凹部３１ａと同様にクリック感を出すため、ボディ２１の１対の固定片取付用のリブ４２，４２が形成されている周壁２４の内側に、略半円球状の突起４８を形成するとともに、固定片２２の両側辺に、固定片２２がボディ２１に取り付けられたときに突起４８に嵌合する凹部４８ａを凹設しても良い。
【００５１】
このような突起４８と凹部４８ａにより、図１８に示すように、固定片２２の両側部をボディ２１のベース２３前面と固定片取付用のリブ４２との隙間に嵌め込むときには、ボディ２１の突起４８が固定片２２の両側辺のスライド方向先端側に形成されている傾斜面と当接して固定片２２のスライド方向に対する抵抗力が増すが、固定片２２が取り付けられたときには、突起４８が凹部４８ａに嵌合して、クリック感を出すことができ、その結果、施工を確実に行うことができる。
【００５２】
ところで、図１９（ａ）（ｂ）に示すように、ボディ２１のベース２３背面に、入線穴２３ａを囲むように造営面１側に突出する水滴浸入防止用リブ５０を設けても良い。この場合には、例えば、ボディ２１のボス穴２６が形成された一端側から造営面１を伝って流下する水滴が、防水パッキン１０と造営面１との隙間を通ってボディ２１の背面と造営面１との間に入り込んでも、水滴浸入防止用リブ５０によって、造営面１の挿通孔１ａに浸入するのを防止することができる。
