【0005】
そして、筐体本体に配線金具やカバー体を組み合わせる工程においては、筐体本体の向きを確認して所定の方向に揃えることが必要であるが、ほぼ対称形状に形成された筐体本体の向きの確認は必ずしも容易でなく、自動化による製造コストの低減が容易でない問題を有している。
【0006】
【発明が解決しようとする課題】
上記のように、筐体本体に配線金具やカバー体を組み合わせる工程においては、筐体本体の向きを確認して所定の方向に揃えることが必要であるが、ほぼ対称形状に形成された筐体本体の向きの確認は必ずしも容易でなく、自動化による製造コストの低減が容易でない問題を有している。
【0007】
本発明は、このような点に鑑みなされたもので、組み立ての作業性を良好にできる配線器具を提供することを目的とする。
【0008】
【課題を解決するための手段】

【0009】
そして、この構成では、配線器具の組み立て工程において、筐体本体の側面の断面積が大きくなる部分の状態を測定することにより、筐体本体の向きが確認され、筐体本体への配線金具の組込作業が容易になり、特に、配線器具の組み立ての自動化が容易になり、製造コストが低減される。また、段部及び傾斜面は、筐体本体の断面積が変化する部分に設けることにより、デザインが簡略化されるとともに、成形が比較的容易になり、製造コストが低減される。
【0010】
なお、本発明において、配線器具とは、コンセント、スイッチ、及び端子台など、配線が接続される配線金具を筐体に収納した器具を広く含む意味である。
【0011】
【発明の実施の形態】
以下、本発明の前提となる配線器具の一実施の形態を図面を参照して説明する。
【0012】

【0013】
図1ないし図6において、11は配線器具で、この配線器具11は、サポートと呼ばれる取付枠に単数あるいは複数連設されたうえで壁面などの造営物に設置される連用配線器具である大角連用配線器具で、電源線に接続され、プラグPが電気的および機械的に着脱可能に接続されるコンセントを構成している。なお、以下、正面側を上側、底面側を下側として説明する。また、取付枠及び配線器具11の寸法は規格化されたもので、取付枠は、中間部に細長で長手方向に3個の器具取付手段を有する器具取付孔を備えている。そして、配線器具11は、取付枠の器具取付孔の任意の器具保持手段に取り付けられる1モジュールの大きさに形成され、すなわち、短方向の外形寸法は器具取付孔の長手方向の略1/3に形成されている。
【0014】
そして、この配線器具11は、筐体12と、この筐体12に収納される配線金具14となどを備えている。
【0015】
そして、筐体12は、筐体本体16と、カバー体17と、止め金具18となどを備えている。そして、筐体本体16及びカバー体17は、それぞれ絶縁性を有する白色あるいは乳白色などの合成樹脂にて一体に形成され、互いに組み合わせて止め金具18で連結固定された状態で、内側に配線金具14を収納する収納空間が構成されている。そして、筐体本体16は、図1ないし図7に示すように、上側を開口した略箱状をなし、内側には、仕切板部21を中心として、刃受け金具装着部22と、鎖状端子装着部23とが形成されている。さらに、各鎖状端子装着部23から下側に貫通して、図6に示すように、それぞれ一対の配線孔25が形成されているとともに、対をなす配線孔25同士の間に位置して、リリース孔26が形成されている。また、筐体本体16の底部31には、略平面状の底面部32の両端部から、下側に向かい突出部33が突設され、この突出部33に、配線孔25及びリリース孔26が形成されている。さらに、1カ所の配線孔25に隣接し、底面部32から下側に表示台部35が突設され、さらに、この表示台部35から下側に表示部36が突設されている。そして、この表示部36は、注意表示などを示すもので、本実施の形態では接地側極を示す「W」の文字が突設されている。さらに、この表示部36は、筐体本体16の他の部分とは異なる表面状態である異なる色彩に着色され、本実施の形態では、青色の塗料で印刷されている。また、底面部32には、種々の表示が突設あるいは凹設されて一体に形成されている。また、筐体本体16の両側の側部には、それぞれ上側の両端部に位置して、係合受部41が一体に形成されている。そして、この係合受部41には、上下に延びる案内溝部42と、この案内溝部42の下端部の両側に位置する係止段部43とが設けられている。
【0016】
また、この筐体本体16は、開口した上側が底部31側より面積が大きく、両側にそれぞれテーパ状の傾斜面44が形成されている。
【0017】
また、カバー体17は、平面略矩形状のカバー本体部46と、このカバー本体部46の両端の下端部から前後に延設されたフランジ部47とを備えている。そして、カバー本体部46の下側には、仕切板部51を中心として、一対の刃受け金具収納部52が形成され、この刃受け金具収納部52から上側に貫通して、一対のプラグ差込孔54が形成されている。さらに、カバー本体部46の上面には、各プラグ差込孔54を囲み、差込孔凹部55が曲面状に凹設されている。また、この差込孔凹部55の幅寸法は、図3に示すように、装着されるプラグPの幅寸法より大きく形成され、プラグPを装着した状態で、差込孔凹部55の一部が外部に露出するようになっている。また、各フランジ部47の両側部には、カバー側案内溝部57が形成されている。さらに、カバー本体部46の両端面には、フランジ部47から受け板部58が突設され、この受け板部58の両側部から両端方向に向かい、上下方向に延びるリブである係合突部59が突設されている。
【0018】
また、各止め金具18は、例えばステンレス板を打ち抜き屈曲などして、カバー体係合部61と、このカバー体係合部61の両側部から延設された筐体本体係合部62とが形成されている。そして、カバー体係合部61は、基板部64と、この基板部64の長手方向に沿った一端部から屈曲され直角に起立された係合片部65とを備えている。そして、係合片部65の略中央部には、矩形状の孔部66が形成されている。また、この孔部66に向かい、基板部64から切起部67が延設されている。さらに、係合片部65の反側に位置して、基板部64から取付爪部68が形成されている。また、筐体本体係合部62は、屈曲可能に幅狭に形成された屈曲部71と、この屈曲部71に続く腕部72と、この腕部72の先端部から略V字状に拡開して形成された係止部73とを備えている。
【0019】
一方、筐体12に収納される配線金具14は、例えば、スズ(Sn)入りの銅合金など導電性の良好な金属にて、筐体本体16の刃受け金具装着部22に装着される略U字状に屈曲された刃受部81と、この刃受部81から延設され、鎖状端子装着部23に装着される略L字状の鎖状接続部82とが形成されている。さらに、鎖状端子装着部23には、ステンレス製などの弾性を有する部材で形成された板ばねなどの付勢手段84が装着されるとともに、例えば、筐体本体16と同じ材質の合成樹脂などにて形成されたリリースボタン86が進退可能に収納されている。
【0020】
そして、この配線器具11の組み立ては、まず、筐体本体16の内側に、リリースボタン86、付勢手段84、及び配線金具14を装着し、筐体本体16の上側にカバー体17を被せる。この状態で、止め金具18の基板部64をカバー体17のフランジ部47上に位置させるとともに、カバー体17の係合突部59間に止め金具18の係合片部65を挿入して係合し、止め金具18を仮止めして横ずれを防止する。そして、この状態から、自動機により止め金具18の筐体本体係合部62に曲げの力を加え、屈曲部71などを屈曲し、腕部72をカバー側案内溝部57及び案内溝部42に嵌入するとともに、先端の係止部73を係止段部43の下側に係止する。この状態で、止め金具18により筐体本体16とカバー体17とが連結固定され、配線器具11が完成する。
【0021】
そして、この配線器具11は、図示しない取付枠などを用いて壁面などの造営物に設置された状態で、各配線孔25から電源線などの配線の芯線を挿入することにより、この芯線が配線金具14の鎖状接続部82と付勢手段84との間に挟持され電気的に接続されるとともに機械的に鎖状接続される。そして、プラグ差込孔54からプラグの刃を挿入することにより、この刃は刃受部81に挟持され、電気的に及び機械的に接続され、配線金具14を介して、プラグに接続された電気機器に電力を供給できる。また、配線器具11の交換などの際は、リリース孔26からドライバなどの治具を挿入することにより、付勢手段84を後退させ、配線を取り外しできるようになっている。
【0022】
そして、本実施の形態によれば、カバー体17に対をなす係合突部59を互いに離間して突設し、これら係合突部59内に止め金具18の係合片部65を係合することにより、止め金具18を仮止めできる。そして、止め金具のカバー体係合部の両側部から対をなす係合片部を突設しこれら係合片部間にカバー体の係合突部を係合する構成に比べ、係合する係合片部65と屈曲される筐体本体係合部62との距離が確保しやすくなるため、カバー体係合部61の両側部に設けた筐体本体係合部62を屈曲する際の力が係合片部65に加わりにくくなり、寸法のむらの発生を抑制し、組み立ての作業性を良好にできる。さらに、係合部分と止め金具18の屈曲部分との距離が離間すると同時に、係合突部59の機械的強度を容易に確保できる。
【0023】
また、本実施の形態では、配線器具11の底部31の表示部36を、底面部32から突出させ、加えて文字部分のみをさらに突出させ、かつ、本体色すなわち底面部32と異なる色彩で印刷して着色したため、注意などの表示を目立たせて分かりやすくでき、設置作業を容易にできる。
【0024】
また、表示部36は、底部31で最も突出して形成するのではなく、この表示部36を挟んで、一対の突出部33を表示部36よりも突設させたため、配線器具11の組み立て作業の際に表示部36が他の部材などに摺接して印刷した着色が剥がれることなどを防止でき、組み立ての作業性を良好にできる。
【0025】
さらに、この表示部36を突出部33に隣接させたため、さらに表示部36を他の部材に接触しにくくできる。
【0026】
また、文字部分を突出部33に近い高さまで突設させることにより、印刷が行いやすくなり、特に、転写による印刷を行いやすくできる。
【0027】
さらに、底面部32の一部分のみを突出部33に近い位置まで突出させることにより、底面部32の全体を突出させる構成に比べて、材料費を軽減できる。
【0028】
また、突出部33に配線孔25を設けたため、電線の挿入時に、この電線が文字部分に触れにくくなり、印刷を剥がれにくくできる。なお、突出部33に配線孔25が設けられていることは必須ではない
【0029】
また、表示部36は、必要に応じて、底面部32あるいは表示台部35よりも低くすなわち凹設し、この凹部の内側あるいは外側に着色することもできる。そして、凹部内に着色する構成では、こすれによる印刷塗料の剥がれを防止できる。
【0030】
また、図6に示すように、接地側極に位置する突出部33に設けた配線孔25の周囲の凹設部分25a についても、着色などして表面状態を他方と異ならせることにより、注意などの表示を目立たせて分かりやすくでき、設置作業を容易にできる。
【0031】
また、上記の実施の形態では、配線器具として、単相100Vの一般タイプのコンセントを説明したが、本発明は種々の配線器具に適用可能であり、例えば、コンセントとしては、単相100Vのほか、単相200V、三相200Vが可能であり、また、複数のプラグを装着できるいわゆるダブルコンセントの構成や、接地極付きの構成、あるいは、引掛形のタイプに適用することもできる。また、コンセントのほか、片切、両切、3路、4路、タイマー付きなどの種々のスイッチに適用することもできる。
【0032】
図8は本発明の前提となる筐体本体の他の実施の形態を示す底面図である。
【0033】
すなわち、この図8に示す配線器具11は、筐体12の内部にスイッチ機構を収納するとともに、図示しないカバー体に操作部として揺動可能なスイッチハンドルを設けた3路スイッチで、底部31には、一対の配線孔25に隣接して、それぞれ表示台部35が突設され、さらに、これら表示台部35に「1」及び「3」の表示が突出部33より低く突設されかつ着色され、表示部36が形成され、上記のコンセントである配線器具11と同様の効果を奏している。そして、この「1」及び「3」の表示は、例えば、階段の上下に配線器具11を設置する際に、同じ番号同士を結ぶように電気接続することにより、所用の配線を容易に行えるようになっている。
【0034】
また、例えば、上記の筐体12の筐体本体16などはほぼ幅方向に対称に形成されており、例えば、筐体本体16の両側面にはそれぞれ傾斜面44が形成されているが、この形状を非対称とすることにより、筐体12の筐体本体16の向きを容易に確認でき、機械による確認も容易になって、製造コストを低減できる。
【0035】
図9は本発明の配線器具の実施の形態を示す図3のI−I相当位置の断面の説明図である。
【0036】
すなわち、この図9に示す実施の形態では、例えば、壁面に埋め込まれて使用される配線器具などに関し、一面に開口を有し、この開口を有する一面が対向する底面部32より大きな面積を有する筐体本体(ケース体)16と、この筐体本体16の開口を覆うカバー体17と、これら筐体本体16とカバー体17とで構成される筐体12に収納される配線金具とを備えた配線器具について、筐体本体16の底面部32から一面にかけて断面積が大きくなる部分について、一側は傾斜面44とする一方、この傾斜面44に対向する他の側面は段状の段部91などとして、両側面の形状が互いに異なるように形成している。
【0037】
そこで、この構成では、配線器具11の組み立て工程において、筐体本体16の側面の断面積が大きくなる部分にこの側面と垂直にレーザ光線Lを照射し、このレーザ光線Lの反射光Rの有無をセンサで測定することなどにより、筐体本体16向きを確認できる。すなわち、段状に断面積が大きくなる段部91では、レーザ光線Lを入射方向に反射する一方、テーパ状の傾斜面44は、レーザ光線Lを入射方向に反射しないため、反射光線の有無で、筐体本体16の向きを識別できる。
【0038】
そして、配線器具11の組み立てを自動化した際には、筐体本体16を所定の向きに揃えることにより、端子などの配線金具を筐体本体16の内部の所定の位置に所定の向きで挿入でき、製造コストを低減できる。
【0039】
また、これら段部91や傾斜面44は、筐体本体16の断面積が変化する部分に設けることにより、デザインを簡略化できるとともに、樹脂による一体成形などの成形を比較的容易にでき、製造コストを低減できる。
【0040】
【発明の効果】
求項記載の配線器具によれば、配線金具を収納する筐体の筐体本体に、断面積が変化する部分の一側面に傾斜面を形成し他側面に段部を形成したため、配線器具の組み立て工程において、筐体本体の側面の断面積が大きくなる部分の状態を測定することにより、筐体本体の向きを確認でき、筐体本体への配線金具の組込作業を容易にでき、特に、配線器具の組み立ての自動化を容易にでき、製造コストを低減できる。また、段部及び傾斜面は、筐体本体の断面積が変化する部分に設けることにより、デザインを簡略化できるとともに、成形を比較的容易にでき、製造コストを低減できる。
