【発明の属する技術分野】
この発明は、幹線から分岐線に分岐する、分岐接続部の分岐用端子ユニットにおいて、内蔵するヒューズの交換が容易に行えるヒューズ内蔵分岐用端子ユニットに関するものである。
【0002】
【従来の技術】
従来、低圧分岐接続部は、図12に示すごとく、幹線接続体へ接続する端子(イ)と分岐用電線(ロ)との間に低圧限流ヒューズ(ハ)を設け、これらの分岐用電線(ロ)端にはキャップ形状からなるゴムカバー(ニ)を被せ、上記幹線接続体へ接続する端子(イ)に一端を固定したヒューズ筒(ホ)の他端を上記ゴムカバー(ニ)の一端に固定し、上記分岐用電線(ロ)端、低圧限流ヒューズ(ハ)及び幹線接続体へ接続する端子(イ)をこれらのゴムカバー(ニ)及びヒューズ筒(ホ)で被った構造を採っている。そして上記低圧限流ヒューズ(ハ)を取り替える際は、ヒューズ筒(ホ)の一端外周に取り付けられたホースバンド(ヘ)を緩め、ゴムカバー(ニ)の一端のホースバンド(ト)も緩め、ヒューズ筒(ホ)とゴムカバー(ニ)とを一緒に移動させ、上記低圧限流ヒューズ(ハ)の両端の端子を露出させ、ヒューズ取付ボルト(チ)を外して、当該低圧限流ヒューズ(ハ)の交換作業を行っている。
【0003】
【発明が解決しようとする課題】
しかしながら、長年の間に上記分岐用電線(ロ)の外周表面に異物が付着している場合が多く、上記限流ヒューズ(ハ)の交換作業時には、これらの電線に付着した異物(汚れ等)を除去し、ゴムカバー(ニ)の滑りを良くしなければならない。さらにこのゴムカバー(ニ)と分岐用電線(ロ)の固定箇所には防水の目的でテープ巻き処理を施されいる場合があり、この場合には、さらに作業に難を来している。
【0004】
この発明は、上記の問題点に鑑みて為されたもので、ヒューズの交換作業時の作業を簡素化できるヒューズ内蔵分岐用端子ユニットを提供することにより、上記課題を解決しようとするものである。
【0005】
【課題を解決するための手段】
請求項1項の発明は、分岐接続部における幹線接続体へ接続する端子と分岐用電線との間にヒューズを設け、これらの分岐用電線端には略キャップ形状からなるゴムカバーを被せて固定し、上記幹線接続体へ接続する端子に一端を固定したヒューズ筒の他端を上記ゴムカバーの開口端に固定し、上記分岐用電線端、ヒューズ及び幹線接続体へ接続する端子端をこれらのゴムカバー及びヒューズ筒で被ったヒューズ内蔵分岐用端子ユニットにおいて、上記ゴムカバーの小径部を電線に固定し、当該ゴムカバーの開口端部に筒状部を一体に設け、この筒状部内側に上記ヒューズ筒の他端が挿入自在な構成を有する、ヒューズ内蔵分岐用端子ユニットとした。
【0006】
このヒューズ内蔵分岐用端子ユニットは、ヒューズ交換時には、ヒューズ筒の固定を解き、ヒューズ筒をゴムカバーの筒状部内周に挿入して、ヒューズの一端の端子部を露出し、当該箇所のヒューズ取付ボルトを外し、さらにヒューズ筒をゴムカバーから引き外し、上記ヒューズの他端の端子部を露出し、同様に当該箇所のヒューズ取付ボルトを外して上記ヒューズを外す。そして新しいヒューズを上記と逆の手順で装着する。
【0007】
【実施の形態】
以下この発明の実施の形態例を図に基づいて説明する。
このヒューズ内蔵分岐用端子ユニットは、図1に示すように、幹線接続体へ接続する接続端子をプラグイン本体1とし、分岐用電線をリード線2とし、これらを低圧限流ヒューズ3で接続した構成で、上記リード線2の端部から上記プラグイン本体1にかけてゴムカバー4及びヒューズ筒5を設けて、これらでリード線2と上記低圧限流ヒューズ3との接続部、当該低圧限流ヒューズ3及び当該限流ヒューズ3とプラグイン本体1との接続部を被っている。
【0008】
上記プラグイン本体1は、図2乃至図4に示すように、台座状導体6の一側から、この台座状導体6に対して直角に伸びた板体6aを設け、この板体6aの一側から可動ロッド7を突出させ、この可動ロッド7の先端にはアークシュート8を設けたものである。また上記台座状導体6の他側には、この台座状導体6に対して直角にヒューズ取付導体9を設けている。このヒューズ取付導体9には二つのボルト挿通孔10、10を穿ち、これらのボルト挿通孔10の一面両側にボルト回転防止用の突堤11、11(図4を参照)を設けている。上記台座状導体6、板体6aの外周は絶縁ゴムでモールドされ、上記可動ロッド7を中心とした深い椀状の第1キャップ部12aと上記台座状導体6を中心に浅い椀状の第2キャップ部12bを形成したゴムモールド絶縁キャップ12を構成している。また上記可動ロッド7と反対側のゴムモールド絶縁キャップ12の外面から、引き抜き用取っ手13が突設されている。
【0009】
上記リード線2の先端は芯線をむき出し、圧縮端子14を接続している。この圧縮端子14の先端側は、上記ヒューズ取付導体9と同じ構造に成っている。さらに上記低圧限流ヒューズ3は図5に示すように、略円筒状のヒューズ本体3aの両側から、板状の端子3bが突出し、これらの各端子3bにはそれらの下辺に、二つの切り込み3cが夫々間隔を開けて設けられている。
【0010】
そしてこの低圧限流ヒューズ3の両側の端子3bの一方は上記圧縮端子14に、又他方は上記プラグイン本体1のヒューズ取付導体9に夫々取り付けられている。具体的には、ヒューズ取付導体9の二つの各ボルト挿通孔10に夫々ボルト15、15を通し、各ボルト15の頭体15aを二つの突堤11と11の間に入れる。これにより各ボルト15は頭体15aが二つの突堤11に当たり、回転を阻止される。そしてこれらのボルト15、15の他端部に上記低圧限流ヒューズ3の端子3bの各切り込み3cを入れて、当該端子3cをヒューズ取付導体9の一側に重ね、上記各ボルト15を断面溝型のヒューズ押え板16の各孔に通して、上記端子3cの上からヒューズ押え板16を装着し、各ボルト15の端部にナット17、17を螺着して締め付け、固定したものである。なお当該低圧限流ヒューズ3の一方の端子3bと上記圧縮端子14との接続、固定もこれと同様である。
【0011】
さらに上記ゴムカバー4は、図1に示すごとく、一端のラッパ状部4aの開口端部に筒状部4bを一体に設けた構成で、上記ラッパ状部4aの小径部をリード線2の外周に、シール材又は常温収縮チューブ等でリード線2の外周との間で防水性を備えた形で固定してある。また上記筒状部4bは一定の長さを有し、その内周にヒューズ筒5の一端が挿入できる長さを有している。そしてヒューズ筒5の一端を上記筒状部4bの先端内周に係止し、当該ヒューズ筒5の他端を上記プラグイン本体1のゴムモールド絶縁キャップ12の第2キャップ部12bの内周にはめ入れている。そしてこれらのヒューズ筒5との接続部のゴムカバー4の外周及び上記第2キャップ部12bの外周にホースバンド18を被せて締め付け、これらの接続を防水性を備えた形で強固にしている。
【0012】
次のこのヒューズ内蔵分岐用端子ユニットの、低圧限流ヒューズ3を取り替えるには、まず上記プラグイン本体1の第2キャップ部12b外周のホースバンド18を緩め、次にゴムカバー4の筒状部4bの先端部外周に取り付けてあるホースバンド18を緩める。そこで図6に示すごとく、ゴムカバー4の筒状部4b内周にヒューズ筒5の一端を挿入し、低圧限流ヒューズ3の、プラグイン本体1と接続している端子3bの部分を露出させる。そして当該箇所の二つのナット17、17を緩め、図7に示すごとく、上記リード線2を曲げてヒューズ3の一方の端子3bをプラグイン本体1のヒューズ取付導体9から外す。次に、図8に示すごとく、ヒューズ筒5の一端をゴムカバー4から引出て、ヒューズ筒5を取り除き、低圧限流ヒューズ3の、圧縮端子14と接続している端子3bの部分を露出させる。そして図9に示すごとく、上記と同様に低圧限流ヒューズ3の他方の端子3bの部分を圧縮端子14から取り外す。
【0013】
そこで当該低圧限流ヒューズ3を取り除き、新しい低圧限流ヒューズ3を装着する。これは上記と逆の手順で行い、まず、図8に示すごとく、圧縮端子14に一方の端子3bを接続固定し、図7に示すごとく、ヒューズ筒5の一端をゴムカバー4の筒状部4bに挿入し、図6に示すごとく、リード線2を真っ直ぐに曲げ戻し、低圧限流ヒューズ3の他方の端子3bをプラグイン本体1のヒューズ取付導体9に取り付け、ヒューズ筒5の一端をゴムカバー4の筒状部4bから引き出して当該ヒューズ筒5の他端を上記プラグイン本体1のゴムモールド絶縁キャップ12の第2キャップ部12bの内周にはめ入れている。そしてこれらのヒューズ筒5との接続部のゴムカバー4の外周及び上記第2キャップ部12bの外周にホースバンド18を被せて締め付け、これらの接続を、防水性を備えた形で行う。
【0014】
またこのヒューズ内蔵分岐用端子ユニットは、例えば、地下孔内で使用する。図10及び図11はその例を示し、電源側の幹線接続体Aの各相から母線Bを水平方向に導出し、これらの各母線Bに予め設けた各受け部(図示省略)に、この発明のヒューズ内蔵分岐用端子ユニットCの上記プラグイン本体1を挿入して接続して構成し、このヒューズ内蔵分岐用端子ユニットCから分岐線を導出するものであり、このヒューズ内蔵分岐用端子ユニットCを多数横に並べ設けたものである。なお、図中Dは上記母線Bを支持する架台であり、Eは上方のクリート架台である。
【0015】
なお、上記実施の形態例では、ヒューズを低圧限流ヒューズ3とし、また分岐用電線をリード線2としたが、これに限定されるものではない。また、幹線接続体へ接続する接続端子を、上記実施の形態例ではプラグ型の挿入式のプラグイン本体1としたが、これに限定されるものではなく、適宜形式の接続端子であればよい。また上記ゴムカバー4のラッパ状部4aの小径部をリード線2の外周に固定するに際して、当該箇所に常温収縮チューブを用いて防水処理を施す場合は、地下孔内でも熱を使わず安定した作業が行える。
【0016】
【発明の効果】
請求項1項の発明においては、ヒューズ筒をゴムカバーの筒状部の内部に挿入できるため、ヒューズの交換時には、ヒューズ筒のみをゴムカバー内に動かすだけで、ゴムカバー自体を分岐用電線に対してずらす必要が無い。そのためゴムカバーの分岐用電線に対する防水処理を確実に維持できる。しかもヒューズ筒のみの移動で良いため、ヒューズ交換時の作業工程が簡素化され、極めて容易かつ迅速に行える。
