Description

【0001】
【発明の属する技術分野】
本発明は、電気機器の端子カバーに関する。
【0002】
【従来の技術】
従来、電気機器の端子部を閉塞する端子カバーは特開平5−234627号公報に開示されるように、端子カバー(35)の長手方向の両端の一側部に夫々回動軸(35a)を形成し、これらの回動軸(35a)を受ける軸受け部(34a)を端子部(34)の上部の一側部の両側に形成し、端子カバー(35)を開閉自在に端子部(34)に取り付けている。また、軸受け部(34a)の上部に端子カバー(35)を開放するように回動させるときに乗り越え可能で、且つ端子カバー(35)が端子部(34)を閉塞する方向に回動することを阻止する突条(34d)を形成し、端子部(34)への結線作業がしやすいように端子カバー(35)が開放状態で保持できるようになっている。
【0003】
【発明が解決しようとする課題】
電気機器を盤の内部に取り付けて使用する場合、電気機器の底面を盤の背板に固定するため、端子部(34)を前面に向けるように縦に起こした状態で取り付けられて使用されるが、この状態で端子カバー(35)の開閉を繰り返していると突条(34d)が擦り減って保持力が低下してしまい、端子カバー(35)が開放状態で保持できなくなり、端子部(34)への結線作業時に端子カバー(35)を開放しても自重に耐えられずに閉塞してしまうという欠点があった。また、電気機器の形状によっては電気機器の前面に表示スペースがとれず、端子部(34)の近くに端子部の接続先を表示できない場合があった。
【0004】
そこで上記問題点に鑑み、本発明の目的は、長年の使用においても端子部への結線作業時に端子カバーが端子部を閉塞することがなく、また、電気機器の形状に拘わらずに端子部の近傍で端子部の接続先の表示ができる電気機器の端子カバーを提供することである。
【0005】
【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に記載の発明によれば、電気機器の端子部を閉塞する端子カバーにおいて、電気機器の左右側面に嵌合溝を形成し、端子カバーの左右両端に延設した腕部を嵌合溝に嵌合させて端子カバーをスライド自在に取り付けたことを特徴とする。
【0006】
請求項2に記載の発明によれば、請求項1に記載の電気機器の端子カバーにおいて、端子カバーに端子部の接続先を表示する表示部を設けたことを特徴とする。
【0007】
【発明の実施の形態】
請求項1に記載の発明によれば、電気機器の端子部を閉塞する端子カバーにおいて、電気機器の左右側面に嵌合溝を形成し、端子カバーの左右両端に延設した腕部を嵌合溝に嵌合させて端子カバーをスライド自在に取り付けたことにより、長年の使用においても端子部への結線作業時に端子カバーが端子部を閉塞することがない。
【0008】
請求項2に記載の発明によれば、請求項1に記載の電気機器の端子カバーにおいて、端子カバーに端子部の接続先を表示する表示部を設けたことにより、電気機器の形状に拘わらずに端子部の近傍で端子部の接続先の表示ができる。
【0009】
【実施例】
本発明に係る電気機器の端子カバーの実施例を図1〜図6の添付図面に基づいて説明する。
【0010】
図1と図2に示すように電気機器1は、本体ケース2の前端に複数の端子部3が並設され、各端子部3は隔壁4によって仕切られている。
【0011】
電気機器1の端子部3の両側の左右側面には嵌合溝5が水平方向に形成され、端子部3を被覆する端子カバー6は左右両端に腕部7が短手方向に延設され、この腕部7が本体ケース2の嵌合溝5に嵌合されて端子カバー6がスライド可能に取り付けられている。
【0012】
図3の拡大図に示すように端子カバー6は腕部7の先端の内側に突起8が形成され、図4の拡大図に示すように本体ケース2の嵌合溝5には突起8と対向する凹部9が形成され、端子カバー6のスライド長さを制限している。また、図3に示すように腕部7の先端と反対側の端部には係合突起10が形成され、図4に示すように本体ケース2には係合突起10が係合する係合凹部11が形成されて端子カバー6の閉塞状態を保持するようになっている。
【0013】
電気機器1を盤(図示せず)等の内部に取り付ける場合は本体ケース2の底面を盤の背板に螺子等を用いて固定し、端子部3を前面に向けるように図1の状態から縦に起こした状態で取り付けられる。
【0014】
電気機器1の端子部3に結線する場合は、端子カバー6を下方向にスライドさせて端子部3を開放して行う。端子カバー6は自重によって垂れ下がった状態で腕部7の突起8が嵌合溝5の凹部9の端部に係止して保持されるので、従来例のように長年の使用によって保持手段が劣化したりすることがなく、結線作業時に端子カバー6が端子部3を閉塞することがない。
【0015】
また、端子カバー6の表面には端子部3の接続先を表示する表示部12が設けられており、接続先を確認しながら結線作業を行うことができ、誤結線を防止できる。この表示部12にはシール等が用いて形成することができる。
【0016】
結線作業が終了したら、端子カバー6を上方向にスライドさせて端子部3を閉塞する。また、例えば、図5に示すように本体ケース2の前端に固定片13を回動可能に設け、端子カバー6の閉塞時に固定片13を回動させて端子カバー6の先端に係止させることにより、端子カバー6を確実に閉塞することができる。
【0017】
尚、電気機器1を反転させて取り付けた場合等で電気機器1の設置時に端子部3が上側になる場合は、図6に示すように端子カバー6を引き出した点で回動可能に形成することにより、端子カバー6を上方向にスライドさせた後、手前に回動させて保持することができる。この場合、表示部12は端子カバー6の裏面に設けると良い。
【0018】
また、端子カバーの形状や閉塞状態を保持するための構造について限定はなく、本発明の趣旨を逸脱しない範囲で適宜変更可能である。
【0019】
【発明の効果】
以上説明したように、請求項1に記載の発明によれば、電気機器の端子部を閉塞する端子カバーにおいて、電気機器の左右側面に嵌合溝を形成し、端子カバーの左右両端に延設した腕部を嵌合溝に嵌合させて端子カバーをスライド自在に取り付けたことにより、長年の使用においても端子部への結線作業時に端子カバーが端子部を閉塞することがないという効果がある。
【0020】
請求項2に記載の発明によれば、請求項1に記載の電気機器の端子カバーにおいて、端子カバーに端子部の接続先を表示する表示部を設けたことにより、電気機器の形状に拘わらずに端子部の近傍で端子部の接続先の表示ができるという効果がある。
