Description
また、該表示装置は飛び出しが悪くて該表示体が表示筒部の途中に引っ掛かったり、作業者が下方から見た場合に落下した表示体はその先端の小さな部分しか見えず溶断状態の確認がし難いという問題があった。
以下、本願発明のヒューズ溶断表示装置について、図1乃至図13に基づき説明する。
25hは連結紐穴、25iは表示部25eの底面に形成された水抜穴を示す。
なお、同蓋体25は下部カバー23の開口部23aに取脱自在に挿着して同開口部23aを閉鎖するもので、同部に挿着する蓋体25はその係止段部25cが係止用バネ26により係止された構成である。
かかる構成の表示装置において、過負荷や短絡により過大電流が流れるとヒューズ27が溶断する。ヒューズ27が溶断するとそれに伴って表示抵抗線が切れる。表示抵抗線が切断すると表示体31の抵抗線による拘束が解かれ、同表示体31が表示体収納筒30の表示穴30aから突出する。突出した表示体31は蓋体25の凹状の表示部25eに没入垂下する。

- カットアウトの下端開口部に取脱自在に挿着する透明の蓋体には、該蓋体の底面部の中央に位置してヒューズの溶断時、同ヒューズの溶断に伴ってカットアウトの下端に具える表示体が垂下没入する凹状の表示部を形成すると共に凹状の表示部を中心にして蓋体の周面方向に向かう適度の幅と表示部の深さと厚みを有する壁状の補助表示部を複数放射状に形成したことを特徴とする円筒形カットアウトのヒューズ溶断表示装置。
