TERMINAL BOARD AND AIR CIRCUIT BREAKER

PROBLEM TO BE SOLVED: To obtain a terminal board which allows for individual and convenient terminal connection work.SOLUTION: A terminal board 101 includes a current-carrying member 6 provided at the proximal part 3 of the terminal board, a terminal press member 5 for pushing a terminal 9 to be connected with this current-carrying member 6 to the current-carrying member 6 side and connecting therewith, and a cam 4 provided in the proximal part 3, rotating in one direction around a shaft 4a, and changing the pressing state of the terminal press member 5 to the current-carrying member 6 side according to the rotational state thereof, where one terminal press member 5 is disposed corresponding to one current-carrying member 6. The cam 4 controls the terminal press member 5 to become OFF state where it is separated from the current-carrying member 6 side in a first rotation range around the shaft 4a, and controls the current-carrying member 6 so that the terminal press member 5 is pushed to the current-carrying member 6 side to bring about ON state in a second rotation range.SELECTED DRAWING: Figure 6 【課題】端子接続作業を、個別に、かつ簡便に行うことができる端子台を得る。【解決手段】端子台１０１の基部３に設けられた通電部材６、この通電部材６に接続される端子９を、通電部材６側に押して接続させる端子押圧部材５、端子台３の内部に設けられ、軸部４ａ中心に一方向に回転し、その回転状態に応じて端子押圧部材５の通電部材６側への押圧状態を変化させるカム４を備え、一つの通電部材６に一つの端子押圧部材５が対応して配設されている。カム４は、軸部４ａを中心とした第一の回転範囲において、端子押圧部材５が通電部材６側から離間したＯＦＦ状態となるように端子押圧部材６を制御し、第二の回転範囲において、端子押圧部材５が通電部材６側に押されてＯＮ状態となるように端子押圧部材６を制御する。【選択図】図６
