Title (EN) CURRENT CUT-OFF DEVICE, AND WIRE HARNESS
(FR) DISPOSITIF DE COUPURE DE COURANT, ET FAISCEAU DE CÂBLES
(JA) 電流遮断装置及びワイヤハーネス
Abstract:
(EN) A flow path of current i1 is split into a plurality of flow paths by a splitting part (11). A first current cut-off circuit (12) including a fusible link is connected to one flow path (15). A second current cut-off circuit (13) including semiconductor switch circuits (13a, 13b) is connected to the other flow path (16). The resistance value of each circuit is adjusted such that the current i2 of flow path (15) and the current i3 of flow path (16) are at a fixed ratio. The cut-off current of the fusible link becomes smaller, and thus the electric wire diameters of an upstream electric wire (22) and a downstream electric wire (23) which need to match this current can be reduced. As a result of forming a parallel circuit in combination with the fusible link, an increase in the size of the external shape of the second current cut-off circuit (13) can be inhibited.
(FR) Selon l'invention, un trajet de passage de courant i1 est séparé en une pluralité de trajets de passage par une partie de séparation (11). Un premier circuit de coupure de courant (12) comprenant une liaison par fusible est relié à un trajet de passage (15). Un deuxième circuit de coupure de courant (13) comprenant des circuits de commutation à semiconducteur (13a, 13b) est relié à l'autre trajet de passage (16). La valeur de résistance de chaque circuit est ajustée de telle sorte que le courant i2 du trajet de passage (15) et le courant i3 du trajet de passage (16) présentent un rapport fixe. Le courant de coupure de la liaison par fusible devient plus petit et, par conséquent, les diamètres d'un fil électrique amont (22) et d'un fil électrique aval (23) qui doivent correspondre à ce courant peuvent être réduits. La formation d'un circuit parallèle en association avec la liaison par fusible permet d'éviter une augmentation de la taille de la forme externe du deuxième circuit de coupure de courant (13).
(JA) 分流部(11)で電流i1の流路を複数に分岐させ、一方の流路(15)にはヒュージブルリンクを含む第1の電流遮断回路(12)を接続し、他方の流路(16)には半導体スイッチ回路(13a、13b)を含む第2の電流遮断回路(13)を接続する。流路(15)の電流i2と流路(16)の電流i3とが一定の比率になるように、各回路の抵抗値を調整する。ヒュージブルリンクの遮断電流が小さくなるため、この電流と整合させる必要のある上流側電線(22)および下流側電線(23)の電線径を細径化できる。ヒュージブルリンクと組み合わせて並列回路を構成することにより、第2の電流遮断回路(13)における外形サイズの大型化も防止できる。
