Abstract: A protective cap protects a fusible link formed with a connection hole. A protective cap part is disposed on an extension of an axis of a stud bolt of a power source. The protective cap part is formed with a tool insertion hole into which a tool used for fitting a nut with the stud bolt is inserted. The stud bolt is inserted through the connection hole. A nut holder is provided inside the protective cap part. The nut holder holds the nut in a state where an axis of the nut is parallel to the axis of the stud bolt.

Abstract: A fusible link includes a fuse portion that has a first resistance portion and a second resistant portion which are formed of a fusible metal conductor. The first resistance portion has a fusible portion which is provided in proximity to a connecting portion of the first resistance portion with the second resistance portion and is adapted to be fused to be broken when the fusible portion is heated up by an overcurrent. The fusible link further includes a metal chip whose melting point is lower than a melting point of the fusible metal conductor, and which is adapted to be fused to be dispersed into the fusible portion for formation of an alloy phase when the metal chip is heated up by the overcurrent and a holding portion that is provided in proximity to the fusible portion for holding the metal chip. A ratio of resistance values of the first resistance portion and the second resistance portion is set so that a heat concentration portion of the fuse portion whose temperature is increased by the overcurrent in a rare-short-circuit range is shifted to a part of the first resistance portion which excepts the fusible portion.
