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.

Abstract: A fusible link unit includes a housing and two fuse circuit bodies overlapped with each other and received in the housing in a thickness direction of the housing. A coupling plate and terminals connected to each other via fuse elements integrally forms the fuse circuit body. An opening is formed on an outer wall of the housing. The housing includes a cover made of transparent material and having a U-shaped section for covering the opening. The cover integrally includes a projection projecting to an inside of the housing on a sidewall of the cover. The projection includes a reflecting wall sloping on the sidewall in a thickness direction of the housing 7.

Abstract: A high-current fuse for vehicles is provided. This high-current fuse includes a conductive plate having a fuse and terminal connecting portions on both ends, and a resin case into which the conductive plate is insert-molded. A heat radiating portion for releasing heat generated from the fuse and the conductive plate when energized is provided on the outer surface of the resin case. The heat radiating portion is made up of a plurality of thin plates arranged on the resin case at regular intervals. The thin plates are situated in parallel with the energizing direction so as to strengthen the resin case. To keep the fuse away from both ends of the conductive plate, a pair of assisting plates facing to each other are formed in the middle of the conductive plate, and the fuse is disposed between the assisting plates. The fuse between the assisting plates is in the direction perpendicular to the energizing direction of the conductive plate.
