摘要： The present application invention provides a fuse capable of saving space inside a casing even when the casing includes a plurality of fusion parts arranged side by side. A fuse includes: a fuse element including a fusion part provided between a pair of terminal portions; and a casing configured to house a part of the fuse element while causing the terminal portions to protrude outward. Two or more of the fusion parts are arranged in a lateral direction X orthogonal to a terminal portion direction Y connecting the terminal portions and connected to the terminal portions. The casing includes two casing split pieces configured to house the fuse element to sandwich the fuse element. The respective casing split pieces are fixed to each other by a frame-shaped fixing member configured to make one round of a periphery of the respective casing split pieces. A housing space N1 of the casing has a maximum width L1 in the vertical direction Z narrower than a maximum width L2 in the lateral direction X.

摘要： A multiple fuse device for a vehicle includes a circuit board with a battery-side bus bar portion and an alternator-side bus bar portion connected together by a temporary joint portion at a position apart from a fusing portion that provides charging current protection. An insulator housing is placed over the circuit board but the temporary joint portion is left uncovered by the insulator housing. A temporary joint portion is then at least partially removed. This partial removal may leave behind two temporary joint portion remnants, one on the battery-side bus bar portion, and one on the alternator-side bus bar portion. The temporary joint portion thus enhances the strength of the circuit board while the fuse device is being manufactured, which prevents the fusing portion from being accidentally deformed or broken during the device's assembly.
摘要翻译： 一种用于车辆的多重保险丝装置包括具有电池侧汇流条部分的电路板和通过临时接合部分在远离提供充电电流保护的熔断部分的位置处连接在一起的交流发电机侧汇流条部分。 绝缘体外壳放置在电路板上，但临时接合部分被绝缘体外壳覆盖。 然后至少部分地移除临时关节部分。 这种部分去除可能留下两个临时接头部分残余物，一个在电池侧汇流条部分上，一个在交流发电机侧汇流条部分上。 因此，在制造保险丝装置的同时，临时接合部分增强了电路板的强度，这防止了在装置组装期间熔合部分意外变形或断裂。

摘要： The present invention provides a fuse manufacturing method and a fuse that facilitate an assembling work of the fuse. Disclosed is a method of manufacturing a fuse including a fuse element including a pair of terminal portions and a fusing portion between the terminal portions, a casing for accommodating the fuse element, and a cap for closing openings at both ends of the casing. In this fuse manufacturing method, the fuse element is positioned in the casing such that the terminal portion of the fuse element protrudes from the opening of the casing, and a holding plate for holding the fuse element is inserted between a peripheral portion of the opening of the casing and an abutment piece provided at the terminal portion of the fuse element. Further, in this method, the opening of the casing is closed by the cap so as to cover the holding plate.
