20100315192 | FUSIBLE LINK - 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. | 12-16-2010 |
20120309239 | PROTECTIVE CAP FOR PREVENTION OF OBLIQUE TIGHTENING OF FUSIBLE LINK DIRECTLY MOUNTED ON BATTERY - 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. | 12-06-2012 |
20130102205 | FUSE UNIT, MOLD STRUCTURE, AND MOLDING METHOD USING MOLD STRUCTURE - A mold structure includes a fixed mold and a movable mold to bury a bus bar having a main body circuit unit with a tuning-fork terminal along with molding of a resin molded product. The fixed mold and the movable mold being joined together are configured to nip a terminal base of the tuning-fork terminal between a terminal base receiving portion of the fixed mold and a terminal base abut portion of the movable mold in a state where the tuning-fork terminal is protruded outside a cavity which is formed by mold main body portions of the fixed mold and the movable mold being joined together and into which resin is injected. | 04-25-2013 |
20130181806 | FUSE UNIT - A fuse unit includes: a bus bar including a plurality of fusible parts interposed between a power supply side terminal and a plurality of load side terminals; and an insulating resin portion formed by insert molding using the bus bar as an insert component. The insulating resin portion includes: first and second resin portions respectively arranged at peripheries on the sides of the power supply side terminal and the load side terminals with respect to the fusible parts; and a plurality of coupling portions coupling the first resin portion and the second resin portion in a position outside each of the fusible parts. Each of the coupling portions is formed such that a reinforcement portion having a lower heat shrinkage rate than the insulating resin portion and having a higher strength than the insulating resin portion is an insert component. The reinforcement portion is provided using the bus bar. | 07-18-2013 |

20140070454 | DIE FOR INSERT MOLDING AND METHOD FOR INSERT MOLDING OF COLLAR - An insert-molding mold includes a pair of dies that molds a resin product having a collar insert-molded on an inner circumferential surface of a bolt insertion hole therein, and a bush that is adapted to be inserted in the collar. One die of the dies is provided with a bush insertion hole in which the bush is slidably inserted, and the other die is provided with a cavity surrounding the collar. The bush comprises an upper portion having a cross-sectional shape corresponding to an internal cross-sectional shape of the collar, and a lower portion having a cross-sectional shape corresponding to an external cross-sectional shape of the collar, and is elastically urged toward the other die. | 03-13-2014 |
20140090872 | ARRANGEMENT CONFIGURATION OF BUS BARS - In an arrangement configuration of bus bars including a plurality of bus bars having a connecting portion provided at a center portion thereof and a housing integrally molded while exposing the connecting portions of the plurality of bus bars, the bus bar has a pair of bending portions that is bent so that both edge sides come close to each other, the plurality of bus bars is arranged in parallel to each other so that the pair of bending portions is located adjacent to each other, and the housing is integrally molded so as to cover the pair of bending portions of each of the plurality of bus bars. | 04-03-2014 |
20140094062 | CONNECTION STRUCTURE OF BATTERY TERMINAL - In a connection structure of a battery terminal, including a battery terminal to be connected to a battery and a fuse unit to be mounted to the battery terminal through a fixing section, the connection structure being provided between the battery terminal and the fuse unit, the battery terminal is provided with a regulating protrusion formed in a protruding manner, while the fuse unit is provided with a plurality of regulating grooves, into one of which the regulating protrusion is made to engage so as to position a mounting position of the battery terminal to the fuse unit. | 04-03-2014 |
