<P>PROBLEM TO BE SOLVED: To provide a fuse block which makes it possible to downsize a printed circuit board. <P>SOLUTION: A fuse block 1 comprises a plurality of bus bars 2, 3a to 3e, 4a to 4i and 5 which are bent in shape of the letter L. Each of the bus bars 2, 3a to 3e, 4a to 4i and 5 are provided at one end with at least one tuning-fork shaped connection part 6 which is connected to a fuse 9 and provided at the other end with at least one substrate connection part 7 which is soldered to a printed circuit board 13. The bus bars 2, 3a to 3e, 4a to 4i and 5 are arranged in parallel in the direction of the arrow X and also are laminated in four layers in the direction of the arrow Y. Furthermore, the substrate connection part 7 of the bus bar 4 in the third layer counted from the printed circuit board 13 side and the substrate connection part 7 of the bus bar 3 in the second layer are arranged on a straight line. In the second and the third layers, a total number of the substrate connection parts 7 is smaller than that of the tuning-fork shaped connection parts 6. <P>COPYRIGHT: (C)2013,JPO&INPIT |
