Abstract

For providing a fuse block in which a printed circuit board can be miniaturized, the fuse block includes a plurality of busbars formed into an L-shape. Each of the busbars is provided at one end thereof with at least one tuning-fork shaped connecting portion to be connected with a fuse, and at the other end thereof with at least one board connecting portion to be connected with a printed circuit board by soldering. The busbars are arranged in parallel along a direction X and overlapped along a direction Y to form four layers. The board connecting portion of the busbar in a third layer numbered from the printed circuit board and the board connecting portion of the busbar in a second layer are arranged in one row on one straight line, so that total number of the rows is smaller than total number of the layers.

Dependent claims

A fuse block, comprising:

a plurality of busbars formed into an L-shape by bending only once a straight-band-shaped joint portion and provided at one end of each of the busbars with at least one tuning-fork shaped connecting portion connected to a fuse, and at the other end thereof with at least one board connecting portion connected to a printed circuit board by soldering;
wherein the plurality of busbars is arranged along a first direction (X) and arranged along a second direction (Y),
wherein the tuning-fork shaped connecting portions of the busbars are arranged in a plurality of layers in the second direction (Y), and the board connecting portions of the busbars are arranged in a plurality of rows separated from each other along a third direction (Z) perpendicular to both the first direction and the second direction, and
wherein a total number of the rows in which the board connecting portions are arranged is less than a total number of the layers in which the tuning-fork shaped connecting portions are arranged.
