<p>PROBLEM TO BE SOLVED: To reduce size of a relay block and also lower thermal influence when a fusible link is provided to a bus bar. SOLUTION: A relay mounting area and a fuse mounting area are provided as the projected areas at the internal side from the circumferential wall of a block body, a bottom surface corresponding to gaps of relay mounting area and fuse mounting area is formed as a gap, a lower case to be coupled to lower part of the block body is formed in the shape that the bottom wall is engaged with a gap of block body, a bus bar is fixed to upper surface of the bottom wall and this bus bar allocated along the gap of the relay mounting area and fuse mounting area, a narrow fusible link (large capacity fuse) is provided in the course of bus bar, a tab to be inserted to terminal holes of the relay mounting area and fuse mounting area is bent and formed to one terminal of the bus bar, and a part which by-passes the relay mounting area and fuse mounting area is provided between the tab and fusible link. This by-passing area is formed in wide area as a heat radiating area.</p> |
