Patent ID: 7612647

Claim:
A fusible link ( 1 ) comprising: a connection plate ( 2 ), a fusible portion ( 3 ) continuous with one side of the connection plate ( 2 ), a terminal ( 4 ) continuous with the fusible portion ( 3 ), at least one ruse element ( 5 ) having the fusible portion ( 3 ) and the terminal ( 4 ), a fuse circuit ( 6 ) having the connection plate ( 2 ) continuous with the fuse element ( 5 ), and a housing ( 7 ) accommodating the fuse circuit ( 6 ), wherein a plurality of the fuse circuits ( 6 ), including upper fuse circuits ( 61 ) and lower fuse circuits ( 62 ), are layered with a space therebetween in the housing ( 7 ), the fusible portion ( 3 ) of one of the layered fuse circuits ( 6 ) being offset from the fusible portion ( 3 ) of an other of the plurality of the fuse circuits ( 6 ) which is disposed adjacent the one of the layered fuse circuits ( 6 ), said offset being perpendicular to a direction in which the fuse circuits ( 6 ) are layered and along a direction directed outwardly from the one side of the connection plate from which the fusible portion ( 3 ) is continuous, the fusible portion ( 3 ) including upper fusible portions ( 31 ) of the upper fuse circuit ( 61 ) and lower fusible portions ( 32 ) of the lower fuse circuit ( 62 ), and wherein both the fusible portions ( 31 ) of upper fuse circuits ( 61 ) and the fusible portions ( 32 ) of lower fuse circuits ( 62 ) received in the housing ( 7 ) are covered with a transparent cover ( 8 ) so as to permit detection of the upper fusible portions ( 31 ) and the lower fusible portions ( 32 ) from the outside of the housing ( 7 ), respectively, and wherein the upper fuse circuit ( 61 ) has the connection plate ( 21 ) formed with a U-shaped portion ( 21 b ) positioned horizontally and the lower fuse circuit ( 6 ) has the connection plate ( 22 ) formed with a U-shaped portion ( 22 b ) bent from the lower fuse circuit ( 62 ) to rise vertically.
