BLADE FUSE

摘要

Disclosed is a highly durable blade fuse for which a fused site in a narrow section and the rated current are determined in conformity with its design and the temperature of which does not increase greatly when a current flows through it. A blade fuse according to the present invention includes terminal sections (A, B) and a connection section (1), which are made of the same metal base material that is zinc or a zinc alloy. Furthermore, a low-melting-point metal piece (3), made of tin, which has an outer size identical or similar to a width of the connection section (1) is melted and stuck on at least one surface of the connection section (1) outside the fused section (2), and is positioned to partially traverse an edge of the fused section (2) or not to traverse the edge but to be adjacent to the edge.

主权项

1. A blade fuse comprising:
a pair of terminal sections positioned at both ends of the blade fuse; a connection section formed of a fusible metal body positioned between and connecting the terminal sections: a fused section formed in a central section of the connection section, the fused section being smaller in cross section than other portions of the connection section, and a low-melting-point metal piece having an outer size identical or similar to the width of the connection section, the low-melting-point metal piece is positioned on the connection section such that the low-melting-point metal piece partially traverses an edge of the fused section or is adjacent to an edge of the fused section but does not to traverse the edge of the fused section, wherein: the terminal sections and the connection section are made of the same metal base material that is zinc or a zinc alloy
