Abstract
An excess current interrupting structure comprising a conductive wire rod which generates heat by an excess current connected between a pair of electric conductors, a circumference of the conductive wire rod being covered with a resin with a thin coated layer formed in the vicinity of a path of the conductive wire rod.
Claims12
A method for manufacturing an excess current interrupting structure, comprising:
- preparing a lead frame comprising a plurality of electrical conductors, wherein a pair of the electrical conductors is configured to face one another across a gap;
- wire bonding a first electrically conductive wire between the pair of the electric conductors;
- forming by resin molding a resin body between the pair of electrical conductors covering the first electrically conductive wire;
- and
- forming a recessed portion being formed on a side of the resin body to define a thin layer of resin over the first electrically conductive wire.
