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.
Claims10
An excess current interrupting structure, comprising:
- a plurality of electrical conductors;
- an electrically conductive wire connected between at least a pair of the electric conductors;
- and
- a resin body between the pair of electrical conductors covering the electrically conductive wire and having a recessed portion formed on a side thereof that defines a thin layer of resin over the electrically conductive wire;
- the excess current interrupting structure being configured so that a current flow through the electrically conductive wire in excess of a predetermined level causes destruction of the thin resin layer over the electrically conductive wire and interruption of the electric current without regard to melting or destruction of the electrically conductive wire by the current flow in excess of a predetermined level.
