Abstract

This two-piece fuse comprises a generally rectangular plastic, dielectric housing, and a one-piece wire conductor. The conductor is folded into generally W-shaped configuration, and its inverted, V-shaped center section is inserted into a central recess in the bottom of the housing in such manner that its two, spaced, V-shaped legs are bent around the grooved, rounded ends of a pair of rigid web sections which project from the underside of the housing. Opposite ends of the folded wire are secured in a pair of spaced openings in the housing so that the two V-shaped legs of the wire are supported in a common plane by two web sections of the housing. The diameter of the wire is greater than the depth of the groove in each web section so that portions of the wire legs project out of the grooves for engagement with contacts when the leg sections of the wire are inserted into a cooperating female receptacle.

Dependent claims

A plug-in type fuse, comprising

an electrically non-conductive housing having therein a recess,
a continuous, substantially cylindrical one-piece wire fuse element secured to said housing,
said wire element being bent intermediate its ends to form a central section thereof which extends into said recess and a pair of spaced leg sections which extend from said central section to the exterior of said housing for insertion into a matching female fuse receptacle,
a portion of said central section of said element in said recess being non-cylindrical and reduced in cross sectional area as compared to the remaining portion of said element, and
rigid support means projecting from said housing and having therein shallow grooves in which said spaced leg sections are seated to be supported thereby for insertion into said receptacle,
said leg sections having at least portions thereof projecting from said grooves to make electrical contact with contacts in said female receptacle, when said leg sections are inserted thereinto.
