In-line fuse holder for miniature plug-in fuse
First Claim
1. An in-line fuse holder for receiving a miniature, plug-in fuse having a fusible element coupled between a pair of juxtaposed, laterally spaced co-planar, parallel generally flat fuse terminals, said in-line fuse holder including in combination:
- a casing of insulative material having rigid wall surfaces, two clip assemblies mounted within said casing, each for engaging one of said flat fuse terminals of said plug-in fuse, each said clip assembly including first clip means of electrically conductive material, said first clip means being generally U shaped with legs of the U forming blades between which said flat fuse terminals are to be received, second clip means of resilient material, said second clip means being generally U shaped with the legs of the U forming blades and dimensioned for cooperating engagement with said first clip means in a tightly fitting overlying relationship with respect thereto, said second clip means including a tang extending outwardly from the surface of each of said blades of said second clip means for engagement with said rigid wall surfaces of said insulative casing, said tang and said rigid wall surfaces cooperating to increase the gripping force provided by said blades of said second clip means against the blades of said first clip means thereby to urge said blades of said first clip means into low electrical resistance contacting engagement with said fuse terminals and means extending from said first clip means for permanent external in-line electrical connection of said fuse holder.

Abstract
An in-line fuse holder capable of handling currents as high as 30 amps, adapted to accept miniature, relatively flat, plug-in fuses which have a pair of flat terminals and a fuse link visibly retained within a relatively flat plastic case. The in-line fuse holder has a relatively rigid casing in which a pair of generally U shaped contact clip assemblies are mounted for receiving the flat terminals of the plug-in fuse. The contact clips are of two piece construction with an inner clip of highly conductive material and an outer clip of highly resilient material. The outer clip fits over the inner clip to force the inner clip into low resistance contact with the fuse terminals.
