Abstract

This specification discloses a terminal and a pigtail wire combination for holding small fuses, made up of a single piece of wire. The wire may be considered as having a first part and a second part integrally connected to the first part. The first part is wound to form a tightly wound hollow cylindrical coil having a plurality of turns disposed in engagement with each other. The second straight part of the wire is tangent to the last turn on one end of the coil and extends across the coil parallel to the diameter of the coil and terminates at a substantial distance from the coil. A pigtail wire can be soldered to the terminal and a fuse can be inserted in the coil. A pair of these terminals can be spaced from each other and both soldered to pigtail wires to support both ends of a suitable fuse. In the case of the fuse, the internal diameter of the cylinder formed by the wire is slightly smaller than the external diameter of the fuse terminals.

Dependent claims

A fuse and pigtail wire combination comprising,

a hollow cylindrical fuse body made of non-conducting material having a hollow cylindrical cuplike terminal made of conducting material and disposed on each end of said cylindrical body,
said terminal and pigtail being made of a single wire wound into a spiral,
each said pigtail wire having a first part and a second part integrally connected to said first part,
said first part being wound to form a tight coil on said cuplike terminal made of conductive material comprising a plurality of turns of slightly smaller internal diameter than the outside diameter of said cuplike terminals whereby said coil will grip the caps and make electrical contact with said caps disposed in the form of a hollow cylinder receiving a said cuplike terminal,
said second part comprising a straight section of wire disposed parallel to a diameter of said coil and extending diametrically across one end of said coil and terminating a substantial distance from said coil,
each said cuplike terminal member receiving an end of said hollow body,
said second part of each said pigtail wire being soldered to a straight pigtail wire.
