Abstract: An encapsulated plug-in electrically conducting component is provided for mounting in an electrical connector. In one embodiment an elongate conducting element is transversely disposed across two spaced-apart generally parallel terminal posts and is secured at each of its ends to near the end of each post. In the preferred embodiment of the present invention, the component functions as a fuse wherein the elongate conducting element is a generally cylindrical fuse wire and wherein a solid unitary body of electrically insulating material encapsulates the fuse wire and the ends of each of the blades that are connected to the fuse wire. In another embodiment, a center portion of fuse wire is encapsulated with a thermoplastic to form a cylindrical body. The projecting end of the wire are bent over against the ends of the body. Cylindrical end caps compressively engage the body and are maintained in electrical contact with the fuse wire by solder material within the end caps.

Abstract: A cartridge type fuse having a casing. A pair of terminal plugs is press-fitted into the ends of said casing and conductively interconnected by a fusible element. Each of said pair of terminal plugs has a knurled lateral wall. A pair of annular fasteners is mounted on said casing each adjacent one of the ends thereof. Said fasteners press the wall of said casing radially inwardly into firm engagement with said knurled lateral walls of said pair of terminal plugs. The casing preferably includes an outermost ply of woven glass cloth, an innermost ply of woven glass cloth, and at least one intermediate ply of relatively loose non-woven fibers sandwiched between said outermost ply and said innermost ply, and the constituent plies of said casing are preferably integrated by polyester resin.

Abstract: Capacitor fuses differ from fuses intended for other purposes by the nature of their terminal elements. Their terminal elements must be adapted to be gripped by wrenches and hence be hexagonal in cross-section. Disclosed is a capacitor fuse having hexagonal elements press-fitted upon the ferrules of a fuse, the length of ferrule-receiving cavities in said hexagonal elements being substantially equal to the length of the ferrules of the fuse. One of the hexagonal elements is provided with an internally screw-threaded bore and the other of said hexagonal elements is provided with an externally screw-threaded projection extending in a direction away from said casing of the fuse.

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.
