  • Patent number: 4164726
    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.

  • Patent number: 4128291
    Abstract: Fuse adapter terminals are provided for fuse holders of the type having a pair of spaced-apart spring clips which receive the ends of a cylindrical fuse. The basic adapter terminal comprises a substantially U-shaped member of electrically-conductive, resilient material which has two legs which are joined by an outwardly-curved central portion. Each leg has a first outwardly-curved lobe which is adjacent the central portion and which cooperates therewith to form an arcuate surface which is disposed in one of the fuse holder spring clips. Each leg also has a second outwardly-curved lobe which is adjacent the free end of the leg. The second lobes are oppositely disposed and cooperate with each other to receive one end of the fuse therebetween so that when a pair of the basic adapter terminals are utilized, each end of the fuse is mechanically supported by and electrically connected to the spring clip associated therewith.

  • Patent number: 4052689
    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.
