Abstract: Electrical fuse comprises an insulating body having a pair of coplanar blades extending from one end thereof. The blades have portions which are supported in the body and a fuse metal link is contained in the insulating body and extends between the supported portions. The conductors which comprise the blades and the supported portions of the blades are produced by die casting and the fuse metal link is insert die cast in these conductors. The insulating body is molded onto the conductors.

Abstract: A method of manufacturing an electrical connector of the telephone jack type by insert molding, is disclosed. The conductors for the connector jack are first stamped and formed in continuous strip form from conductive sheet metal with the continuous strip having groups of conductors extending therefrom and spaced along the length of the strip. The strip is fed to an injection molding apparatus and the leading set of conductors of the strip is clamped in the mold of the apparatus in a manner such that the contact portions of the conductors are held between core pins. These core pins extend into the mold cavity so that when the plastic material fills the mold, intermediate portions of the conductors will be embedded in the molding material. When the mold is opened, the core pins are withdrawn from the cavity, the core pins having formed the plug-receiving opening in the telephone jack.

Abstract: Electrical connector receptacle comprises an insulating housing having a plug-receiving end and a plug-receiving cavity extending into the plug-receiving end. A plurality of side-by-side stamped and formed conductors are insert-molded in the housing and have intermediate portions imbedded in the housing between one of the internal sidewalls of the opening and the adjacent external sidewall of the housing. First end portions of the conductors emerge from the one internal sidewall of the opening proximate to the plug-receiving end and extend diagonally from the internal sidewall into the cavity, these first end portions serving as spring contacts. The second ends of the conductors emerge from the adjacent external sidewall at a location adjacent to the rearward end of the housing. Stamped and formed metallic mounting posts are imbedded into the housing and extend from the adjacent external sidewall.
