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 When the mold is opened, the core pins are withdrawn from the cavity, the core pins having formed the plug-receiving opening in the telephone jack.
