Solderless prong connector for coaxial cable
First Claim
1. A connector for mounting on the end of a coaxial shielded cable of the type having an inner conductor surrounded by an inner dialectric sleeve in turn surrounded by a tubular braided conductor in turn syrrounded by an outer dielectric sleeve, said connector comprising:
- an electrically conductive tubular body member having a first longitudinal bore accepting the coaxial cable, a second longitudinal bore of enlarged diameter and an end portion at the end of said second bore provided with an enlarged outer diameter and inner diameter portion;
a dielectric tubular plug having a longitudinal bore accepting the inner dielectric sleeve of said cable, said tubular plug being inserted in said second bore of said tubular body member with the tubular braided conductor and the outer dielectric sleeve of said cable compressibly secured between the peripheral surface of said plug and the inner surface of said second bore with an exposed end portion of said tubular braided conductor engaged with said inner surface of said second bore, said dielectric tubular plug having an enlarged outer diameter end portion disposed in the enlarged inner diameter portion of the end portion of said tubular body member and compressibly securing the exposed end portion of said tubular braided conductor between the enlarged outer diameter end portion of said tubular plug and the enlarged inner diameter portion at the end of said tubular body member;
an electrically conductive prong member partially inserted in the longitudinal bore of said dielectric tubular plug, an exposed end portion of said inner conductor being secured between a cylindrical portion of the peripheral surface of said prong and the inner surface of said bore in said tubular plug; and
an electrically conductive collar member having a rearwardly disposed inwardly extending shoulder portion for engagement with the enlarged outer diameter portion of said tubular body member, said collar member having an internal thread for engagement with the external thread of a receptacle for said prong member.

Abstract
A solderless prong connector for permanent mounting on the end of a coaxial shielded cable of the type having an inner conductor surrounded by an inner dielectric sleeve in turn surrounded by a tubular braided conductor in turn surrounded by an outer dielectric sleeve. The connector has an electrically conductive tubular body member passed over the coaxial cable, the body member being provided with an enlarged inner diameter portion on one end in which is press-fitted a dielectric tubular plug wedging the cable outer dielectric sleeve and tubular braided conductor between the peripheral surface of the plug and the inner surface of the enlarged diameter bore of the conductive body member, with the end portion of the tubular braided conductor engaged with a portion of such bore surface. The cable inner conductor, having its end exposed, and the inner dielectric sleeve covering the inner conductor are disposed in a longitudinal bore in the plug, and a prong is press-fitted in the tubular plug bore such as to wedge the exposed end of the inner conductor between the peripheral surface of the prong and the inner surface of the plug bore, thus providing secure mechanical and electrical connections and forming water-tight seals. A coaxially disposed threaded collar engaging a shoulder portion of the conductive tubular body member fastens the plug to an appropriate coaxial female receptacle and provides electrical continuity between the cable braided conductor and the female receptacle housing.
