Abstract

Abstract This invention relates to a phono plug and a method of making it. An insulated disc through which extends a center contact member terminated to a center conductor of a coaxial cable is positioned in the inside surface of a U-shaped outer shell member and enclosed therein by closing the shell member into a generally cylindrical housing. An open barrel integrally attached to the shell member is either simultaneously or subsequently crimped around the braided shield on the coaxial cable to complete the phono plug.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 178 words
A method of asembling a phono plug comprising the steps of: a. stripping a length of coaxial cable to expose the center conductor and the braided shield; b. providing a center contact member having a pin at one end and a wire barrel at another end and crimping the wire barrel around the exposed length of the center conductor; c. slipping an annular insulating disc around the pin on the center contact member; d. providing a shell member having an open housing portion at the forward end with a pair of fingers projecting rearwardly therefrom, and an open wire barrel at the rearward end and placing the disc carrying center contact member into the open housing portion so that the exposed braided shield lies in the open wire barrel; e. forming the open housing portion into a closed cylinder around the insulating disc with the fingers on the housing being placed into the open wire barrel; and f. crimping the wire barrel on the shell member into encompassing relation about the fingers and the braided shield lying therein.
Claim 2
Independent Claim 178 words
A method of asembling a phono plug comprising the steps of: a. stripping a length of coaxial cable to expose the center conductor and the braided shield; b. providing a center contact member having a pin at one end and a wire barrel at another end and crimping the wire barrel around the exposed length of the center conductor; c. slipping an annular insulating disc around the pin on the center contact member; d. providing a shell member having an open housing portion at the forward end with a pair of fingers projecting rearwardly therefrom, and an open wire barrel at the rearward end and placing the disc carrying center contact member into the open housing portion so that the exposed braided shield lies in the open wire barrel; e. forming the open housing portion into a closed cylinder around the insulating disc with the fingers on the housing being placed into the open wire barrel; and f. crimping the wire barrel on the shell member into encompassing relation about the fingers and the braided shield lying therein.
Claim 3
Dependent Claim 19 words
The method of claim 1 further including the step of placing a resilient retaining ring around the closed housing.
