US 6,604,962 B1 · Plug for connection to an RCA or phono type socket

Abstract

A plug for connection to an RCA or phono type socket wherein a signal pin (15) is frictionally located within the bore of said socket and a pin-like return conductor (16) is adapted to make contact with the socket casing. The spacing (17) between the signal pin and return conductor is by means of a non-conductive plastic polymer or similar material, such material also assisting to engage the return conductor against the outside casing of the RCA socket. By reducing the amount of conductive metal material used in the return conductor of a typical RCA plug i.e. by using a pin-like return conductor rather than a cylindrical conductive band and associated support body, the present invention reduces inductive, capacitive and eddy current distortion and offers improved signal transmission.

Dependent claims

A plug, having signal and return (or ground) male conductive pins, for connection to an RCA or phono socket;

wherein the return or ground conductor of pin-like construction is held in an operative spaced relationship to the signal pin by means of non-conductive material such as plastic polymer, and adapted to make electrical contact with the socket's external ground casing when the signal pin is located within the socket's internal signal bore, and when the plug's retaining means, such as a continuous side wall or a plurality of circumferentially spaced wall portions, of said non-conductive material engages the socket's external ground casing applying pressure to and forcing said return or ground conductor against the socket's external ground casing.
