Connector for an audio cable, a combination connector and cable, and a method of securing said connector to said cable
First Claim
1. A connector for an audio cable which contains a plurality of wires each having an exposed terminal surface, comprising:
- a) a connector body formed from an electrically conductive material and having a longitudinal central axis, said connector body having a first end sized to abut an end of an audio cable, a second end shaped to be securely attached to a connecting post formed on a piece of audio equipment, and an exterior surface which extends between said first and second ends, said exterior surface having a first portion, a second portion and a third portion, said first portion having a circular outer periphery with a length measured parallel to said longitudinal central axis, said first portion being located adjacent to said first end, said first portion is sized to receive said exposed terminal surface of each of said wires, said second portion being relatively flat and located adjacent to said second end, and said third portion converges downward from said first portion to said second portion;
b) an insulating layer extending over at least the length of said first portion and surrounding said exposed terminal surface of each of said wires; and
c) a band surrounding said insulating layer and extending over said first portion, said band being formed from a pliable material which is capable of being reduced in circumference to provide a positive electrical interface between said exposed terminal surface of each of said wires and said first portion.

Abstract
A connector for an audio cable, a combination connector and cable, and a method of securing the connector to the cable are disclosed. The connector includes a connector body formed from an electrically conductive material and having a first end sized to abut an end of an audio speaker cable, a second end shaped to be securely attached to a connecting post formed on a piece of audio equipment, and an exterior surface located therebetween. The exterior surface has a first portion, a second portion and a third portion. The first portion is sized to receive the exposed terminal surface of each of a plurality of wires present in the cable. An insulating layer extends over the exposed terminal surface of each of said wires and a band surrounds the insulating layer to provide a positive electrical interface between the exposed terminal surfaces and the first portion.

10. A combination connector and audio cable comprising:
-
a) a connector body formed from an electrically conductive material and having a longitudinal central axis, said connector body having a first end sized to abut an end of an audio cable, a second end shaped to be securely attached to a connecting post formed on a piece of audio equipment, and an exterior surface which extends between said first and second ends, said exterior surface having a first portion, a second portion and a third portion, said first portion having a circular outer periphery with a length measured parallel to said longitudinal central axis, said first portion being located adjacent to said first end and having a plurality of cavities formed therein, each of said cavities is sized to receive an exposed terminal surface of a wire, said second portion being relatively flat and located adjacent to said second end, and said third portion converges downward from said first portion to said second portion; b) an audio cable having a flexible tubular core formed from a non-electrically conductive material, said core having a longitudinal central axis, a first end, and a circumferential surface spaced at a constant radius from said longitudinal central axis, a plurality of spaced apart metallic wires extending along and positioned outward of said circumferential surface, each of said wires having an exposed terminal surface which extends beyond said first end of said tubular core, each of said wires being positioned at an equal distance from said longitudinal central axis, and a cover layer surrounding at least a portion of said tubular core and said plurality of wires, and when said connector body is abutted against said first end of said cable said exposed terminal surface of each of said wires will contact said first portion; c) an insulating layer extending over at least the length of said first portion and surrounding said exposed terminal surface of each of said wires; and d) a band surrounding said insulating layer and extending over said first portion, said band being formed from a pliable material which is capable of being reduced in circumference to provide a positive electrical interface between said exposed terminal surfaces of each of said wires and said first portion. - View Dependent Claims (11, 12, 13, 14, 15)
