Abstract

The coaxial cable connector includes an inner conductor or "signal wire" connector in the form of a hollow needle, an outer conductor or "wire mesh" or "cable sheath" connector spaced radially from the signal wire connector, insulation spaced radially between the inner and outer conductor connectors, and an external protective sleeve spaced radially from the wire mesh or cable sheath connector. Both the inner conductor needle and the insulation have alignment lugs for ease of manufacture and assembly, and the external diameter of the needle shaped ends are tapered to facilitate a simple method for gripping and providing a seal against water, dirt and debris. The end of a cable is inserted into the coaxial cable connector, without stripping, with the cable signal wire being directed into the signal wire connector. As the coaxial cable is depressed into the protective sleeve, the needle-shaped inner conductor electrically contacts the coaxial cable signal wire. Also during the cable insertion into the protective sleeve, the wire mesh or cable sheath connector simultaneously contacts the wire mesh or cable sheath of the cable end thereby establishing electrical contact. To assist in crimping, alignment projection(s) or indentation(s) on said housing are used to properly locate a pair of jaws of a plier-like apparatus over the protective sleeve.

Claims

1. A coaxial cable connector, comprising:

a housing made from an electrically conductive material;

first and second hollow, cylindrical sleeves extending from first and second ends of said housing, said first and second sleeves each being constructed of a material which is deformable onto a coaxial cable;

an inner conductor connector which passes through said housing, said inner conductor connector having first and second ends, each of said first and second ends project from said housing at a point centrally positioned within one of said first and second hollow, cylindrical sleeves;

insulation positioned between said housing and said inner conductor connector for electrically isolating said inner conductor connector from said housing; and

first and second outer conductor connectors, each of said first and second outer conductor connectors projecting from said housing at a point positioned within one of said first and second hollow, cylindrical sleeves, between said inner conductor connector and said one of said first and second hollow, cylindrical sleeves.

2. The coaxial cable connector recited in claim 1 further comprising a clamping alignment means positioned in said housing between said first and second ends selected from the group consisting of projections and depressions.

3. The coaxial cable connector recited in claim 1 wherein said first and second outer conductor connectors each comprise at least one point projection projecting from said housing.

4. The coaxial cable connector recited in claim 1 wherein said first and second outer conductor connectors each comprise a hollow sleeve which encircles said inner conductor connector.

5. The coaxial cable connector recited in claim 1 wherein said first and second ends of said inner conductor connector are hollow.

6. The coaxial cable connector recited in claim 5 wherein said inner conductor connector includes a solid central portion between said first and second ends.
