Abstract
Abstract There is disclosed in the present application, a coaxial connector for microwave applications including an external conductive shell, a central conductor and an insulator of polytetrafluoroethylene (Teflon) or other non-conductive synthetic resin, interposed between the shell and the central conductor. The interior of the shell and the exterior of the central conductor are both roughened to provide an improved bond for a coat of epoxy resin adhesive which secures the shell and conductor to the insulator. For providing a superior anchor to the insulator, it is acid etched to roughen its epoxy contacting surfaces.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
75 words
A coaxial connector for microwave applications comprising an outer conductive shell having an internally roughened surface, an externally roughened inner conductor, a tubular insulator of synthetic resin interposed between the shell and the inner conductor, a layer of adhesive resin cement between the insulator and the shell and another layer of adhesive resin cement between the inner conductor and the insulator, the layers of adhesive cement being the sole bonds between their respective adjacent parts.
Claim 2
Dependent Claim
75 words
A coaxial connector for microwave applications comprising an outer conductive shell having an internally roughened surface, an externally roughened inner conductor, a tubular insulator of synthetic resin interposed between the shell and the inner conductor, a layer of adhesive resin cement between the insulator and the shell and another layer of adhesive resin cement between the inner conductor and the insulator, the layers of adhesive cement being the sole bonds between their respective adjacent parts.
Claim 3
Dependent Claim
28 words
A coaxial connector according to claim 1 further characterized in that the roughened surface of the shell comprises a shallow thread-like pattern on the interior of the shell.
Claim 4
Dependent Claim
32 words
A coaxial connector according to claim 1 further characterized in that the inner conductor is roughened by a shallow thread-like pattern produced by rolling without removing any material from the inner conductor.
Claim 5
Dependent Claim
21 words
A coaxial connector according to claim 3 further characterized in that the shell is internally roughened by a shallow thread-like pattern.
Claim 6
Dependent Claim
29 words
A coaxial connector according to claim 1 further characterized in that the insulator is of polytetrafluoroethylene and is etched to provide an improved anchor for the layers of cement.
Claim 7
Dependent Claim
17 words
A coaxial connector according to claim 5 further characterized in that the cement is an epoxy resin.
Claim 8
Dependent Claim
25 words
A coaxial connector according to claim 6 further characterized in that both the outer shell and the inner conductor are internally roughened by thread-like patterns.
