Abstract
Abstract A coaxial connector is described which has an improved plug pin and shell construction wherein the conventional machined pins and shells are replaced with stamped and drawn members providing for simpler manufacture, improved electrical and spring retention characteristics, and improved and simplified wire connections. In particular, the plug pin is hollow and is fixedly mounted in the plug shell, and the conductor is attached to the pin by a front end crimping of the hollow pin after the conductor is slipped into the pin.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
119 words
In an improved plug for a coaxial connector wherein an electrical connection is made between a pin in the plug and a contact in a connector socket the improvement comprising: a hollow forwardly opening plug shell; a hollow forwardly opening insulator disposed and gripped within said plug shell; a pin within the hollow of said insulator and having a hollow interior and being firmly attached to said insulator at a rear wall of said insulator hollow opening which is intermediately disposed longitudinally between ends of said insulator, said pin hollow interior opening rearwardly from said insulator rear wall for receiving a conductor and said pin hollow interior extending to the forward end of said pin within the hollow insulator;
