Patent ID: 7540771

Claim:
A coaxial connector comprising: a cylindrical body containing a dielectric therein; a main body containing an air dielectric therein, being connected to the cylindrical body at a right angle to the cylindrical body; a terminal conductor surrounded with the dielectric; a central conductor surrounded with the air dielectric, being connected to the terminal conductor at a right angle to the terminal conductor, and being protruded from a front side of the main body; a metal ring formed in close adjacent to the front side of the main body; and at least one ground supporter formed on the main body, being configured to support the main body in a way that a protruded portion of the central conductor is placed on a board in parallel with a surface of the board when the connector is mounted to a board, and to provide ground planes to the connector, wherein the main body includes an inner wall defining an opening therein, a first portion of the opening being adjacent to the cylindrical body and a second portion of the opening configured to be adjacent to the board, wherein the first portion of the opening is wider than the second portion of the opening, and wherein a portion of the central conductor adjacent to the terminal conductor has a greater diameter than a portion of the central conductor adjacent to the front side of the main body.
