A subminiature coaxial connector (SMA) includes a shell, dielectric and conductor element that includes a biasing element that engages an interface contact tip and biases the interface contact tip into electrical contact against an electrical circuit, such as a trace on the circuit board without soldering, and adjusts for relative movements created by thermal mismatch.

DETAILED DESCRIPTION It is therefore an object of the present invention to provide a subminiature coaxial connector that overcomes the drawbacks of the prior art subminiature coaxial connectors as described above.
It is yet another object of the present invention to provide a subminiature coaxial connector that does not require soldering of the conductor against a circuit board trace or other circuit element and can adjust for relative movements created by thermal mismatch.
The present invention is advantageous and provides a novel and unobvious subminiature coaxial connector and a method of transferring a high frequeny signal in the Gigahertz (GHz) range using the subminiature coaxial connector standard.
The present invention allows a low cost and reliable subminiature coaxial connector interface that is aligned normal to the surface of a circuit board and any electrical traces thereon without using a traditional solder processing or through-hole mounts.
Thus, the subminiature coaxial connector of the present invention can be attached without subjecting the connector and circuit board to elevated temperatures required for soldering.
The subminiature coaxial connector of the present invention can also be attached to a circuit board without having access to the electrical traces during assembly or processing.
The subminiature coaxial connector can be mounted in an inexpensive manner and account for tolerance stack-up, thus allowing a housing (shell) that is less expensive than normal subminiature coaxial connectors because precision machining processes are not required as often required when manufacturing common subminiature coaxial connectors.
The subminiature coaxial connector of the present invention can automatically adjust to relative movements created by thermal mismatch of materials, thus allowing the use of less expensive materials, while decreasing the likelihood of signal degradation because of solder breaks and substrate cracking.
It can be used above 3 GHz even when there is a thermal mismatch
