Low Insertion Force High Power RF Connector

Disclosed is a novel connection for repeatedly connecting and disconnecting RF power for use in various applications (i.e., inductive heating, RF sputtering, evaporation, etc.).

State of the art RF connectors typically have a pin that is inserted into a ring of finger stock to make electrical contact. This type of connector is essentially a friction fit device which is prone to wear and tolerance degradation.

Finger stock type connectors are also prone to RF radiation leakage, and are generally unavailable for high power applications, (>1000 watts).

In any of the applications mentioned above, where there is a need for repeated connect and disconnect of RF power, a low insertion force quick disconnect connector is desirable.

The disclosed connector is easily fabricated, eliminates the wear problem, is essentially immune from RF radiation problems, and is compatible with very high power levels.

In operation, (see Fig.) the removable section 1 is inserted into fixed section 2 until they are in intimate contact. Further force compresses the connector vertically causing the internally tapered portion of section 2 to press on the external taper of section 3. This causes section 3 to compress horizontally and clamp on the power transfer pins 4.

A ground return path is continuous through the body of the connector which eliminates any radiation leakage.

Power is coupled into and out of the connector using standard 50-ohm connect...
