Selectively engageable interface for circuit cards

An interface apparatus for establishing a first interface between an electronic unit and a circuit card, said electronic unit having a first base connector, said circuit card having a first card connector, said circuit card being insertable into said electronic unit so that said first base connector engages with said first card connector to form a second interface between said electronic unit and said circuit card, said interface apparatus comprising:

• an electronic unit;
• a second base connector attached to said electronic unit;
• a circuit card;
• a corresponding second card connector attached to said circuit card;
• and
• an actuator device for selectively engaging said second base connector with said second card connector to form said first interface between said electronic unit and said circuit card.

An interface apparatus for providing an RF interface between a circuit card and an electronic unit, said interface apparatus comprising:

• an electronic unit;
• a base connector connected to said electronic unit, said base connector having a substantially smooth engaging surface, said base connector comprising:
• a first base conductor, said first base conductor being recessed from said engaging surface of said base connector;
• a second base conductor, wherein said second base conductor comprises a convex, substantially hemispherical surface at said engaging surface of said base connector;
• and
• a base insulator, said base insulator insulating said first base conductor from said second base conductor;
• a circuit card;
• a card connector connected to said circuit card, wherein said card connector comprises a corresponding concave, substantially hemispherical surface at said engaging surface of said card connector, said card connector comprising:
• a first card conductor, said first card conductor protruding from said engaging surface of said card connector;
• a second card conductor, wherein said second card conductor comprises a plurality of conductor elements for establishing a substantially uniform electrical contact between said second card conductor and said second base conductor around substantially the entire circumference of said second base conductor;
• and
• a card insulator, said card insulator insulating said first card conductor from said second card conductor;
• and
• an actuator device for engaging said base conductor with said card connector so that said first base conductor makes electrical contact with said first card conductor and said second base conductor makes electrical contact with said second card conductor.
