Physically independent connector for retractable and removeable extensions in thin-profile electronic devices

A selectively removable computer expansion card comprising:

• a selectively movable extension that is configured to move between an extended position and a retracted position;
• and
• spring-loaded extensible connectors that couple the extension to a computer system, wherein at least one of the connectors provides a bias toward a side of the extension and provides an electrical connection between the extension and the computer system.

A retractable and removable antenna comprising:

• a selectively movable extension that is configured to move between a retracted position interior to a computer device to an extended position exterior to said computer device;
• spring-loaded extensible connectors that couple the extension to the computer device, wherein each of the connectors is a wireless, cable-less, plug-less electrical connection between the extension and the computer device, wherein at least one of the connectors is selectively and slidably coupled to an electrically conductive surface on a side of the extension to provide an electrical connection between said extension and said computer device.
