Retractable and removable extensions with edge plated PCB's in thin-profile electronic devices

A computer expansion card comprising:

• a movable extension extendable from said card, said extension comprising;
• electrical circuitry;
• a PCB having an edge;
• and
• an electrically conductive surface bonded to said edge and coupled to the electrical circuitry wherein a component may be electrically edge connected to said device.

An electronic device comprising:

• a retractable and removable electrical extension;
• an aperture through which said extension may project;
• a track on which said extension may move from a retracted position interior to said electronic device to an extended position exterior to said electronic device;
• said extension comprising
• a PCB having electrical circuitry and at least one edge, at least one electrically conductive surface on said edge, said conductor being connected to said electrical circuitry.

A system for affording electrical contact between an extensible printed circuit board and a host device, said system comprising:

• an extensible printed circuit board having an upper surface, a lower surface and at least one edge;
• an electrically conductive surface formed on said at least one edge of the extensible printed circuit board;
• and
• a conductor formed in the host device to enable selective electrical contact with said conductive surface as the printed circuit board is extended and retracted from the host device.
