Abstract: A docking connector unit for connecting portable personal computers to various peripheral input/output (I/O) devices such as keyboard, monitor, printer, modem and mouse, comprises, in a first mode, two docking unit assemblies, one of which connects to the I/O ports of a computer, and comprises matching I/O ports and one component of a two-component consolidated electrical connector; the other of which comprises the other component of a two-component consolidated electrical connector, and I/O ports which duplicate the I/O ports of the computer. In a second mode, the first docking unit assembly is in effect permanently installed in the computer, so that the I/O ports of the computer are consolidated as one component of a two-component consolidated electrical connector.
