Abstract

In an exemplary embodiment, a hand-held data terminal has external electrical contact pads which mate with resilient contacts of a docking receptacle for the interchange of data and the supply of charging current to the terminal. The terminal may be loaded into and removed from the docking receptacle in a single motion with one hand. Keyboard and display of the terminal are fully accessible while in the docking receptacle. The terminal may be fully sealed and be completely free of the conventional pin and socket type electrical connector fittings at its exterior. Electrostatic discharge protection is provided by circuit components connected to the surface contact pads so that the sensitive electronic circuitry of the terminal is protected from electrostatic discharge transients.
