ABSTRACT:
The invention discloses a non-contact way to provide electrical power and two-way digital communications between a host computer and its peripheral modules, such as IC memory cards, modems, and A/D converters. A special magnetic core is employed to provide efficient transfer of both large amounts of electrical power and high speed digital communications through transformer action. Peripheral modules requiring different power supply voltages or different data voltage levels can be accommodated and intermixed with modules of other types in the same host system. The mechanical design of the connector includes detent structure to align the assembly in three dimensions, both upon mating, and under mechanical environmental stress conditions during operation. The magnetic core has both power supply and data windings; the data winding has sections of opposite polarity so that the power supply signal imposed on the data winding cancels itself.
