ABSTRACT:
An electromagnetic coupling connector for transferring data by an electromagnetic coupling system, including a plurality of data transfer coils for transferring data, disposed at an end portion of a side surface of the connector, a waveform shaper for shaping a waveform of a data signal received by the data transfer coils, and a connector for transferring the signal obtained by the waveform shaper to an equipment to which the electromagnetic coupling connector is fitted. The electromagnetic coupling connector may include a signal transmission/reception portion and a power transmission or reception portion, the signal transmission/reception portion includes a signal amplification circuit, a waveform shaping circuit, a serial/parallel signal conversion circuit and a parallel/serial signal conversion circuit, the power transmission portion includes an oscillation circuit, and the power reception portion includes a rectification/smoothing circuit and a constant voltage.
