Exchangeable multi-functional interface card for connection to a peripheral unit so that it can, in turn, be connected to any other device having an interface matching any of the plug in card interface options

摘要

An exchangeable multi-functional interface card (1) for connection of an electronic unit, comprises a peripheral unit (2) with a rotatable T-shaped connection socket (3) and a matching plug interface, which has a rotation-symmetric pin (11) with four contact surfaces (1101-1104) on one end so that after insertion of the pin in the socket data transfer between the two is possible.
