Title: STACKABLE CONNECTOR AND DEVICE FOR WIRELESS TRANSMISSION OF POWER
Abstract:
The present invention relates to a stackable connector for wireless transmission of power between separate devices comprising such a connector of a system, in particular of a patient monitoring system, said separate devices comprising such a connector. The connector comprises a housing (301, 407) and a magnetic coupling unit (302) arranged within the housing (301, 407) for transmitting power to and/or receiving power from another device of the system having a counterpart connector by use of inductive coupling. Said magnetic coupling unit includes a flux concentrator (303, 401, 411, 432, 442), at least part of which having a U-shaped cross-section forming a recess (304, 402, 412, 422, 437, 447) between the legs of the U, a first coil (305, 417, 431) arranged within the recess of the flux concentrator, and a second coil (306, 427, 441) arranged outside of the recess in which the first coil (305, 417, 431) is arranged. The housing (301, 407) is arranged to allow stacking of connectors upon each other so that the first coil (305, 417, 431) of the connector (300, 400, 410, 430) and a second coil of another connector stacked upon the connector together form a transformer for inductive power transmission there between and/or the second coil (306, 427, 441) of the connector (300, 400, 410, 430) and a first coil (305a) of another connector (300a) stacked upon the connector (300, 400, 410, 430) together form a transformer for inductive power transmission there between.
