  • Patent number: 7967627
    Abstract: A two-part inductive connector comprises a primary part having a primary half core and a secondary part having a secondary half core, the primary part including first locking means which are engageable with second locking means on the secondary part, one of the primary or secondary parts further comprising a pin which is receivable in a recess formed in the other of the primary or secondary parts, the connector having an unlocked position in which the primary and secondary half cores are not aligned and in which the first and second locking means are not engaged, and a locked position in which the primary and secondary half cores are aligned and the first and second locking means engaged, the connector moving between the unlocked and locked positions by relative rotation of the primary and secondary parts about the pin.

  • Patent number: 7646279
    Abstract: Apparatus for supplying energy to a load, comprises a power supply unit (102) e.g. a switched mode electronic transformer or electronic ballast having an input for receiving current at mains frequency and a means for stepping-up said mains frequency to a higher frequency e.g. 30-50 kHz and an output for delivering energy at the higher frequency. A two part connector (108) has a first core portion (106) that has a primary winding (104) connected to the output of the power supply unit and a mating second core portion (112) that has a secondary winding (110) for delivery of energy to a load (114), the core portions being of a high resistivity material, e.g. a ferrite having a resistivity of at least 104 ?cm. The apparatus may be used to power e.g. low voltage halogen or other incandescent lighting, fluorescent lighting, or an electric motor, a power supply for a computer, radio, television or like electronic device, a heater or the like.
