  • Combined charger connector, charger cable decoration, and spurious emission common-mode filtering coil
    Patent number: 9991646
    Abstract: Methods and apparatus, including computer program products, are provided for a filtering coil. In some example embodiments, there may be provided an apparatus. The apparatus may include a connector mated to enable coupling to a user equipment; and an air-core inductive coil coupled to the connector, wherein the air-core inductive coil includes at least one coil configured to attenuate a radio frequency signal emanating from the user equipment and pass at least direct current power signal to the connector.

  • Connecting element with a spring tab
    Patent number: 9865939
    Abstract: A connecting element for galvanically connecting two electrically conductive surfaces, comprises: a body plate having a body plate upper surface defining a body plate top level; and a spring tab extending from the body plate and having a spring tab upper surface comprising an upper contact section above the body plate top level. The connecting element has a connecting element bottom level, and the spring tab has a spring tab lower surface comprising a lower contact section, the spring tab having a rest position in which, with no external force applied onto the upper contact section, the lower contact section lies above the connecting element bottom level, and is bendable, by applying external force onto the upper contact section, to a compressed position in which the lower contact section lies in or below the connecting element bottom level.
