Definitions

  • This invention relates to a power supply adapter for portable electric devices.
  • Portable electric devices such as entertainment and storage devices, phones or computers have a variety of electrical connectors with corresponding power and data cables so that it is necessary to carry a corresponding number of power supplies and data cables, particularly when travelling. It is often the case that only one device may be charged at a time from a single power supply socket, particularly if one is using an international socket adapter in a foreign country.
  • a portable power supply adapter comprises:
  • the power supply may be a mains power supply or a low voltage power supply from another device.
  • a data transfer connection may be also provided by the socket.
  • the sockets are selected from at least one of: large and small USB sockets; iPod (registered trade mark) sockets, MP3 sockets, digital camera sockets, mobile telephone sockets and hard disk drives.
  • a wireless module such as a Bluetooth or Wifi unit may be connected to the socket to allow the portable device to communicate with the portable computer, for example for data transfer.
  • the casing comprises a base and a detachable cover, the cover including one or more apertures defining sockets for portable devices; the base including one or more detachable or integral connectors mounted on mountings so that a device inserted into a socket may be connected via a detachable connector to the power supply, wireless transceiver or other device.
  • the connector may be detachable to allow an alternative connector to be used.
  • the connector may be integral with the adaptor.
  • the mounting includes a seat for the connector arranged to secure the connector in an appropriate orientation, for example, facing upwardly, for engagement with a device inserted into the socket.
  • a detachable connector for a portable device power supply comprises;
  • the connectors are preferably USB connectors.
  • the circuit comprises a printed circuit board.
  • the printed circuit board may carry components selected from a voltage divider, a circuit limiter, a voltage limiter and a smoothing circuit.
  • the voltage divider, circuit limiter or voltage limiter may be programmable to sense the model of the portable device and to set the voltage and/or current appropriately.
  • the printed circuit may include a current source to provide a constant current at various voltages.
  • the printed circuit comprises a printed circuit board extending perpendicular to the connectors within the housing.
  • the circuit may comprise a printed circuit board extending parallel between the connectors within the housing.
  • the detachable connector may comprise a housing and a device connector extending from the housing in a first direction and a power supply and/or data connector extending from the housing in a second direction.
  • the device connector is configured to connect to a device and the power supply and/or data connector is configured to connect to the power supply and/or to a data transmission circuit.
  • the first direction is opposite to the second direction.
  • the device connector and power connector are coaxial so that the housing extends linearly between the connectors.
  • the device connector and power connector are parallel, arranged side-by-side in a stacked or folded arrangement.
  • the length of the housing and consequently of the detachable connector are reduced. This permits reduction in the height of the adapter when mounted upright.
  • the stacked or folded arrangement of the housing may provide an abutment, for example a ledge or rebate for secure engagement with the casing.
  • the printed circuit board may be perpendicular to the connectors.
  • the casing includes an upwardly facing socket located at or adjacent an edge of the casing.
  • the socket may include locking means for receiving and securely engaging a portable device connected to the socket for charging.
  • the detachable connector may be engaged by the locking means.
  • the locking means may comprise a spring latch or a deformable resilient member dimensioned to provide a press fit engagement at the lower edge of a portable device.
  • a quick release button may be provided to release the latch or to open the deformable member.
  • the casing may be rectangular in plan view having longer and shorter sides, the socket being located at an upper edge of a shorter side.
  • a mobile phone or other device may be engaged with the control panel facing outwardly from the shorter edge so that the long sides of the casing extend rearwardly to provide a secure support resistant to toppling backwards when the key pad of the phone is actuated.
  • the upper surface of the casing may include a rebate adapted to abut and support the device or a detachable or an integral connector.
  • the rebate may comprise side and rear surfaces dimensioned to snugly fit the connector supporting the connector against movement as the portable device is used or as it is engaged or disengaged from the socket.
  • the stacked or folded configuration of the detachable connector may be arranged to provide a right angled shoulder or other downward facing seat portion adapted to form a close fit with a correspondingly shaped corner or other upwardly facing edge or shoulder portion of the casing and rebate.
  • the casing has a single socket.
  • the cover comprises inner and outer portions defining one or more channels between the portions for engagement with corresponding formations of the base.
  • the formations may comprise projections or flanges extending outwardly of the base.
  • the base may comprise runners extending transversely with respect to the sockets, the cover being arranged to be slidable on the runners between a closed position ready for use and an open position in which the connectors may be removed from the seats for replacement to accommodate different portable devices.
  • the cover and base may be hinged, having a locking member or clasp which may be released to open the device for replacement of the connectors.
  • An adapter in accordance with the present invention confers several advantages.
  • a single adapter may be used to power a lap-top or other portable computer and a range of portable devices, avoiding the need to carry a range of different power supplies.
  • the need for more than one mains adapter is avoided when travelling because only a single power supply is necessary.
  • the detachable connectors may be selected to suit the devices carried by the user.
  • a connector suitable for the user's mobile phone may be selected from the large number of connectors required to connect all commonly available phones.
  • the connector may include a circuit adapted to adjust or control the power supply to the mobile device.

  • a current source may provide a constant current at various voltages.
  • a filter may be provided to remove ripples from the voltage supply.
  • the PCB may be mounted perpendicularly of the connectors in the housing. This provides a shorter structure, particularly in a stacked housing arrangement.
  • the PCB may be mounted parallel to the connectors in the housing, for example between the connectors. This provides a slimmer structure.
  • the device connector is preferably configured to connect to the particular device for which the power supply is optimised.
  • the adapter may function as an electronic device docking station and may include a wireless communication module, arranged to transfer data between the portable device and a notebook or other portable computer connected to the power supply.
  • the wireless module may comprise a wireless transceiver connected to the circuit board of the adapter.
  • the connector may function as a bridge between the device and the wireless transceiver connected to the circuit board.
  • a kit may be provided comprising the casing and a selection of connectors.
  • An MP3 player (7) and mobile phone (8) are received in sockets within the upper casing of the adapter (1) and are engaged with detachable connectors (25) as shown in Figure 2 to enable charging directly whether or not lap-top (5) is connected to the portable computer power supply cable for simultaneous charging.
