  • this is done by replacing a removable component of a plug or socket with an insert, which contains the power management devices required for the above features.
  • the component replaced is a fuse, such as a cartridge fuse.
  • the replacement insert contains all the technology (radio chip, control, measurement) built into a housing, which may be made to look like a fuse, so that a user can simply replace the existing fuse with the insert.
  • the features previously requiring an unwieldy plug-in device can therefore be completely hidden inside the plug or socket.
  • control and/or metering functions with the use of an overcurrent device to replace a fuse, allows the miniaturisation of the power management device into the plug, without compromising the overcurrent protection.
  • FIG. 2 illustrates a similar plug, however here the cartridge fuse has been replaced by an insert (202). This is similarly mounted in the enclosure 1 10, although in this embodiment, the insert fills the entire space within the enclosure, and the space allowed within the plug interior for the fuse, which a typical cartridge fuse may not.
  • the insert in similar fashion to the cartridge fuse it replaced, has contacts on each side of each end, so that it can be electrically coupled to the live pin and the live terminal. This ensures that the overcurrent protection features of the insert can be used, to maintain the plug's protection now that the fuse is removed.
  • the contacts are (additionally or alternatively) on the ends of the insert, or in other forms and positions, adaptable to differing enclosure designs in different plugs.
  • the power management devices of the insert can be powered by a small on-chip battery. Alternatively, they may draw a small amount of power from the live pin, via the contacts. In such an embodiment as the insert is in-line with the positive side it may only be powered when the electrical device is plugged in and working. If unplugged, or turned off (either at the socket or by the insert's on/off switching feature) the insert will not typically be powered.
  • One alternative to this provides a wire from the insert that connects to the negative terminal in the socket, so that power can be drawn from the negative side. An earth connection can be provided if necessary.
  • Figure 3 illustrates one arrangement of the internal components of the insert 202 of Figure 2, here designated 302, in an embodiment of the invention.
  • a printed circuit board 304 runs along the inner length of the insert, here shown side-on, with components of the power management device(a) mounted on both faces.
  • a resettable fuse (308) here a PPTC, provides the overcurrent protection.
  • the PPTC core changes phase on overcurrent, increasing resistance, and later reverts to its normal conducting state once the overcurrent is removed.
  • the PPTC is electrically connected to the PCB and to each end of the insert (for example, via connecting wires 314) so that the inputs to its terminals are (a) the live pin and (b) the live terminal of the plug.
  • a circuit breaker can be used.
  • a resettable breaker can reset automatically (in similar manner to the resettable fuse) once the overcurrent state is removed.
  • a lever on a manual reset breaker can be made accessible on the outside of the insert, or a lever or button can be provided on the outside of the plug, electrically connected through the housing to the breaker of the insert.
  • the breaker may also be resettable remotely, by wireless communication.
  • a simple fuse a blowable fuse wire
  • This provides a cheaper insert.
  • a controller 306 is also mounted on the PCB - this provides the means to switch the power to the live terminal, and hence to the appliance, on and off.
  • the controller 306 can also vary the power output to the live terminal, for example to provide a dimmer for a lamp. Simple transistors/gates and potentiometers can be used as these can be easily miniaturised.
  • some of the functionality of the fuse/breaker 308 and controller 306 can be combined - for example a mechanical trip could be used for the overcurrent protection, and this trip made part of the controller.
  • a metering device (312) is mounted, in electrical contact at least with the live terminal, in order to measure electrical parameters.
  • the overcurrent device 308 if a resettable breaker, can be made to respond to a communication signal from the hub to actuate or reset the breaker.
  • the device 308 can also update the hub with a status (actuated, nominal, reset).
  • the controller 306 similarly can respond to communicated instructions received by the communication device, to turn the power on or off, or provide a dimming effect.
  • the metering device 312 can communicate all measurement data to the hub via the communication device.
  • the metering device can respond to instructions from the hub to measure any of the parameters at a given time (for example instantaneously, to give an up to date reading) or to add or remove measurement of any of the parameters.
  • the communication device (310) may comprise a wired communication line, rather than a wireless transceiver.
  • a power-line communication protocol can be used, such as X10 or a broadband over power-line (BPL) protocol, such as IEEE 1901 .
  • a modulated carrier signal can be transmitted from the communication device via the connecting wires 314, the terminals and the lines installed in a corresponding socket, and thereby around a power-line network (such as that found in a domestic setting) to the hub, and to other devices.
  • a device to generate the modulated signals to transmit the data can be incorporated into the communication device 310.
  • the PCB 304 of the insert 302 is connected to the contacts of the insert by connecting wires 314 at the top and bottom of the board.
  • the connecting wires can connect to the sides of the insert, as shown by the dotted line 316, if the contacts on the insert are on the sides.
  • This embodiment employs a piezoelectric design, where a physical pressing action generates enough energy to briefly send a signal to the insert.
  • This device can be attached to the outside of the plug (for example by peel off backing tape), or even on a wall or other fixture near the plug/socket, for example within a minimum distance of the outlet.
  • This switch may need to be pre-paired with the insert during manufacture, so that communication between the separate switch and the insert is unique to that switch/insert set, to avoid problems where multiple switches and plug inserts exist in a location.
  • the insert may comprise other components, such as those mentioned above but not specifically indicated in Figure 3.
  • the PCB may include a battery or means for drawing power from the live pin.
  • the board may have a processor and/or a storage means mounted on it, for providing storage and processing of programming instructions for devices on the board, so that some instructions do not have to be provided from the hub.
  • the communication device may receive software updates from the hub or from an updating device or network, which updates are then loaded on the storage means and processed by the processor.
  • the hub (not shown) with which the insert communicates has a communication capability, for example a wireless radio device and protocol, a processor and storage for managing data for and from inserts, and for programming control procedures for the inserts and communicating instructions to them.
  • the hub may manage a number of inserts in the installed environment, for example a number of appliances and/or power outlets in a home.
  • the hub may have a physical separate enclosure located in the environment of the inserts/plugs/sockets being used. For example, it may be in a control box located in the home, or incorporated into a fuse box.
  • the hub may also be embodied in a mobile communication device, such as a mobile telephone or tablet device. These would use the communication, processing and storage capabilities already present in that device to manage the system, with software installed on the device in the form of an app.
  • the user may interact with the app or control box view energy usage information, and to program the insert, for example to program switching on/off times for appliances in a home, or to measure energy usage of particular devices at particular times.
  • the aims of the invention can be addressed by simply modifying a plug (or manufacturing a new plug) to include power management features into the plug. This can be done by inserting devices for these features into a plug, for example by simply attaching an additional enclosure onto a plug, and connecting the devices inside to the live pin and live terminal inside the plug. Alternatively a plug could be manufactured with the components installed. This embodiment may be simpler to use for new manufacturing of appliances and their plugs. However, it may be more difficult for end users to change a plug, rather than simply change a fuse for an insert.
  • FIG. 5b One alternative embodiment is illustrated in Figure 5b, below a section of a standard plug in Figure 5a.
  • the cartridge fuse (506) is arranged in an enclosure formed by sprung clamps (504) in contact with the live pin (502) of the plug.
  • the fuse is now clamped by the curved form of the sandwich (512) inserted into the sprung clamps (504), and the fuse is re-inserted into the sandwich clamp.
  • the lower contact of the sandwich is in contact with the live pin (502) via the sprung clamp, and the upper contact of the sandwich is in contact with the fuse. Therefore the fuse becomes in series with the insert device (508) as it has no direct electrical connection with the live pin clamps.
  • the insert is in contact with the live pin in order to make metering measurements.
