Abstract

A mains interface 6 comprises a means to couple to a battery charger 5; a means such as socket 13 to couple to a device 7 to be charged; means such as a plug connector 9 to couple to a mains supply 2 and a means to electrically isolate the battery charger from the mains supply when the device 7 is not coupled to the interface. An isolation switch (fig 3, 10) can isolate the supply and be operated by a mechanical lever, a button or by magnetism. Forces applied when coupling the device 7 to the socket 13 can operate the isolation switch to couple the charger to the supply and a decoupling force can operate the switch to isolate the charger from the supply. The socket can connect to a specific device or to a series of generic devices such as mobile communication, navigation, entertainment, computing, power tool, torch or toy devices. The interface can couple to an external battery charger, can incorporate a battery charger and the socket 13 can electrically couple device 7 to the charger.

Description

ENERGY SAVING MAINS INTERFACE FOR A BATTERY CHARGER
This invention relates to an energy saving, mains interface that may be used with, or incorporated into, a battery charger.
A problem exists where electrical energy is wasted as a result of a batteiy charger being connected to a mains supply whilst it is off-load (decoupled from the device to be charged).
In the above scenario, electrical energy is wasted when it is leaked, lost or consumed by the battery charger circuitry.
This problem is compounded when one considers the proliferation of chargeable devices in use around the world and how millions, if not billions, of portions of electrical energy are wasted on a daily basis by devices not limited to the following types: * Mobile communication * Navigation * Personal entertainment * Computing * Power tools * Torches * Toys A solution to the problem is to decouple the battery charger from the mains supply when the device is decoupled from the battery charger, however, this is often neglected and some of the reasons why may be as follows: 1 Forgetting 2. Haste 3. Being unaware 4. Being unconcerned These four reasons alone probably account for daily electrical energy losses of Megawatts in the UK and Gigawatts globally.
To overcome this, the present invention proposes a mains interface that will electrically isolate a battery charger from the mains supply when the device to be charged by the battery charger is not coupled to the mains interface.
The mains interface will overcome the problem of wasted electrical energy by eliminating the human factors, detailed in 1 to 4 above, from the battery charger decoupHng process.
Preferably, the mains interlace incorporates battery charging circuitry.
Preferably, the mains interlace incorporates device specific electrical connections.
Preferably, the mains interlace permits practical operation of the device whilst coupled to the mains interface.
Preferably, the mains interlace incorporates a cable management system to enable the cable of an external battery charger to be concealed, stored, wrapped or held in a neat and tidy fashion.
Three examples of the invention will now be described by referring to the accompanying drawings:
Example 1
Figure 1, exploded view, and figure 2, assembled view, are side elevations and figure 3 is a schematic view showing a version of the mains interlace that is equipped with internal battery charging circuitry Icr the purpose of charging the battery of a mobile telephone.
Example 2
Figure 4, exploded view, figure 5 and figure 6, assembled views, are side elevations and figure 7 is a schematic view showing a version of the mains interlace that is equipped with internal battery charging circuitry for the purpose of charging the battery of a mobile telephone. This version enables the mains interface to mechanically decouple from the BS1363 plug so that the telephone may be used whilst being charged.
Example 3
Figure 8, exploded view, and figure 9, assembled view, are side elevations and figure lois a schematic view showing a version of the mains interlace that is equipped with a facility to connect an external battery charger for the purpose of charging the battery of a mobile telephone.
Example I
A BS1 363 type mains socket outlet 2 is shown mounted to a wall 1 The mains interface 6 incorporates: a BS1 363 type plug connector 9 to enable Ito couple to a BS1363 type mains socket outlet 2.
* a socket 13 to enable it to mechanically couple to and mechanically support a mobile telephone 7.
* a battery charger connector 3 to enable it to electrically couple to a mobile telephone 7 via the mobile telephone charger connector 8.
* a normally open, double pole, switch 10 whose contacts will close when a mobile telephone 7 is coupled to the socket 13 and open when a mobile telephone 7 is decoupled from the socket 13.
* battery charger circuitry 11.
* wiring to connect the input of the battery charger circuitry ii to the plug connector 9 via the normally open, double pole, switch 10.
* wiring to connect the output of the battery charger circuitry 11 to the battery charger connector 3.
This version of the mains interface 6 is double insulated and therefore only the live L and neutral N teiminals are detailed in figure 3.
Example 2
A BS1363 type mains socket outlet 2 is shown mounted to a wall 1. The mains interface 6 incorporates: * a set of mains input terminals 17 to enable it to couple to a BS1 363 type mains socket outlet 2 via a two-core flexible cable 15 and BS1 363 Plug 16.
* a socket 13 to enable it to mechanically couple to and mechanically support a mobile telephone 7.
* a battery charger connector 3 to enable it to electrically couple to a mobile telephone 7 via the mobile telephone charger connector 8.
* a normally open, double pole, switch 10 whose contacts will close when a mobile telephone 7 is coupled to the socket 13 and open when a mobile telephone 7 is decoupled from the socket 13.
* battery charger circuitry 11.
* wiring to connect the input of the battery charger circuitry 11 to the mains input terminals 17 via the normally open, double pole, switch 10.
* wiring to connect the output of the battery charger circuitry Ii to the battery charger connector 3.
The BSI 363 plug 16 incorporates an integral bracket 18 to enable it to couple to and decouple from the interface bracket 19. This version of the mains interlaceS is double insulated and therefore only the live Land neutral N terminals are detailed in figure 7.
Example 3
A BS1 363 type mains socket outlet 2 is shown mounted to a wall 1 The mains interface 6 incorporates: a BS1 363 type plug connector 9 to enable Ito couple to a BS1363 type mains socket outlet 2.
* a socket 13 to enable it to mechanically couple to and mechanically support a mobile telephone 7.
* a normally open, double poie, switch 10 whose contacts will close when a mobile telephone 7is coupled to the socket 13 and open when a mobile telephone 7 is decoupled from the socket 13.
* a 8S1363 type mains socket outlet 12 to enable it to couple to an external mains powered battery charger 5.
* wiring to connect the mains socket outlet connector 12 switched live St and switched neutral SIN terminals to the plug connector 9 live L and neutral N terminals via the normally open, double pole, switch 10.
* wiring to connect the earth E terminal of the plug connector 9 to the earth E terminal of the socket outlet connector 12.
