Abstract

A connector in the shape of a standard printed circuit chip card having contact areas joined by conductors and to be used to apply battery recharging energy to an electronic device such as a mobile telephone through a chip card receiving slot in the device. The connector may be fixed to a power source or may be joined by wires to a remote power source. In some embodiments a sleeve to which the wires are fixed may be placed over a standard chip card. This sleeve may be formed with an opening to expose the chip card contacts so that normal operation may be carried out while batteries are being recharged.

Claims

1. A connector comprising a body of non-conducting material, a first group of contact areas on the body, a second group of contact areas on the body and a group of electrical conductors electrically connecting each of the contact areas of the first group to at least one contact area of the second group, the first group of contact areas being arranged to apply electrical charging current through a device slot normally used to receive a standard chip card,

the body having the form of a sleeve having an opening on a side, which opening can be pushed over the standard chip card in a substantially close-fitting manner, the sleeve having a bottom with a predetermined bottom thickness and a top with a predetermined top thickness.

2. The connector according to claim 1, wherein the sleeve is provided with a second opening for exposing chip-card contact areas of the standard chip card when inserted in the sleeve.

4. The connector according to claim 1, wherein the sleeve comprises plastic.

5. The connector according to claim 1, wherein the bottom thickness and top thickness together is not more than 0.1 mm.

3. The connector according to claim 13, wherein the sleeve is provided with further openings for exposing side edges of the chip card when inserted in the sleeve.

6. A system comprising a device and a connector,

the connector comprising a body of non-conducting material, a first group of contact areas on the body, a second group of contact areas on the body and a group of electrical conductors electrically connecting each of the contact areas of the first group to at least one contact area of the second group, the first group of contact areas being arranged to apply electrical charging current through a slot in the device normally used to receive a standard chip card,

the body having the form of a sleeve having an opening on a side, which opening can be pushed over the standard chip card in a substantially close-fitting manner, the sleeve having a bottom with a predetermined bottom thickness and a top with a predetermined top thickness;

and

the device comprising a casing, contact terminals, a chargeable battery having a positive connection and a negative connection which are respectively connected to a first contact terminal and a second contact terminal for supplying electrical energy to the battery in order to recharge it, and the slot for receiving a chip card, wherein the contact terminals are located in the slot so that at least the first and second contact terminals can be brought into electrically conducting contact with the contact areas of the first group of contact areas of the connector when the connector is inserted into the slot.

7. The system according to claim 6, wherein the device is a mobile telephone.

8. The system according to claim 6, wherein the device is an interface for converting electrical signals received from a chip card into audible signals for a telephone earpiece.

9. The system of claim 6, wherein the bottom thickness and top thickness together is not more than 0.1 mm.

10. A power supply having output terminals for supplying power and a connector,

the connector comprising a body of non-conducting material, a first group of contact areas on the body, a second group of contact areas on the body and a group of electrical conductors for electrically connecting each of the contact areas of the first group to at least one contact area of the second group, the first group of contact areas being arranged to apply electrical charging current through a device slot normally used to receive a standard chip card,

the body having the form of a sleeve having an opening on a side, which opening can be pushed over the standard chip card in a substantially close-fitting manner, the sleeve having a bottom with a predetermined bottom thickness and a top with a predetermined top thickness;

and

said output terminals of the power supply being electrically connected to members of said second group of contact areas.

11. The power supply of claim 10, wherein the bottom thickness and top thickness together is not more than 0.1 mm.
