Abstract

There is provided a charger for charging a wearable device, comprising a charger head comprising a first connector with positive polarity; and a second connector with negative polarity, wherein the first connector and the second connector are arc-shaped.

Claims (21)

1. A charger cable for charging a wearable device, comprising

a charger head comprising

a first connector with positive polarity; and

a second connector with negative polarity, wherein the first connector and the second connector are arc-shaped.

2. The charger cable of claim 1 , wherein the arc-shaped connectors are placed symmetrically on the charger head.

3. The charger cable of claim 2 , wherein a surface of the charger head has, at least partly, a concave form for receiving a caseback of the wearable device comprising a surface having, at least partly, a form of a curved dome.

4. The charger cable of claim 2 , wherein the charger head comprises one or more magnets for attracting connectors of the wearable device.

5. The charger cable of claim 2 , wherein the arc-shaped connectors each comprise an end and wherein the charger cable comprises a non-conductive gap between the ends of the arc-shaped connectors.

6. The charger cable of claim 5 , wherein the cable is in a substantially straight angle with respect to an imaginary line traversing through the non-conductive gaps.

7. The charger cable of claim 2 , wherein the first connector and the second connector are concentric arcs separated by non-conductive gaps.

8. The charger cable of claim 1 , wherein a surface of the charger head has, at least partly, a concave form for receiving a caseback of the wearable device comprising a surface having, at least partly, a form of a curved dome.

9. The charger cable of claim 8 , wherein the charger head comprises one or more magnets for attracting connectors of the wearable device.

10. The charger cable of claim 1 , wherein the charger head comprises one or more magnets for attracting connectors of the wearable device.

11. The charger cable of claim 10 , wherein the one or more magnets are arranged under the arc-shaped connectors.

12. The charger cable of claim 1 , comprising non-conductive gap between ends of the arc-shaped connectors.

13. The charger cable of claim 12 , comprising a connector at an end of the cable for connecting the charger cable to a power source or to a transformer.

14. The charger cable of claim 1 , wherein the cable is in a substantially straight angle with respect to an imaginary line traversing through the non-conductive gaps.

15. The charger cable of claim 14 , comprising a connector at an end of the cable for connecting the charger cable to a power source or to a transformer.

16. The charger cable of claim 1 , comprising a connector at an end of the cable for connecting the charger cable to a power source or to a transformer.

17. The charger cable of claim 1 , wherein the first connector and the second connector are concentric arcs separated by non-conductive gaps.

18. The charger cable of claim 1 , wherein the arc-shaped connectors each comprise an end and wherein the charger cable comprises a non-conductive gap between the ends of the arc-shaped connectors.
