Abstract

The invention relates to a heat-resistant cable for charging a mobile device from a vehicle. In particular, the cable can be used to connect to a power source on a vehicle that does not have a standard cigarette lighter power source. The complete cable can be constructed as a single, continuous, and electrically sealed apparatus, without further interconnections open to the environment between the source connector and the output connector.

Claims

1. A mobile charger apparatus comprising:

a first connector at a source end of the mobile charger apparatus, the first connector having a standardized form factor for connection to a wiring harness that is connected to an electrical lead on a vehicle;

a second connector at an output end of the charger apparatus for electrically connecting a mobile device to the mobile charger apparatus;

a power conversion component that electrically converts a first voltage received at the first connector to a second voltage and provides the second voltage to the second connector;

wherein a cable connecting the first connector at the source end and the second connector at the output end is constructed as a single, continuous, and electrically sealed apparatus, without further interconnections open to the environment between the source connector and the output connector;

and wherein the cable is constructed from heat-resistant materials.

2. The mobile charger apparatus of claim 1, wherein the cable further comprises a para-aramid synthetic fiber runner.

3. The mobile charger apparatus of claim 2, wherein the para-aramid synthetic fiber runner is Kevlar™

.

4. The mobile charger apparatus of claim 1, wherein the cable is constructed so as to withstand a pull force of approximately 100 lbs without breaking.

5. The mobile charger apparatus of claim 1, wherein the first connector interconnects with a Battery Tender™

wiring harness.

6. The mobile charger apparatus of claim 1, wherein the cable is over-molded with thermoplastic polyurethane with a fluoropolymer elastomer heat-shrink to protect against high temperatures.

7. The mobile charger apparatus of claim 1, wherein the cable is constructed of components selected from conductors of solid or stranded wire, insulation of silicone rubber, binders of close weave glass tape, electrostatic screens of aluminum or polyester laminated tape and a sheath of thermoplastic compound.

8. The mobile charger apparatus of claim 1, wherein the first connector is a flat SAE hermaphrodite two-conductor connector.

9. The mobile charger apparatus of claim 1, wherein the first connector comprises components selected from the group consisting of:

a circuit board, a resistor, a capacitor, a transistor, a wire, a semiconductor device, and combinations thereof.

10. The mobile charger apparatus of claim 1, wherein the output end is weather-protected at an interface with the mobile device.

11. The mobile charger apparatus of claim 1, wherein the first connector receives electrical power with a voltage of approximately 12V and the second connector provides electrical power with a voltage of approximately 5V.

12. The mobile charger apparatus of claim 1, further comprising one or more batteries connected to the first connector that supply power to the mobile device charger.

13. The mobile charger apparatus of claim 1, wherein at least one of the first and second connectors is an iOS device type connector.

14. The mobile charger apparatus of claim 1, wherein at least one of the first and second connectors is a USB device type connector.

15. The mobile charger apparatus of claim 1, wherein the mobile charger device comprises a flexible cable.
