Abstract

The present invention relates to a cable structure with indicating function, which comprises a cable, a first connector plug and an indication unit. The first connector plug has a main body and a connection part, and coupled with one end of the cable; and the indication unit is fastened in the main body and installed with at least an indicating device coupled with a circuit board and having an indicating function on the main body, the circuit board is connected to a power circuit between the cable and the first connector plug through a wire, and through a detecting circuit of the circuit board performing a comparison operation, the indicating device is enabled to respectively display the indication of charging in progress and charging finished. As such, a user can directly observe the charging status of the hand-held device through the display of the indication unit without needs of actuating the screen of the hand-held device.

Claims

1. A cable structure with indicating function, comprising:

a cable having a plurality of conductive wires located therein, a first connector plug located on a first end of the cable and connected to the plurality of conductive wires, and a USB connector located on a second end of the cable and connected to the plurality of conductive wires;

the first connector plug having a main body, a connection part, and an indication unit located in the main body thereof, the indication unit having a circuit board, at least one indicating device coupled with the circuit board and having an indicating function on said main body of the first connector plug, said circuit board being connected to a power circuit between said cable and said first connector plug through a wire, and through a detection circuit of said circuit board performing a comparison operation on a voltage or a current, said indicating device being enabled to respectively display an indication of charging in progress or charging finished based on the comparison operation when the cable is used in a charging process, and an indication of data transferring in progress or data transfer finished based on the comparison operation when the cable is used in a data transfer process.

2. The cable structure with indicating function as claimed in claim 1, wherein said first connector plug is a dock connector.

3. The cable structure with indicating function as claimed in claim 1, wherein said first connector plug is selected from a group consisting of a standard, mini and micro USB connector.

4. The cable structure with indicating function as claimed in claim 1, wherein said indicating device is selected from a group consisting of an indication lamp and a liquid crystal display.

5. The cable structure with indicating function as claimed in claim 1, wherein the USB connector is coupled with a power adapter.

6. The cable structure with indicating function as claimed in claim 1, wherein the USB connector is coupled with a second connector plug.

7. The cable structure with indicating function as claimed in claim 6, wherein said second connector plug is selected from a group consisting of a standard, mini and micro USB capable of being inserted in a connector socket of a computer or a power adapter.
