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.
