A cable connector assembly includes a cable and a connector electrically connected with the cable for further electrically connecting with a power source. The connector includes: a main body; a plurality of contacts retained to the main body; a light emitting element; a printed circuit board (15) for controlling the light emitting element to emit light; and an outer case enclosing the connector and defining an indication area; wherein the connector further includes a conducting member mounted on the printed circuit board (15), the conducting member is a spring plate made of metal material pressing upon the indication area of the outer case, a front end of the outer case defines a transparent portion made of transparent material, and upon pressing the indication area, capacitance is affected and the light emitting element is turned on to emit light through the transparent portion.
