Abstract

A cable connector assembly (100) includes: a cable (30) having a number of inner wires; a first connector (10) including a main body (120), plural contacts (121) retained in the main body, a first circuit board (130), a luminous element (152), and a cover; and a second circuit board (180) assembled on a rear end of the first circuit board and getting power and grounding source from the first circuit board. The second circuit board includes a detection contact (182) electrically connected to an inner wire of the cable, and a chip (181) electrically connected respectively to the luminous element and the detection contact. The chip detects a voltage difference between the power source and the first connector. A light is emitted by the luminous element passing through the cover to indicate a charging status of the charging device.
