DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring toFIGS. 1 to 3, a cable connector in the present invention includes a first plug1, a second plug2opposite to the first plug1, and a cable3connecting the first plug1and the second plug2.

The first plug1is used for docking with an electronic product to be charged and includes a shell11, a housing12received in the front end of the shell11, a cover13received in the rear end of the shell11and LED light14received in the shell11.

The second plug2is for connecting to a power source.

The cable3is a USB 2.0 cable. The cable3includes a power wire31, a ground wire32, a data transmission wire33, a shielding layer34covering outside of the power wire31, the ground wire32, and the data transmission wire33, a first (insulative) outer layer35located outside the (inner) shield layer34, a metal braid or (outer) shielding layer36located outside the first outer layer35, a second (insulative) outer layer37located outside the metal braid layer36and a braid layer38located outside the second outer layer37. The power wire31includes a positive pole and a negative pole. The positive pole includes a conductor and an inner insulating layer coated on the outer side of the conductor. The ground wire32is a bare conductor. The data transmission wire33includes a plurality of differential signal wires and an insulating layer wrapped on the outside of the differential signal wires. The data transmission wire33includes a plurality of differential signal wires and an insulating layer wrapped on the outside of the differential signal wires. The shielding layer34is an aluminum foil Mylar layer and includes an AL (Aluminum Foil) and a PET (Polyethylene terephthalate) material. The braid layer38is located on the outermost side of the cable3and is composed of metal enameled wire hybrid fibers. The cable3further includes a filling body39located inside the shielding layer34, which makes the cable3more rounded and increases the breaking force of the cable3.

The cable connector100further includes a printed circuit board provided with a chip. The LED light14is located on the printed circuit board. When the second plug2is connected to the power and a voltage is applied to the braid layer38, the surface of the braid layer38forms a capacitance and produces a uniform electrostatic field. In the range of 15 cm from the cable3, when the user (such as a human finger) approaches, the local electric field of the capacitance of the surface of the braid layer38is changed, and the two poles of the electric field of the capacitor are changed. The chip outputs a signal to the LED light14by reading a change in the electric field value of the capacitor, triggering the LED light14to emit light, so that in the case of black or dim light, the charging port of the cable connector100can be found more easily by simply approaching the cable3for accurate docking.
