DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 to 3, a cable connector in the present invention includes a first plug 1, a second plug 2 opposite to the first plug 1, and a cable 3 connecting the first plug 1 and the second plug 2.

The first plug 1 is used for docking with an electronic product to be charged and includes a shell 11, a housing 12 received in the front end of the shell 11, a cover 13 received in the rear end of the shell 11 and LED light 14 received in the shell 11.

The second plug 2 is for connecting to a power source.

The cable 3 is a USB 2.0 cable. The cable 3 includes a power wire 31, a ground wire 32, a data transmission wire 33, a shielding layer 34 covering outside of the power wire 31, the ground wire 32, and the data transmission wire 33, a first (insulative) outer layer 35 located outside the (inner) shield layer 34, a metal braid or (outer) shielding layer 36 located outside the first outer layer 35, a second (insulative) outer layer 37 located outside the metal braid layer 36 and a braid layer 38 located outside the second outer layer 37. The power wire 31 includes 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 wire 32 is a bare conductor. The data transmission wire 33 includes a plurality of differential signal wires and an insulating layer wrapped on the outside of the differential signal wires. The data transmission wire 33 includes a plurality of differential signal wires and an insulating layer wrapped on the outside of the differential signal wires. The shielding layer 34 is an aluminum foil Mylar layer and includes an AL (Aluminum Foil) and a PET (Polyethylene terephthalate) material. The braid layer 38 is located on the outermost side of the cable 3 and is composed of metal enameled wire hybrid fibers. The cable 3 further includes a filling body 39 located inside the shielding layer 34, which makes the cable 3 more rounded and increases the breaking force of the cable 3.

The cable connector 100 further includes a printed circuit board provided with a chip. The LED light 14 is located on the printed circuit board. When the second plug 2 is connected to the power and a voltage is applied to the braid layer 38, the surface of the braid layer 38 forms a capacitance and produces a uniform electrostatic field. In the range of 15 cm from the cable 3, when the user (such as a human finger) approaches, the local electric field of the capacitance of the surface of the braid layer 38 is changed, and the two poles of the electric field of the capacitor are changed. The chip outputs a signal to the LED light 14 by reading a change in the electric field value of the capacitor, triggering the LED light 14 to emit light, so that in the case of black or dim light, the charging port of the cable connector 100 can be found more easily by simply approaching the cable 3 for accurate docking.
