cable connector

Abstract

A cable connector comprises a connector male joint, a circuit board and a cable, wherein the circuit board is provided with a first surface conductive layer and a second surface conductive layer. A plurality of front pads and a plurality of back pads are respectively formed on the first surface conductive layer and the second surface conductive layer. The front pad comprises four front power supply pads which are used for correspondingly welding four power supply terminals. The distance between two adjacent back pads of the circuit board is larger than that between two adjacent front pads. The back pad comprises a back power supply pad. The welding area of the back power supply pad is larger than that of the front power supply pad. The circuit board is also provided with a first middle conductive layer and a plurality of through holes which vertically penetrate through the circuit board. The first middle conductive layer is provided with a common power supply pool area. The four front power supply pads and one back power supply pad are electrically connected with the common power supply pool area through several through holes. The cable connector is suitable for high-speed transmission and has an advantage of high convenience in manufacture.

Description

technical field [0001] The invention relates to a cable connector, in particular to a cable connector suitable for high-speed data transmission and easy to manufacture. Background technique [0002] Chinese patent CN201420267847.1 discloses a miniature USB reversible male connector, which includes an upper terminal unit, a lower terminal unit, a metal shield, two anti-vibration units, a hollow insulating body, a shell and a component board. The upper terminal unit, the lower terminal unit and the metal shielding sheet are fixedly connected together and inserted into the insulating body. The metal shielding sheet is arranged between the upper terminal unit and the lower terminal unit. The upper terminal unit includes an integrally formed upper base and an upper terminal group, the upper terminal group is embedded in the upper base, and its two ends protrude out of the upper base. The rear section of the upper base is provided with a first installation part. The lower termi...

AI Technical Summary

Problems solved by technology

The conductive circuit layer on the component board of this micro-USB connector is one-to-one and straightly extends forward and backward. When this micro-USB connector is connected to the cable, it needs to be welded on the rear of the component board with the same number of conductive terminals. However, due to the dense spacing of the rear pads on the conductive circuit layer, the process of soldering the connecting wires is quite troublesome and prone to defective products

In addition, there is no shielding design between the conductive circuit layer on the upper surface of the circuit board of this connector and the conductive circuit layer on the lower surface of the circuit board, and it is easy to interfere with each other during high-speed data transmission, resulting in crosstalk problems.
