cable connector

Abstract

A cable connector comprises a connector male head, a circuit board and a cable. Upper conductive terminals and lower conductive terminals respectively include two pairs of high-speed difference signal terminals used for transmitting high-speed difference signals; the circuit board includes a first surface-conductive layer, a second surface-conductive layer and at least one intermediate conductive layer, and multiple front-side bonding pads, multiple rear-side bonding pads and multiple conductive circuits are formed on the two surface-conductive layers; a public grounding area is arranged on each of the intermediate conductive layers, and the public grounding area partitions the rear-side bonding pads located on the first surface-conductive layer and used for transmitting the high-speed difference signals and the rear-side bonding pads located on the second surface-conductive layer and used for transmitting the high-speed difference signals in an upper and down manner; the rear-side bonding pads located on the first surface-conductive layer and used for transmitting the high-speed difference signals and the rear-side bonding pads located on the second surface-conductive layer and used for transmitting the high-speed difference signals are mutually staggered on the vertical projection direction. The cable connector is applicable to reduction of background noises.

Description

technical field [0001] The invention relates to a cable connector, in particular to a cable connector suitable for high-speed data transmission. 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 terminal unit includes an int...

AI Technical Summary

Problems solved by technology

The conductive line layer on the component board of this micro-USB connector is one-to-one and straightly extends back and forth. Due to the dense spacing between 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 of the upper conductive layer on the circuit board of this connector and the conductive circuit layer of the lower surface conductive layer of the circuit board, and it is easy to interfere with each other during high-speed data transmission, resulting in crosstalk problems.
