Abstract

The invention discloses a USB A male head connector. The USB A male head connector comprises a first high-frequency differential signal transmission conductor pair, a second high-frequency differential signal transmission conductor pair, a first power supply transmission conductor, a second power supply transmission conductor, a low-frequency signal transmission conductor pair and a grounding transmission conductor, wherein the first power supply transmission conductor and the second power supply transmission conductor are respectively arranged at the inner sides of the first high-frequency differential signal transmission conductor pair and the second high-frequency differential signal transmission conductor pair; the grounding elastic contact part of the grounding transmission conductorcan abut against the outer shell of a female seat connector through the grounding terminal of the female seat connector when the grounding elastic contact part is in butt joint with the female seat connector, and the grounding connection part of the grounding transmission conductor only extends to a position between a low-frequency signal plate-shaped contact pair. Therefore, high-frequency noisescan be isolated by utilizing the potential difference of the power supply transmission conductors, and meanwhile, interaction influence on the high-frequency differential signal transmission conductors caused by the grounding transmission conductor due to a crosstalk problem can be avoided.

Description

technical field [0001] The invention relates to a USB A male connector, in particular to a USB A male connector which can provide better high-frequency shielding effect and solve the problem of amplified crosstalk of grounding terminals. Background technique [0002] The universal serial bus connector has the advantages of plug-and-play and high-speed transmission, and the transmission capacity of USB has made great progress since the newly developed USB1.0 specification to the current MicroUSB3.0 specification. applied to electronic products. The USB-related transmission protocol is a specification formulated by the USB Association (USB Implementer Forum Inc. USB-IF). All USB connectors must comply with this specification before they can communicate with other USB connectors. [0003] As far as USB3.0 TypeA is concerned, in the past, in order to suppress the problem of high-frequency noise, a large number of improvements to the grounding terminal were used for shielding.
