Abstract

The invention discloses a USB A female seat connector. The USB A female seat 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 groundingtransmission 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 conductor can abut against the outer shell of a male head connector when the grounding elastic contact part is in butt joint with the male head connector, and the grounding plate-shaped contact part of thegrounding transmission conductor abuts against the grounding terminal of the male head connector when being in butt joint with the male head connector. Therefore, high-frequency noises can be isolatedby utilizing the potential difference of the power supply transmission conductors, and meanwhile, interaction influence on the high-frequency differential signal transmission conductors caused by thegrounding transmission conductor due to a crosstalk problem can be avoided.

Description

technical field [0001] The invention relates to a USB A female connector, in particular to a USB A female 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. It is widely used in electronic products. The USB-related transmission protocol is a specification formulated by the USB Association (USB ImplementerForum 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...
