Abstract

The utility model provides a USB interface and a mobile terminal, which are adaptable to the technical field of data communication interfaces. The USB interface comprises a metal interface outer casing and an insulating plate placed inside the metal interface outer casing, and nine contacts connected with USB3.0 control chips are arranged on the insulating plate. As the nine contacts connected with the USB3.0 control chips are arranged on the USB interface, the USB interface is enabled to be adaptable to a USB3.0 standard, thereby enabling the USB3.0 standard to be more effectively popularized and applied.

Description

A kind of USB interface and portable terminal

Technical field

The utility model belongs to the data communication interface technical field, relates in particular to a kind of USB interface and portable terminal.

Background technology

USB (Universal Serial Bus, USB) is a kind of external bus standard, is extensive use of on computers.USB has experienced USB1.0 standard and USB2.0 standard after two stages, the stage of nowadays having developed into the USB3.0 standard.

The USB1.0 standard occurred in 1996, and its transmission rate has only 1.5Mb/s, afterwards, has occurred the USB2.0 standard again, and USB2.0 adopts half-duplex two-wire system bus, and the one-way data flow transmission only is provided, and its transmission rate is 60Mb/s.

But, along with development of times, people are more and more higher to the requirement of message transmission rate, and the transmission rate of USB2.0 standard can not satisfy people's requirement, therefore, people develop the USB3.0 standard, USB3.0 adopts antithesis simplex four-wire system differential signal line, supports two-way simultaneous streaming transmission, and the message transmission rate of USB3.0 standard is than fast ten times of the message transmission rates of USB2.0 standard, and compare with the USB2.0 standard, the USB3.0 standard has higher energy-saving efficiency.

At present also do not develop a kind of USB interface that can be applicable to the USB3.0 standard, badly influenced applying of USB3.0 standard like this.

The utility model content

The purpose of this utility model is to provide a kind of USB interface, is intended to solve present USB interface and has the problem that can not be applicable to the USB3.0 standard.

The utility model is achieved in that a kind of USB interface, and it comprises the metal interface shell and be built in the interior insulation board of described metal interface shell that described insulation board is provided with 9 contacts that are connected with the USB3.0 control chip.

In the said structure, described 9 contacts that are connected with the USB3.0 control chip are respectively power positive end, difference input data anode, difference input data negative terminal, ground-side of power, hypervelocity differential received data anode, hypervelocity differential received data negative terminal, signal ground terminal, hypervelocity difference emission data anode and hypervelocity difference emission data negative terminal.

In the said structure, the plane contact structure is adopted in described 9 contacts that are connected with the USB3.0 control chip.

In the said structure, elastic piece structure is adopted in described 9 contacts that are connected with the USB3.0 control chip.

Another purpose of the present utility model is to provide a kind of portable terminal, and described portable terminal comprises above-mentioned USB interface.

In the said structure, described portable terminal comprises mobile phone, card reader, memory, MP3 and PDA.

In the utility model, USB interface is provided with 9 contacts that are connected with the USB3.0 control chip, makes USB interface can be applicable to the USB3.0 standard, thereby makes the USB3.0 standard to apply better.
