Connector construction
Technical field
The present invention is a kind of connector construction, and espespecially a kind of signal terminal that utilizes is as charging terminal, and can pass through large electric current, reaches the connector plug structure of quick charge purpose.
Background technology
USB (Universal Serial Bus; USB) connector, generally be commonly referred to as USB connector, because it has the characteristics such as plug and play, transmission speed be fast, applied to widely on the signal transmission of each occasion, and along with the development of USB connector, people have had more demand for transmission speed, stability.
And at present on the market the USB2.0 that use more as coffret, along with day by day popularizing and the continuous expansion of transfer files of digital multimedia, the demand of USB2.0 on can't satisfying the market.And USB3.0 has backward compatible characteristic, and have the ease for use of traditional USB technology and the function of plug and play concurrently, the target of this technology is to release than the fast product more than 10 times of present connection level, adopt the framework identical with existing USB, except USB is optimized, realizing outside lower energy consumption and the higher protocol efficiency, and support following Optical Fiber Transmission, compared to the transmission speed 480Mbps of USB2.0, the transmission speed of USB3.0 can reach 5Gbps.
And along with the action electronic product towards light, thin, short, little trend development, the standard of more USB connector is published out, Micro-USB connector standards for example, this standard substitutes Mini-USB on the electronic product in action, than Mini-USB, it has the more light and handy volume of more traditional Mini-USB connector, and it highly reduces by half, width is very nearly the same, has been the standard interface of the transfer of data of action electronic device and charging.
The user can utilize the Micro-USB connector to be used as data transmission interface or the charging purposes of action electronic device, yet, the electric current that existing Micro-USB connector can bear is less, and has caused the charging rate of action electronic device slow, and necessity of improvement is arranged in fact.
