Description

Technical Field

[0001] The utility model relates to the technical field of lightning interfaces, and more specifically to a lightning signal hub. Background Art

[0002] Since Intel opened Thunderbolt technology to the USB-IF Association, Thunderbolt technology has become more popular, and Thunderbolt computers and peripheral Thunderbolt devices have increased. Due to the popularity of Thunderbolt technology, after computers use Thunderbolt interfaces, usually a Thunderbolt computer has only two Thunderbolt interfaces, and other interfaces are becoming less and less, so these computers are in great need of expansion to connect more external devices.

[0003] Traditional expansion methods include docking stations and USB hubs. USB hubs cannot connect to Thunderbolt interfaces. A docking station is a conversion device that converts one interface into multiple different types of interfaces. A docking station has at most two Thunderbolt interfaces, one for connecting to a Thunderbolt computer and the other for connecting to a Thunderbolt terminal device. Therefore, a docking station can only connect to one Thunderbolt terminal device at most, and cannot connect to multiple Thunderbolt terminal devices, nor can it connect to a display device and a Thunderbolt terminal device at the same time. In addition, the transmission rates of existing docking stations and USB hubs are relatively limited. The current maximum rate can only reach 40Gbps. If you want to use it to transmit and display multiple high-definition and high-refresh images, such as 2 4K / 120Hz or higher images, this bandwidth is far from enough to meet the needs. If you use a traditional docking station to connect a computer to charge the computer, the current maximum charging power can only reach 100W. The charging power is not high, and the charging time is prolonged. With the rapid technological updates today, the demand for large-capacity storage and large-capacity data copying and transmission is also increasing significantly. We are currently in an era where large-capacity storage devices are numerous and indispensable. We are in urgent need of a lightning signal hub that can transmit at a faster rate and can adapt to connect a variety of devices. Utility Model Content
