Description
[technical field]
The invention relates to a kind of micro coaxial cable connector assembly, refer in particular to a kind of micro coaxial cable connector assembly that can transmitting optical signal.
[background technology]
Personal computer uses multiple technologies that the input and output of data are provided at present.PC framework USB (USB (universal serial bus)) is a kind of transmission standard that applies to computing machine and consumer electronics.World-renowned counter and communication common carrier are combined and have been set up USB association (USB-IF), and have set up USB interface specification.USB interface can apply to: mouse, keyboard, electronic notebook, game machine, scanner, digital camera, printer, External memory equipment, networking component etc.
USB supports three kinds of message transmission rates: 1) speed is the low-speed mode of 15Mbit/s (187.5KB/s), and it is used and human interface device pattern, for example: keyboard, mouse, operating rod.2) speed is the full-rate mode of 12Mbit/s (1.5MB/s).Before USB2.0 standard, be that the fastest transfer efficiency and many device datas are lower than full speed mode transfer efficiency at full speed.Equipment is cut apart the bandwidth of USB to arrive first the principle first passing at full speed, but the situation of the effective utilized bandwidth of equipment is not common yet at one time.All USB port supports are mode transfer efficiency at full speed.3) up to 480Mbit/s (60MB/s) fast mode transfer efficiency.But on much equipment.Typical high-speed transfer can only reach the half (60MB/s) of gross data transfer rate.Most of attainable high speed USB device transmission speed is quite slow, conventionally about 3MB/s, and the data transmission rate that sometimes also can reach 10-20MB/s is enough for some equipment, but can not meet all devices requirement.But, in the transmission of audio and video frequency signal, conventionally need to be up to 100MB, even need 1 to 2GB.So current USB transfer efficiency is inadequate.Therefore the bus transfer of contacting is faster used to meet the different needs, for example PCI-Express (transfer efficiency can reach 2.5GB/s), SATA (transfer efficiency can reach 1.5GB/s and 3.0GB/s).
From electric utilization angle, the transmission interface of above-mentioned non-usb protocol can obtain the utilization of wider side.So true really not so, USB connector has all been installed on many mancarried devices, instead of non-USB connector.An important reason is that these non-USB connector comprise more signal terminal, and volume is also larger.For example, in the time that PCI-E is used to provide high speed transmission data efficiency, the connector of 26 terminals and wider clamping structure have limited the use of depositing soon card.Another one example, SATA has used two connectors, and the connector of 7 terminals, transmits for signal.The connector of 15 terminals of another one, for power delivery.Due to these factors, SATA is more widely used in storage inside instead of external unit.
Existing USB connector has little volume, but low transfer rate.But other non-USB connector (PCI-E interface, SATA interface) has high transfer rate, but large volume.They are not suitable for Modern High-Speed equipment, compact electric apparatus device and peripherals.Have small size and meet the connector of high-speed transfer efficiency, portable is very necessary.
In recent years, increasing electronic equipment was used in optical data transmission.Combine and apply on connector if can realize electronic signal and optical signal transmission, will meet the different needs.A kind of both can transmission of electric signals also can transmitting optical signal connector progressively find application.This connector comprises the some metal terminals that are arranged on an insulating body, and some are assembled in hoop part and are arranged on the lens on this body.A kind of hybrid fiber, includes the optical fiber of the metal core wire being connected with metal terminal to be connected with lens subassembly in time.
But lens of the prior art can not float and be fixed on insulator.If there are some tolerances in manufacture process, they will can not accurately dock, and realize the transmission of light signal.
Therefore, be necessary existing connector to be improved to overcome defect described in prior art.
