Horizontal lying-type electric connector
Technical field
The utility model relates to technical field of electric connectors, more particularly, to horizontal lying-type electric connector.
Background technique
In electric connector, as PCI-Express (peripheral component interconnect express) is
A kind of high speed serialization computer expansion bus standard.Compared with PCI-E 2.0, the target of PCI-E 3.0 is that bandwidth continuation is double
Reach 10GB/s, to realize that this target will improve speed, the signal frequency of PCI-E 3.0 is increased to from 2.0 5GT/s
8GT/s, encoding scheme also become more efficient 128b/130b from original 8b/10b, other specifications are basically unchanged, each cycle according to
So 2 data of transmission support multi-channel parallel transmission.Other than the double bring data throughout of bandwidth greatly improves,
Faster, correspondingly the delay of data transmission also can be lower for the signal speed of PCI-E 3.0.In addition, being directed to software model, power consumption pipe
Reason etc. also has specific optimization.In brief, just as expressway, vehicle runs much faster PCI-E 3.0, and the departure interval is more
Low, seat is more comfortable.However, existing 3.0 electric connector of PCI-E assembling production and using on there is also deficiency, need into
One step is improved, and is used with meeting electronic equipment upgrading.
