Background technology
In the information age, the importance of data transmission is self-evident, the parts such as data cube computation to the transmission of this its real data
Line is requisite.The most common data wire mainly has Shielded Twisted Pair, coaxial cable, three kinds of optical cable.Shielding
Twisted-pair feeder, data line line being made up of many.Its feature is exactly low price, so being widely used, such as me
Common telephone wire etc..It is used to be connected with RJ45 connector.It has again STP and UTP two kinds, and what we commonly used is
UTP.Netting twine is by eight copper conductors, in order to reduce interfering of electromagnetic signal, presses certain density snarl together for every two.
So, the electric wave that spoke body goes out each other when transmitting telecommunication will be cancelled out each other, and effectively eliminates interference.Shielded Twisted Pair
This name also in that such structure and extend out.In outside, there are one layer of toughness and the protection of high protection crust.Screen
Cover twisted-pair feeder use the earliest and be used to the transmission of telephone signal, the most just worked as by the transmission being gradually incorporated into digital signal
In, a long time ago, we are essentially all 3 type shielding twisted-pair feeders of use, and maximum can only achieve the bandwidth of 16Mbps, and shows
The most widely used at us is all super Category 5, Shielded twisted-pair feeder and six type shielding twisted-pair feeders.Maximum can reach
The bandwidth of 1000Mbps.But find in place of some shortcomings during our every day use: parcel very tight, do not have good
Good heat dispersion and shock-absorbing capacity.
Summary of the invention
For above-mentioned prior art, present invention aim at providing a kind of shock resistance data connecting line, it is possible to solve existing
The heat dispersion that exists of data connecting line and the bad problem of shock-absorbing capacity, and there is simple in construction, advantage that reliability is high.
For reaching above-mentioned purpose, the technical solution used in the present invention is as follows:
A kind of shock resistance data connecting line, including the insulating barrier wrapped up the most successively, fire lagging, metal protection
Layer and silicone rubber inner sheath；Being provided with filler layer inside silicone rubber inner sheath, silicone rubber inner sheath is provided with cross section along inner surface and is
Four silicone rubber projections of arc, each silicone rubber lobed interior is provided with buffer cavity, forms card between adjacent silicon rubber bumps
Groove, is provided with the Shielded Twisted Pair group being simultaneously against on filler layer in each draw-in groove, Shielded Twisted Pair group includes extruding bar, around
Extruding bar is provided with four groups of Shielded Twisted Pairs, and four groups of Shielded Twisted Pairs are externally provided with closely pastes extruding bar and four groups of Shielded Twisted Pairs
The silastic material being combined.
Further, insulating barrier includes one layer of composite fire band and lays respectively at the inside and outside all composite fire bands
One gold mica tape, the second gold mica tape, the first gold mica tape, composite fire band and the second gold mica tape are wrapped in metal successively to be prevented
Insulating barrier is formed on the outer peripheral face of sheath.
Further, be provided with outside insulating barrier be added with capsaicin only nibble layer, it is possible to solve cable be easily subject to Mus,
Biting of ant etc., the problem causing cable failure, product reliability difference.
Compared with prior art, beneficial effects of the present invention:
In the present invention, Shielded Twisted Pair group is by being arranged at the silicone rubber inner sheath four silicone rubber projections along inner surface
It is securely fixed within it, by increasing frictional force, improve integrally-built stability, and arrange in silicone rubber projection
Buffer cavity, adds the shock-absorbing capacity of structure, reduces outside huge power to the impact of Shielded Twisted Pair group, destruction, and also has
Help the heat radiation of data connecting line；Inside silicone rubber inner sheath, it is provided with filler layer, is allowed to fix with silicone rubber male cooperation
Live Shielded Twisted Pair group, further promote its stability.
