Description
Technical field:
The utility model relates to the telecommunication cable technical field, especially relates to a kind of digital communication high performance cable
Background technology:
Along with the continuous development of digital transmission technology and the application of 3G network in the world, people require also more and more higher to the product quality of cable for digital communication, Defence business and user propose the demand cable for digital communication, and be especially more urgent to the demand of high-performance six class telecommunication cables.
Use in the process of transition to gigabit at network, network is higher to the requirement of bandwidth, and the performance that any impropriety that means generation, the fixing link of cable all can cause connecting up can't satisfy whole requirements of express network.At this moment line between isolation technology begin to adopt, common cable generally adopts be line between a word isolation technology, though improved the electric property of cable to a certain extent, also to line between play buffer action, its weak point is: 1, for crooked situation roll off the production line between the maintenance of relative position on certain defective is arranged.2, the line after isolating is not adopted the shielding external electromagnetic field, influence the echo and the fade performance of telecommunication cable.
The utility model content:
The purpose of this utility model is to provide a kind of environment-friendly and high-performance six class telecommunication cables, its advantages of good shielding performance, and cable signal loss in transmission course is little, has lightning-arrest function, and easy construction has reduced production cost simultaneously.
Technology solution of the present utility model is as follows:
Environment-friendly and high-performance six class telecommunication cables, include the outer quilt of sheath, four pair cable lines are distributed on four fens spaces that isolate cruciform skeleton, shielding aluminium is thin to be coated on outside four pair cable lines, the bare metal ground wire place shielding aluminium thin in, the thin outer quilt of sheath that is coated with of shielding aluminium is coated with steel wire self-supporting line in the outer quilt of sheath.
Coat clamping between outer quilt of described sheath and shielding aluminium are thin tear line is arranged.
The beneficial effects of the utility model are:
1, shielding aluminium is thin has played good electromagnetic shielding protective effect to the pair cable line, in transmission course the loss of signal little, be subjected to external interference little, guarantee the transmission signals quality.
2, be provided with the bare metal ground wire in shielding aluminium is thin, the bare metal ground wire has the effect of lightning rod, and at the weather that thunders, cable transmission is not influenced by thunderbolt.
3, tear line makes things convenient for user's strip off cable, easy construction.
4, be coated with steel wire self-supporting line in the outer quilt of sheath.Pulling cable during convenient construction makes that cable cover(ing) is outer to be unlikely in work progress that relay is excessive breaks or stay crackle because of being subjected to, and causes in the future and seeps water.
5, for the ease of distinguishing, each pair cable line is respectively different colors.During the wiring of pair cable line, the user comes into plain view.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a sectional view of the present utility model.
Embodiment:
Therefore the following stated only for embodying the preferred embodiment of the utility model principle, does not limit protection range of the present utility model.
See shown in Figure 1: environment-friendly and high-performance six class telecommunication cables, it is outer by 10 to include sheath, four pair cable lines 30 are distributed on four fens spaces that isolate cruciform skeleton 20, shielding aluminium thin 50 is coated on outside four pair cable lines 30, bare metal ground wire 60 places in the shielding aluminium thin 50, it is outer by 10 that shielding aluminium thin 50 is coated with sheath, and sheath is outer to be coated with steel wire self-supporting line 70 in 10.
Described sheath outer by 10 with shielding aluminium thin 50 between the coating clamping tear line 40 is arranged.
Operation principle: its four pair cable lines 30 place in the shielding aluminium thin 50, and the thin 50 pairs of pair cable lines 30 of shielding aluminium have played good electromagnetic shielding protective effect, in transmission course the loss of signal little, be subjected to external interference little, guarantee the transmission signals quality.
Be provided with bare metal ground wire 60 in shielding aluminium thin 50, bare metal ground wire 60 has the effect of lightning rod, and at the weather that thunders, cable transmission is not influenced by thunderbolt.
Tear line 40 makes things convenient for user's strip off cable, easy construction.
Sheath is outer to be coated with steel wire self-supporting line 70 in 10.Pulling cable during convenient construction makes that cable cover(ing) is outer to be unlikely in work progress that relay is excessive breaks or stay crackle because of being subjected to, and causes in the future and seeps water.
For the ease of distinguishing, each pair cable line 30 is respectively different colors.During 30 wiring of pair cable line, the user comes into plain view.
The utility model by the network cable conductor diameter is strengthened (0.6 ± 0.005cm) and select the better PE Insulation Material of dielectric constant low insulation performance for use, by optimisation technique technology, reduced decay, distortion index in the product electric property.
The utility model adopts " adhesion line to " technology, with two plastic extruding machines co-extrusion on a head, same line is thoroughly done away with the edge heart yearns to two extrude synchronously, with its stranded being sticked together.Be better than the general network cable under the smaller situation of some angle of bend, the change of line can occur, thereby influence the electric property of cable lay.Through adhesion line to after cable when construction cable geometry change hardly along cable length, can guarantee the stability of characteristic impedance, and characteristic impedance is a parameter that can finally embody the backflow loss., can guarantee that line to stability of structure, improves the uniformity of impedance by retention wire to the stability of two conductor centre-to-centre spacing, thereby improve the index of return loss after the adhesion between line by strand.
The outer environmental protection low smoke and low halogen polyolefine material that is used of the present utility model, pass through process modification, guaranteed that tensile strength is not subjected to external invasion and attack, and the light specific gravity of this material, saved manufacturing cost, the surface aesthetic of cable and good economy performance, environment-friendly materials are nontoxic little to the human injury, and construction easily.
