The accompanying drawing explanation
The schematic cross-section that Fig. 1 is super-six type unshielded data telecommunication cable of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Figure 1, this super-six type unshielded data telecommunication cable, the outer jacket 1 that comprises inner core and be coated on the inner core outside, this inner core comprises fills skeleton 2 and four groups of twisted pair wires 3.The skeleton that this filling skeleton 2 is a cross section across, and the inner chamber of outer jacket is separated into to four spaces, be equipped with one group of twisted pair wire 3 in each space.Described outer jacket 1 is polyvinyl chloride (PVC), fluorine moulds fat (FEP) or Halogen material (LSZH) is made.
The length of criss-cross two main bones of this filling skeleton 2 is 6.6mm-6.8mm, and the thickness of this filling skeleton 2 is 0.5mm-0.7mm.And criss-cross four ends of this filling skeleton 2 are respectively equipped with the edge vertical with this criss-cross end 21.The width at this edge 21 is 1.1mm-1.3mm, and this edge 21, centered by the criss-cross end of correspondence, extends to both sides respectively.The separation that this novel filling skeleton 2 keeps every group of twisted pair wire 3 effectively, and position interfixes each other, make this cable that more stable input impedance and return loss performance be arranged, this novel filling skeleton 2 has been avoided fully contacting of outer jacket that dielectric constant is large and twisted pair wire 3 in addition, increased the void area of twisted pair wire, reduced substantially the dielectric constant in each space, effectively improve the decay of every group of twisted pair wire, fill skeleton 2 the pair twist group is effectively separated, thereby improve electromagnetic interference.While is due to the shape at the edge 21 of this novel filling skeleton, edge 21 thickness are the ingehious design that 0.6mm and edge 21 width are 1.2mm, can not only solve electromagnetic interference in the group between the line group of cable inside, effectively interval from a part of electromagnetic interference between adjacent cables.The material of described filling skeleton 2 is that polyethylene (PE), fluorine are moulded fat (FEP) or Halogen material (LSZH) is made.
Every group of twisted pair wire 3 is by two wire twisted together compositions, every wire comprises the conductor 31 in the middle of being positioned at and is coated on the insulating barrier 32 in conductor 31 outsides, the hypoxemia that conductor 31 is 2.6mm by diameter or oxygen-free copper bar are made through wire drawing, annealing, and wire gauge is 23AWG; Insulating barrier 32 is moulded fat (FEP) material by high density polyethylene (HDPE) (HDPE) or fluorine and is made, and insulating barrier 32 thickness are 0.23mm-0.27mm.
Two wires of twisted pair wire 3 are the twisting shape, and four twisted pair wires all adopt 25%～50% back twist technology, the pitch of this twisted pair wire 3 is less than the pitch of conventional six class lines, pitch range is 7mm-10mm, and the pitch of four groups of twisted pair wires 3 is all not identical, adopt fine pith and back twist technology, make communication cable of the present utility model that stronger anti-electromagnetic interference capability, more stable input impedance and return loss performance be arranged in whole frequency range.
The medial surface of outer jacket 1 be evenly distributed with sawtooth the cross section of this medial surface be profile of tooth, and preferably, be 12 sawtooth.The height of this sawtooth is 0.5mm-0.7mm, and the thickness apart from the outside of outer jacket 1 at the bottom of tooth is 0.4mm-0.6mm, and the average wire diameter of this outer jacket is 8.5mm-9.1mm.Too much and the too high increase that all can bring cable cost, the utility model, from the Performance and Cost Modeling in conjunction with cable, is preferentially chosen above-mentioned size to sawtooth.It is circular cable that oversheath coats the cross section formed with 12 sawtooth spaces after inner core, cable cost is not only saved in the sawtooth space, but also increased void area, reduced substantially dielectric constant, effectively improve cable attenuation, 0.5mm-0.7mm the sawtooth height increased by adopted two sheaths could increase the way of the outside diameter of cable in the past, this inner surface be jagged cable and adjacent cable can increase while combining the adjacent cables center line between distance, therefore fill cross-interference issue between the group that can effectively improve super Class 6 cable under skeleton and this dual effect of zigzag outer jacket at cross, not only have advantages of that wire diameter is little, especially there are between the increase group along with frequency the more and more less characteristics of crosstalking. and handling ease, material is economized.And can be provided with one and tear rope 4 in outer jacket.
Super-six type unshielded data telecommunication cable of the present utility model, by crossing skeleton and inner surface, be that jagged outer jacket changes the distance between adjacent cables, effectively prevent external electromagnetic interference by the distance that increases adjacent cables, flexibility while having increased wiring, and improved and adopted two covers to increase the purpose of the outside diameter of cable in the past, thereby reduced cable cost.The mechanical performance of this cable product, electric property and fire-retardant fireproof performance all can meet the requirement of the aspects such as the industrial standard of World Developed Countries and flame-retardant standard; Have advantages of easy to use, be convenient to lay.Simultaneously, required five classes when communication cable of the present utility model can meet the comprehensive wiring of wisdom building, the requirement that surpasses five classes, six classes, surpasses six class paired cables, frequency of utilization reaches as high as 600MHZ, exceeds the performance requirement 100MHZ of TIA/EIA568C.2 standard to such cable.Product appearance is rounded, can support the networks such as gigabit, ten thousand mbit ethernets, token-ring network, is applicable to indoor and outdoor and makes somebody a mere figurehead and pipeline wiring.
Although more than described preferred embodiment of the present utility model in detail, should be expressly understood that, for a person skilled in the art, the utility model can have various modifications and variations.All any modifications of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model within spirit of the present utility model and principle.
