Logical.For the ordinary skill in the art, can understand that above-mentioned term is at this by concrete condition
Concrete meaning in innovation and creation.
Describe the invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
A kind of braid shielded answering machine data transmission cable, as it is shown in figure 1, include that cross section is flat
Oversheath 7；Symmetrical it is provided with two lines to 1 described oversheath 7 is internal, and these two lines
1 interval is arranged；At described line to being provided with at least tear rope 8 between 1 and described oversheath 7,
Described tear rope 8 is close to described oversheath 7 and is arranged；Each described line all include 1 two mutually stranded
Insulated single wire 2 and the fire-retardant band 5 being coated with successively outside the two and woven shield 6；Insulated single wire 2
Insulating barrier 4 including the outside cladding of conductor 3 and conductor 3.It is pointed out that generally, tear rope
8 centered by two lines are to the midpoint of 1 line of centres, and symmetrical arranges two, so in oversheath 7
Both sides be designed with tear rope 8, can convenient construction time cable jacket stripping, improve work efficiency.
Wherein, described oversheath 7 is LSOH anti-flaming sheath, makes cable have high flame resistance, electricity
Cable safety coefficient is high.Described insulating barrier 4 is polyolefin insulation layer, has excellent insulating properties.
Wherein, described woven shield 6 uses copper wire or tinned copper wire braiding, and it weaves compactness >=85%,
And the copper wire used or the diameter >=0.1mm of tinned copper wire.Owing to woven shield 6 uses copper wire
Or tinned copper wire braiding forms, cable flexibility is good, and mechanical strength is high, and shield effectiveness is good.
Wherein, internal two the described lines of described oversheath 7 are to the twisting pitch of the insulated single wire 2 in 1 not
With.Typically, the twisting pitch of the insulated single wire 2 of internal two the described line centerings of oversheath 7 all≤300mm,
Reliable and stable to guarantee every electric property of cable.
This braid shielded answering machine data transmission cable manufacturing process is as follows:
First the insulated single wire 2 of two different colours carry out being made by twisting a line to 1, for ensureing cable
Every electric property stable, two lines should select different two pitch to carry out stranded to 1, and stranded
Pitch not should be greater than 300mm.
Stranded complete to line group outside use wrapped or vertical packet mode to be coated with one layer of fire-retardant band, then use
Weaving selects copper wire or tinned copper wire one layer of screen layer of braiding outside fire-retardant band.For guaranteeing cable
Shielding properties is excellent, selects the copper wire of braiding or tinned copper wire diameter should be not less than 0.1mm, and braiding is tight
Density should be not less than 85%.
Two lines braiding completed afterwards use actively unwrapping wire to 1, and keep two lines sequentially to arrange 1
Row, pass sequentially through winding displacement plate entrance extruding machine pancake core rod die sleeve and carry out extruding of oversheath 7, at symbol
On the premise of closing dimensions requirement, the THICKNESS CONTROL of oversheath 7 is at more than 1.8mm.
It should be noted that line is to before entering extrusion head, it is necessary to beat by tension disc control pair,
In order to avoid causing sheath bias and line to quality problems such as scratches.
The braid shielded answering machine data transmission cable that the invention is proposed, uses line to indulge 1 monolayer
To the mode of arrangement, increase line to spacing distance, be effectively increased product cross-talk performance indications,
Improving product propagation delay and propagation delay difference performance indications, its oversheath uses flat mode,
It is more suitable for indoor to lay, is particularly suitable for the installation at interior wall turning, railway signal building.
The foregoing is only the preferred embodiment of the invention, not in order to limit present invention wound
Make, within all spirit in the invention and principle, any modification, equivalent substitution and improvement made
Deng, within should be included in the protection domain of the invention.
