Abstract
The invention relates to an industrial network cable, in particular to a special communication double-layer shielding cable for the industrial network. The special communication double-layer shielding cable comprises an outer sheath, in which an insulating core quad is arranged; the insulating core quad consists of a red insulating core wire, a black insulating core wire, a yellow insulating core wire and a blue insulating core wire; the red insulating core wire is stranded with the black insulating core wire to form a red-black core quad; the yellow insulating core wire is stranded with the blue insulating core wire to form a yellow-blue core quad; the red-black core quad is stranded with the yellow-blue core quad; and a shielding layer is arranged between the inner side of the outer sheath and the insulating core quad. The special communication double-layer shielding cable is characterized by high transmission performance and strong external interference resisting capability, which meets the high requirement on the cable signal transmission in the industrial network, and ensures that the signal can be transmitted successfully even if the inner interference of the cable per se is reduced to the lowest value; and meanwhile, the special communication double-layer shielding cable removes the shielding of the external interference signal so that the signal transmission does not distort.
Description
Technical field
The present invention relates to a kind of industrial network cable, refer more particularly to the special-purpose communication double layer screen of a kind of industrial network cable.
Background technology
More and more higher to the requirement of industrial network cable signal transmission at present, existing cable can not satisfy high request fully.Can influence the smooth transmission of signal mainly due to the internal interference of cable self, existing industrial network cable is not very strong to the shielding action of external interference signals simultaneously yet, causes using the signal transmission to have distortion phenomenon at last.
Based on the weak point of above-mentioned existing industrial network cable, the inventor has developed the present invention's a kind of " the special-purpose communication double layer screen of industrial network cable ".
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art technical problem to be solved is: the special-purpose communication double layer screen of a kind of industrial network cable is provided.
The technical solution adopted for the present invention to solve the technical problems is:
The special-purpose communication double layer screen of a kind of industrial network cable, comprise oversheath, be provided with insulation heart yearn group in the described oversheath, insulation heart yearn group is made up of a red insulation heart yearn, black insulation heart yearn, a yellow insulation heart yearn and a blue insulation heart yearn, red insulation heart yearn becomes red-black heart yearn group with black insulation heart yearn pair twist, yellow insulation heart yearn becomes champac heart yearn group with blue insulation heart yearn pair twist, red-black heart yearn group and champac heart yearn group are closed strand, are provided with screen between oversheath inboard and the insulation heart yearn group.
The lay of described red insulation heart yearn and black insulation heart yearn is 28mm, and the lay of yellow insulation heart yearn and blue insulation heart yearn is 32mm, and the lay of red-black heart yearn group and champac heart yearn group is 87mm.The external diameter of insulation heart yearn is 2.0mm ± 0.05mm.
Described red insulation heart yearn, black insulation heart yearn, yellow insulation heart yearn and blue insulation heart yearn area of section are 0.5cm
2
Described red insulation heart yearn, black insulation heart yearn, yellow insulation heart yearn and blue insulation heart yearn are formed by the thin copper wire bundle strand that diameter is not more than 0.16mm.
Described screen is aluminium foil and tinned copper wire woven shield.The width of aluminium foil and tinned copper wire woven shield is 22mm, has guaranteed that holder bag is can envelope 4 heart yearns entirely and not overlapping base is risen, and copper wire adopts the tinned copper wire braiding of 128 0.1mm to form.
Described total heart yearn outside is provided with aluminium foil and tinned copper wire woven shield, and the external diameter of oversheath is at 7.8mm ± 0.1mm.
The beneficial effect of the special-purpose communication double layer screen of a kind of industrial network of the present invention cable is:
Good, the anti-external disturbance ability of transmission performance is strong, has satisfied the high request of industrial network cable signal transmission, and it is best that the internal interference of cable self was dropped to, and makes the signal to transmit smoothly; Solved simultaneously the shielding action to external interference signals, using signal to transmit can distortion yet.

Embodiment
Below in conjunction with embodiment the special-purpose communication double layer screen of a kind of industrial network cable that the technical program provides is described further.
The present invention implements like this:
In Fig. 1 and Fig. 2, the special-purpose communication double layer screen of a kind of industrial network cable, comprise oversheath 70, be provided with insulation heart yearn group in the oversheath 70, insulation heart yearn group is made up of a red insulation heart yearn 20, black insulation heart yearn 30, one yellow insulation heart yearn 40 and a blue insulation heart yearn 50, red insulation heart yearn 20 is twisted into red-black heart yearn group with 30 pairs of heart yearns of black insulation, yellow insulation heart yearn 40 and blue 50 pairs of heart yearns of insulation are twisted into champac heart yearn group, red-black heart yearn group and champac heart yearn group are closed strand, are provided with screen 60 between oversheath 70 inboards and the insulation heart yearn group.
In the present embodiment, red insulation heart yearn 20 is 28mm with the lay of black insulation heart yearn 30, and the lay of yellow insulation heart yearn 40 and blue insulation heart yearn 50 is 32mm, and the lay of red-black heart yearn group and champac heart yearn group is 87mm.Red insulation heart yearn 20, black insulation heart yearn 30, yellow insulation heart yearn 40 and blue insulation heart yearn 50 areas of section are 0.5cm
2Red insulation heart yearn 20, black insulation heart yearn 30, yellow insulation heart yearn 40 and blue insulation heart yearn 50 are formed by the thin copper wire bundle strand that diameter is not more than 0.16mm.Screen 60 is aluminium foil and tinned copper wire woven shield.
