Abstract
The utility model relates to a data cable with independent branch shields, which comprises a conductor with an insulating layer, a main shield, and an external protective sleeve outside. The cable is formed by a plurality of pairs of core wires, wherein each pair of core wires is composed of two conductors which are separately coated with insulating layers and are twisted together. Each pair of core wires is coated with a branch shield, and each branch shield is coated with a plastic film which is printed with a mark. An earth wire is closely arranged between each pair of core wires and each independent branch shield, and each insulating layer of the conductors are a combined structure of foaming polyolefin and solid polyolefin. The utility model not only can improve the shielding effect of cables but also can distinguish different pairs of wires through the marked plastic films outside the core wires without distinguishing the colors of each pair of core wires. Thus the utility model saves materials and man-hours and lowers the manufacture cost of cables, and is characterized by better transmission performance, better mechanical strength, better voltage-resistance property, and better humidity-resistance property.
Description
Technical field
The utility model belongs to the data cable technical field, particularly relates to a kind of data cable that has independent branch shielding that is used for the carry high frequency data message.
Background technology
Rapid increase along with continuous expansion, extension and the transmission information amount of the fast development of mechanics of communication and computer network makes communication network and computer network increase progressively with bigger amplitude with the data cable consumption on the one hand; Require again on the other hand data cable to have higher transmission speed and better laser propagation effect, transmit fast and accurately with realization information.And the general real core polyolefin insulating structure of present known data cable, if have the independent shielding that divides, each between differentiation adopt the different insulative color mostly, especially big logarithm cable, the insulation color can be provided with a lot, this can be very loaded down with trivial details on making, waste material, and the as easy as rolling off a log hidden danger of quality that causes.
Summary of the invention
The utility model can change and improve cable insulation mechanical performance, withstand voltage properties and transmission performance for the technical problem that exists in the solution known technology provides, and saves simultaneously a kind of data cable with independent shielding of material.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Data cable with independent shielding, it comprises: conductor, conductor outside is provided with insulating barrier, always shielding and oversheath successively, it is characterized in that: described cable is many heart yearn to be made of, the every pair of heart yearn is to be covered with foaming by two conductor independent packets to add real core insulation layer and be twisted together and consist of, every pair of heart yearn outside all is coated with independent shielding, coat the plastic foil with sign in independent shielding outside, closely lay earth connection between the every pair of heart yearn and the independent shielding.
The utility model can also adopt following technical measures:
The independent shielding of every pair of heart yearn outside coating is aluminium-plastic tape.
The insulating barrier that described conductor independently coats is two kinds of colors.
Described cable also can not established total shielding and directly be coated with oversheath.
Sign on the described plastic foil is designed to digital code.
Sign on the described plastic foil also can be designed to alphanumeric codes.
Advantage and the good effect that the utlity model has are: because the utility model carries out independent shielding with every pair of heart yearn, and every pair of heart yearn shielding outside also coats one deck with the plastic foil of digital number.Have independent branch shielding and can promote the cable shield effect, and it is not collinear right to distinguish by the plastic film that has digital number outside shielding, and need not every pair of heart yearn color is distinguished one by one, so not only can save material and machining period, also can reduce manufacturing cost, the minimizing hidden danger of quality of cable.In addition, the insulating barrier of the utility model cable has also adopted expanded polyolefin and real core polyolefin combining form, therefore makes cable when improving transmission performance, has strengthened again mechanical strength, withstand voltage properties and the humidity resistance of insulating barrier.
Description of drawings
Fig. 1 is a cross-sectional structure schematic diagram of the present utility model;
Fig. 2 is the enlarged drawing of the utility model heart yearn.
Among the figure: 1. conductor; 2. foaming+real core insulation layer; 3. shield independent the branch; 4. tape identification plastic film; 5. earth connection; 6. polyester layer; 7. total shielding; 8. oversheath; 9. tear line.
Embodiment
In order further to understand summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, a kind of data cable with independent shielding, described cable is made of 8 pairs of heart yearns, the every pair of heart yearn is coated with respectively foaming+real core insulation layer 2 by two conductors 1 and twists together, described foaming adds that 2 on real core insulation layer is provided with two kinds of colors, and every pair of heart yearn outside all is coated with independent shielding 3.Independent shielding 3 in the present embodiment adopts aluminium-plastic tape, be coated with the plastic foil 4 with digital code or alphanumeric codes in independent shielding 3 outsides, can can distinguish different heart yearns by digital code or alphanumeric codes above the plastic foil 4 like this, and need not the heart yearn color of every centering is all distinguished.Closely be laid with independently earth connection 5 between the every pair of heart yearn and the independent shielding, electric charge on each screen layer metal surface is delivered in the earth smoothly by easy earthing mode to be gone, further improve the shield effectiveness of cable, guaranteed the transmitting of data message.8 pairs of heart yearns outside also is coated with polyester layer 6, always shields 7 and oversheath 8, is provided with tear line 9 in oversheath 8.In the present embodiment, described cable also can not established total shielding 7, and gets final product at polyester layer 6 outer direct coating oversheaths 8.
The heart yearn of the utility model cable is not limited to 8 pairs, also can change the logarithm of heart yearn according to actual needs.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
