Abstract
The utility model is suitable for data transmission cable technical field.The utility model discloses a kind of data transmission cables, including crust (1), two-wire group (2), it is characterized in that, the two-wire group (2) is composed of two core wires (20), two core wires (20) are externally provided with combination layer (23), and core wire (20) is equipped with conducting wire (21), core wire crust (22)；Array two-wire group (2) is gathered, and section wraps up into circle, then by crust (1), and crust (1) section is circle, and appearance is no stock line and smooth；The beneficial effects of the utility model are：Data line is with traditional ratio, and using smooth in appearance without stock line, easily control is in more than 9db for return loss surplus, into two-wire group structure design so that data transmission cable electrical characteristic is more preferable.
Description
Technical field
The utility model is related to data transmission cable technical field, more particularly to a kind of data transmission cable.
Background technology
Twisted-pair feeder in computer LAN can be divided into unshielded twisted pair (UTP) and Shielded Twisted Pair (STP) two is big
Class：UTP is wrapped up in without metal shield materials, only one layer of insulating cement suitcase, and price is relatively cheap, networking flexibility.By one layer outside STP
Metal material wraps up, and to reduce radiation, information is prevented to be ravesdropping.There is higher message transmission rate, but higher price simultaneously,
Installation is also more complicated.We use UTP under normal circumstances.The UTP used now can be divided into five classes, surpass five classes, six classes, surpass
Six classes.Wherein five class UTP become the preferred medium of Fast Ethernet (100Mbps) when of high quality and at a reasonable price；Surpass useing force for five class UTP
Ground be Gigabit Ethernet (1000Mbps).
At present, in existing data line cable, crust surface all has line shape, and electrical characteristic requirement is
General standard.So need to break tradition, and a kind of better data transmission cable of electrical characteristic.
Utility model content
The utility model is mainly solving the technical problems that provide a kind of multicore shielding cable, a kind of data line
Cable, breaking traditional appearance has a strand line, and electrical characteristic is more preferable.
To solve the above-mentioned problems, the utility model provides a kind of data transmission cable, described including crust, two-wire group
Two-wire group is composed of two core wires, and two core wires are externally provided with combination layer, and core wire is equipped with conducting wire, core wire crust；Array two-wire
Group set, section wraps up into circle, then by crust, and the crust section is circle, and appearance is no stock line and smooth.
Furtherly, the conducting wire reaches more than 95% using quiet dynamic bimodulus combination twisted wire technology, stranded conductor out of roundness,
Single open traverse resistivity control is within ± 3%.
Furtherly, the crust is semi-rigid PVC material, using the fixed pipe extrusion process of semi-rigid PVC.
Furtherly, the two-wire group in a kind of data transmission cable, can be four groups.
In use, since two-wire group is composed of two core wires, crust section is circle, and appearance is no stock line and light
It is sliding；Conducting wire reaches more than 95% using quiet dynamic bimodulus combination twisted wire technology, stranded conductor out of roundness, single open traverse resistivity control
System is within ± 3%, so electrical characteristic is more preferable.
The beneficial effects of the utility model are：Data line is with traditional ratio, using smooth in appearance without stock line, echo damage
Consuming surplus, easily control is in more than 9db, into two-wire group structure design so that data transmission cable electrical characteristic is more preferable.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, and the attached drawing in describing is this practicality
Some novel embodiments, to those skilled in the art, without creative efforts, can be with
Other accompanying drawings are obtained according to these attached drawings.
Fig. 1 is the diagrammatic cross-section of the utility model cable.
With reference to embodiment, and with reference to attached drawing, the realization of the utility model aim, functional characteristics and advantage are made into one
Walk explanation.
Specific embodiment
In order to make the purpose, technical scheme and advantage of utility model clearer, implement below in conjunction with the utility model
Attached drawing in example, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described reality
It is utility model part of the embodiment to apply example, instead of all the embodiments.Based on the embodiment in the utility model, this field
It is new to belong to this practicality for those of ordinary skill's all other embodiments obtained under the premise of creative work is not made
The range of type protection.
Embodiment one
Refering to shown in attached drawing 1, a kind of data transmission cable, including crust 1, two-wire group 2, which is characterized in that described
Two-wire group 2 is composed of two core wires 20, and two core wires 20 are externally provided with combination layer 23, and core wire 20 is equipped with conducting wire 21, outside core wire
Skin 22；Array two-wire group 2 is gathered, and section is wrapped up into circle, then by crust 1, and 1 section of crust is circle, and outer
Table is no stock line and smooth.
Specifically：Since two-wire group 2 is composed of two core wires 20,1 section of crust is circle, and appearance is no stock line
It is and smooth；Conducting wire 21 reaches more than 95% using quiet dynamic bimodulus combination twisted wire technology, 21 out of roundness of stranded conductor, single open traverse
21 resistivity are controlled within ± 3%, so electrical characteristic is more preferable.
Refering to shown in attached drawing 1, the conducting wire 21 is reached using quiet dynamic bimodulus combination twisted wire technology, 21 out of roundness of stranded conductor
To more than 95%, single 21 resistivity of open traverse control is within ± 3%.
Refering to shown in attached drawing 1, the crust 1 is semi-rigid PVC material, using the fixed pipe extrusion process of semi-rigid PVC.
Refering to shown in attached drawing 1, the two-wire group 2 in a kind of data transmission cable can be four groups.
Above example is only to illustrate the technical solution of the utility model, rather than its limitations；Although with reference to aforementioned reality
Example is applied the utility model is described in detail, it will be understood by those of ordinary skill in the art that：It still can be to preceding
The technical solution recorded in each embodiment is stated to modify or to which part technical characteristic progress equivalent replacement, and these
Modifications or substitutions, the spirit and model of various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution
It encloses.
