Abstract
The utility model relates to a double-branch shielding data transmission cable which comprises two cable conductors. The two cable conductors are connected via a connecting rib. Each cable conductor is internally provided with four twisted wire pairs and a crossed support, wherein the four twisted wire pairs are separated from each other via the crossed support; and the cable conductor also comprises a polyester layer, a shielding layer and a protective layer, wherein the twisted wire pairs are successively wrapped in the polyester layer, the shielding layer and the protective layer, and the shielding layer is internally provided with a current-through conductor. A foaming polyethylene layer is used to greatly improve the transmission speed and reduce the delay inequality, thereby effectively avoiding loss of data packet in the data transmission process; the size of a copper core ranges from 0.540 to 0.550mm, the amount of copper conductor is greatly reduced, and thus, the cost is reduced; the parallel double-branch structure is used, namely eight twisted wire pairs are included, and two parallel cable conductors can be simultaneously protected and sleeved; and the data transmission cable equals at least two four-pair CAT6A FTP cable conductors when the cables are drawn and arranged in pipes onsite, so that the labor cost can be reduced, and convenience is provided for operation.
Description
Technical field
The utility model relates to a kind of data cable of two shieldings.
Background technology
The high speed development of 21 century data communication and information technology, driving the develop rapidly of whole wiring industry, higher requirement is not only proposed aspect transmission rate, also reducing costs, aspect proposes higher requirement, not only will propose to reduce in the manufacturing cost of product own, also in the application process in later stage, propose more convenient installation, more less manpower claims.I take charge of under such market background, in conjunction with the actual market demand, develop two shielding CAT6A FTP data cables.The most conductor of shielding CAT6A FTP product that existing market is used is bigger than normal, specification is 23AWG, stock size is 0.57～0.58mm, and the material of 4 pairs of insulation adopts is full-solid core structure or certain line to for some line of real core is to the structure for foaming, and is generally single 4 pairs of cables.The cost of product own is higher, and in wiring process, draws a cable at every turn, and installation and poling are all not too convenient.
Utility model content
The technical problems to be solved in the utility model is: for overcoming the problems referred to above, provide a kind of data cable of two shieldings.
The utility model solves the technical scheme that its technical problem adopts:
A kind of two shadow data transmission cables; comprise two cables; it is characterized in that; two described cables connect by dowel; in described cable, comprise 4 twisted pair wires, be also provided with cross frame in described cable, described cross frame separates 4 twisted pair wires respectively; described cable also comprises polyester layer, screen and the protective layer being wrapped in successively on described twisted pair wire, is also provided with percolation conductor in described screen.
Preferably, described twisted pair wire is by stranded formation of a pair of copper single line, and described copper single line comprises copper core and is coated on the polyethylene foamed layer outside copper core.
Preferably, described copper core diameter is 0.540-0.550mm.
Preferably, described screen adopts aluminium foil.
The beneficial effects of the utility model are: the utility model is simple in structure, thereby adopt polyethylene foamed layer greatly improve the speed of transmission and reduce delay inequality and effectively avoid data packet discarding in data transmission procedure, copper core is of a size of 0.540-0.550mm, greatly reduce the consumption of copper conductor, thereby reduce costs, cable adopts two parallel structures, and be 8 pairs of twisted pair wires, once just can go out two parallel cables by sheath, saved production cost, in the time of this novel bracing wire at the scene and poling, be to be once at least equivalent to the CAT6A FTP cable of 24 pairs, can both save cost of labor like this, facilitate again employee to operate.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the cutaway view of an embodiment of the utility model;
Mark in figure: 1-cable, 101-copper core, 102-polyethylene foamed layer, 103-twisted pair wire, 104-cross frame, 105-polyester layer, 106-percolation conductor, 107-screen, 108-protective layer, 109-dowel.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
Described in the utility model a kind of two shadow data transmission cables as shown in Figure 1; comprise two cables 1; two described cables 1 connect by dowel 109; in described cable 1, comprise 4 twisted pair wires 103; in described cable 1, be also provided with cross frame 104; described cross frame 104 separates 4 twisted pair wires 103 respectively; described cable 1 also comprises polyester layer 105, screen 107 and the protective layer 108 being wrapped in successively on described twisted pair wire 103, in described screen 107, is also provided with percolation conductor 106.
In preferred embodiments, described twisted pair wire 103 is by stranded formation of a pair of copper single line, and described copper single line comprises copper core 101 and is coated on the polyethylene foamed layer 102 outside copper core 101.In preferred embodiments, described copper core 101 diameters are 0.545-0.547mm.
Thereby adopt polyethylene foamed layer 102 greatly improve the speed of transmission and reduce delay inequality and effectively avoid data packet discarding in data transmission procedure, copper core 101 is of a size of 0.540-0.550mm, greatly reduce the consumption of copper conductor, thereby reduce costs, cable 1 adopts two parallel structures, and be 8 pairs of twisted pair wires 103, once just can go out two parallel cables by sheath, saved production cost, in the time of this novel bracing wire at the scene and poling, be to be once at least equivalent to the CAT6A FTP cable of 24 pairs, can both save cost of labor like this, facilitate again employee to operate.
In preferred embodiments, described screen 107 adopts aluminium foil.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to claim scope.
