Abstract
The utility model discloses a reinforced data cable comprising wires, a filling skeleton, and an over sheath wrapped round the wires and the filling skeleton. Four cavities are formed by the cross-shaped filling skeleton and the over sheath. Every two wires are mutually twisted to become a twisted pair wire. The twisted pair wires are placed in the four cavities and the number of the twisted pair wires in a cavity is the same as those in the others. A reinforcing steel wire is disposed at the center of the cross-shaped filling skeleton. By above manner, tensile strength of the data cable is enhanced while the data cable has little integral diameter and light weight. In addition, a phenomenon of crosstalk between adjacent wires in signal transmission is prevented.
Description
Technical field:
The utility model relates to communication technique field, is specifically related to reinforced data cable.
Background technology:
Data communication line is widely used in communication technique field, and communication has important impact to its performance on data.General cable is often because the product overall tensile strength is inadequate, and appearance is easily broken, the situation of yielding drawing-down, various reinforced data cables occur for this situation.Common reinforced data cable is coated with plastic insulating layer for improving hot strength and the anti-wear performance of cable at cable core on the market, and plastic layer is outward sheath, and sheath has the layer of metal armour outward, outer jacket clad metal armour.Because plastic insulating layer and metal armouring layer are thicker, cause reinforced data cable diameter thicker, and weight are large, be difficult for carrying and installation.And because the cable core wire is mutually close in the cable, be prone to cross-talk in transmission signal process, poor TV signal is clear.
The utility model content:
The purpose of this utility model is for above-mentioned deficiency of the prior art, provide a kind of hot strength higher, and the cable integral diameter is less, the reinforced data cable of weight saving, and this data cable has also been avoided the phenomenon of adjacent wires easy cross-talk in the signal transmission.
For achieving the above object, the technical scheme that the utility model provides is: a kind of reinforced data cable, the oversheath that comprises wire, filling skeleton and coated wire and filling skeleton, wherein, described filling skeleton is cruciform skeleton, and described cruciform skeleton and oversheath form 4 cavitys, and described wire twists into mutually one group of twisted pair wire pair in twos, described twisted pair wire is to equal in number placing in described 4 cavitys, and the center of described cruciform skeleton is provided with one and strengthens steel wire.
Preferably, described reinforcement steel wire adopts zinc-coated wire.
Further, described jacket material is polyvinyl chloride or polyethylene.
By above-mentioned technological means, the beneficial effect that the utility model is realized is: the data cable diameter is less, weight saving, and tensile strength is higher, and has avoided the cross-talk phenomenon of wire in signals transmission.
Description of drawings:
Fig. 1 is the structural representation of the utility model one preferred embodiment;
Each parts mark is as follows among the figure: the 1-oversheath, and 2-twisted pair wire pair, the 21-wire, the 3-cruciform skeleton, 4-strengthens steel wire, 5-the first cavity, 6-the second cavity, 7-the 3rd cavity, 8-the 4th cavity.
Embodiment:
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection range of the present utility model is made more explicit defining.
Please refer to accompanying drawing 1, a kind of reinforced data cable comprises wire 21, cruciform skeleton 3 and oversheath 1, wherein, and oversheath 1 coated wire 21 and cruciform skeleton 3.Cruciform skeleton 3 forms four cavitys with oversheath 1, is respectively: the first cavity 5, the second cavity 6, the 3rd cavity 7 and the 4th cavity 8.Wire 21 is totally 8 in the present embodiment, and per two wires 21 twist into mutually one group of twisted pair wire to 2, obtains altogether four groups of twisted pair wires to 2.Four groups of twisted pair wires place respectively in four cavitys 2, because the interval of cruciform skeleton 3 being arranged, in the data-signal transmission course, each twisted pair wire cross-talk can not occur between 2.The center of cruciform skeleton 3 is provided with one and strengthens steel wire 4, what this reinforcement steel wire 4 adopted is zinc-coated wire, be used for strengthening the tensile strength of whole cable, in addition, because the adding of zinc-coated wire, so that cross skeleton 3 overall dimensions increase, thereby strengthened four groups of twisted pair wires to 2 physical separation, the transmission performance of cable is improved.
In the present embodiment, cruciform skeleton 3 adopts polythene material to make, and can also take polyvinyl chloride or low smoke and zero halogen material to make according to actual conditions.
Oversheath 1 adopts pvc material to make in the present embodiment, and its effect is to protect whole cable, in order to avoid the cable wearing and tearing.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
Claims (3)
