Abstract
The utility model discloses a communication transmission cable. The communication transmission cable comprises internal conductors and an external protective structure; the internal conductors comprises three signal lines, each signal line comprises a copper core, a first shielding layer, a foaming layer and an insulating layer, the first shielding layer, the foaming layer and the insulating layer are successively arranged outside the copper core, and the outer diameter of each signal line is 2mm to 2.8mm; the external protective structure is arranged outside the internal conductors, the external protective structure successively comprises an inner protecting layer, an armored layer, a second shielding layer and an outer protecting layer; and the outer diameter of the communication transmission cable is between 10mm and 10.8mm. The utility model provides the communication transmission cable which has a good shielding effect and prevents aging.
Description
Technical field
The utility model relates to a kind of communication transmission cable.
Background technology
Communication transmission cable extensive use and electric power, communications, along with the development of technology, the occasion that need to use cable is more and more, and, there is the poor problem of shield effectiveness in the communication transmission cable of prior art.
Utility model content
The purpose of this utility model be to provide a kind of shield effectiveness good, prevent aging communication transmission cable.
To achieve these goals, the technical scheme that the utility model provides is: a kind of communication transmission cable is provided, it comprises: inner conductor and exterior protection structure, described inner conductor comprises three holding wires, every holding wire comprises: copper core and be also disposed with the first screen, foaming layer and insulating barrier in copper core outside, and the external diameter of every holding wire is 2～2.8 millimeters; Described exterior protection structure is arranged on outside described inner conductor, comprises successively sheath, armour, secondary shielding layer and outer jacket, and the external diameter of described communication transmission cable is between 10～10.8 millimeters.
Compared with prior art, the utility model be a kind of shield effectiveness good, prevent aging communication transmission cable.
By following description also by reference to the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used for explaining embodiment of the present utility model.
Brief description of the drawings
Fig. 1 is the schematic cross-section of the utility model communication transmission cable.
Embodiment
With reference now to accompanying drawing, describe embodiment of the present utility model, in accompanying drawing, similarly element numbers represents similar element.As mentioned above, as shown in Figure 1, the communication transmission cable 100 that the utility model provides, comprise: inner conductor and exterior protection structure 20, described inner conductor comprises three holding wires 10, every holding wire 10 comprises: copper core 1 and be also disposed with the first screen 2, foaming layer 3 and insulating barrier 4 in copper core 1 outside, and the external diameter of every holding wire 10 is 2～2.8 millimeters; Described exterior protection structure 20 is arranged on outside described inner conductor, comprises successively sheath 5, armour 6, secondary shielding layer 7 and outer jacket 8, and the external diameter of described communication transmission cable 100 is between 10～10.8 millimeters.
In conjunction with Fig. 1, because the utility model communication transmission cable 100 includes the first screen 2 and and therefore screen 7 can improve shield effectiveness, the utility model be a kind of shield effectiveness good, prevent aging communication transmission cable.
Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
