Abstract

The utility model relates to a communication and electrical control comprehensive signal cable, which comprises coaxial transmission lines, a shielding line set and a jacket, wherein the two coaxial transmission line and the shielding line set are stranded into a bundle and then are extruded with a layer of jacket. The signal cable has the benefits that: 1. the attenuation of the coaxial transmission lines can be small: the physical foamed polyethylene can greatly reduce the dielectric constant of material, so that the attenuation of signals can be small when in transmission; 2. the weight is light: the structural size is greatly reduced, so as to reduce the weight of the product; 3. the integrity is high: due to the combined form of a plurality of units, the overall structure is compact, and the integration is high; 4. the shielding is good: by adopting anaerobic cooper lines for multi-strand weaving, the coverage density is big, the anti-jamming capability is strong, and the shielding effect is good; 5. the flexibility is good: a three-core shielding set adopts multi-strand refined-twisting anaerobic cooper, therefore, the flexibility is good; the outer jacket adopts the flexible PVC, thereby improving the integral flexibility and being suitable for the small-radius bending connection; and 6. the stability is good: the outer jacket is tightly extruded, therefore, the product has stable electrical property and rounding and stable structure.

Description

Communication and electrical control integrated signal cable
Technical field
The utility model relates to a kind of cable, and particularly a kind of modern office place is used for the communication and the electrical control integrated signal cable of composite signal transmission usefulness.
Background technology
Develop rapidly along with national economy, the comprehensive wiring that communication and electric signal are transmitted simultaneously requires to get more and more. and the cable that uses is proposed more and more higher requirement, and cable develops to miniaturization, integrated, in light weight, directions such as shielding is good, transmission objective height.General communication coaxial transmission line is an insulating material with solid polyethylene, cable dimension is relatively big, and frequency range is narrow, signal attenuation index instability, be arranged together mutual electromagnetic with the electric signal transmission line and disturb greatly, can not satisfy the communicating requirement of modern office.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of and need connect simultaneously and with electric signal in the multichannel high-frequency signal transmission, closely and not is subjected to the communication and the electrical control integrated signal cable of the other side and external interference each other in the space wiring.
The utility model for achieving the above object, the technical scheme that is adopted is: a kind of communication and electrical control integrated signal cable, it is characterized in that: comprise coaxial transmission line, shielding conductor group, sheath, two described coaxial transmission lines, the stranded bunchy of shielding conductor group extrude one deck sheath again.
The beneficial effects of the utility model are: 1, the coaxial transmission line attenuation is little: the physical blowing polyethylene is as insulating layer material, and this kind air can lower the dielectric constant of material greatly, makes signal decay when transmission little.2, in light weight: as to have adopted the wrapped material of polyester film with sheath shaft, thereby reduced the weight that physical dimension alleviates product greatly.3, integrated height: adopted a plurality of unit combination forms, made compact overall structure, integrated height.4, shielding is good: adopt the braiding of anaerobic copper cash multiply, coverage density is big, and antijamming capability is strong, and shield effectiveness is good.5, flexibility is good: the three-core shielding group adopts the smart strand of multiply oxygen-free copper, and flexibility is good, and oversheath adopts soft PVC to increase overall bulk softness, is fit to be connected with minor radius is crooked.6, stability: closely extrude oversheath, make the product electric performance stablity, the structure rounding is stable.
Description of drawings
Fig. 1 is a structural representation of the present utility model and as Figure of abstract.
Embodiment
As shown in Figure 1, communication and electrical control integrated signal cable comprise coaxial transmission line 1, shielding conductor group 2, sheath 3, and shielding conductor group 2 stranded bunchys extrude one deck sheath 3 outside it.Coaxial transmission line 1 comprises, extrudes one deck foaming insulation layer 1-2, braiding one deck annealing anaerobic copper cash braid successively as outer conductor 1-3, wrapped one deck polyester film 1-4 outside inner wire 1-1.Sheath 3 is soft pvc material.Shielding conductor group 2 comprises control core 2-1, polyester film 2-3 outer conductor 2-4, described control core 2-1 extrudes one deck PVC insulating barrier 2-1-2 outward by inner wire 2-1-1 and constitutes, the three wrapped successively outward one deck polyester film 2-3 of control core 2-1, braiding one deck outer conductor 2-4.The insulating barrier 1-2 that fires is the physical blowing polythene material.Outer conductor 1-3 is annealing anaerobic copper cash braid.Outer conductor 2-4 is annealing anaerobic copper cash braid.
The utility model can obtain by following technical process manufacturing: extrude foaming insulation layer 1-2 at solid coaxial inner conductor 1-1 external application cable extrusion foaming equipment, at foaming insulation layer 1-2 external application braiding machine braiding one deck outer conductor 1-3, wrapped polyester film 1-4 outside outer conductor 1-3 constitutes coaxial transmission line 1 with wrapped equipment.Be inner wire 2-1-1 with electric wire cable strand machine or the stranded multiply anaerobic of bunching machine copper cash, outside multiply inner wire 2-1-1, extrude one deck PVC insulating barrier 2-1-2 with the cable extrusion equipment and constitute control core 2-1,3 control core 2-1 are twisted together with stranded cable equipment by color sequences, use the wrapped polyester film 2-3 of wrapped equipment simultaneously, outside polyester film 2-3, weave one deck annealing anaerobic copper cash outer conductor 2-4 with braiding apparatus and constitute shielding conductor group 2, with cabler two coaxial transmission lines 1, a shielding conductor group 2 twists together, and extrudes the PVC soft elastomer as sheath 3 at its external application extrusion equipment then.
