Abstract
The utility model relates to a comprehensive cable for digital communication, belonging to the technology of communication cables. The comprehensive cable for digital communication which is mainly used for the wire laying of buildings or building groups with broadband digital communication networks is composed of a coaxial tube and five classes of wire pairs. The coaxial tube is positioned at the center of the comprehensive cable, and the five classes of wire pairs are distributed uniformly at the periphery of the coaxial tube according to a concentric circle; filling materials can be arranged between the five classes of wire pairs when the cable is formed in order to force a cable core to be round. The coaxial tube is provided with an independent jacket, and the periphery of the five classes of wire pairs is also provided with a jacket. The comprehensive cable provided by the utility model organically combines a radio-frequency coaxial cable connected to a network and a pair strand symmetrical cable together, provides convenience for the laying of the communications network of buildings, and saves laying space, which is convenient for the reformation of communication line and is adapted to the development from a narrow band communication network to broadband communication network.
Description
It is a kind of digital communication comprehensive cable that the utility model relates to, and belongs to communications cable technology, is mainly used in the wiring of the building or the buildings of wideband digital communication network.
Building or buildings are used for the wiring of wideband digital communication network at present, and the Access Network radio frequency coaxial-cable of use and digital communication are two independently cables with the mutual-hinge line symmetrical cable.These two kinds of cables will lay respectively in building.Because the roughing-in bore does not wait, and construction is made troubles; The communication network of while in building laid very disorderly, do not meet the requirement of construction and decoration, time-consuming taking a lot of work.
The purpose of this utility model provides a kind of digital communication comprehensive cable, and it organically constitutes one to Access Network radio frequency coaxial-cable and digital communication with the mutual-hinge line symmetrical cable, and the communication network in the building is laid conveniently, saves and lays the space.
The purpose of this utility model is achieved in that a kind of digital communication comprehensive cable, and it to forming, is characterized in that coaxitron is positioned at the center of comprehensive cable by coaxitron and 5 class lines, and 5 class lines are to being distributed on the periphery of coaxitron by concentric circles.For making the cable core rounding, stranding can 5 class lines between be provided with filler.Coaxitron has independently sheath, and also there is sheath the right periphery of 5 class lines.
Digital communication is with there being a coaxitron in the comprehensive cable, 5 class lines can be 2,4,6,8,10,15,16,20,25 to configuration quantity.
Accompanying drawing is a structural representation of the present utility model.
In conjunction with the accompanying drawings structure of the present utility model is illustrated:
A kind of digital communication comprehensive cable, it is made up of 2 coaxitron 1 and 5 class lines, and its coaxitron 1 is positioned at the center of comprehensive cable, and it is an independently Access Network radio frequency coaxial-cable.It is made of coaxitron 1 outer conductor of the inner wire of copper covered steel wire or copper cash and physics highly foaming polyethylene insulating barrier and aluminum-plastic composite membrane 1 knit wire.It has independent sheath 3 coaxitron 1, and sheath 3 is the inner sheaths that are made of comprehensive cable the PVC plastic.The key property of coaxitron is: characteristic impedance=75 ± 3 Ω, frequency of utilization scope are 5MHz-1.32GHz SRL＞20db (in the 5MHz-1.3GHz scope).
5 class lines are distributed on the periphery of coaxitron 1 to 2 by concentric circles, and it is a digital communication mutual-hinge line symmetrical cable, and its quantity can be 2,4,6,8,10,15,16,20,25.5 class lines are to being to be made of the conductor of bare copper wire or silver-coated copper wire and high density polyethylene (HDPE) solid or skin-foam-skin structure (HDPE) insulating barrier.5 class lines also have filler between 2, be used to guarantee the shaped of comprehensive cable core.The outer sheath 5 that is with that 5 class lines are right, sheath 5 are oversheaths that PVC or polyethylene (PE) constitute comprehensive cable.The right key property of 5 class lines is: physical impedance 100 ± 15 Ω, the frequency of utilization scope is 0-100MHz, the decay under 100MHz: 22dB, max, SRL 16dB, min, (under the 100MHz).
The digital communication comprehensive cable that the utility model provides, it organically constitutes one to Access Network radio frequency coaxial-cable and digital communication with the mutual-hinge line symmetrical cable.The key property of comprehensive cable depends on coaxitron and the right performance of 5 class lines, and physical and mechanical properties is fit to environment for use and user's requirement.It can make communication network in the building lay convenience is provided, and has saved the laying space, and transformation that can convenient communication line also is adapted to develop to broadband communication network with the narrowband communications networks that has.
Claims (5)
