Abstract
The utility model discloses a coaxial composite cable includes inner conductor, insulating layer, outer conductor and oversheath from inside to outside, the inner conductor adopt the configuration mode transposition of " 1+6 " to form by inner conductor conductive single wire, the outer conductor is formed with at least one control core combination after the winding by a plurality of outer conductor conductive single wire side by side again, the oversheath on still be equipped with the single line convex ridge, the single line convex ridge highly be not less than 0.5mm, the width is not less than 1mm. This cable wholly is full symmetrical structure, and copper wire and galvanized steel wire have blocking function, and inside and outside conductor is in concentric position, propagates in the medium in the electromagnetic energy confines to between the outer conductor, and it is little consequently to have a decay, and shielding property is high, compared with the prior art do not increase new additional strengthening, cable structure is simple, and the outside diameter of cable is less, conveniently lays. This cable not only light in weight, the decay little, the shielding effectual, can also play signal transmission and control action simultaneously.
Description
Technical field
This utility model relates to electric wire field, is specifically related to a kind of coaxial composite cable.
Background technology
World today's stepped into information epoch, information has become the strategic resource of economic development and unique production factors, combine the present information transmission system and complete information service system set up with multimedia terminals such as telecommunications network, computer, videos, it has also become the important symbol of a country economic development level.Coaxial cable is the important kind of one in information transmission, is mainly used as radio transmitting or feeder and various communication, the machine intraconnections of electronic equipment of the equipment of reception or is connected with each other line.
Chinese patent " ZL201520373236.X " discloses a kind of coaxial cable; its main contents are for increase enhancement Layer outside outer conductor; improve the tensile property that cable is overall to a certain extent; in laid processes; due to cable will through unwinding and rewinding around operating mode; and cable at this operating mode lower stress centrostigma at the bosom of cable point, central point is unprotected, and inner wire tensile property does not has been resolved;Owing to adding one layer or a few Rotating fields in cable, adding manufacturing procedure, reduce production efficiency, the weight of cable adds simultaneously, and on the one hand impact is installed, and on the other hand adds inner wire pressure in load bearing process, also has and does not have signal transfer functions.
Utility model content
In order to overcome the deficiencies in the prior art, it is provided that one is lightweight, it is little to decay, shield effectiveness good, signal transmission and the coaxial composite cable of control action can be simultaneously worked as.
For achieving the above object, the utility model discloses a kind of coaxial composite cable, include inner wire, insulating barrier, outer conductor and oversheath from inside to outside;Described inner wire is formed by the frame mode of inner wire conduction single line employing " 1+6 " is stranded;Outer conductor combines with at least control conductor after being wound around side by side by some outer conductor conduction single lines again;Being additionally provided with single line convex ridge on described oversheath, the height of described single line convex ridge is not less than 0.5mm, and width is not less than 1mm.
Preferably, described control conductor is by controlling conductor and being extruded in the control insulating barrier controlled outside conductor and constitute.
Preferably, described inner wire conduction single line is annealing copper wire with outer conductor conduction single line, annealing copper wire is the naked annealed copper conductor meeting GB/T3956-2008 or metal cladding annealed copper conductor that cable is conventional, the conductor formed including the hard circular copper wire of multiply of compacting pressing or the conductor of the non-multiply pressed soft circular copper wire composition, preferential selection 5 class zinc-plated soft structure conductor.
Preferably, described insulating barrier is made up of Low Density Polyethylene, high density polyethylene (HDPE) or radiant crosslinked polyethylene material.
Preferably, described oversheath is made up of polythene material.
The beneficial effects of the utility model are:
This utility model is provided with control conductor in conductor, can simultaneously work as signal transmission and control action;Cable entirety is full symmetrical configuration, and copper wire and zinc-coated wire have function of shielding, and inner and outer conductor is in concentric position, and electromagnetic energy is confined to the media between internal and external conductor, therefore has decay little, and shielding properties is high;Compared with prior art not increasing new reinforcement structure, the construction of cable is simple, and the outside diameter of cable is less, conveniently lays.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with this utility model, it should be understood that these embodiments are merely to illustrate this utility model rather than limit scope of the present utility model, after having read this utility model, those skilled in the art all fall within the application claims limited range to the amendment of the various equivalent form of values of the present utility model.
As it is shown in figure 1, this utility model provides a kind of coaxial composite cable, include inner wire, insulating barrier 2, outer conductor and oversheath 4 from inside to outside;It essentially consists in, and described inner wire is used by inner wire conduction single line 1 that the frame mode of " 1+6 " is stranded to be formed;Outer conductor combines with two control conductor after being wound around side by side by some outer conductor conduction single lines 3 again, and pitch controls between 75-105mm, and winding direction is left-hand;Described control conductor is by controlling conductor 5 and being extruded in the control insulating barrier 6 controlled outside conductor and constitute;Being additionally provided with single line convex ridge 7 on described oversheath 4, the height of described single line convex ridge 7 is not less than 0.5mm, and width is not less than 1mm.
Described inner wire conduction single line is annealing copper wire with outer conductor conduction single line, annealing copper wire is the naked annealed copper conductor meeting GB/T3956-2008 or metal cladding annealed copper conductor that cable is conventional, the conductor formed including the hard circular copper wire of multiply of compacting pressing or the conductor of the non-multiply pressed soft circular copper wire composition, preferential selection 5 class zinc-plated soft structure conductor.
This cable entirety is full symmetrical configuration, and copper wire and zinc-coated wire have function of shielding, and inner and outer conductor is in concentric position, and electromagnetic energy is confined to the media between internal and external conductor, therefore has decay little, and shielding properties is high;And in outer conductor, set up control conductor, signal transmission and control action can be simultaneously worked as;Compared with prior art not increasing new reinforcement structure, the construction of cable is simple, and the outside diameter of cable is less, conveniently lays.
The above is only preferred implementation of the present utility model; it should be pointed out that, for the person of ordinary skill of the art, on the premise of without departing from this utility model principle; can also make some modification and improvement, these also should be regarded as belonging to protection domain of the present utility model.
