Abstract
The invention discloses a coaxial composite cable. The coaxial composite cable comprises an inner conductor, an insulating layer, an outer conductor and an outer sheath from the inner side to the outer side; the inner conductor is formed by intertwisting inner conductor conductive single lines in a ''1+6'' structure; the outer conductor is formed by winding a plurality of outer conductor conductive single lines in parallel and then combining the outer conductor conductive single lines with at least one control wire core; the outer sheath is further provided with a single line convex ridge; and the height of the single line convex ridge is not less than 0.5 mm and the width of the single line convex ridge is not less than 1 mm. The overall cable is in a full-symmetrical structure; copper wires and zinc plated steel wires have a shielding function; the inner conductor and the outer conductor are in the concentric position; the electromagnetic energy is defined in the medium between the inner conductor and the outer conductor for propagation, so that the cable is low in attenuation and good in shielding property; compared with the prior art, no new reinforcing structure is added; the cable is simple in structure, small in outer diameter, convenient to lay, light in weight, low in attenuation, good in shielding effect, and capable of realizing signal transmission and signal control at the same time.
Description
Technical field
The present invention relates to electric wire field, be specifically related to a kind of coaxial composite cable.
Background technology
The world today is the stepped into information epoch, information has become the strategic resource of economic development and unique production factors, to combine the present information transmission system and complete information service system set up with multimedia terminals such as telecommunications network, computer, videos, become the important symbol of a country economic development level.Coaxial cable is the important kind of one in information transmission, main be used as radio transmission or receiving equipment feeder and various communication, electronic equipment machine intraconnections or be interconnected line.
Chinese patent " ZL201520373236.X " discloses a kind of coaxial cable, its main contents are for increase reinforced layer outward at outer conductor, improve the tensile property of whole cable 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 protected, and inner wire tensile property is not resolved; Owing to adding one deck or a few Rotating fields in cable, add manufacturing procedure, reduce production efficiency, the weight of cable adds simultaneously, affect installation on the one hand, add the pressure of inner wire in load bearing process on the other hand, not there is signal transfer functions in addition.
Summary of the invention
In order to overcome the deficiencies in the prior art, provide a kind of lightweight, decay little, shield effectiveness good, can play the coaxial composite cable of signal transmission and control action simultaneously.
For achieving the above object, the invention discloses a kind of coaxial composite cable, comprise inner wire, insulating barrier, outer conductor and oversheath from inside to outside; Described inner wire forms by the frame mode of inner wire conduction single line employing " 1+6 " is stranded; Outer conductor is conducted electricity after single line is wound around side by side by some outer conductors and combines with at least one control conductor; Described oversheath is also provided with single line convex ridge, and 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 be extruded in the control insulating barrier controlled outside conductor to form.
Preferably, described inner wire conduction single line and outer conductor conduct electricity single line and are annealing copper wire, annealing copper wire is the naked annealed copper conductor meeting GB/T3956-2008 commonly used of cable or metal cladding annealed copper conductor, comprise the conductor of the multiply hard circular copper wire composition of compacting pressing or the conductor of the soft circular copper wire composition of non-multiply of pressing, preferentially select the zinc-plated soft structure conductor of 5 class.
Preferably, described insulating barrier is made up of low density polyethylene (LDPE), high density polyethylene (HDPE) or radiant crosslinked polyethylene material.
Preferably, described outer jacket is made up of polythene material.
Beneficial effect of the present invention is:
The present invention is provided with control conductor in conductor, can play signal transmission and control action simultaneously; Whole cable 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 propagate in the medium between internal and external conductor, and therefore have decay little, shielding properties is high; Compared with prior art do not increase 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 invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims limited range.
As shown in Figure 1, the invention provides a kind of coaxial composite cable, comprise inner wire, insulating barrier 2, outer conductor and oversheath 4 from inside to outside; It is mainly, described inner wire conducts electricity single line 1 by inner wire and adopts that the frame mode of " 1+6 " is stranded to be formed; Outer conductor is conducted electricity after single line 3 is wound around side by side by some outer conductors and combines with two control conductor, and pitch controls between 75-105mm, and winding direction is left-hand; Described control conductor is by controlling conductor 5 and be extruded in the control insulating barrier 6 controlled outside conductor to form; Described oversheath 4 is also provided with single line convex ridge 7, and 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 and outer conductor conduct electricity single line and are annealing copper wire, annealing copper wire is the naked annealed copper conductor meeting GB/T3956-2008 commonly used of cable or metal cladding annealed copper conductor, comprise the conductor of the multiply hard circular copper wire composition of compacting pressing or the conductor of the soft circular copper wire composition of non-multiply of pressing, preferentially select the zinc-plated soft structure conductor of 5 class.
This whole cable 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 propagate in the medium between internal and external conductor, and therefore have decay little, shielding properties is high; And control conductor is set up in outer conductor, signal transmission and control action can be played simultaneously; Compared with prior art do not increase new reinforcement structure, the construction of cable is simple, and the outside diameter of cable is less, conveniently lays.
The above is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, under the premise without departing from the principles of the invention, can also make some modification and improvement, and these also should be considered as belonging to protection scope of the present invention.
