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; the control wire core is added in the outer conductor, so that the cable can realize signal transmission and signal control at the same time; compared with the prior art, no new reinforcing structure is added; and the cable is simple in structure, small in outer diameter, and convenient to lay.
Description
Technical field
The present invention relates to electric wire field, be specifically related to a kind of from the coaxial composite cable of carrying.
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.Coaxial cable is made up of inner conductor layer, insulating barrier, outer conductor layer and restrictive coating, inner conductor layer and the usual cross section of outer conductor layer very little, from carrying poor performance, especially when cable uses under not buried operating mode, because load-carrying properties are poor, cable own wt can make cable conductor break, and is also easily damaging tiny cable conductor when constructing simultaneously.Prior art dish adopts bracing frame to support cable; coaxial cable is protected by the form increasing bracing frame; there is certain effect; but add laid down cost and time; in addition the load-carrying properties of cable own are poor, unavoidably can because accidentally operate the problem causing the core of cable to damage in work progress.
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 have very strong from load-carrying properties, decay little, shield effectiveness good, can play simultaneously signal transmission and control action from the coaxial composite cable of carrying.
For achieving the above object, the invention discloses a kind of from the coaxial composite cable of carrying, comprise inner wire, insulating barrier, outer conductor and oversheath from inside to outside; Described inner wire is by being positioned at the load bearing core at its center and being that the center of circle some inner wires be centered around outside load bearing core conduct electricity that single line is stranded to be formed with load bearing core; Outer conductor is conducted electricity after single line apart windings by the identical bearing metal silk of quantity and outer conductor 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 load bearing core and bearing metal silk are zinc-coated wire.
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 has very strong from load-carrying properties, the conductor center layer You Yigen center load bearing core of cable, and the stress point of inner wire concentrates in the load bearing core of center, and cable, in folding and unfolding winding process, protects inner wire annealing copper wire, and not frangibility.Outer conductor is wound around by outer conductor zinc-coated wire, outer conductor annealing copper wire gap simultaneously, and when carrying, cable outer conductor each several part not only uniform force, also improves the tensile property of inner wire annealing copper wire; 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.
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.
