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.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 are the least, from carrying poor performance, when especially cable uses under the most buried operating mode, owing to load-carrying properties are poor, cable own wt can make cable conductor break, and the most easily damages tiny cable conductor when in construction simultaneously.Prior art dish uses bracing frame to be supported 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 be because operation causes the problem that the core of cable damages accidentally in work progress.

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 cable adding one layer or a few Rotating fields, add manufacturing procedure, reduce production efficiency, the weight of cable adds simultaneously, on the one hand impact is installed, and on the other hand adds inner wire pressure in load bearing process, and the flexibility of cable is the poorest.

Utility model content

In order to overcome the deficiencies in the prior art, it is provided that a kind of have the strongest from load-carrying properties, decay little, shield effectiveness good, flexibility is good from bearing type coaxial single flexible cable.

For achieving the above object, the utility model discloses a kind of from bearing type coaxial single flexible cable, include inner wire, insulating barrier, outer conductor and oversheath from inside to outside；Described inner wire stranded is formed by the carrying core directly dragged at its center and the inner wire conductive monofilament that is arranged on outside carrying core；Outer conductor is formed with outer conductor conductive monofilament mixed weaving by bearing metal silk；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 carrying core and bearing metal silk are zinc-coated wire.

Preferably, described inner wire conductive monofilament and outer conductor conductive monofilament are annealing copper wire, 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 outer jacket is made up of polythene material.

The beneficial effects of the utility model are:

This utility model has the strongest from load-carrying properties, the conductor center layer You Yigen center carrying core of cable, and the stress point of inner wire concentrates on center carrying core, and cable, in folding and unfolding winding process, protects inner wire annealing copper wire, and is not easily broken；Outer conductor is entwined by outer conductor zinc-coated wire, outer conductor annealing copper wire gap simultaneously; when carrying; cable outer conductor each several part is not only the strongest from load-carrying properties by having; the conductor center layer You Yigen center carrying core of cable; the stress point of inner wire concentrates on center carrying core; cable, in folding and unfolding winding process, protects inner wire annealing copper wire, and is not easily broken；Outer conductor is by outer conductor zinc-coated wire, outer conductor annealing copper wire mixed weaving simultaneously, and when carrying, cable outer conductor each several part not only uniform force, steel wire has preferable tensile property, also improves the tensile property of inner wire；The inner wire of carrying be tangle structure, the outer conductor of carrying of bundle be braiding structure, make cable entirety have preferable flexibility；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.
