This cable is one kind and has very strong bearing the weight of certainly and tensile strength, and resistance to compression, protection against the tide and leakproofness are good, and little, the effectual from bearing weight of tensile type coaxial cable of shielding decays.
Description
Technical field
The utility model relates to electric wire field, is specifically related to a kind of from carrying tensile type concentric cable.
Background technology
The world today steps into the information age, information has become the strategic resource of Economic development and unique production factors, with telecommunication network, computer, the present information transmission system and complete information service system that combine set up depending on multi-media terminals such as pictures, become the important symbol of a country or regional economy development degree. Concentric cable is a kind of important kind during information is transmitted, main be used as transmit by radio or receiving equipment antenna feeder and various communication, the machine intraconnections of electronics or be interconnected line. Concentric cable is made up of inner conductor layer, insulation layer, outer conductor layer and restrictive coating, inner conductor layer and the usual cross section of outer conductor layer are very little, from carrying poor performance, especially when cable uses under not buried operating mode, owing to 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 be supported by cable; concentric cable is protected by increasing the form of 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 operation causes the problem that the core of cable damages accidentally in construction process.
Chinese patent " ZL201520373236.X " discloses a kind of concentric cable, its main contents for increase enhancement Layer outside outer conductor, improve the tensile property of cable entirety to a certain extent, in laid processes, due to cable will through unwinding and rewinding around operating mode, and cable is concentrated a little at the bosom of cable point at this operating mode lower stress, central point is protected, and interior conductor tensile property is not 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, affects installation on the one hand, adds the pressure of interior conductor in load bearing process on the other hand; And the tensile property of this cable is poor, moistureproof and stopping property is poor, and bendability is worse.
Practical novel content
In order to overcome the deficiencies in the prior art, it is provided that a kind of have very strong carrying and tensile property certainly, resistance to compression, protection against the tide and good airproof performance, carrying tensile type concentric cable certainly little, that shield effectiveness is good of decaying.
For achieving the above object, the utility model discloses a kind of from carrying tensile type concentric cable, comprise interior conductor, insulation layer, buffer layer and oversheath from inside to outside; Described interior conductor by be positioned at the load bearing core at its center and taking load bearing core be some conductors conduction single lines that the center of circle is centered around outside load bearing core stranded become; Metallic conduction pipe it is provided with between insulation layer and buffer layer; Tension metal wire layer it is provided with between buffer layer and oversheath; Described tension metal wire layer is stranded side by side and become by some tension wires; Also being provided with the convex ridge of single line on oversheath, the height of the convex ridge of single line is not less than 0.5mm, and width is not less than 1mm.
Preferably, described load bearing core is galvanized steel wire.
Preferably, described interior conductor conduction single line is 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, comprise the conductor of the multiply hard round copper wire composition of compacting pressing or the conductor of the soft round copper wire composition of the non-multiply pressed, preferentially select the 5 zinc-plated soft structure conductors of class.
Preferably, described metallic conduction pipe is the hard compression tube of wrapped or vertical bag, is specially embossing pipe.
Preferably, described insulation layer 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:
The utility model has very strong from load-carrying properties, the conductor center layer You Yigen center load bearing core of cable, interior conductor concentrate in the load bearing core of center by force, cable, in folding and unfolding winding process, protects interior conductor annealing copper wire, and not frangibility; It is wound around the overall tension tensile property that tension wire improves cable simultaneously; Metallic conduction pipe compressive property is good, moistureproof and good airproof performance, and embossing can improve its bending property; Cable entirety is full symmetrical configuration, and copper wire and galvanized steel wire have function of shielding, and inner and outer conductor is in concentric position, the media that electromagnetic energy is confined between internal and external conductor, therefore has decay little, shielding properties height; Compared with prior art not increasing new reinforcing 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.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and only it is not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of the various equivalent form of value of the present utility model is all fallen within the application's claims limited range by those skilled in the art.
As shown in Figure 1, the utility model provides a kind of from carrying tensile type concentric cable, comprises interior conductor, insulation layer 3, buffer layer 5 and oversheath 7 from inside to outside; It is mainly, described interior conductor by be positioned at the load bearing core 1 at its center and taking load bearing core be 6 conductors conduction single lines 2 that the center of circle is centered around outside load bearing core stranded become, but make cable inner conductor concentrate in the load bearing core of center by force, cable is in folding and unfolding winding process, protect interior conductor annealing copper wire, and not frangibility; Being provided with metallic conduction pipe 4 between insulation layer 3 and buffer layer 5 so that cable machinery intensity height, compressive property are good, moistureproof and good airproof performance, embossing can improve the bending property of cable; Tension metal wire layer it is provided with between buffer layer 5 and oversheath 7;Described tension metal wire layer is stranded side by side and become by some tension wires 6; Also being provided with the convex ridge 8 of single line on described oversheath 7, the height of the convex ridge 8 of described single line is not less than 0.5mm, and width is not less than 1mm, for the identification of cable.
