Abstract
The invention discloses a self-supporting coaxial cable which includes a conductor (1), an adhesive layer (2), an insulating layer (3), a shielding layer and external protective layer (6). The adhesive layer (2) combines the conductor (1) and the insulating layer (3) into a whole. The shielding layer is a composite shielding layer. The component parts of the coaxial cable form a whole and bear forces as a whole when the cable is laid overhead or suspended so that the cable can bear the weight of the cable; and thus it is ensured that the cable can be used normally and is free from rupture resulted from the weight of the cable itself under a condition of being laid overhead or suspended.
Description
Technical field
The present invention relates to the construction of cable, relate in particular to a kind of self-bearing type coaxial cable.
Background technology
Coaxial cable is divided into four layers from inside to outside: center copper cash (solid wire of sub-thread or stranded wire), plastic insulation, netted conductive layer and wire outer skin.Center copper cash and netted conductive layer form current circuit.Because center copper cash and netted conductive layer are coaxial relation, so by such cable called after coaxial cable.Although existing coaxial cable has good electrical connection performance, because structure is comparatively complicated, weight is larger, in the time of built on stilts or unsettled laying, likely ruptures because not bearing self overall weight.
Summary of the invention
The technical problem to be solved in the present invention is, can not bear the defect of own wt etc. for prior art coaxial cable, and a kind of self-bearing type coaxial cable is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of self-bearing type coaxial cable is provided, comprises conductor, adhesive phase, insulating barrier, screen and oversheath; Conductor and insulating barrier are combined as an entirety by adhesive phase; Screen is composite shielding layer.
Preferably, described conductor is that multiply essence is twisted into the ultra-fine bare copper wire of bundle.
Preferably, per share described copper wire external diameter is 0.16mm to the maximum.
Preferably, the thickness of described adhesive phase is 0.01mm-0.5mm, is preferably 0.1mm
Preferably, described composite shielding layer comprises aluminium foil lapping layer and proof copper-wire braided layer.
Preferably, described proof copper-wire braided layer is coated on the periphery of aluminium foil lapping layer.
Preferably, the thickness of described aluminium foil is 20 μ m-30 μ m, is preferably 28 μ m.
Preferably, the material of described oversheath is polyvinyl chloride.
Implement self-bearing type coaxial cable of the present invention, have the following advantages or beneficial effect: each part of coaxial cable forms an entirety, in built on stilts or unsettled laying, entirety is stressed, can bear the weight of self, guarantee built on stilts or unsettled in the situation that, coaxial cable still can normally use and not because of own wt fracture.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, obviously, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, in accompanying drawing:
Fig. 1 is the cross sectional representation of self-bearing type coaxial cable embodiment of the present invention.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, the various embodiment that below will describe will be with reference to corresponding accompanying drawing, these accompanying drawings have formed a part of embodiment, have wherein described and have realized the various embodiment that the present invention may adopt.Should understand, also can use other embodiment, or the embodiment enumerating is herein carried out to the modification on 26S Proteasome Structure and Function, and can not depart from the scope and spirit of the present invention.
In a kind of self-bearing type coaxial cable embodiment provided by the invention, as shown in Figure 1, comprise conductor 1, adhesive phase 2, insulating barrier 3, screen and oversheath 6.Wherein, conductor 1 is restrainted ultra-fine bare copper wire material for multiply essence is twisted into, and in the present embodiment, per share copper wire external diameter maximum can be 0.16mm.
In self-bearing type coaxial cable embodiment, conductor 1 and insulating barrier 3 are combined as an entirety by adhesive phase 2, there is the characteristic material of binder performance at conductor 1 outer cladding one deck, and then at the peripheral coated insulation layer 3 of adhesive phase 2, by the effect of adhesive, by conductor 1 and insulating barrier 3(insulation PE) be combined into a complete entirety, and the thickness of adhesive phase 2 can be 0.01mm-0.5mm, the present embodiment is preferably 0.1mm.
In self-bearing type coaxial cable embodiment, screen is composite shielding layer, and this composite shielding layer comprises aluminium foil lapping layer 4 and proof copper-wire braided layer 5.Aluminium foil lapping layer 4 adopts wrapped technique, and aluminium foil is closely coated on insulating barrier 3, has solved the conventional loose deficiency of vertical job contract skill aluminium foil.This aluminum foil thickness can be 20 μ m-30 μ m, and the present embodiment is preferably 28 μ m.In addition, proof copper-wire braided layer 5 is coated on the periphery of aluminium foil lapping layer 4.
The material of oversheath is polyvinyl chloride (PVC) material, adopts PVC material to be coated outward at screen, and PVC material can, according to the demand of environment for use, increase suitable additive in PVC, thereby meets the user demand of various environment to cable.
Polyvinyl chloride, Polyvinylchloride, PVC, the thermoplastic resin being polymerized under initator effect by vinyl chloride.Be the homopolymers of vinyl chloride, ryuron and vinyl chloride copolymer are referred to as vinyl chloride resin.PVC is the white powder of impalpable structure, and the degree of branching is less.Industrial PVC molecular weight generally, in 50,000～120,000 scopes, has larger polydispersity, and molecular weight increases with the reduction of polymerization temperature; Without definite melting point, 80～85 ℃ start to soften, and 130 ℃ become viscoelastic state, and 160～180 ℃ start to change into viscous state; There is good mechanical performance, tensile strength 60MPa left and right, impact strength 5～10kJ/m2; There are excellent dielectric property.But to the poor stability of light and heat, more than 100 ℃ or through long-time exposure in sunshine, will decompose and produce hydrogen chloride, and further autocatalysis is decomposed, cause variable color, physical and mechanical properties also declines rapidly, must add in actual applications stabilizer to improve the stability to light and heat.
Each part of this coaxial cable forms an entirety, and in built on stilts or unsettled laying, entirety is stressed, can bear the weight of self.According to practical proof, the coaxial cable of the present embodiment, in the situation that built on stilts or flying height are no more than 500m, can normally use and can not rupture because of own wt.
The foregoing is only preferred embodiment of the present invention, those skilled in the art know, without departing from the spirit and scope of the present invention, can carry out various changes or be equal to replacement these features and embodiment.In addition, under instruction of the present invention, can modify to adapt to concrete situation and material and can not depart from the spirit and scope of the present invention these features and embodiment.Therefore, the present invention is not subject to the restriction of specific embodiment disclosed herein, and the embodiment within the scope of all the application's of falling into claim belongs to protection scope of the present invention.
