Abstract
Disclosed in the utility model is a self-supporting coaxial cable that comprises a conductor (1), an adhesive layer (2), an insulating layer (3), a shielding layer and an outer sheath (6). The adhesive layer (2) enables the conductor (1) and the insulating layer (3) to be integrated into one; and the shielding layer is a composite shielding layer. According to the utility model, all the components of the coaxial cable form an integrated one. Therefore, during the overhand or suspending laying process, the force is exerted on the whole cable, so that the weight of the cable can be supported. Therefore, on the overhead or suspension condition, the cable can be used normally without fracture due to the weight of the cable.
Description
Technical field
The utility model relates to the construction of cable, relates 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 with such cable called after coaxial cable.Be electrically connected performance preferably though existing coaxial cable has, because structure is comparatively complicated, weight is bigger, when built on stilts or unsettled laying, might rupture because not bearing self overall weight.
The utility model content
The technical problems to be solved in the utility model is that the defective at the prior art coaxial cable can not bear own wt etc. provides a kind of self-bearing type coaxial cable.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of self-bearing type coaxial cable is provided, comprises conductor, adhesive phase, insulating barrier, screen and oversheath; Adhesive phase is combined as an integral body with conductor and insulating barrier; Screen is composite shielding layer.
Preferably, described conductor is twisted into the ultra-fine bare copper wire of bundle for the multiply essence.
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 copper wire braid.
Preferably, described copper wire braid 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 utility model, have the following advantages or beneficial effect: each part of coaxial cable forms an integral body, integral body is stressed in built on stilts or unsettled laying, can bear the weight of self, guarantee that under built on stilts or unsettled situation, coaxial cable still can normally use and not rupture because of own wt.
Description of drawings
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, the accompanying drawing of required use is done simple the introduction in will describing embodiment below, obviously, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings, in the accompanying drawing:
Fig. 1 is the cross sectional representation of the utility model self-bearing type coaxial cable embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, the various embodiment that hereinafter will describe will be with reference to corresponding accompanying drawing, these accompanying drawings have constituted the part of embodiment, have wherein described and have realized the various embodiment that the utility model may adopt.Should understand, also can use other embodiment, perhaps this paper listed examples be carried out modification on the 26S Proteasome Structure and Function, and can not break away from scope of the present utility model and essence.
In a kind of self-bearing type coaxial cable embodiment that the utility model provides, as shown in Figure 1, comprise conductor 1, adhesive phase 2, insulating barrier 3, screen and oversheath 6.Wherein, conductor 1 is twisted into the ultra-fine bare copper wire material of bundle for the multiply essence, and in the present embodiment, per share copper wire external diameter maximum can be 0.16mm.
In self-bearing type coaxial cable embodiment, adhesive phase 2 is combined as an integral body with conductor 1 and insulating barrier 3, namely outside conductor 1, coat the characteristic material that one deck has binder performance, and then at the peripheral coated insulation layer 3 of adhesive phase 2, effect by adhesive, with conductor 1 and insulating barrier 3(insulation PE) be combined into a complete integral body, and the thickness of adhesive phase 2 can be 0.01mm-0.5mm, 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 copper wire braid 5.Aluminium foil lapping layer 4 adopts wrapped technology, and aluminium foil closely is coated on the insulating barrier 3, has solved the loose deficiency of vertical job contract skill aluminium foil commonly used.This aluminum foil thickness can be 20 μ m-30 μ m, and present embodiment is preferably 28 μ m.In addition, copper wire braid 5 is coated on the periphery of aluminium foil lapping layer 4.
The material of oversheath is polyvinyl chloride (PVC) material, namely adopts the PVC material to coat outside screen, and the PVC material can increase proper additive according to the demand of environment for use in PVC, thereby satisfies various environment to the user demand of cable.
Polyvinyl chloride, Polyvinylchloride, PVC, the thermoplastic resin that under the initator effect, is polymerized 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 bigger polydispersity, and molecular weight increases with the reduction of polymerization temperature; No definite melting point, 80～85 ℃ begin to soften, and 130 ℃ become the viscoelastic attitude, and 160～180 ℃ begin to change into viscous state; Mechanical performance is preferably arranged, about tensile strength 60MPa, impact strength 5～10kJ/m2; Excellent dielectric property are arranged.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 descends rapidly, must add stabilizer in actual applications to improve the stability to light and heat.
Each part of this coaxial cable forms an integral body, and integral body is stressed in built on stilts or unsettled laying, and can bear the weight of self.According to practical proof, the coaxial cable of present embodiment is no more than under the situation of 500m at built on stilts or flying height, can normally use and can not rupture because of own wt.
The above only is preferred embodiment of the present utility model, and those skilled in the art know, under the situation that does not break away from spirit and scope of the present utility model, can carry out various changes or be equal to replacement these features and embodiment.In addition, under instruction of the present utility model, can make amendment to adapt to concrete situation and material to these features and embodiment and can not break away from spirit and scope of the present utility model.Therefore, the utility model is not subjected to the restriction of specific embodiment disclosed herein, and all interior embodiment of claim scope that fall into the application belong to protection range of the present utility model.
