Abstract
The utility model discloses a tensile signal shielding cable which comprises a conductor, an insulating layer, a taping layer, a shielding layer and a sheath layer. The insulating layer is arranged on the outer wall of the conductor; the conductor and the insulating layer are arranged in the taping layer; the shielding layer is arranged on the outer wall of the taping layer; and the sheath layer is arranged on the outer wall of the shielding layer. The tensile signal shielding cable is characterized in that a bearing core is arranged in the taping layer. Compared with the exiting conventional signal shielding cable, the tensile signal shielding cable has the advantages that the tensile bearing core with a bearing function is added, so that the tensile strength of the cable is improved, additional hang lines can be saved during long-path overhead installation, and one-time direct overhead installation can be realized; and besides, as the insulating layer, the shielding layer and the sheath layer are formed outside the bearing core, corrosion of the bearing core can be effectively prevented, and the service life of the cable is prolonged.
Description
Technical field
The utility model relates to a kind of improvement with the signal shielding cable that carries pulling force, a kind of specifically tensile type signal shielding cable.
Background technology
Signal shielding cable is applicable to the connecting line of rated voltage 450/750V and following control, monitoring circuit and protection circuit, is mainly used in anti electromagnetic wave and disturbs, needs shielded place.Because of main effect is that transmission signals or control circuit are main, be main so sectional area amasss with small bore, mostly between 0.5-1.5 square, the core number does not wait from the 2-61 core.Present used signal shielding cable; Constitute by conductor, insulating barrier, packed layer, lapping layer, screen and restrictive coating; Conductor has two kinds of single core and multicores, and insulation has two kinds of polyvinyl chloride and polyethylene, and the insulation employing is regular stranded; Outer wrapped polyester band or other non-absorbent materials, sheath adopts polyvinyl chloride or polyethylene.Its weak point is: because sectional area is less, it is big that core is counted difference, lays, all can receive when using the effect of external force in installation, causes conductor core wire fracture no power, thereby cause signal controlling out of control or produce mistake, causes big safety responsibility accident.
Summary of the invention
The purpose of the utility model be to provide a kind of cost low, can carry certain pulling force, long service life, can realize that large span installs the tensile type signal shielding cable lay.
For reaching above purpose; The technical scheme that the utility model adopted is: the tensile type signal shielding cable, comprise conductor, insulating barrier, lapping layer, screen and restrictive coating, and the conductor outer wall is provided with insulating barrier; Conductor and insulating barrier are located in the lapping layer; The lapping layer outer wall is provided with screen, and the outer wall of screen is provided with restrictive coating, it is characterized in that: in lapping layer, be provided with load bearing core.
The utility model is also implemented through following measure: described load bearing core is located at the center of lapping layer.
The conductor of described load bearing core and outsourcing insulation is stranded to be one.
The outer wall of described load bearing core is provided with insulating barrier.
Be provided with packed layer between described insulating barrier and the lapping layer.
The beneficial effect of the utility model is: compare with present conventional signal shielding cable; Increased the load bearing core of the tension of concrete bearing function, thereby effectively improved the tensile strength of product, the time greatly apart from built on stilts laying; Saved and added hanging wire, can disposablely directly make somebody a mere figurehead and lay; And because load bearing core has insulating barrier, screen and restrictive coating outward, can effectively prevent the load bearing core oxidation and rusting, prolong the useful life of product.
Description of drawings

Fig. 2 analyses and observe enlarged diagram for another embodiment cross section of the utility model;
Among the figure: 1, conductor; 2, load bearing core; 3, insulating barrier; 4, packed layer; 5, lapping layer; 6, screen; 7, restrictive coating.
Embodiment
Make the utility model with reference to accompanying drawing 1,2.This tensile type signal shielding cable comprises conductor 1, insulating barrier 3, lapping layer 5, screen 6 and restrictive coating 7, and conductor 1 outer wall is provided with insulating barrier 3; The position of load bearing core 2 has two kinds to be respectively Fig. 1, shown in Figure 2, and conductor 1 is located in the lapping layer 5 with insulating barrier 3, and lapping layer 5 outer walls are provided with screen 6; The outer wall of screen 6 is provided with restrictive coating 7, it is characterized in that: in lapping layer 5, be provided with load bearing core 2, load bearing core 2 is processed by metal material; In that being arranged, external force does the time spent; At first let load bearing core 2 stressed, and other conductors 1 can not be stressed, thereby reach the purpose of carrying stretching resistance.
Described load bearing core 2 is located at the center of lapping layer 5, like Fig. 2.
The conductor 1 of described load bearing core 2 and outsourcing insulation 3 is stranded to be one, like Fig. 1.
The outer wall of described load bearing core 2 is provided with insulating barrier 3.
Be provided with packed layer 4 between described insulating barrier 3 and the lapping layer 5, packed layer 4 is processed by packing material, makes the product appearance rounding.
When making the utility model, outer stranded conductor is owing to existing Haul Rate, such as 20 times Haul Rate; It twists into coefficient 1.012, that is to say per 1000 rice noodles, and skin is longer 12 meters than internal layer; Internal layer is the shortest in other words, for making the product appearance rounding, can suitably add partially filled material; External application polyester band or other non-hygroscopic materials are processed lapping layer, add braid shielded or lapped shielding layer, extrude restrictive coating at last.
