Abstract
The utility model discloses an Ethernet three-core cable. The cable comprises three conductors with fan-shaped cross sections. The conductors are coated by EPR insulating layers to form insulation wire cores. The three insulation wire cores form a cylindrical cable core. The cable core is coated by an elastic layer. Elliptical air holes are distributed in the elastic layer along an annular structure. The elastic layer is coated successively by an inner shielding layer, a winding layer and an outer shielding layer. The outer shielding layer is coated by a composite protective layer that comprises an inner foaming plastic layer and an outer EPR sheath layer. The cable is novel in structure and design, utilizes three insulation wire cores with fan-shaped cross sections to enclose a cylindrical cable core in cooperation with the design of the elastic layer, so that the structural compaction of the cable is improved, outer diameter of the cable is reduced. The composite protective layer allows the weight of the cable to be reduced, installation and laying are convenient and efficient, and the cable core is difficult to damage.
Description
technical field:
The utility model relates to cable process technology, relates in particular to a kind of Ethernet three-core cable.
background technology:
Early stage 10Mbps Ethernet is referred to as standard ethernet, goes through 100M Ethernet after the develop rapidly of last century end, at present the even just continuous range of application of expanding under the promotion of international organization and leader enterprise of 10G Ethernet of gigabit Ethernet.Ethernet can use the multiple transmission mediums such as thick coaxial cable, thin coaxial cable, unshielded twisted pair, Shielded Twisted Pair and optical fiber to be connected.
There is unreasonable part in the three-core cable structural design of using for current Ethernet, mainly poor at structural compactness, external diameter is large and weight is larger, mounting and installation inconvenience, in mounting and installation process, be easily subject to the impaired phenomenon of external force generation cable core, bring huge loss to user.
utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of Ethernet three-core cable, and structural compactness is good, has reduced the weight of cable, has reduced external diameter, is convenient to mounting and installation, and extend useful life.
The technical solution of the utility model is as follows:
Ethernet three-core cable; it is characterized in that: comprise that three cross sections are fan-shaped conductor; conductor is coated with ethylene propylene rubber insulated layer and forms insulated wire cores; three insulated wire cores form cylindrical formation cable core; cable core is coated with elastic layer; in elastic layer, there is oval-shaped pore along annular spread; elastic layer is provided with internal shield, winding layer, outer shielding layer outward successively; outer shielding layer is provided with composite protection layer outward, and composite protection layer is made up of foamed plastic layer and the outer field ethylene-propylene rubber restrictive coating of internal layer.
Described Ethernet three-core cable, is characterized in that: described internal shield, outer shielding layer adopt aluminium foil strip or the overlapping wrapped formation of aluminium-plastic tape, and the wrapped rate of putting up is not less than 15%.
Described Ethernet three-core cable, is characterized in that: described winding layer adopts galvanized steel strip spiral winding to form, and the spacing of spiral winding is not more than 1.5mm.
The utility model has the advantages that:
The utility model structural design novelty; adopting three cross sections is the structural compactness that fan-shaped insulated wire cores surrounds design that cylindrical formation cable core coordinates elastic layer and improved cable; external diameter has also reduced; simultaneously; composite protection layer has reduced the weight of cable; make mounting and installation become convenient and swift, cable conductor is not easily damaged.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
embodiment:
Referring to Fig. 1:
Ethernet three-core cable; comprise that three cross sections are fan-shaped conductor 1; conductor 1 is coated with ethylene propylene rubber insulated layer 2 and forms insulated wire cores; three insulated wire cores form cylindrical formation cable core; cable core is coated with elastic layer 3; elastic layer 3 is interior has oval-shaped pore 4 along annular spread; outer internal shield 5, winding layer 6, the outer shielding layer 7 of being provided with successively of elastic layer 3; outer shielding layer 7 is outer is provided with composite protection layer 8, and composite protection layer 8 is made up of foamed plastic layer 8-1 and the outer field ethylene-propylene rubber restrictive coating 8-2 of internal layer.
Internal shield 5, outer shielding layer 7 adopt aluminium foil strip or the overlapping wrapped formation of aluminium-plastic tape, and the wrapped rate of putting up is not less than 15%.
Winding layer 6 adopts galvanized steel strip spiral winding to form, and the spacing of spiral winding is not more than 1.5mm.
