Description
Technical field
The present invention relates to a kind of cable, relate in particular to a kind of electric wire.
Background technology
In recent years, along with socioeconomic development, electric power, telecommunications industry have been penetrated in daily life, and cable, as the carrier of signal transmission, is widely used.
Electric wire mainly comprises bare wire, electromagnetic wire and insulated electric conductor, power cable, telecommunication cable and optical cable for electrical equipment and electrical.
As shown in Figure 1, electric wire generally includes outer jacket 1, sheath 2, the first screen 31, at least one insulating barrier 4 and at least one conductor 5, wherein insulating barrier 4 is around this conductor 5, the first screen 31 is around insulating barrier 4, outer jacket 1 is around the first screen 31, and sheath 2 is filled between outer jacket 1 and the first screen 31.
Due to the first screen 31 from conductor 5 close to, be subject to the electrostatic influence of electric current on conductor and generation thereof larger, easily damaged, and when the quantity of conductor 5 is more, the electrostatic interaction between conductor is also comparatively strong, thereby has more accelerated the consume of the first screen.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of electric wire, this electric wire is by setting up a secondary shielding layer, thus the electrostatic screen function of reinforcement electric wire itself.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of electric wire, comprise outer jacket, sheath, the first screen, secondary shielding layer, at least one insulating barrier and at least one conductor, wherein this insulating barrier is around this conductor, this first screen is around this insulating barrier, this outer jacket is around this first screen, this sheath is filled between this outer jacket and this first screen, and this secondary shielding layer is located between this sheath and this outer jacket.
As a further improvement on the present invention, this conductor is comprised of at least one plain conductor.
As a further improvement on the present invention, the thickness of this outer jacket is more than 2mm.
As a further improvement on the present invention, this sheath is filled between this first screen and this secondary shielding layer, and leaves certain interval.
As a further improvement on the present invention, the perimeter of section of this first screen is greater than the perimeter of section of this insulating barrier.
As a further improvement on the present invention, the perimeter of section of this secondary shielding layer is greater than the perimeter of section of this sheath.
As a further improvement on the present invention, the cross section of this outer jacket is cirque structure.
As a further improvement on the present invention, the cross section of this first screen is cirque structure.
The invention has the beneficial effects as follows: the invention provides a kind of electric wire, this electric wire is by setting up a secondary shielding layer, thus the electrostatic screen function of reinforcement electric wire itself.
Accompanying drawing explanation
Fig. 1 is the schematic cross-section of electric wire of the prior art;
Fig. 2 is the schematic diagram of electric wire of the present invention;
Fig. 3 is that Fig. 2 is along the schematic cross-section of A-A ' direction.
Embodiment
To in detail each embodiment of this case be described in detail below, and coordinate diagram as illustration.Except these are described in detail, the present invention can also be implemented in other embodiment widely, the substituting easily of any described embodiment, revise, equivalence changes and is included in the scope of this case, and with after the scope of the claims be as the criterion.In the description of specification, in order to make reader have more complete understanding to the present invention, many specific detail are provided; Yet the present invention may, at clipped or all under the prerequisite of these specific detail, still can implement.In addition, well-known step or element are not described in details, with the restriction of avoiding causing the present invention unnecessary.Assembly identical or similar in diagram will represent with identical or simileys.Pay special attention to, diagram is only the use of signal, is not size or the quantity of representation element reality, unless otherwise specified.
As shown in Figure 1, electric wire 10, comprise outer jacket 1, sheath 2, the first screen 31, secondary shielding layer 32, at least one insulating barrier 4 and at least one conductor 5, wherein insulating barrier 4 is around this conductor 5, the first screen 31 is around insulating barrier 4, outer jacket 1 is around the first screen 31, and this sheath 2 is filled between outer jacket 1 and the first screen 31, and secondary shielding layer 32 is located between sheath 2 and outer jacket 1.
Wherein, outer jacket 1 is comprised of plastics, rubber or its composition, because outer jacket 1 is positioned at the most external of electric wire 10, directly contacts with external environment condition, on the one hand, easily be subject to the impact of external environment condition, such as Exposure to Sunlight or rain drop erosion etc., on the other hand, need to guarantee that cable internal structure is not subject to the impact of external environment condition, and when internal structure is damaged, can effectively prevent the situations such as electric leakage, therefore more than the thickness of outer jacket 1 should be 2mm.
The material of sheath 2 is generally polyvinyl chloride, it is filled between what the first screen 31 and outer jacket 1, for stablizing of internal structure, sheath 2 should be filled the space between full the first screen 31 and secondary shielding layer 32, if but between the first screen 31 and secondary shielding layer 32 without any gap, can cause again other structures due to too fixing and easily damage, therefore this sheath 2 is filled between this first screen 31 and this secondary shielding layer 32, and leave certain interval.
The first screen 31 is generally metallic film material.The perimeter of section of the first screen 31 is greater than the perimeter of section of this insulating barrier, to guarantee the first screen 31 coated insulation layer 4 completely, thereby forms the electric field shielding of sealing.The first screen 31, around insulating barrier 4, can be by being wound around or coated mode.The cross section of the first screen 31 is cirque structure.
The material of insulating barrier 4 be oil-paper, rubber, polyvinyl chloride or polyethylene one of them, for the protection of conductor 5.
In sum, the invention provides a kind of electric wire, this electric wire is by setting up a secondary shielding layer, thus the electrostatic screen function of reinforcement electric wire itself.
