Abstract
The utility model discloses a video wire, comprising a copper core, a transparent insulating layer, a shielding layer and an oversheath. The copper core is arranged in the transparent insulating layer; the shielding layer is arranged on the transparent insulating layer; the oversheath is arranged on the shielding layer; the shielding layer is a copper wire mesh braiding structure. According to the mode, the video wire has the characteristics of simple structure, good use effect, stable signals and long service life.
Description
Technical field
The utility model relates to communications cable field, particularly relates to a kind of video line.
Background technology
Along with the development of society and the raising of technical merit, video equipment all is widely used in every field, and as computer realm, TV domain, field of video monitoring, video publicity field etc., these video equipments all be unable to do without video line.Usually, video line requires that shielding properties is preferably arranged, and the structure of conventional video line comprises two-layer, i.e. conductor inside and be coated on the heart yearn bed of material (or claiming insulating barrier) of conductive surface, and the manufacturing process of the heart yearn bed of material adopts monolayer extrusion technology.The shortcoming of conventional video line is, first, conductor and heart yearn bed of material adhesiveness be not strong, and conductor is easy to peel off, and causes the vision signal instability; The second, monolayer extrusion causes heart yearn that bubble is arranged easily, and bubble can cause the vision signal instability equally.
The utility model content
The technical problem that the utility model mainly solves provide a kind of simple in structure, result of use good, the video line of signal stabilization, long service life.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of video line is provided, comprise: copper core, transparent insulating layer, screen and oversheath, described copper core is arranged in the transparent insulating layer, described screen is arranged on the transparent insulating layer, described oversheath is arranged on the screen, and described screen is the netted braiding structure of copper wire.
In preferred embodiment of the utility model, the diameter of described copper core is 0.51mm.
In preferred embodiment of the utility model, the copper wire quantity of described screen is 96, and diameter is 0.1mm.
In preferred embodiment of the utility model, described transparent insulating layer is polyethylene layer.
In preferred embodiment of the utility model, described oversheath is pvc sheath.
The beneficial effects of the utility model are: video line of the present utility model is simple in structure, and result of use is good, signal stabilization, long service life.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model video line one preferred embodiment;
The mark of each parts is as follows in the accompanying drawing: 1, copper core, 2, transparent insulating layer, 3, screen, 4, oversheath.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection range of the present utility model is made more explicit defining.
See also Fig. 1, a kind of video line, comprise: copper core 1, transparent insulating layer 2, screen 3 and oversheath 4, described copper core 1 is arranged in the transparent insulating layer 2, described screen 3 is arranged on the transparent insulating layer 2, described oversheath 4 is arranged on the screen 3, and described screen 3 is the netted braiding structure of copper wire.
In addition, the diameter of described copper core 1 is 0.51mm.
In addition, the copper wire quantity of described screen 3 is 96, and diameter is 0.1mm, and the mesh shields layer of copper wire braiding has good shield effectiveness.
In addition, described transparent insulating layer 2 is polyethylene layer, and the polyethylene shape that is translucent has the good insulation performance.
In addition, described oversheath 4 is pvc sheath, and polyvinyl chloride has mechanical strength, insulating properties, weatherability and anti-flammability preferably.
Be different from prior art, video line of the present utility model is simple in structure, and result of use is good, signal stabilization, long service life.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
Claims (5)
1. a video line is characterized in that, comprising: copper core, transparent insulating layer, screen and oversheath, described copper core is arranged in the transparent insulating layer, described screen is arranged on the transparent insulating layer, and described oversheath is arranged on the screen, and described screen is the netted braiding structure of copper wire.
2. video line according to claim 1 is characterized in that, the diameter of described copper core is 0.51mm.
