Abstract
The utility model discloses a novel video transmission line which comprises the components of: an outer sheath, two intertwisted unit transmission lines, a filling rope and an anti-stress core; wherein the intertwisted unit transmission line, the filling rope and the anti-stress line core are arranged in the outer sheath; wherein the novel video transmission line is characterized in that: each unit transmission line comprises one or a plurality of copper line cores of which the cross area is 0.5 square millimeters and a polyethylene layer that coats the copper line cores; the internal diameter of the outer sheath is adapted with the diameter of an assembly which is composed of the unit transmission lines, the filling rope and the anti-stress line core; and the inner wall of the outer sheath is matched with the assembly which is composed of the unit transmission lines, the filling rope and the anti-stress line core. The novel video transmission line has functions of: saving the material of the polyethylene layer, preventing use of a metal shielding net through a self-shielding structure, saving cost, and realizing excellent pulling resistance and high insulating property. After a pulling force is applied, the inner wall of the outer sheath cooperates with the assembly which is composed of the unit transmission lines, the filling rope and the anti-stress line core, and bears the pulling force together, thereby preventing loosening or falling of a structure in the outer sheath, and ensuring high stability and high safety in video transmission.
Description
Technical field
The utility model relates to power equipment accessory field, relates in particular to a kind of Novel video transmission line.
Background technology
In power cable wire rod, especially in monitor video transmission line section product, its structure of existing video transmission line: be all often to wrap polyethylene layer with a copper wire, then skin is knitted metallic shield net, add again sheath, for example often sell on the market or common SYV75-3 75-5 video transmission line.
Yet often there is the technological deficiency of the following aspects in above-mentioned this video transmission line:
1, materials are more, and polyethylene layer is solid, after the wire rod of finished product completes substantially, need a large amount of solid plastics (being polyethylene layer), and need to use gauze screen (being metallic shield net) too much with metal charge, and the wasting of resources is too much.2, produce take a lot of work, time-consuming, in the situation that semi-finished product raw material completes, also will for example, through the very complicated operation slowly in three roads: bag polyethylene layer; Braid shielded net; Additional sheath.3, production process interrupt line or braiding go wrong and half-finished time, are difficult to process, because metallic shield net does not connect, or can connect reluctantly, during additional sheath, also easily go wrong, and unavoidably cause waste.4, pulling force is not enough during practical application, because a very thin wire plays main pulling force effect in the middle of only having, is easily out of order.5, during practical application, metallic shield net is difficult for fixing, loosening or come off, and generally uses clamp card, and the long term activity of earthquake easy loose contact of getting off, or the lousiness of metallic shield net and middle heart yearn short circuit, make monitor for faults rate so very high.6, transmission range is too near, 200 meters of left and right of general 75-3 line transmission of video, and 75-5 can be over 500 meters yet.Surpass this limit and will use Optical Fiber Transmission.
Utility model content
The purpose of this utility model is to provide a kind of Novel video transmission line, to address the above problem.
In order to achieve the above object, the technical solution of the utility model is achieved in that
A Novel video transmission line, the two mutual stranded unit transmission lines, filling cotton rope and the anti-stress core (for example: for stretch-proof stress and compression) that comprise oversheath and be arranged on described oversheath inside, wherein:
Described unit transmission line comprises one or many sectional areas are the copper core of 0.5 square millimeter and the polyethylene layer that wraps up described copper core; The diameter of the internal diameter of described oversheath and unit transmission line, filling cotton rope and the formed assembly of anti-stress core adapts; The inwall of described oversheath matches with unit transmission line, filling cotton rope and the formed assembly of anti-stress core.
