Description
Technical field
The utility model relates to a kind of cable, specifically a kind of novel cable with anti-flaming function.
Background technology
Cable is that electric power or information are transferred to the wire at another place from one, and the structure of wire is generally made up of external insulation layer, conductive cores, inner insulating layer etc., and inner insulating layer is positioned at outside conductive cores, and conductive cores is many and is positioned at external insulation layer; Existing external insulation layer tool has plenty of a circular cavity, and arrangements of conductors is comparatively random, and do not have anti-flaming function, during use, fail safe is poor, owing to there is such problem, so be necessary to improve existing cable.
Summary of the invention
The purpose of this utility model is deficiency in order to solve above-mentioned technology and a kind of novel cable with anti-flaming function designed.
A kind of novel cable with anti-flaming function designed by the utility model, comprise external insulation layer, described external insulation layer has inner chamber, in inner chamber, be provided with conductive cores, is provided with fire-retardant powder in described inner chamber, and described conductive cores is arranged side by side by copper cash and aluminum steel and forms; Be surrounded by screen in the outside of conductive cores, be surrounded by inner insulating layer in the outside of screen; Equidistantly be provided with protuberance at the inner surface of external insulation layer, be provided with silicones hollow tube in the center of inner chamber, the hollow section of described silicones hollow tube is regular polygon; The limit number of the quantity of described conductive cores, the quantity of protuberance and regular polygon is consistent; Described silicones hollow tube be circumferentially spaced arc convex, the spacing between described arc convex and protuberance is less than the external diameter of inner insulating layer; Described conductive cores under the restriction of silicones hollow tube between adjacent two protuberances.
Described fire-retardant powder is magnesium hydroxide flame retardant powder or aluminium hydroxide flame-retardant powder or the fire-retardant powder of nano-zinc borate.
The novel cable with anti-flaming function designed by the utility model, its beneficial effect is: first, and conductive cores is arranged side by side by copper cash and aluminum steel and forms, and enhances conductive capability, secondly, the quantity of conductive cores and the quantity of protuberance are identical, conductive cores under the restriction of silicones hollow tube between adjacent two protuberances, so in use between conductive cores mutually every must be just distant, not easily there is the problem of short circuit each other, during use, fail safe is better, circumferentially arc convex has been spaced due to silicones hollow tube, arc convex can reduce the distance between silicones hollow tube and protuberance, and its limit function to conductive cores also can not be affected when silicones hollow tube rotates, spacing between described arc convex and protuberance is less than the external diameter of inner insulating layer, can prevent conductive cores from running off displacement like this, and the setting of silicones hollow tube is to make cable conductive cores can be made to be cushioned when being subject to external force, prevent conductive cores, screen and inner insulating layer breakage, moreover the outside of conductive cores is surrounded by screen, be surrounded by inner insulating layer in the outside of screen, screen can play shield effectiveness, and be particularly suitable for when holding wire use, inner insulating layer can improve the insulation property between conductive cores further, finally, in the inner chamber of external insulation layer, be provided with fire-retardant powder, when condition of a fire external insulation layer occurring and being blown, fire-retardant powder release, can play flame retardant effect, improve fail safe when using.
