Abstract
The invention belongs to a bus provided with mutually replaced return cables and shielding layers. The bus comprises a jacket (1), a collinear jacket (2) in a power supply, a total shielding layer (3) and signal wire jackets (4), and is characterized in that signal wire shielding layers (5) are uniformly fixed on the peripheries of the two signal wire jackets (4), and a power supply collinear core (7) is arranged in the total shielding layer (3); and signal wire cores (6) are arranged in the signal wire jackets (4). The bus has the benefits as follows: the original two extra-low voltage power lines are changed into one, shielding wires of the signal wires can serve as the return cables of the power line, the return cables of the power line can serve as the shielding wires, the transmission channel of the signal wires is wide, the anti-electromagnetic interference is high, the structure is simple, environmental protection is facilitated, and energy saving and consumption reduction are realized.
Description
Technical field
The invention belongs to cable, particularly a kind of return wire and the mutual displaced type bus of screen.
Background technology
All kinds of universal serial bus common are in the market all generally have a pair or several to heart yearn as holding wire, for transmission tone vision signal and control signal etc.Also have two heart yearns in addition as light current power supply.For improving holding wire frequency range and electromagnetism interference performance, general online right skin is all provided with screen.Strict along with to environmental requirement, cable industry is also actively carrying out environment-friendly products, is exactly reduce the overall dimension of electric wire as far as possible, makes it miniaturized to the cable most important, lightweight and reduce the use of plastic material, reaches energy-saving and cost-reducing object.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, provide a kind of Signal transmissions channel wide, electromagnetism interference performance is strong, is conducive to return wire and the mutual displaced type bus of screen of environmental protection and energy saving consumption reduction.
The technical scheme that technical solution problem of the present invention adopts is: a kind of return wire and the mutual displaced type bus of screen, comprise the conllinear sheath in sheath, power supply, total shielding, holding wire sheath, it is characterized in that around two holding wire sheaths, be fixed with holding wire shielding uniformly, at the in-built power supply conllinear core of total shielding; At holding wire sheath built with signal core.
The invention has the beneficial effects as follows: originally two light current power lines become one, the shielding conductor of holding wire is as the return wire of power line; The return wire of power line also can be used as shielding conductor; Holding wire transmission channel is wide, and electromagnetism interference is strong, and structure is simple, is conducive to environmental protection, energy-saving and cost-reducing.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, illustrate with embodiment.
Fig. 1 is return wire and screen mutual displaced type bus structures sectional drawings.
In Fig. 1: 1-sheath; Conllinear sheath in 2-power supply; 3-always shields; 4-holding wire sheath; 5-holding wire shields; 6-signal core; 7-power supply conllinear core.
Embodiment
Embodiment, with reference to accompanying drawing, a kind of return wire and the mutual displaced type bus of screen, comprise the conllinear sheath 2 in sheath 1, power supply, always shield 3, holding wire sheath 4, it is characterized in that around two holding wire sheaths 4, be fixed with holding wire shielding 5 uniformly, at total shielding 3 in-built power supply conllinear cores 7; At holding wire sheath 4 built with signal core 6.
The shielding form of signal core 6 can be steel wire programming structure, also can be steel wire winding structure, can also be the attached ground configurations of aluminium foil, also can be combining structure.Holding wire shielding 5 and return wire phase double replacement; Sheath 1 adopts and meets the environmental protection instructions such as European Union ROHS and REACH; and the Novel environment-friendlymaterial material completely not containing halogen (fluorine, chlorine, bromine, iodine); electric wire is being heated, and can not discharge harmful substance, even if free fire by photooxidation resistance and Long-Time Service to environment (air, soil, water); also can not burn easily; can not be fuming, to the people being in fire hazard environment, play certain protective effect; avoid Poisoning choke, allow people have enough escape time.
Claims (1)
1. a return wire and the mutual displaced type bus of screen, comprise the conllinear sheath (2) in sheath (1), power supply, total shielding (3), holding wire sheath (4), it is characterized in that around two holding wire sheaths (4), be fixed with holding wire shielding (5) uniformly, total shielding (3) in-built power supply conllinear core (7); At holding wire sheath (4) built with signal core (6).
