Abstract
The utility model relates to a USB (Universal Serial Bus) data wire comprising a conducting wire group, insulating layers, an outer covering layer, an aluminum foil layer and an earth wire; the conducting wire group is provided with two signal wires twisted counterclockwise and two independent power lines; the insulating layers are wrapped on the signal wires and the power lines; the outer coating layer is wrapped on the conducting wire group; the aluminum foil layer is arranged between the conducting wire group and the outer coating layer; the USB data wire is further provided with a woven layer; the woven layer is arranged between the aluminum foil layer and the outer coating layer, and the earth wire is arranged between the woven layer and the aluminum foil layer; according to the USB data wire, the aluminum foil layer and the woven layer are matched to realize a double-shielding effect; and the USB data wire has the advantages of good characteristic impedance, good shielding performance, small internal delay, small attenuation and the like.
Description
Technical field
The utility model relates to a kind of connection cable of transfer of data, particularly a kind of usb data line.
Background technology
USB is the most a kind of external bus standard of using on the PC field, and what be used for standard computer and external equipment is connected and communication the plug and play of USB interface support equipment and warm connection function.Along with the computer hardware develop rapidly, the application of usb data line has increased the speed of transfer of data between external equipment, and the raising of speed means exactly that for user's largest benefit the user can use more efficient external equipment.
The utility model content
The purpose of this utility model is to overcome the defective that prior art exists, and provides that a kind of characteristic impedance is good, advantages of good shielding performance, internally postpones usb data line little, that decay is little.
The technical scheme that realizes the utility model purpose is: a kind of usb data line has wire group, insulating barrier, serving, aluminium foil layer and ground wire; Described wire group has independently power line of two counterclockwise stranded holding wires and two; All be coated with insulating barrier on described holding wire and the power line; Described serving is coated on the wire group; Described aluminium foil layer is arranged between wire group and the serving; Also has braid; Described braid is arranged between aluminium foil layer and the serving, is provided with ground wire between braid and the aluminium foil layer.
The described braid of technique scheme is formed by metal wire knitted.
The conductor of the described holding wire of technique scheme, power and ground is by 7 stranded compositions of copper wire.
After adopting technique scheme, the utlity model has following positive effect:
The utility model increases braid; Braid is arranged between aluminium foil layer and the serving, is provided with ground wire between braid and the aluminium foil layer; Cooperate the effect that reaches double shield by aluminium foil layer and braid; Have that characteristic impedance is good, advantages of good shielding performance, internally postpone the advantages such as little, that decay is little.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model, wherein according to specific embodiment also by reference to the accompanying drawings
Fig. 1 is cross section structure schematic diagram of the present utility model;
1. wire groups among the figure, 11. holding wires, 12. power lines, 2. insulating barrier, 3. serving, 4. aluminium foil layer, 5. ground wire, 6. braid.
Embodiment
(embodiment 1)
