Background technology
USB association has issued up-to-date standard usb interface: USBType-C in August, 2014, USBType-C is more frivolous, support that positive anti-plug, transmission rate are faster, more and more liked by each manufacturer and consumer, exploitation USBType-C cable is also inexorable trend, the USBType-C line of current market circulation is the specification announced with reference to USB association, be set to circle, USBType-C cable is before being welded on electric connector or circuit board, need to utilize and manually each wire is arranged by regulation order, time-consumingly to require great effort again, affect production efficiency, cost increase.
Utility model content
The purpose of this utility model there are provided a kind of USBType-C flat cable omitting arrangement wire order.
For realizing aforementioned object, the utility model adopts following technical scheme: a kind of USBType-C flat cable, it comprises two pairs of power lines, two pairs of high-speed differential signal lines, a pair low speed differential signal line, pair of control line, some earth connections and be coated on the outer quilt of insulation in outside, centrally axis is symmetrical for described USBType-C flat cable, described high-speed differential signal line, low speed differential signal line, control line and earth connection arrange this jointly between power line, described low speed differential signal line is between these two pairs of high-speed differential signal lines, wherein a pair high-speed differential signal line a pair power line and this to low speed differential signal line between, this to control line another to high-speed differential signal line and another to power line between.
As further improvement of the utility model, a pair high-speed differential signal line in described two pairs of high-speed differential signal lines is for receiving differential signal line at a high speed, and another sends differential signal line to for high speed.
As further improvement of the utility model, described high-speed differential signal line, low speed differential signal line and the control line left and right sides are separately placed with an earth connection.
As further improvement of the utility model, described high-speed differential signal line, each pair of low speed differential signal line and each pair of control line and earth connection left right-aligned bear against together with.
As further improvement of the utility model, the insulator of each self-contained conductor of described power line, differential signal line and control line and parcel conductor, earth connection is exposed wire.
As further improvement of the utility model, described high-speed differential signal line, low speed differential signal line, control line are wrapped in a screen with earth connection respectively, and earth connection abuts with screen, and screen is aluminium foil or Copper Foil.
As further improvement of the utility model, described insulation is outer to be replaced by with laterally zygomorphic two-layer insulated rubber film, and described power line, high-speed differential signal line, low speed differential signal line, control line and earth connection are clamped between this two-layer insulated rubber film fixing.
Centrally axis is symmetrical for the utility model USBType-C flat cable, described high-speed differential signal line, low speed differential signal line, control line and earth connection arrange this jointly between power line, described low speed differential signal line is between these two pairs of high-speed differential signal lines, wherein a pair high-speed differential signal line a pair power line and this to low speed differential signal line between, this to control line another to high-speed differential signal line and another to power line between, can omit wire by the tactic program of regulation, enhance productivity, reduce cost.

Fig. 2 is the cross sectional representation of another execution mode of the utility model USBType-C flat cable.
Embodiment
Refer to shown in Fig. 1, centrally axis C1 is symmetrical for the utility model USBType-C flat cable 10, and it comprises two pairs of power lines, 11, two pairs of high-speed differential signal lines 12, a pair low speed differential signal line 13 between these two pairs of high-speed differential signal lines 12, pair of control line 14, some earth connections 15 and be coated on the insulation in outside outer by 16.The each pair of high-speed differential signal line 12, each pair of low speed differential signal line 13 be placed with an earth connection 15 respectively with the left and right sides of each pair of control line 14 and with earth connection 15 left right-aligned bear against together with.Wherein a pair high-speed differential signal line 12 is for receiving differential signal line at a high speed, and another sends differential signal line to for high speed.Each power line 11, differential signal line 12,13 and control line 14 comprise the insulator of conductor and parcel conductor.Earth connection 15 is exposed wire.
High-speed differential signal line 12, low speed differential signal line 13, control line 14 and earth connection 15 arrange this jointly between power line 11.Wherein a pair high-speed differential signal line 12 a pair power line 11 and this to low speed differential signal line 13 between, this to control line 14 another to high-speed differential signal line 12 and another to power line 11 between.High-speed differential signal line 12, low speed differential signal line 13, control line 14 are wrapped in a screen 17 with earth connection 15 respectively, and earth connection 15 abuts with screen 17, and form grounded circuit, screen 17 is aluminium foil or Copper Foil.
The utility model USBType-C flat cable 10 tiled configuration is symmetrical, can to omit wire by the tactic program of regulation, enhance productivity, reduce cost.
Refer to shown in Fig. 2, another execution mode of the utility model USBType-C flat cable 20 is also the symmetrical of centrally axis C2, it is outer by 16 that this USBType-C flat cable 20 adopts laterally zygomorphic two-layer insulated rubber film 26 to be pasted together replacement insulation, power line 11, high-speed differential signal line 12, low speed differential signal line 13, control line 14 and earth connection 15 are clamped between this two-layer insulated rubber film 26 fixing, this USBType-C flat cable 20 can reach the purpose of this utility model equally: omit wire by the tactic program of regulation, enhance productivity, reduce cost.
Although be example object, disclose preferred implementation of the present utility model, but those of ordinary skill in the art will recognize, when not departing from scope and spirit of the present utility model disclosed in appending claims, various improvement, increase and replacement are possible.
