Wherein, " GND " represents ground wire, " MHL+/-" represent MHL holding wire, " VBUS " represents voltage signal line, and " CBUS " represents control signal wire, " D+/-" represent usb signal line, " R " represents reserved, and "/" represents that this stitch is unsettled and do not connect any holding wire.
Main purpose of the present invention is to provide can be distinguished or the cable designs of simultaneously individual transmission MHL signal and usb communication/power supply, and the setting of the stitch of each connector above-mentioned is the present invention's one implementation, and the present invention is not limited to this.
The internal structure of the first cable 100, second cable 200 of the present invention, the 3rd cable 300 is described respectively referring to Fig. 2-4.
First cable 100 is from inside to outside followed successively by line group, the aluminium foil 2 of covering thread group, the braiding copper mesh 3 of coated aluminium foil 2, oversheath 5, is also filled with filler 4 in the space between online group and aluminium foil 2.The line group of the first cable 100 is the first usb signal line group, comprises positive and negative usb signal line 101 and VBUS voltage signal line 102, arranges respectively and be coated with insulating barrier 1 around positive and negative usb signal line 101.Be utilize aluminium foil 2 to be connected with the GND stitch of USB connector 11 respectively with braiding copper mesh 3 in first cable 100, inner foil 2 and outside copper mesh braiding 3 form double layer screen, and shield effectiveness is better, and signal quality also can be better.As can be seen from Figure 2, can no longer need special ground wire in the first usb signal line group under this scheme, this is conducive to the wire diameter of reduction first cable 100.
Second cable 200 is from inside to outside followed successively by line group, the aluminium foil 2 of covering thread group, the braiding copper mesh 3 of coated aluminium foil 2, oversheath 5.The line group of the second cable 200 is a MHL line group, comprises positive and negative MHL holding wire 104, GND ground wire 103 and CBUS signal control line the 105, one periphery aluminium foil 6 of MHL line group coated, aluminium foil 6 shielding actions.Be utilize aluminium foil 2 to be connected with the GND stitch of MHL connector 12 respectively with braiding copper mesh 3 in second cable 200, inner foil 2 and outside copper mesh braiding 3 form double layer screen, and shield effectiveness is better, and signal quality also can be better.
Time existing mobile device exports MHL audio-video signal, self can produce a large amount of heats, if receiving terminal is simultaneously for this charging of mobile devices can cause mobile device to generate heat more, as can be seen from Figure 3, a MHL line group in the present invention does not comprise voltage signal line, this makes it possible to avoid to export in the process of MHL signal receiving terminal for its charging at mobile device causes mobile device too to generate heat, this set is conducive to the battery life extending mobile device, is conducive to the Long-Time Service of mobile device.
3rd cable 300 is from inside to outside followed successively by line group, the aluminium foil 2 of covering thread group, the braiding copper mesh 3 of coated aluminium foil 2, oversheath 5.The line group of the 3rd cable 300 comprises the 2nd MHL line group and the second usb signal line group and ground wire 106.It is coated that 2nd MHL line group comprises positive and negative MHL holding wire 104, GND ground wire 103 and CBUS signal control line the 105, two periphery aluminium foil 6 of MHL line group, aluminium foil 6 shielding actions.Second usb signal line group comprises positive and negative usb signal line 101 and VBUS voltage signal line 102.Be utilize aluminium foil 2 to be connected with the GND stitch of USB/MHL integrated connector 13 respectively with braiding copper mesh 3 in 3rd cable 300, inner foil 2 and outside copper mesh braiding 3 form double layer screen, and shield effectiveness is better, and signal quality also can be better.
Therefore, first cable 100 of the present invention is integrated with USB differential signal line and a USB supply lines (voltage signal line VBUS) of two standards, second cable 200 is integrated with MHL differential signal line and a CBUS control signal wire of two standards, 3rd cable 300 is integrated with one article of USB supply lines (voltage signal line VBUS), the two pairs of differential signal lines (transmitting usb signal and MHL data respectively), and a CBUS control signal wire and two GND lines.In order to reduce the diameter of cable, the metallic member of the shell of all corresponding with it connector of the copper mesh of every one end braiding and GND stitch are connected.Further, in order to better shielding high-speed holding wire is to external radiation and shield the interference of other radiation to holding wire, can also by two pairs of HW High Way entirety coated aluminium foil connect GND line respectively.
The present invention has multiple connected mode:
Connected mode 1, use as usb communication/power supply: USB connector 11 connects USB transmitting terminal and USB/MHL integrated connector 13 connects USB receiving terminal, or USB connector 11 connects USB receiving terminal and USB/MHL integrated connector 13 connects USB transmitting terminal, and USB transmitting terminal is powered to USB receiving terminal.
Connected mode 2, uses as MHL Signal transmissions: MHL connector 12 connects MHL transmitting terminal and USB/MHL integrated connector 13 connects MHL receiving terminal, or MHL connector 12 connects MHL receiving terminal and USB/MHL integrated connector 13 connects MHL transmitting terminal.
Connected mode 3, power and MHL transmission use as USB: USB connector 11 is connected feeder ear (such as connecting power supply adaptor) simultaneously, MHL connector 12 connects MHL transmitting terminal, and USB/MHL integrated connector 13 connects MHL receiving terminal, and feeder ear is powered to MHL receiving terminal.
Connected mode 4, use with MHL transmission as usb communication/power supply: USB connector 11 is connected USB transmitting terminal simultaneously, MHL connector 12 connects MHL transmitting terminal, the equipment time-sharing multiplex that USB/MHL integrated connector 13 connects receives usb signal and MHL signal, and the equipment that USB transmitting terminal connects to USB/MHL integrated connector 13 is simultaneously powered.
Micro coaxial cable connector assembly of the present invention achieves transmission MHL signal and usb communication/power supply independently works, both can also carry out simultaneously, if need debugging updating apparatus or gather audio frequency and video passback in the process of MHL Signal transmissions, do not need to provide cable only to need to set up usb communication in addition yet.Micro coaxial cable connector assembly of the present invention is multiplexing powerful, easy and simple to handle, and existing USB standard interface can be utilized to reset, and interface compatibility and stability are all fine, maximizedly reduces cost.
Although be described in detail specific embodiments more of the present invention by example, it should be appreciated by those skilled in the art, above example is only to be described, instead of in order to limit the scope of the invention.It should be appreciated by those skilled in the art, can without departing from the scope and spirit of the present invention, above embodiment be modified.Scope of the present invention is limited by claims.
