Description
Technical field
The utility model relates to for the data wire that connects the USB interface electronic equipment.
Background technology
Along with science and technology and social progress, the popularizing of portable notebook computer, panel computer and intelligent mobile phone.As portable set, its maximum characteristics are exactly light succinct, and therefore, the standard configuration external interface of all portable type electronic products is very limited basically, generally only joins one or two USB interface, and an OTG interface is wherein generally arranged.USB OTG can make main frame, can do peripheral hardware again; Identify by the ID pin in the USB interface pin.For example, in the OTG of USB2.0 interface, have 5 pins, two pins connect data wire, and two pins connect power supply, also have an ID pin; According to the state of ID pin, system determines in transfer of data it is as DEVICE or HOST.Popularizing of smart mobile phone and panel computer more makes USB OTG function, can make main frame and can also do peripheral hardware, becomes function commonly used.
New video transmission technologies MHL also is to adopt the USB interface of 5 pins of portable equipment to export; There is the data wire of 5 bars cores to transmit in equally also needing.
Existing data wire all is the data wire of independent function; The user will realize two kinds of functions of OTG, needs to switch two data lines; Use and carry all inconveniences; Increase simultaneously production cost.And when realizing the MHL transmission, pass through a patchcord, the long HDMI line of transferring; After connecting like this, the operation portable equipment becomes very inconvenient.
Summary of the invention
For the problems referred to above, the utility model aims to provide and a kind ofly can transmit USB ID pin status signal, realizes that the master-slave equipment of portable equipment automaticallyes switch; Owing to adopting compatible USB2.0A type interface, still can be used as the generic USB data wire, portable equipment is charged and transfer of data; Can also utilize 5 bars cores in the data wire, transmission MHL vision signal.
For realizing this technical purpose, scheme of the present utility model is: a kind of Multifunctional USB data wire, comprise the second USB plug that connects Dian Nao ﹑ power supply adaptor or digital peripheral hardware for the first USB plug that connects the portable equipment port and Lian, the first USB plug is 5 pin standard USB plug that comprise the ID pin; The second USB plug is the USB plug of at least 5 pins of compatible USB2.0 A type plug; The first USB plug is connected with the second USB plug data communication and supplies and is electrically connected; ID pin in the first USB plug is connected with increase pin outside the second USB plug Plays signal pin.4 pins of the A type standard plug that comprises in the second USB plug respectively with the first USB plug in corresponding pin be connected.
As preferably, described the second USB plug adopts USB3.0 A type plug; One in the pin outside 4 USB2.0 signal pins in ID pin in the first USB plug and the second USB plug is connected.
The beneficial effect of the technical program is: use a usb data line, can connect portable equipment and Dian Nao ﹑ power supply adaptor etc. with the equipment of standard A type interface, also can be used for connecting the peripheral hardware of portable equipment and the integrated compatible USB2.0 A type interface corresponding with secondary USB interface, realize that by control ID pin status portable equipment is respectively as the several functions of main frame or terminal equipment.Can also utilize this data wire to transmit the MHL vision signal.Adopt the USB3.0 interface; Can directly use existing in batches interface product, reduce R﹠D costs, accelerate the commercialization time.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
As shown in Figure 1, a kind of Multifunctional USB data wire of the present utility model, comprise for the first USB plug 1 that connects the portable equipment port and Lian and connect the second USB plug 2, the first USB plug 1 of Dian Nao ﹑ power supply adaptor or digital peripheral hardware for comprising 5 pin standard USB plug of ID pin; The second USB plug 2 is the USB plug of at least 5 pins of compatible USB2.0 A type plug; The first USB plug 1 is connected with 2 data communication of the second USB plug and supplies and is electrically connected; ID pin in the first USB plug 1 is connected with increase pin outside the second USB plug 2 Plays signal pins.
As shown in Figure 2, the schematic diagram of standard USB2.0 A type plug.
In the standard USB A type plug 4 signal pins are arranged; Be respectively VCC ﹑ D-﹑ D+ ﹑ GND.
As shown in Figure 3, the compatible USB2.0 A type plug schematic diagram of the utility model employing:
4 signal pins in standard USB2.0 A type plug, increase the 5th pin.This compatibility plug apparent size and standard USB A type plug are in full accord, and when connection standard USB 2.0 A type interface, 4 signal pins of standard are corresponding to be connected, and the 5th pin is unsettled; When connecting compatible USB2.0 A type interface of the same race, 4 signal pins of standard are connected with increase corresponding connection of the 5th pin while.Like this, both can increase signal pin, realize the transmission of ID control signal, or the transmission of MHL vision signal; Can be connected with standard USB A type interface again and connect.
