Abstract
The utility model relates to a double connector for a mobile phone and a computer, which relates to the technical field of information exchange technology between the mobile phone and the computer. The utility model comprises a charging circuit, a USB control circuit and a data communication circuit, wherein, the input end of the charging circuit is connected with a charging control end of the USB control circuit, and the output end of the charging circuit is connected with a charging end of a mobile phone interface of the connector; the data communication circuit is connected with a mobile phone interface data end of the double connector and a data line of the USB control circuit of which the other end is connected with a personal computer USB interface of the double connector. The utility model has the advantages that the structure is simple; part of the electric energy of a personal computer can be transferred to the mobile phone, and the communication line of a mobile phone can be inserted and pulled out conveniently.
Description
Technical field
The utility model relates to electronic communication and message-switching technique field, particularly realizes mobile phone and computerized information exchange correlation technology.
Background technology
Present mobile phone communication line adopts the RS232 serial port to link to each other with PC substantially, so do not possess the hot plug function, in use, must close computer power earlier, just the mobile phone communication line be can pull out, otherwise PC serial ports, mobile communication mouth or mobile communication line burnt easily.Simultaneously because when using the mobile communication line, its in public places (on airport, train, steamer) usually be that notebook computer has electricity, and the cellular phone power supplies deficiency runs into such situation, can cause many inconvenience to the user.
Technology contents
The utility model purpose is at above the deficiencies in the prior art, designs a kind of simple in structurely, can utilize connection that a part of electric weight of PC is transferred in the mobile phone, can make things convenient for the portable computer double connector of plug at any time of mobile communication line.
The utility model purpose can be achieved through the following technical solutions.
A kind of portable computer double connector is characterized in that: described connector comprises charging circuit, USB control circuit and data communication circuit; The charging control end of charging circuit input and USB control circuit joins, and the output of charging circuit and connector mobile phone interface charging end join.The connection double connector mobile phone interface data end of data communication circuit and the data wire of USB control circuit; USB control phone is electrically connected double connector PC USB interface.
The utility model technological progress is, a part of electric weight of PC can be transferred in the mobile phone by this connector, makes things convenient for the plug at any time of mobile communication line.
Description of drawings
Fig. 1 is the utility model and mobile phone, computer catenation principle block diagram;
Fig. 2 uses connection diagram for the utility model;
Fig. 3 is the utility model circuit diagram.
Specific implementation method
The PC USB interface has complete power management function, can carry out warm swap (hot plug), makes things convenient for the plug at any time of mobile communication line, uses at any time.Utilize the USB mouth except can communication, can also be to these characteristics of outside power devices, can be in PC and mobile communication, mobile phone is charged, very convenient, when especially being away from home, usually like getting in touch with note, computer can also carry out data communication simultaneously to cell-phone charging.
Utilizing PC can charge to mobile phone by the portable computer double connector, is again a data in mobile phone connection simultaneously, can allow mobile phone and PC carry out data communication by the portable computer double connector.The portable computer double connector is the interconnecting device that is connected between data in mobile phone interface (comprising charging inlet) and PC USB interface.The portable computer double connector can be packaged into a connecting line.
The portable computer double connector comprises charging circuit 1, USB control circuit 2 and data communication circuit 3 three parts.As shown in Figure 1, also comprise double connector mobile phone interface 4 and the double connector PC USB interface 5 that is connected with mobile phone and PC as double connector.The root HUB of two USB is generally all arranged on PC, and the USB controller on the portable computer double connector sends the USB control command to PC, (data communication, the power management etc.) management of being correlated with.
In actual use, as shown in Figure 3 at USB control circuit 2, Key Circuit is the CY7C63723 chip, this chip is 8 bit CPUs with USB interface of CYPRESS company, and we utilize its P1.0, and the P1.1 pin is respectively as the transmission (TX) of serial data communication with accept (RX), communication baud rate has the chip clock generating, P0.2 then is used as charging control 10, and when PC was not want mobile phone charged, the P0.2 bottom set got final product.Otherwise, charge.
MC34063 is the DC-DC power supply control chip that motorola inc produces, and is a kind of charge controlling chip of extensive employing, and it is with current system work, and standby current is very little.
C1, C2, C3 are electric capacity in the circuit, and R1, R2, R3, R4 are resistance, and D is a diode.
