Abstract
The utility model discloses a multifunction mobile phone data wire with toggle switch comprising a direct-communication USB circuit, a USB-RS232C conversion circuit, a toggle switch SW701, a conversion chip U701, PC ports J702 and Mini_USB mobile phone ports J701. The toggle switch(SW701)can be set to ''0'' or ''1'', when the toggle switch SW701 is set to ''0'', the mobile phone data wire is in the work state of the USB-RS232C conversion circuit; when the toggle switch SW701 is set to ''1'', the mobile phone data wire is in the work state of the direct-communication USB circuit. Because a toggle switch is added on the circuit of mobile phone data wire, the utility model gets the function of that one data wire can possess two functions of the real conversion of USB and RS232 to USB, so the cost is reduced.
Description
Technical field
The utility model relates to a kind of cellular phone data line, relates in particular to a kind of multi-functional mobile phone data line with toggle switch.
Background technology
Cellular phone data line has become the annex of a lot of model mobile phone indispensabilities at present, and a lot of brands claim that all the cellular phone data line of oneself is to support the USB standard, but from technological layer, if cellular phone data line will really meet current USB standard, just need two cellular phone data lines (USB Cable), one is the data line that really meets current USB standard, also have one then to be that RS232 (the RS-232 communication port that refers to communication function on the mobile phone) changes USB, use inconvenience and can raise cost but will bring like this.
The utility model content
The technical problems to be solved in the utility model provides a kind of multi-functional mobile phone data line with toggle switch, can realize two kinds of communication functions.
For solving the problems of the technologies described above, a kind of multi-functional mobile phone data line circuit with toggle switch of the utility model comprises USB direct circuit, USB and RS232 change-over circuit, toggle switch SW701, conversion chip U701, pc port J702 and Mini_USB mobile phone port J701; Toggle switch (SW701) can put 0 or 1, and when putting 0 when toggle switch SW701, cellular phone data line is USB and RS232 change-over circuit duty; When described toggle switch SW701 put 1, cellular phone data line was a USB direct circuit duty.
The utility model is that real USB and RS232 changes USB owing to adding that on the data in mobile phone line circuit toggle switch, a data lines can reach two kinds of functions, thereby has reduced cost.
Description of drawings
Fig. 1 is the circuit of the multi-functional mobile phone data line of the utility model band toggle switch.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Use in the data line communication process at mobile phone, mainly exist two kinds of communication relations:
1, USB＜---→ USB, be mainly used in the quick transmission that realizes mass data, as the image photograph of MP3,1,000,000 strokes of elements etc.;
2, USB＜---→ RS232, be mainly used in mobile phone signal calibration, software version updating, data sync, mobile phone and make modulator-demodular unit etc.
As shown in Figure 1, be the circuit of the multi-functional mobile phone data line of the utility model band toggle switch, this circuit mainly is made up of USB direct circuit, USB and RS232 change-over circuit two large divisions; Its circuit theory is as follows:
1. work as toggle switch SW701 and be in 0 state, when promptly data line (Cable) is operated in USB and RS232 change-over circuit.This moment, the V_BUS power supply of PC and usb data signal were inserted by 1 pin of J702 (pc port) and 2 pin, 3 pin respectively, cut to its 8 pin and 5 pin, the output of 13 pin through toggle switch SW701; The V_IN power supply of 8 pin is given conversion chip U701 power supply.The usb data of 5 pin, 13 pin is introduced by 4 pin and 5 pin of U701, and portion deciphers and compiles within it, is sent with the form of RS232 by 25 pin and 26 pin again; Insert J701 (Mini_USB mobile phone port) through SW701.Notice that this moment, 4 pin (ID Pin) of mobile phone end Mini_USB mouth were cut the pull down resistor to 33K through SW701, mobile phone just can have been discerned this Cable like this, thereby usb signal just can (RX TX) have carried out data transmission with the RS232 signal.
2, be in 1 state as toggle switch sw701, when promptly Cable is operated in the USB direct circuit.This moment, the V_BUS power supply of PC and usb data signal were inserted by 1 pin of J702 and 2 pin, 3 pin respectively, cut to its 9 pin and 6 pin, the output of 14 pin through toggle switch SW701; The 5V power supply of 9 pin is directly linked 1 pin of J701; 6 pin, 14 pin insert J701 (Mini_USB port) through SW701 again.This moment, 4 pin (ID Pin) of mobile phone end Mini_USB mouth were unsettled.This moment, Cable was the USB direct-through line.
In sum, the multi-functional mobile phone data line of band toggle switch of the present utility model can be realized two kinds of functions, and two parts circuit is independent fully under duty separately, does not have any signal interference.Thereby can guarantee that data transmission safety is with stable.
