Embodiment
The overall principle of the present invention based in connector to the particular allocation of different pins, these pins are that to implement difference in functionality in the communication terminal (for example radio telephone or PDA) necessary.
Or rather, the present invention proposes: some is used for the pin of a specific function traditionally by especially utilizing change over switch to recombinate, and reduces the quantity of number of connectors and line.
According to a kind of first execution mode (see figure 2) of the present invention, a single connector 21 (for example in radio telephone) allows to insert some function, wherein (does not all list):
-data download in the RS232 connection;
-data download in the USB connection;

Especially, connector 21 is connected on module 23, some output audio circuits 24 and some the input voice band lines 25 of an assurance radio telephone basic function (especially signal processing) by a change over switch SWITCH22.
According to this first execution mode of the present invention, recombinated and implemented the required different pins of this class function, so that obtain a connector that includes only 11 pins.
For the quantity of the pin that reduces connector, the present invention especially propose multiplexing some implement the pin of difference in functionality, such as one to USB interface, to transfer of data/download cable, to the connection of earphone and/or microphone.
Note this multiplexing be not conspicuous because some signal can not be re-used because of high electric current.In addition, the pin of traditional connector is provided with the electric current of 250mA usually, and usb signal then needs the electric current of 500mA.
Therefore, we provide a list, and this table has been showed the different pins that are used for these functions, and according to their prescribed use at one according to the reorganization on 11 pins of connector of the present invention.
| Pin | Transmission/download function | The USB function | Ear-phone function | Could be multiplexing? | |
| 1 | VBATT | Not | |||
| 2 | VBATT | Not | |||
| 3 | CHG_IN | VBUS | Not | ||
| 4 | CHG_IN | Not | |||
| 5 | RTS | HPL | Be | ||
| 6 | CTS | HPR | Be | ||
| 7 | RXD | | HPCM | Be | |
| 8 | TXD | D- | | Be | |
| 9 | ADT/BOOT | ID | HEAD_DETECT | Not | |
| 10 | GND | Not | |||
| 11 | GND | Not |
The function of these different pins has been defined with reference to Figure 1A and 1B (being used to illustrate prior art) in preamble.
Therefore, first group of pin especially comprises the pin 5,6,7,8 that is connected to a change over switch 22, and this change over switch allows in these pins each is linked to each other with wireless telephonic signal.
-the second group of pin, this group pin comprise the pin one and 2 that is defined as to an output voltage V BATT of radio telephone transmission;
Three groups of pins of-Di, this group pin comprises the pin one 0 and 11 that is defined as ground connection;
Four groups of pins of-Di, this group pin comprise the pin 3 and 4 that is defined as to a radio telephone transmission input voltage (waking up) CHG_IN-VBUS;
Five groups of pins of-Di, this group pin comprise the pin 9 that is defined as detection ancillary equipment.
Therefore, change over switch 22 allows and will reach the signal multiplexing that transmits on transfer of data/download cable on audio signal and the USB cable, and these multiplexed signalss come from the pin 5,6,7,8 of first group of pin.
This change over switch for example is the STG3699 of ST Micro Electronic (registered trade mark, ST microelectronics) company.
Can notice that being connected between pin RXD and TXD (being implemented in transfer of data/download cable transmitting data) and pin D+ and the D-(being implemented in the USB cable transmitting data) is not apparent, but need add the resistance of one 100 Ω between pin RXD and the pin D+, the resistance of one 100 Ω of interpolation between pin TXD and pin D-.
Four pins of RTS/CTS/RXD/TXD also are connected to module 23 by the resistance of four 100 Ω.
Fig. 3 is illustrated as reference, and pin RXD/TXD can be counted as wireless telephonic I/O (GPIO, English " General Purpose Input/Output ", i.e. " general input and output ").
Especially can use this GPIO mode to come emulation I2C bus (SDA/SCL, English " serial data/serial clock ", i.e. " serial data/serial clock ").So, should be by adopting " on draw " resistance 31 (this resistance is added to a USB protection module 32) simulate signal SDA on line D+ of a 1.5K Ω.
As described in Fig. 4, module 23 has two signal ADT and BOOT by a plurality of resistance, makes pin BOOT and the ADT that allows the serial communication of transfer of data and download in the combination of connector 21 places.
Therefore, download (BOOT mode) for implementation procedure on radio telephone, the value of resistance R 41 (directly being connected on the output ADT of module 23) should be lower than 5K Ω.
If the value of resistance R is higher than 5K Ω, just can detect the ancillary equipment that is connected on the connector 21.
Therefore, for example:
If-R=1K is Ω, just detect be connected (before the radio telephone start) with a download cable;
If-R=15K is Ω, just detect be connected (needing radio telephone to be in open state) with a data cable;
If-R=2.2K is Ω, this value is corresponding with the internal resistance of microphone, so detect after radio telephone start and being connected an of earphone;
If-R=10K is Ω, just detect be connected (no matter radio telephone is start or off-mode) with a charger;
If-R=56K is Ω, just detect and being connected an of USB cable.
Therefore, the value of resistance R allows to select BOOT mode or ADT mode.Therefore module 23 preferably includes the device that some measure the value of the resistance R on the present branch road ADT, and a kind of connection type is associated with a given resistance value.
According to the present invention, it seems that better scheme is first enforcement of downloading mode (mode BOOT) because or even during radio telephone shutdown downloading mode also in operation.
For this reason, just enough as long as observe the control logic of change over switch 22.Therefore, if selected change over switch 22 is STG3699 type (registered trade mark), the pin IN of this change over switch should be in low state, and passes through pull down resistor 26 ground connection of a 100K Ω.This resistance is particularly useful for an invalid line-to-ground.
In addition, according to prior art, the GPIO interface of a special use of use detects the existence of earphone and/or microphone.
According to the present invention, interface GPIO27 directly allows control transformation switch 22.
Now, with reference to Fig. 5 second execution mode according to a single connector 51 of the present invention is described.
This second execution mode especially allows by using a connector that can stand high electric current further to reduce the quantity of the connection of connector 51.
Especially, in electronic circuit 57, this connector 51 is connected to a module 52, some output audio circuits 24, some input voice band line 25 and test sections 53 by a transfer switch SWITCH54.
According to this execution mode, connector 51 comprises 5 pins:
-the first pin 3 allows toward conversion transfer switch 54 input/output signal HPCM, CHG-_IN, VBUS;
-the second pin 7 is connected to change over switch 54, allows input/output signal HPR and D+;
-Di three-prong 8 is connected to change over switch 54, allows input/output signal HPL and D-;
-Di four pins 9 also are connected to change over switch 54, allow input/output signal MIX_EXT, ID, ADT;
-last pin one 0, ground connection GND.
Especially, change over switch 54 allows audio signal and reaching the signal multiplexing that transmits on the USB cable on transfer of data/download cable, and these signals come from the pin 3,7,8,9 of connector 51.
According to this second execution mode, electronic circuit 57 (for example printed circuit) comprises a test section 53, comprises access point (test point) or any one connector.
And signal VBATT is used for from connector 51 open wireless phones, if used battery, if perhaps on the electronic circuit test point is arranged, this signal VBATT just needn't be connected on the connector 51.
Therefore, can add a plurality of test points in test section 53, mainly be to download in order to connect (RTS, CTS, RXD, TXD) by RS232; Can also use to connect D+ and D-, so that in connector 51 transmission data.
On supporting, terminal under a kind of situation of mode, can also add a USB connecting line, so that transmission data and download.
Example shown in Fig. 5 especially by use a USBmini B (2.0 or OTG) type, support the connector of about 1A electric current to implement the present invention.This connector especially with USB otg standard compatibility.
The improvement of setting forth implementing first execution mode (for example Fig. 3 and Fig. 4) also can be applied to this second execution mode.
Therefore, electronic circuit 57 allows to use connector 51 that includes only 5 pins, works with change over switch 54 (for example USB type).
Therefore; the present invention allows to reduce connecting line and used number of connectors; because the present invention needn't use audio signal special connector (socket connector), EMI (English " Elctro-Magnetic Immunity ", " electromagnetism is anti-interference ") filter (can protective circuit be not subjected to electromagnetic interference), is used for the ESD-diode of earphone (can protective circuit not influenced by electrostatic discharge) ...
Therefore, have benefited from a circuit according to the invention owing to reduce that connecting line quantity on the connector produces in the better resisting interference aspect electrostatic discharge (ESD) or the electromagnetism (EMI).
Under the situation of using difference input and output audio signal, the present invention especially allows better radio frequency anti-interference.
Set forth a kind of enforcement modification referring now to Fig. 6, in this modification, for downloading mode has used multiplexing usb bus.
Available in the BOOT mode to RS232 communication, and, use the input/output signal in the RS232 type communication to download starting (" boot ", i.e. " guiding ") code under the disabled situation of usb communication mode, this starting code has comprised the USB driving.Enter usb communication then, so that benefit from a download very at a high speed, about 12Mbit/s.
This modification is based on a cable of use and a simple microcontroller, and this microcontroller allows to come emulation RS232 connection by usb protocol, and allows to connect switching from trend USB after the download of guiding (boot) code finishes.
Therefore, the present invention has many advantages, and has realized combination simulation and/or signal numeral, different capacity by a change over switch.
Refer again to Fig. 7 A and 7B illustrate according to prior art (7A) and according to the present invention the electronic circuit of employing in the radio telephone of (7B) (when adopting second execution mode).
Therefore, in Fig. 7 A, connector comprises 18 pins, must adopt an electromagnetic interface filter.This filter is exactly the circuit that can remove interfering frequency, only allow useful frequency pass through.
In Fig. 7 B, 18 pin connectors are by one 5 pin connector (for example USBmini category-B type) replacement, and filter EMI is cancelled, and has added a change over switch.Can notice: the change over switch open circuit, interfering frequency can not be passed through.For downloading mode, can also adopt the multiplexing USB bus.
Especially can notice: can reduce the area of electronic circuit according to solution of the present invention, thereby can for example reduce to resemble the size of the such terminal of radio telephone, PDA or any other mobile communication facility, or add new function.
Therefore, the present invention allows to develop simpler, area occupied electronic circuit still less.
