When the test pin P9 tests that the connector 230 is connected to the telephone port, i.e. when the test result of the test pin P9 is that the connector 230 is connected to the telephone port, the processor 240 controls the first input terminal a1 to be connected to the third output terminal B3 and the second input terminal a2 to be connected to the fourth output terminal B4.

The communication device 200 can include a housing 290, a connector 230, and a control switch 205, both the connector 230 and the control switch 205 can be disposed on the housing 290. It should be noted that the housing 290 may also carry other components of the communication device 200, such as an antenna structure. The connector 230 can be plugged with a telephone port such as an RJ11 telephone port, or a network port such as an RJ45, and can be matched according to actual requirements.

Referring to fig. 24 to 26, fig. 24 is a schematic structural diagram of a connector in the communication device shown in fig. 23, fig. 25 is a schematic structural diagram of a connector and a network port in the communication device provided in the embodiment of the present application, and fig. 26 is a schematic structural diagram of a connector and a telephone port in the communication device provided in the embodiment of the present application.

The connector 230 of the communication device 200 may include a common pin 234 and a detection pin 232. The common pin 234 is fixedly connected to the circuit board 207 of the communication device 200, and the common pin 234 can refer to the second pin P2, the third pin P3, the sixth pin P6, and the seventh pin P7.

The detection pin 232 can refer to the first pin P1 and the eighth pin P8. The detection pin 232 is different from the first pin P1 and the eighth pin P8 in that one end of the detection pin 232 is fixedly connected to the circuit board 207 of the communication device 200, and the other end is spaced apart from the circuit board 207. Wherein the distance between the detection pin 232 and the circuit board 207 may be 12 mm. It should be noted that the distance between the detection pin 232 and the circuit board 207 is not limited to 12 mm, such as 13 mm, 11 mm, 15 mm, and the like.

It should be noted that the circuit board 207 is disposed with the connecting portion 2072 at the other end position of the detection pin 232, and copper exposure can be performed at the other end position of the circuit board 207 corresponding to the detection pin 232. In order to increase the stability of the other end of the detection pin 232 and the connection part 2071 of the circuit board 207 being connected when abutting, in the embodiment of the present application, the other end of the detection pin 232 may be provided with the bending part 2322, the bending part 2322 may generate elastic deformation, when the other end of the detection pin 232 abuts against the connection part 2072, the other end of the detection pin 232 may be continuously pressed down, so that the bending part 2322 of the detection pin 232 generates deformation, and a certain interference amount is formed between the other end of the detection pin 232 and the connection part 2072.

When the connector 230 is connected to a network port such as the network port 600, the common pin 234 and the detection pin 232 are connected to the metal sheet of the network port 600 together to communicate the connector 230 with the network port 600, and the distance moved by the metal sheet of the network port 600 pressing down the detection pin 232 is smaller than the distance between the connection part of the circuit board 207 and the other end of the detection pin 232. That is, when the connector 230 is connected to the portal 600, the other end of the detection pin 232 is not connected to the connection part 2072 of the circuit board 207, and the other end of the detection pin 232 is kept spaced apart from the circuit board 207.

When the connector 230 is connected to a telephone port such as the telephone port 800, the common pin 234 is connected to the metal plate of the telephone port 800 to communicate the connector 230 with the telephone port 800, and the other end of the position depression detection pin 232 of the telephone port 800 where the metal plate is not disposed abuts against the connection part 2072 of the circuit board 207.

It is to be understood that, when the connector 230 is in plug-fit engagement with a plug, when the common pin 234 and the detection pin 232 are both pressed down and the distance by which the pressing-down detection pin 232 moves is smaller than the distance between the connection part 2072 of the circuit board 207 and the other end of the detection pin 232, the other end of the detection pin 232 is not connected to the connection part 2072 of the circuit board 207, and the other end of the detection pin 232 is kept spaced from the circuit board 207, so that the identification circuit of the communication device 200 can identify the plug as a net port such as the net port 600.

It is also understood that when the connector 230 is mated with a plug, the common pin 234 and the detection pin 232 are both pressed down, and the detection pin 232 is pressed down so that the other end of the detection pin 232 is connected to the connection portion 2072 of the circuit board 207, so that the identification circuit of the communication apparatus 200 can recognize that the plug is a telephone port such as the telephone port 800.

For example, when the connector 230 is not plugged into a plug, it can be understood that when neither the detection pin 232 nor the common pin 234 is pressed, the distance between the other end of the detection pin 232 and the connection portion 2072 of the circuit board 207 may be 12 mm. When the connector 230 is plugged into the socket 600, the socket 600 can press the other end of the detection pin 232 to move 0.4 mm, so that the other end of the detection pin 232 and the connection part 2072 still keep an increased distance of 0.8 mm, and the other end of the detection pin 232 can be ensured to be spaced from the connection part 2072 without contacting. In turn, the portal 600 may be connected together to communicate with the connector 230 via the common pin 234 and the detection pin 232. When the connector 230 is plugged into the phone port 800, the phone port 800 may push the other end of the detection pin 232 to move 1.8 mm, so that the other end of the detection pin 232 has a large interference with the connection part 2072, and a stable connection can be maintained.

It should be noted that, in the embodiment of the present application, the distance that the other end of the mesh opening 600 presses the detection pin 232 may not be limited to 0.4 mm, such as greater than or equal to 0.3 mm, and less than or equal to 1 mm. The distance that the other end of the detection pin 232 is pushed down by the phone port 800 in the embodiment of the present application may not be limited to 1.8 mm, as long as the distance that the other end of the detection pin 232 is pushed down by the phone port 800 is greater than 1.2 mm, and the other end of the detection pin 232 is not damaged.

In order to keep the net mouth 600 to press down the distance that the other end of the detection pin 232 moves to be far less than the distance between the other end of the detection pin 232 and the connecting part 2072, in the embodiment of the present application, one or two grooves 620 may be formed in the net mouth 600, one metal sheet of the net mouth 600 may be disposed in one groove 620, and the metal sheet located in one groove 620 may abut against one detection pin 232 to press down the other end of the detection pin 232.

In an alternative embodiment of the present application, when the other end of the detection pin 232 abuts against the connection portion 2072 of the circuit board 207, the other end of the detection pin 232 is grounded.

Fig. 27 is another schematic diagram of the connector of the communication device of fig. 23. In an alternative embodiment of the present application, the detection pin may include a first pin 232A and an eighth pin 232B, and the common pin 234 is located between the first pin 232A and the eighth pin 232B. When the other end of the first pin 232A abuts against one of the connection parts 2072 of the circuit board 207 and the other end of the eighth pin 232B abuts against the other connection part 2072 of the circuit board 207, the first pin 232A and the eighth pin 232B communicate. The other end of the first lead 232A has a first bending portion 2322A, and the other end of the second lead 232B has a second bending portion 2322B.

The identification circuit of the communication device 200 of the present embodiment can also identify that the connector 230 is plugged into a telephone port, such as the telephone port 800, when one or both of the detection pins 232 are grounded.

The identification circuit of the communication device 200 of the embodiment of the present application can also identify that the connector 230 is plugged with a telephone port such as the telephone port 800 when the two detection pins 232, such as the first pin 232A and the eighth pin 232B, are connected.

In an optional embodiment of the present application, under the condition that no additional detection pin is required, eight pins of the connector 230 may be used to be compatible with a phone port such as the phone port 800 and a network port such as the network port 600, and the type of the inserted device may be determined to implement two functions. The embodiment of the present application can perform identification by normal polling when the connector 230 is inserted into a network port such as the network port 600, and perform judgment and identification on an insertion signal when two pins such as the first pin 232A and the eighth pin 232B are forced to be grounded or both are connected when a telephone port such as the telephone port 800 is inserted.

It should be noted that, when a net port such as a plug of the net port 600 is inserted into the connector 230, the groove 620 is located at the position of the net port 600 to avoid the first pin 232A and the eighth pin 232B in the initial insertion stage, and when the net port 600 is continuously inserted, one elastic piece in the groove 620 contacts one detection pin 232 such as the third pin 232A in the connector 230, so as to force the detection pin such as the first pin 232A of the connector 230 to be elastically deformed, and at the same time, the other end of the detection pin 232 such as the first pin 232A and the eighth pin 232B is pressed down, i.e., moves toward the position of the connection part 2072, but does not contact the connection part 2072 on the circuit board 207, or the copper exposed area. When the portal 600 is completely inserted, the detection pins 232 such as the first pin 232A and the eighth pin 232B of the connector 230 do not contact the connection part 2072 on the circuit board 207, and can be normally recognized by the common pin 234, the detection pins 232 such as the first pin 232A and the eighth pin 232B.

When a telephone port such as the telephone port 800 is plugged into the connector 230, the PIN PINs, or the metal sheets, of the telephone port 230 are only 6, and there is no groove structure at the positions of the detection PINs 232 such as the first PIN 232A and the eighth PIN 232B, which may cause the detection PINs 232 such as the first PIN 232A and the eighth PIN 232B in the connector 230 to be more sharply phased, such as pressing down the other ends of the detection PINs 232 such as the first PIN 232A and the eighth PIN 232B by 1.8 mm, so that the other ends of the detection PINs 232 such as the first PIN 232A and the eighth PIN 232B abut against the connecting part 2072 of the circuit board 207. Further, the detection pins 232 such as the first pin 232A and the eighth pin 232B are distinguished from the state of being inserted into the network port plug, and it can be recognized that the inserted device is a telephone port plug.

According to the embodiment of the application, the type of the plug can be identified autonomously, self-adaption switching-on is carried out according to the identification result, and the condition that the user cannot identify the plug due to wrong plug insertion is avoided.

The metal shell 236 of the connector 230 may carry the sensing pin 232 and the common pin 234, among other structures.

Referring to fig. 28, fig. 28 is a schematic diagram of a twenty-first structure of a communication device according to an embodiment of the present application. The communication device 400 may include a first connector 42 and a second connector 44, the first connector 42 being mateable with a telephone port, such as an RJ11 telephone port, and the second connector 44 being mateable with a network port, such as an RJ 45.

The communication device 200 shown in fig. 23 can be selectively plugged into the internet port and the telephone port through the connector 230 without additional switching structures. Whereas the communication device 400 shown in fig. 28 requires multiple connectors to interface with the internet and telephone ports. Therefore, the communication device 200 shown in fig. 23 can save the number of connectors and the volume of the communication device 200 compared with the communication device 400 shown in fig. 28 in the embodiment of the present application.
