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 sensing pin P9 may be located outside the first multiplexing pin P4 and the second multiplexing pin P5. It is understood that the size of the network port, such as RJ45 network port, and the size of the telephone port, such as RJ11 telephone port, are different, such as the size of the network port is larger than the size of the telephone port, and when the telephone port is plugged into the connector 230, a gap can be formed between the connector 230 and the telephone port, and the embodiment of the present application can dispose the test pin P9 at the gap position between the connector 230 and the telephone port, or when the telephone port is inserted into the connector 230, the telephone port is spaced from the test pin P9, and the test pin P9 has a voltage value, such as the second voltage value. When the socket is inserted into the connector 230, the test pin P9 is pressed, so that the test pin P9 is deformed, and the test pin P9 also has a voltage value, such as the first voltage value.

The first voltage value and the second voltage value are different in the embodiment of the application.

In some embodiments, when the network port is connected to the connector 230, the detection pin P9 is pressed by the network port to be grounded, and the first voltage value of the detection pin P9 is zero. When the phone port is connected to the connector, the test pin P9 is always spaced apart from the phone port, and the second voltage value of the test pin P9 is greater than zero. Therefore, the embodiment of the present application may determine that the connector 230 is connected to the network port when the voltage value detected by the detection pin P9 is zero, and may determine that the connector 230 is connected to the telephone when the voltage value detected by the detection pin P9 is a second voltage value greater than zero.

Note that, when the connector 230 is in an idle state, that is, when the connector 230 is not connected to the network port or the telephone port, the detection pin P9 may detect the second voltage value greater than zero, and at this time, the second voltage value may be maintained to be connected to the second circuit 220 through the connector 230.

Referring to fig. 19, fig. 19 is a seventeenth structural schematic diagram of a communication device according to an embodiment of the present application. 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. 20 to fig. 22, fig. 20 is a schematic structural diagram of a connector in the communication device shown in fig. 19, fig. 21 is a schematic diagram of a connector and a network port in the communication device according to the embodiment of the present application, and fig. 22 is a schematic diagram of a connector and a telephone port in the communication device according to 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 a circuit board (shown in the figure) 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 270 of the communication device 200, and the other end is spaced apart from the metal shell 236 of the connector 230. It should be noted that the circuit board is connected to the metal shell 236, the metal shell 236 can be connected to the ground of the circuit board, and the metal shell 236 can not only carry the detection pin 232 and the common pin 234, but also can play a role of shielding.

When the connector 230 is connected to a net port such as the net port 600, the common pin 234 is connected to a metal plate of the net port 600 to communicate the connector 230 with the net port 600, and the metal plate of the net port 600 presses the detection pin 232 so that the other end of the detection pin 232 abuts against the metal shell 236 of the connector 230. The sense pin 232 may thus be connected to a circuit board through the metal shell 236, such as the sense pin 232 being grounded.

When the connector 230 is connected to a telephone port such as the telephone port 800, the common pin 234 is connected to a metal plate of the telephone port 800 to communicate the connector 230 with the telephone port 800, and the other end of the telephone port 800 not pressing the detection pin 232 causes the detection pin 232 to be spaced apart from the metal shell 236, or the telephone port 800 presses the detection pin 232 by a distance smaller than the distance between the other end of the detection pin 232 and the metal shell 236.

In the embodiment of the present application, there may be one or more detection pins 232. When the detection pin 232 is one, and when the net mouth side presses the other end of the detection pin 232, the detection pin 232 is pressed to the position of the metal shell 236 and abuts against the metal shell 236, and the detection pin 232 can be connected to the ground of the circuit board through the metal shell 236.

The other end near the detection pin 232 is located on the inner surface of the metal case 236, and when the detection pin 232 is pressed sideways, the detection pin 232 can be driven to abut against the inner surface of the metal case 236. The connector 230 of the embodiment of the present invention may further include a metal spring 238, and the metal spring 238 may be disposed outside the detection pin 232. When the net port is inserted into the connector 230, the net port abuts against the metal elastic sheet 238, and drives the metal elastic sheet 238 to move, so that the metal elastic sheet 238 abuts against the other end of the detection pin 232, and further drives the detection pin 232 to abut against the inner surface of the metal shell 236.

It will be appreciated that when the connector 230 is mated with a plug, the connection of the connector 230 to the network port is recognized when the male pin 234 is depressed and the other end of the detection pin 232 is pressed into abutment with the metal shell 236.

It is also understood that when the connector 230 is mated with a plug, the connector 230 is recognized as being connected to the telephone port when the common pins 234 are all pressed down and the other end of the detection pin 232 is not pressed sideways and is not abutted against the metal shell 236, or the other end of the detection pin 232 is pressed sideways and is not abutted against the metal shell 236.

The following description will take two detection pins 232 as an example.

For example, the detection pins 232 may include a first pin 232A and an eighth pin 232B, with the common pin 234 being located between the first pin 232A and the eighth pin 232B. For example, when the connector 230 is not plugged into a plug, it can be understood that the common pin 234 is not pressed, and the other ends of the first pin 232A and the eighth pin 232B are not pressed, and are spaced from the inner surface of the metal shell 236. When the connector 230 is plugged into the net port 600, the net port 600 presses the first pin 232A and the eighth pin 232B, so that the other end of the first pin 232A abuts against one side of the metal shell 236, such as the first side 236A, specifically, the other end of the first pin 232A abuts against the inner surface of the first side 236A. While the other end of the eighth pin 232B is brought into abutment with another side of the metal shell 236, such as the second side 236B, which can be particularly understood as the other end of the eighth pin 232B is brought into abutment with the inner surface of the second side 236B. The first pin 232A and the eighth pin 232B may be both connected to the ground of the circuit board, and the identification circuit of the communication device may identify that the net-port 600 is connected to the connector 230 according to the ground of the first pin 232A and the eighth pin 232B. It is understood that the first pin 232A and the eighth pin 232B can also communicate through connection with the circuit board, and the identification circuit of the communication device can further identify that the net-port 600 is connected with the connector 230 according to the first pin 232A and the eighth pin 232B.

When the connector 230 is plugged into the phone port 800, the phone port 800 does not press the first pin 232A and the eighth pin 232B, so that the other end of the first pin 232A is spaced from one side of the metal shell 236, such as the first side 236A, which can be specifically understood as the other end of the first pin 232A is spaced from the inner surface of the first side 236A. While the other end of the eighth pin 232B is spaced from another side of the metal shell 236, such as the second side 236B, which can be particularly understood as the other end of the eighth pin 232B is spaced from the inner surface of the second side 236B. Wherein the width of the phone port 800 may be 9.7 mm, the embodiment of the present application may set the widths of the first detection pin 232A and the second detection pin 232B to be greater than 9.7 mm. Of course, the width of the first pin 232A and the eighth pin 232B may be set to be slightly less than or equal to 9.7 mm. It is ensured that the other ends of the first pin 232A and the eighth pin 232B are spaced apart from the metal case 236 when the phone port 800 is connected to the connector 230. The identification circuit of the communication device may identify that the phone port 800 is connected to the connector 230 according to the first pin 232A and the eighth pin 232B being ungrounded or connected.

The other end of the first lead 232A has a first bending portion 2322A, and the other end of the eighth lead 232B has a second bending portion 2322B. The first bent portion 2322A and the second bent portion 2322B may both generate elastic deformation, so as to increase the stability of the metal shell 236 in abutting connection. The first metal elastic piece 238A is disposed on the outer side of the first bent portion 2322A, and the second metal elastic piece 238B is disposed on the outer side of the second bent portion 2322B.

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 telephone port such as the telephone port 800, 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 an internet port such as the internet port 600 is inserted.

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 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. 19 of the present embodiment 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. 23 requires multiple connectors to interface with the internet and telephone ports. Therefore, the communication device 200 shown in fig. 19 can save the number of connectors and the volume of the communication device 200 compared with the communication device 400 shown in fig. 23 in the embodiment of the present application.
