The communication device 200 may include a housing 290, a connector 230, and a control switch 205, and both the connector 230 and the control switch 205 may 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 can be plugged with 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 connection between the 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 connection between the connector and a telephone port in the communication device provided in the embodiment of the present application.

Connector 230 of 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 may refer to the above second pin P2, third pin P3, sixth pin P6, and seventh pin P7.

The detection pin 232 may refer to the first pin P1 and the eighth pin P8 above. 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 disposed at a distance from the circuit board 207. Wherein the distance between the sense pin 232 and the circuit board 207 may be 12 millimeters. 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.

The connection part 2072 is disposed at the other end of the detection pin 232 of the circuit board 207, and copper exposure may be performed at the other end of the circuit board 207 corresponding to the detection pin 232. In order to increase the stability of connection between the other end of the detection pin 232 and the connection part 2071 of the circuit board 207 during the butt, the embodiment of the application may set a bending part 2322 at the other end of the detection pin 232, where the bending part 2322 may generate elastic deformation, and 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 forms a certain interference with the connection part 2072.

When the connector 230 is connected to a port such as the port 600, the common pin 234 and the detection pin 232 are commonly connected to the metal sheet of the port 600 to realize communication between the connector 230 and the port 600, and the metal sheet of the port 600 is pushed down by the detection pin 232 by a distance smaller than the distance between the connection portion 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 2072 of the circuit board 207, and the other end of the detection pin 232 remains 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 piece of the telephone port 800 to realize communication between the connector 230 and the telephone port 800, and the other end of the press-down detecting pin 232 at a position where the metal piece is not arranged of the telephone port 800 abuts against the connecting portion 2072 of the circuit board 207.

It will be appreciated that when the connector 230 is mated with a plug, when both the common pin 234 and the test pin 232 are depressed, and the distance moved by the depressed test pin 232 is less than the distance between the connection 2072 of the circuit board 207 and the other end of the test pin 232, the other end of the test pin 232 is not connected to the connection 2072 of the circuit board 207, and the other end of the test pin 232 remains spaced from the circuit board 207, so that the identification circuit of the communication device 200 can identify the plug as a gateway such as the gateway 600.

It will also be appreciated that when the connector 230 is mated with a plug, the common pin 234 and the test pin 232 are both depressed and the test pin 232 is depressed such that the other end of the test pin 232 is connected to the connection 2072 of the circuit board 207, such that the identification circuit of the communication device 200 can identify the plug as a telephone port such as the telephone port 800.

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

It should be noted that, the distance that the other end of the detection pin 232 is pushed down by the portal 600 in the embodiment of the present application may not be limited to 0.4 mm, such as 0.3 mm or more and 1 mm or less. The distance that the other end of the detection pin 232 is pushed down by the phone port 800 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 detection pin 232 is not damaged.

In order to keep the distance that the other end of the detection pin 232 is pushed down by the mesh 600 to be far smaller than the distance between the other end of the detection pin 232 and the connecting portion 2072, one or two grooves 620 can be formed in the mesh 600, one metal sheet of the mesh 600 can be arranged in one groove 620, the metal sheet located in one groove 620 can be abutted with one detection pin 232, and the other end of the detection pin 232 is pushed down.

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

Fig. 27 is another structural schematic diagram of the connector in the communication device shown in fig. 23. In an alternative embodiment of the present application, the detection pins 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. When the other end of the first pin 232A abuts against one connecting portion 2072 of the circuit board 207 and the other end of the eighth pin 232B abuts against the other connecting portion 2072 of the circuit board 207, the first pin 232A and the eighth pin 232B communicate. The other end of the first pin 232A has a first bending portion 2322A, and the other end of the second pin 232B has a second bending portion 2322B.

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

The identification circuit of the communication device 200 according to the embodiment of the present application may also identify that the connector 230 is plugged into a phone port, such as the phone port 800, when two detection pins 232, such as the first pin 232A and the eighth pin 232B, are in communication.

In an alternative embodiment of the present application, without the need of designing additional detection pins, 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 determine the type of the inserted device, so as to implement two functions. In the embodiment of the present application, when the connector 230 is plugged into a network port, such as the network port 600, it can perform identification through normal polling, and when the connector is plugged into a phone port, such as the phone port 800, two pins, such as the first pin 232A and the eighth pin 232B, are forced to be grounded or both are connected, so as to perform judgment and identification on the plugged signal.

It should be noted that, when the socket such as the socket 600 is plugged into the connector 230, the socket 600 is initially plugged into the connector 230 with the groove 620 avoiding the first pin 232A and the eighth pin 232B, and when the socket 600 is continuously plugged into the socket 600, one spring sheet in the groove 620 contacts one detecting pin 232 such as the first pin 232A in the connector 230, forcing the detecting pin 232 such as the first pin 232A of the connector 230 to elastically deform, and simultaneously pushing down the other ends of the detecting pin 232 such as the first pin 232A and the eighth pin 232B moves downward, i.e. toward the position of the connecting portion 2072, but does not contact the connecting portion 2072 on the circuit board 207, or the copper exposure area. When the portal 600 is fully inserted, the detection pins 232 of the connector 230, such as the first pin 232A and the eighth pin 232B, do not contact the connection 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 phone port such as phone port 800 plug is inserted into connector 230, the PIN of phone port 230, or the metal sheet, has only 6, and the absence of the groove structure at the positions of the detecting PINs 232 such as first PIN 232A and eighth PIN 232B, will cause the detecting PINs 232 such as first PIN 232A and eighth PIN 232B in connector 230 to become more severe, such as depressing the other ends of detecting PINs 232 such as first PIN 232A and eighth PIN 232B down by 1.8 mm, so that the other ends of detecting PINs 232 such as first PIN 232A and eighth PIN 232B abut against connection 2072 of circuit board 207. Further, the detection pin 232 such as the first pin 232A and the eighth pin 232B is distinguished from the state of inserting the network port plug, and it can be recognized that the inserted device is the telephone port plug.

According to the embodiment of the application, the type of the plug can be automatically identified, the plug is adaptively connected according to the identification result, and the situation that the plug cannot be identified due to misplug of a user is avoided.

The metal shell 236 of the connector 230 may carry the structures of the sense pin 232 and the common pin 234.

Referring to fig. 28, fig. 28 is a twenty-first structural diagram of a communication device according to an embodiment of the present application. The communication device 400 may include a first connector 42 that may be plugged into a telephone port, such as an RJ11 telephone port, and a second connector 44 that may be plugged into a network port, such as an RJ 45.

The communication device 200 of fig. 23 of the present embodiment can be selectively plugged into a network port and a telephone port through the connector 230 without requiring additional switching structures. Whereas the communication device 400 shown in fig. 28 requires multiple connectors to achieve mating with the network port and the telephone port. Accordingly, the communication device 200 shown in fig. 23 according to the embodiment of the present application can save the number of connectors and the volume of the communication device 200 compared to the communication device 400 shown in fig. 28.
