[0045] The technical solutions in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0046] In the description of the utility model, it should be understood that the orientation or position relationship indicated by the terms "center", "transverse", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0047] The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature.

[0048] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0049] Currently, handheld mobile communication terminals have various hardware communication interfaces, requiring them to connect to other devices via cables for data communication. For example... Figure 5 As shown, terminal A can connect to the Internet via 4G or 5G, while terminal B does not have a 4G or 5G communication module. Terminal B needs to obtain some data from terminal A via a communication cable, which requires an Internet connection. However, due to security requirements, terminal B cannot directly connect to the Internet and can only obtain data via a cable.

[0050] Communication terminal products come in many models, primarily using serial data communication, with interfaces including but not limited to RS-232, RS-485, RS-422, and OneWire interfaces. For example... Figure 6 As shown, terminal A communicates with terminals B, C, D, or E through the four interfaces described above. Each communication interface requires a dedicated communication cable, resulting in high manufacturing costs. Terminal A also has numerous cable interfaces, making its external structural design difficult. For example... Figure 7 As shown, existing communication cables incorporate four communication interfaces. To accommodate all these interfaces, the cable requires 10 wire cores. This excessive number of cores results in a very thick and bulky cable, making it difficult to carry and costly.

[0051] In addition, each communication interface has a different communication rate, which means that the communication rates of terminal A and the peer terminal B / C / D / E need to be set to be the same for each communication to be able to communicate. This process is complicated and not easy to operate.

[0052] To address the aforementioned problems, this utility model provides a communication cable device that optimizes the cable structure and reduces manufacturing costs.

[0053] like Figure 1and Figure 2 As shown, in one illustrative embodiment of the communication cable device of this utility model, the communication cable device is used for communication between a first terminal 101 and a second terminal 105, including:

[0054] The first plug 102 is connected to the first terminal 101.

[0055] The wire core input terminal 106 is connected to the first plug 102 and includes multiple input wire cores.

[0056] The control unit 103 includes a microcontroller unit chip 201 and a matrix switch switching chip 202. The microcontroller unit chip 201 is connected to the matrix switch switching chip 202 and the input wire. The microcontroller unit chip 201 includes at least two types of communication output interfaces, which are connected to the matrix switch switching chip 202.

[0057] The output terminal 107 is connected to the matrix switch switching chip 202, which includes multiple output wires.

[0058] The second plug 104 is connected to the output wire core at one end and to the second terminal 105 at the other end.

[0059] In the above illustrative embodiment, the first terminal 101 is connected to the input wire core via the first plug 102. The microcontroller unit chip 201 adjusts the switching state of the matrix switch chip 202 according to the received control signal, connecting the specified communication output interface to the appropriate output wire core. In this way, communication data can be transmitted from the first terminal 101 to the second terminal 105 via the input wire core. This improves the flexibility and adjustability of the device. Through the control of the microcontroller unit chip 201, the communication interface can be flexibly configured, supporting different communication protocols and enabling the conversion and selection of multiple communication protocols to adapt to the communication needs between different terminals.

[0060] In some embodiments, the microcontroller unit chip 201 further includes a control pin, which is connected to the matrix switch switching chip 202 and can output a high level or a low level to the matrix switch switching chip 202.

[0061] When the control pin of the microcontroller unit chip 201 is in a high-level or low-level state, the matrix switch switching chip 202 switches according to this signal to control the on / off state of one or more output wires. Different control pin levels further improve the control performance of the device.

[0062] In some embodiments, the control pin includes a first pin 204 and a second pin 205. When the first pin 204 is in either of two voltage levels and the second pin 205 is in either of two voltage levels, the matrix switch switching chip 202 controls one or more output cores in the output terminal 107 of a communication output interface to be turned on.

[0063] Based on the voltage levels of pins 204 and 205, multiple voltage level combinations are generated, corresponding to the conduction or disconnection of multiple output conductors. This allows for more precise control of the output signal path, enabling parallel transmission or independent operation of multiple output conductors to meet various communication modes. By controlling the pins, structural complexity is reduced, resulting in a simpler device structure.

[0064] In some embodiments, the matrix switch switching chip 202 includes multiple switches, and the multiple switches are connected one-to-one with multiple output wires.

[0065] The matrix switcher chip 202 selects the output conductor by controlling multiple switches. When the control pin of the microcontroller unit chip 201 sends a level signal, the matrix switcher chip 202 controls the switching of the switches according to the level signal, thereby selecting the output line of the communication signal. Each output conductor can be controlled independently, thus supporting the switching of multiple communication protocols and meeting the needs of complex communication. The matrix switcher chip 202 can achieve fast switching, ensuring the timeliness and stability of data transmission.

[0066] In some embodiments, the control unit 103 further includes a transmission line 203, one end of which is connected to a communication output interface and the other end of which is connected to a matrix switch switching chip 202.

[0067] Each transmission line 203 carries different communication signals. Through the control of each line by the microcontroller unit chip 201, multiple communication protocols can be transmitted simultaneously. This allows for better adaptation to different types of communication output interfaces, improving communication capabilities and data transmission efficiency.

[0068] In some embodiments, the transmission line 203 includes multiple communication lines, and a communication output interface is connected to one or more communication lines.

[0069] Depending on the type of communication output interface, one or more communication lines can be configured to meet the different requirements of different types of communication output interfaces. Furthermore, it is possible to switch between different communication output interfaces and communication lines between different communication protocols to adapt to various complex communication scenarios.

[0070] In some embodiments, the control unit 103 further includes a grounding line connected to each communication output interface.

[0071] The purpose of grounding lines is to reduce interference caused by signal noise and provide a stable voltage reference, ensuring good transmission quality for each signal output. By suppressing noise interference and ensuring signal purity and stability, signal reliability and communication quality can be improved.

[0072] In some embodiments, such as Figure 3 As shown, the input core includes a power supply core group, which includes a 3.3V core 301 and a GND core 302.

[0073] The power supply core assembly provides power to the inside of the cable to maintain normal operation and improve the stability of the communication cable device.

[0074] In some embodiments, the input conductor further includes a communication conductor group, which includes a 232-TX conductor 303 and a 232-RX conductor 304.

[0075] The function of the communication core group is to transmit information between the microcontroller unit chip 201 and the first terminal 101.

[0076] In some embodiments, the input conductor also includes a wake-up conductor 305.

[0077] The first terminal 101 controls the wake-up wire 305 to wake up the microcontroller unit chip 201 and ensure that the microcontroller unit chip 201 operates normally.

[0078] In practical applications, the first plug 102 connects to the first terminal 101, and the second plug 104 connects to the second terminal 105. The second terminal 105 can be configured as a terminal of different types. The input cores of the communication cable device can be configured with five input cores: two for communication (232-TX core 303 and 232-RX core 304), two for power supply (3.3V core 301 and GND core 302), and one for control wake-up (WAKEUP cable). One end of each of the five input cores is connected to the first plug 102, and the other end is connected to the microcontroller unit chip 201.

[0079] The microcontroller unit chip 201 includes four types of communication output interfaces: RS-232, RS-485, RS-422, and onewire. Different types of communication output interfaces correspond to different types of second terminals 105. The RS-232 interface connects two communication lines. The RS-485 interface connects two communication lines. The RS-422 interface connects four communication lines. The onewire interface connects one communication line. All RS-232, RS-485, RS-422, and onewire interfaces are connected to a ground line.

[0080] like Figure 4 As shown, the output cores of the core output terminal 107 can be configured as core A401, core B402, core C403, core D404 and core E405.

[0081] The first pin 204 of the microcontroller unit chip 201 can be set as GPIO port 1, and the second pin 205 can be set as GPIO port 2.

[0082] When GPIO port 1 is low and GPIO port 2 is low, the matrix switch switching chip 202 controls wire core A401 and wire core B402 to conduct with the RS-232 interface.

[0083] When GPIO port 1 is low and GPIO port 2 is high, the matrix switch switching chip 202 controls the conductors C403 and D404 to conduct through the RS-485 interface.

[0084] When GPIO port 1 is high and GPIO port 2 is low, the matrix switch switching chip 202 controls the wire cores A401, B402, C403 and D404 to conduct with the RS-422 interface.

[0085] When GPIO port 1 is high and GPIO port 2 is high, the matrix switch switching chip 202 controls the E405 core to conduct with the onewire interface.

[0086] During use, after the first plug 102 is connected to the first terminal 101, the 3.3V core 301 and the GND core 302 supply power to the cable. The microcontroller unit chip 201 is powered on, and then initializes the state of the matrix switch switching chip 202, controlling the matrix switch switching chip 202 to sequentially switch cores A401, B402, C403, D404, and E405 to the corresponding connection states of the RS-232 interface, RS-485 interface, RS-422 interface, and onewire interface. Each time a connection is switched, the microcontroller unit chip 201 sends probe command data 5 times in a loop, at a preset communication rate, and the second terminal 105 receives it at the same preset communication rate. After receiving the probe command data, the second terminal 105 parses the first communication rate data within the command data and replies with an acknowledgment command data to the microcontroller unit chip 201 at the preset communication rate. After sending the command, the second terminal 105 adjusts its communication rate to the first communication rate. After receiving the response data, the microcontroller unit chip 201 also adjusts its communication rate to the first communication rate, and the microcontroller unit chip 201 establishes a communication line connection with the second terminal 105.

[0087] After the microcontroller unit chip 201 establishes a communication line connection with the second terminal 105, the microcontroller unit chip 201 sends a connection command message to the first terminal 101. After receiving the message, the first terminal 101 can perform data transmission with the second terminal 105.

[0091] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
