[0047] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0048] Please see Figure 1 and Figure 2 The multi-functional data cable also includes:
[0049] The splitter control box 700 houses the fast charging interface 300, the data interface 400, and the integrated circuit board 500. The terminal connector 100 and the audio / video connector 200 are connected to the splitter control box 700 via the cable body 800. Specifically, the splitter control box 700 is an independent module located in the middle of the data cable or near the terminal connector 100. By concentrating the fast charging interface 300, the data interface 400, and the integrated circuit board 500 together, the splitter control box 700 effectively reduces stress concentration inside the cable body 800, lowers the risk of damage to the cable body 800, improves the structural stability and durability of the data cable, and makes cable body 800 management more convenient and its use more flexible.
[0050] Please see Figures 2 to 5 The splitter control box 700 includes: a housing 710, a receiving cavity 720 inside the housing 710, a fast charging interface 300, a data interface 400 and an integrated circuit board 500 are all located inside the receiving cavity 720, and a connection through hole 711 is provided in the housing 710 corresponding to the positions of the fast charging interface 300 and the data interface 400. Specifically, the housing 710 is typically made of high-strength, wear-resistant engineering plastics (such as ABS, PC) or metal materials (such as aluminum alloy) to ensure good mechanical strength and durability. The receiving cavity 720 is the space inside the housing 710, used to install and fix key components such as the fast charging interface 300, data interface 400, and integrated circuit board 500. The connecting through hole 711 is a hole opened on the housing 710 for connecting the terminal connector 100 and the audio / video connector 200. The terminal connector 100 and the audio / video connector 200 are connected to the housing 710 through the cable 800. The cable 800 can use a highly conductive copper core, covered with a shielding layer and an insulation layer to ensure the stability of signal transmission and anti-interference capability.
[0051] Please see Figures 2 to 5 The housing 710 has a through channel 730. A first cover 740 and a second cover 750 are located at the two ends of the channel 730. The portion of the channel 730 between the first cover 740 and the second cover 750 forms a receiving cavity 720. Both the first cover 740 and the second cover 750 have threading holes 751 for the thread 800 to pass through. Specifically, the channel 730 can extend through the entire length or part of the length of the housing 710. The first cover 740 and the second cover 750 are located at the two ends of the channel 730, respectively, to close the two ends of the channel 730, forming a closed space, i.e., the receiving cavity 720. Both the first cover 740 and the second cover 750 have threading holes 751 for the thread 800 to pass through. The size and shape of the holes should match the diameter of the thread 800 to ensure that the thread 800 can pass through smoothly. The first cover 740 and the second cover 750 can be fixed to the housing 710 by screws or clips.
[0052] Preferably, the first cover 740 and the second cover 750 are interference-fitted with the housing 710. It is understood that an interference fit connection refers to a connection where, during assembly, one part is slightly larger than another, and they are assembled together by external force to form a tight connection. In the distribution control box 700, the first cover 740 and the second cover 750 are interference-fitted with the housing 710, ensuring the tightness and stability between the first cover 740 and the second cover 750 and the housing 710. The interference fit provides a good seal, preventing dust, moisture, etc., from entering the interior of the housing 710. Interference fits typically eliminate the need for screws, clips, or other fasteners, simplifying the design and manufacturing process. More specifically, the outer diameter of the first cover 740 and the second cover 750 needs to be slightly larger than the inner diameter of the corresponding opening on the housing 710, or one or more protrusions are designed on the outer edge of the first cover 740 and the second cover 750. These protrusions are slightly larger than the inner diameter of the corresponding opening on the housing 710 to form an interference fit. The protrusions, the first cover 740, the second cover 750, or the housing 710 are usually made of a material with a certain degree of elasticity, such as engineering plastics (e.g., ABS, PC) or rubber.
[0053] Please see Figure 3 The first cover 740 and the second cover 750 are provided with slots 752 for securing the integrated circuit board 500. Specifically, the slots 752 can be located inside the first cover 740 and the second cover 750, along the edge of the cover or at a specific position. The main function of the slots 752 is to fix the integrated circuit board 500, ensuring that it does not move or shift within the distribution control box 700. The shape of the slots 752 can match the edge of the integrated circuit board 500 to ensure precise positioning and a secure connection. Common shapes include rectangles, trapezoids, or bevels with a certain angle. The size of the slots 752 can be slightly smaller than the thickness of the integrated circuit board 500 to form an interference fit, thereby achieving a secure connection. The slots 752 are usually made of materials with a certain degree of elasticity, such as engineering plastics (e.g., ABS, PC) or rubber, to facilitate the insertion and removal of the integrated circuit board 500.

[0061] More specifically, data enters the control circuit 600 from the terminal connector 100. First, the communication protocol module 630 identifies the communication protocol and converts it into a protocol suitable for data transmission. The signal conversion module 620 converts the data signal into a format suitable for peripherals or displays to receive. The converted data is then output to the peripheral or display through the data interface 400 or the audio / video connector 200. Power enters the control circuit 600 from the fast charging interface 300. The control module 610 allocates power supply according to the needs of each interface, and the power is output to the connected device through the terminal connector 100, the fast charging interface 300, or other interfaces. Audio / video signals and data signals enter the control circuit 600 from the terminal connector 100. The communication protocol module 630 identifies the communication protocol of the signal, and the signal conversion module 620 converts the signal into a format suitable for peripherals or displays to receive.
