[0003] Embodiments of the present disclosure relate to the technical field of smart glasses, and particularly to a terminal assembly and a data cable for split-type smart glasses. Background Art

[0004] Smart glasses include integrated and split-type smart glasses. Split-type smart glasses include a terminal device and a smart glasses body. The terminal device is connected to the smart glasses body via a Universal Serial Bus (USB) module. For some displays that include a High Definition Multimedia Interface (HDMI), the terminal device connects to the display via an HDMI module.

[0005] However, when using the above terminal devices, the following technical problems often occur:

[0006] Since communication between the terminal device and the smart glasses body cannot be achieved when the terminal device and the smart glasses body are connected through an HDMI to Type C converter, the terminal device needs to set up two interfaces (i.e., HDMI and USB interfaces) in order to achieve both communication with the smart glasses body and connection with the above-mentioned display. There are many interfaces set on the terminal device, and the probability of pollutants such as dust and sweat entering the terminal device is relatively high, thereby causing a high probability of damage to the terminal device.

Therefore, in order to achieve both communication with the smart glasses body and connection with the display, the terminal device needs to be provided with two interfaces (i.e., HDMI and USB interfaces). There are many interfaces provided on the terminal device, and the probability of pollutants such as dust and sweat entering the terminal device is high, resulting in a high probability of damage to the terminal device. Based on this, some embodiments of the present disclosure include a terminal assembly for split-type smart glasses, including a terminal body, a signal converter, and at least one data line. The terminal body includes a main control module, a switching module, a multimedia module, a communication module, and a terminal multimedia interface, wherein the main control module and the terminal multimedia interface are both connected to the switching module; the signal converter includes a converter chip, a converter multimedia interface, and a converter communication interface, wherein the converter multimedia interface and the converter communication interface are communicatively connected; one end of each of the at least one data line is connected to the signal converter; when the terminal body is connected to a multimedia device, the switching module is connected to the multimedia module; when the converter communication interface is connected to the smart glasses, the terminal multimedia interface is connected to the converter multimedia interface, and the switching module is connected to the communication module. Because the switching module is connected to the multimedia module when the terminal body is connected to the multimedia device, audio and video transmission between the multimedia module included in the terminal body and a display screen including HDMI can be achieved. Also, because the switching module is connected to the communication module when the converter communication interface is connected to the smart glasses, communication between the terminal body and the smart glasses can be achieved through the converter. Therefore, the terminal component for split smart glasses can enable the smart glasses to still communicate with the terminal via USB when connected to the terminal through an HDMI converter, thereby reducing the number of interfaces on the terminal and reducing the probability of damage to the terminal device.

For example, the metal shielding layer may be aluminum foil. Specifically, the outer ring of the first and second electronic wire groups 332 may be wrapped with the metal shielding layer. The outer ring of the second and second electronic wire groups 333 may also be wrapped with the metal shielding layer.

[0067] Optionally, the first electronic wire group 332 may further include a ground wire and a bulletproof wire. The ground wire may be used to connect to the ground, the outer casing, or a conductor with a reference potential of zero. The bulletproof wire may be a wire made of high-density fiber. The ground wire and the bulletproof wire may be twisted together with the first power line, the second power line, and the two first data lines to obtain the first electronic wire group 332. The wire core layer 33 may include at least one bulletproof wire. Specifically, the wire core layer 33 may include three bulletproof wires. The at least one bulletproof wire may be twisted together with each coaxial line, the first electronic wire group 332, and the second electronic wire group 333 to form the wire core layer 33. Thus, by providing the bulletproof wire and the ground wire, the pull resistance of the data line can be improved.

[0068] By selecting a thinner core than conventional wires, the data cable can be made smaller in diameter and lighter in weight while meeting the required audio and video transmission bandwidth. Furthermore, a shielding layer is wrapped around the outside of both the first and second electronic wire groups, thereby improving the data cable's anti-interference capabilities.
