Because when the terminal body is connected to a multimedia device, the switching switch module is connected to the multimedia module, so that the audio and video transmission between the multimedia module included in the terminal body and the display screen including HDMI can be realized. Also, because when the converter communication interface is connected to smart glasses, the switching switch module is connected to the communication module, and then the communication between the terminal body and the smart glasses can be realized through the converter. Therefore, the terminal component for split-type smart glasses can enable the smart glasses to still communicate with the terminal via USB when connected to the terminal via an HDMI converter, thereby reducing the number of interfaces on the terminal to reduce the probability of damage to the terminal device.

The outer ring of the second electronic wire group 333 may also be wrapped with a metal shielding layer.

[0064] 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 earth, the housing 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 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, the tear resistance of the data line may be improved by providing the bulletproof wire and the ground wire.

[0065] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: the data cables of some embodiments of the present disclosure can improve the convenience of use for users on the basis of meeting the bandwidth of audio and video transmission. Specifically, the reason why conventional data cables are less convenient for users to use is that for wearable devices that need to transmit data and power through data cables, the wire material of the above-mentioned data cables is relatively thick, resulting in a heavier weight. Based on this, the data cables of some embodiments of the present disclosure include an outer sheath, a winding layer and a wire core layer, wherein the above-mentioned winding layer is wound around the outer circle of the above-mentioned wire core layer, and the above-mentioned outer sheath is wrapped around the outer circle of the above-mentioned winding layer; the above-mentioned wire core layer includes various coaxial lines and electronic wire assemblies, and the diameter of each coaxial line is 0.39±0.05mm; the above-mentioned electronic wire assembly includes a first electronic wire group and a second electronic wire group; the above-mentioned first electronic wire group is composed of a first power line, a second power line and two first data lines twisted together, wherein the above-mentioned first power line and the above-mentioned second power line are obtained by twisting various metal wires, The first power line and the second power line both include an insulating layer for wrapping each metal wire, the core diameter of the first power line is 0.32±0.05mm, the core diameter of the second power line is 0.50±0.05mm, and the core diameter of each of the two first data lines is 0.30±0.05mm; the second electronic wire group is formed by twisting three second data wires; the first electronic wire group serves as the central part of the data line, and the coaxial lines and the second electronic wire group form a wrapping part around the first electronic wire group. Therefore, the data line of some embodiments of the present disclosure adopts a coaxial line, and by selecting a thinner core than a conventional core, the diameter of the data line can be smaller and the weight can be lighter on the basis of meeting the bandwidth of audio and video transmission. The first electronic wire group and the second electronic wire group are both wrapped with a shielding layer on the outside, so as to improve the anti-interference performance of the data line.

[0066] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of disclosure involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned disclosure concept. For example, the above-mentioned features are replaced with the technical features with similar functions disclosed in the embodiments of the present disclosure (but not limited to) to form a technical solution.
