The design of cable connector assembly 100 not only affects the shape of the head-mounted display device but also the signal transmission between the terminal device and the head-mounted display device. Therefore, to ensure a good user experience, it is necessary to design the cable connector assembly 100 appropriately.

[0024] Exemplary Structure

[0025] Figure 1 This illustration shows a structural schematic of a cable connector assembly 100 provided in some exemplary embodiments of the present disclosure. Figure 2This illustration shows a schematic diagram of the flexible circuit board and data cable connector in a cable connector assembly provided by some exemplary embodiments of the present disclosure. In this embodiment, the cable connector assembly 100 may include: a data cable connector 1, a coaxial cable 2, and a flexible circuit board 3. The data cable connector 1 can be used to connect to an external terminal device, such as a mobile phone, computer, etc. Optionally, the data cable connector 1 can be connected to an external terminal device via a data cable. Therefore, the data cable connector 1 can be connected to a data cable. One end of the coaxial cable 2 can be electrically connected to the data cable connector 1. The other end of the coaxial cable 2 can be provided with a first motherboard connector 23. Optionally, the cable connector assembly can be disposed in a head-mounted display device, the first motherboard connector 23 can be used to connect to the motherboard of the head-mounted display device, and the coaxial cable 2 can be used to quickly transmit multimedia signals sent by the terminal device, etc. One end of the flexible circuit board 3 can be electrically connected to the data cable connector 1, and the other end of the flexible circuit board 3 can be provided with a second motherboard connector 31. Optionally, the cable connector assembly can be disposed in a head-mounted display device, and the second motherboard connector 31 can be used to connect to the motherboard of the head-mounted display device. The flexible circuit board 3 can be used to transmit control signals of components such as speakers, microphones, and buttons. The combination of coaxial cable 2 and flexible circuit board 3 ensures both the integrity of various functions and the viewing experience of multimedia.

[0026] It is understandable that head-mounted display devices can transmit not only multimedia signals and control signals, but also sensor signals, etc., through cable connector assemblies to terminal devices; there are no specific limitations here.

[0027] Figure 3 This illustration shows a structural schematic of a coaxial cable in a cable connector assembly provided by some exemplary embodiments of this disclosure. Coaxial cables are commonly used telecommunications transmission lines and are widely used in communications, television, wireless communications, military, and computer fields. A coaxial cable typically consists of multiple parts, which, from the inside out, may include a center conductor, an insulator, an outer conductor, and a jacket 21. The center conductor can be the first layer of the coaxial cable structure, typically made of copper, aluminum, or a copper alloy, and is the basis for signal transmission. The insulator is the medium between the center conductor and the outer conductor, typically made of polyethylene, polyvinyl chloride, or other plastics. The function of the insulator is to isolate the center conductor and the outer conductor, preventing signal leakage and interference. The outer conductor is the metallic shielding layer surrounding the center conductor, typically made of aluminum foil or tin-plated copper. The function of the outer conductor is to prevent signal leakage and external interference. The design of the outer conductor is one of the important factors in cable performance. The jacket 21 is the outermost covering layer, typically made of PVC plastic, polyvinyl chloride, nylon, etc., and is used to protect the entire cable from mechanical damage and external environmental corrosion.

[0028] In some possible implementations, the coaxial cable 2 can be used to transmit multimedia signals, and the flexible circuit board 3 can be used to transmit control signals from any one or more of the speakers, microphones, and control components. The cable connector assembly 100 provided in this disclosure embodiment simultaneously incorporates the coaxial cable 2 and the flexible circuit board 3, ensuring both the integrity of various control functions and the transmission rate of multimedia signals, thereby enhancing the user experience.

[0029] In some possible implementations, such as Figure 1 As shown, the flexible circuit board 3 can extend along the length direction of the coaxial line 2, and the flexible circuit board 3 and the coaxial line 2 are fixedly connected along the thickness direction of the flexible circuit board 3.

[0030] The flexible circuit board 3 can be elongated and is connected to the outer wall of the coaxial line 2 along its thickness direction. The flexible circuit board 3 also extends along the length direction of the coaxial line 2, and the two are fixedly connected, reducing the thickness and preventing wobbling. This facilitates placement inside the temple 220 of the head-mounted display device 200. Optionally, the flexible circuit board 3 and the coaxial line 2 can be used to transmit different types of signals. This ensures that the two different signal transmission media, the flexible circuit board 3 and the coaxial line 2, are stacked and fixed along the thickness direction of the coaxial line, preventing signal interference and guaranteeing signal transmission quality.

[0031] In some possible implementations, such as Figure 1 and Figure 2 As shown, the data cable connector 1 may include a data cable connection part 11, which can be electrically connected to the flexible circuit board 3 for detachably connecting the flexible circuit board 3 and the external data cable. The data cable connection part 11 may include any one of a Type-C interface, a Micro USB interface, and a Lightning interface, facilitating detachable connection with the terminal device via an external data cable. When the data cable connector 1 is connected to the terminal device via an external data cable, the flexible circuit board 3 can be used to transmit signals other than video signals sent by the terminal device, such as audio signals and control signals, to the motherboard of the head-mounted display device 200.

[0032] In some possible implementation schemes, combined Figures 1 to 3As shown, the data cable connector 1 may include a coaxial cable connection portion 12. The coaxial cable connection portion 12 can be electrically connected to the flexible circuit board 3. One end of the coaxial cable 2 is provided with a connection terminal 24, and the coaxial cable 2 is detachably electrically connected to the coaxial cable connection portion 12 through the connection terminal 24. When the data cable connector 1 is connected to the terminal device via an external data cable, the coaxial cable 2 is used to transmit the video signals and electrical signals sent by the terminal device to the main board of the head-mounted display device 200, while the flexible circuit board 3 is used to transmit signals other than video signals sent by the terminal device, such as audio signals and control signals, to the main board of the head-mounted display device 200.

[0033] In some alternative embodiments, the coaxial cable 2 and the flexible circuit board 3 can be connected in different ways. The coaxial cable 2 and the flexible circuit board 3 can be bonded together, for example, by applying adhesive between the outer wall of the coaxial cable 2 and the flexible circuit board 3. Alternatively, the coaxial cable 2 and the flexible circuit board 3 can be bonded together using double-sided adhesive, i.e., the coaxial cable 2 and the flexible circuit board 3 are bonded to both sides along the thickness direction of the double-sided adhesive. The coaxial cable 2 and the flexible circuit board 3 can also be connected and fixed using a connector. The connector can be sleeved on the coaxial cable 2 and the flexible circuit board 3 to bind them together. For example, the connector can be a flexible sleeve, with multiple flexible sleeves sleeved on the flexible circuit board 3 and the coaxial cable 2, and the flexible sleeves arranged sequentially along the length direction of the flexible circuit board 3 to bind and fix them together.

[0034] In some possible implementation schemes, combined Figure 1 and Figure 2 As shown, the coaxial cable 2 may include an outer sleeve 21, and the central conductor of the coaxial cable 2 may include multiple wire bundles 22. Each wire bundle 22 may be arranged sequentially along the width direction of the flexible circuit board 3, and the outer sleeve 21 is fitted over the outside of the multiple wire bundles 22.

[0035] The central conductor of the coaxial cable 2 comprises multiple wire bundles 22, which are arranged sequentially along the width direction of the flexible circuit board 3. This forms a sheet-like structure, making the entire coaxial cable 2 flat and laid out on the flexible circuit board 3, which helps reduce the thickness of the cable connector assembly 100. When the cable connector assembly is installed in a head-mounted display device, it facilitates its placement inside the temple 220 of the head-mounted display device 200. When the cable connector assembly 100 is mounted on the temple 220 of the head-mounted display device 200, the thickness direction of the cable connector assembly 100 is parallel to the thickness direction of the temple 220.

[0036] Figure 4An exploded view of a coaxial cable in a cable connector assembly provided by some exemplary embodiments of the present disclosure is shown. The cable connector assembly 100 may include at least two outer sleeves 21, each sleeve 21 being respectively fitted onto the coaxial cable 2 and the flexible circuit board 3, with the outer sleeves 21 spaced apart along the length direction of the flexible circuit board 3. The outer sleeves 21 are partially wrapped around the coaxial cable 2 along its length direction, and the multiple outer sleeves 21 cooperate to bind the wire bundle 22, keeping the wire bundle 22 in a gathered state and preventing the wire bundles from becoming messy and scattered.

[0037] In some possible implementations, the outer surface of the outer jacket 21 is bonded to the flexible circuit board 3. The outer jacket 21 can be directly bonded to the flexible circuit board 3 using adhesive. Alternatively, the outer jacket 21 can be bonded to the flexible circuit board 3 using double-sided adhesive. For example, the double-sided adhesive can be used to bond the flexible circuit board 3 and the outer jacket 21 on both sides along the thickness direction. Using double-sided adhesive for bonding results in a simple overall structure and improves assembly efficiency.

[0038] In some possible implementations, the inner wall of the outer jacket 21 has an adhesive layer, and the inner wall of the outer jacket 21 is bonded and fixed to the wire harness 22. By applying an adhesive layer to the inner wall of the outer jacket 21, the individual wire harnesses 22 can be bonded and fixed, so that the positions of the individual wire harnesses 22 are fixed, and the individual wire harnesses 22 can be arranged sequentially along the width direction of the flexible circuit board 3, avoiding the wire harnesses 22 from shifting and forming a double-layer or multi-layer structure.

[0039] In some possible implementations, such as Figure 2 As shown, the flexible circuit board 3 has an external circuit board area 32 and an extended circuit board area 33. The extended circuit board area 33 can be located on both sides of the external circuit board area 32. The extended circuit board area 33 on one side of the external circuit board area 32 is electrically connected to the data cable connector 1, and the extended circuit board area 33 on the other side of the external circuit board area 32 is provided with a second motherboard connector 31. The external circuit board area 32 is used for soldering and fixing electronic components. The electronic components may include at least one of a speaker, a microphone, and a control device. The external circuit board area 32 of the flexible circuit board 3 can directly solder the speaker, microphone, and control device, avoiding the need for external cables to connect the various electronic components, thereby making the wiring of the temple 220 of the head-mounted display device 200 simpler. Optionally, the control device can be a button.

[0040] In some possible implementations, such as Figure 2 As shown, the width of the external circuit board area 32 can be greater than the width of the extension circuit board 33 and the outer diameter of the coaxial line 2. The external circuit board area 32 protrudes to both sides of the extension circuit board 33 in the width direction, increasing the width and facilitating the placement of speakers, microphones, and control components. The speakers, microphones, and control components can be directly soldered onto the flexible circuit board 3.

[0041] Figure 5This diagram illustrates a perspective view of a head-mounted display device provided with some exemplary embodiments of the present disclosure. The head-mounted display device 200 includes a frame 210, temples 220, a mainboard, and the aforementioned cable connector assembly 100. The temples 220 are connected to the frame 210, and the mainboard is disposed on either the frame 210 or the temples 220. The cable connector assembly 100 provided in the above embodiments can all be applied to the head-mounted display device 200 of this application. Optionally, the cable connector assembly 100 may be at least partially disposed on the temples 220, and the first mainboard connector 23 and the second mainboard connector 31 of the cable connector assembly 100 are electrically connected to the mainboard. The thickness direction of the flexible circuit board 3 in the cable connector assembly 100 is parallel to the thickness direction of the temples 220. The wire bundles 22 of the coaxial cable 2 in the cable connector assembly 100 are arranged sequentially along the width direction of the temples 220. The cable connector assembly 100 can be a flat strip, and its structural design is adapted to the thickness requirements of the temples 220. When the cable connector assembly 100 is assembled on the temple 220, the thickness direction of the cable connector assembly 100 is parallel to the thickness direction of the temple 220, so that the cable connector assembly 100 can be smoothly assembled inside the temple 220, the thickness of the temple 220 is controlled, and the comfort of the user wearing the head-mounted display device is improved.

[0042] In some possible implementations, such as Figure 5 As shown, the data cable connector 1 of the cable connector assembly 100 is disposed at one end of the temple 220 away from the frame 210. The data cable connector 1 is located at the tail end of the temple 220, and the connector interface is exposed on the temple 220 to facilitate connection with terminal devices.
