[0002] In modern electronic devices, the HDMI (High Definition Multimedia Interface) connector plays a crucial role, enabling the transmission of uncompressed high-definition video and multi-channel audio data. Traditional HDMI connectors use copper wires as the signal transmission medium, but this has some limitations. With the development of display technology and the increasing demand for high-definition video and audio transmission, traditional copper-wire HDMI connectors are gradually becoming unable to meet market needs.

[0003] Limitations of traditional HDMI connectors: First, high manufacturing cost. Traditional HDMI connectors use copper wires as the signal transmission medium, and copper is a relatively expensive material, resulting in high manufacturing costs. Second, heavy weight. The weight of the copper wires increases the overall weight of the HDMI cable, making it less portable and easier to transport. Third...

[0004] Significant signal attenuation occurs in copper HDMI cables during long-distance transmission, affecting the quality and stability of audio and video signals. This makes them unsuitable for long-distance high-definition audio and video signal transmission, limiting their application scope.

[0005] In view of the above problems, developing a new type of HDMI connector to overcome the limitations of traditional copper wire HDMI connectors has become an urgent need for industry development. Utility Model Content

[0019] Furthermore, the HDMI fiber optic cable in this application also has the following advantages:

[0020] First, using optical fiber as the transmission medium significantly increases the signal transmission distance. Optical fiber is unaffected by electromagnetic interference, maintaining signal integrity and stability over distances of hundreds of meters, without the signal attenuation problems commonly found in traditional copper HDMI connectors over long distances. This characteristic makes HDMI fiber optic cables an ideal choice for long-distance transmission scenarios such as home theaters, large conference rooms, and surveillance systems.

[0021] Secondly, HDMI fiber optic cables have extremely strong anti-interference capabilities. Because fiber optics transmit optical signals, not electrical signals, they are not subject to electromagnetic interference, ensuring signal purity. This is especially important in complex electronic environments, such as those with dense equipment or strong electromagnetic fields, where HDMI fiber optic connectors can provide a stable and reliable connection.

[0022] Third, HDMI fiber optic cables are lightweight and compact, making them easy to transport and install. The slender nature of optical fibers makes HDMI fiber optic connectors more flexible and adaptable, facilitating cabling in narrow or curved spaces while also reducing the weight burden of long-distance cabling.

[0023] Fourth, HDMI fiber optic cables support higher transmission rates. With the development of high-definition video technology, the demand for transmission bandwidth is increasing. HDMI fiber optic connectors can support transmission rates up to 48Gbps, meeting the needs of future high-definition video transmission such as 8K video, while traditional copper wire HDMI connectors are already approaching their physical limits in terms of transmission rate.

[0024] Fifth, HDMI fiber optic cables also have advantages in terms of energy saving and environmental protection. Since fiber optic transmission does not require an additional power source, it does not generate additional energy consumption during the entire transmission process, which helps to reduce overall energy consumption.

Detailed Implementation

[0045] As shown in Figures 1 to 17, this utility model discloses an HDMI fiber optic cable with a quick-assembly and disassembly module, comprising a housing 10, a fiber optic input connector 20 installed in the housing 10, and a conversion module 30, wherein:

[0046] The conversion module 30 is detachably installed in the housing 10 and plugs into the fiber optic input connector 20. The conversion module 30 has a flexible limiting arm 31, a terminal socket 32, and an optical module 33. The fiber optic input connector 20 includes a plug-in terminal 21 and a fiber optic input interface 22. The plug-in terminal 21 and the terminal socket 32 ​​are detachably coupled, and the fiber optic input interface 22 and the optical module 33 are detachably coupled. The front end of the flexible limiting arm 31 detachably abuts against the housing 10, locking / unlocking the conversion module 30 within the housing 10. A button 11 is provided on the housing 10 corresponding to the flexible limiting arm 31. Pressing the button 11 releases the front end of the flexible limiting arm 31 from the housing 10, thus unlocking the conversion module 30 from the housing 10. The housing 10 is made of aluminum alloy or zinc alloy; the specific material can be selected as needed.

[0047] At the four corners of the inlet of the outer casing 10, anti-misplacement rounded corners 18 are respectively provided to prevent the conversion module 30 from being inserted in reverse. The radii of the two anti-misplacement rounded corners 18 on the upper side are different from those on the lower side, while the radii of the two anti-misplacement rounded corners 18 on the same side (upper or lower) are the same, as shown in Figure 17. The outer wall of the conversion module 30 is provided with a matching anti-misplacement arc 30a corresponding to the anti-misplacement rounded corners 18 on the outer casing 10. When the conversion module 30 is inserted into the outer casing 10, due to the different radii of the upper and lower anti-misplacement rounded corners, it can only be inserted in the correct direction to enter the outer casing 10 and form a mating fit with the fiber optic input connector; otherwise, it cannot be inserted. This effectively avoids damage caused by reverse insertion, improving the product's anti-misplacement performance and ease of use.

[0048] The button 11 includes a fixed end 111 and an elastic end 112. The fixed end 111 includes an embedded fixing plate 1111 and a fixing post 1112.

Locking area 15; The embedded fixing plate 1111 is located in the fixing area 14, and the fixing post 1112 is embedded in the fixing hole 131. The rear end of the button 11 is fixed in the fixing area 14 by the cooperation between the embedded fixing plate 1111 and the fixing area 14 (the rear end of the embedded fixing plate 1111 is held by the rear edge of the fixing area 14) and the cooperation between the fixing post 1112 and the fixing hole 131; The elastic end 112 is located in the unlocking area 15; The front end of the elastic limiting arm 31 has a limiting block 311 adapted to the wedge block 1122. The limiting block 311 abuts against the inner edge of the unlocking area 15, so that the conversion module 30 cannot be removed from the outer shell 10, thereby forming a lock on the conversion module 30. Pressing down on the pressing part 1123 causes the wedge block 1122 to press down against the limiting block 311 of the elastic limiting arm 31, causing the front end of the elastic limiting arm 31 to disengage downward from the inner edge of the unlocking area 15. The conversion module 30 is then unlocked, and the conversion module 30 can be removed from the fiber optic input connector 20 and taken out of the housing 10 for replacement. In this embodiment, acrylic strip decorative panels 17 are respectively provided on both sides of the housing 10. One strip decorative panel 17 covers the strip through hole 12 on the housing 10.

[0055] The working principle of an HDMI fiber optic cable is to convert the HDMI electrical signal into an optical signal at the transmitting end, then transmit it through optical fiber to the receiving end, where the optical signal is converted back into an electrical signal, thereby achieving high-speed, long-distance, lossless transmission of audio and video signals. The HDMI fiber optic cable in this application also uses the same principle, and will not be elaborated upon here.

[0056] HDMI fiber optic cables offer the following advantages:

[0057] Long-distance transmission: HDMI fiber optic cables can achieve transmission distances of hundreds of meters or even longer, far exceeding the limitations of traditional copper HDMI cables.

[0058] High bandwidth: HDMI fiber optic cables can support higher bandwidth, easily meeting the transmission needs of high-resolution videos such as 4K and 8K.

[0059] Strong anti-interference capability: Due to the use of optical fiber transmission, the signal is not affected by electromagnetic interference, ensuring the stability and quality of transmission.

[0060] Energy-saving and environmentally friendly: Fiber optic transmission does not require current drive, has low energy consumption, and does not involve the use of harmful substances in the manufacturing process.

[0061] HDMI fiber optic cables can be widely used in applications requiring long-distance, high-bandwidth transmission, such as home theater systems, commercial displays, conference systems, and medical image transmission.

[0062] The HDMI fiber optic cable conversion module 30 can be replaced as needed. In specific operation, first press down on the pressing part 1123 of the button 11, so that the wedge block 1122 of the button 11 drives the limiting block 311 of the elastic limiting arm 31 downward, thereby causing the limiting block 311 to disengage from the inner edge of the unlocking area 15 of the housing 10, and the conversion module 30 is unlocked. At this time, pulling outward can remove the conversion module 30 from the fiber optic input connector 20 and detach it from the housing 10. Then, the new conversion module 30 can be inserted into the housing 10. At the same time, the pressing part 1123 of the button 11 is pressed to push the new conversion module 30 inward, so that it aligns with the fiber optic input connector 20. Then, the pressing part 1123 is released, and the limiting block 311 of the elastic limiting arm 31 of the new conversion module 30 springs back upward under its own elastic force and abuts against the inner edge of the unlocking area 15 of the housing 10, thereby locking and fixing the new conversion module 30 in the housing 10, thus completing the assembly.

[0063] The key design feature of this invention is that by using a pluggable conversion module that mates with the fiber optic input connector, and by providing a manually operable button between the housing and the conversion module to lock or unlock the module, quick and easy replacement of the conversion module is achieved. This allows the conversion module of the HDMI fiber optic cable to be replaced after a certain period of use, thus extending the lifespan of the HDMI fiber optic cable; furthermore, the quick and convenient replacement operation greatly facilitates product manufacturing and assembly.

[0064] Furthermore, the HDMI fiber optic cable in this application also has the following advantages:

[0065] First, using optical fiber as the transmission medium significantly increases the signal transmission distance. Optical fiber is unaffected by electromagnetic interference, maintaining signal integrity and stability over distances of hundreds of meters, without the signal attenuation problems commonly found in traditional copper HDMI connectors over long distances. This characteristic makes HDMI fiber optic cables an ideal choice for long-distance transmission scenarios such as home theaters, large conference rooms, and surveillance systems.

[0066] Secondly, HDMI fiber optic cables have extremely strong anti-interference capabilities. Because fiber optics transmit optical signals, not electrical signals, they are not subject to electromagnetic interference, ensuring signal purity. This is especially important in complex electronic environments, such as those with dense equipment or strong electromagnetic fields, where HDMI fiber optic connectors can provide a stable and reliable connection.

[0067] Third, HDMI fiber optic cables are lightweight and compact, making them easy to transport and install. The slender nature of optical fibers makes HDMI fiber optic connectors more flexible and adaptable, facilitating cabling in narrow or curved spaces while also reducing the weight burden of long-distance cabling.

[0068] Fourth, HDMI fiber optic cables support higher transmission rates. With the development of high-definition video technology, the demand for transmission bandwidth is increasing. HDMI fiber optic connectors can support transmission rates up to 48Gbps, meeting the needs of future high-definition video transmission such as 8K video, while traditional copper wire HDMI connectors are already approaching their physical limits in terms of transmission rate.

[0069] Fifth, HDMI fiber optic cables also have advantages in terms of energy saving and environmental protection. Since fiber optic transmission does not require an additional power source, it does not generate additional energy consumption during the entire transmission process, which helps to reduce overall energy consumption.

[0070] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
