Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber production, in particular to an HDMI2.0 optical fiber connecting cable. Background Technique

[0002] High-Definition Multimedia Interface (HDMI) is a digital video / audio interface technology, a dedicated digital interface suitable for video transmission, which can transmit audio and video signals simultaneously. At present, it has been widely used in electronic products such as set-top boxes, DVD players, personal computers, video game consoles, integrated amplifiers, digital audio and televisions;

[0003] During the use of the existing HDMI2.0 optical fiber connecting cable, there are at least the following disadvantages: the existing connector does not have the performance of dust prevention. After the connector is connected to the device, the connection part between the connector and the device is generally exposed. Although it will not directly affect the signal transmission of the optical fiber at the beginning, however, after long-term use, more dust is likely to accumulate at the connection, and the dust is likely to affect the device interface, thus leading to line failures. Moreover, the existing connecting cable does not have strong heat insulation performance in terms of structure. When the ambient temperature is high, affected by the temperature, it is easy to reduce the signal transmission rate of the optical fiber and is easily interfered by the surrounding electromagnetic environment, resulting in unstable signal transmission. Therefore, we introduce a new HDMI2.0 optical fiber connecting cable. Content of the Utility Model

[0012] Preferably, the structure of the upper magnetic dust-proof shell is the same as that of the lower magnetic dust-proof shell and they are symmetrically distributed up and down.

[0013] By adopting the above technical solution: Ensure the stable magnetic installation of the lower end of the upper magnetic dust-proof shell and the upper end of the lower magnetic dust-proof shell. The same and symmetrically distributed structures are convenient for production and manufacturing, and reduce costs.

[0014] Preferably, several of the clamping grooves are all in an arc structure.

[0015] By adopting the above technical solution: The arc-shaped clamping grooves can better fit the shape of the fixed head, provide a more compact wrapping and protection, and enhance the dust-proof effect.

[0016] Preferably, the two protection bodies are both located inside the fixed head.

[0017] By adopting the above technical solution: The protection bodies can provide more direct and effective protection for the connecting cable body and the docking cable body inside the fixed head, and prevent external factors from damaging the cable connection part.

[0030] An HDMI 2.0 fiber optic cable, comprising a connecting cable body 1 and a docking cable body 3. Connecting devices 2 are fixedly connected to the outer surfaces of both the connecting cable body 1 and the docking cable body 3. A fixing head 5 is fixedly connected to the outer sides of the two connecting devices 2, and a dust-proof device 4 is installed on the outer side of the fixing head 5.

[0031] In this embodiment, the connecting device 2 includes a protection body 21. A wear-resistant layer 22 is fixedly connected to the outer side of the protection body 21, a heat dissipation layer 23 is fixedly connected to the inner wall of the protection body 21, a heat insulation layer 24 is fixedly connected inside the heat dissipation layer 23, and the protection body 21 is fixedly connected to the outer sides of the docking cable body 3 and the connecting cable body 1 respectively; the two protection bodies 21 are jointly located inside the fixing head 5.

[0032] Through the above solution: The protective body 21 serves as the basic structure and is directly connected to the docking cable body 3 and the connecting cable body 1, providing the main physical protection for the internal cables. The outer wear-resistant layer 22 bears the wear when the connecting cable contacts and rubs against external objects, protecting the internal structure from damage, thereby extending the service life of the connecting cable. The heat dissipation layer 23 on the inner wall of the protective body 21 can absorb and conduct the heat generated during the operation of the cable, quickly dissipate the heat, and prevent the cable from being damaged due to overheating or affecting the signal transmission quality. The heat insulation layer 24 in the heat dissipation layer 23 blocks the influence of external high temperature on the inside of the cable, ensuring that the cable works in a suitable temperature environment and maintaining stable signal transmission performance. The two protective bodies 21 are both located inside the fixing head 5, further enhancing the protection of the cable connection part and reducing the interference of external factors on the connection stability and signal transmission.

[0033] In this embodiment, the dust-proof device 4 includes an upper magnetic dust-proof shell 41 and a lower magnetic dust-proof shell 45. Clamping grooves 42 are formed at the lower end of the upper magnetic dust-proof shell 41 and the upper end of the lower magnetic dust-proof shell 45. Rubber pads 43 are fixedly connected in the clamping grooves 42.

The upper magnetic dust-proof shell 41 and the lower magnetic dust-proof shell 45 are both located outside the fixing head 5; the lower end of the upper magnetic dust-proof shell 41 and the upper end of the lower magnetic dust-proof shell 45 are magnetically installed; the structure of the upper magnetic dust-proof shell 41 is the same as that of the lower magnetic dust-proof shell 45 and they are symmetrically distributed up and down; several clamping grooves 42 are all in an arc structure.

[0034] Through the above solution: The upper magnetic dust-proof shell 41 and the lower magnetic dust-proof shell 45 are quickly and tightly connected through magnetic attraction. The design of the clamping grooves 42 enables the dust-proof shell to closely fit the fixing head 5.

During use, the connection cable body 1 and the docking cable body 3 are used to transmit HDMI 2.0 signals. The protective body 21 in the connection device 2 provides basic protection for the internal cables. The outer wear-resistant layer 22 can reduce the damage caused by friction during the use of the connection cable, extending the service life. The heat dissipation layer 23 on the inner wall helps to dissipate the heat generated when the cable is working, preventing overheating from affecting the performance. The heat insulation layer 24 reduces the influence of external heat on the inside of the cable, ensuring the stability of signal transmission. The fixing head 5 is used to firmly connect the connection cable body 1 and the docking cable body 3. The upper magnetic dust-proof shell 41 and the lower magnetic dust-proof shell 45 in the dust-proof device 4 are installed by magnetic attraction. The rubber pad 43 in the clamping groove 42 can closely fit the fixing head 5. The arc-shaped clamping groove 42 can better adapt to the shape of the fixing head 5, playing a dust-proof role.
