Abstract
Description
Technical Field
[0001] This utility model relates to the field of fiber optic cable technology, and more specifically, to a tensile-resistant HDMI fiber optic cable. Background Technology
[0002] HDMI fiber optic cables are small and lightweight, making them widely used. They can transmit both video and audio, meaning connecting an HDMI fiber optic cable is equivalent to using both video and audio transmission simultaneously. HDMI cables are audio and video transmission cables, a characteristic of the HDMI interface. From version 1.0 to the current version 2.1, the HDMI interface itself appeared in 2002. Early versions of the HDMI interface did not support wide color gamut and high-resolution products. Currently, the widely used HDMI professional cables are HDMI 2.0 high-definition cables. Compared to earlier versions, HDMI 2.0 not only offers several times the transmission speed but also improves color reproduction and significantly enhances audio transmission performance, supporting 32 lossless audio streams for home theater-level sound effects. Therefore, HDMI 2.0 can easily achieve home theater-level sound.
[0003] Existing HDMI fiber optic cables have two main problems in use: First, they have poor tensile strength, relying on a single structure to withstand tension, making them prone to breakage during daily pulling, installation, and relocation, thus affecting their lifespan; second, when used with other cables, they lack convenient bundling structures, leading to messy accumulation, tangling, and pulling, increasing management difficulty and reducing ease of use. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides a tensile-resistant HDMI fiber optic cable that is resistant to tension and easy to bundle with other cables, thereby solving the problems mentioned in the background technology.
[0006] (II) Technical Solution
[0007] To achieve the aforementioned advantages of tensile strength and ease of bundling with other cables, the specific technical solution adopted by this utility model is as follows: A tensile HDMI fiber optic cable includes a cable body. Several fiber optic cores are arranged parallel to each other inside the cable body. A water-blocking sheath layer is extruded onto the outside of each fiber optic core. The gap between the fiber optic cores and the water-blocking sheath layer is filled with non-woven PP rope-type filler material. A tensile layer is wound around the outside of the water-blocking sheath layer, and an insulating outer sheath is extruded onto the outside of the tensile layer. Multiple tensile ropes are embedded inside the insulating outer sheath along the length of the cable body. Both the tensile ropes and the tensile layer are made of aramid fiber rope. Several annular clamps are evenly spaced on the surface of the cable body. Each annular clamp has a pre-drilled notch at its bottom, and a first adhesive tape and a second adhesive tape are fixed to the left and right sides of each annular clamp.
[0008] Furthermore, the surface of the first adhesive tape is sewn with a hook and loop fastener, and the surface of the second adhesive tape is sewn with a hook and loop fastener corresponding to the hook and loop fastener. The outer surface of the annular wire hoop has two concave openings at an angle. The opposing ends of the first and second adhesive tapes extend to the inside of the two concave openings, and the connection between the first and second adhesive tapes and the two concave openings is filled with sealant.
[0009] Furthermore, the lengths of the multiple tensile ropes are adapted to the length of the connecting line body, and the multiple tensile ropes are arranged around the axis of the connecting line body.
[0010] Furthermore, the inclination angle of the aramid fiber rope winding in the tensile layer ranges from 15° to 30°.
[0011] Furthermore, the inner diameter of the annular clamp matches the diameter of the connecting wire body, and the width of the loading and unloading notch of the annular clamp is smaller than the diameter of the connecting wire body.
[0012] Furthermore, both ends of the connecting cable body are equipped with HDMI connectors, and the surface of the HDMI connectors is provided with a mesh anti-slip texture.
[0013] (III) Beneficial Effects
[0014] Compared with the prior art, this utility model provides a tensile-resistant HDMI fiber optic cable, which has the following advantages:
[0015] This invention incorporates a tensile-resistant layer and multiple tensile-resistant ropes. The tensile-resistant layer and ropes employ a combination of winding and axial arrangement for tensile resistance. The aramid fiber ropes of the tensile-resistant layer are wound around the outside of the water-blocking sheath at an angle of 15°-30°, a winding method that disperses tensile forces in different directions. Simultaneously, multiple tensile-resistant ropes embedded within the insulating outer sheath along the length of the connecting wire are arranged around the axis, capable of withstanding the main axial tensile force. The combined effect of these two elements significantly enhances the overall tensile strength of the connecting wire, effectively preventing breakage due to pulling during daily use, installation, or relocation, and significantly extending its service life.
[0016] This utility model features annular cable hoops evenly spaced on the surface of the connecting cable body. On its left and right sides are respectively fixed a first adhesive tape 4 with a hook side and a rough side with hook and loop fasteners, and a second adhesive tape 5. Through the quick application and detachment of the hook and loop fasteners, this HDMI fiber optic cable can be easily bundled with other cables, reducing cable clutter and saving space. It also prevents cables from tangling and pulling, facilitating management and maintenance, and improving ease of use and functionality. Attached Figure Description

[0024] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments.

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.
[0025] According to an embodiment of the present invention, a tensile-resistant HDMI fiber optic cable is provided.
[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, a tensile-resistant HDMI fiber optic cable according to an embodiment of the present invention includes a cable body 1. A plurality of fiber optic cores 8 are arranged parallel to each other inside the cable body 1. A water-blocking sheath layer 9 is extruded onto the outside of the plurality of fiber optic cores 8. The gap between the plurality of fiber optic cores 8 and the water-blocking sheath layer 9 is filled with non-woven PP rope-type filler material. A tensile-resistant layer 10 is wound around the outside of the water-blocking sheath layer 9. An insulating outer sheath layer 11 is extruded onto the outside of the tensile-resistant layer 10. Multiple tensile-resistant ropes 12 are embedded and installed inside the insulating outer sheath layer 11 along the length direction of the cable body 1. Both the tensile rope 12 and the tensile layer 10 are made of aramid fiber rope. Several annular clamps 3 are evenly spaced and installed on the surface of the connecting cable body 1. Each annular clamp 3 has a pre-drilled opening 13 at its bottom. A first adhesive tape 4 and a second adhesive tape 5 are fixed to the left and right sides of each annular clamp 3. To improve the performance of the connecting cable, a water-blocking sheath layer 9 is extruded onto the outside of several optical fiber cores 8. This sheath layer is made of a highly sealing material, effectively preventing external moisture intrusion and avoiding the transmission quality being affected by moisture in the optical fiber cores 8, thus significantly extending the service life of the connecting cable. Simultaneously, non-woven PP rope-type filler material is used to fill the gaps between the several optical fiber cores 8 and the water-blocking sheath layer 9. This material not only has a good cushioning effect, reducing the impact of external impacts on the optical fiber cores 8, but also makes the internal structure more compact, preventing displacement of the optical fiber cores 8 during use. A tensile layer 10 is wound around the water-blocking sheath layer 9, and an insulating outer sheath 11 is extruded over the tensile layer 10. The insulating outer sheath 11 is made of high-quality insulating material, which can effectively isolate external current and electromagnetic interference, ensuring safe use and the purity of signal transmission. It is worth noting that multiple tensile ropes 12 are embedded inside the insulating outer sheath 11 along the length of the connecting wire body 1, and both the multiple tensile ropes 12 and the tensile layer 10 are made of aramid fiber rope. Aramid fiber rope has extremely high strength and tensile properties, which can significantly improve the tensile strength of the entire connecting wire, making it less prone to breakage when subjected to large tensile forces. In addition, several annular clamps 3 are evenly spaced on the surface of the connecting wire body 1. These annular clamps 3 can fix and protect the connecting wire to a certain extent. Each annular clamp 3 has a loading and unloading notch 13 at the bottom to facilitate the installation and removal of the clamp. Furthermore, each annular clamp 3 has a first adhesive tape 4 and a second adhesive tape 5 fixed on its left and right sides to facilitate fixing the connecting wire to other objects and reduce its shaking during use.
[0027] Please refer to Figure 2 and Figure 4The surface of the first adhesive tape 4 is sewn with a hook and loop fastener 6, and the surface of the second adhesive tape 5 is sewn with a hook and loop fastener 7 corresponding to the hook and loop fastener 6. The outer surface of the annular wire clamp 3 has two concave insertion slots at an angle. The opposing ends of the first adhesive tape 4 and the second adhesive tape 5 extend to the inside of the two concave insertion slots respectively, and the connection between the first adhesive tape 4 and the second adhesive tape 5 and the two concave insertion slots is filled with sealant. This hook and loop fastener design allows the first adhesive tape 4 and the second adhesive tape 5 to be quickly attached and detached, which is convenient to operate and firmly attached, and can stably fix the connecting wire in the required position. The outer surface of the annular wire clamp 3 has two concave sockets at an angle. The angled design allows the adhesive tape to fit more closely when connected, avoiding wrinkles that could affect the fixing effect. The opposing ends of the first adhesive tape 4 and the second adhesive tape 5 extend into the inner side of the two concave sockets, and the connection between the first adhesive tape 4 and the second adhesive tape 5 and the two concave sockets is filled with sealant. The sealant can enhance the sealing and firmness of the connection, prevent moisture from seeping into the interior of the annular wire clamp 3 from the interface, and also prevent the adhesive tape from falling off from the socket during long-term use.
[0028] Please refer to Figure 2 The lengths of the multiple tensile ropes 12 are adapted to the length of the connecting wire body 1, and the multiple tensile ropes 12 are arranged around the axis of the connecting wire body 1. This structure allows the tensile ropes 12 to extend from one end of the connecting wire to the other, fully exerting their tensile resistance and ensuring that the connecting wire has good tensile performance throughout its entire length. Furthermore, the arrangement of the multiple tensile ropes 12 around the axis of the connecting wire body 1 ensures that the tensile force is evenly distributed in all directions of the connecting wire, preventing damage due to excessive localized stress, and further improving the overall tensile strength and service life of the connecting wire.
[0029] Please refer to Figure 3 The aramid fiber rope of the tensile layer 10 is wound at an angle ranging from 15° to 30°. This angle range ensures that the tensile layer 10 maintains good tensile strength without excessively increasing the stiffness of the connecting wire, allowing it to retain a certain degree of flexibility for easy bending and storage. If the angle is too small, the tensile effect of the tensile layer 10 will be weakened; if the angle is too large, the connecting wire will become too stiff and less flexible in use. Therefore, 15°-30° is the optimal angle range that balances tensile strength and flexibility.
[0030] Please refer to Figure 1-3The inner diameter of the annular clamp 3 matches the diameter of the connecting wire body 1, and the width of the loading / unloading notch 13 of the annular clamp 3 is smaller than the diameter of the connecting wire body 1. This design allows the annular clamp 3 to fit tightly onto the connecting wire body 1, preventing loosening and ensuring the clamp's fixation and protection of the connecting wire. Furthermore, the smaller width of the loading / unloading notch 13 means that during installation, a slight force is needed to open the notch before it can be fitted onto the connecting wire. After installation, the clamp's elasticity will tightly wrap around the connecting wire, preventing it from falling off during use and ensuring it always performs its intended function.
[0031] Please refer to Figure 1 Both ends of the connector cable body 1 are equipped with HDMI connectors 2, and the surface of the HDMI connectors 2 is decorated with a mesh-like anti-slip texture. The HDMI connectors 2 adopt a standardized design, which can perfectly adapt to various devices with HDMI interfaces, and realize high-definition transmission of audio and video signals. The mesh-like anti-slip texture on the surface of the HDMI connectors 2 increases the friction between the hand and the connector, providing a better grip when plugging and unplugging the connector, avoiding slippage, and making plugging and unplugging operations easier and more convenient.
[0032] Working principle: When transmitting signals, the several optical fiber cores 8 inside the connector body 1 are the core of signal transmission. The parallel arrangement reduces signal interference and ensures stable transmission of audio and video signals. The water-blocking sheath layer 9 is wrapped around the outside of the optical fiber core 8 through extrusion molding, blocking external moisture from entering and protecting the optical fiber core 8 from moisture. The non-woven PP rope-type filling material between it and the optical fiber core 8 makes the internal structure more compact, buffers external impacts, and prevents the optical fiber core 8 from shifting. When tensile, the aramid fiber rope of the tensile layer 10 is wound around the outside of the water-blocking sheath layer 9 at an angle of 15°-30°. When the connecting line is subjected to tensile force in different directions, the wound fiber rope can disperse the tensile force. Multiple aramid fiber tensile ropes 12 embedded in the inner insulation outer sheath 11 along the length direction are arranged around the axis and mainly bear the axial tensile force. The combination of the two forms an all-round tensile protection to ensure that the connecting line is not easily damaged when under force. When it is necessary to bind with other lines, the ring clamp 3 is put on the connecting line body 1 through the loading and unloading notch 13 at the bottom. Because the width of the loading and unloading notch 13 is smaller than the diameter of the connecting line, the ring clamp 3 can tightly wrap the connecting line and is not easy to fall off. The first adhesive tape 4 and the second adhesive tape 5 on both sides can be quickly attached using the hook and loop sides 6 and 7 of the surface, achieving bundling and fixing with other cables, reducing cable movement and tangling. In addition, the HDMI connectors 2 at both ends of the cable adopt a standardized design, and the mesh anti-slip texture on the surface facilitates plugging and unplugging, achieving a stable connection with the device and completing the signal transmission path.
