Description

Technical Field

[0001] This utility model relates to the field of HDMI transmission line technology, specifically to an HDMI anti-interference transmission line based on multi-layer shielding. Background Technology

[0002] HDMI cables, or High Definition Multimedia Interface cables, are fully digital interface cables used in both consumer electronics and PCs to transmit uncompressed audio and video signals. Using HDMI cables significantly simplifies the number of interface cables; a single cable can replace up to 13 analog cables, effectively solving the problem of messy and tangled wiring behind home entertainment systems.

[0003] Currently, HDMI cables lack multi-layer shielding structures. During use, electromagnetic interference from external devices such as Wi-Fi, mobile phones, and power supplies can easily affect data transmission stability. Therefore, this paper proposes a multi-layer shielded HDMI anti-interference cable to enhance its anti-interference performance, improve operational stability, and ultimately enhance user experience. Utility Model Content

[0005] The technical solution adopted by this utility model to solve its technical problem is an HDMI anti-interference transmission line based on multi-layer shielding, including a winding reel, an HDMI transmission line and a positioning component. The winding reel is surrounded by the HDMI transmission line, and the positioning component is sleeved around the HDMI transmission line.

[0006] The HDMI transmission cable includes a first shielding layer, a shielding braided mesh is disposed around the first shielding layer, an absorption layer is disposed between the first shielding layer and the shielding braided mesh, and a second shielding layer is disposed inside the first shielding layer.

[0007] By adopting the above technical solutions and adding multiple shielding structures, electromagnetic interference from external Wi-Fi, mobile phones, power supplies, and other devices can be greatly reduced.

[0008] Specifically, the positioning component includes a base plate, a corresponding sliding sleeve is provided on the top of the base plate, a Velcro female side is bonded to the top surface of the base plate, and a Velcro female side is bonded to the bottom surface of the sliding sleeve.

[0009] Specifically, the second shielding layer contains data lines and signal control lines, the first shielding layer contains a magnetic powder layer located outside the second shielding layer, and the shielding braided mesh is covered with a sheath.

[0010] Specifically, the surface of the sliding sleeve has through holes, through which the HDMI transmission cable passes, and mounting bases are fixedly installed on both sides of the base plate.

[0011] Specifically, both the first and second shielding layers are made of aluminum foil Mylar, and the absorption layer is a ferrite film.

[0012] The beneficial effects of this utility model are:

[0013] (1) The HDMI anti-interference transmission line based on multi-layer shielding described in this utility model increases the multi-layer shielding structure by setting a first shielding layer, a second shielding layer, a shielding braided mesh and an absorption layer. By using multi-layer shielding, electromagnetic interference from external Wi-Fi, mobile phones, power supplies and other devices can be greatly reduced, thereby improving the stability of the HDMI transmission line.

[0014] (2) The HDMI anti-interference transmission line based on multi-layer shielding described in this utility model can increase the auxiliary positioning structure by setting the base plate, sliding sleeve, hook and loop female side and hook and loop female side. By using the bonding and fixing method, the stability of the HDMI transmission line in actual use is improved, and it is less likely to be displaced by external force pulling. At the same time, it can also protect the end connectors and interfaces, making it more reasonable and reliable to use. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] To facilitate the use of multi-layer shielding to improve the anti-interference performance of HDMI transmission cables and thus enhance their performance, such as... Figure 1-3 As shown, the present invention provides an HDMI anti-interference transmission cable based on multi-layer shielding, which includes a winding reel 1, an HDMI transmission cable 2, and a positioning component 3. The winding reel 1 is surrounded by the HDMI transmission cable 2, and the positioning component 3 is sleeved around the periphery of the HDMI transmission cable 2.

[0023] The HDMI transmission cable 2 includes a first shielding layer 201, a shielding braided mesh 202 is provided around the first shielding layer 201, an absorption layer 203 is provided between the first shielding layer 201 and the shielding braided mesh 202, and a second shielding layer 205 is provided inside the first shielding layer 201.

[0024] In use, the first shielding layer 201, the second shielding layer 205, the shielding braided mesh 202 and the absorption layer 203 can increase the multiple shielding structure. By using the multi-layer shielding method, the electromagnetic interference of external equipment can be greatly reduced and the stability of use can be improved.

[0025] To improve stability in use, for example, such as Figure 1 , Figure 4 As shown, the present invention also includes a positioning component 3 comprising a base plate 301, a corresponding sliding sleeve 302 being provided on the top of the base plate 301, a Velcro female surface 303 being bonded to the top surface of the base plate 301, and a Velcro female surface 304 being bonded to the bottom surface of the sliding sleeve 302.

[0026] In use, the base plate 301, sliding sleeve 302, hook and loop female side 303 and hook and loop female side 304 can be used to increase the auxiliary positioning structure and improve the stability of the transmission line during use by means of bonding and fixing.

[0027] For example, such as Figure 2 , 3As shown, the present invention also includes a data line 204 and a signal control line 207 disposed in the second shielding layer 205, a magnetic powder layer 206 filled in the first shielding layer 201 outside the second shielding layer 205, and a sheath 208 covering the outer periphery of the shielding braided mesh 202.

[0028] When in use, the magnetic powder layer 206 can further improve the anti-interference performance of the transmission line. The second shielding layer 205 is equipped with a ground wire for grounding protection. The sheath 208 can form protection around the transmission line, improving the safety of use. The sheath 208 is made of PVC material, and the magnetic powder layer 206 is made of nano ferrite magnetic powder.

[0029] For example, such as Figure 4 As shown, the present invention also includes a through hole 305 on the surface of the sliding sleeve 302, through which the HDMI transmission cable 2 passes, and mounting bases 306 are fixedly provided on both sides of the base plate 301.

[0030] During use, the through hole 305 facilitates the connection of the sliding sleeve 302 to the HDMI transmission cable 2. The usage position can be adjusted according to actual usage needs. The mounting base 306 facilitates the use of the pre-drilled bolts to fix the mounting plate 301 for use.

[0031] For example, such as Figure 2 , 3 As shown, the present invention also includes, in which the first shielding layer 201 and the second shielding layer 205 are both aluminum foil Mylar, and the absorption layer 203 is a nickel-zinc ferrite film.

[0032] In use, the first shielding layer 201 and the second shielding layer 205 of the aluminum foil Mylar can reflect high-frequency interference, and the absorption layer 203 of the ferrite film can absorb the medium-frequency magnetic field. The shielding braided mesh 202 is an aluminum-magnesium alloy braided mesh.

[0033] When in use, this utility model can reflect external high-frequency interference through the first shielding layer 201 and the second shielding layer 205, while the absorption layer 203 can absorb the medium-frequency magnetic field, and the shielding braided mesh 202 can enhance the mechanical strength and low-frequency shielding effect of the transmission line. Through the added multi-layer shielding structure, the electromagnetic interference from external Wi-Fi, mobile phones, power supplies and other devices can be greatly reduced, the stability of the HDMI transmission line 2 can be improved, and the quality of data transmission can be guaranteed.

[0034] Furthermore, in actual use, the HDMI cable 2 can be pre-lengthened according to the length and needs, and the base plate 301 can be fixed by bolts through the mounting bracket 306. Then, the Velcro side 304 of the sliding sleeve 302 is used to bond the Velcro side 303 to form an auxiliary positioning mechanism. This not only reduces the positional displacement caused by external pulling and improves the stability of use, but also helps to improve the safety of the cable connector and interface. The structure is simple and compact, the cost is low, and the use is more reasonable and reliable.
