Technical Field

[0001] This utility model relates to the field of cable structure technology, specifically to an HDMI cable structure that reduces signal reflection. Background Technology

[0002] HDMI cables are digital transmission interface cables used to connect high-definition display devices and high-definition signal source devices (such as TVs, monitors, projectors, computers, game consoles, DVD players, etc.).

[0003] The existing HDMI cable structure cannot reduce radiation interference and signal reflection, the signal is easily attenuated, and it cannot prevent damage to the connection between the main cable and the male and female connectors due to bending and pulling. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides an HDMI cable structure that reduces signal reflection. The HDMI cable structure reduces radiation interference and signal reflection, thereby reducing signal attenuation and preventing damage to the connection between the main cable and the male and female connectors due to bending and pulling.

[0005] The technical solution adopted by this utility model to solve its technical problem is an HDMI cable structure that reduces signal reflection, including a male connector, a main body and a female connector. The two ends of the main body are respectively connected to the male connector and the female connector. One end of the male connector and the female connector are provided with a positioning cover. One end of the positioning cover is connected to a guide sleeve. The two ends of the main body and the part that is close to the male connector and the female connector are heat-fused to a thickened tail sleeve.

[0006] The main body includes an outer sheath layer located on the outside, and a magnetic winding tape is provided on the inner surface of the outer sheath layer. A tensile braided layer is provided between the magnetic winding tape and the outer sheath layer. A silicone rubber tightening layer is provided on the inner surface of the magnetic winding tape. Single-core wires are evenly distributed on the inner side of the silicone rubber tightening layer, and an aluminum foil layer is provided on the outer surface of the single-core wires.

[0007] By adopting the above technical solutions, the HDMI cable structure reduces radiation interference and signal reflection, thereby reducing signal attenuation and preventing damage to the connection between the main cable and the male and female connectors due to bending and pulling.

[0008] Specifically, the two ends of the positioning cover are heat-fused together with connecting pieces, and the connecting pieces are fixed to the male and female seats respectively by positioning screws.

[0009] By adopting the above technical solution, the positioning cover facilitates the limiting of the thickened sleeve at the end of the main line, making installation and disassembly easier.

[0010] Specifically, the outer sheath is made of butyl rubber material, and the tensile braided layer is a Kevlar fiber layer.

[0011] Specifically, the single-core wire has an internal electronic wire.

[0012] By adopting the above technical solution, the electronic wire is responsible for transmitting video, audio, and control signals, ensuring the accurate and stable transmission of high-definition multimedia content.

[0013] Specifically, the two ends of the main line body are penetrated by guide sleeves and positioning covers, and the thickened sleeve at the end of the line is located inside the positioning cover.

[0014] The beneficial effects of this utility model are:

[0015] (1) The HDMI cable structure for reducing signal reflection described in this utility model uses the positioning cover at one end of the male and female connectors to limit the thickened sleeve at the end of the cable, avoiding damage caused by bending and turning for a long time. When the main cable is pulled, the thickened sleeve at the end of the cable is limited inside the positioning cover to avoid damage. The electromagnetic shielding effect is greatly improved by using the aluminum foil layer and magnetic wrapping tape on the outside of the single core wire to reduce radiation interference and signal reflection, thereby reducing signal attenuation.

[0016] (2) The HDMI cable structure for reducing signal reflection described in this utility model is made of butyl rubber material for the outer sheath, which is wear-resistant, does not easily scratch the outer surface, is corrosion-resistant, and durable. The tensile braided layer is specifically a Kevlar fiber layer, which effectively increases the tensile strength of the main cable, is not easy to break, and improves the performance.

[0033] During use, the guide sleeve 3 connects and guides the main line body 4, and the positioning cover 2 limits the position of the thickened sleeve 7 at the end of the line.

[0034] In use, the positioning cover 2 at one end of the male seat 1 and the female seat 5 limits the thickened sleeve 7 at the end of the wire, preventing damage caused by prolonged bending and turning. When the main wire 4 is pulled, the thickened sleeve 7 at the end of the wire is limited in the positioning cover 2, thus preventing damage from pulling.

[0035] By utilizing the aluminum foil layer 14 on the outside of the single-core wire 13 and the magnetic winding tape 10, the electromagnetic shielding effect is greatly improved, thereby reducing radiation interference and signal reflection, and thus reducing signal attenuation.
