Problems solved by technology

[0003] Since the existing HDMI interface cables all use flat cables, the flat cables have poor compressive performance and bending performance. When in use, the internal structure is prone to slip when subjected to pressure or bending, resulting in damage to the line; In addition, the flat cable often causes unstable transmission signals due to its own and external interference; moreover, the transmission speed of the flat cable cannot meet people's expectations, and it will slow down the working speed in the use of large equipment, which is not suitable for people's use. Bring inconvenience, in order to improve the above-mentioned problems, Chinese patent publication number is CN208315227U discloses a kind of high-speed transmission cable for HDMI interface, relates to the field of transmission wire, including power cord set and set on the outer surface of power cord set from inside to outside The reinforcing layer, the braiding layer and the insulating protective layer, the insulating protective layer and the braiding layer are fitted and connected, the reinforcing layer includes the outer ring and the inner ring, the outer ring and the inner ring are evenly provided with reinforcing ribs, and the outer ring and the inner ring are arranged There is a connection block, which divides the space between the outer ring and the inner ring into several cavities on average, and a high-speed transmission line group is arranged in the cavity, and the high-speed transmission line group includes a pair of high-speed transmission lines and a transmission ground wire, and a power line group Including the power cord and the power ground wire, the utility model improves the shortcomings of the traditional HDMI cable, such as poor compression resistance and bending resistance, unstable transmission signal, and slow transmission rate. Not only the transmission rate is fast, but also the compression resistance and bending resistance Good, the transmission signal is stable and the transmission quality is high
[0004] Although the above-mentioned patents have better improved the flat cable's poor compressive performance and bending performance, and the internal structure is prone to slipping when it is under pressure or bending, it also complicates the cable protection skin at the same time. Leather processing is very unfavorable

Abstract

The invention discloses a flexible cable protective skin, belonging to the field of cable processing. The flexible cable protective skin comprises an inner protective layer, a special-shaped reinforcing interlayer and an outer protective layer which wrap the outer portion of a high-speed transmission conductor, the inner protective layer, the special-shaped reinforcing interlayer and the outer protective layer wrap the high-speed transmission conductor in order from inside to outside, the special-shaped reinforcing interlayer comprises a first special-shaped reinforcing layer and a second special-shaped reinforcing layer, the first special-shaped reinforcing layer wraps the surface of the inner protective layer, the second special-shaped reinforcing layer wraps the surface of the first special-shaped reinforcing layer, the outer protective layer comprises a temperature sensing insulation layer and a transparent layer, the temperature sensing insulation layer wraps the surface of the second special-shaped reinforcing layer, and the transparent layer wraps the surface of the temperature sensing insulation layer; and on the basis of not influencing the high-speed transmission, the compression resistance, bending resistance and internal anti-skid performance of the whole cable are integrated with the special-shaped reinforcing interlayer to simplify the whole cable and greatly simplify the processing process of the cable.

Description

technical field [0001] The invention relates to the field of cable processing, in particular to a flexible cable protective sheath. Background technique [0002] High Definition Multimedia Interface (English: High Definition Multimedia Interface, referred to as HDMI) is a fully digital video and sound transmission interface, which can send uncompressed audio and video signals. HDMI can be used in equipment such as set-top boxes, DVD players, personal computers, video game consoles, integrated amplifiers, digital audio and televisions. HDMI can send audio and video signals at the same time. Since the audio and video signals use the same wire, it greatly simplifies the installation difficulty of the system line. [0003] Since the existing HDMI interface cables all use flat cables, the flat cables have poor compressive performance and bending performance. When in use, the internal structure is prone to slip when subjected to pressure or bending, resulting in damage to the lin...
