Description

Technical Field

[0001] The utility model relates to the technical field of AV cables, in particular to an AV cable with an anti-breaking function. Background Art

[0002] AV cable is a cable specially used to transmit audio and video signals, usually used to connect devices such as game consoles, computers, TVs, etc. The design and manufacture of these cables need to meet specific electrical and mechanical performance requirements to ensure the quality and reliability of signal transmission.

[0003] With the continuous advancement of technology and the changing needs of consumers, the types and specifications of AV cables are also increasing. From the early analog signal transmission to today's digital signal transmission, the technical content and requirements of AV cables are getting higher and higher. Therefore, the background introduction of AV cables also needs to take into account its history and technological development.

[0004] The structure of the AV cable will affect the overall performance during design. The flexibility of the AV cable is the most important factor affecting the user experience. If the AV cable is not flexible enough, the internal structure may break, and the following situations may also occur:

[0005] Easy to get tangled and knotted: AV cables that are not flexible enough tend to get tangled, which is not only not conducive to cable management, but may also interfere with signal transmission.

[0006] Easy to damage: AV cables that lack flexibility are more easily damaged when subjected to external forces, such as bending, folding or stepping on, which can cause the conductor inside the cable to break or the insulation layer to break, affecting the signal transmission quality.

[0007] Restrictions on device layout: Due to insufficient flexibility, AV cables may not be able to adapt to the special layout requirements of certain devices, which may affect normal use and installation.

[0008] Not conducive to long-term use: AV cables that are used for a long time are prone to fatigue and aging. If the cable itself lacks sufficient flexibility and durability, its service life will be greatly reduced.

[0009] Impact on user experience: The flexibility of the AV cable is directly related to the user experience. If the cable is too stiff or fragile, it will cause inconvenience and trouble to the user and reduce user satisfaction.

[0010] Therefore, we propose an AV cable with an anti-breaking function to solve the above-mentioned technical problems. Utility Model Content
