Description

Technical Field

[0001] This utility model belongs to the field of cable fixing technology, and in particular relates to a network cable clamping device for broadcasting and television engineering. Background Technology

[0002] Broadcast and television engineering mainly utilizes computer software and modern electronic technology for information processing, focusing on audio and video processing, source compression, film and television production and program management, program broadcasting and distribution, etc. Network cables refer to network connection lines, which are the medium for transmitting information from one network device (such as a computer) to another network device. They are the basic components of a network. In order to facilitate the organization of network cables, they are clamped or glued after wiring.

[0003] However, existing cable clamping devices do not allow for easy adjustment of the cable tension, leading to a series of problems during use. For example, if the cable is too tight, it may compress the internal conductors, affecting the stability of signal transmission or causing physical damage to the cable and its connections. Conversely, if the clamp is too loose, the cable may slip or even fall off during use, creating potential safety hazards and operational inconvenience. Utility Model Content

[0004] The purpose of this utility model is to provide a network cable clamping device for broadcasting and television engineering. By setting an adjustment mechanism, the tightness of the cable can be adjusted to avoid the cable becoming loose during the wiring process due to excessive looseness. This solves the problem that existing cable clamping devices are not convenient for adjusting the tightness of the cable when clamping it, which leads to a series of problems during the use of the cable clamping device.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a network cable clamping device for broadcasting and television engineering, including a side plate and a cable.
