With the rapid development of intelligent vehicle technology, the central control screen has long become the core module of in-car interaction. In order to ensure high-definition images, synchronized audio and video, and stable transmission of multiple information, car manufacturers are increasingly inclined to use extremely thin coaxial cables (micro coaxial cable) for the internal signal transmission harnesses of the central control screen. So, what makes the extremely thin coaxial cable harness the preferred choice for the central control screen? This article will provide a detailed explanation and introduce a high-performance connector - I-PEX 20373-R40T-06, as well as a professional extremely thin coaxial cable harness customization solution.
What is micro coaxial cable (micro coaxial cable)?
The ultra-fine coaxial cable is composed of the inner conductor, insulating layer, shielding layer, and outer sheath, and it is a high-frequency transmission line. Its characteristics include extremely thin wire diameter, excellent shielding performance, and low signal loss, and it is widely used in scenarios with high requirements for signal stability such as high-definition displays, camera modules, car audio and video systems, and medical equipment. In the application of car central control screens, with the resolution upgraded from 720P, 1080P to 4K and even 8K, higher requirements are put forward for the transmission speed, EMI anti-interference ability, flexibility, and spatial adaptability of the signal cables. Standard parallel cables and standard coaxial cables are difficult to meet the needs, while micro coaxial cable has obvious advantages:
High-speed transmission: Supports data rates above 20Gbps.
Strong anti-interference: Excellent electromagnetic interference (EMI) protection capability.
Flexible cabling: Suitable for layout in narrow vehicle spaces.
Lightweight design: In line with the automotive lightweighting trend.
