Under high-frequency transmission, the full analysis of loss control for extremely thin coaxial cable harnesses With the rapid development of automotive electronics and intelligent technology, in-car signal transmission is no longer limited to traditional power distribution, but has evolved into high-bandwidth communication for high-speed data and high-definition video. Against this background, vehicle-grade extremely thin coaxial cable harnesses (Micro Coaxial Cable Harness) have emerged and become one of the indispensable core components of intelligent vehicles.
Automotive-grade ultra-fine coaxial cable assembly
"Automotive-grade ultra-fine coaxial cable assembly" can be divided into three key concepts:
Automotive-grade
Products representing the stringent standards of the automotive electronics industry (such as AEC-Q series certification) can operate stably for a long time in harsh environments such as high temperature, strong vibration, humidity changes, and electromagnetic interference.
Extremely thin coaxial cable
It is a coaxial cable with an extremely small diameter (usually 0.2mm to 1mm), internally consisting of a central conductor, insulation layer, shielding layer, and outer sheath, which can achieve stable transmission of high-speed signals in narrow spaces.
Cable harness
A cable assembly that integrates multiple extremely thin coaxial cables into a complete signal channel through processing and connector assembly.
In brief, the automotive-grade ultra-fine coaxial cable assembly combines high-frequency transmission performance with automotive-grade reliability, and is a precision interconnect solution specifically designed for automotive high-speed signal systems.
High density and high performance parallel
Extremely thin coaxial cables are renowned for their minimal outer diameter and precise structure, suitable for vehicle environments that are space-constrained and require high signal integrity. Their multilayer structure-including the central conductor, insulating medium, shielding layer, and outer sheath-is precisely designed and controlled to ensure excellent electromagnetic compatibility and signal integrity.
Common characteristic impedance is 45Ω or 50Ω, which can meet the application requirements of high-definition video, radar sensors, and high-speed data interfaces.
Excellent anti-interference capability
Compared with traditional wiring structures, ultra-fine coaxial cable bundles have a significant advantage in anti-interference. Each wire has an independent shielding layer, which can effectively resist external electromagnetic interference (EMI). Even in the complex interference environment of vehicle-mounted motors, electronic control units, and radar signals, it can maintain stable signals. This feature is crucial in automotive applications, ensuring the reliable operation of key modules such as cameras, surround-view systems, and ADAS.
Four, wide application and environmental adaptability
Automotive-grade ultra-fine coaxial cable束 is widely used in:
Car high-definition camera and surround-view system
Intelligent cockpit display and information entertainment system
Advanced Driver-Assistance Systems (ADAS)
Autonomous driving sensor and control module
In addition, its lightweight, high flexibility, and resistance to bending characteristics make it also suitable for medical imaging equipment, industrial testing instruments, and consumer electronic products that require extremely high signal quality.
Five, support future high-speed interfaces
With the gradual entry of high-speed interfaces such as USB4, Thunderbolt, and PCIe into the automotive application field, data transmission rates are continuously improving. Automotive-grade ultra-fine coaxial cable bundles, with their characteristics of low loss, low latency, and precise impedance matching, can support data rates of up to tens of Gbps, providing stable and high-speed signal channels for autonomous driving systems and in-car entertainment.
Automotive-grade ultra-fine coaxial cable harnesses are becoming the core interconnection solution for intelligent automotive electronic systems due to their compact size, excellent anti-interference capability, and high-speed transmission characteristics. They not only enhance the reliability of the in-vehicle signal chain but also lay a solid foundation for more complex electronic architectures and autonomous driving systems in the future.
