In modern precision electronic equipment, micro coaxial cable (极细同轴线束) is widely used in internal connection scenarios such as high-end laptops, high-definition cameras, medical instruments, and drone systems due to its extremely small size and excellent signal transmission performance. It is not only a "channel" for signal transmission but also a "hidden guardian" that ensures the high-speed and stable operation of the equipment. This article will combine the Hirose DF56L-26P-0.3SD connector to introduce in detail each key component of the internal structure of the micro coaxial cable.
Typical structure of extremely fine coaxial beam
A micro coaxial cable is usually composed of three major core parts:
Inner Conductor
The inner core is the main channel for signal transmission, directly determining the high speed and stability of the signal.
Common materials include silver-plated copper wire or high-purity copper wire to ensure low impedance, excellent electrical conductivity, and effectively reduce signal loss.
2. Shielding Layer
The shielding layer is a key link in resisting external electromagnetic interference (EMI) and preventing signal leakage.
通常采用silver-plated copper woven mesh or aluminum foil shielding structures, which can greatly enhance the anti-interference ability of the cable harness, ensuring the integrity of the signal during high-frequency and high-speed transmission.
3. Outer Jacket
The outer sheath provides mechanical and environmental protection for the cable, preventing wear, acid-base corrosion, and temperature shock.
Common materials include heat-resistant PVC (polyvinyl chloride) and FEP (fluoroplastic), which combine flexibility and high-temperature resistance, allowing cables to operate stably for a long time under complex working conditions.
Hirose DF56L-26P-0.3SD connector introduction
Among numerous connector brands, Hirose DF56L-26P-0.3SD stands out as a classic representative in the field of ultra-thin coaxial cable sets, thanks to its precise miniaturization design and high reliability performance.
Core Features:
Support for ultra-fine coaxial connector with 0.3mm pitch.
② 26Pin small structure design, easily adaptable to narrow spaces.
Exhibits excellent vibration resistance and heat resistance, ensuring long-term stability of high-frequency signals.
④ The insertion and removal life reaches up to thousands of times, with firm installation, especially suitable for applications with high requirements for connection stability, such as laptops, camera modules, medical equipment, etc.
The core, shielding layer, and outer sheath of micro coaxial cable, although structurally fine, each have their own functions and are indispensable. When high-quality cables are combined with excellent connectors (such as Hirose DF56L-26P-0.3SD), it can ensure the stable and unobstructed transmission of signals inside high-frequency, high-speed, and miniaturized equipment to the greatest extent.
