Ultra-fine coaxial cable assembly solution for high-speed device connection requirementsWith the continuous development of AI devices, industrial cameras, high-definition display devices, smart terminals, and high-speed computing devices, internal signal transmission puts higher requirements on the miniaturization, high-speed performance, and anti-interference ability of cables. The ultra-fine coaxial cable, with its fine diameter structure, excellent impedance control capability, and good electromagnetic shielding performance, has become an important solution for high-density electronic device internal high-speed signal connections. In terms of the I-PEX CABLINE®-CA series 40Pin ultra-fine coaxial cable solution, our company can independently design and manufacture according to the original factory specifications, providing domestically produced, high-reliability compatible alternative products. Among them, the I-PEX 81424-100B-02-D ultra-fine coaxial cable adopts a 40Pin Micro-Coaxial structure scheme, with a cable length of 200MM, and the wire end is matched with the connector model 20634-140T-02, which can meet the needs of engineering development, mass production, and supply chain replacement. Our company can provide compatible alternative cable solutions for I-PEX 81424-100B-02-D to help customers reduce procurement costs and improve supply chain stability.
How is electromagnetic interference suppressed in ultra-fine coaxial束?One of the biggest challenges for engineers in high-speed signal transmission is the control of electromagnetic interference (EMI). Extremely fine coaxial cables can effectively reduce the impact of EMI, mainly relying on their special coaxial structural design. Compared to ordinary wires, extremely fine coaxial cables use a multi-layer structure composed of a central conductor, an insulating layer, a shielding layer, and an outer sheath. The shielding layer can form a 360° surrounding protection, effectively blocking external electromagnetic signals from affecting internal high-speed differential signals and simultaneously reducing the radiation of their own high-speed signals outward.
In the I-PEX CABLINE®-CA series connection solution, the connector end adopts a shielding structure and multi-point grounding design, allowing the cable shielding layer to form a stable connection with the connector metal structure, thereby further enhancing the overall EMI protection capability. For I-PEX 81424-100B-02-D and other 40Pin high-speed ultra-thin coaxial cable types, in high-speed signal application environments such as USB, DisplayPort, eDP, MIPI, etc., a good shielding design can reduce crosstalk, reduce signal attenuation, and improve system operation stability.
The design advantages of ultra-fine coaxial beam from the perspective of engineering applicationsIn the product design phase, engineers not only focus on whether the harness can achieve signal connection, but also pay attention to signal integrity, space occupation, and long-term reliability during high-speed transmission. The I-PEX 81424-100B-02-D ultra-thin coaxial cable harness adopts a 40Pin Micro-Coaxial cable material scheme,配合 20634-140T-02 connector, which can meet the internal connection needs of high-density, small space equipment. The 200MM length design can be suitable for flexible wiring between internal modules of equipment, while reducing the space pressure brought by traditional cables.
The advantages of extremely thin coaxial cable bundles in high-speed applications are not only reflected in their anti-EMI capability, but also include more stable characteristic impedance control, lower signal loss, and better differential signal consistency. Through reasonable design of conductor size, insulation material thickness, shielding layer structure, and manufacturing processes, the continuity of impedance during signal transmission can be ensured, avoiding reflection, degradation of eye diagrams, and communication anomalies caused by impedance changes.
