A ultra-fine coaxial cable assembly solution for high-speed device connection requirements

With the continuous development of laptop computers, high-speed display devices, AI intelligent terminals, industrial vision equipment, robots, and high-performance computing equipment towards thinness and high-speed performance, the internal space of the devices is becoming increasingly compact. At the same time, there is an increasing demand for high-speed signal transmission, electromagnetic interference resistance, and reliable connections. Traditional cable harness solutions often encounter problems such as signal attenuation, increased crosstalk, and insufficient long-term reliability when facing high-density, small spaces, and high-speed signal environments.

How to improve the broken wire problem of extremely fine coaxial cable束? Improve product reliability from manufacturing technology.

In practical applications, extremely thin coaxial cable assemblies, due to their very fine wire diameter and smaller internal conductor size, are more sensitive to bending, pulling, and assembly stress compared to ordinary cable assemblies. Therefore, "How to improve the breakage problem of extremely thin coaxial cable assemblies" has become a key issue of focus for engineering designers and procurement personnel.

The occurrence of断裂 in extremely thin coaxial cable bundles is usually related to the following factors: excessively small bending radius of the cable bundle, excessive stretching during assembly, abnormal force on the terminal crimping area, unreasonable wire fixing method, as well as mechanical fatigue caused by long-term vibration environment.

In response to these issues, our company has improved the long-term reliability of products in the manufacturing process of extremely fine coaxial cable assemblies by optimizing the production process and quality control system.

In the cable processing stage, select suitable stripping, termination, and processing parameters based on different AWG specifications to avoid internal conductor damage due to excessive processing pressure; during the cable shaping process, strictly control the bending angle and cable layout to reduce local stress concentration; in the connector assembly process, strengthen quality control of the terminal connection area to lower the potential wire break risk caused by contact area stress.

At the same time, it is recommended that engineers reasonably plan the cable routing during the product design stage, avoid sharp angle bends, reserve sufficient bending space, and combine with the actual vibration environment of the equipment for reliability evaluation.

Through material selection, process optimization, and structural design improvement, the probability of wire breakage in ultra-fine coaxial cables can be effectively reduced, thereby improving product lifespan and equipment operation stability.

Four, selection and compatibility and alternative solutions reference and suggestions

For customers engaged in product upgrades, domestic substitution, or supply chain optimization, when selecting ultra-fine coaxial cable solutions, it is necessary to comprehensively consider the connector model, wire material AWG specification, transmission performance, mechanical space, and bulk supply capability.

In response to the application requirements for the I-PEX 82981-100B-01-D, it is recommended to refer to the following compatible selection directions:

The 20Pin ultra-fine coaxial cable harness scheme using the 20634-120T-02 cable end connector can be used as an alternative reference solution for CABLINE-CA series applications. According to different product requirements, 36AWG, 38AWG, 40AWG, 42AWG, and 44AWG ultra-fine coaxial wires can be selected for matching.

If the customer focuses on high-speed signal integrity, such as applications in high-speed display, industrial cameras, and AI vision equipment, it is recommended to prioritize wire solutions with a performance grade of 40AWG or higher; if the customer is more concerned about flexibility, spatial layout, and assembly convenience, it can combine the equipment structure to choose a more suitable wire diameter specification.

In the localization replacement project, it is recommended that the engineering team confirm the following key parameters in advance: connector model matching, pin count, pin definition, cable length, bending requirements, operating environment temperature, and reliability test standards.
