In the design of high-speed data transmission and compact electronic equipment interconnection, the ultra-fine coaxial wire harness, as a high-performance connection solution, is widely used in the fields of communication, computer, automotive electronics and so on with its excellent signal integrity, flexible layout and shielding performance. Typical representative products such as I-PEX 81786-100B-02-D series very thin coaxial harness assembly, has become many engineers in the high-speed interconnection scene of the preferred standard parts.

As the industry's demand for delivery, cost and customization increases, our team, based on rigorous R & D and manufacturing capabilities, has introduced alternative coaxial harness assembly solutions compatible with this model to provide customers with more flexible selection support.

1. product background and technical value

I-PEX 81786-100B-02-D is part of CABLINE®-CA Series Very Fine Coaxial Harness Assembly features:

1.1, 20-bit plug-to-plug interconnection structure, 0.4mm pitch design, suitable for micro-pitch high-speed data connection;

1.2, fully shielded extremely fine coaxial line design, effectively suppress electromagnetic interference, improve signal integrity;

1.3. With lock structure to improve the stability of mechanical connection, suitable for industrial and mobile scenes.

Very fine coaxial wire harness essentially realizes high-frequency signal transmission through small diameter coaxial cable. The center conductor and multi-layer shielding structure work together to maintain impedance matching and noise suppression. It is an important interconnection component to meet the requirements of high-speed (>Gbps) transmission and high EMI immunity.

2. engineering selection logic analysis

In the selection process, engineers are usually concerned with the following core parameters:

2.1. Signal rate and impedance control:

Very thin coaxial bundles need to meet a specific impedance design (such as 50Ω center impedance) to ensure that the reflection loss of high-speed signals during transmission is minimized. According to the signal rate and harness length of the target application, we use the micro coaxial cable specifications corresponding to the I-PEX to design to meet the signal integrity requirements.

2.2, mechanical and connection reliability:

The I-PEX series has the advantages of mechanical locking and structured wiring harness layout to ensure the stability of plugging and unplugging. In the alternative design, we achieve the equivalent of mechanical structure and locking scheme to ensure interchangeability and connection performance.

2.3, customized length and termination process:

In actual product assembly, different equipment has different requirements for harness length, termination direction and bending radius. We support a variety of customization options and optimize the termination process with engineering commissioning feedback to reduce assembly difficulty and improve product consistency.
