In today’s rapidly advancing era of industrial automation, control cabinets serve as the “nerve center” of equipment operation; therefore, the selection of internal wiring harnesses directly affects the system’s stability, safety, and maintenance efficiency. From automotive welding lines to smart agricultural machinery, from new-energy storage systems to precision medical devices, different application scenarios place varying demands on the performance of wiring harnesses—such as temperature resistance, anti-interference capability, and mechanical strength. This article, drawing on industry practices and authoritative standards, elucidates the six core principles for selecting wiring harnesses in industrial control cabinets.

As a core component in electronic devices responsible for transmitting signals and energy, the crimping quality of wire harnesses directly affects product performance and safety. Poor crimping can lead to increased contact resistance, signal attenuation, and even short circuits, making it a common pain point in the electronics manufacturing industry. This article systematically analyzes the root causes of poor wire harness crimping from four key perspectives—materials, processes, equipment, and management—and proposes targeted solutions.

Driven by the wave of Industry 4.0 and intelligent manufacturing, industrial connectors—key components for device interconnection—are undergoing a profound transformation from “passive connectivity” to “proactive intelligence.” This technological evolution not only meets the reliability requirements of traditional industrial applications but also increasingly integrates into emerging fields such as new energy, robotics, and rail transit, giving rise to three major core development trends: **intelligence, miniaturization, and high speed.** These trends represent both an adaptive evolution to harsh environments and a proactive response to the explosive growth of industrial data, collectively outlining the technological roadmap for future industrial connectors.
