Würth connector domestic substitute technology analysis

At present, with the rapid development of the electronic manufacturing industry, connectors, as key components for realizing electrical connections and signal transmission, have become an important part of system design in terms of quality and reliability. In recent years, the well-known German connector brand Würth Elektronik (Würth Electronic) has been continuously playing a leading role in technical aspects in high-demand applications such as industry, automotive electronics, and communication. Its series of high-precision and high-stable connectors are widely used in complex working conditions, posing a significant challenge to domestic connector manufacturers.

Domestic Connectors: Three Technological Breakthroughs Behind the Quality Improvement
Faced with technical barriers of imported brands, domestic connector manufacturers have continuously achieved independent technological upgrades in recent years, gradually narrowing the gap with brands like Würth Elektronik, especially making key breakthroughs in the following aspects:
Enhancement of high temperature and high pressure resistance performance
National brands achieve the ability of connectors to work stably at temperatures above +125℃ by using high-temperature and high-strength engineering plastics (such as PBT, LCP) and gold or tin plated terminal processing technologies. These connectors can pass various high-temperature aging tests and thermal shock tests, gradually meeting the requirements of industrial and automotive fields.
Insertion and extraction life and structural design optimization
Structural precision and process stability have been the shortcomings of domestic connectors in the past. Now, some domestic manufacturers have introduced high-precision molds, automated assembly, and displacement detection technology, which has increased the plug and pull life of the product to more than 5000 times. The lock structure is tighter and more wear-resistant, suitable for industrial control systems with frequent plug and pull operations.
Electrical performance and EMI shielding technology are mature.

In response to the requirements for high-speed transmission and signal integrity, an increasing number of domestically produced connectors are adopting multi-layer grounding design, metal shielding structures, and optimized PCB pad layouts. This significantly reduces crosstalk and reflection interference while achieving electrical compatibility with mainstream standards (such as USB 3.1, PCIe Gen4).
