In the fields of new energy vehicles, industrial automation, rail transit, and power equipment, the stability and reliability of connectors directly determine the safety and lifespan of the system. As an internationally renowned energy management and automation brand, Schneider (Schneider Electric) has been deeply involved in the fields of low-voltage electrical, industrial control, and system interconnection for a long time. Its connection solutions emphasize safety, modularity, and high reliability.
With the increasing demand for domestic substitution in the domestic market, how to establish a set of testing process standards that meet international standards has become a key factor for whether domestic connector manufacturers can quickly enter and stabilize the supply chain.
First, the key links of the domestic connector testing process standardAppearance and size inspection
Detect connector appearance defects and dimensional deviations through precise measuring tools to ensure consistency with design drawings. For domestic substitute products, it is necessary to maintain interface consistency and interchangeability with international brands (such as Schneider).
Electrical Performance Testing
Contact Resistance: Ensure stable conductivity performance.
Insulation resistance and voltage withstand: Ensuring safety under high-voltage environments.
Current carrying capacity: Simulate high current applications, prevent failure due to overheating.
Mechanical property test
Insertion-extraction life test: Simulating reliability after long-term use.
Vibration and shock testing: Rigorous conditions for automotive and industrial environments.
Keep-alive test: verify the stability of the clip or locking structure under high-frequency vibration.
Environmental adaptability test
High and low temperature cycle: Test the thermal stability of the material.
Moisture aging test: Test the insulation reliability under a humid environment.
Salt spray test: examines durability in corrosive environments.
Signal integrity and EMC testing
With the complexity of new energy BMS, intelligent manufacturing, and communication interfaces, connectors need to maintain low loss and low crosstalk under high-speed signals, and have good electromagnetic compatibility.
Part Two: Schneider's Experience and Insights for Domestic StandardsSchneider emphasizes modularization, standardization, and maintainability in automation and electrical systems, which is of reference significance for domestic connector manufacturers in formulating testing procedures:
● Modular interface testing: Domestic manufacturers can learn from Schneider's modular interface concept to ensure that products are easier to integrate and replace.
Robust environmental adaptability: Verification under high temperature, high humidity, and vibration environments can enhance the competitiveness of domestic products in the field of new energy vehicle BMS and industrial applications.
●System-level reliability: It is not only about meeting the standard of single performance, but also aims to promote the overall system safety, enabling domestic connectors to have a stronger voice in the international market.
The establishment of domestic connector testing standards is not only to meet customer requirements but also the inevitable path to entering the international market and competing with international brands like Schneider. Only through standardized and systematic testing can domestic connectors truly achieve reliable replacement in new energy vehicles, electrical systems, and industrial applications.
