Under the global "dual carbon" strategy and the trend of green manufacturing, connectors, as key components in industrial, electrical, automotive, and rail transit fields, are increasingly valued for their environmental performance. For domestically produced connectors, how to meet international environmental testing standards is a crucial link in moving towards the high-end market and achieving import substitution.

I. Reference to the environmental concept of the Conta-Clip brandConta-Clip is a German supplier of connector and electrical connection technology, offering products including terminal blocks, PCB connectors, cable management, identification systems, and control cabinet accessories. The brand always emphasizes in research and development design:
●Environmental protection compliance of materials: Insulating materials and metal parts selected in compliance with the EU RoHS (Restriction of Hazardous Substances) standard.
●Recyclable and Sustainable: Consider material recycling and lifecycle impact in product design to reduce industrial waste.
Halogen-free flame retardant and low smoke emission: Terminal products for control cabinets and electrical installations commonly use halogen-free flame retardant materials to reduce the risk of fire and secondary environmental harm.
These design concepts provide valuable reference for domestic connectors in terms of environmental protection testing and standard comparison.

The main standards for environmental testing of domestic connectors1. RoHS (Restriction of Hazardous Substances Directive)
●Limit the 10 harmful substances including lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls (PBB), and polybrominated diphenyl ethers (PBDE).
China-made connectors must pass this type of test to enter the international market.
2. REACH Regulation (Registration, Evaluation, Authorisation and Restriction of Chemicals)
●Involves hundreds of highly concerned substances (SVHC), such as phthalates, etc., with a focus on long-term environmental and health impacts.
3. Halogen-free standard (IEC 61249-2-21, etc.)
Detect the chlorine and bromine content in the material, requiring ≤900ppm, and total content ≤1500ppm, to ensure no corrosive gases are produced during combustion.
4. RoHS 2.0 & RoHS 3.0 Extended Standards
●Not only restricts more types of harmful substances, but also strengthens detection methods and traceability management.
5. Green Supply Chain Assessment (China Standard GB/T 24001)
●Involving environmental management of suppliers and assessment of product life cycle impacts is particularly crucial for domestic manufacturers.
6. Special Industry Standards
●Automotive industry: must meet ISO 11469 material marking and IMDS International Material Data System requirements.
● Railway transportation industry: must comply with EN 45545 flame retardant and low smoke standard.

Section 3: The Environmental Upgrade Direction of Domestic Connectors●Material Substitution: Adopting environmentally friendly flame-retardant nylon (PA66) and lead-free copper alloys to enhance sustainability.
●Certification: Promote domestic products to pass third-party environmental certifications such as SGS, TÜV, UL, etc.
Full-chain control: Fully integrate green concepts from design, material selection, production, to recycling.
●International Benchmarking: Draw on the modular design and eco-friendly material selection experience of Conta-Clip to enhance the competitiveness of domestic connectors in both export and domestic markets.

Domestic connectors need to truly achieve import substitution, not only by reaching international standards in electrical performance and structural strength, but also by strictly benchmarking environmental testing. By meeting core standards such as RoHS, REACH, and halogen-free, and learning from the experience of international brands like Conta-Clip, domestic connectors can seize opportunities in the green manufacturing wave and win more market trust.
