In industries such as electronics, communication, and industrial manufacturing, connectors act as important bridges for signal and power transmission, and their quality directly affects the performance and stability of the entire equipment. MH Connectors is a professional connector brand under the British EDAC Group, which has been focusing on the research and manufacturing of products such as D-Sub connectors, Hoods, and RJ modular connectors since its establishment in 1985, known for its reliable quality and efficient assembly solutions. With the acceleration of the domestic substitution trend, how to scientifically formulate the customer acceptance standards for domestic connectors has become a key factor for enterprises to ensure supply chain safety and product quality.
Product features of MH Connectors●D-Sub series: Covers 9 to 62 pins, offering gold flash镀 or gold-plated contacts, supporting various welding methods to meet different signal transmission requirements.
● Metal and Plastic Hoods: Featuring EMI/RFI shielding performance, balancing stress relief and ease of installation.
● RJ modular interface: Suitable for RJ45, RJ11 and other standard interfaces, compatible with shielded and unshielded applications, widely used in communication and network equipment.
● Wide temperature adaptability: Some series can maintain stable performance in extreme environments ranging from -40°C to +120°C.
These characteristics provide an excellent reference template for the standardization of domestically produced substitute products.
Establishment method of domestic connector customer acceptance standardsDefine industry application requirements
Establish key performance indicators for target industries (such as communication equipment, industrial control, and medical electronics), such as electrical contact stability, EMI shielding performance, mechanical strength, and service life.
Refer to international brand performance benchmarks
Drawing on the mature experience of MH Connectors in material selection, surface plating (gold/gold flash), stress relief, and shielding structure, as the benchmark for domestic products.
Establish a detection and verification process
Electrical test: insertion and extraction life, resistance fluctuation, and signal integrity.
●Environmental test: High and low temperature cycle, humidity and vibration shock.
● Shielding performance test: Verify the EMI/RFI suppression capability.
4. Dimension and Compatibility Inspection
Check whether the domestic substitute products are compatible with the dimensions, pitch, and shell thread of MH Connectors to ensure interchangeability and assembly stability.
5. Consistency of appearance and craftsmanship
The shell should be free of visible scratches and coating defects, with clear markings, and after assembly, it should meet the standard of appearance consistency.
6. Quality System and Supply Chain Assurance
Establish a full-process traceability system from material procurement to process control, in accordance with ISO or IPC international standards, to ensure batch consistency and long-term stable supply.
Under the background of accelerating domestic substitution, formulating scientific customer acceptance standards is not only a necessary condition for ensuring quality, but also an important means to win customer trust and enhance market competitiveness. By referring to the mature product design and performance standards of MH Connectors, domestic connectors can fully achieve a comprehensive breakthrough in reliability, compatibility, and cost-performance.
