Hummel is a professional connector manufacturer from Germany, whose products cover circular connectors from M8 to M40, hybrid connectors (Hybrid), and the high-protection INOX series. Hummel's products are renowned for their high reliability, resistance to environmental interference, and modular flexible design, and are widely used in industries such as industrial automation, robotics, new energy, transportation, and telecommunications. Particularly in EMC electromagnetic compatibility design and protection grades such as IP67/IP69K, Hummel products demonstrate strong technical advantages.
Quality Control Challenges of Domestic ConnectorsTo achieve domestic substitution for imported brands like Hummel, domestic connectors must pay sufficient attention to quality control. Common quality risk points include:
● Material selection: Whether the conductor material, insulator, and surface coating meet the long-term stability requirements;
●Processing technology: Insufficient precision may lead to shortened insertion and extraction life and increased contact resistance.
● Consistency: How to ensure stable performance in each batch of mass production.
● Reliability: Whether it can maintain performance in harsh environments such as vibration, humidity, and high temperature.
Quality Control Tools and Methods SharingMaterial Analysis and Verification
●Through spectral analysis and scanning electron microscopy, detect the composition of materials to ensure that both the metal and plastic parts meet the standards.
Electrical Performance Testing
●Conduct contact resistance, insulation resistance, and voltage withstand tests to verify the electrical stability of the connector.
Environmental and Lifespan Test
●Tested by salt spray test, cold and hot shock test, vibration and impact test, simulating the usage scenarios of Hummel products.
●Insertion and extraction life test to ensure that the connector can achieve stable insertion and extraction for 500 times even up to 1000 times or more.
4. EMC Shielding Effect Verification
●Following Hummel's design ideas in EMC, conduct 360° shielding effectiveness detection to ensure that domestic products can effectively suppress electromagnetic interference.
5. Process Control and Traceability System
●Introduce tools such as SPC (Statistical Process Control) and FMEA (Failure Mode and Effects Analysis) in the production process to enhance process stability.
Improve the batch traceability system to ensure that issues can be quickly located and corrected.
Hummel connectors have established an industry benchmark with their exquisite manufacturing process and strict quality control system. For domestic connectors to achieve import substitution in the high-end market, they must combine scientific quality tools and methods, strengthen material testing, electrical performance verification, environmental testing, and process control in order to truly achieve reliable performance and stable quality.
