Structural Components: Science Behind Every Detail
- Shell: Nickel-plated copper alloy for superior EMC shielding and mechanical protection.
- Insulator: High-performance PA66+GF ensures insulation and stability.
- Contacts: Gold-plated copper alloy for excellent conductivity and corrosion resistance.
- Sealing Ring: Silicone material for waterproof and dustproof performance.
- Locking Mechanism: Threaded or quick-lock design to prevent loosening.
How Does It Work?
- Electrical Contact: Pins and sockets tightly fit to form a low-resistance path.
- Mechanical Positioning: Keying and thread-locking ensure accurate connection.
- Signal Transmission: Contacts provide stable conductivity with resistance ≤5mΩ.
- EMI Shielding: Metal shell and ground layer prevent electromagnetic interference.
