Overview:
Our OEM Precision Gold-Plated Stamped Antifatigue Connectors for Electric Vehicles are expertly engineered electrical components designed to deliver low contact resistance, exceptional corrosion protection, and superior mechanical endurance. Constructed from high-conductivity copper or brass alloys through advanced progressive-die stamping, these connectors incorporate antifatigue design features—such as optimized spring slots and relief cuts—to ensure consistent mating force over thousands of cycles. Following stamping, each contact surface is selectively plated with a controlled gold thickness to guarantee stable electrical performance and long-term durability in EV powertrain and battery applications. As full-service OEM manufacturers, we provide turnkey solutions from custom part design and tool development to precision stamping, plating, secondary processing, and final assembly—ensuring components that meet rigorous automotive standards and performance requirements.

Secondary Processing Services:
- Selective Gold Plating
Utilizes precision masking and automated plating rigs to deposit gold only on critical contact areas—minimizing precious metal usage while ensuring low contact resistance and outstanding corrosion resistance. - Nickel or Tin Underplate
Applies a uniform nickel or tin undercoat prior to gold plating to improve adhesion, prevent base-metal diffusion, and enhance wear resistance. - Precision Annealing
Controlled heat-treat cycles to relieve stamping-induced stresses and optimize spring-contact resilience, ensuring reliable mating force over extended cycles. - Laser Marking & Etching
High-resolution laser engraving for permanent part identification, date codes, or logos without compromising plating integrity or electrical performance.
Quality Assurance:
Our rigorous QA framework aligns with ISO 9001 and IATF 16949 automotive standards, ensuring each connector meets precise performance criteria:
- Dimensional Verification (CMM): Coordinate Measuring Machines confirm exact stamped geometries and tolerances to ±0.01 mm.
- Contact Resistance Testing: Automated milliohm testers validate low resistance (< 20 mΩ) under specified current loads to guarantee electrical efficiency.
- Plating Thickness Measurement: X-Ray Fluorescence (XRF) analyzers verify gold and underplate thicknesses against customer specifications.
- Fatigue & Spring-Force Testing: Custom fatigue rigs cycle connectors over 10,000+ mating operations to validate consistent contact force retention.
- Corrosion & Environmental Testing: Salt-spray (ASTM B117) and humidity chamber evaluations ensure plating adhesion and long-term resistance to oxidation.
- Surface Inspection: Automated optical scanning (AOI) detects any plating defects, burrs, or surface irregularities.
- Material Hardness & Conductivity Checks: Rockwell hardness testers and electrical conductivity meters confirm alloy integrity and performance.
