Product Description Technical information Engineering difficulty

Terminal connector used in socket or battery

1. Material: Brass;
2. Surface treatment: Nickel plating;
3. Process: Progressive stamping --- Nickel plating

1. Size is small as 30*5*15 mm,
2. Structure is complex;
3. precision only accept +/-0.05mm tolerance.

Spring contact used in battery

1. Material: Spring steel;
2. Surface treatment: Nickel over copper plating;
3. Process: Progressive Stamping --- Heat treatment --- Nickel over copper plating

1. Usually nickel plating thickness is 3 to 5 μm, this part requires 8-10μm copper plating and 7-8μm nickel plating;
2. Should pass 24H salt spraying testing, without anti rust oil;
3. Very Elastic, side lips won't be broken after bended 90°oppositely.
4. Workable for high shear force, after soldered on PCB, won't be separated from PCB even apply 900N force.
