FAQS

FAQs of Electrical Connector Pin

What types of charging connector pins does AUPINS mainly produce?

We specialize in manufacturing electrical connection terminals that meet mainstream standards. Our main product types include EV charging Connector Pins, hyperboloid contacts, and crown spring pins, offering diverse structures to meet different design needs.

Which international or industry standards do your products comply with?

Our terminals strictly adhere to the structural, dimensional, and performance requirements of standards such as IEC, SAE, GBT, and Tesla NACS, ensuring compatibility and reliability with mainstream global charging interfaces.

Can these connector pins be customized?

Yes, customization is our core service. We can make specific adjustments to key parameters such as insertion and extraction force, contact resistance, and plating processes according to your specific requirements to meet the most stringent needs of high-end customers.

What materials are used for the contact plating of your products? Why?

We primarily use silver or gold as plating materials. These precious metal platings effectively reduce contact resistance, enhance corrosion resistance and conductivity stability, thereby ensuring the long-term reliability and safety of the connector under high current transmission.

How do you ensure the electrical performance and durability of your products?

We control insertion and extraction forces and contact resistance through precision manufacturing processes to ensure stable and reliable connections every time. Specific plating processes further guarantee the terminals' resistance to wear and oxidation, extending their service life.

How do I begin collaboration if I have specific design requirements?

Please contact us directly and provide your technical specifications. Our engineering team will assess the feasibility of customization in terms of structure, dimensions, performance, and plating processes, and provide you with professional solutions and sample support.
