Our in-house Crown Spring technology is protected by multiple international patents. Insertion force is reduced by 60%, current capacity increased by 80%, and temperature rise after life testing stays below ΔT50°C — core figures most competitors cannot match.

Product Structure
The C.C.P. crown spring connector uses a unique ring-shaped spring structure. As the pin enters the socket, the crown spring wraps around it and makes contact, effectively increasing the number of contact points to optimize high-current transmission and improve stability.
Every connector is designed and manufactured in-house by C.C.P. and paired with industry-leading proprietary plating technology, ensuring reliability and durability across every application.
Five Advantages That Lead the Industry
The patented crown spring structure uses a ring-shaped design that effectively increases the number of contact points inside the socket, optimizing high current and improving stability.
C.C.P. high-current connectors are designed specifically for consumer products and deliver the best user experience: easy, effortless mating with reduced insertion force, and a special stabilizing design that prevents accidental detachment and loss of performance.
The third-generation C.C.P. crown spring connector is rated for more than 20,000 service cycles — more stable than anything else on the market.
The crown spring is not only exceptionally efficient, it also makes it possible to design the most space-efficient connectors with high current capacity.
A very low resistance high-current connector design keeps temperature rise and energy loss to an absolute minimum.
Connector Types
Available as a single-pin connector or a complete module solution — choose the design type that best fits your application.
Coaxial Type
Multi-channel, omnidirectional mating
For high-current solutions where space is extremely limited; the omnidirectional design makes mating more convenient
Stamped Type
Low cost, high volume
Can be mass produced at low unit cost, ideal for large-scale applications where cost reduction matters
Terminal Type
Multi-channel
For complex mating applications or high-current charging, providing a multi-channel solution
Wiring Methods
Three termination methods are available — choose the one that best suits your installation environment and requirements.
