Explore our engineering-focused product portfolio. Designed for reliable data transmission, high mechanical durability, and optimal power delivery under demanding conditions.
A CCP (Contact Probe/Pogo Pin) Connector represents a pinnacle of miniature interconnect engineering. Built using a spring-actuated plunger mechanism housed inside a barrel, CCP connectors deliver continuous electrical contact that tolerates dynamic vibration, misalignment, and high mating cycles. Unlike traditional leaf spring contacts, a CCP connector compresses axially, allowing for high-density spacing (pitch) and vertical mating interfaces.
Our solutions incorporate advanced manufacturing techniques to balance contact force, current capacity, and mechanical wear. As top-tier Custom CCP Connector Manufacturers, we engineer the internal spring geometry, contact surface metallurgy (including hard-gold and palladium-nickel alloys), and outer housing materials to meet strict automotive, aerospace, and medical device standards.
CCP connectors are changing interconnection design paradigms across high-value markets. Our bespoke design services translate client challenges into rugged components.
For medical devices and diagnostic cradles, we utilize biocompatible plating and non-magnetic materials. Our custom connectors offer reliable performance during patient monitoring, imaging, and sterilization procedures (including autoclaving cycles).
Engineered for high current capability, our automotive-grade CCP connectors survive heavy vibration in battery packs, ADAS radar assemblies, and dynamic automated test systems (ATE). We build systems handling up to 40A per single contact line.
Providing waterproof performance (IPX7 & IPX8 rating) combined with low profiles, these connectors are the standard for premium smartwatches, VR/AR headsets, and TWS Bluetooth earbuds. They prevent sweat-induced corrosion and electrical shorts.
Shenzhen Rongqiangbin Electronic Hardware Co., Ltd. is located in Shenzhen, the leading city of the Guangdong-Hong Kong-Macao Greater Bay Area. Established in February 2011 in Songgang Street, Shenzhen, we specialize in the development, manufacturing, and supply of premium POGO PIN (spring thimble) connectors. Over more than a decade of research, development, and expansion, the company has become an industry leader.
Guided by our core principles of "Customer First, Integrity First," RQB maintains a strong POGO PIN industry technology production team. We hold the ISO9001:2015 international quality management system certification, supported by robust environmental control programs to supply RoHS and REACH-compliant components to international markets.
Our key customer base features prominent global brands: Honeywell, Samsung, SIEMENS AG, ZTE, 360, QCY, HAYLOU, Shanghai Laimu, Luxshare Group, Aoni Electronics, and Amphenol Group.

Connector development is keeping pace with smaller device dimensions and rising data rates. RQB remains at the forefront of spring contact technology, focusing on several key developmental pillars:
Traditional pogo pins were designed primarily for power interfaces. As wireless communications advance, we are engineering pogo pin blocks capable of handling high frequencies, up to 10 GHz with low insertion loss, suitable for 5G testing interfaces and antenna contacts.
With smart rings, health trackers, and implants demanding smaller components, our fabrication facilities can produce pins with a barrel diameter under 0.4mm. This allows engineers to place multiple high-density signal lines in tight spaces.
Sweat, environmental moisture, and saltwater can degrade plating. We offer custom composite plating finishes, such as platinum (Pt), palladium-nickel (Pd-Ni), and customized gold layers, ensuring long-term contact stability without degradation.
We combine mechanical pogo pins with custom-molded magnetic shells to provide plug-and-play charging interfaces. These systems guide themselves into alignment and detach easily under excess tension, helping protect device chassis ports from structural damage.
Securing reliable high-volume components requires clean shipping logistics and verified compliance. RQB aligns with international quality frameworks to support customers' import workflows.
Every batch of custom CCP products is produced to meet RoHS Directive (EU) 2015/863 and REACH regulations. We also offer halogen-free materials and procure conflict-free minerals to support sustainable supply chain requirements.
We know that off-the-shelf parts don't always fit. RQB provides technical FAE consulting to review mechanical drawings, perform tolerance stack-up analyses, and run FEA spring simulations before launching mass-production tooling.
Deep technical insights compiled by our lead R&D engineers to answer common custom connector design inquiries.
Plungers are typically turned from brass or beryllium copper (BeCu) for high electrical conductivity, then plated with gold over nickel. Barrels are generally made from phosphor bronze or brass. Springs are wound from high-carbon music wire or stainless steel (SUS304/SUS316) to provide consistent spring rates and resistance to mechanical fatigue over high operating cycles.
Plating thickness directly determines wear resistance. Standard applications use 3 to 10 micro-inches of gold (Au) plating. For high-cycle consumer electronics (like smartwatches or cradles) or environments exposed to moisture, we can supply up to 30 to 50 micro-inches of hard gold over a nickel underplate, protecting the contacts against oxidation and abrasive wear.
Yes, we specialize in complete magnetic adapter assemblies. Our engineering team designs the plastics, magnets (usually Neodymium N52 grade), and CCP arrays together to match your housing. This ensures proper alignment force and polarity keying while preventing accidental electrical shorts.
We adjust the internal geometry of the plunger. Using a biased-plunger design (cut at an angle) or including an internal ball/sleeve configuration forces the plunger to remain in contact with the barrel wall. This lowers contact resistance and prevents high-current spikes from damaging the internal spring.
