KRCONN has successfully developed an IPX5‑rated waterproof Type‑C female connector.

Krconn has newly launched the high‑protection, everyday‑waterproof Type‑C connector (model: TWR26-60111605-05). As a next‑generation, highly efficient interconnect solution, this product seamlessly integrates an innovative all‑over‑mold waterproofing process with a high‑density double‑wave pressure‑sealing ring technology, breaking through the dual bottlenecks of high cost and complex structure that have long plagued traditional waterproof connectors. Within an extremely compact physical footprint—total height just 6.00 mm—this connector delivers outstanding electrical performance and exceptional mechanical durability. Coupled with a flexible post‑assembly dispensing upgrade option, its waterproof protection rating can be boosted to the highest IPX7 immersion level after surface‑mount assembly. Designed to offer unparalleled value, this product builds a robust, reliable waterproof and dustproof barrier for smart wearables, consumer electronics, and various outdoor smart devices.

CHP05-D34-0017 - Stamping and Drawing Charging PIN

In response to the high-frequency contact demands of smart wearable devices and TWS Bluetooth earphone charging contacts—prone to electrolytic corrosion from sweat—and the stringent requirements of large-scale supply-chain manufacturing for both efficiency and BOM costs, Krconn Technology Co., Ltd. has pioneered a next-generation core connectivity component: an integrated stamped-and-drawn precision charging PIN. This product has now officially entered mass production (volume production). The charging contact assembly innovatively employs a cutting-edge precision continuous-mold stamping and drawing process, successfully replacing the traditional MIM (metal injection molding) technique across the board. While achieving exponential growth in single‑mold production efficiency, it also slashes the underlying material cost by half and introduces a dual‑layer gold (Au) and platinum (Pt/white platinum) composite plating that sets a new industry benchmark. This is a core interconnect component designed for the next generation of skin-friendly smart hardware, boasting remarkable technological disruption and significant commercial value.

CPH01-04120101-01 Mixed-Insert Copper Post Clamp

In the context of increasingly compact internal spaces and ever-more-complex stacking architectures in smart wearables, precision modular medical components, and miniature consumer electronics, traditional unidirectional docking connectors often constrain the design flexibility of system engineers. To address this challenge, Krconn Technology Co., Ltd. has innovatively introduced a groundbreaking, ultra‑miniature, high‑reliability contact— the hybrid copper‑pillar clamp (model: CPH01-04120101-01). This product has now officially entered mass production. As a precision clamping connector specifically designed to mate with Φ0.50mm charging copper pillars, it achieves seamless multi‑axis insertion and removal compatibility within an extremely compact footprint (1.90mm wide × 1.60mm high), while delivering flagship‑level solder‑bonding retention strength. The product is crafted from high‑strength, highly resilient SUS stainless steel, with finely engineered localized gold (Au) plating layers applied to both the contact and soldering areas, providing intelligent hardware with a cutting‑edge power and signal interconnect solution that offers exceptional flexibility, superior reliability, and low impedance.

KRCONN Precision Charging Spring Contact, Reverse-Insert Assembly Type

As smart wearables and miniature consumer electronics evolve toward extreme thinness and high‑frequency, fast charging, traditional contact components commonly face challenges such as large space occupation, dust accumulation, and elastic fatigue after prolonged use. To address these issues, Krconn Technology Co., Ltd. (KRCONN), leveraging its deep expertise in precision mold R&D and interconnect technologies, has officially launched a new generation of reverse‑insertion, assembly‑type precision charging spring contacts (model: EPR348-03A50-01) (see the technical data diagram above). This product has now entered full‑scale mass production. As a highly reliable miniature charging and power‑transfer contact assembly, it ingeniously integrates a reverse‑insertion assembly structure with a four‑fold mechanical protection design within a compact footprint—body length 8.24 mm + tail width 5.12 mm, overall height 3.48 mm. The spring contacts are crafted from industrial‑grade, high‑elasticity phosphor bronze, with premium thick gold plating on the contact areas, delivering a low‑impedance, ultra‑long‑life, superior electrical interconnection solution for TWS Bluetooth earphone charging cases, smartwatches, and various portable smart devices.

KRCONN has successfully developed an IPX8‑rated waterproof Type‑C female connector.

Krconn has proudly launched its brand-new flagship IPX8‑rated waterproof Type‑C connector (model: TWR38‑18121605‑G5). Now fully in mass production, this connector is a highly integrated interconnect solution specifically designed for smart wearables, high‑end handheld devices, and demanding outdoor environments involving water exposure. The key breakthrough of this product lies in its attainment of the stringent IPX8‑level advanced protection standard—withstanding continuous immersion at a depth of 1.5 meters for 30 minutes without any leakage. Within an ultra‑compact, miniaturized form factor (total length just 7.10 mm, with a 2.40 mm‑thick receptacle), it ingeniously integrates a three‑layer shell laser welding process and cutting‑edge LIM liquid injection molding sealing technology. Additionally, it employs a premium SUS316L stainless steel inner housing, which not only delivers exceptional waterproofing, dustproofing, and EMI electromagnetic interference resistance but also boasts unparalleled corrosion‑resistant board‑mount strength.
