Import 3.1 Double Layer Connector — Buy in wholesale FOB from Supplier in Hong Kong

The 3.1 Double Layer Connector from XKB Industrial Precision Co., Limited combines a USB Type-C 14-pin receptacle with a USB 2.0 female seal interface in a single stacked assembly. The unit measures 13.6 x 13.1 mm in profile, a compact form factor suited to space-constrained PCB layouts in automotive displays and fast-charging equipment. The Type-C channel is rated for 8.0A current carrying capacity, while the USB 2.0 channel handles 5.0A, enabling simultaneous high-current power delivery and legacy data support. This two-in-one configuration reduces connector count and board area compared to discrete implementations.

The connector employs a double-sided insert design with an optional single-sided insert variant, providing flexibility for different assembly processes and user-access orientations. Contact resistance is specified at 20 milliohms or less, with insulation resistance of 100 megohms or more at DC 250V, typical parameters for connectors in this current class. The resistance to soldering heat is rated at 250 degrees C plus or minus 5 degrees C, standard for reflow soldering compatibility. Housing material is not explicitly stated but is typically a high-temperature thermoplastic, LCP or PBT, for this connector category. The 10,000 cycle plug life indicates a robust design for consumer electronics and automotive applications with moderate insertion frequency.

Target buyers include manufacturers of automotive infotainment systems, portable charger assemblies, and network communication equipment where vertical space is limited and dual-protocol connectivity is required. The combined data and power capability suits quick-charge applications where Type-C PD negotiation coexists with USB 2.0 legacy device support. XKB positions this connector as a space-saving alternative to separate Type-C and USB 2.0 ports. Buyers should confirm whether XKB provides 3D step models, recommended PCB pad layouts, and tape-and-reel packaging specifications for automated assembly. Exact MOQ, lead time, and pricing are not provided and require direct supplier confirmation.

XKB Industrial Precision Co., Limited operates from Liz Center, 12th Floor, A1 Block, Hong Kong 999077. The company holds a harbor trust tier, indicating basic platform verification. The response rate shows 0.00% with zero average response hours, suggesting that engagement metrics are not yet established or the supplier does not route communications through the platform. Buyers should test direct contact channels early to gauge responsiveness and technical support capability before finalising design integration.

The supplier brands itself as XKB Connector (XKB) and markets this product for automotive display, car charger, and charger system applications. The listing emphasises combined Type-C and USB 2.0 functionality with focus on data rate and charging flexibility. No information is provided about factory location in mainland China, year of establishment, employee count, revenue, or major client relationships, and none should be invented. The Hong Kong address suggests a trading or design office, with manufacturing likely in Guangdong province, though this should be confirmed directly with XKB.
