Import Ac Power Connectors — Buy in Bulk from Supplier in China

These AC power connectors are 2-pin conversion devices designed to bridge flat-pin and round-pin configurations, enabling interoperability between regional plug standards in portable and fixed electrical equipment. The supplier, Changzhou Yunyu Electronic Co., Ltd, specifies compatibility with international standards and a voltage rating suitable for domestic and light industrial applications. The physical construction centres on a robust housing with pin interfaces engineered for repeated insertion cycles, with safety mechanisms intended to mitigate overcurrent and short-circuit fault conditions.

The contact material and plating specification directly determines conductivity, contact resistance stability, and corrosion resistance in humid or saline environments. Standard industry practice for this connector category employs brass or phosphor bronze substrates with nickel underplating and tin or silver top plating, though the listing does not confirm the exact metallurgy. Insulation materials typically range from polyamide 66 to polycarbonate, selected for glow-wire test performance and tracking resistance per IEC 60335-1 requirements for appliance connectors. The 2-pin format without earth conductor limits application to Class II (double-insulated) equipment or where supplementary earthing is provided through alternative means.

Primary buyers include appliance manufacturers seeking regional variant power entry modules, aftermarket accessory suppliers, and industrial equipment makers requiring interchangeable power connections for export products. The connectors serve consumer electronics, automotive aftermarket (battery chargers, portable tools), and light commercial equipment where frequent plug standard changes occur. Importers should confirm with Changzhou Yunyu the specific pin dimensions (pin diameter, length, and spacing for round pins; blade width, thickness, and configuration for flat pins), as dimensional non-compliance causes insertion force problems and contact overheating in target markets.

Changzhou Yunyu Electronic Co., Ltd is located in Sanqin Village, Hutang Town, Changzhou City, Jiangsu Province, a region with established electronics manufacturing infrastructure and strong supplier networks serving the Yangtze River Delta industrial corridor. The company's 'harbor' trust tier and 'imported' supplier classification indicate platform listing without substantial verified transaction history or response performance, evidenced by a 0.00% response rate and no recorded average response hours. This profile pattern is common for smaller manufacturers or trading offices in the Changzhou connector and electronics accessory cluster, where many firms compete on OEM and ODM service provision.

The supplier's product focus on AC power connectors aligns with Changzhou's historical strength in electrical components and electromechanical manufacturing, though the listing provides no factory size, annual turnover, quality system certification, or named OEM client information. The rural-village address format suggests a manufacturing or warehouse location rather than central business district offices, which can indicate direct production capability but also warrants verification of actual facilities. Buyers should independently confirm Changzhou Yunyu's manufacturing scope, whether it produces connector inserts and housings in-house or sources from sub-suppliers, and what inspection and testing protocols are applied before shipment.
