XH 3-Pin to Spade Terminal Wire Harness

Our product is an adapter wire harness featuring a standard XH series 3-pin connector on one end and a spade terminal on the other, designed specifically for power or signal conversion connections between different interface standards. It is widely used in consumer electronics, LED lighting equipment, small household appliances, power modules, power tools, and various electronic devices requiring board-to-wire or wire-to-wire conversion connections. The XH series terminal is one of the most widely used standardized connector families in the industry, featuring a standard 2.54mm pitch design with notable advantages such as a compact structure, convenient insertion/removal, and a secure connection. 
Its mating female socket is typically soldered directly onto a PCB, with an internal spring-clip structure that ensures stable engagement during insertion, resisting loosening caused by vibration or external disturbances — making it particularly well-suited for internal board-to-wire connections in electronic devices where connection reliability is critical.
The 3-pin design simultaneously accommodates the transmission of three power or signal lines, with common applications including combined transmission of positive/negative power lines plus a signal line, three-phase line transmission, or other parallel multi-channel signal transmission scenarios — offering broad application coverage that meets the actual wire needs of most electronic devices. The terminal body is precision-stamped from high-quality copper alloy and surface-treated with tin plating, offering excellent conductivity and oxidation resistance, with smooth insertion/removal and stable contact that maintains consistently low contact resistance over the long term, fully ensuring the efficiency of power transmission and the accuracy of signal transmission.
The other end of the harness transitions to a spade terminal, one of the most widely used quick-connect terminal formats in the industry, offering notable advantages such as simple insertion/removal operation, no need for additional tools, and broad application compatibility. It enables quick connection to the vast majority of corresponding switches, relays, fuse holders, motor terminal posts, and other components available on the market, with common specifications spanning 2.8mm, 4.8mm, 6.3mm, and other sizes, flexibly selectable according to the customer's actual device interface requirements. The wire section in the middle of the harness is manufactured using high-quality copper core conductors, with wire gauge selectable according to the customer's actual current-carrying requirements, wrapped in a wear-resistant, aging-resistant, and flame-retardant insulation sheath, fully ensuring the electrical safety and mechanical durability of the harness during long-term use and enabling it to withstand a variety of complex and changing usage environments. We support customization of overall harness length, wire color assignment, specific spade terminal specifications, and sheath material according to each customer's actual device interface standards, and provide rigorous factory quality inspections, including continuity testing, tensile strength testing, and insulation resistance testing, ensuring every harness meets relevant industry standards before shipment — providing customers with a stable, reliable, and highly adaptable customized adapter wire harness solution, serving industries such as consumer electronics, lighting equipment, small appliance manufacturing, and power tools.
