【Product Overview】DC-003A Horizontal PCB Mount DC Power Jack with Positioning Pins

DC-003A It is a model equipped withBase anti-error positioning pin (locating pin)High-reliability miniature PCB-mounted DC power jack (female connector)This product adopts a right-angle horizontal plug-in board structure, specifically designed for 3.5×1.1mm and 3.5×1.35mm Small DC power male connector design.

Unlike ordinary miniature sockets, the DC-003A features an additional positioning post structure on its plastic base. During PCB assembly, the positioning post can precisely snap into the pre-drilled holes on the circuit board, which not only enablesAssembly Poka-Yoke and Error-Proofing, it can also significantly enhance the socket's resistance to mechanical stress when subjected to lateral pulling, ensuring that solder joints do not crack or loosen.

【Key B2B Selling Points and Process Advantages】

1. Bottom Anti-Error Positioning Post Design for Improved Assembly and Anti-Wobble Performance

The base comes with precision positioning feet that automatically align with the PCB mounting holes during placement, effectively preventing skew and misalignment during manual insertion. During frequent plugging and unplugging, the positioning posts absorb most of the physical pulling force, protecting the soldering terminals from damage.

2. High-Clamping-Force Alloy Contacts for Low Temperature Rise and Spark-Free Conduction

High-elasticity copper alloy is selected for the conductive structural components, combined with fine nickel/silver plating coatings to significantly reduce contact resistance. The clamping force during insertion and withdrawal is uniform, effectively preventing electrical sparks caused by poor contact, and ensuring low temperature rise during prolonged high-current operation.

3. High-Temperature-Resistant Engineering Plastics for Easy Wave Soldering Process Compatibility

The housing insulation material uses high-grade, high-temperature-resistant PBT/PA66 engineering plastics, offering excellent mechanical strength and thermal stability. During factory wave soldering or manual high-heat soldering, the plastic body does not deform or collapse.

4. Compact Ultra-Small Footprint for Slimmer End Devices

While ensuring excellent mechanical strength, it maintains an extremely lightweight and compact size, greatly saving PCB layout space. It is an ideal power input solution for smart wearables, portable digital devices, and small household appliances.
