【Product Overview】DC-004 Vertical PCB-Mount DC Power Jack

DC-004 is a high-performance PCB board-mounted vertical DC power jack (female). This product adopts a 90-degree vertical insertion pin design, primarily matching and and 5.5×2.5mm two industrial-grade standard DC power adapter male plugs.

Compared to horizontal jacks, the vertical layout of DC-004 better accommodates top or side vertical panel openings on specific devices. Internally, thickened arc-shaped high-elasticity contact blades paired with a thick center pin significantly increase the conductive contact area, effectively preventing power interruptions or poor contact when the interface is subjected to lateral pulling.

【Key B2B Selling Points and Process Advantages】

1. Vertical layout, adapted to specific panels and structural spaces

Adopting a 90-degree vertical insertion and removal structure, it is suitable for industrial and electronic terminals that require power input in the vertical direction of the PCB board. The vertical mounting distributes force evenly, enabling it to withstand greater vertical insertion and removal forces as well as lateral pulling.

2. Thickened arc spring plate and thick center pin ensure stable conductivity without false contact

The internal conductive contact plate is made of thickened high-elasticity copper alloy, with a finely nickel-plated surface for oxidation resistance and wear resistance. The V-shaped arc contact structure provides lasting and stable clamping force, effectively reducing contact resistance and temperature rise during current flow.

3. Standard 3-pin solder pins, smooth wave soldering through the furnace

The pin layout is reasonable and easy to tin, with excellent resistance to soldering heat. It is fully compatible with automated placement and traditional wave soldering processes, helping production lines reduce cold solder joint rates and improve factory pass rates.

4. High-insulation flame-retardant housing ensures long-term safe operation

The housing insulation components are made of high-temperature-resistant, impact-resistant industrial-grade engineering plastics (PBT/PA66), offering excellent electrical insulation and thermal stability, maintaining structural stability even under prolonged high-load power conditions.
