【Product Overview】DC-002 Horizontal PCB Mount Small Aperture DC Power Jack
DC-002 is a classic solution engineered for miniaturized, portable electronic products PCB board-mounted miniature DC power jack (female connector). This product adopts a right-angle horizontal PCB mount structure with a standard 3-pin solder terminal design, primarily suited for 3.5×1.1mm and 3.5×1.35mm connecting small-specification DC power adapter male plugs.
As electronic products trend toward thinner and more compact designs, DC-002, with its small footprint and excellent soldering stability, is widely used in portable digital devices, small household appliances, medical testing instruments, and smart home terminals. The internal contacts are crafted from high-elasticity copper alloy, ensuring extremely low contact resistance and superior electrical conductivity through repeated plugging cycles and long-term operation.
---【Key B2B Selling Points and Process Advantages】
1. Compact miniature structure, saving PCB space
Compared to traditional 5.5mm large-aperture jacks, DC-002 features a smaller overall size, significantly reducing the PCB footprint required. It is an ideal power interface solution for space-constrained, slim-profile, and portable electronic devices.
2. High-quality copper alloy contacts, low impedance and durable for repeated plugging
The internal conductive contacts are made of high-precision copper alloy, with a nickel/silver-plated anti-oxidation surface treatment. The internal spring plate is designed with moderate clamping force, ensuring smooth insertion and extraction without loosening. After more than 5,000 rigorous mechanical insertion/withdrawal life tests, it maintains excellent electrical conductivity.
3. Standard 3-pin configuration, easy to solder and compatible with wave soldering
It adopts a standard 3-Pin solder pin structure (including power positive and negative poles and an auto-switching normally closed contact). The pins are easy to solder and resistant to soldering heat. It is fully compatible with automatic wave soldering and manual soldering processes on factory production lines, effectively reducing the cold solder joint rate.
4. High-temperature-resistant flame-retardant housing, ensuring electrical safety
The socket's main protective housing uses high-temperature resistant engineering plastics (such as PBT/PA66), offering excellent insulation performance and impact strength. It resists deformation during reflow soldering or under high-load heat generation, ensuring the safety and stability of the equipment's power input.
