This DC Inline Socket is a high-quality female power connector designed for cable-end installation, providing a secure and reliable docking point for standard DC power adapters. Featuring a 2.5mm center pin, it is engineered for higher-current applications and is commonly used in industrial equipment, laptop power supplies, and custom high-wattage electronic builds.
2.5mm x 5.5mm Specification: Designed with a 2.5mm internal pin to accommodate larger power plugs, ensuring a tight mechanical fit and consistent electrical contact for high-draw devices.
Integrated Flexible Strain Relief: Features a molded-rubber boot at the cable entry point to prevent wire fatigue and internal shorts caused by frequent bending or pulling.
Ergonomic Hexagonal Body: The textured, hexagonal housing provides a superior grip for easy plugging and unplugging, even in tight spaces or when wearing gloves.
Durable Solder Terminals: Internal metal terminals are designed for high-conductivity soldering, supporting heavy-gauge wire for maximum power efficiency.
Impact-Resistant Construction: Housed in a robust, matte-black polymer shell that resists physical impact and common workplace chemicals.
Internal Pin Diameter: 2.5mm.
Outer Socket Diameter: 5.5mm.
Connection Type: Female Inline Socket.
Termination Method: Internal Solder Lugs.
Housing Material: Heavy-Duty ABS/PVC with Nickel-Plated Contact.
High-Power Electronics: The standard interface for powering large LED arrays, 3D printers, and industrial networking hardware.
Laptop Repair & Extensions: Used to create custom power extension cables for laptops and notebook computers that utilize 2.5mm center pins.
Portable Battery Packs: Ideal for adding a power-out port to custom high-capacity battery enclosures like those used in robotics or field photography.
DIY Power Supplies: A reliable choice for building custom benchtop power supplies with interchangeable lead sets.
Will a 2.1mm plug fit into this 2.5mm socket? A 2.1mm plug may physically enter the 5.5mm opening, but it will not make a secure electrical connection with the 2.5mm center pin, likely resulting in intermittent power. Always match your plug and socket sizes exactly.
How do I wire this correctly? The center pin is typically wired as Positive (+) and the outer barrel sleeve as Negative (-). However, you should always check the polarity requirements of your specific device and use a multimeter to verify your solder joints.
Is it difficult to assemble? Assembly requires basic soldering skills. The outer shell unscrews to reveal the terminals; once soldered, the shell is screwed back on to encapsulate and protect the connection.
