Female DC Power Adapter DC Barrel Jack Female to 2-Pin Terminal Block Adapter

Overview

The Female DC Power Adapter (5.5mm × 2.1mm Barrel Jack to 2-Pin Terminal Block) is a rugged, solderless power transition connector designed to make power delivery fast, clean, and reliable. Featuring a standard 5.5mm outer diameter and 2.1mm center pin female socket on one side, it terminates directly into heavy-duty screw terminals spaced 5mm apart on the other. Clearly embossed with positive (+) and negative (-) polarity indicators, this adapter completely eliminates the need for soldering or wire splicing when connecting wall adapters, batteries, and bench power supplies to prototyping boards, LED strips, and CCTV installations.

Key Features

• No Soldering Required: Secure screw-down terminal block accepts stripped solid or stranded wire in seconds using a standard precision screwdriver.
• Universal 5.5mm × 2.1mm Sizing: Fits standard 5V, 9V, 12V, and 24V power adapter barrel plugs used across electronics and security gear.
• Embossed Polarity Labels: Highly visible (+) and (-) indicators prevent costly reverse-polarity accidents on delicate circuitry.
• High Current Throughput: Heavy-gauge internal copper contacts safely handle continuous DC currents up to 5A.
• Industrial Grade Housing: Tough, flame-retardant molded PVC casing resists impact and strain in demanding workshop environments.
• Reusable & Reconfigurable: Quickly unscrew to swap wires, test power topologies, or reconfigure field prototypes without cutting cords.
