Product Description
The DC Male Power Plug to 2-Pin Screw Terminal Block is a premium, solderless adapter engineered to convert open power wires into a secure, standard DC barrel connection. This adapter features a universal 5.5mm outer diameter and 2.1mm inner pin male barrel plug on one side, cleanly integrated with a heavy-duty 2-pin screw terminal block on the other.
Designed to save time and eliminate wiring errors on your workbench, this adapter completely removes the need for hand-soldering, crimping tools, or messy electrical tape. Simply insert your stripped, bare wire leads directly into the terminal slots and tighten the screws down for an unyielding physical and electrical bond. It is an indispensable component for quick prototyping, building custom power supplies, wiring 12V LED strips, and installing CCTV security cameras.
⚠️ Polarity Safety Reminder: Always align your wiring with the heavy-duty polarity indicators molded clearly onto the plastic casing of the terminal block. The terminals are explicitly marked with a positive (+) symbol for your positive lead and a negative (–) symbol for your ground or negative lead. Reversing these connections can permanently destroy sensitive microcontrollers or circuit chips.
