Product Description
A DC 2.1mm male power plug with a screw terminal is how you re-terminate a 12V cable without solder. It fits the standard 5.5mm x 2.1mm DC power sockets used on CCTV cameras, DVR power supplies and low-voltage LED fittings.
What it's for
If a power lead has been cut short, damaged, or needs building from scratch, this plug lets you connect the positive and negative conductors with a screwdriver rather than a soldering iron. That's useful when you're working inside a camera housing, junction box, or power distribution enclosure where there's no room (or time) for a hot iron.
Before you buy — check this
- Socket size: confirm the device you're powering uses a 5.5mm x 2.1mm DC socket — this plug won't fit other diameters.
- Voltage: it's designed for 12V DC systems, matching typical CCTV camera and DVR power supplies.
- Termination method: screw terminal, not solder — no soldering iron or heat-shrink needed.
Typical jobs
- Re-terminating a CCTV camera power lead after cutting to length
- Wiring a DVR or NVR power supply
- Building custom runs for 12V LED or low-voltage lighting
- Field installation where soldering isn't practical
It's a straightforward, no-soldering way to get a secure DC connection on site.
