Connector adapter for DC projects

This 5.5 mm by 1.7 mm male to 5.5 mm by 2.1 mm female adapter bridges mismatched barrel connectors on power supplies and devices. It suits hobbyists repairing cables or installing CCTV cameras where plug sizes differ. The compact body fits tight enclosures without adding bulk. Buyers needing a different pin diameter or a locking barrel will not find it here.

Passive connection with no active cooling

The adapter contains no electronics, so it generates no heat and draws no power beyond the attached supply. Operation is completely silent because there are no moving parts. Voltage and current limits depend entirely on the source and load you connect. It does not regulate, convert or protect against overloads.

Yellow barrel body measuring 41 mm by 12.5 mm

The moulded housing is 41 mm long and 12.5 mm in diameter with a yellow finish for quick visual identification. A snug friction fit holds the male tip in a 5.5 mm by 2.1 mm socket while the female end accepts a 5.5 mm by 1.7 mm plug. The straight profile keeps cable routing simple in rack or wall-mount installs.

Questions about this item

How do I fit the 5.5 mm × 1.7 mm male plug into my device and avoid the loose-connection mistake?

Align the centre pin and outer barrel, then push straight in until the 12.5 mm barrel seats fully; the common error is stopping at the first click, which leaves a 1 mm gap and intermittent power.

What wear should I watch for on the 5.5 mm × 2.1 mm female jack over time?

The spring contacts inside the 2.1 mm bore can lose tension after repeated insertions; if the plug wobbles or power cuts when the cable moves, replace the adapter.

At what current does the 41 mm long adapter body become the limiting factor during continuous use?

The compact 41 mm × 12.5 mm housing has no heatsinking, so sustained loads above roughly 2 A will make the body noticeably warm and increase voltage drop.
