Ideal replacement connector

These straight blade plugs serve as direct replacements for worn or damaged DC power connectors on standard devices. The 4.0 mm by 1.7 mm barrel size fits many common power supply jacks. A pack of six ensures spares are on hand for multiple repairs or future maintenance needs.

Compact low-profile design

Each plug measures approximately 45 mm in total length and weighs only 13 g for the complete set. The lightweight construction adds minimal bulk to cable assemblies. No active cooling or power regulation is involved, so thermal output and noise are non-existent during normal operation.

Six-piece bulk pack

The package contains six identical male barrel connectors in a black and silver-tone finish. This quantity supports batch repairs or provides reserves for technicians and hobbyists. No additional tools, software or adapters are included with the plugs.

Questions about this item

How do I solder the 4.0mm x 1.7mm barrel plug and which terminal is positive?

The centre pin is positive on standard DC barrel connectors; tin the stripped wire, insert it through the strain-relief sleeve, solder to the pin and sleeve tabs, then crimp the cable clamp before sliding the housing on.

Will the gold-plated contacts need cleaning or replacement over time?

The plugs use silver-tone contacts; wipe with isopropyl alcohol if oxidation appears, and replace a plug if the spring tension drops or the housing cracks — no scheduled interval is required.

At what current does the 45mm plug body become the limiting factor?

The compact 45mm housing and 13g weight indicate a low-current design; sustained loads above roughly 2 A will cause noticeable heating at the solder joints first.
