BUCIER USB 2.0 A Female to 4-Pin Screw Terminal Adapter Green 2-Pack

USB 2.0 A Female to Screw Terminal Adapter

This adapter converts a standard USB Type A port into a 4-pin screw terminal block, allowing direct wire connections without soldering. It is intended for DIY enthusiasts, repair technicians, and hobbyists who need to extend or repair USB cables for devices such as keyboards, mice, printers, and cameras. The green terminal housing provides clear pin identification for V+, D+, D-, and ground connections.

Bundled Screwdriver and Dual-Pack Convenience

The package includes two adapters and a small screwdriver, so installation can begin immediately without sourcing tools separately. Having a spare unit on hand simplifies projects that require multiple connection points or provides a backup for future repairs. The solderless design means wires are secured by tightening the terminal screws, reducing the risk of cold joints and making field adjustments straightforward.

USB 2.0 Signal and Power Limitations

The adapter passes USB 2.0 signalling and power lines through the screw terminals, so cable length and wire gauge directly affect signal integrity and voltage drop. It does not incorporate active signal conditioning, so long runs or thin conductors may cause enumeration failures or reduced charging current. The nickel-plated contacts resist oxidation, but the terminal block itself is not rated for high-vibration environments without additional strain relief.
