Circuit Board Barrel-Style DC Connectors
Install these connectors directly onto circuit boards to carry DC power from a power supply to your device. The industry standard barrel-style ends are often found on power supplies for laptops, wireless routers, and other common electronics. Push the contacts through holes in your circuit board and solder them in place.
Push-in connectors are quicker to connect and disconnect than screw-together connectors.
Screw-together connectors are less likely to disconnect from vibration or getting yanked out than push-in connectors. This makes them good for preventing power loss. However, they take longer to connect and disconnect.
