Screwless PCB terminal blocks provide a designer with a versatile wire to board connection method.

Wires are connected to the terminal block by using a push actuator, a cage clamp then opens up once the actuator has been pushed, and the wire can then be inserted, once the actuator has been let go the cage clamp terminal holds the wire in place.

Screwless terminal blocks allow for assemblies to be set up quickly and easily, without having to screw the wires into place. This also shortens the time it takes to carry out maintenance, such as replacing old or faulty wires.

Screwless terminal blocks can be found in pitch sizes 2.5mm up to 7.62mm pitch.

Guozhi Electronics also manufacture screwless pluggable terminal blocks for applications where the connection will need to be broken but the user does not necessarily want to remove the wires.

Screwless terminal blocks automatically grip the stripped ends of inserted 26 – 18 AWG wires, allowing for easy, temporary connections to your PCB, and units can be combined to make longer blocks.
