Cage clamps (also known as spring clamps, cage terminal blocks, or push-in terminals) are a type of electrical connector used to secure wires in place without the need for screws. They’re especially popular in industrial control panels, building wiring, and other applications requiring reliable and vibration-resistant connections.
Key Features:
-
Spring-loaded mechanism: Uses a spring to press the wire against a conductive surface, ensuring a strong electrical connection.
-
Tool-free installation: Many types allow wires to be inserted without tools (though removal might require a small flathead screwdriver or pin).
-
Vibration-resistant: The spring mechanism keeps wires tightly in place, reducing the chance of loosening due to vibration.
-
Suitable for solid or stranded wires: Compatible with various wire types (though stranded wires may need ferrules).
Advantages:
-
Quick and easy to install or change wiring.
-
Safer and more consistent than screw terminals (which can loosen over time).
-
Compact design saves space in terminal blocks and panels.
-
Ideal for DIN rail terminal blocks (common in automation and electrical control).
Common Uses:
-
Industrial automation panels.
-
Building electrical systems.
-
Control cabinets.
-
Lighting installations.
