A punchdown connection secures telecom wires by pressing them into a V-shaped metal slot that slices through the insulation and grips the bare copper. Technicians use a specialized spring-loaded impact tool to seat the wire and trim the excess in one motion. This method provides a gas-tight, reliable electrical contact without requiring stripping or soldering.
