3M Scotchlok IDC Butt Connectors employ a specially designed, wire insulation displacement contact to make a reliable electrical connection to each wire. A “live-spring†joint is made by driving the wire down into the “U†contact connector. This simple process displaces the insulation and grasps all conductors with a firm, resilient pressure, all in one motion - no stripping of wire insulation is required.
The 3Mâ„¢ Scotchlokâ„¢ Butt Connector UR2 accepts two or three solid copper conductors for butt splicing. The connectors include a factory-installed sealant to protect against corrosion and seal out moisture.
