Scotchlok butt connectors employ a specially designed, wire insulation displacement contact to make a reliable electrical connection to each wire. A “livespring” 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 required. Scotchlok butt connectors include a factory-installed sealant to protect against corrosion and seal out moisture.
The small size of the UY connector reduces the splicing bundle O.D. to a minimum. The connector’s two ports accept two solid copper conductors. The connector is filled with a sealant to provide moisture resistance.
