Abstract
Connectors for terminating and splicing high voltage power cables comprise a metallic tubular sleeve having an open end for receiving an electrical conductor and a closed end. The inner wall of the sleeve is pretinned. The sleeve can be provided with a slug of solder proximate to the closed end. A connection is made by inserting the conductor into the sleeve, heating the solder, and as the solder melts, relatively moving the connector and the conductor toward each other. The connector can be provided with an insert to accommoduate conductors that are non-circular in cross-section. The connector can be provided with means for pressuring the slug of solder toward the open end of the sleeve at the temperature at which the slug of solder melts. With this connector, no relative movement between the conductor and the connector is required. Merely by melting the solder, the means for pressuring causes the solder to extrude around the conductor.
