ABSTRACT:
A cylindrical metallic sleeve has opposite end portions and a cylindrical body portion with a longitudinal passageway for receiving the end portions of a conducting cable in overlapping relation. A shaped annular portion is formed adjacent the sleeve end portions and includes an inner, outwardly flared cylindrical surface and an outer cylindrical surface that intersect in a rounded end portion. The outer cylindrical surface is planar and positioned substantially parallel to the sleeve cylindrical body portion so that the insulation surrounding the cables adjacent the sleeve end portions is not abraded upon flexing the spliced cable. The flared inner surface is removed from contact with the overlapping cable end portions in the sleeve to permit flexing of the cable end portions therein without abrading the cables. The sleeve body is crimped into frictional engagement with the overlapped cable end portions. The exposed portions of the spliced conductor cable are enclosed with insulating materials to provide a flexible, insulated cable splice that may be wound around a cable reel and/or guide sheaves.
