Abstract A sealed connector box for spliced electrical cables comprises a tubular central element interconnecting a pair of end elements to define a closed chamber within which electrical cable ends are inserted through small diameter end openings of the end elements and are spliced within the chamber. A conical sealing element is slid over each end of the electrical cable on both sides of a splice and each sealing element has an outer end which sealingly engages the inner face of the tubular central element. A ring has a peripheral surface supporting the inner face of the outer sealing end of each sealing element. The outer end sealing surface of each sealing element may comprise one or more corrugations which closely engage the inner face of the tubular central element. A bolt interconnects the tubular element to clamps positioned on each cable end between the supporting ring and end element so as to securely couple the tubular central element to the cable ends.
A sealed splice of electrical cables comprising a pair of end elements each having a small diameter end opening through which an electrical cable is inserted and a large diameter end opening, a tubular central element interconnecting the large diameter ends of said end elementS defining a closed chamber within which the electrical cable ends are spliced, a conical sealing element slid over each end of the electrical cable on each side of said splice, said sealing elements each having an outer end sealingly engaging the inner face of said tubular central element, and a ring supporting the inner face of the outer sealing end of each sealing element.
