Seal for cable splice closure

摘要

A seal for use in an optical closure is formed in the general shape of a truncated cone. The seal has an aperture which extends completely through the conical shape portion of the seal and which terminates within a plug located at the larger end of the seal. A sinusoidal shaped slit is formed completely through the seal from the small end of the seal to a small distance away from the large end of the seal. The seal is placed within an angled section of a port within an optical closure and an end cap is screwed into the port thereby forcing the seal further into the angled section. The seal can be used for both sealing ports which receive optical cables and ports which do not receive any cables. For the ports that do receive an optical cable, the plug is removed from the seal and the slit is extended all he way to the rear of the seal. When the optical cable is passed through the slit into the aperture of the seal, portions of the seal on either side of the slit become separated from each other.
