Abstract
A split shell connector accessory for electrical cables comprising a pair of shell halves having a passage therethrough for receiving and holding a cable. An adapter is mounted at each end of the passage. One shell half has an elastomeric sealing member extending continuously along each side of the cable holding passage and the other shell half has a complementary groove. Each adapter has an O-ring which fits into complementary grooves in the adapters. The O-rings extend in a plane transverse to the plane of the elastomeric sealing members. When the shell halves are tightened together, the adjacent portions of the elastomeric members and O-rings are compressed into engagement with each other to form a complete environmental seal. Complementarily engaging ridges and grooves on the shell halves and adapters provide complete RFI/EMI (radio frequency interference/electromagnetic interference) shielding.
