FIELD: electric engineering.
SUBSTANCE: elastomeric seal is installed on the end side of the case in the holes made for each wire, pressed with a sleeve to fix the seal around the wire, connected to the case by a thread. The end of the seal is conical to ensure the tightness of the wire from the pressure direction, and the inner surface of the sleeve for fixing the seal around the wire mimics the configuration of the seal to ensure the tightness of the wire and compresses the seal. The angle of conical part of the seal is made in the range from 5 to 10 degrees, which ensures its uniform compression by the sleeve to fix the seal around the wire over the entire core area. The coupling is a metal case with a block inside of it, pressed with a sleeve to fix the block, connected to the body by a thread. In the case and the block, axisymmetric holes are made; cable wires pass through them.
EFFECT: pressure integrity improvement.
