Abstract
A submersible motor comprising a first housing including a motor and a second housing enclosing electrical connections between the motor and a jacketed electrical cord to the second housing. The first housing has a cavity therein in the periphery thereof. A body of compressible resilient elastomeric material is positioned in the cavity and has an exterior configuration and dimensions which conform generally with the configuration and dimensions of the cavity. The body has a plurality of generally axial passages therein through which the magnet wires from the motor extend. The wires have a diameter so that they can be readily inserted through the passages in the body. The second housing has an annular wall extending axially through the open end of the cavity in the first housing and operable, when the second housing is in mounted position on the first housing, to compress the body radially into tight conformity with the wires from the motor.
