ABSTRACT:
An electrical cable connector for connecting an electrical cable to an electric motor, especially in an oil well. The electrical cable connector includes a hollow cylindrical housing receiving a portion of the electrical cable therein and a sealing assembly for sealing the space between the cable and the housing to prevent the corrosive material in the oil well from eroding the electrical connection. The sealing assembly includes a disk rigidly coupled to the housing and a movable disk axially biased towards the other disk. A sealing plug is positioned between the two disks and comprises a substantially uncured flowable, incompressible seal material sandwiched between a pair of cured rubber sealing disks. The movable disk asserts pressure on the sealing plug so that the flowable material will flow into any otherwise empty spaces between the sealing disks and the cable and between the sealing disks and the housing.
