Abstract
An electrical submersible well pump motor has metal-to-metal sealing for the power cable electrical connection. A conductor passage in the motor head has a conical seat. A motor contact member electrically connected with the motor is located in the conductor passage below the seat. A metal tube has a lower portion that inserts into an upper portion of the conductor passage. A metal sealing ferrule encircles the tube, and a compression nut deforms the ferrule into sealing engagement with the seat and the tube. An electrical conductor extending from the power cable protrudes downward from the tube and has a conductor contact member on a lower end. The motor contact member and the conductor contact member stab into partial engagement with each other, defining a gap between terminal surfaces of the contact members that can close up during operation due to thermal growth.
