Abstract
Abstract A connection socket for a submersible electric motor includes a connection box of the motor provided with two plates, one of which holds connection pins. The other plate is arranged to divide the connection box into two sealed rooms to prevent liquid coming into the box along the electrical cable from going further into the motor.
