Crushed Seal Arrangement for Motor Electrical Connection of Submersible Well Pump

A submersible well pump assembly, comprising:

• a pump;
• an electrical motor operatively connected with the pump for driving the pump;
• an electrical receptacle on the motor, having a base with a central bore containing a plurality of motor electrical terminals therein;
• an annular groove in the base encircling the central bore, the groove having inner and outer cylindrical walls relative to an axis of the bore and a closed bottom;
• a motor lead extending to the motor for supplying power to the motor;
• an electrical connector on an end of the motor lead that mates with the receptacle, the electrical connector having a housing containing a plurality of electrical conductors, each having a motor lead terminal that electrically connects with one of the motor electrical terminals in the receptacle;
• a rim on the housing that inserts into the groove, the rim having inner and outer wall surfaces that engage the outer and inner walls, respectively of the groove;
• at least one of a forward edge of the rim and the bottom of the groove being conical, defining an annular void within the groove that is triangular in cross section when the rim is fully inserted into the groove;
• a seal ring located in the void of the groove;
• and wherein
• the forward edge of the rim engages and deforms the seal ring into sealing engagement between the groove and the rim when the rim is inserted into the groove.

A submersible well pump assembly, comprising:

• a pump;
• an electrical motor operatively connected with the pump for driving the pump;
• an electrical receptacle on the motor, having a flat base with a central bore containing a plurality of motor electrical terminals therein;
• a circular annular groove in the base encircling the central bore, the groove having concentric cylindrical inner and outer walls terminating in a flat bottom;
• a seal ring located in the groove;
• a motor lead extending to the motor for supplying power to the motor;
• an electrical connector on an end of the motor lead that mates with the receptacle, the electrical connector having a housing containing a plurality of electrical conductors, each having a motor lead terminal that electrically connects with one of the motor electrical terminals in the receptacle;
• a cylindrical rim on a forward end of the housing that inserts into the groove, the rim having a forward edge that is conical and which deforms the seal ring against the bottom of the groove;
• and
• the housing having a shoulder that abuts the base and positions the forward edge of the rim from the bottom of the groove when the rim is Bally inserted into the groove.
