A connector for connecting electrical power to a well pump motor has cable and motor connector portions that mate with each other in a connected position. The connector portions have insulating members, each of which has a number of passages and an end face. Electrical contact members are mounted in each of the passages. The ones in the cable connector portion protrude past the end face of the insulating member. An end face seal surrounds each of the protruding contact members and is deformed by engagement of the end face of the motor insulating member when the cable and motor connector portions are in the connected position.

We claim: 1. An apparatus for connecting electrical power to a well pump motor; first and second connector portions that mate with each other in a connected position, one of the connector portions adapted to be connected to a power cable and the other to a well pump motor; the first and second connector portions having first and second insulating members, respectively, each of the insulating members having a plurality of passages and an end face; a first electrical contact member mounted in each of the passages of and protruding past the end face of the first insulating member, the first electrical contact member having a circular cross-sectional configuration; a second electrical contact member mounted and recessed within each of the passages of the second insulating member; a plurality of end face seals, each end face seal having a circular inner diameter surrounding and sealingly receiving a single one of the first electrical contact members and deformed by engagement of the end face of the second insulating member when the first and second connector portions are in the connected position; a plurality of sleeves of electrical conductive material, each of the sleeves enclosing a protruding portion of one of the first electrical contact members, each of the sleeves protruding past the end face of the first insulating member to a distance less than the protruding portion of each of the first electrical contact members; and a plurality of elastomeric sleeve seals, each of the sleeve seals extending around one of the cable contact members, in contact with an end of one of the sleeves and located within one of the passages in the second connector portion when the connector portions are in the connected position. 2. The apparatus of claim 1, wherein each of the end face seals has an outer diameter that is free of sealing engagement when the connector portions are in the connected position. 3. The apparatus of claim 1, wherein each of the sleeve seals is in contact with an end of one of the second electrical contact members when the connector portions are in the connected position. 4. The apparatus of claim 1, wherein the end faces are spaced apart from each other when the connector portions are in the connected position. 5. An apparatus for supplying electrical power to a well pump motor, comprising: a cable end housing for connection to a power cable; a cable insulating member of insulating material disposed within the housing and having at least one passage therethrough; an electrical conducting cable contact member mounted in the passage of the cable insulating member and adapted to be joined to a conductor in the cable, the cable contact member protruding past an end face of the cable insulating member; a motor insulating member of insulating material adapted to be mounted in a receptacle of an electrical motor and having at least one passages therethrough, the motor insulating member having an end face; an electrical conducting motor contact member in the passage of the motor insulating member that is engaged by the cable contact member when the cable end housing and the receptacle are in a connected position; an end face seal surrounding the cable contact member and sealingly deformed between the end faces of the cable insulating member and the motor insulating member when cable end housing and the receptacle are in the connected position; a sleeve of electrical conductive material enclosing a protruding portion of the cable contact member, the sleeve being in electrical contact with the cable contact member, protruding past the end face of the cable insulating member and having a rim at a distance from the end face of the cable insulating member less than an end of the cable contact member; and an elastomeric sleeve seal extending around the cable contact member and in contact with the rim of the sleeve. 6. The apparatus according to claim 5, wherein the end faces are spaced apart from each other when the cable end housing and the receptacle are in the connected position. 7. The apparatus of claim 5, wherein the end face seal has an inner diameter that seals to an outer diameter of the cable contact member. 8. The apparatus of claim 5, wherein the end face seal has an outer diameter that is free of sealing engagement. 9. The apparatus of claim 5, wherein the sleeve seal extends into the passage of the motor insulating member and is contacted by an end of the motor contact member and forced against the rim of the sleeve. 10. The apparatus of claim 5, wherein the sleeve seal has an outer diameter smaller than a diameter of the passage in the motor insulating member. 11. An apparatus for supplying power to a well pump motor, comprising: a cable end housing for connection to a power cable; a cable insulating member of rigid insulating material disposed within the housing and having a plurality of passages therethrough; a plurality of electrical conducting cable contact members, each of the cable contact members being mounted in one of the passages of the cable insulating member and adapted to be joined to a conductor in the cable, each of the cable contact members protruding past an end face of the cable insulating member; a plurality of annular elastomeric end face seals, each of the end face seals extending around one of the cable contact members and in contact with the end face of the cable insulating member; and a receptacle for connection to a well pump; a motor insulating member of rigid insulating material mounted in the receptacle and having a plurality of passages therethrough; motor contact member in each of the passages of the motor insulating member and positioned to be engaged by one of the cable contact members when the housing and the receptacle arc in a connected position; the motor insulating member having an end that contacts and deforms the end face seals against the end of the cable insulating member when the housing and the receptacle are in the connected position; a plurality of sleeves of electrical conductive material, each of the sleeves enclosing a protruding portion of one of the cable contact members, each of the sleeves having a portion located within one of the passages of the cable insulating member and another portion protruding past the end of the cable insulating member, each of the sleeves having a rim located a distance from the end face of the cable insulating member less than less than an end of each of the cable contact members; and a plurality of elastomeric sleeve seals, each of the sleeve seals extending around one of the cable contact members and in contact with the rim of one of the sleeves when the housing and the receptacle are in the connected position. 12. The apparatus of claim 11, wherein each of the sleeve seals is contacted and deformed against the rim of one the sleeves by an end of one of the motor contact members when the housing and the receptacle are in the connected position. 13. The apparatus of claim 11, wherein each of the sleeve seals has an outer diameter less than an outer diameter of each of the passages in the motor insulating member. 14. The apparatus according to claim 11, wherein the end faces are spaced apart from each other when the housing and the receptacle are in the connected position. 15. The apparatus of claim 11, wherein each of the end face seals has an inner diameter that seals to an outer diameter of the cable contact member. 16. The apparatus of claim 11, wherein each of the end face seals has an outer diameter that is free of sealing engagement.
