  • Power plug system for submersible pump system
    Patent number: 8029317
    Abstract: A power plug system for use with a submersible pump. One embodiment comprises a male plug end, a female plug end, and a plurality of seals. The male plug end comprises a housing and a conductive sleeve. The housing receives an electrically conductive cable and conducts an electric current from the cable to the conductive sleeve. The female plug end comprises a housing, a conductive pin, and a female plug sleeve. The conductive sleeve is radially sealable within the female plug end through a plug end seal of the plurality of seals. The conductive sleeve and the conductive pin are conductively connectable. The female plug sleeve is radially sealable within a complementary plug end through a female plug sleeve seal of the plurality of seals. The conductive pin conductively connects to a conductive lead of the complementary plug end with insertion of the female plug sleeve therein.
