Patent ID: 7854629

Claim:
A power plug system comprising an electrically conductive cable, a male plug end, a female plug end, and a plurality of seals, wherein: the male plug end comprises a housing and a conductive sleeve; the housing is operable to receive an end portion of the cable and to conduct an electric current from the cable to the conductive sleeve; the end portion of the cable is radially sealable within the housing through cable seal of the plurality of seals; the female plug end comprises a housing, a conductive pin, a contact spring, and a female plug sleeve; the conductive sleeve of the male plug end is radially sealable within the housing of the female plug end through plug end seal of the plurality of seals with insertion of the conductive sleeve into the housing of the female plug end; the conductive pin is radially sealed within the female plug sleeve through a conductive pin seal of the plurality of seals and is positioned to insert into the conductive sleeve; the contact spring is operable to enhance conduction between the conductive sleeve and the conductive pin; a female plug sleeve seal of the plurality of seals is provided to an exterior surface of the female plug sleeve that is operable to radially seal the female plug sleeve within a complementary plug end with insertion of the female plug sleeve therein; and the conductive pin is operable to conductively connect to a conductive lead of the complementary plug end with insertion of the female plug sleeve therein.
