  • Underwater connector with electrical stress reduction
    Patent number: 6659780
    Abstract: A connector for making an electrical connection underwater or in a wet environment, comprising first and second connector parts for engagement with each other to establish the electrical connection, the first connector part having a connecting pin provided with an insulating layer around a conductive core leading to a first electrical contact portion, the second connector part having a second electrical contact portion for engagement by the first electrical contact portion, and the second connector part having a seal arranged so that in the mated condition of the connector the connecting pin extends forwardly through an opening in the seal, the first electrical contact portion then making contact with the second electrical contact portion, wherein an earthing conductive layer is provided around the insulating layer for reducing electrical stress at the seal when the connecting pin passes therethrough.
