Connector
First Claim
1. A connector for making an electrical connection underwater or in a wet or conductive environment, the connector 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 insulating layer being partially screened by a screening conductive layer, 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 when the connecting pin passes through the seal, the screening conductive layer is arranged to reduce electrical stress at the seal.

18. A connector for making an electrical connection underwater or in a wet or conductive environment, the connector comprising a first connector part and a second connector part, the first and second connector parts being adapted 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 insulating layer being partially screened by a screening conductive layer which has a front end portion, an inner surface of the front end portion curving towards an outer surface thereof, and a further insulating layer being provided around the conductive layer, 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 first seal and a second seal arranged so that in the mated condition of the connector the connecting pin extends forwardly through respective openings in both the first and second seals, the first electrical contact portion then making contact with the second electrical contact portion, wherein when the connecting pin passes through the seals, the screening conductive layer is arranged to reduce electrical stress at the seals, and wherein the conductive layer is arranged so that in the mated condition it extends at least partly into the second seal opening, the connector further comprising a corrosion resistant shield, provided on the outside of the connecting pin so as to protect the connecting pin from the external environment when the first and second connector parts are in the mated condition.
