ABSTRACT:
An electrical connector has a female portion with tubular socket assemblies extending into it that are coated with a thin dielectric film over their surfaces with the exception of their internal electrical contact bands. The socket assemblies and the interior of the female portion are immersed in a dielectric fluid, the pressure which is equalized to that of the surrounding environment. Spring-biased pistons are located within openings in resilient seals at the open ends of the socket assemblies to seal the interior of the socket assemblies against the environment. When the portions are mated, pins on the male portion are wiped by the resilient seals and depress the pistons past the contact bands as they enter the socket assemblies. The pins are also coated with the dielectric film with the exception of thier conductive tips, which contact the contact bands. The thin dielectric coating allows the connector to be reduced in size.
