  • Patent number: 10249980
    Abstract: The present invention provides a system for providing a stress reduction apparatus for a ceramic electrical penetrator or pin in a subsea environment. More specifically, the present invention provides a deformable translatable seat in an annular pocket that prevents the transfer of shear forces from a shell or fixture to a ceramic electrical penetrator or pin. The present invention provides a relatively soft metal seat that conforms to the profile of the shoulder of a mating electrical penetrator or pin and deforms to reduce or eliminate concentrated bearing stresses. The deformable translatable seat may also shift and deform within the annular pocket to relieve shearing stresses exerted on the electrical penetrator or pin by the shell or fixture.
    Type: Grant

  • Patent number: 9397430
    Abstract: An isolated electrical connection assembly having first and second conductive terminals of different conductive materials with a non-metallic, annular spacer sandwiched between opposing inner end faces of the terminals. The first terminal having a bore extending inwards from its inner end face, and a pin projects from the opposing inner end face of the second terminal, through a central opening in the spacer, and into the bore. The pin is releasably secured in the bore to provide electrical connection between the terminals. The interfaces between the inner end faces of the terminals and opposing faces of the spacer are sealed to isolate the connection between the second terminal pin and the first terminal bore.
