Abstract
An electrical conductor includes an electrically non-conductive plate, an electrically conductive pin extending through the plate, and a frame member fitted around an outer edge of the plate. The frame member is configured to pre-load the plate with a compressive stress. In particular, the frame member may pre-load the plate with the compressive stress that is sufficiently high enough such that a sum of the compressive stress, tensile stress, and shear stress components generated in the plate under high-pressure conditions is compressive overall.

An electrical conductor, comprising:
- an electrically non-conductive plate;
- an electrically conductive pin extending through the plate;
- and
- a frame member fitted around an outer edge of the plate that pre-loads the plate with a compressive stress.
A method of fabricating an electrical conductor, comprising:
- cooling an electrically conductive pin with respect to an electrically non-conductive plate;
- extending the pin through the plate;
- and
- shrink-fitting the plate around the pin such that the plate applies a compressive stress to the pin.
A method of fabricating an electrical conductor, comprising:
- extending an electrically conductive pin through an electrically non-conductive plate;
- and
- shrink-fitting a frame member around an outer edge of the plate at a temperature such that the frame member applies a compressive stress to the plate at any temperature below the shrink-fitting temperature.
A system to measure properties of a high-pressure fluid, the system comprising:
- an electrically non-conductive plate configured to be exposed to the fluid;
- an electrically conductive pin extending through the plate such that the pin is configured to be in contact with the fluid to be measured;
- and
- a metallic frame member fitted around an outer edge of the plate and configured to pre-load the plate with a compressive stress that is sufficiently high such that a sum of the compressive stress, tensile stress, and shear stress components generated in the plate is overall compressive.
