Isolated coaxial high-pressure feed-through fitting

  • US Patent No. 9021960
  • Issued: May 05, 2015
  • Status: Active

An isolated, coaxial, high pressure feed-through fitting provides two electrical paths through a barrier. The fitting includes an outer dielectric disposed in an opening in the barrier. A conductive housing with a central through bore is disposed in the outer dielectric. An inner dielectric is disposed in the through bore in the conductive housing. A central conductor is disposed in the inner dielectric. One electrical path includes the central conductor and another electrical path includes the conductive housing. Flanged portions on the conductive housing and the central conductor bear on flanged portions of the outer dielectric and the inner dielectric, respectively, to create a high pressure seal.
