High-pressure sealable connector for a pressure sensor

A fuel pressure sensor for detecting fuel pressure in an engine, the sensor comprising:

• a male connector member having:
• a generally cylindrical body with a bore extending centrally therethrough, an outer diameter of said cylindrical body having threads for engagably moving said male connector member in an axial direction;
• a planar annulus formed at a tip of said body adjacently surrounding an opening to said bore;
• a frustoconical section of said body linearly sloping radially outwardly from said planar annulus to said outer diameter of said cylindrical body;
• and
• a planar annular seal disc for compressibly engaging against said planar annulus and at least a portion of said frustoconical section to plastically compress said disc at a radially-inward zone which is radially-outwardly surrounded by a zone of gradually-decreasing elastic compression, said seal disc having a central opening alignable with said bore of said male connector member.

A fluid connector comprising:

• a male member having a generally cylindrical body with an annular tip, a central bore extending longitudinally through said body, said tip having a flat annulus with an inner radius defining said bore and an outer radius, said tip having a frustoconical section extending radially outward from said outer diameter of said annulus to an outer diameter of said body;
• a female member having supporting body with a cavity formed therein to complementarily receive said male member in a threaded engagement, said cavity having a planar bottom with a central bore formed therein;
• and
• a generally planar seal disc having a central bore formed therein, the bore being no larger in diameter than said inner diameter of said annulus, the seal disc being sealably compressible between said bottom of said female cavity and said tip such that the bore of said male member is in fluid communication with the bore of said female member through said central bore of said seal disc;
• whereby, in a mated state wherein said male member inserted in said cavity, the seal disc is caused to plastically compress at a radially-inward zone which is radially-outwardly surrounded by a zone of elastic compression.
