Abstract
A connector between an x-ray tube and high voltage source. An epoxy-filled housing is connected to the casing or housing of an x-ray tube or vacuum vessel. A high conductivity silicone gasket is positioned between the ceramic insulator of the x-ray tube and the epoxy material in the housing. Air is evacuated in the joint between the connector housing and x-ray tube vessel and a vacuum created therein. Appropriate seals are positioned maintaining the integrity of the vacuum. Spring-loaded attachment bolts are also utilized to secure the connector housing and vacuum vessel casing together.
Claims24
A method of securely attaching a high voltage connector device to a vacuum vessel, said method comprising the steps of:
- assembling said connector device on said vacuum vessel, said vacuum vessel having a vessel container and insulator member and said connector device having a first connector housing filled with an insulating material;
- positioning a substantially flat gasket member between said first connector housing and said insulating material, said gasket member being made from a silicone material;
- said insulator member having a first substantially planar surface and said insulating material having a second substantially planar surface;
- positioning a second connector housing over said first connector housing leaving an annular space between them;
- cooling the annular space between said first and second housing members with a cooling fluid;
- pulling a vacuum and thereby removing the air in the space between said connector device and said insulator member, thereby compressing said gasket member between said first and second substantially planar surface;
- and
- securing said connector device to said vacuum vessel.
A high voltage connector for connecting a high voltage source to a vacuum vessel, the vacuum vessel having an insulator member, said connector comprising:
- a first housing member having a central cavity;
- an insulating member positioned in said central cavity;
- a substantially flat silicone gasket member positioned adjacent said insulating member;
- a second housing member positioned over said first housing member leaving an annular space therebetween;
- wherein when said connector is connected to said vacuum vessel, the gasket member is compressed between said insulating member and said insulator member;
- and
- wherein said annular space between said first and second housing members can be cooled by circulation of a cooling fluid.
A high voltage connector for connecting a high voltage source to a vacuum vessel, said connector comprising a first housing member having a central cavity, insulating material positioned in said central cavity, said insulating material having a substantially planar surface, a gasket member, said gasket member being made from a silicone material and having at least one substantially planar surface positioned in direct contact with said insulating material's substantially planar surface;
- a second housing member positioned over said first housing member and leaving a cavity therebetween, and means for cooling said cavity between said second housing member and said first housing member, wherein when said connector is connected to the vacuum vessel, the gasket member is compressed creating a tight seal.
A method of securely attaching a high voltage connector device to a vacuum vessel, said method comprising the steps of:
- assembling said connector device on said vacuum vessel, said vacuum vessel having a vessel container and insulator member and said connector device having a first connector housing member filled with an insulating material;
- positioning a highly conductive gasket member between said first connector housing member and said insulating material;
- positioning a second connector housing member over said first connector housing member leaving an annular cavity therebetween;
- cooling said annular cavity with cooling means;
- pulling a vacuum and thereby removing the air in the space between said connector device and said insulator member;
- and
- securing said connector device to said vacuum vessel.
A high voltage connector for connecting a high voltage source to a vacuum vessel, said connector comprising:
- a first housing member having a central cavity and an annular flange, said first housing member filled with an insulating material;
- a high conductivity silicone gasket member, said gasket member having a central cavity for allowing connection of a high voltage source to a vacuum vessel;
- and
- a second housing member positioned over said first housing member and leaving an annular space therebetween for circulation of a cooling fluid thereon.
