Abstract
The collector of an electronic power tube is surrounded by a ceramic sleeve and a heat-sink. Between these three parts two resilient assemblies, are placed respectively one having anchorage points on the collector and the ceramic sleeve, and the other having anchorage points on the ceramic sleeve and the heat-sink. The two assemblies are formed from pieces able to be deformed both in the cross-sectional planes and along the axis of the system.
Claims7
An insulator electron collector assembly for electronic tubes, comprising two metal parts concentrically disposed along an axis, forming respectively an inner collector and an outer sleeve and further comprising a third part made of insulating material located therebetween, a first series of resilient members located between said inner collector and said third part, a second series of resilient members located between said third part and said outer sleeve, said resilient members consist of elements stacked in the direction of said axis, and which elements comprise on both sides interdigitated projecting parts distributed on the periphery of the elements by which they rest against the parts between which they are located.
An insulator electron collector assembly for electronic tubes, comprising two metal parts concentrically disposed along an axis, forming respectively an inner collector and an outer sleeve;
- a third part made of insulating material located therebetween;
- a first series of resilient members located between said inner collector and said third part;
- a second series of resilient members located between said third part and said outer sleeve;
- said resilient members comprising elements stacked in the direction of said axis, and which elements comprise on both sides projecting parts distributed on the periphery of the elements by which they rest against the parts between which they are located, the resilient members of each series are constituted by two different sets of resilient members, each comprising, along generatrices of cylinders having for axis the axis of said resilient members, bars, a backbone and flexible slits in which the flexible slits separate parts of bars in the first set of resilient members and parts of backbone in the second set of resilient members.
