Description
Technical field
The utility model is related to a kind of cathode base column assembly and X-ray tube.
Background technology
Vacuum sealing is one of most important index in vacuum products design and production process, from encapsulant type
On see that most commonly seen vacuum sealing material includes the vacuum sealing between metal and glass, metal and pottery, metal and metal；
Seal washer, machinery, various welded seal etc. are comprised from vacuum-packed mode, and for X-ray tube, particularly big work(
For rate, high heat capacity X-ray tube, work under high temperature, high voltage for a long time it is desirable to X-ray tube is internal keeps high vacuum for a long time
State, requires extremely strict to each sealing area sealing state, and some casts even require sealing leak rate to be not higher than 10-
11Pa.m3/s.
At present, most of X-ray tube cathode base column assemblies adopt plain conductor and glass infiltration sealing, plain conductor and pottery
The mode of porcelain sealed with brazing, plain conductor and metal base sealed with brazing, but because plain conductor diameter is less, all there is circuit
Connecting or subsequent operation process wire is not enough because of structural strength, easily being rotated distortion by external force effect, thus destroying former
The seal interface come, produces X-ray tube air leakage failure.And, multiple connecting wires, once there being a lead to produce gas leakage, whole
Individual cathode base column assembly is scrapped, if negative electrode stem stem completes with the miscellaneous part of cathode assembly to weld, can cause bigger
Waste.

Metal Substrate base, this Metal Substrate base is provided with several through holes, is fixed with wire lead assemblies in each through hole；This wire
Lead assemblies include lead wire of conductor, lead cap, wire holder and insulating ceramics connector, and this wire holder and lead cap seal admittedly respectively
Due to the two ends of this insulating ceramics connector, the center of this lead cap and this insulating ceramics connector is correspondingly provided with through hole even respectively
Pass to described wire holder, institute is fixed on after sequentially passing through this lead cap and this insulating ceramics connector in one end of described lead wire of conductor
State on wire holder；Described wire lead assemblies are sealingly fastened in the through hole of described Metal Substrate base by described lead cap lateral surface
Interior, and described lead wire of conductor passes in this through hole.
As further improvement of the utility model, the outer face of described wire holder is provided with screwed hole.
As further improvement of the utility model, described wire holder and lead cap are fixed on institute by sealed with brazing respectively
State the two ends of insulating ceramics connector.
As further improvement of the utility model, described lead cap passes through machinery, soldering, argon with described Metal Substrate base
Arc-welding or electron beam weldering are tightly connected.
The utility model also provides a kind of X-ray tube, including cathode assembly, anode assemblies and black box, described negative electrode
Assembly includes cathode base column assembly as above and negative electrode head assembly.
As further improvement of the utility model, described black box includes sealing shell and in this sealing shell
Radiation exit window, described cathode base column assembly is fixed on the side of this sealing shell by its Metal Substrate base, this metal
The medial surface of base seat is connected with negative electrode head assembly by connecting cylinder.
As further improvement of the utility model, described anode assemblies include anode disc, bearing assembly and rotor set
Part.
The beneficial effects of the utility model are：
(1) wire holder and lead cap are larger-size structural design, and this construction machine machining accuracy and soldering are welded
Connect intensity and stability high, and lead is from the installation in the hole being internally embedded wire holder, the thinner lead of string diameter will not be subject to external force
Draw or rotate and lead to the generation of gas leakage；
(2) wire holder external connection opens screwed hole, and cathode terminal and X-ray tube wire connections divide and can adopt the side of being screwed
Formula, thus avoid some X-ray tube using scolding tin welded cathode connecting lead wire because rosin joint or not prison welding are by drawing of causing
Line obscission；
(3) independent conductor lead assemblies can independently be hunted leak, and the production technology of whole stem stem assembly is only
Contain the simple assembling of a step and lead cap and the sealing technology of Metal Substrate base, greatly reduce and make because soldering processes are unstable
The air leakage failure frequency becoming.
In sum, this cathode base column assembly and X-ray tube possess independent wire lead assemblies of can hunting leak, can be great
Improve X-ray tube quality, reduce the use cost of sigmatron pipe, promote the industrialization at home of sigmatron pipe.
