Abstract
一种多级降压收集极组件非焊接装配方法，根据收集极的级数N将整个陶瓷筒沿轴向分成N个圆弧；每一个圆弧的内弧面上开设有至少一个收集极电极定位用的凹槽；在每一个圆弧上开有安装收集极各引线的通孔；N个圆弧排列围绕多级收集极合成一个陶瓷筒，且每级收集极的电极上的凸棱与相对应的圆弧内的凹槽配合定位，多级收集极的各极引线从通孔内引出，再将由圆弧排列成的陶瓷筒置于收集外套筒中，使多级收集极、圆弧排列成的陶瓷筒和收集极外套筒紧密装配在一起。本发明可以解决传统多极降压收集极的散热问题、绝缘问题、可靠性问题和寿命问题。
A non-welding assembly method for a multi-stage step-down collector assembly, in which the entire ceramic cylinder is divided into N circular arcs along the axial direction according to the number of collector stages N; at least one collector electrode is provided on the inner arc surface of each circular arc A groove for positioning; each arc has a through hole for installing the lead wires of the collector; N arcs are arranged around the multi-stage collector to form a ceramic cylinder, and the ribs on the electrode of each collector are aligned with the The grooves in the corresponding circular arcs are positioned together, and the lead wires of each pole of the multi-stage collectors are drawn out from the through holes, and then the ceramic sleeves arranged by the circular arcs are placed in the outer sleeve of the collector, so that the multi-stage collectors, circular The arc-arranged ceramic sleeve and the collector outer sleeve are tightly fitted together. The invention can solve the problems of heat dissipation, insulation, reliability and service life of the traditional multi-pole step-down collector.
Description
Technical field
The present invention relates to a kind of multi-level depressurization collector component assembling method, relate to the non-welding assembly method of a kind of multi-level depressurization collector assembly particularly.
Background technology
Multi-level depressurization collector adopts welding method at present.During collector work, along with the rising of temperature in the collector, scolder will evaporate gradually and attached to the insulating ceramics surface, its insulating capacity be descended, and directly influence stability and service life.
Summary of the invention
The object of the present invention is to provide the non-welding assembly method of a kind of multi-level depressurization collector assembly, can solve the defective that exists in the background technology.
For achieving the above object, method provided by the invention is according to the progression N of collector whole pottery tube to be divided into N circular arc vertically, and these N circular arc can be combined into a complete circle.
On the intrados of each circular arc, offer the groove of at least one collector electrode location usefulness.
On each circular arc, have the through hole that each lead-in wire of collector is installed.
N circular arc arranged around the synthetic pottery tube of multistage collector, and the location of the groove fit in fin on the electrode of every grade of collector and the corresponding circular arc, each utmost point lead-in wire of multistage collector is drawn in through hole, to place by the pottery tube that circular arc is arranged in again and collect outer sleeve, the pottery tube that multistage collector, circular arc are arranged in will be in the same place with collector outer sleeve close fit with hot extrusion technique.
Pottery tube of the present invention can adopt the beryllium oxide material.
The present invention does not adopt the scolder welding and firmly fixes each assembly, each ceramic multistage collector, collector outer sleeve surface is fully contacted, and have certain pressure, well heat conduction.When collector is worked, though the liter of temperature very high, do not have scolder evaporative emission pottery yet, its insulating capacity is descended.The stability and the life-span of product have so just been guaranteed.
Description of drawings
Fig. 1 is a side of the present invention cross-sectional schematic.
Fig. 2 is the vertical view schematic diagram of Fig. 1.
The specific embodiment
See also illustrated in figures 1 and 2.Fig. 1 is a side sectional view of the present invention.The pottery tube 11 of pottery (as aluminium oxide, beryllium oxide etc.) material is installed coaxially in the inside of collector outer sleeve (adopting heat conduction good metal material) 10, this pottery tube axially is divided into 3 circular arcs 121,122 and 123, and (progression of the collector among Fig. 2 is example with 3, therefore the pottery tube is divided into 3 circular arcs vertically, promptly each circular arc be pottery tin 1/3rd).Offer groove 12 and through hole 13 on the medial surface of each circular arc, this groove 12 is the fins 131 on the ccontaining fixedly collector electrode 13, and collector can be located in circular arc; This through hole 14 is used to draw the lead-in wire of each utmost point of collector.
The fin 131 of collector electrodes 13 at different levels is placed the groove 12 of circular arc 121,122,123 respectively, three circular arcs 121,122,123 are combined into a complete circle, place in the collector outer sleeve 10, make pottery tube and each electrode of collector, collector outer sleeve tight fit, use known hot extrusion assembly technology then together three's close fit.Even also can firmly fix each assembly without the scolder welding like this, each pottery fully contacts with electrode, sleeve surface, and has certain pressure, heat conduction well.
Do not use scolder among the present invention, when collector is worked, even the liter of temperature very high, do not have scolder evaporative emission pottery yet, its insulating capacity is descended.The stability and the life-span of product have so just been guaranteed.
