Abstract
The utility model relates to a sealing structure for an anode and a glass envelope of an electron tube. The sealing structure comprises the anode and a flange plate sleeved on the anode, and is characterized in that a seam allowance is arranged on the anode, wherein a kovar ring is connected to the seam allowance; the kovar ring is made of a 4J29 alloy; and the glass envelope is sealed on the kovar ring. The sealing structure for the anode and glass envelope of the electron tube has the beneficial effects that the kovar ring is made of the 4J29 alloy, the coefficient of thermal expansion of the kovar ring is similar to that of glass, and the sealing belongs to matching sealing, so that such a sealing structure is anti-explosive. Meanwhile, the anode is connected to the kovar ring through the seam allowance, so that the sealing is tighter.
Description
Technical field
The utility model relates to a kind of anode and glass bulb sealing structure of electron tube.
Background technology
At present, in the assembling process of electron tube, be on the anode of electron tube, to be provided with thin copper bound, this thin copper bound and glass bulb directly carry out sealing-in.This sealing structure belongs to unmatched sealing, and the thermal coefficient of expansion of glass bulb and copper differs greatly, and is prone to burst; And the copper featheredge is poorly sealed, is prone to gas leakage, thereby causes electron tube to lose efficacy.
Summary of the invention
The technical problem that the utility model will solve is to propose a kind of anode and the glass bulb sealing structure that can realize matched seal, seal tight electron tube.
The anode of the electron tube that the utility model relates to and glass bulb sealing structure; Comprise anode, on anode, be set with ring flange, its special character is: on anode, be provided with seam, on seam, be connected with and can cut down ring; The described material of cutting down ring is the 4J29 alloy, is sealed with glass bulb on the ring can cutting down.
The beneficial effect of the utility model is: adopt the 4J29 alloy owing to can cut down ring, its thermal coefficient of expansion is similar with the thermal coefficient of expansion of glass, belongs to matched seal, so this sealing structure can prevent to burst.Simultaneously, anode through seam with can cut down the ring be connected, make sealing tighter.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the enlarged drawing of A portion among Fig. 1.
Among the figure: the 1-anode, the 101-seam, the 2-ring flange, 3-can cut down ring, the 4-glass bulb.
Embodiment
As shown in the figure, the utility model comprises anode 1, on anode 1, is set with ring flange 2, is provided with seam 101 at anode 1 top.On seam 101, be welded with and can cut down ring 3, described to cut down ring 3 material be the 4J29 alloy, is sealed with glass bulb 4 can cutting down on the ring 3.
