Problems solved by technology

[0005] The technical problem to be solved by the present invention is: the effective welding area of ​​the energy transmission window in the prior art is getting smaller and smaller, which leads to the problem that the metallization of the box-shaped window is difficult at present, and the purpose is to provide a double-concave diamond energy transmission window. Through the optimization of the structure, the side welding area can be effectively increased while maintaining the power loss and standing wave ratio of the energy transmission window, and the metallization area of ​​the window can be increased, making the metallization of the current box-type window easier; and, The invention also provides a preparation process for a double-concave diamond energy transmission window, which overcomes the problems that the traditional window welding method may cause cracking of the metallized layer or insufficient packaging strength through the optimization of the welding process, and further Improve window yield

Embodiment 1

[0035] Double concave diamond energy transmission window, such as Figure 3-Figure 4 As shown, it mainly includes: a first rectangular waveguide 11 , a first circular waveguide 12 , a diamond window 13 , a second circular waveguide 14 and a second rectangular waveguide 15 . The diamond window 13 is a double-concave diamond window, which is sealed and welded in the middle of the first circular waveguide 12 and the second circular waveguide 14, and the first rectangular waveguide 11 and the second rectangular waveguide 15 are respectively welded on the first circular waveguide 12 and the second circular waveguide 14. The other side of the second circular waveguide 14. The energy transmission window metallization area described in the present invention is as image 3 The slashed part shown.

[0036] In this embodiment, the specifications of the first rectangular waveguide 11 and the second rectangular waveguide 15 are 2.54mm×1.27mm×3mm. The inner radius R of the first circular...

Embodiment 2

[0043] The difference between this embodiment and Embodiment 1 is that the structure of the energy transmission window is optimized in this embodiment, such as image 3 As shown, the settings are as follows:

[0044] A groove 16 is arranged on the annular side of the diamond window 13 , and the groove 16 is an annular groove arranged along the annular side of the diamond window 13 . The cross-sectional shape of the annular groove can be various, such as semicircle, semiellipse, V-shape, V-like structure and the like. In this embodiment, the cross section of the groove 16 is preferably configured as a "V"-like structure, that is, a V-like shape composed of arc-shaped surfaces, such as image 3 shown. Since the groove 16 is arranged around the side of the diamond window 13, it can effectively function as a solder guide groove, reducing the risk of contamination of the window.

[0045] At the same time, during the preparation process, the shape of the inner wall of the semicir...

Abstract

The invention discloses a double concave diamond energy transmission window and a preparation process thereof, which solve the problem that the effective welding area of a window sheet of an energy transmission window in the prior art is smaller and smaller, thus leading to difficulty of metallization of a box type window. The window includes a first rectangular waveguide, a first circular waveguide, a diamond window sheet, a second circular waveguide, and a second rectangular waveguide that are sequentially connected, and a surface of the diamond window sheet orienting to the first circular waveguide or / and the second circular waveguide is disposed as an inwardly-concave cambered surface. The window achieves the effect of effectively increasing the metallized area without substantially changing the size of the box type window.

Description

technical field [0001] The invention relates to the field of vacuum electronic devices, in particular to a double-concave diamond energy transmission window and a preparation process thereof. Background technique [0002] In microwave electric vacuum devices such as traveling wave tubes, klystrons, gyrotrons, and magnetrons, the microwave energy transmission window is a component that inputs and outputs energy for the microwave tube and plays a very important role. The vacuum state, on the other hand, realizes low-loss or even lossless transmission of energy between the microwave tube and the external transmission line. Its performance directly affects the working performance of the microwave tube, including the working frequency band, gain and gain flatness of the tube. [0003] The traditional box-type energy transmission window structure, such as figure 1 As shown, the structure includes rectangular waveguides (1a) and (1b), circular waveguides (2a) and (2b), and a diele...
