Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] Such as figure 1 and 2 As shown, a sealing structure of a large-sized microwave output window includes a basic copper ring 1 with an annular mounting boss 2 inside the basic copper ring 1, and a disc-shaped microwave output window 3 is set on the annular mounting boss 2 Above, the specific material of the microwave output window 3 is sapphire, and an annular solder sheet 4 is arranged between the upper surface of the annular mounting boss 2 and the lower surface of the microwave output window 3, and the annular solder sheet 4 is specifically a silver-copper-titanium solder sheet , and realize the sealing and fixing between the upper surface of the annular mounting boss 2 and the lower surface of the microwave output window 3 through the annular solder sheet 4 .

[0021] Further, an additional copper ring 5 is set inside the basic copper ring 1, the outer diame...

Abstract

The invention relates to the technical field of microwave output window sealing and discloses a sealing structure of a large-sized microwave output window. The structure comprises a basic copper ring,an annular mounting boss is inside the basic copper ring, a circular-plate-shaped microwave output window is disposed on the annular mounting boss, an annular soldering piece is disposed between an upper surface of the annular mounting boss and a lower surface of the microwave output window, and the annular sealing and fixation between the upper surface of the annular mounting boss and the lowersurface of the microwave output window is achieved through the annular soldering piece. The sealing structure has reasonable and reliable structure, metalizing the window is not needed, the process flow is simplified, the requirement for an assembling gap and welding process between the window and the copper ring are reduced, the welding reliability is improved, the sealing effect between the window and the copper ring is effectively ensured, and the welding yield is high.

Description

technical field [0001] The invention relates to the technical field of microwave output window sealing, in particular to a sealing structure of a large-size microwave output window. Background technique [0002] An electric vacuum device is a device that converts electron kinetic energy into electromagnetic wave energy. The interior of the device is a vacuum environment, and the electromagnetic waves generated by the electron beam inside the device need to be output to the outside of the device through a window (a medium transparent to electromagnetic waves). Sapphire is a commonly used window material. [0003] The existing implementation scheme is to first metallize the edge of the sapphire window, and then use silver-copper solder to braze the window and the metal copper ring to realize vacuum sealing. The existing metallization technology is prone to defects when dealing with large sizes (diameter greater than 60mm), and has high requirements for the fit gap between the...
