Embodiment 1

[0030] This embodiment provides a high-reliability ceramic thermal insulation window assembly. figure 1 A schematic structural view of the high-reliability ceramic heat-insulating window assembly of this embodiment is shown.

[0031] Such as figure 1 As shown, the high-reliability ceramic heat-insulating window assembly of this embodiment includes a ceramic heat-insulating window main body 1 , a connecting piece 2 and a buffering piece 3 . Among them, the main body 1 of the ceramic heat-insulating window includes a hollow cavity surrounded by the side wall 11 and the upper wall 12, and a flanging structure 13 that is turned outward from the bottom of the side wall 11; the buffer member 3 is located on the flanging structure 13; the connecting member 2 It is in contact with the buffer piece 3, and the flange structure 13 can be pressed by the buffer piece 3. The connecting piece 2 has a mounting part 21 for fixing the connecting piece 2 so that the flange structure 13 can be f...

Embodiment 2

[0040] This embodiment provides a high-reliability ceramic thermal insulation window assembly. figure 2 A schematic structural view of the high-reliability ceramic heat-insulating window assembly of this embodiment is shown.

[0041] The difference between the high-reliability ceramic heat-insulation window assembly of this embodiment and the embodiment 1 is that: the height of the connecting piece 2' is greater than the flange structure 13'; the high-reliability ceramic heat-insulation window assembly also includes a rubber gasket 6 ', the rubber gasket 6' is located under the flange structure 13' and the side wall. Other parts of the high-reliability ceramic heat-insulating window assembly in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

[0042] This embodiment also provides a method for assembling the high-reliability ceramic heat-insulating window assembly of this embodiment, including the following steps:

[0043] Provide a cera...

Abstract

The invention provides a high-reliability ceramic heat insulation window assembly. The high-reliability ceramic heat insulation window assembly comprises a ceramic heat insulation window body, a connecting piece and a buffering piece. The ceramic heat insulation window body comprises a hollow cavity defined by a side wall and an upper wall and a flanging structure turned outwards from the lower portion of the side wall. The buffer piece is positioned on the flanging structure; the connecting piece makes contact with the buffering piece, the flanging structure can be pressed by means of the buffering piece, the connecting piece is provided with an installation part used for fixing the connecting piece so that the flanging structure can be pressed by pressing the buffering piece through the connecting piece, and the heat insulation window body can be fixed to the preset fixing position. The connecting piece is fixed through the mounting part, and the connecting piece is in press fit with the buffer piece to indirectly press the flanging structure, so that the heat insulation window body is fixed, that is, the heat insulation window body is fixed through non-direct contact of the connecting piece and the flanging structure, and the problems that stress concentration is formed by mechanical connection of the heat insulation window and the connecting piece, and the heat insulation window is prone to being damaged and cracked are solved; the buffering piece plays a buffering role, disperses stress and further avoids stress concentration.

Description

technical field [0001] The invention relates to the technical field of heat-insulating windows, in particular to a high-reliability ceramic heat-insulating window assembly and an assembly method thereof. Background technique [0002] With the development of aerospace technology, there are more and more demands for thermal insulation window components of aircraft guidance antennas, and there are more and more application requirements for low-cost, high-reliability thermal insulation window component materials. At present, the wave-transparent heat-insulation materials used in the high-temperature field of heat-insulation window parts are ceramic materials and their composite materials. Among them, the commonly used high-reliability wave-transparent heat-insulation window materials generally use quartz fiber reinforced composite materials, but there is a preparation cycle. Shortcomings such as length and high price limit its large-scale application. For this reason, technicia...
