Embodiment 1

[0016] refer to figure 1 , figure 2 , the metal elastic support spacer used under deep and low temperature conditions, the material is forged Kovar alloy, machined into a dome-shaped structure with a wall thickness of 0.2mm and a central opening of 1-1, the outer diameter of the support spacer is 15mm, and the height is 5mm , The central opening diameter is 10mm. The lower elastic support sheet is obtained by radially slotting 1-2, the number of slots is 8, and the slots are evenly distributed along the circumferential direction, the slot width is 0.2mm, and the length is 2.2mm. The width of the tangential slot 2-1 of the side elastic support ring structure is 0.2mm, the width of the support column 1-3 between the slots is 0.4mm, and the number of tangential slots 2-1 on each ring is 4 and distributed evenly along the circumferential direction . The grooved rings are located in the middle of the support ring, the number is 4, and the distance between the rings is 0.4mm. St...

Embodiment 2

[0018] refer to image 3 , Figure 4 , is the second example of metal elastic support for the deep low temperature detector of the present invention. This example is roughly the same as the previous example, the difference is that the lower elastic support sheet is obtained by radially opening fan-shaped holes 3-1, the number of openings is 8, the radial length is 1.8mm, and the fan-shaped angle is 20°, along the circumferential direction Evenly distributed, the front end retains a support ring 3-2. The starting positions of the slots on the upper and lower adjacent rings of the side elastic support ring are tangentially rotated by 45°.

Abstract

The invention discloses a metallic elastic supporting space ring applied under a low-temperature working condition, in particular a circular cover-shaped elastic supporting space ring capable of flexibly fixing a lens or other elements in a deep low-temperature detector. An elastic element is made of forging expansion alloy so that the elastic element keeps good hot matching property with the lens or other element material. The elastic element has an integrated structure and has no multi-member connection, so the elastic element is convenient to process and use; and the lower end face and thelateral surface of the selected cover-shaped structure are provided with grooves or holes in a mode of machining or laser cutting or the like, and the stiffness coefficient of the whole elastic element can be changed by adjusting the number, distance, arrangement mode and the like of the grooves or the holes so as to meet the specific application requirements of different detectors.

Description

technical field [0001] The invention relates to a metal elastic spacer, in particular to a dome-shaped elastic support spacer which can flexibly and parallelly fix a lens or other components in a deep low temperature detector. Background technique [0002] Cryogenic detectors are widely used in satellites, and the vibration of various components during transportation and satellite launch must be considered in the design of detector components. Usually, the relative position of the components is fixed by designing tight-fitting slots on the tube shell. However, due to the different mechanical properties of the shell material and other components (such as lens sheets), the optical components will be worn and damaged during the vibration process. An effective way to solve this problem is to design relatively loose card slots or steps and use elastic support elements. Most of the existing elastic support elements can only be used at room temperature, and the application at low...
