Currently, users have higher requirements for the operating environment temperature of microwave components. In particular, the military or aerospace industry requires the product operating temperature to be between -65℃ and 125℃.

DETAILED DESCRIPTION

[0023] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0024] Example:

[0025] Reference Figures 1-6 A carrier for low-temperature testing of microwave components includes a placement platform 1. Two sets of movable seats 4 are slidably connected to the top of the placement platform 1. The bottoms of the two sets of movable seats 4 are provided with a centering mechanism for facilitating the adjustment of the spacing between them. One side of the two sets of movable seats 4 is equipped with a clamping mechanism for facilitating the fixation of microwave components of different specifications.

[0026] The clamping mechanism includes a motor 12, and multiple groups of grooves 9 are provided on one side of the movable seat 4. The inner sides of the multiple groups of grooves 9 are penetrated by a rotating plate 10, and the interiors of the multiple groups of rotating plates 10 are penetrated by a connecting shaft 11 that is rotatably connected to the movable seat 4. One end of the connecting shaft 11 extends to the outside of the movable seat 4 and is connected to the output end of the motor 12. Both sides of the rotating plate 10 are rotatably connected to a connecting frame 13 near the end, and an upper pressure roller 14 that contacts the top of the microwave component and a lower pressure roller 15 that contacts the side of the microwave component are rotatably connected between the two groups of connecting frames 13.

[0027] Specifically, the placement table 1 is provided to provide a stable working platform for the detection operation of the microwave component. The centering mechanism is provided to facilitate the adjustment of the spacing between the two groups of movable seats 4, thereby facilitating the testing and installation of microwave components of different specifications and sizes. When multiple microwave components are placed on the top of the placement table 1, by rotating the two groups of motors 12, the two groups of motors 12 can drive the two groups of connecting shafts 11 to rotate, and the two groups of connecting shafts 11 can drive the corresponding multiple groups of rotating plates 10 to rotate, and the multiple groups of rotating plates 10 can drive the corresponding connecting frames 13 to rotate, and the connecting frames 13 can drive the upper pressure roller 14 and the lower pressure roller 15 to clamp and fix the microwave component. Through the above structure, the installation and disassembly of the microwave component can be facilitated, and the work efficiency is improved. At the same time, it can be suitable for the testing and installation of microwave components of different specifications and sizes, thereby improving the applicability of the device.

[0028] Among them, both sides of the rotating plate 10 are provided with a limit plate 16 for limiting the rotation range of the connecting frame 13. The limit plate 16 can limit the rotation range of the connecting frame 13, and the connecting frame 13 can drive the upper pressure roller 14 and the lower pressure roller 15 to adaptively clamp and fix the microwave component. The outer rings of the upper pressure roller 14 and the lower pressure roller 15 are both sleeved with protective sleeves. The protective sleeves can provide protection for the clamped microwave component.

[0029] Among them, the centering mechanism includes a driving motor 8, a cavity 2 is opened on the inner side of the placing table 1, and two groups of support rods 3 are provided on the inner side of the cavity 2.

Therefore, the applicability of the device is greatly improved through the setting.
