Example Embodiment
[0038] Example one:
[0039] Such as figure 1 As shown, the airborne radar low-pressure test sealing test device includes a low-pressure test box 1, an expansion device 2, a connector 3, multiple sets of test cables 4, and a test instrument 5; the expansion device 2 has a large end and a small end In the cavity, the small end of the expansion device 2 is an open end, and the open end is hermetically connected to the low-pressure test box 1, the expansion device 2 communicates with the low-pressure test box 1, and the large end of the expansion device 2 is a closed end , The closed end has a through mounting hole, the connector 3 is sealed and installed in the mounting hole, and each set of test cables 4 are used to connect the test instrument 5, the connector 3 and the airborne radar; the connector 3 is more Each set of test cables includes two sections of cables, one of which connects the test instrument 5 and the connector 3, and is located outside, and the other section connec...
Example Embodiment
[0049] Embodiment two:
[0050] Combine Figure 5 As shown, this embodiment is based on the first embodiment above. The airborne radar low-pressure test sealing test device further includes two liquid adapters 6, which are sealed and installed in the mounting hole of the closed end of the expansion device 2. Inside.
[0051] Combine image 3 As shown, two second special-shaped holes 223 are opened in the middle of the test disk 22, which are formed in a circular and arc-shaped structure, and are used to install the liquid adapter joint 6.
[0052] The airborne radar low-pressure test sealing test device also includes three cooling water pipes, one of which is connected to one end of the first liquid adapter 6, and the other water pipe is connected to the other end of the first liquid adapter 6 and passes through Expansion device 2 and enter the low pressure test box 1, and then return to the expansion device 2 from the low pressure test box 1 and then connect the second liquid adapt...
Example Embodiment
[0054] Embodiment three:
[0055] Such as Image 6 As shown, the expansion device 2 in this embodiment is different in structure from the first and second embodiments: the small end of the expansion tube 21 in this embodiment is a cylindrical tube, and the large end is a truncated cone-shaped structure.
