[0002] A server optical module is composed of optoelectronic devices, functional circuits, optical interfaces and other components. The optoelectronic devices include two parts: transmitting and receiving. The optical module is used for optoelectronic conversion. The transmitting end converts an electrical signal into an optical signal, and after being transmitted through an optical fiber, the receiving end converts the optical signal back into an electrical signal. In order to detect the performance and product quality of the server optical module, it needs to be tested. Since there are many types of server optical modules, each server optical module needs to be tested using a circuit board with a corresponding model. Therefore, each test circuit board needs to be installed on a corresponding carrier, which not only increases the test cost, but also occupies more space for a large number of test circuit board carriers.

The test circuit board is slidably sleeved on the second support rod through its mounting holes, and the test circuit board is placed on the second supporting nut. A pressing lock nut for pressing and fixing the test circuit board is also screwed on the second support rod.

[0005] Preferably, it further includes a strengthening support mechanism, which consists of an upper support sleeve, a lower support sleeve and a screw rod. The support sleeve is fixedly installed on the base, the lower end of the screw rod is fixedly installed in the lower support sleeve, and the upper end of the screw rod is screwed into the upper support sleeve.

[0012] The present utility model will be described in detail below in conjunction with the specific embodiments:

[0013] As Figure 1 and Figure 2 shown, a mounting structure of a stage for a server optical module testing mechanism includes a base 1, a first support rod 2, a first supporting nut 21, a bolt 3, an adjusting plate 4, an upper pressing plate 51, a lower supporting plate 52, a second support rod 7, and a test circuit board 9. The first support rods 2 are fixedly installed at the four corners of the base 1 in a rectangular distribution. The lower supporting plate 52 is fixedly installed on the first supporting nut 21. The first supporting nut 21 is screwed and fixedly installed on the first support rod 2. The upper pressing plate 51 is slidably sleeved on the bolt 3. The adjusting plate 4 is provided with a circular adjusting hole 41. The adjusting plate 4 is slidably sleeved on the first support rod 2 through its circular adjusting hole 41. The bolt 3 is screwed into the threaded hole at the top of the first support rod 2. The adjusting plate 4 is pressed and fixed by the upper pressing plate 51 and the lower supporting plate 52. The second support rods 7 are fixedly installed on each adjusting plate 4. Second supporting nuts are fixedly installed on the second support rods 7. The test circuit board 9 is slidably sleeved on the second support rods 7 through its mounting holes, and the test circuit board 9 is placed on the second supporting nut 71. A pressing lock nut 72 for pressing and fixing the test circuit board 9 is also screwed on the second support rod 7.

The lower end of the screw rod 63 is fixedly installed in the lower support sleeve 62, and the upper end of the screw rod 63 is screwed to the upper support sleeve 61. Rotating the upper support sleeve 61 upward to contact and support the adjusting plate 4 can reduce the load of the combination of the adjusting plate 4, the second support rod 7 and the test circuit board 9 on the upper pressing plate 51 and the lower supporting plate 52, avoid bending deformation of the upper pressing plate 51 and the lower supporting plate 52 during long-term use, and extend their service life.

[0015] A through hole is provided at the center of the top of the base 1, and a heat dissipation fan 8 is fixedly installed in the through hole. Turning on the heat dissipation fan 8 can dissipate heat from the test circuit board 9 in the working state, and avoid affecting its stability due to excessive temperature during long-term continuous testing.

[0016] Rubber anti-slip pads are fixedly provided on the bottom surface of the upper pressing plate 51 and the top surface of the lower supporting plate 52. After the upper pressing plate 51 and the lower supporting plate 52 press and fix the adjusting plate 4, it can further prevent sliding displacement between the adjusting plate 4 and the bottom surface of the upper pressing plate 51 and the lower supporting plate 52.

[0017] When it is necessary to replace the test circuit board 9 of other size types, first unscrew the compression lock nut 72, remove the test circuit board 9 to be replaced from the second support rod 7, loosen the bolt 3, and adjust the relative position of the circular adjustment hole 41 of the adjusting plate 4 and the first support rod 2. The test circuit board 9 to be replaced is installed on the second support rod 7 of the adjusting plate 4, tighten the compression lock nut 72 to press and position the test circuit board 9 on the adjusting plate 4, and then tighten the bolt 3 again to press and fix the adjusting plate 4 through the upper pressing plate 51 and the lower supporting plate 52.
