Description

Technical Field

[0001] This utility model relates to the field of optical module testing technology, specifically to vibration testing equipment for finished optical modules used in production. Background Technology

[0002] An optical module consists of optoelectronic devices, functional circuits, and optical interfaces. The optoelectronic devices include both transmitting and receiving parts. The function of the optical module is to convert electrical signals into optical signals at the transmitting end, transmit them through optical fiber, and then convert the optical signals back into electrical signals at the receiving end. When installing an optical module, an installation structure is required. To ensure the robustness of the optical module after installation, vibration testing is necessary.

[0003] Chinese utility model patent CN220751540U discloses a vibration testing device for an optical module, which includes "two third screw grooves 12 are opened at the same end of the side plate 2, and three screw holes 13 are opened at the four corners of the top of the frame 3. When the frame 3 is located at the same end of the two side plates 2, the four third screw holes 13 on the frame 3 are aligned with the four third screw grooves 12 on the two side plates 2 respectively. In this way, the frame 3 can be installed vertically at the same end of the two side plates 2. The stability of the optical module installed in the mounting groove 5 on the mounting plate 4 in the vertical state can be detected by the vibration of the vibration base 1". However, this device uses bolts to connect the frame and the side plates to facilitate the vibration test of the optical module, which makes it inconvenient to adjust the position.

[0009] The further configuration is as follows: the number of arc-shaped grooves is several, and the multiple arc-shaped grooves are distributed in concentric circles, and the arc-shaped grooves have an arc of one-quarter of a circumference.

[0010] By adopting the above technical solution, vibration testing of finished optical modules can be achieved in multiple directions, including horizontal, tilt, and vertical.

[0025] The position adjustment mechanism 3 includes an arc-shaped slide 301. A connecting rod 302 is slidably connected to the inner wall of the arc-shaped slide 301. A transmission shaft 303 is fixedly connected to the connecting rod 302 outside the vertical plate 2. A rotating shaft 304 is rotatably connected to one end of the transmission shaft 303. The rotating shaft 304 is located at the center of the arc-shaped slide 301. The vertical plate 2 is fixedly connected to the rotating shaft 304. Several limiting holes 305 are distributed in a ring outside the arc-shaped slide 301 on the outer side of the vertical plate 2. A limiting rod 306 is movably sleeved on the inner wall of the limiting hole 305. The outer wall of the limiting rod 306 is threadedly connected to the inner wall of the transmission shaft 303. A knob 307 is fixedly connected to one end of the limiting rod 306 on the outer wall of the transmission shaft 303.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, there are several arc-shaped grooves 301, and the multiple arc-shaped grooves 301 are distributed in concentric circles. The arc-shaped grooves 301 have an arc of one-quarter of a circle.

According to the test requirements, the transmission shaft 303 can be rotated around the rotating shaft 304, so that the connecting rod 302 slides on the inner wall of the arc-shaped slide groove 301. When it moves to the appropriate position, the knob 307 is rotated so that the limiting rod 306 is engaged with the limiting hole 305 at the corresponding position, thereby fixing the angle position with the connecting rod 302. Thus, the frame body 401 can be placed at horizontal, inclined and vertical angles as needed. The vibration chassis 1 is started to perform vibration test on the optical module body 5.
