Abstract

[0002] An optical module consists of optoelectronic components, functional circuits, and optical interfaces. The optoelectronic components include a transmitter and receiver. Simply put, the function of an optical module is to convert electrical signals into optical signals at the transmitter end, transmit them through optical fibers, and then convert them back into electrical signals at the receiver end. The transmitter part processes the electrical signal at a specific bit rate, which is then driven by an internal driver chip to drive a semiconductor laser (LD) or light-emitting diode (LED) to emit a modulated optical signal at the corresponding bit rate. An internal automatic optical power control circuit maintains a stable output optical signal power. The receiver part converts the optical signal at a specific bit rate into an electrical signal via a photodetector diode, which then passes through a preamplifier and outputs an electrical signal at the corresponding bit rate.
[0003] However, during the drop test of existing optical modules, the tooling often cannot withstand the force of the drop, causing the optical module to accidentally fall out, which in turn causes damage to the optical module, reduces the stability of the tooling when it falls, and causes external damage to the optical module, reducing its service life. Therefore, further improvement is needed. Utility Model Content

[0028] The present invention provides a drop test tool for an optical module. Figure 1-4 As shown, the optical module drop test tool includes a carrying shell 1, a rotating cover 2 is movably connected to the carrying shell 1 through a rotating shaft, and
[0029] The limiting mechanism is provided on one side of the outer portion of the rotating cover 2, and the limiting mechanism includes:
[0030] A mounting plate 3 is fixedly mounted on the top of the rotating cover 2, and a fixing seat 4 is fixedly connected to the bottom of the mounting plate 3. A connecting rod 5 is provided inside the fixing seat 4. A connecting block 6 is fixedly connected to the bottom end of the connecting rod 5. A positioning rod 7 is fixedly connected to one side of the outer side of the connecting block 6. A spring 8 is fixedly connected to one end of the outer side of the positioning rod 7. The spring 8 is used to drive the positioning rod 7 to rebound after deformation.
[0031] A shell 9 is provided on the outer side of the carrying shell 1, and the spring 8 is located inside the shell 9. A rotating rod 10 is connected to one side of the carrying shell 1 through a bearing. A rotating block 11 is fixedly connected to the outside of the rotating rod 10. A circular plate 12 is fixedly connected to one end of the rotating rod 10. A protective shell 13 is fixedly connected to the outer side of the carrying shell 1. The rotating rod 10 and the protective shell 13 are connected through a bearing. The limiting mechanism is used for a tight connection between the carrying shell 1 and the rotating cover 2.
[0032] The connecting rod 5 is configured to be L-shaped, and the outer surface of the connecting rod 5 is in contact with the fixing seat 4 , which facilitates the sliding operation of the connecting rod 5 .
[0033] One side of the fixing seat 4 contacts one side of the carrying shell 1 , and one side of the rotating block 11 contacts one side of the outside of the connecting block 6 , so that the rotating block 11 can drive the connecting block 6 to move.
[0034] One end of the spring 8 is fixedly connected to one side of the interior of the housing 9 , and the positioning rod 7 is slidably connected to the housing 9 , which facilitates the sliding operation of the positioning rod 7 .
[0035] The bottom of the carrying shell 1 is provided with a plurality of perspective slots, and the interior of the rotating cover 2 is provided with a plurality of perspective windows, which can facilitate observation of the optical module.
[0036] It should be noted that during the drop test of existing optical modules, the tooling often cannot withstand the force of the drop, causing the optical module to accidentally fall out, which in turn damages the optical module, reduces the stability of the tooling during the drop, and causes external damage to the optical module, shortening its service life.
[0037] In this embodiment, when it is necessary to perform a drop test on the optical module, the staff first needs to place the optical module inside the carrying shell 1, and then rotate the rotating cover 2 to merge with the carrying shell 1. After the carrying shell 1 and the rotating cover 2 are merged, the staff needs to rotate the circular plate 12 clockwise. During the rotation process, the circular plate 12 will synchronously drive the rotating rod 10 and the rotating block 11 to rotate. During the rotation process, the rotating block 11 will synchronously drive the connecting block 6 to move outward. During the movement process, the connecting block 6 will synchronously drive the connecting rod 5 and the positioning rod 7 to move. The positioning rod 7 During the movement, the spring 8 will be driven to compress synchronously, and the positioning rod 7 will be retracted into the shell 9. After the connecting rod 5 moves and the fixing seat 4 falls to the corresponding position, the staff will loosen the circular plate 12. Then the spring 8 will quickly stretch and drive the positioning rod 7 and the connecting block 6 to move. During the movement, the connecting block 6 will synchronously drive the connecting rod 5 into the interior of the fixing seat 4, so that the connection between the fixing seat 4 and the connecting rod 5 can be achieved, and then the supporting shell 1 and the rotating cover 2 can be tightly locked, which is convenient for the drop test of the optical module.
[0038] In a further preferred embodiment of the present invention, a positioning mechanism is provided inside the carrier shell 1, and the positioning mechanism includes:
[0039] The threaded rod 14 is arranged inside the bearing shell 1 , and the threaded rod 14 is connected to the bearing shell 1 via threads, which can facilitate the connection work of the threaded rod 14 .
[0040] The outer end of the threaded rod 14 is fixedly connected to a rotating plate 15 , and a plurality of blocks 16 are provided inside the carrying shell 1 to facilitate the rotation of the rotating plate 15 .
[0041] A pad 17 is fixedly connected to one side of the outer portion of each of the blocks 16 . The threaded rod 14 is connected to one of the blocks 16 via a bearing, so that the block 16 can drive the pad 17 to move, and the pad 17 limits the position of the optical module.
[0042] The plurality of blocks 16 are fixedly connected to each other by a limiting plate 18 , and a plurality of empty slots are defined inside the bearing shell 1 .
[0043] The plurality of limiting plates 18 respectively pass through the interior of the plurality of empty slots, and the plurality of limiting plates 18 respectively contact the plurality of empty slots, which can facilitate the connection work of the limiting plates 18 .
[0044] In this embodiment, if optical modules of different sizes need to be tested simultaneously during the test, the staff needs to place the optical module inside the carrier shell 1, and then rotate the turn plate 15. The turn plate 15 will synchronously drive the threaded rod 14 to rotate during the rotation. The threaded rod 14 will enter the interior of the carrier shell 1 during rotation. At this time, the threaded rod 14 will synchronously drive the block 16, the pad 17 and the limit plate 18 to move. When one side of the pad 17 contacts one side of the optical module, the optical module will be limited by the carrier shell 1 and the pad 17, so that the optical modules of different sizes can be tested by dropping at the same time, and the accuracy of the drop test is guaranteed by a certain limit.
[0045] In summary, after the connecting rod 5 moves and the fixed seat 4 falls to the corresponding position, the staff will loosen the circular plate 12, and then the spring 8 will quickly stretch to drive the positioning rod 7 and the connecting block 6 to move. During the movement, the connecting block 6 will synchronously drive the connecting rod 5 into the interior of the fixed seat 4, so that the supporting shell 1 and the rotating cover 2 can be tightly locked working state, which is convenient for the drop test of the optical module.
[0046] Compared with related technologies, the present invention can not only tightly connect the entire device to prevent the optical module from falling, but also limit the position of optical modules of different sizes.
