Description

Technical Field

[0001] The invention relates to the technical field of optical fiber communication modules, in particular to an optical fiber communication module with good waterproof performance. Background Art

[0002] The function of the optical module is to convert electrical signals into optical signals at the sending end. After being transmitted through optical fibers, the receiving end converts the optical signals into electrical signals again, thereby improving the data connection conversion efficiency. The existing optical fiber communication module is provided with some functional circuit chips and connection ports inside the shell. When the optical fiber communication module falls during actual use, the functional circuit chips inside the shell are seriously damaged by the impact. The damage to the internal chips will directly lead to the scrapping of the optical fiber communication module, and the protection effect is poor, which shortens the service life. In addition, the optical fiber communication module and the connecting line are usually plug-in in use, and the sealing of the connection is poor, which is easy to seep water into the inside.

[0003] Announcement No. CN220207931U discloses a 1.6T optical fiber communication module, which uses optical fiber to transmit data, converts electrical signals into optical signals, and then transmits them to the receiving end through optical fiber, and then converts the optical signals into electrical signals for data processing. The receiving component in the receiver housing converts the optical signals into electrical signals and processes the data through the communication module. Finally, the processed data will be displayed on the display for users to watch. At the same time, the function of the heat dissipation component is to reduce the temperature and ensure stability and reliability. The function of the fixing component is to fix the position of the receiver housing to prevent movement or shaking during use. The function of the dust cover is to protect the communication module and prevent dust and pollutants from entering the interior and affecting the service life. However, the patent still has the following problems in actual use:

[0004] Although the 1.6T optical fiber communication module is protected by a dust cover, a certain amount of heat will be generated during normal use of the optical fiber communication module. The optical fiber communication module cannot be quickly cooled only by the fan blades and the heat dissipation holes, thereby affecting the service life of the optical fiber communication module. At the same time, when water vapor in the air enters the interior of the receiver housing, it will cause moisture short-circuiting in the optical fiber communication module, and the receiver housing cannot be waterproofed, affecting the service life of the optical fiber communication module.

[0005] An optical fiber communication module with good waterproof performance is proposed to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to provide an optical fiber communication module with good waterproof performance, so as to solve the problem proposed in the above background technology that although the 1.6T optical fiber communication module is protected by setting a dust cover, a certain amount of heat will be generated during the normal use of the optical fiber communication module. The optical fiber communication module cannot be quickly cooled only by fan blades and heat dissipation holes, thereby affecting the service life of the optical fiber communication module. At the same time, when water vapor in the air enters the interior of the receiver housing, it will cause the optical fiber communication module to be damp and short-circuited, and the receiver housing cannot be waterproofed, thereby affecting the service life of the optical fiber communication module.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the optical fiber communication module with good waterproof performance uses a closed slider to realize the preliminary closure of the coupling hole, and uses the elastic force of the sealing spring to make the sealing block engage with the coupling hole, so as to perform secondary closure on the coupling hole, thereby improving the dustproof and waterproof effect of the coupling hole, and preventing water vapor and dust from entering the interior of the optical fiber protection box through the coupling hole, thereby causing the optical fiber communication module to be short-circuited due to moisture, and by sliding the sliding bracket and the waterproof block, when the waterproof block overlaps with the sealing baffle, the internal gap of the heat dissipation frame can be expanded, so as to use the heat dissipation dehumidification fan to perform dehumidification and heat dissipation, and the specific contents are as follows:

[0022] 1. By setting up the protection mechanism, not only can the closed slider be used to achieve the initial closure of the coupling hole, but also the elastic force of the sealing spring can be used to make the sealing block engage and connect with the coupling hole, so as to perform secondary closure of the coupling hole, thereby improving the dustproof and waterproof effect of the coupling hole, and preventing water vapor and dust from entering the interior of the optical fiber protection box through the coupling hole, thereby causing the optical fiber communication module to be short-circuited due to moisture. When using the optical fiber communication module, the closed sliding sleeve is driven to squeeze the closed spring by pulling the connecting ring upwards, and the closed sliding sleeve drives the closed rotating rod and the closed sliding slide to slide upwards. Under the action of the inclined groove on the outer side of the sealing block, the sealing block is separated from the coupling hole, so that the coupling hole can be opened, and the optical module body can be installed into the interior of the heat sink through the coupling hole, and the connection of the optical module body can be achieved. By opening the coupling hole, not only the rapid installation and disassembly of the optical module body can be achieved, but also the connecting line can be connected to the optical module body. When needed When replacing multiple optical module bodies, the connecting bracket and the buffer protection plate are taken out from the inside of the optical fiber protection box through the characteristics of the sliding connection between the installation slide groove and the installation slider, which is convenient for testing, repairing or replacing multiple optical module bodies. The optical module body can be quickly cooled through the first heat dissipation hole inside the heat sink to avoid excessive temperature of the optical module body and affect the normal operation of the optical fiber communication module. When the connecting ring is pulled upward, the connecting ring squeezes the locking bevel groove at the bottom of the locking sliding rod, so that the locking sliding rod squeezes the fixed sliding rod and the fixed spring. When the connecting ring passes over the locking sliding rod, the locking sliding rod is popped out under the elastic force of the fixed spring, thereby supporting the connecting ring and fixing the closed sliding block, so as to facilitate the installation of the optical module body and the connection of the connecting line. By setting the protective spring and the buffer spring, the optical module body can be buffered and protected to avoid damage to the optical module body when the optical fiber protection box falls.

[0023] 2. By setting up the heat dissipation sealing mechanism, not only can the heat dissipation and dehumidification fan inside the sealed box door be used to dissipate heat and dehumidify the inside of the optical fiber protection box, but also the characteristics of the sliding connection between the waterproof block and the sealing baffle can be used to seal the outside of the heat dissipation frame. When the optical fiber communication module is not in use, the sliding bracket and the waterproof block can be loosened to slide on the outside of the heat dissipation frame. When the waterproof block and the sealing baffle are staggered, the outside of the heat dissipation frame can be sealed to achieve the closure of the entire optical fiber communication module, preventing dust and water vapor from entering the interior of the optical fiber communication module and affecting the service life of the optical fiber communication module. When the optical fiber communication module is needed to dissipate heat for the optical fiber communication module, the sliding bracket and the waterproof block can be slid. When the waterproof block overlaps with the sealing baffle, the internal gap of the heat dissipation frame can be expanded, thereby utilizing the heat dissipation and dehumidification fan for dehumidification and heat dissipation. The sealed box door can be opened by the second hinge and the second fixing bolt, so that multiple groups of optical module bodies can be taken out from the inside of the optical fiber protection box, thereby improving the efficiency of replacement and maintenance of the optical module bodies.

[0040] The heat dissipation sealing mechanism 2 includes a sealed box door 201, and second hinges 202 are symmetrically installed on both sides of the bottom of the sealed box door 201. The two sealed box doors 201 are rotatably connected to the optical fiber protection box 101 through the second hinges 202. The top of the sealed box door 201 is symmetrically threaded with a second fixing bolt 203. The sealed box door 201 is fixedly connected to the optical fiber protection box 101 through the second fixing bolt 203.

The outer side of the heat dissipation frame 205 is fixedly installed. A number of sealing baffles 208 are fixedly installed, and the heat dissipation and dehumidification fan 207 inside the sealed box door 201 is used to dissipate heat and dehumidify the inside of the optical fiber protection box 101. At the same time, the waterproof block 210 and the sealing baffle 208 are slidably connected to seal the outside of the heat dissipation frame 205. When the optical fiber communication module is not in use, the sliding bracket 209 and the waterproof block 210 are allowed to slide on the outside of the heat dissipation frame 205 by loosening the locking threaded rod 211. When the waterproof block 210 and the sealing baffle 208 are staggered, the outside of the heat dissipation frame 205 can be closed to achieve the closure of the entire optical fiber communication module, thereby preventing dust and water vapor from entering the interior of the optical fiber communication module and affecting the service life of the optical fiber communication module.

The interiors of the two sliding brackets 209 are both threadedly connected with locking threaded rods 211, and the sliding brackets 209 are fitted and connected to the heat dissipation frame 205 through the locking threaded rods 211. When the optical fiber communication module is needed to dissipate heat for the optical fiber communication module, the sliding brackets 209 and the waterproof blocks 210 can be slid. When the waterproof blocks 210 overlap with the sealing baffle 208, the internal gap of the heat dissipation frame 205 can be expanded, so that the heat dissipation and dehumidification fan 207 can be used for dehumidification and heat dissipation. The sealed box door 201 can be opened by the second hinge 202 and the second fixing bolt 203, so that multiple groups of optical module bodies 127 can be taken out from the interior of the optical fiber protection box 101, thereby improving the efficiency of replacement and maintenance of the optical module bodies 127.

[0042] Working principle: Before using this waterproof fiber optic communication module, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Fig.11As shown, first, the coupling hole 104 is initially closed by using the closing slider 111, and at the same time, the sealing block 113 is engaged with the coupling hole 104 by using the elastic force of the sealing spring 112, so that the coupling hole 104 is secondary closed, thereby improving the dustproof and waterproof effect of the coupling hole 104, and preventing water vapor and dust from entering the interior of the optical fiber protection box 101 through the coupling hole 104, thereby causing the optical fiber communication module to be short-circuited due to moisture. When using the optical fiber communication module, the closing sliding sleeve 107 is driven to squeeze the closing spring 107 by pulling the connecting ring 109 upward. 08, and at the same time, the closed sliding sleeve 107 drives the closed rotating rod 110 and the closed sliding block 111 to slide upward, and under the action of the inclined groove on the outer side of the sealing block 113, the sealing block 113 is separated from the coupling hole 104, so that the coupling hole 104 can be opened, and the optical module body 127 can be installed to the inside of the heat sink 125 through the coupling hole 104, and the connection of the optical module body 127 can be realized. By opening the coupling hole 104, not only can the optical module body 127 be quickly installed and disassembled, but the connecting line can also be connected to the optical module body 127.

[0043] Secondly, when it is necessary to replace multiple optical module bodies 127, the connecting bracket 116 and the buffer protection plate 122 are taken out from the inside of the optical fiber protection box 101 through the characteristics of the sliding connection between the installation groove 114 and the installation slider 115, so as to facilitate the inspection, maintenance or replacement of multiple optical module bodies 127. The optical module body 127 can be quickly cooled through the first heat dissipation hole 126 inside the heat sink 125 to prevent the optical module body 127 from overheating and affecting the normal operation of the optical fiber communication module. When the connecting ring 109 is pulled upward, the connecting ring 109 squeezes the locking groove 134 at the bottom of the locking sliding rod 133, so that the locking sliding rod 133 squeezes the fixed sliding rod 132 and the fixed spring 131. When the connecting ring 109 passes over the locking sliding rod 133, the locking sliding rod 133 is popped out under the elastic force of the fixed spring 131, thereby supporting the connecting ring 109 and fixing the closing slider 111 and the sealing block 113, so as to facilitate the installation of the optical module body 127 and the connection of the connecting wire.

[0044] Finally, the heat dissipation and dehumidification fan 207 inside the sealed box door 201 is used to dissipate heat and dehumidify the inside of the optical fiber protection box 101. At the same time, the waterproof block 210 and the sealing baffle 208 are slidably connected to seal the outside of the heat dissipation frame 205. When the optical fiber communication module is not in use, the sliding bracket 209 and the waterproof block 210 are loosened by the locking threaded rod 211 to slide on the outside of the heat dissipation frame 205. When the waterproof block 210 and the sealing baffle 208 are staggered, the outside of the heat dissipation frame 205 can be sealed to achieve the closure of the entire optical fiber communication module and prevent dust and water vapor from entering. To the interior of the optical fiber communication module, affecting the service life of the optical fiber communication module. When the optical fiber communication module needs to dissipate heat, the sliding bracket 209 and the waterproof block 210 can be slid. When the waterproof block 210 overlaps with the sealing baffle 208, the internal gap of the heat dissipation frame 205 can be expanded, so that the heat dissipation and dehumidification fan 207 can be used for dehumidification and heat dissipation. The sealed box door 201 can be opened by the second hinge 202 and the second fixing bolt 203, so that multiple groups of optical module bodies 127 can be taken out from the interior of the optical fiber protection box 101, thereby improving the efficiency of replacement and maintenance of the optical module bodies 127.
