Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of digital optical modules, and more specifically, to a digital optical module with a waterproof structure. Background Art
[0002] As a key component in modern communication systems, the digital optical module undertakes the important task of optoelectronic signal conversion and is widely used in fields such as data centers, communication networks, enterprise networks, and fiber access networks. By realizing the mutual conversion of optical signals and electrical signals, it ensures high-speed and high-capacity data transmission. In practical applications, one end of the digital optical module extends deep into the device and is connected to core components such as circuit boards, while the other end is exposed outside for fiber optic docking to achieve long-distance communication.
[0003] However, this design has significant hidden dangers in a humid environment. Since the fiber optic docking port exposed outside often lacks a sufficient waterproof structure, when the environmental humidity is high, water vapor easily penetrates into the digital optical module through this port. Over time, the internal water accumulation may cause a short circuit in the circuit, seriously affecting the normal operation of the digital optical module and even causing equipment damage. Summary of the Utility Model
[0004] To make up for the above deficiencies, the utility model provides a digital optical module with a waterproof structure to solve the above problems.
[0005] The utility model is implemented as follows:
[0006] A digital optical module with a waterproof structure includes a digital optical module body and a waterproof kit. One end of the digital optical module body has a docking port for external fiber optic docking. A connector is provided on the bottom wall of the docking port. Two clamping mechanisms are symmetrically arranged along the center on the side wall of the docking port. The waterproof kit includes an insertion end and a limiting end at its end. Slots are provided on both sides of the insertion end, and a sealing groove is opened at the end of the insertion end. A first sealing ring is arranged along the edge of the sealing groove. An active sealing mechanism is arranged inside the sealing groove. The waterproof kit is inserted and removed in the docking port. After insertion, the first sealing ring abuts against the bottom wall of the docking port, the connector is inserted into the sealing groove, and the active sealing mechanism abuts against the end of the connector. A cable tie is arranged between the digital optical module body and the waterproof kit.
[0007] In an embodiment of the present utility model, the clamping mechanism includes a side groove formed on the inner sidewall of the docking port. A clamping spring is arranged on the inner sidewall of the side groove near the outlet of the docking port. The clamping spring has a bent portion, and the bent portion is located outside the notch of the side groove. When the insertion end of the waterproof kit is inserted into the docking port, the sidewall of the insertion end presses the clamping spring, causing it to be squeezed towards the inside of the side groove. After being completely inserted, the clamping spring is embedded in the clamping groove.
[0008] In an embodiment of the present utility model, the movable sealing mechanism includes a movable plate. A contact head is arranged at the center of one side of the movable plate, and a guide rod is designed at the center of the other side. A guide groove is formed at the center of the bottom wall of the sealing groove, and the guide rod is inserted into the guide groove. A plurality of contact springs are connected between the movable plate and the sealing groove.
[0009] In an embodiment of the present utility model, a limiting flange is arranged on the inner sidewall of the guide groove near the outlet, and a limiting piece is arranged at the end of the guide rod. When the movable plate is not affected by an external force, the limiting piece abuts against the limiting flange.
[0010] In an embodiment of the present utility model, a second sealing ring is arranged on the side of the movable plate where the contact head is located. When the waterproof kit is inserted into the docking port, the second sealing ring abuts against the end of the connecting head.
[0011] In an embodiment of the present utility model, a rubber cushion layer covers the outside of the contact head. When the waterproof kit is inserted into the docking port, the contact head abuts against the opening of the connecting head where the gold fingers are located.
[0012] In an embodiment of the present utility model, a first connecting portion is arranged at the outer edge of the docking port, and a second connecting portion is arranged at the edge of the limiting end away from the insertion end. The binding band is arranged between the first connecting portion and the second connecting portion.
[0013] In an embodiment of the present utility model, the binding band is an elastic binding band.
[0014] The beneficial effects of the present utility model are as follows: The design of the clamping mechanism realizes the quick plugging and unplugging function of the waterproof kit. This design not only simplifies the operation process but also improves the usage efficiency, enabling users to complete the disassembly and assembly of the waterproof kit in a short time. The optical module adopts a multi-layer sealing structure including a first sealing ring, a second sealing ring, and a movable sealing mechanism. These sealing layers cooperate with each other to form a waterproof barrier, effectively preventing water vapor from seeping into the module through tiny gaps, thereby avoiding short-circuit problems caused by internal water accumulation. Using an elastic band as the connecting component between the waterproof kit and the digital optical module body not only plays a role in preventing loss, but its elastic elongation characteristic also meets the requirements of waterproof kits of different sizes and shapes, enhancing the adaptability of the product.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.
[0022] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the claimed present utility model, but merely represents selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.
[0023] As Figures 1-3 shown, the present utility model provides a digital optical module with a waterproof structure, which includes a digital optical module body 10 and a waterproof kit 20. One end of the digital optical module body 10 has a docking port 11 for external optical fiber docking. A connector 13 is provided on the bottom wall of the docking port 11. Two clamping mechanisms 12 are symmetrically arranged along the center on the side wall of the docking port 11. The waterproof kit 20 includes an insertion end 21 and a limiting end 22 at its end. Clamping grooves 2101 are provided on both sides of the insertion end 21. The cooperation between the clamping mechanism 12 and the clamping grooves 2101 enables the quick insertion and extraction of the waterproof kit 20, increasing its convenience. A sealing groove 2102 is opened at the end of the insertion end 21. A first sealing ring 24 is arranged along the edge of the sealing groove 2102. An active sealing mechanism 25 is arranged inside the sealing groove 2102. The waterproof kit 20 is inserted and extracted in the docking port 11. After insertion, the first sealing ring 24 abuts against the bottom wall of the docking port 11. The connector 13 is inserted into the sealing groove 2102, and the active sealing mechanism 25 abuts against the end of the connector 13. The first sealing ring 24 and the active sealing mechanism 25 together provide a double-layer sealing protection effect, further ensuring that water vapor cannot enter. A cable tie 30 is arranged between the digital optical module body 10 and the waterproof kit 20. The unused docking port 11 is sealed with the waterproof kit 20 to ensure that external water vapor cannot enter the inside of the digital optical module body 10 from the docking port 11, causing a short circuit in the circuit.
[0024] As Figures 1-2As shown, the clamping mechanism 12 includes a side groove 1201 opened on the inner wall of the docking port 11, and a clamping spring 1202 is arranged on the inner wall of the side groove 1201 near the outlet of the docking port 11. The clamping spring 1202 has a bending portion, and the bending portion is located outside the notch of the side groove 1201. When the insertion end 21 of the waterproof kit 20 is inserted into the docking port 11, the side wall of the insertion end 21 squeezes the clamping spring 1202, so that it is squeezed into the inside of the side groove 1201. After it is fully inserted, the clamping spring 1202 is embedded in the clamping groove 2101. When it needs to be pulled out, pinch the limit end 22 and pull it outward with force. At this time, the oblique mouth at the clamping groove 2101 resists the clamping spring 1202, so that it is squeezed into the inside of the side groove 1201, thereby completing the removal of the waterproof kit 20. The clamping mechanism 12 realizes the quick plug-in and pull-out function of the waterproof kit 20, which increases the convenience of use.
[0025] like Figures 3-4 As shown, the movable sealing mechanism 25 includes a movable plate 2501, a contact head 2502 is arranged at the center of one side of the movable plate 2501, a guide rod 2503 is designed at the center of the other side, a guide groove 2505 is opened at the center of the bottom wall of the sealing groove 2102, the guide rod 2503 is inserted into the guide groove 2505, and a plurality of contact springs 2506 are connected between the movable plate 2501 and the sealing groove 2102.
[0026] Furthermore, a limiting flange is provided on the inner wall of the guide groove 2505 near the exit, and a limiting piece 2504 is provided at the end of the guide rod 2503. When the movable plate 2501 is not subjected to external force, the limiting piece 2504 contacts the limiting flange.
[0027] Furthermore, a second sealing ring 2507 is provided on one side of the abutment head 2502 on the movable plate 2501 . When the waterproof kit 20 is inserted into the docking port 11 , the second sealing ring 2507 abuts against the end of the connector 13 .
[0028] Furthermore, the outer side of the abutment head 2502 is covered with a rubber cushion layer, and the waterproof kit 20 is inserted into the docking port 11 , and the abutment head 2502 abuts against the opening of the gold finger at the end of the connector 13 .
[0029] As described above, after the waterproof kit 20 is inserted into the docking port 11, the first sealing ring 24 first contacts the bottom end of the docking port 11 to form a first layer of seal, and then the second sealing ring 2507 contacts the end of the connector 13 to form a second layer of seal, and finally the contact head 2502 contacts the opening at one end of the connector 13 with a gold finger to form a third layer of seal. The combination of the three effectively prevents the intrusion of water vapor and ensures its stable operation in various environments.
[0030] In this embodiment, a first connection portion 14 is provided at the outer edge of the docking port 11, a second connection portion 23 is provided at the edge of the side of the limiting end 22 away from the insertion end 21, and a strap 30 is provided between the first connection portion 14 and the second connection portion 23. The strap 30 prevents the waterproof kit 20 from being lost during use.
[0031] As a preferred embodiment, the strap 30 is an elastic strap 30. The elastic strap 30 can be used in a shorter specification. Its elastic stretching property can not only meet the normal plugging and unplugging of the waterproof kit 20, but also avoid the phenomenon of interlaced knots of ordinary straps 30 after being too long, which not only affects the appearance but also makes it inconvenient to use.
[0032] Specifically, the working principle of the digital optical module with a waterproof structure is as follows: for the unused docking port 11, the waterproof kit 20 at the location is inserted into the docking port 11. During this process, the insertion end 21 squeezes the retaining spring 1202 until it is embedded in the card slot 2101. At this point, the first sealing ring 24 is in contact with the docking port 11, the second sealing ring 2507 is in contact with the end of the connector 13, and the movable plate 2501 is squeezed toward the inner side of the sealing slot 2102. The elastic force of the retaining spring 2506 makes the connection between the second sealing ring 2507 and the connector 13 tighter. At the same time, the rubber pad layer on the contact head 2502 is soft and elastic, which can form a sealed contact with the opening with a gold finger on the end of the connector 13. The multi-layer structure can enhance the waterproof effect of the waterproof kit 20 and the effect of protecting the docking port 11. Through the above structure, the problem of lack of waterproof structure of the optical fiber docking port 11 exposed to the outside in the prior art is solved, so that in an environment with high humidity, water vapor can easily penetrate into the digital optical module through the port, causing water accumulation inside and even a circuit short circuit, seriously affecting the normal operation of the digital optical module, and even causing damage to the equipment.
[0033] The utility model is further described above with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the utility model. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the utility model.
