Description

Technical Field

[0001] This utility model relates to the field of optical module protection technology, and in particular to an optical module protection device. Background Technology

[0002] As the core optoelectronic conversion device in optical fiber communication systems, optical modules are characterized by their precise structure, high cost, and sensitivity to the environment. During storage, transportation, and on-site maintenance, optical modules are often in an uninstalled standby state, making them highly susceptible to external mechanical shocks, dust contamination, electrostatic discharge, and other effects. Especially in construction sites or data center operations and maintenance, optical modules are often damaged by accidental drops, resulting in shell deformation, internal optical path misalignment, or damage to the gold fingers, causing performance degradation or even permanent failure, which seriously affects the stability of the communication system and maintenance costs.

[0003] Currently, most common optical module protection devices on the market use simple plastic shells or anti-static bags for packaging. Although they have a certain dustproof and pressure-resistant capabilities, their protection level is low and they are difficult to effectively resist drop impacts. Secondly, although some products are equipped with openable and closable sealing covers to improve dustproof performance, in actual use, after the user opens the sealing cover, the optical module is still completely inside the shell and it is difficult to remove it. This operation is not only laborious and inconvenient, but also makes it very easy for fingers to touch the optical port at the front of the optical module or the gold fingers at the bottom, which brings the risk of electrostatic discharge or grease contamination. This can cause signal attenuation at best, and laser burnout or circuit damage at worst. Utility Model Content

[0004] This utility model provides an optical module protection device, including a protective shell, which is sleeved on the outside of the optical module. One end of the protective shell is open and flip covers are rotatably provided on both sides. The flip covers are flipped by a pushing mechanism. At the same time, an auxiliary strip is fixedly provided on the optical module, and a plug is inserted into the auxiliary strip. During the process of the pushing mechanism sliding on the outside of the protective shell to drive the flip covers to flip, the plug pushes the optical module to move out of the protective shell.

[0005] Preferably, the two flaps are symmetrically hinged to the two sides of the opening end of the protective shell via a pivot. The free end of the pivot is fixedly connected to a gear. The two gears are parallel to each other and in the same plane. The pushing mechanism includes a slidable sleeve on the outside of the protective shell. A rack is fixedly provided on one side of the sleeve. Both ends of the rack are provided with teeth. The teeth at both ends mesh with the two gears respectively. When the rack slides, it drives the two gears to rotate synchronously, thereby driving the two flaps to flip outward synchronously. The gears and rack are protected by a side plate provided on the outside of the protective shell.

[0006] Preferably, the inner edge of the flip cover is provided with a sealing strip. When the two flip covers are closed, the sealing strips on both sides fit together to form a dustproof and sealing structure.

[0007] Preferably, a limiting rod is rotatably provided on one side of the ferrule, and one end of the limiting rod is threadedly connected to a threaded groove on one side of the protective shell to limit the sliding stroke of the rack.

[0008] Preferably, the top of the protective shell has a groove extending along the length direction, the insert block is slidably disposed in the groove, and partially extends out of the groove.

[0009] Preferably, the insert is engaged with a slot on an auxiliary strip fixed to the optical module, and a protrusion is provided on the upper side of the sleeve, which is engaged with a groove on one side of the insert.

[0010] Preferably, the inner wall of the protective shell is fitted with an elastic liner made of silicone to cushion external impacts and prevent scratches on the surface of the optical module.

[0011] Preferably, two sets of positioning rods arranged in a figure-eight shape are symmetrically hinged on both sides of the inner cavity of the protective shell. The free end of the positioning rod has an arc-shaped structure for fitting the outer shell of the optical module. The middle part of the positioning rod is connected to the inner wall of the protective shell through a tension spring to provide inward clamping force.

[0012] Preferably, protective corner sleeves are fitted at the corners of the protective shell and the flip cover. The protective corner sleeves are made of flexible material and have several airbag strips on their surface to absorb the impact energy of a fall.

[0013] Preferably, the top of the protective shell is provided with a slot, and the bottom is provided with a plate that cooperates with adjacent devices. Multiple protective shells can be stacked and fixed by the insertion and cooperation of the plate and the slot.

[0014] The optical module protection device provided in this embodiment of the utility model, compared with the prior art: 1. This utility model innovatively links the flip-cover opening action with the optical module ejection action. When the user slides the sliding sleeve to drive the rack, the two flip covers can be opened automatically at the same time, and the insertion block can push the optical module. When the flip covers are flipped outward, the protrusion on the sleeve pushes the insertion block to slide along the slide groove, causing the optical module to extend outward from the opening end of the protective shell by a certain length. This allows the operator to easily grab the optical module without inserting their fingers into the protective shell. This design effectively avoids direct contact between fingers and the optical port, gold fingers, and other precision parts of the optical module, preventing damage to the device caused by static electricity, grease contamination, or accidental contact. It improves the safety and convenience of use, especially in scenarios with frequent replacement or inspection, reducing operational risks and improving maintenance efficiency.

[0015] 2. This utility model achieves comprehensive physical protection for the optical module by setting up a protective shell with a flip cover, an elastic inner liner, a positioning rod, and protective corner sleeves. The elastic silicone inner liner attached to the outer wall of the protective shell can effectively buffer external impacts and prevent the optical module from being damaged during drops or squeezing. The positioning rod arranged in a figure-eight shape forms a flexible clamp on the optical module shell under the action of a tension spring, preventing it from shaking and wearing inside the shell. When the flip cover is closed, the inner sealing strips fit together to form an effective dustproof seal, preventing dust and foreign objects from entering the optical port and causing pollution or damage. The protective corner sleeves with airbag strips set at the corners further enhance the impact resistance and improve the overall durability of the device. Attached Figure Description

[0019] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0020] Please refer to Figures 1-8 This utility model provides an optical module protection device, including a protective shell 1. The protective shell 1 is a long strip structure, which is sleeved on the outside of the optical module. One end of the protective shell has an opening for inserting and removing the optical module.

[0021] like Figure 6 As shown, the inner wall of the protective shell 1 is covered with an elastic silicone liner 7, which can effectively buffer external impacts and prevent the optical module from being damaged during drops or squeezing. At the same time, two sets of positioning rods 19 arranged in a figure-eight shape are symmetrically hinged on both sides of the inner cavity of the protective shell 1. The free end of the positioning rod 19 has an arc-shaped structure, which can fit the contour of the optical module shell. The middle part of the positioning rod 19 is connected to the inner wall of the protective shell 1 through a tension spring 20. Under the elastic force of the tension spring 20, the two sets of positioning rods 19 form a flexible clamp for the optical module, preventing it from shaking and wearing inside the shell and improving the fixation stability.

[0022] On the two side walls of the opening end of the protective shell 1, there are two hinged flip covers 8 that can be flipped open and closed. The two flip covers 8 are installed on the protective shell 1 through a rotating shaft. The free end of the rotating shaft extends to the outside of the protective shell 1 and is fixedly connected to a gear 10. The two gears 10 are parallel to each other and are in the same plane.

[0023] like Figure 8 As shown, a pushing mechanism is provided on the outside of the protective shell 1. The pushing mechanism includes a sliding sleeve 12. The sleeve 12 can slide along the length of the protective shell 1. A rack 11 is fixed on one side of the sleeve 12. Both ends of the rack 11 are provided with teeth, which mesh with two gears 10 respectively.

[0024] When the sleeve 12 slides, it drives the rack 11 to move, thereby driving the two gears 10 to rotate synchronously, so that the two flip covers 8 can flip outward or close inward synchronously. In order to prevent the gears 10 and rack 11 from being exposed and damaged, the outer side of the protective shell 1 is also provided with a side plate 18 to protect the gears 10 and rack 11.

[0025] Furthermore, the inner edge of the flip cover 8 is provided with a sealing strip 9. When the two flip covers 8 are closed, the sealing strips 9 on both sides fit together to form an effective dustproof sealing structure, preventing dust and foreign objects from entering the interior of the protective shell 1 and avoiding contamination of the optical port of the optical module.

[0026] like Figure 5As shown, to facilitate the easy access of the optical module, an auxiliary strip 15 is fixedly connected to the optical module. The auxiliary strip 15 has a slot 16, and the plug 17 is inserted into the slot 16 to achieve a detachable connection. The top of the protective shell 1 has a sliding groove 6 extending along the length direction. The plug 17 is slidably disposed in the sliding groove 6 and partially extends out of the outside of the sliding groove 6. One end of the sliding groove 6 extends to one side of the protective shell 1 and is in an open state, so that the plug 17 can slide out from the sliding groove 6, which is convenient for the optical module to be taken out. In addition, when the flip cover 8 is flipped up, there is a certain gap between it and the protective shell 1, which facilitates the sliding of the plug 17.

[0027] The upper side of the sleeve 12 is provided with a protrusion 14, which is engaged with the groove on one side of the insert 17. When the sleeve 12 slides, the protrusion 14 pushes the insert 17 to move along the slide groove 6, thereby driving the optical module to slide outward from the opening end of the protective shell 1 a certain distance. In the natural state, the protrusion 14 and the insert 17 maintain a certain distance. When the sleeve 12 pushes the rack 11 to slide, the flip cover 8 is opened first, and the protrusion 14 and the insert 17 are engaged to push the optical module to move outward, avoiding collision between the optical module and the flip cover 8.

[0028] To limit the movement of the flip cover 8, a limiting rod 13 is rotatably provided on one side of the sleeve 12. One end of the limiting rod 13 can be threaded into the threaded groove 5 opened on the side wall of the protective shell 1. By screwing in the limiting rod 13, the sliding stroke of the sleeve 12 can be limited, ensuring that the flip cover 8 remains stable when sealed.

[0029] In addition, to enhance the overall impact resistance, protective corner sleeves 2 made of flexible material are fitted at the corners of the protective shell 1 and the flip cover 8. The surface of the sleeves is provided with several airbag strips, which can absorb impact energy when the device is dropped, effectively protecting the internal optical module.

[0030] To facilitate centralized management and storage, the top of the protective shell 1 is provided with a slot 3 and the bottom is provided with a plate 4. Multiple protective shells 1 can be stably stacked by inserting and cooperating with the plate 4 of the upper device and the slot 3 of the lower device, saving space and improving operation and maintenance efficiency.

[0031] In summary, the working principle of the optical module protection device of this utility model embodiment is as follows: When it is necessary to remove the optical module, the user pushes the sleeve 12 to slide along the outside of the protective shell 1, so that the sleeve 12 drives the rack 11 to move, driving the two gears 10 to rotate synchronously, and the two flip covers 8 to flip outward synchronously. During the process, the protrusion 14 on the sleeve 12 pushes the insertion block 17 to slide along the slide groove 6. The insertion block 17 drives the optical module to extend outward from the opening end of the protective shell 1 by a certain length. The operator can directly grab the partially extended optical module without inserting fingers into the shell, avoiding contact with the optical port or gold fingers, and preventing damage from static electricity, contamination or accidental contact.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
