Description

Technical Field

[0001] This utility model relates to the field of optical module technology, specifically to an optical module structure that prevents misinsertion. Background Technology

[0002] In modern information transmission scenarios such as data centers and communication base stations, optical modules are the core components for realizing photoelectric signal conversion and transmission. Their connection with external devices directly affects the stability of signal transmission and the operating efficiency of the equipment. Since the installation, maintenance and replacement of optical modules are frequent in these scenarios, and there are often multiple optical modules densely arranged, operators are prone to deviations in the insertion direction due to visual errors or operational negligence during the insertion and removal process. Therefore, optical module structures with anti-misinsertion functions have become a key requirement for ensuring reliable equipment operation and reducing maintenance costs.

[0003] Existing optical module structures typically include a housing, an optical module body housed within the housing, and a connector for interfacing with external devices. While some optical modules incorporate simple anti-misinsertion structures, such as a single protrusion or groove, the overall design is relatively simplistic. Specifically, existing anti-misinsertion structures for optical modules are mostly single limiting protrusions, lacking multi-directional collaborative protection and guidance designs. This not only fails to effectively prevent misalignment during insertion, making it easy for operators to force misinsertion, resulting in collision damage to the housing, connector, and external device interface, but also fails to accurately guide the optical module to quickly align with the external device, reducing insertion speed. The existing optical module plug-in connection structure relies heavily on simple insertion and removal friction for fixation, lacking a stable elastic clamping mechanism. After plugging in, it is prone to loosening due to equipment vibration, long-term wear and tear, etc., affecting the continuity of signal transmission. In addition, the rotatable abutment parts of some optical modules have problems with insecure installation and rotation jamming, and lack a symmetrical layout design, resulting in unstable abutment and reset actions. This further weakens the anti-misinsertion effect and shortens the service life of the components, failing to meet the comprehensive requirements of convenient operation, connection stability and protection reliability in high-frequency plugging and unplugging scenarios. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an optical module structure that prevents misinsertion, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a structure for preventing misinsertion of an optical module, comprising a first housing and a second housing, the second housing being snapped onto and covering the outside of the first housing, an optical module body being disposed within a cavity formed by the first housing and the second housing, a handle being integrally formed on the outer side wall of the first housing, an external port being provided through the end of the first housing facing the handle, and an anti-misinsertion plug being provided on the inner wall of the external port; The second housing has a connecting frame fixedly connected to one end away from the external port. The connecting frame contains a plug-in block adapted to the external device. The end of the plug-in block away from the connecting frame is used to plug into the external device. When plugged in correctly, the connecting frame and the plug-in block form a surface contact plug-in fit. Both the first housing and the second housing are provided with an anti-misinsertion component; Preferably, the anti-misinsertion component includes a first protrusion integrally formed on the outer side wall of the front end of the second housing, and the first protrusion is trapezoidal in shape; Preferably, the anti-misinsertion component further includes a second protrusion integrally formed on the side of the first housing, the second protrusion being perpendicularly disposed to the outer side wall of the first housing, for guiding the first housing and the second housing to be synchronously and correctly aligned and inserted with the external device; Preferably, the anti-misinsertion assembly further includes a mounting groove formed on the outer side wall of the first housing, and an abutment plate is rotatably connected in the mounting groove via a rotating shaft; Two mounting slots are provided, and the two mounting slots are symmetrically opened on both sides of the outside of the first housing. Preferably, when the first housing is correctly inserted into the external device, the abutment plate is squeezed by the external device and rotates along the pivot axis into the mounting groove, eventually fitting against the bottom wall of the mounting groove and retracting into a retracted state. Preferably, one end of the abutment plate has a mounting hole, and a torsion spring is embedded in the mounting hole; One end of the torsion spring is fixedly connected to the abutment plate, and the other end is fixedly connected to the wall of the mounting groove, so as to provide an elastic force to reset the abutment plate and press it against the inner wall of the external equipment, thereby achieving a stable connection between the abutment plate and the external equipment. Preferably, the first protrusion, the second protrusion, and the abutment plate are evenly distributed along the circumference of the first shell, together forming a triple anti-misinsertion limiting structure.

[0006] In summary, the present invention has the following main advantages: 1. This utility model uses a connecting plate and an embedded torsion spring. After insertion, the elastic force of the torsion spring can drive the connecting plate to press tightly against the inner wall of the external device. At the same time, the connecting frame and the external device form a surface contact insertion fit. The dual structure ensures the stability of the connection and avoids loosening during use. When pulling out, the torsion spring can drive the connecting plate to automatically reset and disengage from the pressing state, making the insertion and removal process smooth and effortless, taking into account both reliability and ease of operation. 2. This utility model uses a trapezoidal first protrusion to prevent mis-insertion, and a vertically arranged second protrusion to provide insertion guidance. Combined with the triple limiting structure formed by the first and second protrusions evenly distributed along the circumference of the shell and the abutment plate, it can not only achieve precise guidance of the insertion direction, but also effectively prevent forced insertion in the deviated direction. From the structural design, it directly reduces the risk of damage to the equipment caused by mis-insertion and improves the accuracy of operation. Attached Figure Description

[0009] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0010] The embodiments of this utility model will be described below based on its overall structure.

[0011] Example Please see Figures 1-5This utility model provides a technical solution: an anti-misinsertion optical module structure, including a first housing 11 and a second housing 12. The second housing 12 is snapped onto the outside of the first housing 11 by two side snaps. The optical module body 21 is disposed in the sealed cavity formed by the first housing 11 and the second housing 12. A handle 13 is integrally formed on the outer side wall of the first housing 11. A dustproof and sealed external port 22 is provided through the end of the first housing 11 facing the handle 13. The inner wall of the external port 22 is provided with an anti-misinsertion plug 221 to improve the anti-misinsertion function. The snap-fit ​​covering structure of the first housing 11 and the second housing 12 can form a stable protection for the optical module body 21. The handle 13 is convenient for operators to hold and insert. The dustproof and sealed external port 22 ensures the signal transmission stability between the optical module body 21 and external devices, while improving the dustproof and waterproof performance of the device, enhancing its practicality and ease of operation. The end of the second housing 12 furthest from the external port 22 is fixedly connected to a connecting frame 23 by screws. Inside the connecting frame 23, a plug-in block 24 adapted to the external device is integrally molded by injection molding. The end of the plug-in block 24 furthest from the connecting frame 23 is provided with a guide chamfer for plugging into the external device. When correctly plugged in, the connecting frame 23 and the plug-in block 24 form a surface contact plug-in fit. The screw-fixed connection structure between the connecting frame 23 and the second housing 12 ensures the installation stability of the plug-in block 24. The guide chamfer design of the plug-in block 24 facilitates initial alignment. Its adaptation design to the external device and the surface contact fit between the connecting frame 23 and the plug-in block 24 increase the plug-in contact area, improve the connection reliability, and avoid the problem of poor contact during plugging. At the same time, the integrally molded plug-in block 24 has higher structural strength and is not easily deformed or damaged. Anti-misinsertion components 3 are correspondingly provided on the first housing 11 and the second housing 12 along the insertion direction. The corresponding distribution of anti-misinsertion components 3 on the first housing 11 and the second housing 12 can achieve the anti-misinsertion function from multiple directions, laying a structural foundation for the subsequent cooperation of various anti-misinsertion components, effectively reducing the probability of misinsertion, avoiding collisions or wear to the first housing 11, the second housing 12 and external devices due to misinsertion, and protecting each component from damage. Furthermore, the anti-misinsertion component 3 includes a first protrusion 31 integrally formed on the outer side wall of the front end of the second housing 12. The first protrusion 31 is trapezoidal in shape and its length is adapted to the width of the front end of the second housing 12. The trapezoidal first protrusion 31 integrally formed on the second housing 12 has high structural strength and is not easy to fall off. The inclined surface of the trapezoidal structure can form an effective physical barrier when the insertion direction is deviated, preventing the operator from forcibly inserting it. At the same time, its length design adapted to the width of the second housing 12 expands the anti-misinsertion blocking range, further improving the anti-misinsertion protection performance of the device and protecting the second housing 12 and the external equipment interface from damage. Furthermore, the anti-misinsertion component 3 also includes a second protrusion 32 integrally formed on the side of the first housing 11. The second protrusion 32 is perpendicular to the outer wall of the first housing 11 and its extension length is adapted to the insertion depth of the insertion block 24. It is used to guide the first housing 11 and the second housing 12 to be correctly aligned and inserted with the external device at the same time. The second protrusion 32, which is perpendicular to the first housing 11 and whose extension length is adapted, can accurately fit the guide groove of the external device, guide the first housing 11 and the second housing 12 to be aligned with the external device at the same time, ensure the accurate insertion direction, reduce the alignment deviation during the insertion process, and improve the efficiency and accuracy of the insertion operation. The integrally formed structure also ensures the guiding stability of the second protrusion 32 and avoids breakage or deformation during the guiding process. Furthermore, the anti-misinsertion component 3 also includes a mounting groove 33 opened on the outer wall of the first housing 11. The depth of the mounting groove 33 is adapted to the thickness of the abutment plate 34. The abutment plate 34 is rotatably connected in the mounting groove 33 through a stainless steel rotating shaft. There are two mounting grooves 33, which are symmetrically opened on both sides of the outer side of the first housing 11. The mounting grooves 33 symmetrically opened on both sides of the outer side of the first housing 11, together with the abutment plate 34 adapted to the groove depth and the rotating connection structure of the stainless steel rotating shaft, not only ensure the flexibility of the rotation of the abutment plate 34, but also avoid jamming during the rotation. The symmetrical arrangement makes the abutment plate 34 bear force evenly, improves the stability of subsequent abutment and reset actions, and provides reliable structural support for anti-misinsertion and stable connection. The stainless steel rotating shaft also enhances the wear resistance and service life of the rotating connection. Furthermore, when the first housing 11 is correctly inserted into the external device, the abutment plate 34 is squeezed by the inner wall of the external device and rotates along the pivot axis into the mounting groove 33, eventually fitting against the bottom wall of the mounting groove 33 in a retracted state. It can be completely retracted into the mounting groove 33 when correctly inserted, avoiding any obstruction to the insertion process and ensuring smooth insertion. At the same time, the retracted method of fitting against the bottom wall of the mounting groove 33 can protect the abutment plate 34 from friction damage during the insertion process, extend its service life, and ensure the continued effectiveness of subsequent anti-misinsertion and stable connection functions. Furthermore, one end of the abutment plate 34 is provided with a mounting hole, in which a stainless steel torsion spring 35 is embedded. One end of the torsion spring 35 is welded and fixed to the abutment plate 34, and the other end is welded and fixed to the groove wall of the mounting groove 33, so as to provide an elastic force to reset the abutment plate 34 and press it against the inner wall of the external device, thereby realizing a stable connection between the abutment plate 34 and the external device. The stainless steel torsion spring 35 in the mounting hole of the abutment plate 34 has high strength and long-lasting elasticity. The welding and fixing method at both ends ensures the connection is firm and can provide a stable and long-lasting elastic force, ensuring that the abutment plate 34 is accurately reset and presses tightly against the inner wall of the external device, effectively improving the connection stability between the abutment plate 34 and the external device, avoiding loosening due to vibration and other factors during use, and preventing signal transmission interruption. Furthermore, the first protrusion 31, the second protrusion 32, and the abutment plate 34 are evenly distributed along the circumference of the first housing 11, forming a triple anti-misinsertion limiting structure. The triple anti-misinsertion limiting structure, with the first protrusion 31, the second protrusion 32, and the abutment plate 34 evenly distributed along the circumference of the first housing 11, can form all-round anti-misinsertion protection and limiting guidance from different directions, further improving the accuracy and reliability of anti-misinsertion. At the same time, the collaborative work of multiple structures reduces the risk of failure of the anti-misinsertion function due to the failure of a single component, ensuring the anti-misinsertion effect of the device during long-term use and improving the overall safety of use.

[0012] The working principle of this utility model is as follows: The operator holds the handle 13 on the outer wall of the first housing 11 and aligns the connecting frame 23 of the second housing 12 away from the external port 22 with the plug interface of the external device. At this time, the anti-misinsertion component 3 begins to play an alignment guiding role. The trapezoidal first protrusion 31 on the outer wall of the front end of the second housing 12 first contacts the adapter structure of the external device interface. If the insertion direction is deviated, the trapezoidal structure of the first protrusion 31 will form a limiting block to avoid forced misinsertion. At the same time, the second protrusion 32, which is perpendicular to the outer wall of the first housing 11, guides the first housing 11 and the second housing 12 to be aligned synchronously with the corresponding guide structure of the external device along the insertion direction to ensure the accuracy of the overall insertion direction. When the insertion direction is correct, the insertion block 24 in the connecting frame 23 is gradually inserted into the external device interface. As the insertion depth increases, the abutment plate 34 in the mounting groove 33 symmetrically opened on both sides of the first housing 11 is subjected to the squeezing force of the inner wall of the external device interface and rotates along the rotation axis into the mounting groove 33 until it is completely attached to the bottom wall of the mounting groove 33 and is in a retracted state, which will not hinder the continuous insertion process. When the insertion block 24 is fully inserted into the external device, the connecting frame 23 and the external device interface form a surface contact insertion fit. At this time, the torsion spring 35 in the mounting hole of the abutment plate 34 releases the elastic force, and one end of it drives the abutment plate 34 to reset, so that the abutment plate 34 is tightly pressed against the inner wall of the external device. The continuous elastic force of the torsion spring 35 realizes the stable connection between the abutment plate 34 and the external device, and avoids loosening after insertion. At this time, the first protrusion 31, the second protrusion 32, and the abutment plate 34 are evenly distributed around the first housing 11, and the triple anti-misinsertion limiting structure is fully effective. The optical module body 21 realizes signal transmission with external devices through the external port 22 on the first housing 11. When the optical module needs to be pulled out, the operator holds the handle 13 and applies a pulling force outward. The clamping force of the inner wall of the external device on the abutment plate 34 gradually disappears. Under the elastic action of the torsion spring 35, the abutment plate 34 is further reset and disengaged from the abutment state with the inner wall of the external device. The first protrusion 31 and the second protrusion 32 assist the optical module to be pulled out smoothly along the guide direction. The entire insertion and removal process is achieved through the structural cooperation of the anti-misinsertion component 3, realizing the dual effect of correct insertion guidance and misinsertion protection.
