DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with embodiments.

[0022] See also Figure 1-4 The utility model provides a pluggable optical module with good stability, including an optical module body 1 and a switch cage slot 2, an electrical port 3 is arranged at the rear end of the optical module body 1, an optical port 4 is arranged at the front end of the optical module body 1, clamping holes 5 are opened on both sides of the optical module body 1, and clamping mechanisms 6 corresponding to the clamping holes 5 are arranged on both sides of the switch cage slot 2. A plurality of evenly distributed elastic sheets 7 are fixedly connected to the top and bottom of the optical module body 1, and two dust plugs 8 are detachably connected to the front end of the optical module body 1, and a mounting plate 9 is fixedly connected to the front end of the two dust plugs 8, and a pull handle 10 is fixedly connected to the front end of the mounting plate 9.

[0023] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the outer wall of the optical module body 1 is coated with a silicon carbide ceramic coating. The surface area of ​​the ceramic material has about 20% more pores than the metal heat sink, and has a larger contact area with the convection medium air, which can take away more heat in the same unit time and avoid long-term high-temperature operation of the optical module body 1.

[0024] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth explaining in detail that the outer wall of the optical module body 1 fits tightly with the inner surface of the switch cage slot 2, ensuring that the optical module body 1 can smoothly enter the inner surface of the switch cage slot 2 and smoothly realize the plugging and unplugging work, thereby achieving high-speed, long-distance and stable data transmission.

[0025] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the outer walls of the two dust plugs 8 are both sleeved with anti-slip sleeves, which increase the friction between the outer walls of the dust plugs 8 and the inner walls of the optical port 4, so that the outer walls of the dust plugs 8 fit tightly with the inner walls of the optical port 4, preventing dust from entering the interior of the optical module body 1 from the optical port 4 and causing damage to its internal electronic components.

[0026] According to the above working process, it can be known that by setting the dust plug 8, the optical module body 1 can be protected from dust, and dust can be prevented from entering the optical module body 1 from the optical port 4 to damage its internal electronic components. At the same time, a heat dissipation layer made of silicon carbide ceramic material is set, which can quickly take away the heat generated by the operation of the optical module body 1, avoid the optical module body 1 from running at high temperature for a long time, and effectively extend its service life.

[0027] Further as Figure 4 As shown, it is worth specifically explaining that the clamping mechanism 6 includes a through slot 601 opened inside the switch cage slot 2, the inner wall of the through slot 601 is rotatably connected with a rotating shaft 602, the outer wall of the rotating shaft 602 is fixedly connected with a lock 603, the outer side of the lock 603 is fixedly connected with a slide plate 604, and the inner side of the lock 603 is fixedly connected with a spring 605. By setting the clamping mechanism 6, the lock 603 is engaged and locked with the clamping hole 5, completing the detachable connection between the optical module body 1 and the switch cage slot 2, greatly increasing the plug-in stability of the optical module body 1, and preventing the optical module body 1 from being loosened by external force and causing abnormal signal transmission.

[0028] Further as Figure 4 As shown, it is worth explaining in detail that a limiting groove corresponding to the slide plate 604 is opened inside the switch cage slot 2, which limits the movement of the slide plate 604 so that it can only move in the horizontal direction, thereby cooperating with the spring 605 to press and reset the lock 603.

[0029] Further as Figure 4 As shown, it is worth explaining in detail that the snap-in hole 5 is tightly engaged with the lock buckle 603. With the cooperation of the snap-in hole 5, the lock buckle 603 locks the inner wall of the snap-in hole 5, completing the detachable connection between the optical module body 1 and the switch cage slot 2, which facilitates the installation and disassembly of the optical module body 1.

[0030] This solution has the following working process: in actual use, the optical module body 1 is aligned with the inner wall of the switch cage slot 2 and inserted. Under the action of the spring 605, the lock buckle 603 is driven to engage and lock with the card hole 5 to complete the detachable connection between the optical module body 1 and the switch cage slot 2, which greatly increases the plug-in stability of the optical module body 1. Then, the handle 10 is pulled out to remove the dust plug 8, and the optical fiber connector is inserted into the optical port 4 to complete the connection and perform data transmission. During use, the heat dissipation layer made of silicon carbide ceramic material promptly takes away the heat generated by the operation of the optical module body 1. When disassembling, only the slide plate 604 needs to be pressed inward to drive the lock buckle 603 to rotate and unlock, and then the optical module body 1 can be pulled out.

[0031] In summary: by setting the dust plug 8, the optical module body 1 can be protected from dust, preventing dust from entering the optical module body 1 from the optical port 4 and causing damage to its internal electronic components. At the same time, a heat dissipation layer made of silicon carbide ceramic material is provided, which can quickly take away the heat generated by the operation of the optical module body 1, avoiding the long-term high-temperature operation of the optical module body 1, and effectively extending its service life; by setting the card connection mechanism 6, the lock buckle 603 is engaged and locked with the card connection hole 5, completing the detachable connection between the optical module body 1 and the switch cage slot 2, greatly increasing the plug-in stability of the optical module body 1, and avoiding the optical module body 1 from being loosened by external force and causing abnormal signal transmission.
