[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1, reference Figure 1 to Figure 5, which is the first embodiment of the utility model, and provides a protective structure. The installation component 100 includes a fusion splice tray 101 and a cover plate 102 rotatably installed on the fusion splice tray 101. The edge of the fusion splice tray 101 is provided with a wiring port 103. When the device is used, the optical fiber and the pigtail separated from the optical cable are first placed in the fusion splice tray 101 through the wiring port 103 in sequence for fixing, and then the cover plate 102 is covered to complete the fixing of the optical fiber. The sealing component 200 includes a wire entry hole 201 arranged on the wiring port 103, and a sealing ring 201 is provided on the wire entry hole 201. 03, and the sealing ring 203 is made of elastic material, and a wire entry hole 201 matching the appearance of the optical fiber is provided at the wiring port 103, which is convenient for sealing the fusion splice tray 101, and the sealing ring 203 provided at the wiring port 103 can fit the outside of the optical fiber, further improving the sealing performance at the wiring port 103, the fixing component 300, including a fixing magnet 301 fixedly mounted on the cover plate 102, wherein the setting of the fixing component 300 is to fix the cover plate 102 on the fusion splice tray 101, so that it will not easily fall off from the fusion splice tray 101 under the action of external force, thereby achieving the effect of protecting the optical fiber.

[0030] Furthermore, the sealing assembly 200 also includes a placement groove 208 arranged on the upper part of the sealing ring 203, a sealing plate 202 corresponding to the wiring port 103 is provided on the side of the cover plate 102 close to the fusion plate 101, an extrusion groove 205 is opened on the wiring port 103 and close to the sealing ring 203, an extrusion arc plate 206 for resisting the sealing ring 203 is provided in the extrusion groove 205, an extrusion inclined plate 207 for resisting the extrusion arc plate 206 is provided on the sealing plate 202, and the contact end of the extrusion inclined plate 207 and the extrusion arc plate 206 is set to a smooth curved surface. After the optical fiber is installed, the cover plate 102 is covered. During this process, the sealing plate 202 set on the cover plate 102 will be inserted into the wiring port 103 to achieve the purpose of closing the wiring port 103, and the extrusion inclined plate 207 set at its lower part will contact the extrusion arc plate 206. Figure 4 As shown, the cross-section of the extrusion ramp 207 is triangular, and the internal dimensions decrease in order from top to bottom. Therefore, when the extrusion ramp 207 moves synchronously with the sealing plate 202 to contact the extrusion arc plate 206, the extrusion arc plate 206 will gradually move inward, so that the sealing ring 203 fits the outside of the optical fiber, thereby reducing the assembly gap between the sealing ring 203 and the optical fiber, thereby preventing external dust from entering the interior of the fiber splicing tray and contaminating the optical fiber. In addition, the setting of the smooth curved surface at the contact end of the extrusion ramp 207 and the extrusion arc plate 206 can reduce the damage to the extrusion ramp 207 when it contacts the extrusion arc plate 206, thereby extending its service life.

[0031] Furthermore, the placement groove 208 has a trapezoidal cross-section, and the internal dimensions decrease in order from top to bottom. Since the optical fiber itself is relatively fragile and easily damaged when subjected to external force, the present embodiment provides a placement groove 208 on the sealing ring 203 to facilitate the optical fiber to be directly placed into the sealing ring 203 from the top, thereby avoiding possible damage to the optical fiber when it is squeezed into the sealing ring 203, thereby improving the protection of the optical fiber.

[0032] When in use, the sealing plate 202 and the sealing ring 203 are arranged to seal the connection port 103, thereby preventing foreign matter from entering the inside of the fusion splice tray 101 from the connection port 103 and contaminating the optical fiber. The sealing ring 203 is further fitted to the optical fiber by squeezing the inclined plate 207 and the arc plate 206, thereby reducing the assembly gap between the sealing ring 203 and the optical fiber, and improving the sealing effect of the sealing assembly 200.

[0033] Example 2, reference Figure 1 to Figure 5 , which is the second embodiment of the utility model, is different from the previous embodiment in that it also includes a closed arc plate 204 on both sides of the sealing plate 202 and the extrusion inclined plate 207, and the inner side of the closed arc plate 204 is in contact with the placement groove 208. The closed arc plate 204 can be arranged to fit the placement groove 208 when the cover plate 102 is closed, thereby preventing impurities from entering the fusion tray 101 from the placement groove 208, and realizing the isolation operation of the inside of the fiber splicing tray.

[0034] Furthermore, a fixing groove 302 for accommodating the fixing magnet 301 is provided on the welding plate 101, and an adsorption magnet that attracts the fixing magnet 301 is provided in the fixing groove 302. The cooperation between the fixing magnet 301 and the adsorption magnet in the fixing groove 302 realizes the fixation of the cover plate 102, and the magnetic fixation method avoids the cumbersome steps of tightening or loosening with tools in the traditional screw fixation method. This design makes installation and maintenance work more convenient and efficient, which is conducive to the promotion of the equipment.

[0035] Furthermore, a plurality of mounting holes 104 are provided at the bottom of the inner cavity of the splicing tray 101, and mounting screws 105 are threadedly installed in the mounting holes 104. The arrangement of the mounting screws 105 and the mounting holes 104 facilitates the staff to install the splicing tray to a suitable position, and the mechanical seal between the mounting holes 104 and the mounting screws 105 can prevent impurities from entering the splicing tray 101 through the mounting holes 104.

[0036] When in use, the closing operation of the placement slot 208 is realized by setting the closed arc plate 204, and the magnetic fixation of the cover plate 102 is realized by the cooperation of the fixed magnet 301 and the adsorption magnet, thereby avoiding the cumbersome steps of tightening or loosening with tools in the traditional screw fixing method, which is conducive to the promotion of the device.

[0037] Example 3, reference Figure 6 and Figure 7 , which is the third embodiment of the utility model, and this embodiment further provides a fiber splicing tray. It includes a ventilation component 400, including a vent hole 401 arranged on the inner wall of the splicing tray 101, and the cross section of the vent hole 401 is S-shaped. During the use of the splicing tray, especially when performing operations such as optical fiber splicing, a certain amount of heat will be generated. The sealing operation of the splicing tray is realized by implementing a sealing component 200. Although this can prevent external impurities and water vapor from entering the interior of the splicing tray, it also isolates the heat dissipation channel of the heat inside the splicing tray, making the heat dissipation efficiency of the splicing tray low, resulting in the possibility that the temperature inside the splicing tray may rise, and high heat will affect the normal use of the optical fiber. In this embodiment, the vent hole 401 is set, so that the heat inside the splicing tray can be discharged through the vent hole 401, and the S-shaped setting is used to increase the difficulty of dust entering the interior of the splicing tray, and reduce the impact of dust on the optical fiber inside the splicing tray. The clamping assembly 500 includes a clamping block 501 arranged in a linear array at the bottom of the splicing tray 101, and a clamping cavity 502 for clamping the optical fiber splice is constructed between the clamping blocks 501, wherein the clamping cavity 502 is provided for installing the optical fiber and the pigtail splice, which can reduce the looseness caused by external force and improve the stability of the optical fiber connection.

[0038] Furthermore, a dust baffle 402 is provided in the air vent 401, and a certain gap is left between the dust baffle 402 and the top and bottom walls of the air vent 401. The heat dissipation airflow in the fiber splicing tray can flow out from the gap between the dust baffle 402 and the air vent 401, and impurities such as dust from the outside will be blocked by the dust baffle 402 when entering the interior of the fiber splicing tray along the air vent 401, and then remain in the air vent 401. When the heat dissipation airflow flows, it will be entrained and carried out of the air vent 401, thereby reducing the amount of dust entering the interior of the fiber splicing tray.

[0039] Furthermore, the clamping block 501 is made of elastic material. The clamping block 501 made of elastic material has a certain flexibility when fixing the optical fiber, which can reduce the damage to the optical fiber during the fixing.

[0040] When in use, the heat inside the splice tray can be discharged from the vent holes 401 through the vent holes 401, and the S-shaped setting increases the difficulty of dust entering the splice tray, reducing the impact of dust on the optical fibers inside the splice tray.

Therefore, the present invention is not limited to a specific embodiment, but extends to various modifications that still fall within the scope of the appended claims.

[0042] Additionally, in order to provide a concise description of example embodiments, all features of an actual embodiment (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention) may not be described.

[0043] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made.
