Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical fiber communication technology, and in particular to an optical fiber coupler packaging component. Background Technology
[0002] Fiber optic couplers are components used to split / combine optical signals or extend fiber optic links. They belong to the field of passive optical components and are used in telecommunications networks, cable television networks, user loop systems, and local area networks. Fiber optic couplers typically rely on sealant to improve their sealing performance. However, the sealant deteriorates after a period of use, reducing the sealing effect. Therefore, patent publication number CN214895897U proposes "a fiber optic coupler packaging device" that uses two detachable packaging sections and a sealing strip to replace the traditional glue sealing method. This improves the sealing effect, maintains it for a longer time, and maximizes the prevention of air from entering the device through the connection between the lower and upper packaging sections.
[0003] However, this solution uses the combination of a sealing cap and a mounting plate to splice and fix the two encapsulation parts. During disassembly and assembly, the sealing cap needs to be rotated frequently, which not only reduces the efficiency of disassembly and assembly, but also makes disassembly difficult because the threaded connection may rust, seize, or stick due to long-term use. In view of the above reasons, this application proposes a fiber optic coupler encapsulation assembly. Utility Model Content

[0036] Example
[0037] like Figure 1-4 As shown, the present invention proposes an optical fiber coupler packaging assembly, including a metal cylinder 1, a metal optical fiber 3 inside the metal cylinder 1, and a sealing part 4 and a sealing part 5 on the outside of the metal cylinder 1. Both ends of the sealing part 4 and the sealing part 5 are provided with two semi-circular holes, and the inner diameter of the semi-circular holes is the same. A semi-circular sealing ring 6 is provided in each of the semi-circular holes, and the semi-circular sealing ring 6 is attached to the metal optical fiber 3. The semi-circular holes on one side of the sealing part 4 and the sealing part 5 can be spliced to form a circular hole for the metal optical fiber 3 to extend out. The side of the sealing part 4 near the sealing part 5 is provided with two slots 7 for limiting, and the top inner wall of the two slots 7 is provided with positioning grooves 8 for positioning. The side of the sealing part 5 near the sealing part 4 is provided with two positioning structures 9 for assembling the sealing part 4 and the sealing part 5.
[0038] The positioning structure 9 includes an insert plate 901 for installation. The top of the insert plate 901 is provided with a storage groove 902. A positioning post 906 for positioning is movably disposed in the storage groove 902. A guide plate 904 is fixedly disposed on the top of the spring 903. The top of the guide plate 904 is fixedly connected to the bottom of the positioning post 906. The guide plate 904 and the storage groove 902 are movably connected. Limiting grooves are provided on both inner walls of the storage groove 902. Limiting blocks 905 are fixedly disposed on both sides of the guide plate 904. The limiting blocks 905 are movably connected to the limiting grooves. A spring 903 for applying thrust is provided below the positioning post 906. The positioning structure 9 can improve the efficiency of disassembly and assembly of the encapsulation part.
[0039] Two heat-conducting plates 2 are fixedly installed on the outside of the metal cylinder 1. Both the first encapsulation part 4 and the second encapsulation part 5 are provided with heat dissipation structures 10. The heat dissipation structure 10 includes a heat dissipation plate 101 for improving heat dissipation efficiency. The arrangement of the heat-conducting plates 2 and the heat dissipation plate 101 can achieve heat dissipation of the equipment. Both ends of the heat dissipation plate 101 are provided with mounting grooves 102. Both mounting grooves 102 are movably provided with telescopic plates 103. The adjustable telescopic plates 103 can change the area of the heat dissipation surface of the equipment and optimize the heat dissipation performance of the equipment. The top inner wall and the bottom inner wall of the mounting groove 102 are provided with sliding grooves. The top and bottom of the telescopic plate 103 are fixedly provided with sliders 104. The sliders 104 and the sliding grooves are movably connected. The second spring 105 is fixedly installed in the mounting groove 102. The other end of the second spring 105 is fixedly connected to the telescopic plate 103. Two positioning bolts 106 are movably provided on the front of the heat dissipation plate 101. The front of the telescopic plate 103 is provided with insertion holes.
[0040] In this embodiment, when assembling the first packaging part 4 and the second packaging part 5, the multiple positioning posts 906 are first pressed downwards. The positioning posts 906 press against the guide plate 904, and the guide plate 904 presses against the bottom spring 903. After the positioning posts 906 are completely submerged in the receiving groove 902, the insert plate 901 is inserted into the slot 7. When the positioning posts 906 move to the position of the positioning groove 8, the spring 903 pushes the guide plate 904 upwards. The guide plate 904 then drives the positioning posts 906 and causes them to pop out of the positioning groove 8, thus assembling the first packaging part 4 and the second packaging part 5. At this time, the heat sink 101 and the heat conduction sheet 2 are in contact. At this time, the semi-circular sealing ring 6 on one side of the first packaging part 4 and the semi-circular sealing ring 6 on one side of the second packaging part 5 are in contact. The circular sealing ring 6 is circular, and its inner wall is attached to the metal optical fiber 3 to seal the outlet. When it is necessary to separate the first encapsulation part 4 and the second encapsulation part 5, multiple positioning posts 906 are pressed down at the same time. After the positioning posts 906 are completely retracted into the receiving groove 902, the first encapsulation part 4 and the second encapsulation part 5 are pulled in opposite directions to separate the two encapsulation parts. The heat dissipation of the equipment can be achieved by setting the heat conduction plate 2 and the heat dissipation plate 101. If the heat dissipation requirement is large, the positioning bolt 106 can be rotated counterclockwise to make one end of it come out of the insertion hole on the front of the telescopic plate 103. The second spring 105 pushes the telescopic plate 103 out, which can expand the heat dissipation area of the equipment and improve the heat dissipation efficiency of the equipment.
[0041] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
