Technical Field

[0001] This application relates to the field of optical fiber connectivity, and in particular to a multi-core fusion splicing module box. Background Technology

[0002] With the accelerated advancement of global digitalization, the rapid deployment of communication networks, and the expansion of fiber optic network scale, the demand for fusion splice boxes has also increased dramatically. Existing fusion splice boxes are large in size and can only accommodate a small number of fiber cores, making it difficult to meet the high-density cabling requirements of modern communication networks. Furthermore, the connection between the fusion splice tray and the box is usually fixed or bolted, which does not meet the requirements for rapid installation and deployment, resulting in low efficiency in fiber optic splicing and hindering the network deployment needs for accelerated deployment.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples.

[0044] The fusion splice box is mainly used to coil excess fiber cores during optical cable splicing, then encapsulates them inside, and finally installs them in the optical cable distribution box. For ease of description, the embodiments of this application use... Figure 1 and Figure 2 The directions shown are front-back, left-right, up-down, and down-up directions, where the front-back direction corresponds to the width direction of the base plate 11, the left-right direction corresponds to the length direction of the base plate 11, and the up-down direction corresponds to the thickness direction of the base plate 11.

[0045] Example 1: Please refer to Figure 1and Figure 2 This application discloses a multi-core fiber optic module box according to Embodiment 1, comprising a box body 1, a box cover 3, and at least one fiber optic tray 2. The fiber optic tray 2 is located inside the box body 1 and is detachably connected to the box body 1. The box cover 3 is detachably connected to the box body 1. The box body 1 includes a base plate 11, a second side plate 121, a third side plate 122, and a fourth side plate 123. The third side plate 122 and the fourth side plate 123 are disposed opposite each other at both ends of the base plate 11 along its length and are perpendicular to the base plate 11. The first side of the box body 1 is provided with a plurality of pigtail interfaces 131, which are used for... For connecting pigtails, the housing 1 includes at least one optical cable inlet 14, which serves as a channel for external optical cables to enter the housing 1. The second side plate 121 has multiple communication interfaces for installing communication connectors 102. The pigtail interface 131 is opposite to the optical cable inlet 14. The external optical cable has multiple optical fibers, each of which is fused to a pigtail. At least one fusion splice tray 2 is located between the pigtail interface 131 and the optical cable inlet 14 for installing a heat fusion sleeve for splicing pigtails and optical fibers, in order to position the fused pigtails and optical fibers.

[0046] like Figure 3 and Figure 4 As shown, the base plate 11 is provided with at least one card interface. The fusion splice tray 2 includes at least one card connector. The card connector is adapted to engage with the card interface. The card interface is provided with a limiting part 1123. When the card connector is connected to the card interface, the limiting part 1123 can avoid the card connector to allow it to smoothly enter the card interface. After the card connector engages with the corresponding card interface, the limiting part 1123 resets to restrict the movement of the card connector and prevent it from exiting the card interface, thereby achieving a stable connection between the fusion splice tray 2 and the base plate 11 and preventing the fusion splice tray 2 from detaching from the housing 1. The engagement connection between the fusion splice tray 2 and the base plate 11 enables quick assembly and disassembly, improving installation efficiency. The limiting part 1123 limits the card connector to prevent loosening and ensures connection stability. Different numbers of fusion splice trays 2 can be installed in the housing 1. The number of card interfaces is adjusted according to the number of fusion splice trays 2 to suit splicing operations with different numbers of fiber cores.

[0047] like Figure 3As shown, the card interface includes a first card interface 111 and a second card interface 112, and the card connector includes a first card connector 211 and a second card connector 212. The first card connector 211 is correspondingly engaged with the first card interface 111, and the second card connector 212 is correspondingly engaged with the second card interface 112. The first card interface 111 is in a "convex" shape on the inner surface of the bottom plate 11 and penetrates through the bottom plate 11. It includes a first section 1111 and a second section 1112. The length and width dimensions of the first section 1111 are larger than those of the second section 1112, and the opening dimension of the first section 1111 is larger than the dimension of the first card connector 211, enabling the first card connector 211 to be smoothly inserted into the first section 1111. The dimension of the second section 1112 is adapted to the first card connector 211, enabling the first card connector 211 to be engaged and connected with the second section 1112. Specifically, the second section 1112 includes a first bayonet 1113 on the inner surface of the bottom plate 11 and a second bayonet 1114 on the outer surface of the bottom plate 11. The second bayonet 1114 is larger than the first bayonet 1113. There are two opposite engaging surfaces 1115 between the first bayonet 1113 and the first bayonet 1113, and the two engaging surfaces 1115 are inclined with respect to the bottom plate 11. As Figure 6 and Figure 7 shown, the first card connector 211 includes a trapezoidal portion with a narrow upper part and a wide lower part. The top surface of the trapezoidal portion is connected to the bottom of the fiber optic splice tray 2, and the bottom surface is away from the bottom of the fiber optic splice tray 2. The first card connector 211 has two opposite inclined sides 2111, and the two inclined sides 2111 are inclined with respect to the bottom surface of the trapezoidal portion. When the first card connector 211 is engaged with the first card interface 111, it first enters the interface of the first section 1111 from above the bottom plate 11, and then moves in the direction of the second section 1112 until it abuts against the second section 1112. At this time, the two inclined sides 2111 and the two engaging surfaces 1115 also come into contact, realizing the engagement of the first card connector 211 with the first card interface 111. The two engaging surfaces 1115 restrict the first card connector 211 from moving forward, backward, and upward. The bottom of the fiber optic splice tray 2 contacts the inner surface of the bottom plate 11, restricting the first card connector 211 from moving downward. The end of the first card connector 211 abuts against the second section 1112 and cannot move to the left, achieving rapid engagement.

[0048] Please continue to refer to Figure 3The second card interface 112 includes a third segment 1121 and a fourth segment 1122. The length and width of the third segment 1121 are greater than the length and width of the fourth segment 1122, and the opening size of the third segment 1121 is greater than the size of the second card connector 212, so that the second card connector 212 can be inserted into the third segment 1121. The size of the fourth segment 1122 is adapted to the second card connector 212, so that the second card connector 212 can be engaged and connected with the fourth segment 1122. The structural dimensions of the fourth segment 1122 are the same as those of the second segment 1112. The structural dimensions of the second card connector 212 are the same as those of the first card connector 211. The positional order of the first segment 1111 and the second segment 1112 is the same as that of the third segment 1121 and the fourth segment 1122. The first card connector 211 and the second card connector 212 move simultaneously in the same direction. The third segment 1121 is provided with a limiting part 1123, which is in the shape of a long strip plate. Its first end is connected to the bottom plate 11, and its second end extends toward the fourth segment 1122 until it is located at the junction of the third segment 1121 and the fourth segment 1122. The second end is freely set and is not connected to any part. Its two sides are also freely set. Therefore, the second end of the limiting part 1123 can move up and down elastically within the third segment 1121 under the interference of external force. When the second card connector 212 connects to the second card interface 112, the second end of the limiting part 1123 is first pressed down to move it downward, creating space for the second card connector 212 to enter the third segment 1121. Then, the second card connector 212 moves towards the fourth segment 1122 and enters the fourth segment 1122 until it is abutted and can no longer move. At this point, its two oblique sides 2111 contact the two card-connecting surfaces 1115 of the fourth segment 1122 to achieve engagement. The two card-connecting surfaces 1115 restrict the second card connector 212 from moving forward. The fiber fusion tray 2 moves backward and upward, and its bottom contacts the inner surface of the base plate 11, restricting the second locking member 212 from moving downward. The end of the second locking member 212 abuts against the fourth segment 1122 and cannot move to the left. The second end of the limiting part 1123 resets to limit the second locking member 212, preventing it from moving to the right and avoiding it from exiting the fourth segment 1122. Thus, the second locking member 212 is restricted from moving in any direction, and consequently, the first locking member 211 is also restricted from moving in any direction, achieving a stable connection between the fiber fusion tray 2 and the base plate 11. Figure 2 As shown, after the fiber fusion tray 2 is snapped into the base plate 11, the limiting part 1123 is partially exposed outside the fiber fusion tray 2. When it is necessary to disassemble the fiber fusion tray 2, press down on the exposed part of the limiting part 1123 to make its second end move downward to allow the second snap-fit ​​part 212 to exit the fourth section 1122.

[0049] Please refer to Figure 8This is a schematic diagram showing the first card connector 211 and the first card interface 111 after they are engaged and connected. The oblique side 2111 of the first card connector 211 and the card interface 1115 are in line contact, which reduces friction during the engagement process and provides smooth engagement.

[0050] In this embodiment, the center lines of the first card interface 111 and the second card interface 112 are located on the same straight line. In other embodiments, the first card interface 111 and the second card interface 112 may also be staggered and located on different straight lines. The first card connector 211 and the second card connector 212 are similarly arranged accordingly.

[0051] In this embodiment, 24 pigtail interfaces 131 are provided, forming a 24-core fusion splice module box. The 24 pigtail interfaces 131 are arranged one by one along the length of the base plate 11. Two optical cable inlets 14 are provided, located at both ends of the base plate 11 along its length. There are two fusion splice trays 2, arranged along the width of the base plate 11. Correspondingly, there are two sets of card interfaces and connectors. The two sets of card interfaces and connectors can be oriented in opposite directions. Each fusion splice tray 2 can accommodate 12 optical fibers. In other embodiments, three sets of card interfaces and connectors can be provided to install three fusion splice trays 2, forming a 36-core fusion splice module box. In other embodiments, the number of card interfaces and connectors can be fixed at four sets, and the number of fusion splice trays 2 installed can be selected according to actual communication requirements, allowing for arbitrary adaptation between 12-core and 48-core fusion splice modules.

[0052] The multi-core fusion splicing module box provided in this application embodiment has a modular design that enables factory prefabrication and rapid on-site assembly, significantly shortening the construction cycle.

[0053] Please continue to refer to this. Figure 3 and Figure 4Two sets of fiber winding structures 15 are provided on the base plate 11. The two sets of fiber winding structures 15 are symmetrically arranged at the left and right ends of the fiber splicing tray 2, and correspond to the positions of the two optical cable inlets 14 respectively. The fiber winding structure 15 includes a first fiber winding element 151, a second fiber winding element 152, a third fiber winding element 153, and a fourth fiber winding element 154. The first fiber winding element 151, the second fiber winding element 152, the third fiber winding element 153, and the fourth fiber winding element 154 protrude from the base plate 11. The first fiber winding element 151 includes a vertical plate 1511 perpendicular to the base plate 11 and a first top plate 1512 parallel to the base plate 11. The space between the first top plate 1512 and the base plate 11 forms the optical fiber receiving area of ​​the first fiber winding element 151. The second fiber winding element 152 includes an arc-shaped plate 1521 perpendicular to the base plate 11 and two second top plates parallel to the base plate 11. Plate 1522, two second top plates 1522 are connected to both ends of the arc-shaped plate 1521. The third fiber winding component 153 is the same as the first fiber winding component 151 and is symmetrically arranged with respect to the center line of the arc-shaped plate 1521. The first top plate 1512 and the two second top plates 1522 extend towards the outside of the box 1, forming an outward-facing receiving area. The second fiber winding component 152 also includes a third top plate 1523 parallel to the bottom plate 11. The third top plate 1523 is connected to the middle position of the arc-shaped plate 1521 and extends towards the fusion splice tray 2, forming an inward-facing receiving area. The position of the third top plate 1523 is opposite to the position of the fourth fiber winding component 154. After the optical fiber and pigtail are fused and located in the fusion splice tray 2, a certain length of optical fiber will remain in the box 1. This part of the optical fiber is coiled and stored along the receiving areas of the two sets of fiber winding structures 15 to avoid the wires inside the box being messy and to protect the optical fiber from being placed randomly and coming into contact with other components inside the box 1 and being damaged. The radius of the curved plate 1521 is greater than or equal to 30mm to avoid excessive bending that could damage the optical fiber.

[0054] Each fiber winding assembly contains multiple fiber splitting components within its accommodating area. These components have open fiber slots 1551. Each optical fiber or pigtail, upon entering the accommodating area, can be placed within a different fiber slot 1551 for positioning. This maintains the stability of the optical fiber within the accommodating area, preventing it from detaching and becoming disorganized, or from colliding with other sharp parts of the housing 1 and causing damage. Furthermore, the layered placement allows for the orderly differentiation of fiber cores with different markings. For example... Figure 5 As shown, the second fiber winding member 152 has an inwardly facing receiving area, which is provided with three fiber splitting members, which are spaced apart along the height direction of the arc plate 1521.

[0055] like Figure 3 As shown, a cable tray 141 is provided at the optical cable inlet 14. The cable tray 141 is connected to the base plate 11 and communicates with the inside of the housing 1. The cable tray 141 is U-shaped with the opening facing upwards. One side of the cable tray 141 is connected to the third side plate 122 of the housing 1. The cable tray 141 includes at least one cable tie hole 142, such as... Figure 3As shown, the bottom and side of the cable tray 141 have two through-holes 142. The cable tray 141 has openings at both ends, with the first end facing the outside of the housing 1 and the second end facing the inside of the housing 1. The optical cable enters the cable tray 141 from the first end and enters the housing 1 through the second end. Cable ties can pass through the through-holes 142 on the side of the cable tray 141 and extend from the through-holes 142 at the bottom, thus fixing the optical cable inside the cable tray 141 to prevent shaking and affecting the subsequent fiber splicing coil 2. A fifth side plate 124 connects the second end of the cable tray 141 to the second side plate 121. The fifth side plate 124 is inclined relative to the second side plate 121, forming a first operating area for the cable ties between the cable tray 141 and the fifth side plate 124, facilitating technicians to bind the cable ties and place the cable tie heads in this first operating area for storage.

[0056] like Figure 4 As shown, the first side of the box body 1 is provided with an upper plate 132 and a lower plate 133. The upper plate 132 and the lower plate 133 are parallel to the bottom plate 11. The lower plate 133 is connected to the bottom plate 11. The upper plate 132 is connected to the top of the fourth side plate 123 and the third side plate 122. The two ends of the two plates in the length direction are respectively connected to the fourth side plate 123 and the third side plate 122. Multiple partitions 134 are provided between the two plates. The multiple partitions 134 are perpendicularly connected to the upper plate 132 and the lower plate 133. The space between two adjacent partitions 134 forms a pigtail interface 131. Multiple fastening holes 135 are provided on the upper plate 132 and the lower plate 133 for fastening with the pigtail connector 101. Each partition 134 is provided with a positioning step 1341. The positioning step 1341 faces the inside of the box body 1 and protrudes from the upper plate 132 and the lower plate 133 for supporting and positioning the box cover 3. Multiple pigtail interfaces 131 are constructed using two flat plates and multiple partitions 134, which is simple in structure and easy to process.

[0057] like Figure 4As shown, the second side plate 121 of the box body 1 has a boss 1211 protruding towards the inside of the box body 1. A notch 1212 is provided at the position where the boss 1211 connects with the second side plate 121. The notch 1212 faces outward of the box body 1. A notch 1213 corresponding to the notch 1212 is provided on the second side plate 121. The notch 1212 is used to fasten with the box lid 3. A pressing member 16 is provided on the bottom plate 11. The pressing member 16 includes a vertical section 161, a curvature section 162, an inclined section 163, and a positioning section 164. The vertical section 161 is vertically connected to the bottom plate 11. The curvature section 162 is connected to the vertical section 161. The inclined section 163 is inclined upward relative to the bottom plate 11 and is connected to the end of the curvature section 162 away from the vertical section 161. The positioning section 164 is connected to the end of the inclined section 163 away from the curvature section 162 and protrudes upward. The curvature section 162 is used to realize the elastic deformation of the pressing member 16, and the tilting section 163 is used to move the positioning section 164 away from the base plate 11. The space between the pressing member 16 and the base plate 11 forms a receiving area for accommodating optical fibers, so that the optical fibers are also correspondingly limited in the direction close to the second side plate 121 when they are coiled, and the two fiber winding structures 15 make the optical fibers more stable.

[0058] like Figure 3 and Figure 4 As shown, the inner sides of the fourth side plate 123 and the third side plate 122 of the box body 1 are each provided with two third snap-fit ​​pieces 1221. The two third snap-fit ​​pieces 1221 are spaced apart along the length direction of the corresponding side plate and are used to snap-fit ​​with the box cover 3.

[0059] like Figure 4As shown, the box body 1 is also provided with two elastic mounting members 17 for connection to the wiring box. The two elastic mounting members 17 are respectively connected to the third side plate 122 and the fourth side plate 123. The elastic mounting member 17 connected to the fourth side plate 123 includes a guide rail 171 and an elastic piece 172. The guide rail 171 is connected to the outer surface of the fourth side plate 123, and its length direction is the same as the length direction of the fourth side plate 123, extending from the middle of the fourth side plate 123 to a position near the first side. The first end of the elastic piece 172 is connected to the guide rail 171, and the second end extends towards the first side and protrudes from the first side. The elastic piece 172 does not contact the fourth side plate 123 and can move elastically in a direction close to or away from the fourth side plate 123. A fourth snap-fit ​​member 173 is provided on the outer side of the elastic piece 172, which is used for snap-fit ​​connection with the wiring box, making the box body 1 stably connected to the wiring box. The second end of the elastic sheet 172 is provided with a first anti-slip part 174 to prevent the technician's hand from slipping when pressing the elastic sheet 172, thus affecting installation efficiency. The wiring box is provided with a mounting slot and a locking slot. The mounting slot is adapted to the guide rail 171 for insertion, and the locking slot is adapted to the fourth locking member 173. When connecting the module box to the wiring box, it is first inserted into the mounting slot via the guide rail 171 and slides along the mounting slot into the wiring box until the fourth locking member 173 engages with the locking slot. At this time, the first anti-slip part 174 is located outside the mounting slot. When the module box needs to be disassembled, the technician presses the two elastic mounting members 17, causing the fourth locking member 173 to disengage from the locking slot, and then pulls the module box out of the mounting slot. The two elastic mounting members 17 are symmetrically arranged.

[0060] Please refer to Figure 6 and Figure 7 This is a schematic diagram of the fiber fusion splice tray 2 provided in the embodiments of this application. The fiber fusion splice tray 2 includes a base 21 and a plurality of fiber fusion grooves 22. The plurality of fiber fusion grooves 22 are arranged in an array. The inlets of the plurality of fiber fusion grooves 22 face the fiber winding structure 15 on the same side. The plurality of fiber fusion grooves 22 are snapped into heat shrink tubes for splicing optical fibers and pigtails one by one. The bottom of the base 21 is provided with a first snap-fit ​​member 211 and a second snap-fit ​​member 212.

[0061] Please refer to Figure 9 and Figure 10This is a schematic diagram of the box cover 3 provided in an embodiment of this application. The box cover 3 includes a first side 311, a second side 312, a third side 313, and a fourth side 314. The first side 311 and the second side 312 are opposite to each other, and the third side 313 and the fourth side 314 are opposite to each other. The first side 311 of the box cover 3 is provided with a plurality of insertion interfaces 321. The number of insertion interfaces 321 is the same as the number of partitions 134, and their positions correspond one-to-one. The insertion interfaces 321 are adapted to be inserted into the partitions 134, and are supported and positioned by the positioning steps 1341 of the partitions 134. The fourth side 314 and the third side 313 of the lid 3 are each provided with two sliding grooves 331 and two positioning grooves 332. The opening of the sliding groove 331 is located at the bottom of the lid 3, and the opening of the positioning groove 332 is located at the top of the lid 3. The sliding groove 331 and the positioning groove 332 are connected through the groove wall. The size of the sliding groove 331 and the positioning groove 332 are adapted to the third snap-fit ​​component 1221 and their positions correspond. When the lid 3 is connected to the box body 1, the sliding groove 331 is first covered on the corresponding third snap-fit ​​component 1221, and then the lid 3 is pushed towards the first side 311 so that the third snap-fit ​​component 1221 enters the positioning groove 332 to realize the snap-fit ​​connection between the lid 3 and the box body 1. The multiple insertion interfaces 321 are also correspondingly inserted into the multiple partitions 134 one by one. The second side 312 of the lid 3 has grooved covers at both ends that fit the groove 141. A second operating area is provided between the grooved covers and the second side 312. The second operating area has the same shape and size as the first operating area and is positioned accordingly. A protruding edge 341 extends downward from the second side 312. The protruding edge 341 protrudes towards the center of the lid 3. The size of the protruding edge 341 matches the size of the recess 1212. It can be inserted into the recess 1212 through the notch 1213 to achieve a snap-fit ​​connection between the lid 3 and the box body 1. A pressing plate 342 is also provided on the lid 3. The pressing plate 342 is close to the second side 312. The position of the pressing plate 342 corresponds to the position of the pressing member 16. The first end of the pressing plate 342 is connected to the lid 3, and the rest of the position is free, so that it can move elastically in the vertical direction of the lid 3. A baffle 344 extends downward from the bottom of the second end of the pressing plate 342. The first and second ends of the pressing plate 342 are opposite each other. A stop block 343 extends downward from the bottom of the lid 3. The stop block 343 and the baffle 344 are opposite each other, and the space between them forms a limiting groove that fits into the positioning section 164. Thus, the stop block 343 and the baffle 344 are restricted by the positioning section 164 and cannot move in the back and forth direction, preventing the protruding edge 341 from exiting the recess 1212 and avoiding unstable connection between the lid 3 and the box body 1. The top surface of the pressing plate 342 is provided with a striped second anti-slip part 3421, which increases the friction between the pressing plate 342 and the technician's fingers, facilitating downward pressing and outward dragging of the lid 3.

[0062] In this embodiment, the four sides of the lid 3 are stably connected to the four sides of the box body 1 through the positioning of the insertion interface 321 and the positioning step 1341, the engagement of the positioning groove 332 and the third snap-fit ​​member 1221, and the fastening connection of the protruding edge 341 and the recess 1212. When it is necessary to open the lid 3, first apply downward pressure to the pressing plate 342, so that the baffle 344 presses the inclined section 163 of the pressing member 16, causing the positioning section 164 to move downward and disengage from the limiting groove. Then, the lid 3 is dragged towards the second side 312, so that the protruding edge 341 disengages from the recess 1212, the third snap-fit ​​member 1221 disengages from the positioning groove 332, and the insertion interface 321 separates from the partition 134, thereby separating the lid 3 from the box body 1.

[0063] In this embodiment, the box body 1 is integrally injection molded from plastic material. After the fiber winding parts and pressing parts 16 are formed, through process holes are formed on the bottom plate 11. This application can also use these process holes as heat dissipation holes to dissipate heat and cool down the box body 1.

[0064] Example 2: Please refer to Figure 11 This is a schematic diagram of the multi-core fusion splice module box provided in Embodiment 2 of this application. The difference between Embodiment 2 and Embodiment 1 is that a semiconductor heat sink 41 is installed on the bottom plate 11 of the box body 1. The cold end of the semiconductor heat sink 41 is connected to the interior of the box body 1, while the hot end of the semiconductor heat sink 41 is located outside the box body 1 and connected to a miniature exhaust fan (not shown in the figure). Natural heat dissipation through the heat dissipation holes of the fusion splice module box is relatively slow and easily leads to heat accumulation. This application uses the semiconductor heat sink 41 to accelerate the absorption and dissipation of heat inside the box body 1 to the wiring box, and then quickly dissipates it through the wiring box's heat dissipation system, improving the overall heat dissipation efficiency of the fusion splice module box and the wiring box.

[0065] Example 3: Please refer to Figure 12This is a schematic diagram of the optical cable inlet 14 provided in Embodiment 3 of this application. The difference between Embodiment 3 and Embodiment 1 lies in the structure of the optical cable inlet 14. In Embodiment 3, the optical cable inlet 14 includes an optical cable groove 143 and a flip cover 144. The first side of the flip cover 144 is hinged to the first groove wall of the optical cable groove 143, and the second side is detachably connected to the second groove wall 1432 of the optical cable groove 143. The first groove wall and the second groove wall 1432 are opposite to each other. The flip cover 144 is in the shape of an arc-shaped thin plate, and a first retaining strip 145 is provided on its second side. The first retaining strip 145 extends along the length direction of the flip cover 144. The second groove wall 143 of the optical cable groove 144... 32 is provided with a second locking strip 146, which extends along the length of the optical cable groove 143. The first locking strip 145 is provided with a first protrusion 1451 facing upward, and a first recess is provided between the first protrusion 1451 and the second side of the flip cover 144. The second locking strip 146 is provided with a second protrusion 1461 facing downward, and a second recess is provided between the second protrusion 1461 and the second groove wall 1432. The first protrusion 1451 and the second recess are adapted to be engaged, and the second protrusion 1461 and the first recess are adapted to be inserted. When the optical cable is laid from the optical cable tray 143 into the housing 1, the flip cover 144 is first flipped so that its second side is away from the optical cable tray 143 to facilitate the entry of the optical cable. Then, the first locking strip 145 and the second locking strip 146 are fastened together, so that the flip cover 144 tightly presses and fixes the cable. Multiple second locking strips 146 can be provided to adjust the degree of tightness of the cable and to tighten and fix optical cables of different diameters, such as... Figure 12 As shown, this embodiment is provided with three second locking strips 146, which are spaced apart along the height of the groove wall. The flip cover 144 can select different positions of the second locking strips 146 for fastening connection according to the size of the optical cable diameter, so as to accommodate optical cables with different fiber cores. The optical cable can be quickly fixed by fastening the flip cover 144 to the optical cable groove 143. By setting multiple second locking strips 146 at different positions, the tightness of the flip cover 144 on the optical cable can be adjusted and it can accommodate optical cables with different fiber cores. The flip cover 144 is set in the shape of an arc-shaped thin plate, and its curvature can be deformed to form a telescopic flip cover 144, so as to be able to be fastened with the second locking strips 146 at different positions.

[0066] Please refer to Figure 13This document provides a schematic diagram of the fiber coiling inside the 24-core fiber fusion splicing module box provided in the above embodiments of this application. After entering the box, the optical cable 103 is coiled through the outward-facing receiving area of ​​the second fiber winding member 152 on the same side to the entrance on the same side of the fiber fusion splicing tray 2 and enters the fiber fusion groove. The pigtail passes through the receiving areas of the third fiber winding member 153, the inward-facing receiving area of ​​the second fiber winding member 152 on the same side, and the receiving area of ​​the first fiber winding member 151 on the same side, then to the receiving areas of the first fiber winding member 151 and the outward-facing receiving areas of the second fiber winding member 152 on the other side, extending into the fiber fusion splicing tray 2. The fibers are coiled in layers, arranged in a staggered manner.

[0067] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
