[0057] The multi-core fusion fiber module box provided by the embodiment of the present application can realize factory prefabrication and on-site rapid assembly, and greatly shorten the construction period.

[0058] Please continue to refer to 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.

[0059] 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.

[0060] 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 wire slot 141 are provided with two through cable tie holes 142, and the two ends of the wire slot 141 are provided with holes, wherein the first end is towards the outside of the box body 1, and the second end is towards the inside of the box body 1, and the optical cable enters the wire slot 141 from the first end and enters the box body 1 through the second end. The cable tie can be inserted from the cable tie hole 142 on the side of the wire slot 141 and extended from the cable tie hole 142 on the bottom, so as to fix the optical cable in the wire slot 141 and avoid shaking and affecting the subsequent fiber fusion disc 2. The second end of the wire slot 141 is connected with the fifth side plate 124 between the second side plate 121, the fifth side plate 124 is inclined relative to the second side plate 121, and the wire slot 141 and the fifth side plate 124 form a first operation area of the cable tie, which is convenient for technicians to bundle the cable tie and place the cable tie head in the first operation area for storage.
