In particular, when the first mounting assembly 130 includes a limiting plate 131, the limiting plate 131 may be semi-circular, thereby enclosing a semi-closed first mounting location. When the first mounting assembly 130 includes at least two limiting plates 131 disposed in a gap, all of the limiting plates 131 may be surrounded to form a first mounting location.

The shape and size of the first mounting location is adapted to the shape and size of the cable drum 200. For example, if the cable tray 200 includes a cable tray body and the cable tray 200 has a cylindrical structure, the shape of the limiting plate 131 may be circular or arc-shaped, so as to form a cylindrical first installation position, as shown in fig. 7, if the diameter of the first installation position is greater than the outer diameter of the cable tray 200, the cable tray 200 may be placed in the first installation position, so that the outer circumferential wall of the cable tray 200 is clamped with the inner sidewall 131a of the limiting plate 131; if the diameter of the first installation position is smaller than the diameter of the cable drum body, the cable drum body can be sleeved on the periphery of the limiting plate 131, so that the inner wall of the cable drum body is clamped with the outer side wall 131b of the limiting plate 131.

Optionally, the side wall of the limiting plate 131 is provided with a boss 132, the boss 132 is used for fixing the cable drum 200 sleeved on at least one limiting plate 131, and whether the boss 132 is arranged on the inner side wall 131a or the outer side wall 131b of the limiting plate 131 can be determined according to the installation position of the cable drum 200 on the limiting plate 131, so that the cable drum 200 is fixed on the limiting plate 131, and the cable drum 200 is prevented from rotating relative to the limiting plate 131. For example, when the cable drum body 213 of the cable drum 200 is sleeved on the periphery of the limiting plate 131, as shown in fig. 7, the boss 132 is correspondingly disposed on the outer side wall 131b of the limiting plate 131; if the cable drum 200 is placed in the first installation position, the boss 132 is correspondingly disposed on the inner sidewall 131a of the limiting plate 131.

Illustratively, the width of the boss 132 may be 1mm to 2mm, which is the relative distance between the side of the boss 132 remote from the limiting plate 131 and the side near the limiting plate.

In one example, the first cable inlet 1111 may also be disposed outside the limiting plate 131 away from the limiting plate 131. In another example, if the first cable inlet 1111 is circular or square, the limiting plates 131 may be disposed at the periphery of the first cable inlet 1111, and the optical cable on the cable tray 200 sleeved at the periphery of the limiting plates 131 may pass through the first cable inlet 1111 through the gap between two adjacent limiting plates 131; as shown in fig. 5 to 8, if the first cable inlet 1111 includes a circular hole and a fan-shaped hole, the limiting plate 131 may be disposed at the periphery of the circular hole, and the fan-shaped hole extends to the outer side of the limiting plate 131, and the cable tray 200 sleeved at the periphery of the limiting plate 131 may not shield the fan-shaped hole, so that the optical cable on the cable tray 200 may pass through the fan-shaped hole and exit the optical fiber storage box 100.

Based on the above example, in order to prevent the cable drum 200 from pressing the optical cable passing through the first cable inlet 1111 when the cable drum 200 is mounted on the first mounting assembly 130, as shown in fig. 6 and 7, at least two pad posts 150 may be provided on the base plate 111, the height of the pad posts 150 being smaller than the height of the limiting plate 131, and the pad posts 150 being used to support the cable drum 200 when the cable drum 200 is mounted on the first mounting assembly 130 such that a fiber routing space is formed between the bottom of the cable drum 200 and the base plate 111, so that the optical cable on the cable drum 200 passes through the first cable inlet 1111 through the fiber routing space, thereby preventing the cable drum 200 from extruding the optical cable.

Optionally, the limiting plate 131 is provided with a first fixing frame 133, and the first fixing frame 133 is used for fixing the optical cable passing through the first cable inlet 1111. The optical cable passing through the first cable inlet 1111 may be an optical cable on the cable tray 200, or may be another optical cable entering the accommodating cavity C from the first cable inlet 1111.

In one example, the first fixing frame 133 may be a bracket protruding on the limiting plate 131, and the optical cable passing through the first cable inlet hole 1111 may be fixed on the first fixing frame 133 by means of binding with a binding member, a binding band, or the like, or by winding the optical cable around the first fixing frame 133.

In another example, as shown in fig. 7, a first binding hole 1311 and a second binding hole 1312 are formed in the limiting plate 131, so that a first fixing frame 133 is formed between the first binding hole 1311 and the second binding hole 1312, and an optical cable passing through the first cable inlet hole 1111 may be fixed to the first fixing frame 133 by a fixing member such as a tie, a strap, or the like passing through the first binding hole 1311 and the second binding hole 1312.

Optionally, as shown in fig. 6 and 7, at least one first baffle 170 is further disposed on the bottom case 110, and the first baffle 170 is disposed on the periphery of the limiting plate 131. If the cable drum 200 is sleeved on the periphery of the limiting plate 131, the optical cable on the cable drum 200 is located between the limiting plate 131 and the first baffle 170, and the first baffle 170 can be used for limiting the position of the optical cable, so that the optical cable wound on the cable drum 200 is prevented from being ejected out of the optical fiber storage box 100 due to elasticity.

In this embodiment, the first baffle 170 may be disposed at an end of the peripheral edge 112 away from the bottom plate 111, or may be disposed at an inner side of the peripheral edge 112 facing the accommodating cavity C, or may be disposed at a side of the bottom plate 111 facing the box cover 120.

For example, assuming that the specification of the optical fiber storage box 100 provided in the embodiment of the present application is 86 boxes, the bottom plate 111 is square, and the surrounding edges 112 are distributed in a square shape, one first baffle 170 may be disposed at one end of the surrounding edge 112, which is far away from the bottom plate 111, and multiple first baffles 170 may be disposed at intervals, or one first baffle 170 may be disposed at one end of the surrounding edge 112, which is far away from the bottom plate 111, and distributed in a part of directions, and multiple first baffles 170 may be disposed at intervals. For example, as shown in fig. 6 and 7, at least one first baffle 170 is disposed at one end of the peripheral edge 112, which is closer to the limiting plate 131 and is away from the bottom plate 111, specifically, one of the peripheral edges 112 is disposed with one first baffle 170, and the other peripheral edge 112 is disposed with two first baffles 170 at intervals.

Further, the thickness of the first baffle 170 is smaller than the thickness of the peripheral edge 112, which is the relative distance between the side wall facing away from the receiving chamber C and the side wall facing the receiving chamber C. If the first baffle 170 is disposed at the end of the surrounding edge 112 away from the bottom plate 111, the sum of the heights of the first baffle 170 and the surrounding edge 112 is smaller than the height of the accommodating cavity C and larger than the sum of the heights of the cable tray 200 and the cushion column 150; if the first baffle 170 is disposed on the inner side of the peripheral edge 112 facing the accommodating cavity C or on the side of the bottom plate 111 facing the lid 120, the height of the first baffle 170 is smaller than the height of the accommodating cavity C and greater than the sum of the heights of the cable tray 200 and the cushion column 150. The height of the receiving chamber C is a relative distance between a side of the bottom plate 111 facing the lid 120 and a side of the lid 120 facing the bottom plate 111, and the height of the first baffle 170 and the height of the peripheral edge 112 are a relative distance between an end facing the bottom plate 111 and an end facing the lid 120.

As shown in fig. 6 and 7, a first protrusion 171 and/or a first avoidance hole 172 are provided on a side wall of one or more first baffles 170 of the at least one first baffle 170 facing away from the accommodating cavity C, and a second avoidance hole 122 for corresponding to the first protrusion 171 and/or a second protrusion 123 for corresponding to the first avoidance hole 172 are provided on a side wall of the box cover 120. When the box cover 120 covers the bottom box 110, the first protrusion 171 is clamped with the second avoidance hole 122, and the first avoidance hole 172 is clamped with the second protrusion 123, so that the box cover 120 is clamped with the bottom box 110.

In another embodiment, as shown in fig. 5 to 8, at least one second cable inlet 1122 is further formed on the peripheral edge 112.

It can be appreciated that, in the optical fiber storage box 100 provided in this embodiment of the present application, not only the optical cable pipeline disposed on the wall surface can be connected through the first cable inlet 1111, so as to implement a wire routing manner of a dark wire, but also an open wire routing manner can be implemented through the second cable inlet 1122. For example, when the optical fiber storage box 100 is installed on a wall surface, if the cable drum 200 is installed on the first installation component 130 and the optical fiber cable is wound on the cable drum 200, one end of the optical fiber cable is led out of the optical fiber storage box 100 through the second cable inlet hole 1122 and is connected with an information box arranged in other rooms or outdoors in a line-laying manner, the optical fiber cable between the optical fiber storage box 100 and the information box leaks on the wall surface, and the optical fiber connector at the other end of the optical fiber cable is connected with the inner port 300b of the optical fiber adapter 300.

Optionally, as shown in fig. 8, the fill assembly 113 includes a fill column 1131, with both sides of the fill column 1131 facing the peripheral edge 112 being connected to the peripheral edge 112 by one or more connecting columns 1132.

Alternatively, as shown in fig. 5 and 7, the first side plate 141 may be disposed adjacent to a side of the peripheral edge 112 facing the accommodating cavity C, the height of the first side plate 141 is greater than that of the peripheral edge 112, a fifth protrusion 1413 is disposed on a side wall of the first side plate 141 facing away from the accommodating cavity C, and correspondingly, a hook 127 is disposed on a side wall of the lid 120 facing the accommodating cavity C, and when the lid 120 covers the bottom case 110, the hook 127 is engaged with the fifth protrusion 1413, so as to lock the lid 120 and the bottom case 110. Further, the first side plate 141 may be closely attached to a side of the peripheral edge 112 facing the receiving cavity C.

Further, as shown in fig. 5 and 7, a third clamping groove 1412 is formed on a side wall of the first side plate 141 facing away from the accommodating cavity C, a fifth protrusion 1413 is disposed at a side end of the third clamping groove 1412 away from the bottom plate 111, and when the hook 127 is clamped with the fifth protrusion 1413, an end of the hook 127 close to the bottom plate 111 is located in the third clamping groove 1412.
