[0001] This application claims priority to Chinese patent application filed on January 27, 2025, with application number 202520177825.4 and entitled "Fiber Optic Distribution Box", the entire contents of which are incorporated herein by reference. Technical Field
[0002] This application relates to the field of optical communication equipment technology, specifically to an optical fiber distribution box. Background Technology
[0003] Fiber optic distribution boxes provide fiber optic connectors for connecting optical fibers, enabling the extension and expansion of the fibers. They typically consist of a housing and a cover, which together form a cavity to house the optical fiber and a fiber optic plug located at one end of the fiber. Multiple fiber optic connectors are located on the inner wall of the housing, and the fiber optic plugs can be matched with the fiber optic connectors. The fiber optic plugs are located between the optical fiber and the fiber optic connectors, which makes it inconvenient to insert and remove the fiber optic plugs and connectors.
[0004] Utility Model Content
[0005] This application provides an optical fiber distribution box, which aims to increase the space for the optical fiber plug and optical fiber socket to be inserted and removed, thereby facilitating the insertion and removal of the optical fiber plug and optical fiber socket.
[0006] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:
[0007] On one hand, this application provides an optical fiber distribution box, which includes a first housing and a second housing. The first housing is provided with an optical fiber fixing structure, and the second housing is provided with a plurality of optical fiber ports. The first housing and the second housing are rotatably connected around a first axis.
[0008] The first housing and the second housing are in a snap-fit state during relative rotation; in the snap-fit state, the first housing and the second housing surround and form an accommodating space, the optical fiber fixing structure and the plurality of optical fiber jacks are all located in the accommodating space, and the optical fiber jacks face the optical fiber fixing structure.
[0009] The fiber optic distribution box provided in this application has a second housing with a first end and a second end; the first end of the second housing is rotatably connected to the first housing about a first axis, and the second end of the second housing is rotatably connected to the third housing about a second axis; the end of the third housing near the second housing has multiple fiber optic ports; the fiber optic ports face the side of the second housing and are used to connect fiber optic plugs; the fiber optic plugs are pluggable and detachable from the fiber optic ports along the insertion / removal direction; when the second housing rotates relative to the first housing and the third housing rotates relative to the second housing, the end of the third housing with the fiber optic ports can be exposed, expanding the space for the fiber optic plugs and fiber optic ports to be pluggable and detachable, thereby simplifying the operation on the fiber optic distribution box.
[0010] In some embodiments, the second housing includes a first part and a second part; the first part has a first end and a second end at its two ends in a first direction, the first end is rotatably connected to the first housing about the first axis, and the second end is rotatably connected to the second part about the second axis, the first axis and the second axis are both parallel to the second direction, and the second direction is perpendicular to the first direction; a plurality of optical fiber jacks are disposed at the end of the second part near the first part.
[0011] In some embodiments, the first portion includes a first shell plate parallel to both the first direction and the second direction; in the engaged state, the angle between the orientation direction of the fiber optic connector and the first shell plate is a first angle; the first portion and the second portion have an inserted / removed state during relative rotation, in which the angle between the orientation direction of the fiber optic connector and the first shell plate is a second angle; the second angle is greater than the first angle. This is so that after the second shell rotates relative to the first shell and the third shell rotates relative to the second shell, the end of the third shell with the fiber optic connector can be exposed.
[0012] In some embodiments, the first included angle is 0°-5°, and the second included angle is 30°-50°.
[0013] In some embodiments, the rotation angle of the second portion relative to the first portion is less than 50 degrees. This is to avoid excessive bending of the optical fiber connected to the optical fiber connector and to prevent the optical fiber from breaking.
[0014] In some embodiments, the first housing includes a second shell plate and a side plate, the second shell plate being parallel to the first axis; the side plate is erected on one side of the second shell plate and extends along the edge of the second shell plate; the first side plate is provided with a first opening and a second opening;
[0015] In the engaged state, the end of the first side plate away from the second shell plate contacts the second shell; the first opening and the second shell form a first cable passage hole, and the second opening and the second shell form a second cable passage hole; the first cable passage hole and the second cable passage hole communicate with the receiving space. With the above arrangement, the first cable passage hole and the second cable passage hole can be formed by the first shell and the third shell enclosing each other, facilitating the placement of the optical fiber within the first and second openings before the third shell and the first shell are engaged.
[0016] Furthermore, the fiber optic distribution box can accommodate multiple optical fibers simultaneously. Among these multiple optical fibers, some fibers enter the fiber optic distribution box through the first through-hole, while others enter through the second through-hole. This ensures that the fiber optic distribution box can accommodate multiple optical fibers while reducing the number of optical fibers allocated to each through-hole, thereby reducing the complexity of running multiple optical fibers through each through-hole.
[0017] In some embodiments, the first wire hole and the second wire hole are located on both sides of the first housing along the direction of the first axis, and both are located at the end of the first housing away from the first axis.
[0018] In some embodiments, the fiber optic distribution box includes a locking structure disposed on the first housing and the second housing, the locking structure being used to lock the first housing and the second housing in the engaged state.
[0019] In some embodiments, the locking structure includes a snap-fit structure, a magnetic structure, a rotary lock, or a flat lock.
[0020] In some embodiments, the optical fiber fixing structure includes a cable reel and a limiting member. The cable reel and the limiting member are both located on the same side of the second shell plate and are spaced apart. The cable reel and the limiting member are used to fix the optical fiber between the cable reel and the limiting member. The cable reel can serve as a carrier for winding the optical fiber, making it easier to store the optical fiber in the optical fiber distribution box.
[0021] In some embodiments, the first housing plate is further provided with mounting holes for installing connectors to fix the fiber optic distribution box. Attached Figure Description

[0034] Referring to Figure 1, in some embodiments, the fiber optic distribution box provides a fiber optic plug 10 for connecting the optical fiber, enabling the extension and expansion of the optical fiber. It includes a housing 20 and a cover plate 30, which together form a cavity for accommodating the optical fiber and the fiber optic plug 10 located at one end of the optical fiber. Multiple fiber optic ports 40 are provided on the inner wall of the housing, and the fiber optic plug 10 can be correspondingly connected to the fiber optic ports 40. The fiber optic plug 10 is located between the optical fiber and the fiber optic ports 40, making insertion and removal between the fiber optic plug 10 and the fiber optic ports 40 inconvenient.
[0035] Based on this, this application provides an optical fiber distribution box 100 to improve the above-mentioned problems.
[0036] Referring to Figures 2 and 3, the fiber optic distribution box 100 includes a first housing 110 and a second housing 120. One end of the first housing 110 is rotatably connected to one end of the second housing 120, so that the first housing 110 and the second housing 120 can rotate around a first axis. For example, the fiber optic distribution box 100 may include a first rotating shaft 131, the first axis being the central axis of the first rotating shaft 131, and the first rotating shaft 131 connecting one end of the first housing 110 and one end of the second housing 120.
[0037] The first housing 110 is provided with an optical fiber fixing structure 140, which is used to fix the optical fiber to the first housing 110. The second housing 120 is provided with an optical fiber socket 101, and one end of the optical fiber can be connected to the optical fiber socket 101 by means of an optical fiber plug 102. The first housing 110 and the second housing 120 are in a snap-fit state during relative rotation. In the snap-fit state, the first housing 110 and the second housing 120 enclose a receiving space, in which the optical fiber fixing structure 140, multiple optical fiber sockets 101, and the optical fiber plug 102 connected to the end of the optical fiber are all located, and the optical fiber socket 101 faces the optical fiber fixing structure 140. During the rotation of the first housing 110 and the second housing 120 around the first axis, the optical fiber socket 101 on the second housing 120 and the optical fiber fixed on the first housing 110 are relatively far apart, which increases the space for the optical fiber plug 102 and the optical fiber socket 101 to be inserted and removed, facilitating the insertion and removal of the optical fiber plug 102 and the optical fiber socket 101.
[0038] In the above embodiments, multiple fiber optic ports 101 may be provided, and the multiple fiber optic ports 101 are arranged at intervals or adjacent to each other along the direction of the first axis. The multiple fiber optic ports 101 may include one input port and a number of other output ports, the input port being used to connect to an input fiber optic cable, and the output ports being used to connect to an output fiber optic cable.
[0039] In the above embodiments, the second housing 120 may include a first portion 121 and a second portion 122. In the engaged state, the first portion 121 and the second portion 122 can be engaged at different positions on the same side of the first housing 110. In a first direction, the sum of the lengths of the first portion 121 and the second portion 122 is equal to the length of the first housing 110. In a second direction, the widths of the first portion 121 and the second portion 122 are both equal to the width of the first housing 110. This allows the first housing 110, the first portion 121, and the second portion 122 to enclose and form the aforementioned receiving space in the engaged state, wherein the first direction is perpendicular to the second direction. Furthermore, in a third direction, the thickness of the first portion 121 is the same as the thickness of the second portion 122, and the thickness of the first housing 110 is greater than the thicknesses of both the first portion 121 and the second portion 122, so that the optical fiber is primarily housed within the first housing 110, wherein the third direction is perpendicular to both the first and second directions.
[0040] In some embodiments, the two ends of the first portion 121 in the first direction are a first end 1211 and a second end 1212, respectively; the first end 1211 of the first portion 121 is rotatably connected to the first housing 110 about a first axis, the first axis being parallel to the second direction; for example, the fiber optic distribution box 100 may include a first rotating shaft 131, the first axis being the central axis of the first rotating shaft 131, the first rotating shaft 131 connecting one end of the first housing 110 in the first direction and the first end 1211 of the first portion 121, so that the first portion 121 can rotate outward relative to the first housing 110 about the first rotating shaft 131 to open the receiving space for receiving optical fibers.
[0041] The second end 1212 of the first part 121 is rotatably connected to the second part 122 about a second axis parallel to a second direction. For example, the fiber optic distribution box 100 may include a second rotating shaft 132, the second axis being the central axis of the second rotating shaft 132. The second rotating shaft 132 connects the second end 1212 of the first part 121 and one end of the second part 122 in a first direction, so that the second part 122 can rotate about the second rotating shaft 132 relative to the first part 121. The rotation direction of the second part 122 relative to the first part 121 is the same as the rotation direction of the first part 121 relative to the first housing 110.
[0042] The fiber optic connector 101 is located at the end of the second part 122 near the first part 121. The fiber optic plug 102 is pluggable and detachable from the fiber optic connector 101 along the insertion / removal direction (as shown by the dashed arrow in the figure), wherein the insertion / removal direction can be perpendicular to the second direction. After the first part 121 rotates relative to the first housing 110 and the second part 122 rotates relative to the first part 121, the end of the second part 122 with the fiber optic connector 101 can be exposed, which can also increase the space for the fiber optic plug 102 and the fiber optic connector 101 to be plugged and detached, facilitating the plugging and unplugging of the fiber optic plug 102 and the fiber optic connector 101.
[0043] Referring to Figures 4 and 5 in the above embodiments, the first part 121 includes a first shell plate 1213 parallel to both the first and second directions. When the fiber optic distribution box 100 is in the engaged state, the angle between the orientation direction of the fiber optic connector 101 (i.e., the insertion / removal direction of the fiber optic plug 102 relative to the fiber optic connector 101) and the first shell plate 1213 is a first angle A. The first part 121 and the second part 122 are in an insertion / removal state during relative rotation. In this state, the angle between the orientation direction of the fiber optic connector 101 and the first shell plate 1213 is a second angle B, where the second angle B is greater than the first angle A. This arrangement increases the space for insertion / removal of the fiber optic plug 102 and the fiber optic connector 101 after the first part 121 rotates relative to the first shell 110 and the second part 122 rotates relative to the first part 121, facilitating the insertion and removal of the fiber optic plug 102 and the fiber optic connector 101. For example, the first included angle A is 0°-5° and the second included angle B is 30°-50°.
[0044] In the above embodiment, the rotation angle of the second part 122 relative to the first part 121 is 0°-50°, so as to avoid excessive bending of the optical fiber connected to the optical fiber socket 101 and to prevent the optical fiber from breaking.
[0045] Referring to Figures 2 and 3 in the above embodiments, the position of the first housing 110 is fixed. In some embodiments, the first end 1211 of the first part 121 is connected to the right end of the first housing 110. The first part 121 then rotates clockwise around the first axis 131, and the second part 122 also rotates clockwise around the second axis 132. The end of the second part 122 closest to the first part 121 (i.e., the end with the fiber optic connector 101) is exposed in the space above the first part 121, facilitating the insertion and removal of the fiber optic plug 102 and the fiber optic connector 101. In other embodiments, the first end 1211 of the first part 121 can also be connected to the left end of the first housing 110. In this case, the first part 121 rotates counterclockwise around the first axis 131, and the second part 122 also rotates counterclockwise around the second axis 132. The resulting technical effect is the same as in the previous embodiment, and will not be elaborated further here.
[0046] In some embodiments, the fiber optic distribution box 100 further includes a first through hole 151 and a second through hole (not shown). Both the first through hole 151 and the second through hole are disposed on the first housing 110 and communicate with the receiving space for accommodating optical fibers. The fiber optic distribution box 100 can simultaneously accommodate multiple optical fibers. Among the multiple optical fibers, a portion of the optical fibers enter the fiber optic distribution box 100 through the first through hole 151, and another portion of the optical fibers enter the fiber optic distribution box 100 through the second through hole. This ensures that the fiber optic distribution box 100 can accommodate multiple optical fibers while reducing the number of optical fibers allocated to each through hole, thereby reducing the complexity of threading multiple optical fibers through each through hole.
[0047] In scenarios where the fiber optic distribution box 100 is installed on a wall, fiber optic cabling within a building is typically close to the ceiling. In the above embodiment, the first cable pass 151 and the second cable pass 151 are spaced apart along a second direction, and both the first cable pass 151 and the second cable pass 151 are located at the end of the first housing 110 away from the first rotating shaft 131. For example, when the fiber optic distribution box 100 is in the closed state, the first cable pass 151 and the second cable pass 151 are located at the top of the fiber optic distribution box 100, which allows the first cable pass 151 and the second cable pass 151 to be closer to the ceiling. With this arrangement, the extension direction of the optical fiber inside and outside the fiber optic distribution box 100 is approximately the same, reducing the number of times the optical fiber needs to be bent and lowering the damage rate of the optical fiber.
[0048] In the above embodiments, the first wire-passing hole 151 or the second wire-passing hole can be formed separately on the side wall of the first housing 110, or the first wire-passing hole 151 and the second wire-passing hole can be formed by the first housing 110 and the second part 122 together. For example, the first housing 110 includes a second housing plate 111 and a side plate 112. The side plate 112 is erected on one side of the second housing plate 111 and extends along the edge of the second housing plate 111. The second housing plate 111 is parallel to the first axis. In this embodiment, the second housing plate 111 is parallel to the first direction and the second direction. The side plate 112 is provided with a first opening 161 and a second opening 162, both of which are located at the end of the first housing 110 away from the first rotating shaft 131. The second part 122 includes a first baffle 171 and a second baffle 172. When the fiber optic distribution box 100 is in the fastened state, the first baffle 171 is engaged with the first opening 161. The size of the first baffle 171 is smaller than the size of the first opening 161, that is, the first baffle 171 cannot completely fasten the first opening 161, and the remaining part of the first opening 161 forms a first wire passage hole 151. Similarly, when the fiber optic distribution box 100 is in the fastened state, the second baffle 172 is engaged with the second opening 162. The size of the second baffle 172 is smaller than the size of the second opening 162, that is, the second baffle 172 cannot completely fasten the second opening 162, and the remaining part of the second opening 162 forms a second wire passage hole. With the above configuration, the first wire hole 151 and the second wire hole can be formed by the first housing 110 and the second part 122 enclosing each other. Before the second part 122 and the first housing 110 are fastened together, it is convenient to place the optical fiber in the first opening 161 and the second opening 162.
[0049] In some embodiments, the optical fiber fixing structure 140 includes a cable reel shaft 141 and a limiting member 142. Both the cable reel shaft 141 and the limiting member 142 are located on the same side of the second shell plate 111 and are spaced apart to fix the optical fiber between the cable reel shaft 141 and the limiting member 142. The central axis of the cable reel shaft 141 is arranged along a third direction, and the cable reel shaft 141 can serve as a carrier for winding the optical fiber, facilitating the storage of the optical fiber within the optical fiber distribution box 100. In conjunction with the above embodiments, if the first part 121 rotates outward around the first rotating shaft 131, the first part 121 can drive the second part 122 to separate from the first shell 110, exposing the space in the optical fiber distribution box 100 for accommodating the optical fiber, facilitating the winding of the optical fiber into the optical fiber distribution box 100 or the removal of the wound optical fiber from the optical fiber distribution box 100. For example, the first part 121 has a rotation angle of 0°-170° relative to the first housing 110. When the first part 121 rotates 170° relative to the first housing 110, the space for accommodating the optical fiber can be exposed to the greatest extent.
[0050] In some scenarios, it is necessary to fix the fiber optic distribution box 100, for example, to a wall surface. In this embodiment, the fiber optic distribution box 100 also includes mounting holes 180, which are disposed on the first housing plate. The mounting holes 180 are used to install connectors to fix the fiber optic distribution box 100. The connectors may include conventional connectors such as screws and bolts.
[0051] In some embodiments, the fiber optic distribution box 100 includes a locking structure 190 disposed on a first housing 110 and a second housing 120, and the locking structure 190 is used to lock the first housing 110 and the second housing 120 in a snap-fit state. The locking structure 190 includes a snap-fit structure, a magnetic structure, a rotating structure, or a planar lock, etc. Exemplarily, the locking structure 190 includes a mutually cooperating slot 191 and a snap-fit 192; in some embodiments, the slot 191 is disposed on the first housing 110, and the snap-fit 192 is disposed on the second portion 122, with the slot 191 and snap-fit 192 engaging when the fiber optic distribution box 100 is in a snap-fit state. In other embodiments, the slot 191 is disposed on the first housing 110, and the slot 191 is disposed on the second portion 122, with the slot 191 and snap-fit 192 engaging when the fiber optic distribution box 100 is in a snap-fit state.
[0052] In the above scenario, when the fiber optic distribution box 100 is in the closed state, the second part 122 is above the first part 121. After the first housing 110 and the second part 122 are connected, since the first end 1211 of the first part 121 is fixed to the first housing 110 and the second end 1212 of the first part 121 is fixed to the second part 122, the position of the first part 121 can also be fixed. When the fiber optic distribution box 100 is in the plugged-in state, the first housing 110 and the second part 122 are separated. Due to gravity, the first part 121 rotates relative to the first housing 110, exposing the receiving space of the fiber optic distribution box 100 for accommodating optical fibers.
[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of this application, and are not intended to limit them; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
