Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of communication, in particular to a fiber connection box assembly, a fiber connection box and a cable tray. BACKGROUND

[0002] The fiber connection box is used for connecting with optical fiber or optical cable. In some scenarios, the length of the optical cable connected by the fiber connection box is too long, and then the excess optical cable needs to be coiled and connected with the fiber connection box. Therefore, the fiber connection box generally needs to be used with the cable tray. The cable tray is fixed on the wall, and the fiber connection box is fixed on the cable tray.

[0003] In the related art, the cable tray and the fiber connection box are assembled together by screws. However, the assembly efficiency is low, and the cost of the screws is increased. UTILITY MODEL CONTENT

[0004] The present disclosure provides a fiber connection box assembly, a fiber connection box and a cable tray. The fiber connection box and the cable tray are assembled together in a clamping manner, and the assembly efficiency is high. The technical solutions of the fiber connection box assembly, the fiber connection box and the cable tray are as follows.

[0005] In a first aspect, the present disclosure provides a fiber connection box assembly. The fiber connection box assembly includes a cable tray and a fiber connection box. The cable tray includes a support plate, and the support plate is provided with a plurality of first clamping structures arranged in a ring shape. The fiber connection box includes a back plate, and the back plate is provided with a recess and a plurality of second clamping structures. The plurality of second clamping structures are located in the recess and arranged in a ring shape. The plurality of first clamping structures are used to extend into the recess and clamp the plurality of second clamping structures respectively. The fiber connection box is used to switch the first clamping structure and the second clamping structure between the clamping state and the separation state by rotating. The second clamping structure clamped by each first clamping structure can be replaced, so that the fiber connection box can be fixed on the cable tray in multiple postures.

[0006] The cable tray is used for coiling optical fiber or optical cable, and can also be referred to as a fiber tray. The fiber connection box is used for connecting optical fiber or optical cable, and can also be referred to as an optical cable connection box. The fiber connection box includes an access terminal box (ATB), a fiber access terminal (FAT) and a splitting and splicing closure (SSC), etc.

[0007] In the process of assembling the optical fiber connector box assembly, the plurality of second clamping structures are first staggered with the plurality of first clamping structures respectively, and then the optical fiber connector box is pressed to make the plurality of first clamping structures extend into the grooves. Then, the optical fiber connector box is rotated in one direction, and the plurality of second clamping structures clamps the plurality of first clamping structures respectively. When it is necessary to disassemble the optical fiber connector box, the optical fiber connector box is rotated in the other direction, and the second clamping structure is separated from the first clamping structure.

[0008] The technical scheme provided by the present disclosure first arranges a plurality of first clamping structures on the support plate of the cable tray and a plurality of second clamping structures on the back plate of the optical fiber connector box, so that the cable tray and the optical fiber connector box can be fixed together by the clamping of the first clamping structures and the second clamping structures. In this way, screws are saved, the assembly operation of the optical fiber connector box assembly is simplified, and the assembly efficiency is improved.

[0009] Secondly, the optical fiber connector box is switched between the clamping state and the separation state by rotation, which is convenient for the operator to exert force and avoids some dangers caused by plug-in clamping, such as the danger of falling and bumping of the operator at the moment of pulling out. It can also avoid pulling the cable tray off the wall together during disassembly of the optical fiber connector box. It can also avoid the clamping failure of the second clamping structure and the first clamping structure due to the influence of the self-weight of the optical fiber connector box after multiple disassemblies.

[0010] Thirdly, the back plate is provided with a groove, and the second clamping structure is arranged in the groove, so that the second clamping structure does not protrude from the surface of the back plate or has a small protruding length, which is beneficial to the separate use of the optical fiber connector box in some scenes, such as the separate wall mounting of the optical fiber connector box. Moreover, the groove can preliminarily limit the first clamping structure, which is beneficial to the assembly of the optical fiber connector box assembly by the operator.

[0011] Fourthly, since the second clamping structure clamped by the first clamping structure can be replaced, the optical fiber connector box can be fixed to the cable tray in multiple poses. Since the plurality of first clamping structures and the plurality of second clamping structures are arranged in a ring shape, the orientation of the interface part of the optical fiber connector box is different in each pose. In this way, after the cable tray is mounted on the wall, the optical fiber connector box can be separately disassembled and the pose of the optical fiber connector box can be adjusted, so that the fiber outlet direction (i.e. the orientation of the interface part) of the optical fiber connector box can be more in line with the actual application scene.

[0012] In one implementation, the plurality of first clamping structures are the same in structure and are uniformly arranged in a ring direction. And / or, the plurality of second clamping structures are the same in structure and are uniformly arranged in a ring direction. In this way, each first clamping structure can be clamped with any second clamping structure, so that the optical fiber connector box can be fixed to the cable tray in multiple poses.

[0013] In an implementation, the support plate comprises four first clamping structures, and the back plate comprises four second clamping structures. Each first clamping structure is capable of clamping any second clamping structure, so that the fiber optic connector box is capable of being fixed to the disc cable rack in four postures. The four postures can be postures in which the interface part of the fiber optic connector box faces downward, upward, leftward, and rightward, respectively. The four postures can be switched after the fiber optic connector box is rotated by 90° in one posture.

[0014] In an implementation, the back plate comprises a plurality of grooves arranged in a ring shape. The plurality of second clamping structures are respectively located in the plurality of grooves, and the plurality of first clamping structures are respectively used to extend into the plurality of grooves. In this way, during the assembly of the fiber optic connector box assembly, the plurality of first clamping structures can be aligned with the plurality of grooves, and then the fiber optic connector box is operated so that the plurality of first clamping structures extend into the plurality of grooves and are clamped with the second clamping structures in the grooves.

[0015] In an implementation, the grooves are ring grooves used to accommodate the plurality of second clamping structures and the plurality of first clamping structures.

[0016] In an implementation, the plurality of first clamping structures are further used to be rotationally connected with the side walls of the grooves. In this way, after the plurality of first clamping structures extend into the grooves, the fiber optic connector box can only be rotated or separated from the disc cable rack, and cannot be shaken, which is conducive to the clamping of the first clamping structures and the second clamping structures, and further conducive to the assembly of the fiber optic connector box assembly.

[0017] In an implementation, the first clamping structure comprises a first baffle, and the first baffle and the support plate comprise a first limiting groove. The second clamping structure comprises a second baffle, and the second baffle and the groove bottom comprise a second limiting groove. The first baffle is used to extend into the second limiting groove, and the second baffle is used to extend into the first limiting groove, so as to limit the first clamping structure and the second clamping structure in the axial direction.

[0018] In an implementation, one of the first baffle and the second baffle is provided with a protruding column, and the protruding column is used to be interference-fitted with the other one of the first baffle and the second baffle, so as to limit the first clamping structure and the second clamping structure in the circumferential direction.

[0019] In an implementation, one of the first clamping structure and the second clamping structure comprises a clamping strip, and the other one comprises a stop block. The clamping strip comprises a clamping hook, and the clamping hook is located on a rotation path of the stop block. In the process of rotating the fiber optic connector box in a first direction, the clamping hook passes over and hooks the stop block, so as to limit the first clamping structure and the second clamping structure in the circumferential direction. In the process of rotating the fiber optic connector box in a second direction, the clamping hook passes over the stop block and is separated from the stop block, so as to release the limitation of the first clamping structure and the second clamping structure in the circumferential direction.

[0020] In an implementation, the clamping strip comprises a first segment and a second segment. The first segment is connected to the back plate or the support plate, and the second segment is separated from the back plate or the support plate and is provided with a clamping hook. In this way, the second segment is deformed to drive the clamping hook to swing, so that the clamping hook can smoothly pass over the stop block.

[0021] In an implementation, the back plate is further provided with a plurality of guide structures, the guide structures are oppositely arranged with the second clamping structure in the ring direction, and one side of the guide structure facing the second clamping structure is a guide slope, which is used to guide the first clamping structure to extend into the space between the guide structure and the second clamping structure. Thus, the preliminary positioning of the fiber connection box and the cable tray is achieved.

[0022] In an implementation, the back plate further comprises a wall-mounted installation hole, and the grooves are arranged around the wall-mounted installation hole. In this way, the remaining area on the back plate is fully utilized to arrange the wall-mounted installation hole, so that the fiber connection box can be individually wall-mounted for use.

[0024] In an implementation, the cable tray further comprises a mounting plate and a cable tray barrel, one end of the cable tray barrel is connected to the mounting plate, and the other end is connected to the support plate. The cable tray is an injection molding part, and a plurality of injection molding holes corresponding to the first clamping structures are connected to the inside of the cable tray barrel.

[0025] In an implementation, the edges of the support plate comprise perforations, the perforations are used for the binding belt to pass through, and the binding belt is used to bundle the optical cable or the optical fiber. When the fiber connection box is fixed to the cable tray, at least one perforation is located on the outside of the fiber connection box. In this way, the binding belt can bundle the optical cable on the support plate through the perforations, thereby limiting the optical cable, avoiding the occurrence of optical cable disorder, and facilitating the stable connection of the optical cable and the fiber connection box.

[0026] In an implementation, the four edges of the support plate all comprise perforations. When the fiber connection box is fixed to the cable tray, the interface part of the fiber connection box shields the perforations of a corresponding edge, and the perforations of the other three edges are located on the outside of the fiber connection box. In this way, the optical fiber is conveniently limited in various postures of the fiber connection box.

[0072] With the gradual development of the optical distribution network (ODN) industry, the application of the fiber connection box is more and more widely. The fiber connection box can also be referred to as a cable connection box, which is used to connect with optical fibers or optical cables. The fiber connection box includes an access terminal box (ATB), a fiber access terminal (FAT), a splitting and splicing closure (SSC), and the like. The access terminal box can also be referred to as a fiber terminal box or a fiber distribution box. The splitting and splicing closure can also be referred to as a cable joint box.

[0073] Taking the access terminal box as an example, the access terminal box is used to split the downlink optical signals sent by the upper-level device and send them to multiple lower-level devices respectively, and combine the uplink optical signals sent by the multiple lower-level devices and send them to the upper-level device. Therefore, the access terminal box needs to connect the upper-level device and the lower-level device through optical cables or optical fibers. Generally, the optical connection between the access terminal box and the upper-level device is referred to as an optical cable, and the optical connection between the access terminal box and the lower-level device is referred to as an optical fiber. Since the distance between the access terminal box and the upper-level device is indefinite, in some scenarios, the length of the optical cable is too long, and then a cable reel is needed to coil the excess length of the optical cable. The cable reel can also be referred to as a fiber reel. The cable reel is installed on the wall, and the access terminal box is fixed on the cable reel.

[0074] In the related art, the cable reel and the access terminal box are assembled together by screws. However, the screw assembly method has the following technical problems.

[0075] Firstly, the screw assembly method has low assembly efficiency and increases the cost of the screws.

[0076] Secondly, in order to improve the aesthetics, the screws should not be exposed, so the screws are arranged on the back surface of the access terminal box (i.e., the surface connected to the cable reel). This makes it impossible to separately remove the access terminal box after the cable reel and the access terminal box are installed on the wall, because the screws are arranged on the back surface of the access terminal box. Therefore, the cable reel and the access terminal box need to be removed together, which is cumbersome. Alternatively, the screws are arranged on the front surface of the access terminal box, and a corresponding shielding member is arranged to shield the screws. However, this increases the structural complexity of the access terminal box, and when the access terminal box is removed, the shielding member needs to be removed first, which is also cumbersome.

[0077] Thirdly, after the cable reel and the access terminal box are installed on the wall, the posture of the access terminal box relative to the cable reel is determined, that is, the orientation of the interface part of the access terminal box (i.e., the fiber outlet direction) is determined. If it is necessary to adjust the posture of the access terminal box, the cable reel and the access terminal box need to be removed and the postures of the cable reel and the access terminal box need to be adjusted as a whole, which is also cumbersome.

[0078] In view of the above technical problems, the present embodiment provides an optical fiber connection box assembly. As shown in the drawings, the optical fiber connection box assembly comprises a cable tray 1 and an optical fiber connection box 2. The cable tray 1 comprises a support plate 13, which is connected to the back plate 21 of the optical fiber connection box 2 by clamping. Figures 1-7

[0079] The cable tray 1 is used for fiber or cable winding, and can also be referred to as a fiber tray. In some examples, as shown in the drawings, the cable tray 1 comprises a mounting plate 11 and a cable winding drum 12, one end of the cable winding drum 12 is connected to the mounting plate 11, and the other end is connected to the support plate 13. The cable winding drum 12 is used for winding optical fibers or optical cables. The mounting plate 11 is provided with a mounting hole 111 for a screw to pass through to realize the wall mounting of the cable tray 1. Figure 1 Figure 2

[0080] The optical fiber connection box 2 can be any box or case used for connecting optical fibers or optical cables. For example, ATB, FAT or SSC, etc.

[0081] The technical solution provided by the present embodiment simplifies the assembly and disassembly operations of the optical fiber connection box assembly by assembling the optical fiber connection box 2 and the cable tray 1 in a clamping manner, and improves the assembly and disassembly efficiency.

[0082] Next, the implementation of the clamping of the support plate 13 and the back plate 21 will be exemplarily described. In some examples, as shown in the drawings, the support plate 13 is provided with a plurality of first clamping structures 131 arranged in a ring shape (such as a circular ring shape). As shown in the drawings, the back plate 21 is provided with a plurality of second clamping structures 211 arranged in a ring shape (such as a circular ring shape). The plurality of first clamping structures 131 are respectively used for clamping the plurality of second clamping structures 211 to realize the clamping of the support plate 13 and the back plate 21. As shown in the drawings, the plurality of first clamping structures 131 can be located on the side of the support plate 13 away from the mounting plate 11. Figure 8 Figure 9 Figure 8

[0083] ​​​​​​In order to adjust the posture of the fiber optic connector box 2 after the cable tray 1 is installed on the wall without disassembling the cable tray 1. The embodiment of the present disclosure is provided that each first clamping structure 131 can be clamped with at least two different second clamping structures 211. That is, the second clamping structure 211 clamped by each first clamping structure 131 can be replaced. In this way, by changing the second clamping structure 211 clamped with each first clamping structure 131, the posture of the fiber optic connector box 2 can be adjusted. Wherein, since the first clamping structure 131 and the second clamping structure 211 are arranged in a ring shape, the orientation of the interface part 20 is different (as shown in Figures 3-6 ) under each posture of the fiber optic connector box 2. In this way, it is beneficial to adjust the fiber outlet direction of the fiber optic connector box 2. Wherein, the interface part 20 is used to connect the optical cable or optical fiber.

[0084] In some examples, as shown in Figure 8 , the structures of the plurality of first clamping structures 131 are the same and are uniformly arranged along the ring direction. In this way, each first clamping structure 131 can be clamped with any second clamping structure 211, so that the fiber optic connector box 2 can be fixed to the cable tray 1 in multiple postures. Of course, as shown in Figure 13 , the structures of the plurality of first clamping structures 131 can be slightly different, as long as each first clamping structure 131 can be clamped with any second clamping structure 211.

[0085] In other examples, as shown in Figure 9 , the structures of the plurality of second clamping structures 211 are the same and are uniformly arranged along the ring direction. In this way, each first clamping structure 131 can be clamped with any second clamping structure 211, so that the fiber optic connector box 2 can be fixed to the cable tray 1 in multiple postures.

[0086] In some examples, each first clamping structure 131 of the embodiment of the present disclosure can clamp any second clamping structure 211. In this way, assuming that the number of first clamping structures 131 and second clamping structures 211 is N, the fiber optic connector box 2 can be fixed to the cable tray 1 in N postures.

[0087] For example, the above N is 4, that is, the number of first clamping structures 131 and second clamping structures 211 is four, and the central angle between adjacent two first clamping structures 131 is 90°. Then the fiber optic connector box 2 can be fixed to the cable tray 1 in four postures.

[0088] Wherein, Figures 3-6 respectively show the schematic diagrams of the fiber optic connector box 2 in the first posture, the second posture, the third posture and the fourth posture. As shown in Figure 3 , in the first posture, the interface part 20 of the fiber optic connector box 2 faces downward. As shown in Figure 4As shown, in the second posture, the interface part 20 of the fiber optic connector box 2 faces right. As shown in Figure 5 As shown, in the third posture, the interface part 20 of the fiber optic connector box 2 faces up. As shown in Figure 6 As shown, in the fourth posture, the interface part 20 of the fiber optic connector box 2 faces left. Through the above arrangement, the interface part 20 of the fiber optic connector box 2 can face any direction of up, down, left and right, which is conducive to meeting the fiber outlet requirements of the fiber optic connector box 2 in various scenes.

[0089] The embodiments of the present disclosure do not limit the implementation manner of switching the first clamping structure 131 and the second clamping structure 211 between the clamped state and the separated state.

[0090] In some examples, one of the first clamping structure 131 and the second clamping structure 211 is a clamping slot, and the other is a clamping strip. For example, the second clamping structure 211 is a clamping slot, and the first clamping structure 131 is a clamping strip. Then, the first clamping structure 131 and the second clamping structure 211 are switched between the clamped state and the separated state by plugging and unplugging.

[0091] Among them, in the process of assembling the fiber optic connector box assembly, first, align the plurality of second clamping structures 211 with the plurality of first clamping structures 131 respectively, and then press the fiber optic connector box 2 so that the plurality of second clamping structures 211 clamp the plurality of first clamping structures 131 respectively, then the assembly of the fiber optic connector box assembly is completed. When it is necessary to disassemble the fiber optic connector box 2, operate the fiber optic connector box 2 so that the back plate 21 and the support plate 13 are away from each other, then the plurality of second clamping structures 211 are separated from the plurality of first clamping structures 131 respectively, and the disassembly of the fiber optic connector box 2 is completed.

[0092] In other examples, as shown in Figure 7 , Figure 10 and Figure 11 , the fiber optic connector box 2 is used to switch the first clamping structure 131 and the second clamping structure 211 between the clamped state and the separated state by rotating. Figure 10 and Figure 11 , only the first clamping structure 131 of the cable tray is retained.

[0093] In the process of assembling the fiber optic connector box assembly, as shown in Figure 10 and Figure 11 , first, make the plurality of second clamping structures 211 staggered with the plurality of first clamping structures 131 respectively, and then press the fiber optic connector box 2 so that each second clamping structure 211 extends into the interval between the adjacent two first clamping structures 131. Then, as shown in Figure 10 and Figure 11As shown, rotating the fiber optic connector box 2 in one direction, the plurality of second clamping structures 211 clamps the plurality of first clamping structures 131 respectively, and the assembly of the fiber optic connector box is completed. When it is needed to disassemble the fiber optic connector box 2, rotating the fiber optic connector box 2 in another direction, the second clamping structure 211 is separated from the first clamping structure 131. Then, the operator can operate the fiber optic connector box 2 to make the back plate 21 and the support plate 13 away from each other, and the disassembly of the fiber optic connector box 2 is completed.

[0094] The technical scheme provided by the embodiment of the present disclosure is that the fiber optic connector box 2 is arranged to switch the first clamping structure 131 and the second clamping structure 211 between the clamping state and the separation state by rotating. First, it is convenient for the operator to exert force, and some dangers caused by the plug-in and plug-out mode can be avoided, for example, the danger of falling and knocking of the operator at the moment of pulling out. Second, it can also avoid pulling the cable tray 1 off the wall together during the disassembly of the fiber optic connector box 2. Third, it can also avoid that the fiber optic connector box 2 is affected by the self-weight after being disassembled for many times, so that the second clamping structure 211 and the first clamping structure 131 are clamped invalidly.

[0095] In some examples, as shown in FIG. 1, Figure 9 As shown, the back plate 21 further includes a groove 210, the second clamping structure 211 is fixed in the groove 210, and the first clamping structure 131 is used to extend into the groove 210. In this way, on the one hand, the gap between the surface of the back plate 21 and the surface of the support plate 13 is reduced. On the other hand, the groove 210 can preliminarily limit the first clamping structure 131, which is beneficial to the operator to assemble the fiber optic connector box assembly. In addition, by arranging the second clamping structure 211 to be fixed in the groove 210, the second clamping structure 211 will not protrude from the surface of the back plate 21, or the protruding length is very small, which is beneficial to the separate use of the fiber optic connector box 2 in some scenarios, for example, the fiber optic connector box 2 is separately installed on the wall.

[0096] Of course, in other examples, the support plate 13 can also be arranged to include the groove 210, and the first clamping structure 131 is fixed in the groove 210, and the second clamping structure 211 is used to extend into the groove 210.

[0097] The embodiment of the present disclosure does not limit the form of the groove 210, and in some examples, as shown in FIG. 1, Figures 9-11 As shown, the groove 210 is a plurality of grooves, and the plurality of grooves 210 are arranged in a ring shape. Each groove 210 is used to accommodate one second clamping structure 211 and one first clamping structure 131. Among them, each first clamping structure 131 or second clamping structure 211 can extend into any groove 210, so that the fiber optic connector box 2 can be fixed to the cable tray 1 in multiple postures.

[0098] The technical scheme provided by the embodiments of the present disclosure is advantageous to the preliminary positioning of the fiber optic connector box 2 in the process of assembling the fiber optic connector box assembly. For example, the plurality of first clamping structures 131 can be aligned with the plurality of grooves 210 respectively, and then the fiber optic connector box 2 is operated so that the plurality of first clamping structures 131 respectively extend into the plurality of grooves 210 and are clamped with the second clamping structures 211 in the plurality of grooves 210 respectively. Alternatively, for the case that the grooves 210 are arranged on the support plate 13, the plurality of second clamping structures 211 can be aligned with the plurality of grooves 210 respectively, and then the fiber optic connector box 2 is operated so that the plurality of second clamping structures 211 respectively extend into the plurality of grooves 210 and are clamped with the first clamping structures 131 in the plurality of grooves 210 respectively.

[0099] In other examples, as shown in Figure 17 and Figure 18 , the groove 210 can also be an annular groove (circular ring groove), and the annular groove is used to accommodate the plurality of second clamping structures 211 and the plurality of first clamping structures 131. Each first clamping structure 131 can extend into the space between any two adjacent second clamping structures 211, so that the fiber optic connector box 2 can be fixed to the cable tray 1 in multiple attitudes.

[0100] In some examples, as shown in Figure 10 and Figure 18 , the plurality of first clamping structures 131 can also be rotatably connected with the side wall of the groove 210. In this way, after the first clamping structure 131 extends into the groove 210, the fiber optic connector box 2 can only rotate or be separated from the cable tray 1, and cannot be shaken, which is advantageous to the clamping of the first clamping structure 131 and the second clamping structure 211.

[0101] In some examples, as shown in Figure 10 and Figure 18 , the groove 210 includes an inner side wall and an outer side wall, and the inner side wall and the outer side wall are oppositely arranged and extend along the rotation direction. The plurality of first clamping structures 131 are attached to the inner side wall and / or the outer side wall to achieve the rotation connection of the first clamping structure 131 and the groove 210.

[0102] Of course, in other examples, the plurality of second clamping structures 211 can also be rotatably connected with the side wall of the groove 210.

[0103] In other examples, other structures can also be used to achieve the rotation connection of the back plate 21 and the support plate 13. For example, one of the back plate 21 and the support plate 13 is provided with a circular table, and the other is provided with a circular groove. The circular table extends into the circular groove and is attached to the side wall of the circular groove to achieve the rotation connection of the back plate 21 and the support plate 13.

[0104] In some examples, as shown inFigures 9-11 As shown, a guide structure 215 is provided in the groove 210. The guide structure 215 is arranged opposite to the second snap-fit ​​structure 211, and the side of the guide structure 215 facing the second snap-fit ​​structure 211 is a guide slope. The guide slope is used to guide the first snap-fit ​​structure 131 to be inserted between the guide structure 215 and the second snap-fit ​​structure 211, so as to achieve the initial positioning of the optical fiber connector box 2 and the cable tray 1.

[0105] In some examples, such as Figure 7 , Figure 8 , Figure 13 and Figure 14 As shown, four indicator marks 137 are provided on the support plate 13 of the cable tray 1. The indicator marks 137 are elongated. Figure 7 As shown, when the four edges of the fiber optic connector 2 are parallel to the four indicator marks 137, and the four indicator marks 137 surround the fiber optic connector 2, the multiple second snap-fit ​​structures 211 of the fiber optic connector 2 can extend into the groove 210. Then, by rotating the fiber optic connector 2, the first snap-fit ​​structure 131 and the second snap-fit ​​structure 211 can be snapped together. The indicator marks 137 can be strip-shaped grooves or strip-shaped protrusions.

[0106] The implementation methods of the first snap-fit ​​structure 131 and the second snap-fit ​​structure 211 will be described below by way of example.

[0107] In some examples, such as Figure 8 and Figure 11 As shown, the first snap-fit ​​structure 131 includes a first baffle 132, and a first limiting groove 1320 is included between the first baffle 132 and the support plate 13. Figure 9 and Figure 11 As shown, the second snap-fit ​​structure 211 includes a second baffle 212, and a second limiting groove 2120 is included between the second baffle 212 and the back plate 21. Figure 11 As shown, the first baffle 132 extends into the second limiting groove 2120, and the second baffle 212 extends into the first limiting groove 1320 to limit the first snap-fit ​​structure 131 and the second snap-fit ​​structure 211 in the axial direction. When the back plate 21 and the support plate 13 tend to move away from each other, the back plate 21 and the support plate 13 cannot be separated due to the mutual obstruction of the first baffle 132 and the second baffle 212.

[0108] To achieve circumferential limiting of the first latching structure 131 and the second latching structure 211, in some examples, such as Figure 8 , Figure 10 and Figure 11 As shown, the first snap-fit ​​structure 131 includes a snap-fit ​​strip 133, and the snap-fit ​​strip 133 includes a snap hook 1330. For example... Figures 9-11As shown, the second locking structure 211 includes a stop 213. The hook 1330 is located on the rotation path of the stop 213.

[0109] like Figure 10 and Figure 11 As shown, during the rotation of the fiber optic connector 2 in the first direction, the hook 1330 passes over and engages with the stop 213, thereby limiting the first locking structure 131 and the second locking structure 211 in the circumferential direction. During the rotation of the fiber optic connector 2 in another direction, the hook 1330 passes over and disengages from the stop 213.

[0110] In some examples, such as Figure 10 As shown, a snap-fit ​​groove 2131 is formed between the stop 213 and one end wall of the groove 210. A hook 1311 is used to limit itself within the snap-fit ​​groove 2131, thereby limiting the first snap-fit ​​structure 131 and the second snap-fit ​​structure 211 in the circumferential direction. In other examples, such as... Figure 17 and Figure 18 As shown, the stop blocks 213 exist in pairs, and a snap-fit ​​groove 2131 is formed between two adjacent stop blocks 213. Each snap-fit ​​groove 2131 is used to limit a snap hook 1311 to achieve the circumferential limitation of the first snap-fit ​​structure 131 and the second snap-fit ​​structure 211.

[0111] In order for the hook 1330 to pass smoothly over the stop 213, in some examples, such as Figure 12 and Figure 11 As shown, the snap-fit ​​strip 133 includes a first segment 1331 and a second segment 1332. The first segment 1331 is connected to the support plate 13, and the second segment 1332 is separate from the support plate 13, and the second segment 1332 is provided with a snap hook 1330. This improves the deformation capability of the second segment 1332, making the snap hook 1330 easier to swing. Correspondingly, when the snap-fit ​​strip 1333 is located on the back plate 21, the first segment 1331 is connected to the back plate 21, and the second segment 1332 is separate from the back plate 21.

[0112] It should be noted that in some examples, such as Figure 8 As shown, each first snap-fit ​​structure 131 includes a first baffle 132 and a snap-fit ​​strip 133. In other examples, such as Figure 13 As shown, a portion of the first snap-fit ​​structure 131 may include a first baffle 132 and a snap-fit ​​strip 133, while another portion of the first snap-fit ​​structure 131 may only include the first baffle 132. Wherein, because Figure 13 The fiber optic connector 2 corresponding to the cable tray 1 shown is still... Figure 9 The fiber optic connector 2 shown, that is, each second snap-fit ​​structure 211 of the fiber optic connector 2 includes a second baffle 212 and a stop block 213. Therefore, Figure 13Each first clamping structure 131 of the shown disc cable rack 1 can still be clamped with any second clamping structure 211.

[0113] In some other examples, as shown in Figure 14 all the first clamping structures 131 do not include the clamping strip 133. Correspondingly, as shown in Figure 15 the second clamping structure 211 does not include the stop block 213. In order to achieve the same circumferential limiting of the first clamping structure 131 and the second clamping structure 211, in some examples, as shown in Figure 16 the side of the first stop plate 132 facing the second stop plate 212 is provided with a protruding column 1321, which is used for interference fit with the second stop plate 212 to achieve the circumferential limiting of the first clamping structure 131 and the second clamping structure 211.

[0114] Of course, in some other examples, the side of the second stop plate 212 facing the first stop plate 132 can be provided with a protruding column, which is used for interference fit with the first stop plate 132 to achieve the circumferential limiting of the first clamping structure 131 and the second clamping structure 211.

[0115] Next, the positions of the first clamping structure 131 and the second clamping structure 211 are exemplarily described. In some examples, the disc cable rack 1 is an injection molding part, and in order to simplify the mold required for injection molding, as shown in Figure 19 the injection molding holes 135 corresponding to the plurality of first clamping structures 131 are communicated with the inside of the disc cable barrel 12. In this way, it is beneficial for the injection molding of the first clamping structure 131.

[0116] In some scenarios, the optical fiber connection box 2 does not need to be connected with the disc cable rack 1, but is used alone on the wall. In order to facilitate the optical fiber connection box 2 to be used alone on the wall, as shown in Figure 9 and Figure 15 the back plate 21 further includes a wall hanging installation hole 214 for the wall hanging screw to pass through. Since the back plate 21 is provided with a plurality of second clamping structures 211 and grooves 210, the area of the back plate 21 where the wall hanging installation hole 214 can be arranged is reduced. The embodiment of the present disclosure arranges the plurality of second clamping structures 211 around the wall hanging installation hole 214, that is, the wall hanging installation hole 214 is arranged at the center position of the plurality of second clamping structures 211, so as to fully utilize the remaining area of the back plate 21 to arrange the wall hanging installation hole 214.

[0117] In addition, in order to prevent the optical fiber connection box 2 from shaking after being hung on the wall, as shown in Figure 9 and Figure 15As shown, two wall mounting holes 214 are generally provided on the back plate 21. One of the wall mounting holes 214 is located at the center of the plurality of second clamping structures 211. The other wall mounting hole 214 is located at the edge of the back plate 21, for example, at the edge of the back plate 21 corresponding to the interface portion 20.

[0118] In some examples, as shown in FIG. 1, the support plate 13 is provided with an opening 134 for the fingers of an operator to pass through to facilitate the operator to operate the fiber disc. Figure 19

[0119] In order to position the optical cable, in some examples, as shown in FIG. 1, the edge of the support plate 13 includes a through hole 136 for a strap to pass through, the strap being used to bundle the optical fiber. When the fiber optic connector box 2 is fixed to the cable disc rack 1, at least one through hole 136 is located outside the fiber optic connector box 2. In this way, the strap bundles the optical cable connected to the fiber optic connector box 2 through the through hole 136 on the support plate 13, and the optical cable is positioned. Figures 1-6

[0120] In some examples, as shown in FIG. 1, the four edges of the support plate 13 each include a through hole 136. In this way, it is convenient to position the optical fiber in each attitude of the fiber optic connector box 2. Figure 1 Figures 2-6

[0121] In some examples, as shown in FIG. 1, the four edges of the support plate 13 each include a through hole 136. In this way, it is convenient to position the optical fiber in each attitude of the fiber optic connector box 2. Figures 3-6

[0122] The above description is only an optional embodiment of the present disclosure, and is not intended to limit the present disclosure. Any modification, equivalent replacement, improvement, etc. made within the principles of the present disclosure shall be included in the protection scope of the present disclosure.​​​​​
