[0042] In the description of the application, the description of the terms "one embodiment", "some embodiments", "exemplary embodiment", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the application. In the description, the exemplary description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0043] Referring to FIG. 1 and FIG. 2, in the embodiment of the application, a fiber distribution device is provided, which comprises a mounting plate 100, a mounting assembly 200 and a distribution box 300. The distribution box 300 can be different types of fiber modules that provide fusion of optical fibers and optical fibers, fusion of optical fibers and pigtail fibers, and exchange of optical connectors, and provide mechanical and environmental protection for optical fibers and their components. The distribution box 300 is mounted on the mounting plate 100 through the mounting assembly 200, so that the protection position of the distribution box 300 is stable during use.

[0044] The surface of one side of the mounting plate 100 forms a mounting surface 110, and the mounting assembly 200 is connected to the mounting surface 110. The mounting assembly 200 is arranged in a plurality of first directions, and each mounting assembly 200 comprises two mounting members 210 spaced apart in the first direction, and the two mounting members 210 define a mounting slot 220 extending in a second direction. Referring to FIG. 3, the distribution box 300 comprises a first mounting portion 310 and a second mounting portion 320 arranged in the second direction. The length of the second mounting portion 320 in the first direction is greater than the length of the first mounting portion 310 in the first direction, that is, the width of the distribution box 300 at the second mounting portion 320 is greater than the width at the first mounting portion 310. The first mounting portion 310 is inserted into the mounting slot 220, and the opposite sides of the first mounting portion 310 in the first direction are respectively detachably connected to the two mounting members 210 in the same mounting assembly 200. The distribution box 300 can be mounted on the mounting surface 110 of the mounting plate 100 through the detachable connection of the first mounting portion 310 and the mounting member 210, and can be removed from the mounting plate 100 for further maintenance and replacement.

[0045] It can be understood that the mounting assembly 200 in the application is arranged at the rear end of the distribution box 300 in the second direction. Since the distribution box 300 itself has the characteristics of a wide front end and a narrow rear end, the gap between the adjacent first mounting portions 310 in the first direction provides mounting space for the mounting assembly 200. The distribution of the distribution box 300 and the mounting assembly 200 is relatively compact, effectively reducing the space occupied by the mounting assembly 200 between adjacent distribution boxes 300, so that the fiber distribution device can arrange a larger number of distribution boxes 300 in the first direction, thereby improving the wiring density of the fiber distribution device.

[0046] The length ratio of the first mounting portion 310 to the second mounting portion 320 in the second direction is in the range of 1 / 3-2 / 3. On one hand, the first mounting portion 310 has sufficient length to connect with the mounting member 210, which increases the contact area of the first mounting portion 310 and the mounting member 210 and improves the connection strength of the distribution box 300. On the other hand, the installation assembly 200 occupies less space, which does not affect the fiber density of the fiber distribution box 300. On this basis, the length ratio of the first mounting portion 310 to the second mounting portion 320 in the second direction can be 1 / 3, 1 / 2, 2 / 5, 2 / 3, etc. In addition, after each mounting slot 220 is installed with the distribution box 300, the distance between the second mounting portions 320 of adjacent distribution boxes 300 is reduced. Further, the second mounting portions 320 of adjacent distribution boxes 300 can be attached to each other to improve the compactness of the distribution box 300 assembly and the wiring density of the fiber distribution equipment. Alternatively, the second mounting portions 320 of adjacent distribution boxes 300 can have a predetermined gap therebetween to provide sufficient installation space for the assembly of the distribution box 300, and the disassembly of adjacent distribution boxes 300 does not affect each other.

[0047] Further, at least one side of the second mounting portion 320 in the first direction protrudes compared to the same side of the first mounting portion 310, so that the width of the second mounting portion 320 is greater than the width of the first mounting portion 310. For example, one side of the mounting plate 100 in the first direction is defined as the left side, and the opposite side is defined as the right side. The left side of the second mounting portion 320 protrudes to the left relative to the left side of the first mounting portion 310, or the right side of the second mounting portion 320 protrudes to the right relative to the right side of the first mounting portion 310, or the left side of the second mounting portion 320 protrudes to the left relative to the left side of the first mounting portion 310, and the right side of the second mounting portion 320 protrudes to the right relative to the right side of the first mounting portion 310.

[0048] It should be noted that the above-mentioned "detachable connection" means that the first mounting portion 310 can be connected to the mounting member 210, and when in the connected state, the relative position between the first mounting portion 310 and the mounting member 210 is stable, and the connection between the first mounting portion 310 and the mounting member 210 can be released. After the connection between the two is released, the first mounting portion 310 can be separated from the mounting member 210, so that the distribution box 300 can be removed from the mounting plate 100, which facilitates the later maintenance of the distribution box 300. The detachable connection between the first mounting portion 310 and the mounting member 210 is not limited to clamping, threaded connection, plug-in connection, etc.

[0049] The first direction is the arrangement direction of the distribution box 300 on the mounting plate 100 and the interval direction of the two mounting members 210 in the same mounting assembly 200, and the second direction is the extension direction of the mounting groove 220, the first direction and the second direction are at a certain angle, that is, the first direction and the second direction are not parallel. In an embodiment, the first direction and the second direction are perpendicular, the first direction is arranged as the width direction of the fiber distribution equipment, and the second direction is arranged as the insertion direction of the cable and the distribution box 300.

[0050] The insertion direction of the first mounting part 310 into the mounting groove 220 can be arranged as the second direction or the third direction, the third direction is the thickness direction of the fiber distribution box 300, the mounting surface 110 is arranged as one side surface of the mounting plate 100 along the third direction, and the first direction, the second direction and the third direction are perpendicular to each other. For example, the side part of the two mounting members 210 in the same mounting assembly 200 away from the mounting surface 110 forms an opening, the first mounting part 310 is inserted into the mounting groove 220 along the third direction through the opening, and the first mounting part 310 inserted into the mounting groove 220 is detachably connected with the mounting member 210, so that the distribution box 300 is mounted on the mounting plate 100.

[0051] Alternatively, the two mounting members 210 in the same mounting assembly 200 form an opening at one end of the mounting groove 220 in the second direction, the second mounting part 320 is defined as located at the front part of the distribution box 300, the first mounting part 310 is located at the rear part of the distribution box 300, and the opening is located at the front part of the mounting groove 220, the first mounting part 310 is inserted into the mounting groove 220 from front to back along the second direction through the opening, and the first mounting part 310 inserted into the mounting groove 220 is detachably connected with the mounting member 210, so that the distribution box 300 is mounted on the mounting plate 100.

[0052] Referring to FIGS. 3-5, for the case that the first mounting part 310 is inserted into the mounting groove 220 along the second direction, the mounting member 210 is further provided with a first guide part 211 extending along the second direction, and the side part of the first mounting part 310 along the first direction is provided with a second guide part 311, the second guide part 311 is slidingly connected with the first guide part 211; during the insertion of the first mounting part 310 into the mounting groove 220, the second guide part 311 gradually moves along the second direction, and the second guide part 311 is guided by the first guide part 211 during the movement, the installation of the distribution box 300 to the mounting plate 100 is more stable, and the first mounting part 310 and the mounting member 210 are accurately matched, so as to ensure the stable connection of the first mounting part 310 and the mounting member 210.

[0053] In an embodiment, one of the first guide part 211 and the second guide part 311 is provided as a guide groove, and the other is slidably connected in the guide groove in the second direction. For example, the first guide part 211 is provided as a guide groove, and the second guide part 311 is slidably connected in the guide groove in the second direction. When the first mounting part 310 is inserted into the mounting groove 220, the groove wall of the guide groove restricts the movement direction of the second guide part 311, thereby guiding the movement of the first mounting part 310.

[0054] Further, the distance between the two first guide parts 211 in the same mounting assembly 200 gradually decreases in the direction from the second mounting part 320 to the first mounting part 310, and the length of the first mounting part 310 in the first direction gradually decreases in the direction from the second mounting part 320 to the first mounting part 310. Therefore, the front end opening of the mounting groove 220 is large, and the width of the front end of the first mounting part 310 is large, and the width of the rear end is small. When the first mounting part 310 is inserted into the mounting groove 220, the rear end of the first mounting part 310 can be easily inserted into the mounting groove 220 through the opening, and gradually moves to the rear end of the mounting groove 220 under the guidance of the first guide part 211, until the first mounting part 310 moves to the preset position in the second direction.

[0055] The first mounting part 310 is further provided with a guide surface 312 on both sides in the first direction. The two guide surfaces 312 are oppositely arranged, and each guide surface 312 faces the adjacent wiring box 300 in the first direction. The guide surface 312 is located on the side of the second guide part 311 away from the mounting surface 110, and the second guide part 311 protrudes relative to the guide surface 312. When the first mounting part 310 is inserted into the mounting groove 220 in the second direction, the side surface of the first guide part 211 in the first direction abuts against the guide surface 312, thereby guiding the movement of the first mounting part 310 and further improving the stability of the installation of the wiring box 300. Since the guide surface 312 is recessed relative to the second guide part 311, a space is provided for the first guide part 211, and the connection between the mounting assembly 200 and the wiring box 300 is more compact, the space utilization is high, and the wiring density of the fiber optic wiring device is improved.

[0056] In an embodiment, referring to FIGS. 3-5, the mounting part 210 is provided with a limiting surface 212 opposite to the mounting surface 110, and the side part of the first mounting part 310 in the first direction is provided with a limiting part 313 abutting against the limiting surface 212 in the third direction. The third direction is the thickness direction of the wiring box 300, and the first direction, the second direction and the third direction are perpendicular to each other. The limiting of the limiting part 313 by the limiting surface 212 enables the wiring box 300 to be stably mounted on the mounting plate 100 in the third direction.

[0057] Specifically, the mounting member 210 is provided with two limiting surfaces 212 spaced apart along the third direction, the limiting portion 313 abuts against the two limiting surfaces 212 respectively on the two opposite sides along the third direction, and the two limiting surfaces 212 provide opposite abutting actions to the limiting portion 313, so that the limiting portion 313 is clamped between the two limiting surfaces 212. Alternatively, in another embodiment, the mounting surface 110 is arranged opposite to the limiting surface 212, the surface of the first mounting portion 310 facing the mounting surface 110 abuts against the mounting surface 110, and the surface of the limiting portion 313 facing away from the mounting surface 110 abuts against the limiting surface 212, the first mounting portion 310 is subjected to opposite abutting actions from the mounting surface 110 and the limiting surface 212 respectively, and the contact area of the first mounting portion 310 with the mounting surface 110 is larger, so that the mounting surface 110 can provide stable support to the first mounting portion 310.

[0058] Further, the first guiding portion 211 is arranged spaced apart from the mounting surface 110, the first guiding portion 211 and the mounting surface 110 define a guiding groove, the surface of the first guiding portion 211 facing the mounting surface 110 forms the limiting surface 212, and the surface of the second guiding portion 311 facing away from the mounting surface 110 forms the limiting portion 313; during the plug-in process of the wiring box 300 to the mounting groove 220, the second guiding portion 311 is slidingly connected in the guiding groove, and the limiting portion 313 and the limiting surface 212 limit each other in the third direction, so that the wiring box 300 is simultaneously subjected to movement guiding and limiting in the third direction, and the mounting of the wiring box 300 to the mounting plate 100 is more stable.

[0059] Referring to Fig. 6, the mounting assembly 200 further comprises an elastic member 230, the first mounting portion 310 is provided with an abutting portion 314 on the side along the first direction, after the first mounting portion 310 is inserted into the preset position of the mounting slot 220, the elastic member 230 is clamped with the abutting portion 314 to limit the movement of the junction box 300 along the second direction, so that the junction box 300 is stably mounted in the preset position of the mounting slot 220, and the mounting of the junction box 300 to the mounting plate 100 is completed; in addition, the elastic member 230 can be deformed to enable the elastic member 230 to be clamped with the abutting portion 314 or to be separated from the abutting portion 314, when the elastic member 230 is clamped with the abutting portion 314, the abutting portion 314 is limited in the second direction by the elastic member 230, and the first mounting portion 310 is clamped by two elastic members 230 in the same mounting assembly 200 on both sides along the first direction, and is kept stable in the first direction, when the elastic member 230 is separated from the abutting portion 314, the limiting effect of the elastic member 230 on the abutting portion 314 is removed, and the junction box 300 can be removed from the mounting plate 100. Thus, by arranging the elastic member 230, the elastic member 230 is clamped with the abutting portion 314 or separated from the abutting portion 314 through deformation, and the detachable connection of the junction box 300 to the mounting plate 100 is realized, after the first mounting portion 310 is inserted into the mounting slot 220, the junction box 300 is simultaneously limited in the first direction and the second direction, and the mounting of the junction box 300 is more stable.

[0060] The elastic member 230 is arranged as a plastic structure capable of being deformed under force and having self-recovery capability, such as a spring plate, a spring, etc. The elastic member 230 can be integrally connected to the mounting member 210, or the elastic member 230 can be detachably connected to the mounting member 210, or the elastic member 230 is connected to the mounting plate 100.

[0061] Further, the first guiding portion 211 and the mounting surface 110 are arranged with a spacing therebetween and define a guiding slot, the second guiding portion 311 is slidingly connected in the guiding slot, and the elastic member 230 is arranged in the guiding slot, and the abutting portion 314 is arranged on the second guiding portion 311; thus, when the first mounting portion 310 is inserted into the mounting slot 220 along the second direction, the first guiding portion 211 and the second guiding portion 311 cooperatively guide the movement of the first mounting portion 310, during the movement of the first mounting portion 310, the second guiding portion 311 is limited by the limiting surface 212, and at the same time, the surface of the first mounting portion 310 keeps abutting with the mounting surface 110, and the junction box 300 keeps stable in the third direction, when the first mounting portion 310 moves to the preset position of the mounting slot 220, the elastic member 230 is clamped with the abutting portion 314, at this time, the first mounting portion 310 is limited in the first direction and the second direction by the elastic member 230, thus, the junction box 300 is simultaneously limited in the first direction, the second direction and the third direction, and the junction box 300 has high assembly stability.

[0062] It should be noted that the elastic member 230 and the limiting surface 212 are arranged in the guide groove, so that the connection between the components in the mounting assembly 200 is more compact, the space occupied by the mounting assembly 200 is reduced, and the wiring density of the fiber optic distribution equipment is increased. Meanwhile, the first mounting portion 310 is limited in multiple directions during the insertion into the mounting groove 220, so that the stable installation of the distribution box 300 to the mounting plate 100 is achieved.

[0063] It can be understood that the clamping mode of the elastic member 230 and the abutting portion 314 is not limited to that the elastic member 230 and the abutting portion 314 are provided with clamping hooks, and after the first mounting portion 310 is inserted into the preset position of the mounting groove 220, the elastic member 230 and the abutting portion 314 are clamped and limited in the first direction and the second direction. Alternatively, one of the elastic member 230 and the abutting portion 314 is provided with a recess, and the other is provided with a protrusion. When the first mounting portion 310 is inserted into the preset position of the mounting groove 220, the protrusion is clamped into the recess, and the elastic member 230 and the abutting portion 314 are limited in the first direction and the second direction.

[0064] Alternatively, in an embodiment, the abutting portion 314 has a groove 3141 on the side facing the elastic member 230, and part of the elastic member 230 protrudes towards the mounting groove 220 and forms a protruding portion 231. When the first mounting portion 310 is inserted into the preset position of the mounting groove 220, the protruding portion 231 is clamped into the groove 3141, and the groove 3141 in the second direction and the side portion 231 in the second direction abut, and the groove 3141 in the first direction and the side portion 231 in the first direction abut, so that the elastic member 230 and the abutting portion 314 are limited in the first direction and the second direction.

[0065] Further, the second guide portion 311 is provided with two parts that are discontinuous in the second direction, and the gap between the two parts forms the groove 3141.

The shape of the groove 3141 and the protruding portion 231 is matched to ensure that the protruding portion 231 and the groove 3141 have sufficient contact area. For example, the groove 3141 and the protruding portion 231 are both arranged in an arc shape, or the groove 3141 and the protruding portion 231 are both arranged in a triangular shape.

[0067] In addition, as shown in FIG. 3, the second mounting portion 320 is provided with an abutting surface 321 facing the end surface of the first mounting portion 310, the abutting surface 321 abutting the end portion of the mounting piece 210 in the first direction, and the abutting surface 321 and the abutting of the mounting piece 210 can assist the elastic piece 230 and the clamping of the abutting portion 314 to limit the distribution box 300 in the first direction, thereby improving the mounting accuracy of the distribution box 300.
