Description

Technical Field

[0001] This utility model relates to the field of optical communication equipment technology, and in particular to an optical cable terminal access device. Background Technology

[0002] Optical fiber terminal access devices are important equipment for terminal wiring in optical fiber transmission communication networks. They are mainly used for fixing optical fiber terminals, splicing optical cables and pigtails, and storing and protecting excess fiber.

[0003] In related technologies, fiber optic terminal access devices typically consist of a housing and a cover. The bottom wall of the housing houses accessories such as fiber optic trays and adapters. The problem is that because these accessories are fixed to the bottom wall, customers cannot flexibly adjust the positions or types of accessories within the device according to actual needs, thus limiting its applicability. Furthermore, when there are many accessories such as fiber optic trays and adapters, the area of ​​the bottom wall of the housing needs to be increased to expand its capacity. However, in practical applications, since fiber optic terminal access devices are usually installed on walls or columns, an excessively large bottom wall area is unsuitable for installation on small surfaces, further reducing its applicability.

[0042] This utility model proposes an optical cable terminal access device 1000.

[0043] Please see Figures 1 to 3In one embodiment of this utility model, the optical cable terminal access device 1000 includes an accessory. The optical cable terminal access device 1000 includes a housing 1 and a cover 2. The housing 1 has a receiving cavity 1a with a first opening 1b. The bottom wall of the receiving cavity 1a has a plurality of first mounting holes 1c arranged in an array. The cover 2 is hinged to the housing 1 and covers the first opening 1b. The side of the cover 2 facing the housing 1 has a mounting plate 3. The mounting plate 3 has a plurality of second mounting holes 3a arranged in an array. The accessory can be connected to the inner wall of any first mounting hole 1c or the inner wall of any second mounting hole 3a.

[0044] In this embodiment, the optical cable terminal access device 1000 includes a housing 1 and a cover 2. The housing 1 has a receiving cavity 1a with a first opening 1b. The cover 2 is hinged to the housing 1 and covers the first opening 1b. The cover 2 can be rotated to open or close the housing 1. When the housing 1 is closed, it provides temporary protection for the components and optical fibers inside the housing 1 and the cover 2. The cover 2 is connected to the housing 1 via an external hinge or via hinges formed on the cover 2 and the housing 1. The bottom wall of the receiving cavity 1a has a plurality of first mounting holes 1c arranged in an array. The first mounting holes 1c can be through holes or blind holes. A mounting plate 3 is provided on the side of the cover 2 facing the box 1. Optionally, the mounting plate 3 is arranged parallel to the bottom wall of the cover 2 and the bottom wall of the box 1, and is the same as the bottom wall of the receiving cavity 1a. The side of the cover 62 facing the box 1 is provided with a plurality of second mounting holes 3a arranged in an array. The accessories can be connected to the inner wall of any first mounting hole 1c or any second mounting hole 3a, so as to realize the installation of the accessories at any position of the box 1 or the cover 2 according to the actual use requirements, thereby improving the flexibility and applicability of the optical cable terminal access device 1000. Optionally, the mounting plate 3 and the cover 2 can be set as an integral molding structure. For example, the mounting plate 3 and the cover 2 can be connected by a connecting post, and the cover 2, the connecting post and the mounting plate 3 adopt a weldable structure. The cover 2, the connecting post and the mounting plate 3 are welded in sequence. Optionally, the mounting plate 3 and the cover 2 can also be set as a separate structure.

[0045] In the optical cable terminal access device 1000 proposed in this utility model, the accessories can be connected to the first mounting hole 1c or the second mounting hole 3a to be fixed in different positions inside the cover 2 or the box 1. Users can select accessories according to actual needs and freely install them into the cover 2 or the box 1, which improves the flexibility and applicability of the optical cable terminal access device 1000. In addition, the accessories that were originally set on the bottom wall of the box 1 can be adjusted to the cover 2, thereby reducing the area of ​​the bottom wall of the box 1, which is more conducive to installation on small areas of walls or columns, thus improving the flexibility and applicability of the optical cable terminal access device 1000.

[0046] Further, please refer to Figure 3 and Figure 4 In one embodiment of this utility model, the mounting plate 3 and the cover 2 are detachably connected to the side facing the box 1.

[0047] In this embodiment, in order to further improve the applicability and maintenance convenience of the mounting plate 3, the mounting plate 3 is detachably connected to the side of the cover 2 facing the box 1. This makes it convenient to replace the mounting plate 3. For example, mounting plates 3 of various shapes or mounting plates 3 with different densities of second mounting holes 3a can be replaced to meet different installation requirements.

[0048] Optionally, fixing holes can be provided on the accessory, and screws, bolts, or other fasteners can be used to screw the accessory to the first mounting hole 1c or the second mounting hole 3a, thereby fixing the accessory to the cover 2 or the box 1. This method can achieve a firm connection between the accessory and the mounting plate 3 with high reliability. Optionally, the connection between the mounting plate 3 and the cover 2 can also be achieved through snap-fit ​​structures such as clips. For example, clips can be provided on the cover 2, and snap-fit ​​holes can be provided on the mounting plate 3. The quick installation and removal of the mounting plate 3 and the cover 62 can be achieved through the snap-fit ​​engagement between the clips and the slots 61b. This method is quick, simple, and convenient.

[0049] Further, please refer to Figures 4 to 6 In one embodiment of the present invention, a plurality of first protrusions 11 are formed on the side of the box body 1 facing away from the cover body 2, and each first protrusion 11 is provided with a first mounting hole 1c, the first mounting hole 1c extending through the bottom wall of the box body 1 into the first protrusion 11; and / or, a plurality of second protrusions 31 are formed on the side of the mounting plate 3 facing away from the box body 1, each second protrusion 31 is provided with a second mounting hole 3a, the second mounting hole 3a extending through the bottom wall of the box body 1 into the second protrusion 31.

[0050] In this embodiment, fixing holes are provided on the accessory, and screws, bolts or other fasteners are used to screw the accessory to the first mounting hole 1c or the second mounting hole 3a, so as to fix the accessory to the cover 2 or the box 1. Considering that the first mounting hole 1c is located on the bottom wall of the receiving cavity 1a, i.e. the back plate of the box body 1, which is a plate structure, the plate structure itself is relatively weak. After multiple holes are opened, the load-bearing capacity of the plate structure is further weakened. In order to improve the load-bearing capacity and structural strength of the back plate of the box body 1, this embodiment forms multiple first protrusions 11 on the side of the box body 1 facing away from the cover 2. Each first protrusion 11 corresponds to a first mounting hole 1c. The first mounting hole 1c extends through the bottom wall of the box body 1 into the first protrusion 11. On the one hand, it increases the structural thickness of the periphery where the first mounting hole 1c is opened, thereby strengthening the structural strength and load-bearing capacity of the bottom wall of the receiving cavity 1a, making it easier to support more accessories. On the other hand, it increases the hole depth of the first mounting hole 1c, strengthens the connection strength between the fastener and the inner wall of the first mounting hole 1c, and improves the connection firmness between the accessories and the bottom wall of the receiving cavity 1a. Similarly, a plurality of second protrusions 31 are formed on the side of the mounting plate 3 facing away from the housing 1, and each second protrusion 31 corresponds to a second mounting hole 3a, which extends through the bottom wall of the housing 1 into the second protrusion 31. This improves the structural strength of the mounting plate 3 and the firmness of the connection between the mounting plate 3 and the accessories.

[0051] Further, please refer to Figure 3 and Figure 6 In one embodiment of the present invention, a plurality of cable management components 4 are provided around the periphery of the receiving cavity 1a. Each cable management component 4 includes a support column 41 and a first cable cantilever 42. The support column 41 is connected to the inner wall of the receiving cavity 1a, and the other end of the support column 41 is connected to the first cable cantilever 42. The first cable cantilever 42 extends along the side wall away from the receiving cavity 1a, and one end of the first cable cantilever 42 away from the side wall of the receiving cavity 1a is bent toward the bottom wall of the receiving cavity 1a.

[0052] In this embodiment, to organize the optical fibers within the housing 1 and prevent them from scattering and extending between the housing 1 and the cover 2, thus avoiding damage when the cover 2 is rotated to close the housing 1, multiple cable management components 4 are provided around the periphery of the receiving cavity 1a. For example, the receiving cavity 1a in this embodiment is square, with a cable management component 4 located at each of the four corners of the square. It is understood that this embodiment is merely an illustrative example, and the shape of the receiving cavity 1a, the number of cable management components 4, and the specific positions of the cable management components 4 around the periphery of the receiving cavity 1a can be adjusted according to actual needs; this embodiment does not impose any limitations.

[0053] Specifically, each cable management assembly 4 includes a support post 41 and a first cable cantilever 42. The support post 41 is connected to the inner wall of the receiving cavity 1a, and the other end of the support post 41 is connected to the first cable cantilever 42. It should be noted that the support post 41 can be connected to the bottom wall or the side wall of the receiving cavity 1a. The support post 41 can be configured as an integral structure with the housing 1, for example, by integral casting or welding. The first cable cantilever 42 extends along the side wall away from the receiving cavity 1a. Optionally, the first cable cantilever 42 can be configured to be perpendicular to the support post 41. To further enhance the constraint on the optical fiber within the cavity 1a, and to ensure that the optical fiber is laid along the periphery of the cavity 1a, the end of the first bundle cantilever 42 away from the side wall of the cavity 1a is bent toward the bottom wall of the cavity 1a. This constrains the optical fiber between the bent portion of the first bundle cantilever 42 and the side wall of the cavity 1a, preventing the optical fiber from scattering to the center of the cavity 1a and affecting the installation and adjustment of other accessories, and also preventing the optical fiber from being damaged by excessive bending curvature.

[0054] Further, please refer to Figures 1 to 4 In one embodiment of this utility model, the accessory includes a wire harness groove 5, which has a fastening hole 1000a and a receiving groove 5a. The wire harness groove 5 can be connected to the inner wall of any first mounting hole 1c or any second mounting hole 3a by a fastener adapted to the fastening hole 1000a. The wire harness groove 5 is also provided with a plurality of second wire harness cantilevers 51, the fixed end of each second wire harness cantilever 51 is connected to an inner side wall of the receiving groove 5a, and a wire harness space 51a is formed between the second wire harness cantilever 51 and the bottom wall of the receiving groove 5a.

[0055] In this embodiment, to facilitate the wiring and constraint of optical fibers, a cable tray 5 is provided that can mate with the first mounting hole 1c and the second mounting hole 3a. This tray can be straight or L-shaped to adapt to the internal shape of the housing 1 or the cover 2, such as... Figure 1 As shown. To facilitate fastening to the first mounting hole 1c or the second mounting hole 3a, the cable tray 5 is provided with fixing holes. Optionally, the fixing holes can be circular holes, or alternatively, they can be strip-shaped holes to improve installation flexibility and compatibility. The cable tray 5 has a receiving groove 5a for laying optical fibers. The cable tray 5 also has multiple second cable cantilever arms 51 for constraining the optical fibers within the receiving groove 5a. The fixed end of each second cable cantilever arm 51 is connected to an inner sidewall of the receiving groove 5a. A cable space 51a is formed between the second cable cantilever arm 51 and the bottom wall of the receiving groove 5a. Optionally, the second cable cantilever arm 51 can be configured to be parallel to the bottom wall of the receiving groove 5a.

[0056] Furthermore, please refer to Figure 1In one embodiment of the present invention, a plurality of second wire cantilever arms 51 are respectively disposed on the two inner sidewalls of the receiving groove 5a and are staggered; or, at least two second wire cantilever arms 51 are respectively disposed on the two inner sidewalls of the receiving groove 5a and are aligned, and a wire-passing gap 51b is formed between the two opposing second wire cantilever arms 51.

[0057] In this embodiment, two methods for arranging the second bundle cantilever 51 are proposed. The first method involves placing multiple second bundle cantilever 51s on the two inner sidewalls of the receiving groove 5a in a staggered arrangement. The advantage of this arrangement is that the distance between each pair of second bundle cantilever 51s is relatively large, making it easier to insert the optical fiber into the receiving groove 5a from the outside. The second method involves placing at least two second bundle cantilever 51s on the two inner sidewalls of the receiving groove 5a in an aligned arrangement, with a wire-passing gap 51b formed between the two opposing second bundle cantilever 51s. The advantage of this arrangement is that the distance between the two opposing second bundle cantilever 51s is short, providing strong constraint. However, during installation, the optical fiber needs to be passed through the wire-passing gap 51b to insert it into the receiving groove 5a, and the operation is relatively cumbersome due to the relatively narrow wire-passing gap 51b. Thus, preferably, the second wire cantilever 51 can be set at both ends of the wire trough body 5 according to the second arrangement method, and the second wire cantilever 51 can be set in the middle section of the wire trough body 5 according to the first arrangement method, thereby taking into account both constraint force and ease of operation.

[0058] Further, please refer to Figure 6 , Figure 9 and Figure 10 In one embodiment of this utility model, the accessory further includes a fiber collector box 6 and a mounting component 7. The mounting component 7 is provided with a fastening hole 1000a. The mounting component 7 can be connected to the inner wall of any first mounting hole 1c or any second mounting hole 3a by a fastener adapted to the fastening hole 1000a. A first mating part is provided on the side of the mounting component 7 facing away from the bottom wall of the receiving cavity 1a, and a second mating part is provided on the outer wall of the fiber collector box 6. The first mating part and the second mating part are engaged. One of the first mating part and the second mating part is a quick-release buckle 71, and the other is a slot 61b. The quick-release buckle 71 is engaged with the inner wall of the slot 61b.

[0059] In this embodiment, to meet the requirements for fiber splitting and splicing, a fiber collector box 6 is provided to accommodate the splitter and splice tube. Considering the need for frequent operations inside the fiber collector box 6, to improve the convenience and speed of removing the fiber collector box 6 from the inner wall of the first mounting hole 1c or the second mounting hole 3a, this embodiment also provides a mounting component 7. The mounting component 7 is connected to the inner wall of the first mounting hole 1c or the second mounting hole 3a by fasteners, and the mounting component 7 is connected to the fiber collector box 6 by a snap-fit ​​structure that allows for quick disassembly and assembly. Specifically, the mounting component 7 is provided with a fastening hole 1000a, and the mounting component 7 can be connected to the inner wall of either the first mounting hole 1c or the inner wall of either the second mounting hole 3a by fasteners that are compatible with the fastening hole 1000a. The mounting component 7 has a first mating part on the side of its bottom wall facing away from the receiving cavity 1a, and the outer wall of the fiber optic junction box 6 has a second mating part. The first mating part and the second mating part are engaged. One of the first mating parts and the second mating part is a quick-release buckle 71, and the other is a slot 61b. The quick-release buckle 71 is engaged with the inner wall of the slot 61b. Optionally, the quick-release buckle 71 can be a cantilever, claw, or curved buckle, and the slot 61b can be adapted to the quick-release buckle 71. Alternatively, the quick-release buckle 71 can also be a self-locking buckle. After pressing once, the self-locking buckle locks with the slot 61b, and after pressing again, the self-locking buckle unlocks from the slot 61b. In this way, the fiber optic junction box 6 can be set at any position inside the box body 1 or the cover body 2 through the mounting component 7, and the fiber optic junction box 6 can be quickly assembled and disassembled with the mounting component 7, which improves the convenience of operating the junction box and enriches the functions of the optical cable terminal access device 1000.

[0060] Furthermore, please refer to Figure 6 , Figure 9 and Figure 10 In one embodiment of the present invention, the quick-release buckle 71 has an elastic cantilever section 711, and a barb 712 is formed at the free end of the elastic cantilever section 711; an inclined section 611 is provided on one side wall of the slot 61b, and the barb 712 is engaged with the inclined section 611.

[0061] In this embodiment, to further improve the ease of assembling and disassembling the quick-release buckle 71 and the slot 61b, the quick-release buckle 71 has an elastic cantilever section 711, and a barb 712 is formed at the free end of the elastic cantilever section 711. The barb 712 can engage with the inner wall of the slot 61b. The elastic cantilever section 711 can be made of polypropylene or polycarbonate, and the elastic cantilever and barb 712 can be integrally formed with the mounting component 7 or the fiber collector box 6. When the elastic cantilever is installed in the fiber collector box 6, it is necessary to ensure that the mounting component 7 has sufficient thickness to accommodate the slot 61b. When the elastic cantilever is installed on the mounting component 7, optionally, the slot 61b can be provided on the outer wall of the fiber collector box 6. Preferably, an opening can be provided on the bottom wall of the fiber collector box 6, and a protruding rib can be provided on the side of the opening facing the inside of the fiber collector box 6. A slot 61b adapted to the quick-release buckle 71 is provided on the protruding rib. In this way, the slot 61b and the quick-release buckle 71 can be hidden inside the fiber collector box 6, reducing the risk of damage to the quick-release buckle 71 and improving the aesthetics. Specifically, one side wall of the slot 61b is provided with an inclined section 611, and the barb 712 engages with the inclined section 611. It should be noted that the purpose of providing the inclined section 611 is to reduce the obstruction between the side wall of the slot 61b and the barb 712 when disassembling the fiber collector box 6. That is, the inclined section 611 can guide the barb 712 and thus guide the elastic cantilever section 711 to deform in a direction away from the slot 61b, so that the barb 712 can disengage from the slot 61b, thereby reducing the obstruction between the side wall of the slot 61b and the barb 712, improving the convenience of disassembling the fiber collection box 6, and reducing the risk of damage to the elastic cantilever section 711.

[0062] Furthermore, please refer to Figure 10 In one embodiment of the present invention, the fiber collecting box 6 includes a bottom box 61 and a cover plate 62.
