Description

FTTR networking system

[0001] This application claims priority to Chinese patent application No. 202323278180.3, filed on November 30, 2023, and utility model name “FTTR networking system”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present disclosure relates to the technical field of gateway equipment, and in particular to an FTTR networking system. Background Art

[0003] With the development of communication technology, fiber optic transmission is increasingly used in communication systems, among which FTTR (Fiber to The Room) is an important part of the optical network. In the FTTR networking system, the main gateway, as an ONT (Optical Network Terminal), is connected to the OLT (Optical Line Termination) at the operator's office through the uplink optical port, and is connected to the ONU (Optical Network Unit) through the downlink optical port. Since the main gateway has only one downlink optical port, for scenarios where a single main gateway corresponds to multiple slave gateways, a splitter is usually used to split the light to achieve the connection between one main gateway and multiple slave gateways.

[0004] In the related art, the optical splitter is usually mounted on the wall separately with expansion screws, or placed on a table or other supporting carrier along with the main gateway. This method of installing the optical splitter separately causes the optical splitter to take up extra space and the cables from the main gateway to the optical splitter are very messy.

[0005] Summary of the Invention

[0006] The present disclosure provides an FTTR networking system, in which the optical splitter is connected to the back shell of the main gateway through a mounting structure, realizing the integrated installation between the optical splitter and the main gateway, reducing the installation difficulty of the main gateway and the optical splitter, and reducing the space occupied by the optical splitter.

[0007] The FTTR networking system includes a main gateway and an optical splitter;

[0008] The main gateway includes a first back shell and a first mounting structure, wherein the first mounting structure is connected to the first back shell;

[0009] The optical splitter includes a second mounting structure that cooperates with the first mounting structure to connect the optical splitter to the first back shell of the master gateway.

[0010] The solution shown in the present disclosure realizes the integrated installation of the optical splitter and the main gateway by providing mounting structures on each of the main gateway and the optical splitter, and connecting the optical splitter to the back shell of the main gateway through the cooperation between the mounting structures. Compared with the traditional wall-mounted installation method of the optical splitter, there is no need for additional on-site drilling and installation of the optical splitter, which reduces the difficulty of installing the optical splitter; and compared with the method of placing the optical splitter alone on the desktop, the space occupied by the optical splitter is reduced.

[0011] In a possible implementation, the main gateway further includes a first panel;

[0012] The optical splitter is shielded by the first panel, and the first panel is arranged opposite to the first back shell.

[0013] The solution shown in the present disclosure realizes concealed installation of the optical splitter by setting the optical splitter to be shielded by the first panel so that the optical splitter is not visible on the panel side of the main gateway, thereby improving the overall aesthetics of the main gateway and the optical splitter assembly.

[0014] In a possible implementation, the first mounting structure includes a pair of first buckles arranged opposite to each other, with a bayonet formed between the pair of first buckles;

[0015] The second mounting structure includes a pair of second buckles arranged opposite to each other, and the second buckles pass through the bayonet and are engaged with the first buckles.

[0016] The solution disclosed herein uses a first clip on the main gateway and a second clip on the optical splitter to achieve a snap-fit ​​connection, thereby connecting the optical splitter to the back side of the main gateway. This snap-fit ​​connection has a simple structure and is easy to assemble, thus helping to reduce the difficulty of installing the optical splitter.

[0017] In a possible implementation, at least one of the pair of first buckles and the pair of second buckles has a guiding slope, and the guiding slope is configured to guide the second buckle to pass through the buckle opening.

[0018] The solution shown in the present disclosure further reduces the difficulty of assembling the main gateway and the optical splitter by providing guiding inclined surfaces on the first and second clips that can provide a guiding function.

[0019] In a possible implementation, the first mounting structure includes a mounting hole, and the second mounting structure includes a connecting column.

[0020] The connecting post is inserted into the mounting hole and is engaged with the edge of the mounting hole to limit the movement of the optical splitter in a direction perpendicular to the first back shell.

[0021] The solution presented in this disclosure connects the optical splitter to the back of the main gateway via mounting holes on the main gateway and connecting posts on the optical splitter. The mounting holes and connecting posts are simple, easy to set up, and require minimal assembly, thus simplifying the installation of the optical splitter.

[0022] In a possible implementation, the mounting hole includes a first hole and a second hole that are connected to each other, and the diameter of the first hole is larger than the diameter of the second hole;

[0023] The connecting column includes a cap body portion and a connecting rod portion connected to each other, the outer diameter of the cap body portion is smaller than the aperture of the first hole and larger than the aperture of the second hole, and the outer diameter of the connecting rod portion is smaller than the aperture of the second hole;

[0024] The connecting rod portion is limited at an end of the second hole away from the first hole.

[0025] The solution presented in this disclosure employs a gourd-shaped mounting hole on the main gateway. When assembling the optical splitter, the connecting post on the optical splitter can be inserted through the larger first hole and then slid into the smaller second hole to achieve a snap-fit ​​connection between the connecting post and the mounting hole. This arrangement allows the connecting post to slide into the mounting hole, further simplifying the installation of the optical splitter.

[0026] In a possible implementation, the first mounting structure and the second mounting structure include one or the other of a magnetic member and a magnetic attraction member, respectively, wherein the magnetic member is magnetic and the magnetic attraction member can be attracted by the magnetic member;

[0027] The magnetic component and the magnetic attraction component are magnetically connected.

[0028] In the solution shown in this disclosure, the optical splitter is connected to the back side of the main gateway through a magnetic fit. The magnetic fit has a simple structure and is easy to assemble, which helps to reduce the difficulty of installing the optical splitter.

[0029] In a possible implementation, the optical splitter includes a second back shell.

[0030] The second mounting structure is fixed to the second back shell; or, the second mounting structure is at least a part of the second back shell.

[0031] The solution presented in this disclosure improves the overall aesthetics of the main gateway and splitter assembly by attaching a magnetic or magnetically attractive component to the second back shell of the splitter. This allows the splitter to be attached to the main gateway through the back shell, exposing the panel side of the splitter. Furthermore, the second mounting structure, which serves as the magnetic or attractive component, is directly integrated with the second back shell of the splitter, simplifying the installation of the splitter itself. For example, the second back shell of the splitter can be made of a material that can be magnetically attracted.

[0032] In a possible implementation, the first mounting structure includes a positioning column, and the second mounting structure includes a positioning hole;

[0033] The positioning post cooperates with the positioning hole to limit the movement of the beam splitter in a direction parallel to the first back shell.

[0034] The solution shown in the present disclosure can provide a limit in the direction parallel to the first back shell through the cooperation of the positioning column and the positioning hole, thereby improving the connection stability between the main gateway and the splitter; and the cooperation structure of the positioning column and the positioning hole can provide preliminary alignment when assembling the splitter, which helps to reduce the difficulty of installing the splitter.

[0035] In a possible implementation, the optical splitter includes an ear portion and a main body portion, the ear portion is connected to an edge of the main body portion, and the ear portion is arranged parallel to the first back shell;

[0036] The positioning hole is opened on the ear portion.

[0037] The solution shown in the present disclosure connects the ear to the edge of the main body so that the ear can be exposed relative to the main body. Therefore, when the splitter is assembled on the main gateway, the positioning hole opened in the ear is always visible to the user, which facilitates the alignment of the positioning hole with the positioning post, thereby helping to reduce the difficulty of installing the splitter.

[0038] In a possible implementation, the main gateway further has at least one wire-binding structure, which is connected to the first back shell and is used to limit the position of the optical fiber connected to the optical splitter.

[0039] The solution shown in the present disclosure provides a wire clamping structure at the back shell of the main gateway to fix the optical fiber connected to the splitter and hide it at the back side of the main gateway, thereby improving the overall aesthetics of the main gateway and the splitter assembly.

[0040] In a possible implementation, the main gateway includes a supporting foot, which is located on a bottom side of the main gateway and is used to support the main gateway and the optical splitter.

[0041] In the solution shown in the present disclosure, for the scenario where the optical splitter is hung on the back of the main gateway, the main gateway is placed vertically through support legs, which is less difficult to install than the wall installation method.

[0054] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0055] This embodiment relates to an FTTR networking system, in which the main gateway and the optical splitter can each be provided with an installation structure, and the optical splitter is connected to the back shell of the main gateway through the cooperation between the mounting structures, thereby realizing the integrated installation between the optical splitter and the main gateway, reducing the installation difficulty of the main gateway and the optical splitter, and reducing the space occupied by the optical splitter.

[0056] Figure 1 is a schematic diagram of the structure of an FTTR networking system provided by an exemplary embodiment of the present disclosure. As shown in Figure 1, the FTTR networking system includes a main gateway 1 and an optical splitter 2. The main gateway 1 includes a first back shell 11 and a first mounting structure 13, the first mounting structure 13 being connected to the first back shell 11. Correspondingly, the optical splitter 2 includes a second mounting structure 23, which cooperates with the first mounting structure 13 to connect the optical splitter 2 to the first back shell 11 of the main gateway 1. In one example, the main gateway 1 also includes a first panel 12 disposed opposite the first back shell 11. The first panel 12 and the first back shell 11 can be assembled together to form a housing cavity, within which the electronic components used to implement various functions of the main gateway 1 can be housed. Exemplarily, the first panel 12 and the first back shell 11 can be snap-fitted together. During use, the first panel 12 of the main gateway 1 can be oriented toward the user, while the first back shell 11, disposed opposite the first panel 12, can be concealed behind the first panel 12 to be invisible to the user. Therefore, after the optical splitter 2 is connected to the first back shell 11 of the main gateway 1 through the first mounting structure 13 and the second mounting structure 23 , a portion of the optical splitter 2 or the entire optical splitter 2 can be hidden behind the main gateway 1 .

[0057] As shown in Figures 1 and 11, the size of the optical splitter 2 can be smaller or even much smaller than that of the main gateway 1, and the optical splitter 2 can be basically set in the middle part of the first back shell 11 in the main gateway 1, so that the optical splitter 2 is shielded by the first panel 12.

[0058] In one example, the optical splitter 2 may include a second back shell 21 and a second panel 22 disposed opposite to each other. The optical splitter 2 may be connected to the first back shell 11 of the main gateway 1 via the second back shell 21, so that the second panel 22 of the optical splitter 2 may be exposed relative to the main gateway 1.

[0059] Since the optical splitter 2 is connected to multiple cables, as shown in FIG1 and FIG10 , the first back shell 11 of the main gateway 1 may further have at least one cable-locking structure 14 , which is used to limit the position of the optical fiber connected to the optical splitter 2 .

[0060] In one example, each cable-holding structure 14 may include a pair of opposing clamping plates, with a threading slot formed between the clamping plates for the optical fiber to pass through. Furthermore, the clamping plates may have a raised stopper at one end away from the first back shell 11. The two stoppers may be positioned close to each other, thereby forming a tightened notch to prevent the optical fiber from escaping the threading slot.

[0061] The optical splitter 2 is mounted on the back of the first back shell 11 of the main gateway 1. This optical splitter 2 may affect the wall-mounting of the main gateway 1. To this end, as shown in Figures 1 and 9, the main gateway 1 includes support legs 15, which are located on the bottom side of the main gateway 1 and are used to support the main gateway 1 and the optical splitter 2. In one example, the combination of the main gateway 1 and the optical splitter 2 can be vertically supported on a fixed carrier such as a desktop by the support legs 15. Of course, in other examples, additional fixed structures such as brackets can also be provided to achieve wall-mounting of the combination of the main gateway 1 and the optical splitter 2 on the wall.

[0062] In one example, the support leg 15 can be detachably or movably connected to the housing formed by the first back shell 11 and the first panel 12 of the main gateway 1. Alternatively, the support leg 15 can be integrally formed with the first back shell 11 or the first panel 12 as a base.

[0063] In this embodiment, the main gateway 1 and the optical splitter 2 can be connected together through a snap fit, a hanging hole fit, or a magnetic fit. The above three fitting methods can be used separately or in combination. For example, in addition to being connected through a snap fit, the main gateway 1 and the optical splitter 2 can also have mounting structures for achieving a hanging hole fit or a magnetic fit.

[0064] The structural features for achieving the snap fit are described below.

[0065] As shown in Figures 2, 3, and 4, the first mounting structure 13 includes a pair of oppositely disposed first clips 131, with a slot 1311 formed between the pair of first clips 131. The second mounting structure 23 includes a pair of oppositely disposed second clips 231, which pass through the slot 1311 and engage with the first clips 131.

[0066] In one example, a pair of first buckles 131 can be respectively disposed near the top and bottom of the first back shell 11, so that a bayonet 1311 can be formed between the pair of first buckles 131 along the height direction of the main gateway 1. A pair of second buckles 231 on the optical splitter 2 can also be disposed opposite each other along the height direction of the optical splitter 2, so that the optical splitter 2 can be vertically fixed to the rear side of the main gateway 1.

[0067] In another example, the pair of first clips 131 can be respectively located near two side portions of the first back shell 11 arranged along the length direction, so that the pair of first clips 131 can be arranged opposite each other along the length direction of the main gateway 1. In this case, the pair of second clips 231 on the optical splitter 2 can be arranged opposite each other along the height direction of the optical splitter 2, or the second clips 231 can be arranged opposite each other along the length direction of the optical splitter 2, so that the optical splitter 2 can be fixed laterally to the rear side of the main gateway 1. This embodiment does not limit the fixing direction of the optical splitter 2 to the first back shell 11 of the main gateway 1.

[0068] In this embodiment, when the user is using the main gateway 1 normally, the portion of the main gateway 1 closer to the user's body can be considered the "bottom," while the portion farther from the user's body can be considered the "top." For example, when the main gateway 1 or optical splitter 2 is wall-mounted or supported vertically on a table, the vertically upper portion can be considered the "top," while the vertically lower portion can be considered the "bottom." The "side" portion refers to the portion extending between the top and bottom.

[0069] As shown in Figures 3 and 4, the first clip 131 can be formed into a hook shape, which includes a connecting portion and a hook portion connected to each other, wherein the connecting portion is used to connect to the first back shell 11 of the main gateway 1. The two hook portions in a pair of first clips 131 can be arranged opposite to each other and close to each other to form a bayonet 1311 between the two hook portions, and a receiving space for accommodating the second clip 231 is formed between the two opposite connecting portions. Similarly, the second clip 231 can also be formed into a hook shape, and the hook portion in the second clip 231 can pass through the bayonet 1311 to abut against the first clip 131, while the connecting portion in the second clip 231 can be located outside the bayonet 1311 and connected to the second back shell 21 of the optical splitter 2.

[0070] When assembling the optical splitter 2 with the main gateway 1, the optical splitter 2 is moved near the first back shell 11 of the main gateway 1, and the second snap fastener 231 on the optical splitter 2 is substantially aligned with the first snap fastener 131 on the main gateway 1, so as to be moved through the slot 1311. When passing through the slot 1311, the second snap fastener 231 can be squeezed and deformed by the corresponding first snap fastener 131. After the second snap fastener 231 passes through the slot 1311, the first snap fastener 131 can recover its elastic deformation and abut against the first snap fastener 131 under the action of the recovery force.

[0071] Since the second buckle 231 elastically deforms while passing through the bayonet 1311, this may hinder the user from moving the beam splitter 2. To address this issue, a guide slope can be provided on at least one of the pair of first buckles 131 and the pair of second buckles 231 to guide the second buckle 231 through the bayonet 1311.

[0072] In one example, each first buckle 131 and each second buckle 231 may be provided with a guide bevel. As shown in FIG4 , the guide bevel in the first buckle 131 (hereinafter referred to as the first guide bevel 1312) may be tilted so that the further away from the first back shell 11, the further away from the outside of the other first buckle 131, so that the bayonet 1311 is formed into a trumpet shape, thereby facilitating the second buckle 231 in the spectrometer 2 to pass through the bayonet 1311. The tilt direction of the guide bevel in the second buckle 231 (hereinafter referred to as the second guide bevel 2311) may be consistent with the tilt direction of the first guide bevel 1312. In other words, the second guide bevel 2311 may be tilted so that the further away from the second back shell 21, the further away from the other second buckle 231. When the second buckle 231 passes through the bayonet 1311, the first guide bevel 1312 and the second guide bevel 2311 may slide against each other.

[0073] 3 and 4 , the structures of the first and second clips 131, 231, can be seen to limit the movement of the optical splitter 2 in a direction perpendicular to the first back shell 11, for example, limiting the movement of the optical splitter 2 along the thickness direction of the main gateway 1. However, when the optical splitter 2 shakes or moves in a direction parallel to the first back shell 11, the first and second clips 131, 231 may become disengaged.

[0074] 2 , the first mounting structure 13 may further include a positioning post 134 ; the second mounting structure 23 may include a positioning hole 2341 . The positioning post 134 cooperates with the positioning hole 2341 to limit the movement of the optical splitter 2 in a direction parallel to the first back shell 11 .

[0075] In one example, the positioning post 134 may be a cylindrical column protruding relative to the first back shell 11, and correspondingly, the positioning hole 2341 may be a circular hole. The outer diameter of the positioning post 134 may be substantially the same as the aperture of the positioning hole 2341, or slightly smaller than the aperture of the positioning hole 2341. When the optical splitter 2 and the main gateway 1 are assembled together, a portion of the positioning post 134 may extend into the positioning hole 2341 to limit the movement of the optical splitter 2 in a direction parallel to the first back shell 11.

[0076] In one example, the positioning posts 134 may be provided in pairs on the first back shell 11, and correspondingly, the positioning holes 2341 may be provided in pairs on the beam splitter 2. Furthermore, each positioning post 134 may be provided near the first buckle 131, so that when the user assembles the beam splitter 2, preliminary alignment may be performed based on the position of the positioning post 134.

[0077] As shown in FIG9 , the optical splitter 2 includes an ear portion 234 and a main body 24 . The ear portion 234 is connected to the edge of the main body 24 and can be arranged parallel to the first back shell 11 . A positioning hole 2341 is formed in the ear portion 234 so that the positioning hole 2341 can be exposed relative to the main body 24 of the optical splitter 2 .

[0078] In an example, the ear portion 234 may be connected to an edge of a side portion of the main body 24 , so that the positioning hole 2341 defined in the ear portion 234 may be exposed relative to the main body 24 of the beam splitter 2 .

[0079] Moreover, the ear portion 234 can be arranged close to the side of the second back shell 21 in the splitter 2, so that when the user holds the splitter 2 from the side of the second panel 22 of the splitter 2 and brings the second back shell 21 close to the first back shell 11 in the main gateway 1, the positioning column 134 on the first back shell 11 can cooperate with the positioning hole 2341 opened on the ear portion 234 earlier.

[0080] The structural features for achieving the hanging hole fit are described below.

[0081] As shown in Figures 5, 6 and 7, the first mounting structure 13 may include a mounting hole 132, and the second mounting structure 23 includes a connecting column 232; the connecting column 232 can be inserted into the mounting hole 132 and engaged with the edge of the mounting hole 132 to limit the movement of the splitter 2 in a direction perpendicular to the first back shell 11.

[0082] The mounting hole 132 can be a through hole opened on the first back shell 11, which penetrates the first back shell 11 along the thickness direction of the first back shell 11, so that after the connecting column 232 passes through the mounting hole 132, the connecting column 232 can be engaged with the edge of the mounting hole 132 to prevent the connecting column 232 from falling out through the mounting hole 132.

[0083] In one example, the connecting column 232 can be interference fit with the mounting hole 132. During the process of the connecting column 232 passing into the mounting hole 132, it will be squeezed and elastically deformed, and the part passing through the mounting hole 132 will recover the elastic deformation and engage with the edge of the mounting hole 132 under the action of the recovery force.

[0084] In another example, the mounting hole 132 can be a gourd-shaped hole, and the connecting post 232 can be slidably assembled with the mounting hole 132. As shown in Figures 6 and 7, the mounting hole 132 includes a first hole 1321 and a second hole 1322 that are connected, and the aperture of the first hole 1321 is larger than the aperture of the second hole 1322; the connecting post 232 includes a cap portion 2321 and a connecting rod portion 2322 that are connected, and the outer diameter of the cap portion 2321 is smaller than the aperture of the first hole 1321 and larger than the aperture of the second hole 1322, and the outer diameter of the connecting rod portion 2322 is smaller than the aperture of the second hole 1322; the connecting rod portion 2322 is limited to the end of the second hole 1322 away from the first hole 1321.

[0085] When the optical splitter 2 is assembled with the main gateway 1, the cap portion 2321 in the connecting column 232 can first be inserted into the larger first hole 1321, and drive the connecting rod portion 2322 to move together, so that the connecting rod portion 2322 also passes through the first hole 1321. The connecting column 232 can then slide from the first hole 1321 into the smaller second hole 1322. At this time, the connecting rod portion 2322 cooperates with the second hole 1322, and because the outer diameter of the cap portion 2321 is larger than the aperture of the second hole 1322, the cap portion 2321 cannot pass through the second hole 1322 and fall out, thereby limiting the movement of the optical splitter 2 in a direction perpendicular to the first back shell 11. Under the action of the weight of the optical splitter 2 itself, the connecting rod portion 2322 is limited to the end of the second hole 1322 away from the first hole 1321, so that the optical splitter 2 can be hung on the back side of the main gateway 1.

[0086] In one example, the connecting post 232 may be a protruding structure integrally formed with the second back shell 21 of the optical splitter 2, so that the connecting post 232 and the second back shell 21 are integrally formed. In another example, the connecting post 232 may be a hanging nail independent of the second back shell 21. The second back shell 21 may be provided with a mating hole for mating with the hanging nail.

[0087] Similar to the aforementioned snap-fit, when the optical splitter 2 and the main gateway 1 are fitted with hanging holes, the first mounting structure 13 may further include a first mounting structure 13 including a positioning post 134; and the second mounting structure 23 including a positioning hole 2341. The positioning post 134 cooperates with the positioning hole 2341 to restrict the movement of the optical splitter 2 in a direction parallel to the first back shell 11.

[0088] The structural features for achieving magnetic engagement are described below.

[0089] As shown in FIG8 , the first mounting structure 13 may include a magnetic member 133, and the second mounting structure 23 may include a magnetic member 233. The magnetic member 133 is magnetic, and the magnetic member 233 can be attracted by the magnetic member 133, and the magnetic member 133 and the magnetic member 233 are magnetically connected. For example, the magnetic member 133 may be a magnet, and the magnetic member 233 may be an iron block. In another example, the magnetic member 133 may be an electromagnetic component.

[0090] In another example, the first mounting structure 13 may include a magnetic member 233, and the second mounting structure 23 may include a magnetic member 133. That is, the first mounting structure 13 and the second mounting structure 23 include one and the other of the magnetic member 133 and the magnetic member 233, respectively.

[0091] The magnetic member 233 can be integrally formed with the second back shell 21 of the optical splitter 2, such that the second mounting structure 23 is at least a portion of the second back shell 21. For example, the second back shell 21 can be made of a ferromagnetic material so that it can be attracted by the magnetic member 133 on the main gateway 1. Alternatively, the magnetic member 233 can be a separate component and fixed to the second back shell 21 by bonding or other means, thereby fixing the second mounting structure 23 to the second back shell 21.

[0092] Similar to the aforementioned snap-fit ​​and hanging hole fit, when the optical splitter 2 and the main gateway 1 utilize magnetic fit, the first mounting structure 13 may further include a first mounting structure 13 including a positioning post 134; and a second mounting structure 23 including a positioning hole 2341. The positioning post 134 cooperates with the positioning hole 2341 to restrict movement of the optical splitter 2 in a direction parallel to the first back shell 11. Of course, since the magnetic member 133 can more comprehensively and firmly fix the position of the magnetic member 233 during magnetic fit, the additional matching structure of the positioning post 134 and the positioning hole 2341 can be omitted when utilizing magnetic fit.
