Description

Technical Field

[0001] The present disclosure relates to the field of optical communication technology, and in particular to an ONU device and an FTTR networking system. Background Art

[0002] The Passive Optical Network (PON) Optical Network Unit (ONU), also known as a PON ONU, is a core component in Fiber to the Room (FTTR) networking systems. The PON ONU is located at the user end and converts received optical signals into electrical signals, which are then transmitted to user devices such as computers, phones, or televisions.

[0003] The installation of PON ONU devices at the user end typically needs to comply with specific standards, some of which require embedded installation for convenient use in scenarios such as wall-mounted, wall-mounted, and floor-mounted. For example, if a PON ONU device is embedded in a wall, a mounting box is embedded in the wall, housing the PON ONU device, while the network interface is located outside the wall for easy connection.

[0004] In the related art, a sheet metal clip is usually provided on the outer wall of the shell of the PON ONU device, and a slot is provided at the corresponding position of the side wall of the installation box. The sheet metal clip is forced into the slot by forcible squeezing. This not only makes installation laborious, but also requires the use of tools to forcibly pry the PON ONU device off the installation box during disassembly, making disassembly difficult and easily causing damage to the device or the clip. Utility Model Content

[0005] The embodiments of the present invention provide an ONU device and an FTTR networking system, which can solve the technical problems existing in related technologies. Specifically, the technical solution is as follows.

[0006] On the one hand, an ONU device is provided, which includes a device body and an elastic clip, and the device body has a receiving groove on the outer walls on both sides arranged opposite to each other, and the receiving groove is used to accommodate the elastic clip; the elastic clip includes a first end, a clip body and a second end distributed in sequence along the axial direction of the receiving groove, the first end is fixedly connected to the inside of the receiving groove, and the clip body and the second end are both separated from the bottom wall of the receiving groove; the clip body is at least partially protruded from the outside of the receiving groove, and the clip body can move toward the direction close to the bottom wall of the receiving groove and be received in the inside of the receiving groove.

[0007] The ONU device provided by the embodiment of the present invention is based on the structural arrangement and elastic characteristics of the elastic clip, so that the clip body can be freely switched between the engaging position and the withdrawing position. During the installation operation, the elastic deformation of the elastic clip itself makes the insertion movement inside the installation box smoother, and after being inserted into place, it automatically returns to the engaging position to ensure a stable connection. During the disassembly operation, the second end can be used as an unlocking component, and the second end can be pressed to achieve the withdrawing of the clip body in the card slot, thereby achieving the smooth disassembly of the ONU device from the installation box. It can be seen that the installation and disassembly operations of the ONU device are not only more convenient and efficient, but also do not require the use of additional tools during disassembly, avoiding additional mechanical stress on the ONU device and effectively avoiding the problem of damage to the device or clip caused by hard contact.

[0008] In some possible implementations, the buckle body includes a wedge-shaped portion and a bent portion, wherein one end of the wedge-shaped portion away from the bent portion is fixedly connected to the first end portion, and one end of the bent portion away from the wedge-shaped portion is fixedly connected to the second end portion; wherein the surface of the wedge-shaped portion facing away from the bottom wall of the accommodating groove is arranged inclined, and the bent portion is arranged to protrude relative to the wedge-shaped portion and the second end toward the bottom wall of the accommodating groove.

[0009] The surface of the wedge-shaped portion facing away from the bottom wall of the groove is designed to be a slope. When the device body is inserted into the installation box, the side wall of the installation box squeezes the slope of the wedge-shaped portion of the buckle body, converting the lateral extrusion force into a component force along the axial direction of the accommodating groove (i.e., pushing the buckle body to shrink toward the bottom wall of the groove). This is not only conducive to guiding the insertion of the device body into the interior of the installation box, but also helps to reduce the insertion resistance and avoid the buckle from getting stuck.

[0010] The bent portion forms the core area of ​​elastic deformation for the elastic buckle. When the elastic buckle is squeezed, the bent portion deforms first relative to the wedge-shaped portion, storing elastic potential energy. This allows it to bend further when pressed, amplifying its displacement and improving the buckle's reset response speed and stability.

[0011] In some possible implementations, a surface of the bent portion facing the bottom wall of the accommodating groove is a plane or an arc surface.

[0012] When the surface of the bent portion facing the bottom wall of the accommodating groove is set to a plane, the plane provides a larger support area when in contact with the bottom wall of the accommodating groove, thereby enhancing the bending stiffness of the bent portion and preventing the buckle from failing due to excessive deformation during pressing.

[0013] When the surface of the bent portion facing the bottom wall of the accommodating groove is set as an arc surface, the arc surface structure causes the bent portion to bend gradually when pressed, thereby avoiding plastic deformation or fracture due to excessive pressing.

[0014] In some possible implementations, the ONU device further includes an elastic reset member, and the elastic reset member is disposed between at least one of the wedge-shaped portion and the bent portion and a bottom wall of the accommodating groove.

[0015] By further providing an elastic reset member, additional elastic control force can be applied to the movement of the buckle body, which is beneficial to enhancing the reset reliability of the elastic buckle and extending its service life, thereby realizing a double insurance mechanism.

[0016] In some possible implementations, the second end of the elastic clip has an anti-slip structure on a surface facing away from the bottom wall of the accommodating groove. This arrangement helps increase the contact friction between the user's finger and the second end, improving the disassembly feel and reliability.

[0017] In some possible implementations, the elastic buckle is an integrally formed spring structure, for example, by injection molding (plastic parts), stamping (sheet metal parts), or 3D printing, which helps enhance the structural strength and operational reliability of the elastic buckle.

[0018] In some possible implementations, the outer wall of the device body on which the elastic clip is disposed includes: a first wall and a second wall, arranged sequentially along the height of the device body, the second wall being closer to the network interface of the device body and convex relative to the first wall. The accommodating slot includes a first slot section defined on the first wall and a second slot section defined on the second wall, the first end portion and the clip body of the elastic clip being accommodated in the first slot section, and the second end portion of the elastic clip being accommodated in the second slot section.

[0019] Through the above arrangement, the second end of the elastic buckle is accommodated in the second groove section on the second wall surface, thereby being exposed to the outside of the installation box, thereby ensuring the reliability of the second end as an unlocking component.

[0020] In some possible implementations, the projections of the elastic clips on the first side outer wall of the device body and the elastic clips on the second side outer wall of the device body onto the first side outer wall or the second side outer wall of the device body are staggered. This arrangement has the advantage that when the installation box is inserted, the elastic clips on both sides contact the side walls of the installation box in staggered contact, which helps disperse stress and improves the service life of the installation box.

[0021] In some possible implementations, the ONU device also includes an installation box, and the device body is partially accommodated in the installation box, wherein a card slot is provided on the side wall of the installation box, the card slot is engaged with the card slot of the card buckle body of the elastic card buckle, and the second end of the elastic card buckle is located outside the installation box.

[0022] On the other hand, an FTTR networking system is provided, which includes a master gateway and a slave gateway, the master gateway and the slave gateway are communicatively connected, and the slave gateway includes any of the above-mentioned ONU devices.

[0023] The FTTR networking system provided by the embodiment of the present invention has all the advantages of the above-mentioned ONU devices, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following will further describe the technical solutions of the embodiments of the present invention in conjunction with the accompanying drawings. When the following description refers to the drawings, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," "outer," "axial," "circumferential," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the drawings. These terms are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Taking the terms "upper" and "lower" as an example, the orientation of the deposition unit can be defined as being below the vapor transport deposition apparatus.

[0038] As a user-side device at the access end, the ONU device can be used to provide users with network interfaces such as telephone, data communication, and image. The ONU device is installed in an installation box, and the installation box is embedded in a wall, the ground, and other scenarios. Taking the installation box embedded in the wall as an example, after the ONU device is installed in the installation box, the ONU device can be partially embedded in the wall and partially exposed outside the wall. The part of the ONU device exposed outside the wall has a network interface to facilitate communication and connection between the ONU device and relevant components in the FTTR networking system.

[0039] The PON ONU device provided by the related art has a sheet metal clip provided on its outer wall, so that when installing, the sheet metal clip on the ONU device is forced into the slot by forcible squeezing, which not only makes installation laborious, but also requires the use of tools to forcibly pry the PON ONU device from the installation box during disassembly, making disassembly difficult and easily causing damage to the device or the clip. The embodiment of the utility model provides a PON ONU device provided with a new clip, which can solve the technical problems existing in the related art.

[0040] As attached Figure 1 As shown, the ONU device includes a device body 100 and an elastic buckle 200. The device body 100 has two oppositely arranged outer walls with accommodating grooves 11, which are used to accommodate the elastic buckle 200. Figure 2 and attached Figure 3 As shown, the elastic clip 200 includes a first end 21, a clip body 22 and a second end 23 distributed in sequence along the axial direction of the accommodating groove 11, the first end 21 is fixedly connected to the inside of the accommodating groove 11, and the clip body 22 and the second end 23 are both separated from the bottom wall 110 of the accommodating groove 11, wherein the clip body 22 is at least partially protruded from the outside of the accommodating groove 11, and the clip body 22 can move toward the direction close to the bottom wall 110 of the accommodating groove 11 and be received in the inside of the accommodating groove 11.

[0041] It should be noted that the device body 100 refers to the other parts of the ONU device except the elastic buckle 200. For example, see Figure 1 The device body 100 includes an outer shell 12, an ONU device module encapsulated within the outer shell 12, and a network interface 13 provided on the outer shell 12. The ONU device module, not shown in the figure, may include a photoelectric conversion device, a circuit board, etc. The network interface 13 is connected to the ONU device module, and the network interface 13 is used to achieve communication between the ONU device and relevant components in the FTTR networking system.

[0042] The ONU device provided by the embodiment of the present invention can be installed in the installation box 400, see Figure 6 The side wall of the installation box 400 corresponding to the elastic buckle 200 is provided with a card slot 41. The following is an exemplary description of the process of installing the ONU device into the installation box 400 and removing it from the installation box 400.

[0043] About the installation of ONU equipment:

[0044] Align the device body 100 of the ONU device with the card slot 41 in the installation box 400, and insert the device body 100 into the installation box 400. Figure 3 The buckle body 22 of the elastic buckle 200 is at least partially protruded from the outside of the accommodating groove 11. As the device body 100 is inserted into the interior of the installation box 400, the buckle body 22 of the elastic buckle 200 is squeezed by the side wall of the installation box 400. Under the squeezing action, the buckle body 22 moves toward the bottom wall 110 of the accommodating groove 11, thereby being received in the interior of the accommodating groove 11 (see Figure 4 ), facilitating smooth insertion of the ONU into the installation box 400. Once the ONU is fully inserted, i.e., the clip body 22 is aligned with the slot 41 on the installation box 400, the clip body 22 is no longer squeezed and elastically releases into the slot 41 (i.e., returns to its natural, outwardly convex position), thereby achieving engagement with the slot 41. Furthermore, the second end 23 of the elastic clip 200 can be positioned not only outside the slot 41 but also outside the installation box 400. In this case, the second end 23 can be considered exposed.

[0045] About disassembly of ONU equipment:

[0046] When you need to dismantle the ONU, refer to Figure 4, press the second end 23 of the elastic clip 200, and the second end 23 of the elastic clip 200 moves toward the bottom wall 110 of the accommodating groove 11. Since the second end 23 of the elastic clip 200 is connected to its clip body 22, it can drive the clip body 22 to move toward the bottom wall 110 of the accommodating groove 11. That is, the clip body 22 moves from the natural state of protruding outside the accommodating groove 11 to the retracted state received inside the accommodating groove 11, so that the clip body 22 can be smoothly removed from the slot 41. While keeping the second end 23 pressed, pull the device body 100 outward to successfully complete the removal of the ONU device from the installation box 400, thereby achieving the disassembly of the ONU device.

[0047] In summary, the ONU device provided by the embodiment of the present invention, based on the structural arrangement and elastic characteristics of the elastic clip 200, enables the clip body 22 to freely switch between the engaging position and the withdrawing position. During the installation operation, the elastic deformation of the elastic clip 200 itself makes its insertion movement inside the installation box 400 smoother, and after being inserted into place, it automatically returns to the engaging position to ensure a stable connection. During the disassembly operation, the second end 23 can be used as an unlocking component. Pressing the second end 23 can realize the withdrawing of the clip body 22 from the card slot 41, thereby realizing the smooth removal of the ONU device from the installation box 400. It can be seen that the installation and disassembly operations of the ONU device are not only more convenient and efficient, but also do not require the use of additional tools during disassembly, avoiding additional mechanical stress on the ONU device and effectively avoiding the problem of damage to the device or clip caused by hard contact.

[0048] The elastic buckle 200 of the embodiment of the present invention can bring about an elastic effect due to its structural characteristics. It can be made of metal or highly elastic and hard engineering plastic material, so that it has both high strength and high elasticity. The material can be selected according to actual needs. For example, the elastic buckle 200 can be made of stainless steel. The first end portion 21 of the elastic buckle 200 is fixedly connected to the interior of the receiving groove 11. For example, the fixing method can be screw connection, rivet connection, bonding, welding, etc.

[0049] The following further describes the structural arrangement of the elastic buckle 200. Figure 2 As shown, the buckle body 22 includes a wedge-shaped portion 221 and a bent portion 222. The end of the wedge-shaped portion 221 away from the bent portion 222 is fixedly connected to the first end portion 21, and the end of the bent portion 222 away from the wedge-shaped portion 221 is fixedly connected to the second end portion 23. The surface of the wedge-shaped portion 221 facing away from the bottom wall 110 of the accommodating groove 11 is arranged at an angle, and the bent portion 222 is arranged to protrude relative to the wedge-shaped portion 221 and the second end portion 23 toward the bottom wall 110 of the accommodating groove 11.

[0050] For the wedge-shaped portion 221, one end thereof is fixedly connected to the first end portion 21, and the other end is connected to the bent portion 222. The end surface of the wedge-shaped portion 221 at one end connected to the bent portion 222 serves as a snap-fit ​​surface to cooperate and lock with the card slot 41. The surface of the wedge-shaped portion 221 facing away from the bottom wall 110 of the slot is designed to be a slope. In this way, when the device body 100 is inserted into the installation box 400, the side wall of the installation box 400 squeezes the slope of the wedge-shaped portion 221 of the buckle body 22 to convert the lateral extrusion force into a component force along the axial direction of the accommodating slot (i.e., pushes the buckle body 22 to shrink toward the bottom wall 110 of the slot), which is not only beneficial for guiding the device body 100 to be inserted into the interior of the installation box 400, but also beneficial for reducing the insertion resistance and avoiding the buckle from getting stuck.

[0051] The bent portion 222 is arranged to project relative to the wedge-shaped portion 221 and the second end portion 23, toward the bottom wall 110 of the receiving groove 11. This arrangement forms the core area where the elastic buckle 200 undergoes elastic deformation. When the elastic buckle 200 is squeezed, the bent portion 222 first undergoes elastic deformation relative to the wedge-shaped portion 221, storing elastic potential energy. This allows it to bend further when pressed, amplifying its displacement and improving the resetting response speed and stability of the elastic buckle 200.

[0052] In addition, the wedge-shaped portion 221 bears the external extrusion force during installation, reducing local stress concentration through the inclined force component, and the bent portion 222 bears the pressing deformation during disassembly. Its arc-shaped structure evenly distributes the strain and avoids material fatigue fracture, which is more beneficial to improving the reliability and durability of the elastic buckle 200.

[0053] For further examples, see Figure 2 The embodiment of the present invention provides such an elastic clip 200, the first end portion 21 of the elastic clip 200 is flat, so that it is laid flat on the bottom wall 110 of the accommodating groove 11, and is firmly installed inside. The wedge-shaped portion 221 of the clip body 22 includes an inclined plate segment and a flat plate segment arranged at an angle. Although the connection between the inclined plate segment and the flat plate segment forms an angle (for example, 90°), the connection is expected to have a smooth transition to ensure that the clip body 22 still maintains good structural stability under frequent deformation conditions.

[0054] From the end where the inclined plate section of the wedge-shaped portion 221 connects to the first end portion 21 to the end where the inclined plate section of the wedge-shaped portion 221 connects to the flat plate section, the distance between the inclined plate section of the wedge-shaped portion 221 and the bottom wall 110 of the receiving groove 11 gradually increases, ensuring that the flat plate section of the wedge-shaped portion 221 at least partially protrudes outside the receiving groove 11. During use, the flat plate section of the wedge-shaped portion 221 abuts against the wall of the locking groove 41 to achieve a stable locking connection.

[0055] In the embodiment of the present invention, the surface of the bent portion 222 facing the bottom wall 110 of the accommodating groove 11 can be a plane (see Figure 2 ), it can also be a curved surface (not shown in the figure), and it is not ruled out that the surface of the groove bottom wall 110 of the bending portion 222 facing the accommodating groove 11 is set to other structural forms, for example, it is set to an uneven shape.

[0056] When the surface of the bent portion 222 facing the bottom wall 110 of the receiving groove 11 is configured as a flat surface, the flat surface provides a larger support area when in contact with the bottom wall 110 of the receiving groove 11, thereby enhancing the bending rigidity of the bent portion 222 and preventing excessive deformation during pressing that could cause the buckle to fail. In this case, the bent portion 222 can, for example, be an L-shaped plate structure.

[0057] When the surface of the bent portion 222 facing the bottom wall 110 of the receiving groove 11 is configured as an arc, the arcuate structure causes the bent portion 222 to bend gradually when pressed, preventing plastic deformation or fracture caused by excessive pressure. In this case, the bent portion 222 can, for example, be an arc-shaped plate. It is not excluded that the bent portion 222 can be configured to have multiple bending locations, which is conducive to providing a larger elastic travel.

[0058] In some implementations, such as the attached Figure 5 As shown, the ONU device may further include an elastic reset member 300 , which is disposed between at least one of the wedge-shaped portion 221 and the bent portion 222 and the bottom wall 110 of the accommodating groove 11 .

[0059] For example, the elastic return member 300 is disposed between the wedge-shaped portion 221 and the bottom wall 110 of the receiving groove 11. The elastic return member 300 may be, for example, in the form of an elastic arm. Alternatively, the elastic return member 300 is disposed between the bent portion 222 and the bottom wall 110 of the receiving groove 11. The elastic return member 300 may be, for example, in the form of a spring. Alternatively, the elastic return member 300 is disposed between both the wedge-shaped portion 221 and the bent portion 222 and the bottom wall 110 of the receiving groove 11. The elastic return member 300 may be, for example, in the form of an elastic gasket.

[0060] By further providing an elastic return member 300, which can be, for example, a spring, an elastic silicone pad, etc., an additional elastic control force can be applied to the movement of the buckle body 22, thereby enhancing the return reliability of the elastic buckle 200 and extending its service life, thereby achieving a double insurance mechanism. In addition, the elastic return member 300 can be configured to provide the elastic buckle 200 with a force in a direction away from the bottom wall 110 of the accommodating groove 11 when the elastic buckle 200 is in a natural state, which is more conducive to promoting a secure clamping effect.

[0061] Based on any of the aforementioned elastic clips 200, in some examples, the surface of the second end portion 23 of the elastic clip 200, which faces away from the bottom wall 110 of the receiving groove 11, has an anti-slip structure. For example, the anti-slip structure can be an anti-slip coating, or it can be anti-slip lines or bumps provided on the surface of the second end portion 23 of the elastic clip 200, which faces away from the bottom wall 110 of the receiving groove 11. This arrangement helps increase the contact friction between the user's finger and the second end portion 23, improving the disassembly feel and reliability.

[0062] For any of the ONU devices mentioned above, its elastic clip 200 can be an integrally molded spring structure or a split structure (i.e., the first end 21, the clip body 22, and the second end 23 are fixedly connected respectively). In some examples, the elastic clip 200 can be an integrally molded spring structure, for example, it can be prepared by one-step molding by injection molding (plastic parts), stamping (sheet metal parts) or 3D printing, which is conducive to enhancing the structural strength and operational reliability of the elastic clip 200.

[0063] For any of the ONU devices mentioned above, elastic clips 200 are provided on any two relatively arranged outer walls of the outer shell 12 of the device body 100. The number of elastic clips 200 provided on each outer wall can be one or more (for example, two symmetrically arranged).

[0064] In some examples, such as the attached Figure 6 As shown, the outer wall of the device body 100, on which the elastic clip 200 is provided, includes: a first wall surface 121 and a second wall surface 122, which are sequentially distributed along the height direction of the device body 100. The second wall surface 122 is closer to the network interface 13 of the device body 100 and is arranged to protrude outward relative to the first wall surface 121. The accommodating groove 11 includes a first groove section 111 formed on the first wall surface 121 and a second groove section 112 formed on the second wall surface 122. The first end portion 21 and the clip body 22 of the elastic clip 200 are accommodated in the first groove section 111, and the second end portion 23 of the elastic clip 200 is accommodated in the second groove section 112.

[0065] With the above arrangement, when the ONU device is inserted into the installation box 400, the first wall 121 of the device body 100 is accommodated within the installation box 400. Since the second wall 122 of the device body 100 is arranged to protrude outward from the first wall 121, the junction between the first wall 121 and the second wall 122 forms a stop with the port of the installation box 400, thereby exposing the second wall 122 of the device body 100 to the outside of the installation box 400. Accordingly, the first end 21 and the main body 22 of the elastic clip 200 are accommodated in the first slot section 111 of the first wall 121, thereby being accommodated within the installation box 400, while the second end 23 of the elastic clip 200 is accommodated in the second slot section 112 of the second wall 122, thereby being exposed to the outside of the installation box 400, thereby ensuring the reliability of the second end 23 as an unlocking component.

[0066] In the embodiment of the present invention, the elastic buckles 200 located on the first side outer wall of the device body 100 and the elastic buckles 200 located on the second side outer wall of the device body 100 can be arranged in a one-to-one correspondence relative to each other or in a staggered arrangement.

[0067] For example, the projections on the first side outer wall or the second side outer wall of the device body 100 are arranged in a staggered manner. The advantage of such an arrangement is that when the installation box 400 is inserted, the elastic buckles 200 on both sides stagger their contact with the side walls of the installation box 400, which is conducive to stress dispersion and improves the service life of the installation box 400.

[0068] In combination with any of the above-mentioned ONU devices, such as the attached Figure 6 As shown, the ONU device also includes an installation box 400, and the device body 100 is partially accommodated in the installation box 400, wherein a card slot 41 is provided on the side wall of the installation box 400, the card slot 41 is engaged with the card slot 41, and the second end 23 of the elastic card slot 200 is located outside the installation box 400.

[0069] The installation box 400 can be embedded in a wall or in the ground (such as a floor bucket), so that the ONU device can be suitable for different application scenarios.

[0070] Furthermore, the side wall of the installation box 400 also has a guide groove 42, the depth of the guide groove 42 is less than the depth of the card slot 41, and the guide groove 42 extends from the port of the installation box 400 to the card slot 41, which is used to guide the insertion movement of the elastic clip 200 to ensure that it is inserted into place quickly and accurately.

[0071] On the other hand, an embodiment of the present invention further provides an FTTR networking system, which includes a master gateway and a slave gateway, the master gateway and the slave gateway are communicatively connected, and the slave gateway includes any of the above-mentioned ONU devices.

[0072] The FTTR networking system provided by the embodiment of the present invention has all the advantages of the above-mentioned ONU devices, which will not be described in detail here.

[0073] In some examples, in an FTTR networking system, the master gateway is an optical network terminal (ONT), which is connected to an optical line terminal (OLT) to form a slave gateway. The ONT can provide a downstream optical interface and connect to the ONU device to form a slave gateway.

[0074] The above description is only for the purpose of facilitating those skilled in the art to understand the technical solutions of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the scope of protection of the present disclosure.
