ODN connects an OLT device and multiple ONU devices to provide bidirectional transmission of optical signals. In order to meet the needs of optical fiber deployment and management, ODN projects need to use connection boxes (such as optical handover boxes, optical distribution boxes, optical fiber splitter boxes, etc.), which integrate different numbers and types of passive optical devices inside these connection boxes.

[0003] As competition in the ODN industry becomes increasingly fierce, the cost of connection box products has become one of the important issues, and the market demand for low cost and high reliability of connection box products is unprecedentedly strong.

[0004] In the related art, the connection box is generally provided with an adapter to achieve the docking of the optical fibers in the two connectors. When manufacturing the connection box, the adapter and the connection box are generally produced separately, and then the adapter is assembled to the connection box. However, this method not only requires the assembly of the internal parts of the adapter, but also requires the overall assembly of the adapter to the connection box, which makes the assembly cost high, and improper installation of the adapter may cause the adapter to fall off, affecting the reliability of the product.

[0005] Therefore, it is necessary to design a new connection box to overcome the above problems. Summary of the invention

[0039] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] The embodiment of the present application provides a connection box, which can solve the technical problems in the related art of producing and reassembling an adapter and a connection box separately, which has high assembly cost and easily causes the adapter to fall off.

[0041] See also Figure 1 and Figure 2 As shown, a connection box provided in an embodiment of the present application may include: a box body 1, wherein the box body 1 is integrally formed with an adapter body 2; a connector joint 3, wherein the connector joint 3 is arranged in the adapter body 2, and a ceramic sleeve 4 and a ferrule 5 assembled at one end of the ceramic sleeve 4 are arranged in the connector joint 3. Among them, "integrally formed" means that an integral structure is formed by injection molding or stamping, and no additional connection method is required to connect two or more parts. This embodiment is explained by taking the injection molding of the box body 1 and the adapter body 2 as an example, and the ferrule 5 is preferably a ceramic ferrule 5.

[0042] In this embodiment, the adapter body 2 is internally connected to the connector connector 3 (see Figure 8As shown), a connector can be connected to the outside, and the connector joint 3 can be integrally formed with the adapter body 2, or it can be separately formed from the adapter body 2 and then assembled into the adapter body 2. In order to facilitate the assembly of the ceramic sleeve 4 and the ferrule 5, the present embodiment preferably molds the connector joint 3 separately from the adapter body 2, that is, in the process of integrally molding the adapter body 2 and the box body 1, the connector joint 3 is not molded in the adapter body 2 together.

[0043] In this embodiment, the adapter body 2 is integrally formed on the box body 1. After the box body 1 is formed, there is no need to assemble the adapter body 2 to the box body 1 one by one, which can reduce the steps of assembling the adapter body 2 and the box body 1, reduce the assembly cost, and reduce the number of assembly times. In addition, the adapter body 2 integrally formed on the box body 1 is not easy to fall off the box body 1, thereby improving the reliability of the product. The connector joint 3, ceramic sleeve 4 and ferrule 5 arranged in the adapter body 2 can realize the docking of the adapter and the connector, which solves the technical problem of high assembly cost and easy to cause the adapter to fall off in the related art of producing and reassembling the adapter and the connection box separately.

[0044] Further, see Figure 3 and Figure 4 As shown, in one embodiment, the box body 1 includes a box body 11 and a panel 12 installed at the opening of the box body 11, and the adapter body 2 is integrally formed on the panel 12. In this embodiment, in order to facilitate the installation of the internal components of the box body 1, the box body 1 is split into the box body 11 and the panel 12. The box body 11 has an opening, and the panel 12 is installed at the opening of the box body 11, which can block the opening of the box body 11 and achieve the sealing of the inside of the box body 11. At the same time, the adapter body 2 integrally formed on the panel 12 facilitates the docking of the optical fibers inside and outside the box body 1. See Figure 7 shown.

[0045] Of course, in other embodiments, the adapter body 2 may be integrally formed on the box body 11 , or part of the adapter body 2 may be integrally formed on the box body 11 , and part of the adapter body 2 may be integrally formed on the panel 12 .

[0046] In some optional embodiments, the box body 11 may also be integrally formed with the panel 12, that is, the entire box body 1 may be integrally formed.

[0047] Further, see Figure 4As shown, preferably, the box body 11 and the panel 12 are fixed by laser welding, so that the panel 12 seals the opening of the box body 11. In this embodiment, a circle of the panel 12 is welded and fixed to the box body 11 by laser welding, which not only achieves the fixation of the box body 11 and the panel 12, but also ensures airtightness, and the fixing and sealing is fast and reliable.

[0048] In other embodiments, the box body 11 and the panel 12 may also be fixed in other ways, such as adhesive bonding or bolt connection.

[0049] Further, see Figure 4 and Figure 6 As shown, in some embodiments, a protrusion 111 is provided at one end of the box body 11 close to the panel 12, and a groove 112 is provided on the periphery of the protrusion 111, and the protrusion 111 is laser welded to the panel 12. In this embodiment, a circle of protrusions 111 can be provided on the end surface of the box body 11, that is, a ring-shaped protrusion 111 is formed, and the ring-shaped protrusion 111 surrounds the opening of the box body 11. When the protrusion 111 is laser welded to the panel 12, the opening can be sealed around the periphery of the opening to ensure air tightness; at the same time, the groove 112 provided on the periphery of the protrusion 111 is also provided on the outside of the protrusion 111. The groove 112 can accommodate the protrusion 111 melted after laser welding, so that the molten plastic will not flow to the outside of the box body 1.

[0050] See also Fig. 9 and Fig.10 As shown, in some optional embodiments, one end of the connector joint 3 is provided with a C-shaped buckle 31, and the C-shaped buckle 31 is clamped with the end of the ceramic sleeve 4 away from the ferrule 5. Fig.12 As shown, in this embodiment, the C-type buckle 31 can be integrally formed with the connector joint 3, or it can be separately formed and then fixed on the connector joint 3. The C-type buckle 31 is buckled at one end of the ceramic sleeve 4, and the center angle of the C-type buckle 31 is preferably 180°, that is, the C-type buckle 31 fixes the ceramic sleeve 4 in the form of a half buckle; of course, the center angle of the C-type buckle 31 can also be other angles, which are not limited here. The C-type buckle 31 can restrict the ceramic sleeve 4 at one end of the ceramic sleeve 4, prevent the ceramic sleeve 4 from falling off from the connector joint 3, and limit the ceramic sleeve 4 to a suitable position; using the C-type buckle 31 instead of a complete annular buckle can not only reduce costs, but also facilitate the assembly of the ceramic sleeve 4.

[0051] Further, see Fig.13As shown, in one embodiment, the connector joint 3 includes a joint body 32, a receiving cavity 321 is provided in the joint body 32, a mounting opening 322 which is in communication with the receiving cavity 321 is opened in the radial direction of the joint body 32, the ceramic sleeve 4 and the ferrule 5 are installed in the receiving cavity 321 from the mounting opening 322, and the C-shaped buckle 31 is provided at one end of the joint body 32. In this embodiment, a mounting opening 322 which is axially extending and longitudinally extending along the joint body 32 is opened in the radial direction of the joint body 32, so that the ceramic sleeve 4 and the ferrule 5 can be installed in the receiving cavity 321 from the radial direction of the joint body 32, rather than being inserted into the receiving cavity 321 from one end of the joint body 32 in the axial direction. The ceramic sleeve 4 and the ferrule 5 are installed by using the mounting opening 322 provided in this embodiment, which can shorten the moving path of the ceramic sleeve 4 and the ferrule 5 during the installation process, improve the installation efficiency, and at the same time, can save the material used for the joint body 32, thereby reducing the cost.

[0052] See also Fig.10 and Fig.11 As shown, preferably, the C-shaped buckle 31 is integrally formed with the connector body 32. In this embodiment, the C-shaped buckle 31 and the connector body 32 can be integrally injection molded. During the injection molding process of the C-shaped buckle 31 and the connector body 32, the C-shaped buckle 31 is also used to facilitate the demolding of the molded connector connector 3.

[0053] Further, see Fig.10 As shown, in one embodiment, the C-type buckle 31 and the joint body 32 are respectively located on opposite sides of the ceramic sleeve 4. In this embodiment, the joint body 32 is located on the left side of the ceramic sleeve 4, and the C-type buckle 31 is located on the right side of the ceramic sleeve 4. The C-type buckle 31 is bent and extended from the connection with the joint body 32 toward the side away from the joint body 32, so that a gap 34 is formed between the left side of the C-type buckle 31 and the joint body 32; and the axes of the C-type buckle 31 and the joint body 32 are colinear, and the C-type buckle 31 and the joint body 32 can radially position the ceramic sleeve 4 on the left and right sides of the ceramic sleeve 4, so that the ceramic sleeve 4 cannot be radially separated from the C-type buckle 31 and the joint body 32. At the same time, the C-type buckle 31 is buckled at the front end of the ceramic sleeve 4, and can axially limit the ceramic sleeve 4.

[0054] Preferably, see Fig.11As shown, two elastic arms 323 can be provided in the middle of the connector body 32, and the two elastic arms 323 can axially limit the other end of the ceramic sleeve 4, so that the C-shaped buckle 31 and the elastic arms 323 respectively limit the ceramic sleeve 4 axially at both ends of the ceramic sleeve 4. In this embodiment, one end of the ferrule 5 is sleeved in the ceramic sleeve 4, and a spring 7 can be sleeved outside the ferrule 5. The ferrule 5 and the ceramic sleeve 4 are inserted into the receiving cavity 321 of the connector body 32 through the installation port 322. At the same time, during the insertion of the ferrule 5 and the ceramic sleeve 4, the inclined surface on the elastic arm 323 can guide the ferrule 5. After the ferrule 5 and the ceramic sleeve 4 are inserted into the receiving cavity 321, the two elastic arms 323 approach each other, which can limit the ferrule 5 from radially escaping from the receiving cavity 321. In addition, a limiting structure for axially limiting the ferrule 5 is also provided on the connector body 32.

[0055] Based on the above technical solution, see Fig.13 As shown, in some embodiments, an operating handle 33 is provided at one end of the connector body 32 away from the C-shaped buckle 31, and a buckle structure 331 is provided on the operating handle 33. The connector body 32 is buckled and fixed to the adapter body 2 through the buckle structure 331. In this embodiment, the buckle structure 331 on the operating handle 33 is preferably a convex bump, and correspondingly, a buckle groove can be provided on the adapter body 2. When the operating handle 33 is pinched, the convex bump can easily enter the buckle groove and be buckled and fixed in the buckle groove. When it is necessary to remove the connector connector 3, the operating handle 33 can be pinched again to make the convex bump fall out of the buckle groove ( Fig. 9 In other embodiments, the buckle groove may be provided on the operating handle 33, and on the contrary, the convex bump may be provided on the adapter body 2.

[0056] Further, see Figure 5 As shown, in some optional embodiments, the connection box may further include a dust plug 6, which is inserted into the adapter body 2 and located outside the box body 1. In this embodiment, when the adapter body 2 is not in use, the dust plug 6 can be inserted into one end of the adapter body 2 located outside the box body 1, so that the dust plug 6 can block the outer end of the adapter body 2, which can play a role in dust and water prevention. When the adapter body 2 needs to be used, the dust plug 6 can be removed. At the same time, the dust plug 6 can be fixed with the adapter body 2 by buckles, which is convenient for disassembly and reversing.

[0057] In order to ensure the high reliability and low cost requirements of the connection box, the present application provides a connection box, whose adapter body 2 and panel 12 are integrally formed and fixed to the box body 11 using laser welding technology, thereby reducing assembly costs, reducing assembly times, saving labor, and improving product reliability.
