Description

Technical Field

[0001] This application relates to the field of communication connection technology, and in particular to a connection box. Background Technology

[0002] An Optical Distribution Network (ODN) is a network consisting of all passive optical fibers and passive devices (such as optical splitters) between Optical Line Terminals (OLTs) and Optical Network Units (ONUs). An ODN connects one OLT device to multiple ONU devices, providing bidirectional transmission of optical signals. ODN projects utilize junction boxes (such as optical cross-connect boxes, optical distribution boxes, and optical fiber splitter boxes), which integrate different numbers and types of passive optical devices to meet the needs of optical fiber deployment and management.

[0003] With increasingly fierce competition in the ODN industry, the cost of connector boxes has become a critical issue, and the market demand for low-cost, high-reliability connector boxes is unprecedentedly strong. In related technologies, a connector box includes a housing and an adapter mounted on the housing. One end of the adapter is located inside the housing, and the other end is located outside. Its two ends connect to connectors located inside and outside the housing, respectively, to achieve the connection of two optical fibers. Generally, the housing of the connector box is larger and has lower requirements for dimensional accuracy, while the adapter has high requirements for dimensional accuracy and is typically manufactured using high-polymer materials with good dimensional stability and weather resistance. The adapter and housing are manufactured separately, and then the adapter is assembled onto the housing using nuts and fasteners.

[0004] However, in the above connection method, the adapter needs to be tightened onto the housing with nuts and fasteners at a certain torque. The assembly process is relatively long and the installation process is cumbersome and complicated, which increases the assembly cost of the connection box. Summary of the Invention

[0005] This application provides a connector box to solve the problem that in existing connector boxes, the adapter is locked to the housing by nuts and fasteners, which is cumbersome, time-consuming, and increases the assembly cost of the connector box.

[0006] This application provides a connecting box, including a housing, an adapter panel disposed at one end of the housing, and a first connecting module disposed on the adapter panel;

[0007] The adapter panel has mounting holes, and the first connecting module is detachably installed in the mounting holes by snap-fitting.

[0008] The first connection module is used to connect to the first connector.

[0009] The first connecting module is detachably mounted on the adapter panel via a snap-fit ​​connection, facilitating the installation and removal of both. This eliminates the need for tightening nuts and fasteners, making installation simple and reliable. It effectively simplifies the assembly process between the connecting module and the housing, shortens assembly time, and thus reduces the assembly cost of the connecting box. Furthermore, the snap-fit ​​connection reduces or eliminates loosening between the connecting module and the adapter panel, improving the reliability and stability of their connection. This prevents loosening from affecting the seal between the two, thus enhancing the sealing performance of the connecting box.

[0010] In one possible implementation, a first connecting portion is provided on the outside of the adapter panel, the first connecting portion surrounds the outer periphery of the mounting hole, and the first connecting portion and the adapter panel are an integral structure.

[0011] The first connector includes a first inner connector located inside the housing and a first outer connector located outside the housing;

[0012] The first connecting part is used to connect with the first external connector. By making the first connecting part and the adapter panel an integrated structure, the reliability and stability of the seal between the connecting module and the adapter panel can be effectively improved, reducing or avoiding problems such as seal failure between the connecting module and the adapter panel, thereby effectively improving the sealing performance of the connecting box and enhancing the stability and reliability of the connecting box operation.

[0013] In one possible implementation, the first connection module includes a first inner module and a first outer module that are internally connected.

[0014] The first inner module is used to connect with the first inner connector, and the first outer module is used to connect with the first outer connector.

[0015] In one possible implementation, a second connecting portion is further provided on the inner side of the adapter panel; the second connecting portion surrounds the outer periphery of the mounting hole, and the second connecting portion and the adapter panel are an integral structure; the second connecting portion is used to connect with the first inner module. This can effectively improve the robustness and stability of the connection between the second connecting portion and the adapter panel, and help improve the reliability and stability of the connection between the first connecting module and the adapter panel.

[0016] In one possible implementation, the second connecting part is provided with a positioning groove; the first inner module is provided with a positioning block that engages with the positioning groove; the positioning block is engaged within the positioning groove. This allows workers to easily locate the installation position during assembly, preventing the connection module from being misaligned and affecting the normal installation of the connection module and the adapter panel, effectively preventing errors, reducing the error rate, and thus effectively improving the assembly efficiency of the connection box.

[0017] In one possible implementation, the second connecting portion is further provided with a locking hole; the first inner module is provided with a first locking portion that mates with the locking hole; the first locking portion is engaged within the locking hole. The locking hole can limit the first locking portion in the axial and circumferential directions of the second connecting portion, thereby preventing the first connecting module from shifting in the axial and circumferential directions of the second connecting portion, preventing the connecting module from separating from the adapter panel, and effectively improving the reliability and firmness of the connection between the connecting module and the adapter panel.

[0018] In one possible implementation, the first latching portion is a cantilever structure to make it flexible. This facilitates the removal of the connecting module from the second connecting portion.

[0019] In one possible implementation, the inner wall of the second connecting portion further has a first cut surface, on which the locking hole is located; the outer side of the first inner module has a second cut surface, which fits against the first cut surface. The fit between the first and second cut surfaces provides a circumferential limit for the first connecting module in the second connecting portion, preventing rotation and improving the reliability and stability of the connection between the first connecting module and the adapter panel. Furthermore, the first cut surface can increase the wall thickness of the second connecting portion, reducing or preventing cracking of the locking hole and improving its structural stability, thereby enhancing the reliability and stability of the connection between the connecting module and the adapter panel.

[0020] In one possible implementation, the inner diameter of the second connecting portion is larger than the diameter of the mounting hole, forming a limiting platform inside the second connecting portion; the first inner module is provided with a limiting portion that mates with the limiting platform; the limiting portion abuts against the limiting platform. Through the cooperation between the limiting platform and the limiting portion, the first connecting module can be limited axially in the second connecting portion, preventing the first connecting module from being improperly installed axially in the second connecting portion. This improves the accuracy of the connecting module installation and effectively enhances the assembly precision of the connecting box.

[0021] In one possible implementation, the first inner module has a second latching portion for engaging with a slot on the first inner connector. This effectively prevents the first inner connector from disengaging from the first inner module, thereby improving the reliability and stability of the connection between them and enhancing the stability of optical signal transmission between the first inner connector and the first outer connector.

[0022] In one possible implementation, the first outer module is provided with a guide block, which is used to mate with a guide groove on the first outer connector. This can prevent the first outer connector from deflecting or misaligning during the connection process with the first outer module, thereby improving the reliability and stability of the mating between the first outer connector and the first outer module.

[0023] In one possible implementation, a rotating groove is formed on the outer periphery of the first connecting portion, which engages with a limiting protrusion on the first external connector. The rotating groove limits the axial movement of the limiting protrusion on the first connecting portion, preventing the first external connector, located outside the housing, from shifting or deflecting axially. This helps improve the reliability and stability of the connection between the first external connector and the first connecting portion, and enhances the stability and reliability of optical signal transmission between the two connectors inside and outside the housing.

[0024] In one possible implementation, the rotating slot includes a first slot and a second slot that are connected to each other; the first slot extends from the outer end face of the first connecting portion to the second slot, and the second slot extends along the outer periphery of the first connecting portion. The second slot can limit the positioning protrusion, preventing it from moving axially along the first connecting portion, thereby avoiding axial displacement of the first external connector along the first connecting portion, and effectively improving the firmness and reliability of the fit between the first external connector and the first connecting portion.

[0025] In one possible implementation, the first connecting module is provided with a limiting plate and a retractable spring block; the limiting plate abuts against one side of the adapter panel, and the spring block abuts against the other side of the adapter panel. The connection between the connecting module and the adapter panel can be achieved through the cooperation of the spring block and the limiting plate. Its structure is simple and easy to operate, effectively improving the convenience of assembling the first connecting module and the adapter panel, thereby effectively improving the assembly efficiency of the connecting box.

[0026] In one possible implementation, a second connection module and a third connection module are further included; the second and third connection modules are detachably mounted within the mounting hole via a snap-fit ​​mechanism; the second connection module is used to connect to a second connector, and the third connection module is used to connect to a third connector, wherein the second connector, the third connector, and the first connector are different types of fiber optic connectors. This allows the connection box to connect to three different types of fiber optic connectors simultaneously, enabling the connection box to meet the connection requirements of more connector types, effectively improving the flexibility of the connection box and fiber optic connectors, and enhancing the versatility of the connection box.

[0027] In one possible implementation, the second connector includes a second inner connector located within the housing and a second outer connector located outside the housing;

[0028] The third connector includes a third inner connector located inside the housing and a third outer connector located outside the housing;

[0029] The second external connector and the third external connector are respectively connected to the first connecting part.

[0030] In one possible implementation, the second connection module includes a second inner module and a second outer module that are internally connected, and the third connection module includes a third inner module and a third outer module that are internally connected.

[0031] The second inner module is used to connect with the second inner connector, and the second outer module is used to connect with the second outer connector;

[0032] The third inner module is used to connect with the third inner connector, and the third outer module is used to connect with the third outer connector;

[0033] The second inner module and the third inner module are also connected to the second connecting part, respectively.

[0034] In one possible implementation, the second inner module includes a first connecting cavity and a second connecting cavity, which are respectively used to mate with two connectors on the second inner connector. This can reduce or avoid movement or misalignment of the second inner connector, effectively improving the reliability and stability of the connection between the second inner connector and the second inner module.

[0035] In one possible implementation, the third inner module has a third latching portion for engaging with a slot on the third inner connector. This can reduce or prevent misalignment or displacement of the third inner connector, contributing to improved reliability and stability of the fit between the third inner connector and the third inner module.

[0036] In one possible implementation, a groove is formed on the inner wall of one side of the third outer module, which is used to cooperate with a slider on the outer side of the third outer connector. This facilitates accurate positioning during assembly, prevents errors, and improves the assembly efficiency between the third outer connector and the third outer module.

[0037] In one possible implementation, an identification panel is also included, located outside the adapter panel, and the identification panel is detachably connected to the adapter panel or the housing.

[0038] A clearance opening is provided on the label panel opposite the mounting hole, through which the first outer module, the second outer module, and the third outer module communicate with the outside of the housing. This facilitates the special customization of the connector box, increases the flexibility of connector box customization, and reduces customization costs.

[0039] In one possible implementation, the first connection module is an SC fiber optic adapter, the second connection module is a DLC fiber optic adapter, and the third connection module is an MPO fiber optic adapter. Attached Figure Description

[0076] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.

[0077] OLT and ONU refer to the connection devices in an optical transmission network, and are two essential modules in a Passive Optical Network (PON). ODN is a Fiber to the Home (FTTH) optical cable network based on PON equipment. The role of ODN is to provide an optical transmission channel between OLT and ONU.

[0078] ODN projects utilize numerous box-type devices such as optical distribution boxes, optical distribution frames, and optical fiber splitters, integrating varying numbers and types of passive optical components to meet the needs of fiber optic deployment and management. These box-type devices typically include adapters, which connect two fiber optic segments by positioning two connectors within sleeves in the adapter.

[0079] Figure 1 This is a schematic diagram of the connection box in the related technology.

[0080] refer to Figure 1 As shown, in the related technology, the connection box 1 includes a housing 11 and an adapter 12 mounted on the housing 11. One end of the adapter 12 is located inside the housing 11 for connecting to a connector inside the housing 11, and the other end is located outside the housing 11 for connecting to a connector (e.g., a fiber optic connector) outside the housing 11. The connector inside the housing 11 and the connector outside the housing 11 are connected via the adapter 12 to connect two fiber optic cables.

[0081] The adapter 12 is provided with a nut fastener 13. One end of the adapter 12 passes through a through hole in the housing 11 and is located inside the housing 11. The nut fastener 13 is screwed onto the end of the adapter 12 located inside the housing 11, so that the adapter 12 is connected to the housing 11 through the nut fastener 13. In addition, a first sealing ring 14 and a second sealing ring 15 are provided between the adapter 12 and the housing 11. The first sealing ring 14 and the second sealing ring 15 are located inside and outside the housing 11, respectively, to achieve a seal at the joint between the adapter 12 and the housing 11.

[0082] However, the adapter needs to be tightened onto the housing with nuts and fasteners to a certain torque. Its assembly process is relatively demanding, takes a long time, and is quite complicated, which increases the assembly cost of the connector box.

[0083] Furthermore, threaded connections are prone to loosening during prolonged use, which can cause the sealing ring between the adapter and the housing to loosen, reducing the sealing performance between the adapter and the housing.

[0084] In another related technology, a connector box is also provided, in which the housing and the adapter are integrally formed, so that the adapter and the housing are an integrated structure, thereby solving the problems of high assembly cost and sealing failure between the adapter and the housing.

[0085] However, since the adapter and housing are molded as a single unit, they can only connect to fiber optic connectors of a specific specification, making it difficult to meet the connection requirements of different connector models. When the adapter needs to be used with different connector models, a new molding die must be designed, greatly reducing the flexibility of the connector box.

[0086] Moreover, the adapter has a relatively complex structure, with one end located inside the housing and the other end outside. The mold structure for integrating the adapter and the housing is quite complex and difficult to design, which increases the difficulty of manufacturing the connector box.

[0087] To address the aforementioned issues, researchers devised an improvement to the connector box's structure. This involved creating mounting holes on the adapter panel and attaching a first connecting module via a snap-fit ​​mechanism. This first connecting module connects to the first connector. This design facilitates the installation and removal of the adapter from the housing, effectively reducing assembly costs and improving assembly efficiency.

[0088] Figure 2 This is a schematic diagram of the structure of a connecting box provided in an embodiment of this application. Figure 3 This is an exploded view of the connector box provided in an embodiment of this application.

[0089] See 2 and Figure 3 As shown, this application embodiment provides a connection box 100, which may include a housing 110, an adapter panel 120 disposed at one end of the housing 110, and a first connection module 130 disposed on the adapter panel 120.

[0090] For example, a mounting hole 121 may be provided on the adapter panel 120, and the first connecting module 130 may be detachably disposed in the mounting hole 121 by snap-fit. For example, an assembly groove that mates with the mounting hole 121 may be provided on the first connecting module 130, and the edge of the mounting hole 121 may be snapped into the assembly groove, so that the first connecting module 130 can be connected to the adapter panel 120 through the engagement of the assembly groove and the mounting hole 121.

[0091] The first connection module 130 can be used to connect with the first connector 2 (see reference). Figure 6 As shown, the first connector 2 can be an SC connector (Square Connector). Correspondingly, the first connection module 130 can be an SC adapter.

[0092] Alternatively, in some examples, the first connector 2 can also be a DLC connector (Double Lucent Connector), and correspondingly, the first connection module 130 can be a DLC adapter.

[0093] Alternatively, in other examples, the first connector 2 may also be an MPO connector (Multi-fiber Pull Off), and correspondingly, the first connection module 130 may be an MPO adapter.

[0094] For example, the housing 110 and the adapter panel 120 can together form a receiving cavity 111 (see reference). Figure 6 As shown, one end of the first connecting module 130 can be located inside the receiving cavity 111, and the other end can be located outside the receiving cavity 111. The end of the first connecting module 130 located in the receiving cavity 111 can be connected to the first connector 2 located inside the receiving cavity 111. The other end located outside the housing 110 can be connected to the first connector 2 outside the housing 110. This allows the two first connectors 2 located inside and outside the housing 110 to be connected through the first connecting module 130, enabling the transmission of optical signals between the two first connectors 2 through the first connecting module 130.

[0095] During use, different models of first connection modules can be installed on the adapter panel 120 according to specific connection requirements, so that the first connection module 130 can be connected to different models of connectors, allowing the connection box to meet the connection requirements of different connector models. For example, when the connection box 100 needs to be connected to an SC connector, the SC adapter model first connection module 130 can be inserted into the mounting hole 121, allowing the SC connector located outside the housing 110 to connect with the SC connector located inside the housing 110 through the first connection module 130. Alternatively, when the position where the SC adapter model first connection module 130 is installed needs to be connected to other models of connectors (e.g., DLC connectors or MPO connectors), the first connection module 130 can be removed from the mounting hole 121, and then the corresponding model (e.g., DLC adapter or MPO adapter) first connection module 130 can be inserted into the mounting hole 121, allowing the connector located outside the housing 110 to connect with the connector inside the housing 110 through the first connection module 130.

[0096] Compared to the method of locking the adapter to the housing with nuts and fasteners in related technologies, the embodiments of this application use a snap-fit ​​method to detachably mount the first connecting module 130 on the adapter panel 120. This facilitates the installation and removal of the first connecting module 130 and the adapter panel 120, eliminating the need for tightening nuts and fasteners. The installation process is simple and reliable, effectively simplifying the assembly work between the first connecting module 130 and the housing 110, shortening the assembly time, and thus effectively reducing the assembly cost of the connecting box 100. Moreover, the snap-fit ​​connection can reduce or avoid loosening between the first connecting module 130 and the adapter panel 120, which helps to improve the reliability and stability of the connection between the first connecting module 130 and the adapter panel 120, prevents the sealing performance between the two from being affected by loosening, and helps to improve the sealing performance of the connecting box 100.

[0097] Compared to another related technology that integrates the adapter and housing, this embodiment of the application separately molds the first connecting module 130 and the adapter panel 120, and then snaps the first connecting module 130 onto the adapter panel 120, allowing for a detachable connection between the first connecting module 130 and the adapter panel 120. This way, when the connection box 100 needs to connect with different types of connectors, only the different types of first connecting modules 130 need to be replaced to connect with the corresponding connectors, enabling the connection box 100 to meet the connection requirements of different connector types, thereby effectively improving the flexibility and versatility of the connection box 100.

[0098] Moreover, by molding the connecting module and the adapter panel 120 separately, the structure of the molding die can be effectively simplified, the design difficulty of the die can be reduced, and thus the production difficulty of the connecting box 100 can be effectively reduced.

[0099] See also Figure 2 and Figure 3 As shown, the connection box 100 may further include a second connection module 140 and a third connection module 150, which are detachably mounted in the mounting hole 121 via a snap-fit ​​mechanism. The second connection module 140 can be used with the second connector 3 (see reference 121). Figure 6 (as shown) the third connection module 150 can be used to connect with the third connector 4 (see reference 4). Figure 6 (As shown) are connected, and the second connector 3, the third connector 4 and the first connector 2 are different types of fiber optic connectors.

[0100] For example, one of the first connector 2, the second connector 3, and the third connector 4 can be an SC connector, another can be a DLC connector, and yet another can be an MPO connector. Correspondingly, one of the first connection module 130, the second connection module 140, and the third connection module 150 can be an SC adapter, another can be a DLC adapter, and yet another can be an MPO adapter. For example, the first connector 2 can be an SC connector, the second connector 3 can be a DLC connector, and the third connector 4 can be an MPO connector. Correspondingly, the first connection module 130 can be an SC adapter, the second connection module 140 can be a DLC adapter, and the third connection module 150 can be an MPO adapter.

[0101] This allows the connector box 100 to connect to three different fiber optic connectors simultaneously, enabling it to meet the connection requirements of more connector models. This effectively improves the flexibility of the connection between the connector box 100 and the fiber optic connectors, and enhances the versatility of the connector box.

[0102] Of course, in some examples, the adapter panel 120 may be equipped with only two different types of connection modules, so that the connection box 100 can be connected to two different types of fiber optic connectors simultaneously. For example, the two connection modules may be an SC adapter and a DLC adapter, or an SC adapter and an MPO adapter, or a DLC adapter and an MPO adapter. Specifically, the models of each adapter can be flexibly combined according to the specific application scenario, and this application embodiment does not limit this.

[0103] In this embodiment of the application, the specific structure of the connection box 100 provided in this embodiment will be described in detail, taking the first connection module 130 as an SC adapter, the second connection module 140 as a DLC adapter, and the third connection module as an MPO adapter as examples.

[0104] Figure 4 This is a schematic diagram illustrating a connection method between a connection module and an adapter panel from one perspective, provided as an embodiment of this application. Figure 5 This is a schematic diagram illustrating a connection method between a connection module and an adapter panel from another perspective, as provided in an embodiment of this application. Figure 6 This is a schematic diagram of a connector and a connection module connection provided in an embodiment of this application.

[0105] Taking the connection between the first connection module 130 and the adapter panel 120 as an example, for instance, in one possible implementation, see [link to relevant documentation]. Figure 4 and Figure 5As shown, the connecting box 100 may include a first connecting portion 160 disposed on the outside of the adapter panel 120. For example, the first connecting portion 160 may be disposed on the side of the adapter panel 120 facing away from the receiving cavity 111. The first connecting portion 160 may surround the outer periphery of the mounting hole 121, and the first connecting module 130 may be detachably connected to the first connecting portion 160 to achieve a detachable connection with the adapter panel 120.

[0106] For example, a retractable elastic clip (not shown in the figure) may be provided on one end of the first connecting module 130 that extends into the first connecting part 160. An assembly groove (not shown in the figure) that mates with the elastic clip may be provided on the inner wall of the first connecting part 160. The elastic clip can be engaged in the assembly groove so that the first connecting module 130 and the first connecting part 160 can be detachably connected through the engagement between the elastic clip and the assembly groove.

[0107] The first connecting part 160 can be used to connect with the first connector 2 located outside the housing 110.

[0108] For example, combining Figure 6 As shown, the first connector 2 may include a first inner connector 21 located inside the housing 110 and a first outer connector 22 located outside the housing 110. Correspondingly, the second connector 3 may include a second inner connector 31 located inside the housing 110 and a second outer connector 32 located outside the housing 110. The third connector 4 may include a third inner connector 41 located inside the housing 110 and a third outer connector 42 located outside the housing 110. The connection box 100 may also include a beam splitter 180, which may include multiple input terminals and multiple output terminals. One end of the first inner connector 21, the second inner connector 31, and the third inner connector 41 located inside the housing 110 may be connected to the input terminal or the output terminal on the beam splitter 180, respectively, and the other end may be connected to the first connection module 130, the second connection module 140, and the third connection module 150, respectively. So that the first inner connector 21, the second inner connector 31 and the third inner connector 41 located inside the housing 110 can be connected to the first outer connector 22, the second outer connector 32 and the third outer connector 42 located outside the housing 110 through the first connection module 130, the second connection module 140 and the third connection module 150 respectively, so as to realize the transmission of optical signals.

[0109] The first connecting portion 160 on the connecting box 100 can be used to connect with the first external connector 22, the second external connector 32, and the third external connector 42, respectively, and the first connecting portion 160 and the adapter panel 120 can be an integral structure. For example, the first connecting portion 160 and the adapter panel 120 can be formed by integral injection molding or integral stamping to make the first connecting portion 160 and the adapter panel 120 form a whole. This eliminates the need to provide a seal (e.g., a sealing ring) between the first connecting portion 160 and the adapter panel 120.

[0110] In related technologies, a sealing ring (e.g.) is provided between the adapter and the adapter panel. Figure 1 The adapter includes a first sealing ring 14 and a second sealing ring 15 to provide a seal between the adapter panel and the adapter. However, the sealing rings are easily omitted during assembly. Moreover, after prolonged use, the sealing rings are prone to deformation and aging, leading to seal failure and reducing the reliability and stability of the seal between the adapter panel and the adapter.

[0111] In this embodiment, by making the first connecting part 160 and the adapter panel 120 an integrated structure, the reliability and stability of the seal between the connecting module and the adapter panel 120 can be effectively improved, and problems such as seal failure between the connecting module and the adapter panel 120 can be reduced or avoided, thereby effectively improving the sealing performance of the connecting box 100 and enhancing the stability and reliability of the connecting box 100.

[0112] Figure 7 This is a cross-sectional view of a connection module and an adapter panel provided in an embodiment of this application.

[0113] See Figure 7 As shown, the first connection module 130 may include a first inner module 131 and a first outer module 132 that are internally connected; the second connection module 140 may include a second inner module 141 and a second outer module 142 that are internally connected; and the third connection module 150 may include a third inner module 151 and a third outer module 152 that are internally connected. The first inner module 131, the second inner module 141, and the third inner module 151 may extend toward the inner wall of the housing 110, and the first outer module 132, the second outer module 142, and the third outer module 152 may extend toward the outer side of the housing 110.

[0114] Continue to combine Figure 6As shown, the first inner module 131 can be used to connect with the first inner connector 21, and the first outer module 132 can be used to connect with the first outer connector 22, so that the first inner connector 21 located inside the housing 110 and the first outer connector 22 located outside the housing 110 can be connected through the first inner module 131 and the first outer module 132 to realize the transmission of optical signals.

[0115] Correspondingly, the second inner module 141 can be used to connect with the second inner connector 31, and the second outer module 142 can be used to connect with the second outer connector 32, so that the second inner connector 31 located inside the housing 110 and the second outer connector 32 located outside the housing 110 can be connected through the second inner module 141 and the second outer module 142 to realize the transmission of optical signals.

[0116] The third inner module 151 can be used to connect with the third inner connector 41, and the third outer module 152 can be used to connect with the third outer connector 42, so that the third inner connector 41 located inside the housing 110 and the third outer connector 42 located outside the housing 110 can be connected through the third inner module 151 and the third outer module 152 to realize the transmission of optical signals.

[0117] For example, taking the connection between the first inner connector 21 and the first outer connector 22 as an example, optical fibers can be provided in the first inner connector 21 and the first outer connector 22. When the first inner connector 21 and the first outer connector 22 are connected through the first inner module 131 and the first outer module 132, the two optical fibers can be respectively inserted into the first inner module 131 and the first outer module 132 so that the two optical fibers are connected inside the first inner module 131 and the first outer module 132 to realize the transmission of optical signals.

[0118] Correspondingly, the conduction principle between the second inner connector 31 and the second outer connector 32, as well as between the third inner connector 41 and the third outer connector 42, is the same as that between the first inner connector 21 and the first outer connector 22, and will not be repeated here.

[0119] During the use of connector boxes, their specifications vary depending on the application scenario. For example, different exterior colors may be required based on customer customization needs, or different logos or trademarks may need to be designed on the housing or adapter panel. However, in the connector boxes mentioned above, the housing structure is usually fixed. To meet customer customization needs, the corresponding molds need to be redesigned and the connector boxes need to be remanufactured, which results in a long production cycle and high costs, greatly reducing the flexibility of connector box customization.

[0120] In the embodiments of this application, see also Figure 7As shown, the connecting box 100 may also include an identification panel 180, which may be located outside the adapter panel 120. The identification panel 180 may be detachably connected to the housing 110 or the adapter panel 120. For example, the identification panel 180 may be detachably connected to the housing 110 or the adapter panel 120 by means of snap-fit, fastening, adhesive or screw fasteners.

[0121] An clearance hole 181 is provided on the label panel 180 opposite to the mounting hole 121. The first outer module 132, the second outer module 142 and the third outer module 152 can be connected to the outside of the housing 110 through the clearance hole.

[0122] The label panel 180 can be equipped with logos or trademarks. For example, according to the user's needs, specific slogans, symbols, product specifications, or trademarks can be set on the label panel 180. Alternatively, according to the user's customization requirements, the label panel 180 can be set to different colors. In this way, during the customization process, only the label panel 180 needs to be manufactured separately according to the requirements and assembled onto the housing 110 of the connector box 100. There is no need to remake the entire housing 110 of the connector box 100, the adapter panel 120, or the adapter, which can effectively reduce the customization cost of the connector box 100, improve the customization flexibility of the connector box 100, and meet the user's special customization needs.

[0123] Figure 8 This is a schematic diagram illustrating another connection method between a connection module and an adapter panel, provided in an embodiment of this application. Figure 9 This is a front view of another connection method between a connection module and an adapter panel provided in an embodiment of this application. Figure 10 This is a cross-sectional view of a first connection module disposed in an adapter panel, as provided in an embodiment of this application.

[0124] In another possible implementation, continuing with the example of the connection between the first connection module 130 and the adapter panel 120, see [link to relevant documentation]. Figure 8 and Figure 9 As shown, the connecting box 100 may further include a second connecting portion 170 disposed inside the adapter panel 120. For example, the second connecting portion 170 may be located on the side of the adapter panel 120 facing the receiving cavity 111, and the second connecting portion 170 may surround the outer periphery of the mounting hole 121. The second connecting portion 170 may be used to connect with the first inner module 131, so that the first connecting module 130 can be connected to the adapter panel 120 through the second connecting portion 170.

[0125] For example, see Figure 10As shown, the second connecting part 170 and the first connecting part 160 can both be connected to the mounting hole 121. During the installation of the first connecting module 130, the first connecting module 130 can pass through the second connecting part 170, the mounting hole 121 and the first connecting part 160 in sequence, and connect with the second connecting part 170 to realize the connection with the adapter panel 120.

[0126] The second connecting part 170 and the adapter panel 120 can be an integrated structure. For example, the second connecting part 170 and the adapter panel 120 can also be formed by integral injection molding or integral stamping to make the second connecting part 170 and the adapter panel 120 form a whole. This can effectively improve the strength and stability of the connection between the second connecting part 170 and the adapter panel 120, and help improve the reliability and stability of the connection between the connecting module and the adapter panel 120.

[0127] Correspondingly, the second inner module 141 and the third inner module 151 can also be connected to the second connecting part 170 so that the second inner module 141 and the third inner module 151 can be connected to the adapter panel through the second connecting part 170.

[0128] The following section will continue to use the connection between the first connecting module 130 and the second connecting part 170 as an example to introduce the specific structure of the second connecting part 170.

[0129] Figure 11 This is a schematic diagram of the structure of an adapter panel provided in an embodiment of this application. Figure 12 This is a schematic diagram of a set of connection modules provided in an embodiment of this application.

[0130] For example, see Figure 11 and Figure 12 As shown, a locking hole 172 can be provided on the second connecting portion 170, and a first locking portion 1312 can be provided on the first inner module 131 to cooperate with the locking hole 172. The first locking portion 1312 can be locked into the locking hole 172. For example, the locking hole 172 can be provided on the side wall of the second connecting portion 170 and extend from the inner wall to the outer wall of the second connecting portion 170. The first locking portion 1312 can be provided on the outer side of the first inner module 131.

[0131] During the connection process between the first connecting module 130 and the second connecting part 170, the first inner module 131 can be inserted into the second connecting part 170, and the first snap-fit ​​part 1312 can be snapped into the snap hole 172 from the inner wall direction of the second connecting part 170, so that the first connecting module 130 can be connected to the adapter panel 120 through the cooperation of the first snap-fit ​​part 1312 and the snap hole 172. When the connecting module needs to be disassembled, the first snap-fit ​​part 1312 can be pushed out towards the inner wall direction of the second connecting part 170 from the outer wall direction of the second connecting part 170, so that the first snap-fit ​​part 1312 can be disengaged from the snap hole 172. At this time, the first connecting module 130 can be taken out from the second connecting part 170 to complete the disassembly of the connecting module.

[0132] The slot 172 can be located in the axial direction of the second connecting part 170 (i.e. Figure 11 The first connecting module 130 is limited in the axial and circumferential directions of the second connecting part 170, which can prevent the first connecting module 130 from moving in the axial and circumferential directions of the second connecting part 170 and prevent the first connecting module 130 from separating from the adapter panel 120. This can effectively improve the reliability and firmness of the connection between the first connecting module 130 and the adapter panel 120.

[0133] Correspondingly, a first snap-fit ​​portion 1312 can also be provided on the second inner module 141 and the third inner module 151 so that the second inner module 141 and the third inner module 151 can be connected to the second connecting portion 170 through the cooperation of the first snap-fit ​​portion 1312 and the snap-fit ​​hole 172. This will not be elaborated here.

[0134] See also Figure 12 As shown, the first latching portion 1312 can be a cantilever structure to make the first latching portion 1312 elastic. For example, see... Figure 12 As shown, in the first connecting module 130, there can be a gap between the first latching portion 1312 and the outer wall of the first inner module 131. This gap provides space for pressing the first latching portion 1312 when the first connecting module 130 needs to be removed from the second connecting portion 170. This allows the first latching portion 1312 to retract towards the outer wall of the first inner module 131 to disengage from the latch hole 172, thereby facilitating the removal of the first connecting module 130 from the second connecting portion 170.

[0135] Because the structures of the first inner connector 21, the second inner connector 31, and the third inner connector 41 are different—for example, their dimensions in a certain direction may differ—the structures of the first inner module 131, the second inner module 141, and the third inner module 151 will also be different. See, for example, [link to relevant documentation]. Figure 12As shown, the width of the second inner connector 31 is relatively large, which makes the width of the second inner module 141 that mates with it (i.e., Figure 12 The dimensions in the y-direction are also relatively large. For example, the space between the outer wall of the second inner module 141 and the second connecting part 170 is small, making it difficult to provide space for the retraction of the first snap-fit ​​part 1312.

[0136] Therefore, the first latching portion 1312 can be made to lie in the same plane as the side wall of the second inner module 141, and gaps can be made between the three sides of the first latching portion 1312 and the side wall of the second inner module 141, so that the first latching portion 1312 is a cantilever structure. In other words, it can be understood that the first latching portion 1312 is cut from the side wall of the second inner module 141. In this way, when a force is applied to the first latching portion 1312, the first latching portion 1312 can still be retracted towards the inner wall of the second inner module 141, so that the first latching portion 1312 disengages from the latch hole 172, thereby deconnecting the second connecting module 140 from the second connecting portion 170.

[0137] See also Figure 12 As shown, the third inner module 151 is also relatively small in the y direction. Therefore, there can be a gap between the first snap-fit ​​part 1312 and the outer wall of the third inner module 151 to provide space for the retraction of the first snap-fit ​​part 1312, so that the first snap-fit ​​part 1312 on the third inner module 151 can be dislodged from the snap hole 172, thereby allowing the third inner module 151 to be separated from the second connecting part 170, and realizing the disassembly of the third connecting module 150 and the adapter panel 120.

[0138] See also Figure 11 and Figure 12 As shown, a positioning groove 171 can also be provided on the second connecting portion 170, and a positioning block 1311 that cooperates with the positioning groove 171 can be provided on the first inner module 131. The positioning block 1311 can be locked in the positioning groove 171. For example, the positioning groove 171 can be along the axial direction of the second connecting portion 170 (i.e., Figure 11The first connecting module 130 extends in the x-direction, and the opening of the positioning groove 171 can face the end face of the second connecting part 170 away from the adapter panel 120. During the connection process between the first connecting module 130 and the second connecting part 170, the positioning block 1311 on the first connecting module 130 can be aligned with the opening of the positioning groove 171, and then the positioning block 1311 can be inserted into the positioning groove 171 from the opening of the positioning groove 171, so that the first connecting module 130 and the second connecting part 170 are connected. This makes it easier for the workers to find the correct installation position during the assembly process, and can avoid the connection module from being deflected, thus affecting the normal installation of the first connecting module 130 and the adapter panel 120. It can play an effective role in preventing errors, reducing the error rate, and thus effectively improving the assembly efficiency of the connecting box 100.

[0139] For example, see continue. Figure 11 and Figure 12 As shown, two positioning slots 171 can be formed on the second connecting portion 170, and the two positioning slots 171 can be distributed along the circumference of the second connecting portion 170. Correspondingly, two positioning blocks 1311 can be provided on the first inner module 131. During the assembly process, the two positioning blocks 1311 on the first connecting module 130 can be aligned with the two positioning slots 171 respectively, and the two positioning blocks 1311 can be respectively locked in the two positioning slots 171 to improve the error prevention rate.

[0140] Of course, in some examples, the number of positioning slots 171 and positioning blocks 1311 can be more than two. Specifically, the number of positioning slots 171 and positioning blocks 1311 can be selected and set according to the specific application scenario, and this application does not limit it.

[0141] Correspondingly, the second inner module 141 and the third inner module 151 have positioning blocks 1311 that cooperate with the positioning slot 171 to prevent errors during the installation of the second connecting module 140 and the third connecting module 150, which will not be described in detail here.

[0142] See also Figure 11 and Figure 12As shown, the inner wall of the second connecting portion 170 may also have a first cut surface 173, and the locking hole 172 may be formed on the first cut surface 173. The outer side of the first inner module 131 has a second cut surface 1313. During the connection process between the first connecting module 130 and the second connecting portion 170, the first cut surface 173 may fit against the second cut surface 1313. The fit between the first cut surface 173 and the second cut surface 1313 can provide a limit for the first connecting module 130 in the circumferential direction of the second connecting portion 170, which can prevent the connecting module from rotating and improve the reliability and stability of the connection between the first connecting module 130 and the adapter panel 120. Moreover, the first cut surface 173 can also increase the wall thickness of the second connecting portion 170, which can reduce or prevent the locking hole 172 from cracking and improve the structural stability of the locking hole 172, thereby improving the reliability and stability of the connection between the connecting module and the adapter panel 120.

[0143] The second inner module 141 and the third inner module 151 also have corresponding second cut surfaces 1313, which will not be described in detail here.

[0144] See also Figure 11 and Figure 12 As shown in this embodiment, the inner diameter of the second connecting portion 170 can be larger than the diameter of the mounting hole 121, and the portion of the mounting hole 121 protruding from the inner wall of the second connecting portion 170 can form a limiting platform 174 inside the second connecting portion 170. A limiting portion 1314 that cooperates with the limiting platform 174 is provided on the first inner module 131. For example, the outer diameter of the first inner module 131 can be larger than the outer diameter of the first outer module 132, so that the portion of the first inner module 131 protruding from the first outer module 132 can form the limiting portion 1314.

[0145] During the connection process between the first connecting module 130 and the adapter panel 120, the limiting part 1314 on the first connecting module 130 can abut against the limiting platform 174. For example, during assembly, the first connecting module 130 can be inserted into the mounting hole 121 from the opening of the second connecting part 170 towards the receiving cavity 111. When the limiting part 1314 on the first connecting module 130 abuts against the limiting platform 174 in the second connecting part 170, it indicates that the first connecting module 130 is in the axial direction of the mounting hole 121 (i.e., Figure 11 The first connecting module 130 is positioned in the x-direction of the second connecting part 170 by means of the cooperation between the limiting stage 174 and the limiting part 1314. This can limit the first connecting module 130 in the axial direction of the second connecting part 170, thus avoiding the first connecting module 130 from being improperly installed in the axial direction of the second connecting part 170. This helps to improve the installation accuracy of the first connecting module 130, thereby effectively improving the assembly accuracy of the connecting box 100.

[0146] Correspondingly, the second connection module 140 and the third connection module 150 also have limiting parts 1314 to limit the installation of the second connection module 140 and the third connection module 150.

[0147] Figure 13 This is a schematic diagram of another connection module provided in an embodiment of this application.

[0148] Alternatively, in another possible implementation, continuing with the first connection module 130 as an example, the first connection module 130 can also be directly connected to the adapter panel 120, for example, see... Figure 13 As shown, a limiting plate 133 and a retractable spring block 134 can be provided on the first connecting module 130. During the connection process between the first connecting module 130 and the adapter panel 120, the spring block 134 can be pressed to retract it into the first connecting module 130, allowing one end of the first connecting module 130 to pass through the mounting hole 121 and the limiting plate 133 to abut against the adapter panel 120. In this way, the connection between the connecting module and the adapter panel 120 can be achieved through the cooperation of the spring block 134 and the limiting plate 133. Its structure is simple and easy to operate, effectively improving the convenience of assembly between the connecting module and the adapter panel 120, thereby effectively improving the assembly efficiency of the connecting box 100.

[0149] Figure 14 An isometric sectional view of a first connecting module provided in an embodiment of this application.

[0150] See Figure 14 As shown, a second latching portion 1315 can also be provided on the first inner module 131, which can be used to mate with a slot on the first inner connector 21. For example, during the process of connecting the first inner connector 21 and the first inner module 131, the second latching portion 1315 on the first inner module 131 can be latched into the slot, so that the first inner module 131 and the first inner connector 21 can be connected through the cooperation of the second latching portion 1315 and the slot. This can effectively prevent the first inner connector 21 from disengaging from the first inner module 131, and can effectively improve the reliability and stability of the connection between the first inner connector 21 and the first inner module 131, thereby effectively improving the stability of optical signal transmission between the first inner connector 21 and the first outer connector 22.

[0151] When the first inner connector 21 needs to be disassembled, it can be pulled away from the first inner module 131 to make the second snap-fit ​​part 1315 disengage from the slot, thereby separating the first inner connector 21 from the first inner module 131. This can effectively improve the convenience of assembly and disassembly between the first inner connector 21 and the first inner module 131.

[0152] Figure 15 This is a schematic diagram of the structure of a first connection module provided in an embodiment of this application.

[0153] See Figure 15 As shown, a guide block 1321 may also be provided on the first outer module 132, which can be used to mate with the guide groove on the first outer connector 22. For example, the guide block 1321 can be positioned along the axial direction of the first outer module 132 (i.e., Figure 15 Extending in the x-direction, during the connection of the first external connector 22 and the first external module 132, the opening of the guide groove can be aligned with the guide block 1321, and then the first external connector 22 can be pushed so that the guide groove is engaged outside the guide block 1321 and moves along the extension direction of the guide block 1321. This provides guidance for the fit between the first external connector 22 and the first external module 132, preventing the first external connector 22 from deflecting or misaligning during the connection process, and improving the reliability and stability of the fit between the first external connector 22 and the first external module 132.

[0154] Figure 16 This is a schematic diagram of the structure of a second connection module from one perspective, provided in an embodiment of this application. Figure 17 This is a schematic diagram of the structure of a second connection module provided in an embodiment of this application from another perspective.

[0155] See Figure 16 As shown, the second inner module 141 may include a first connecting cavity 1411 and a second connecting cavity 1412, which can be respectively used to mate with two connectors on the second inner connector 31. For example, during the connection process between the second inner connector 31 and the second inner module 141, the two connectors on the second inner connector 31 can be inserted into the first connecting cavity 1411 and the second connecting cavity 1412 respectively, so that the second inner connector 31 can be connected to the second inner module 141 through the mating of the two connectors and the two connecting cavities. This can reduce or avoid the second inner connector 31 from shifting or deviating, and can effectively improve the reliability and stability of the connection between the second inner connector 31 and the second inner module 141.

[0156] Correspondingly, combined Figure 17As shown, two connection cavities are also correspondingly formed on the second outer module 142. For example, the second outer module 142 may include a third connection cavity 1421 and a fourth connection cavity 1422. The third connection cavity 1421 and the fourth connection cavity 1422 can be used to mate with the two connectors on the second outer connector 32, respectively. For example, during the connection process between the second outer connector 32 and the second outer module 142, the two connectors on the second outer connector 32 can be inserted into the third connection cavity 1421 and the fourth connection cavity 1422, respectively. The third connection cavity 1421 can communicate with the first connection cavity 1411, and the fourth connection cavity 1422 can communicate with the second connection cavity 1412. This allows the two connectors on the second outer connector 32 and the two connectors on the second inner connector 31 to connect within the connection cavities to achieve optical signal transmission.

[0157] Figure 18 This is a schematic diagram of the structure of a third connection module from one perspective, provided in an embodiment of this application. Figure 19 This is a schematic diagram of the structure of a third connection module provided in an embodiment of this application from another perspective.

[0158] See Figure 18 As shown, a third latching part 1511 may be provided on the third inner module 151, which can be used to mate with a slot on the third inner connector 41. For example, during the connection process between the third inner connector 41 and the third inner module 151, the third latching part 1511 on the third inner module 151 can be latched into the slot on the third inner connector 41, so that the third inner connector 41 and the third inner module 151 can be connected through the mating of the third latching part 1511 and the slot. This can reduce or avoid the misalignment or displacement of the third inner connector 41, and help improve the reliability and stability of the mating between the third inner connector 41 and the third inner module 151.

[0159] See Figure 19 As shown, a groove 1521 can be formed on the inner wall of one side of the third outer module 152. The groove 1521 can be used to cooperate with the slider on the third outer connector 42. For example, when connecting the third outer connector 42 to the third outer module 152, the side of the third outer connector 42 with the slider can be aligned with the side of the third outer module 152 with the groove 1521, so that the slider of the third outer connector 42 can be located in the groove 1521 during the connection process. This makes it easier for workers to find the correct installation position during assembly, prevents errors, and improves the assembly efficiency between the third outer connector 42 and the third outer module 152.

[0160] Correspondingly, a groove 1521 can also be provided on one side inner wall of the third inner module 151. The groove 1521 on the third inner module 151 can be used to cooperate with the slider on the third inner connector 41 to provide a positional reference for the connection between the third inner connector 41 and the third inner module 151, thereby improving the accuracy of the connection between the third inner connector 41 and the third inner module 151.

[0161] Figure 20 This is a schematic diagram of a rotating slot provided on a first connecting part according to an embodiment of this application.

[0162] See Figure 20 As shown, a rotating slot 161 can be provided on the first connecting portion 160. The rotating slot 161 can be used to engage with the limiting protrusion on the first external connector 22. The rotating slot 161 can engage with the limiting protrusion on the first connecting portion 160 along its axial direction (i.e., axial direction). Figure 20 The x-direction (in the first connection part 160) acts as a limit, preventing the first external connector 22, located outside the housing 110, from moving or deflecting axially. This helps improve the reliability and stability of the connection between the first external connector 22 and the first connection part 160, and enhances the stability and reliability of optical signal transmission between the two connectors inside and outside the housing 110.

[0163] For example, see continue. Figure 20 As shown, the rotating slot 161 may include a first slot 1611 and a second slot 1612 that are connected to each other. The first slot 1611 may extend from the outer end face of the first connecting portion 160 to the second slot 1612, and the second slot 1612 may extend along the outer periphery of the first connecting portion 160. During the process of the connector outside the housing 110 engaging with the first connecting portion 160, the limiting protrusion on the connector may be engaged from the outer end face of the first connecting portion 160 into the first slot 1611, and then through the first slot 1611 into the second slot 1612. Finally, it may rotate around the circumference of the first connecting portion 160 along the extending direction of the second slot 1612 to the end of the second slot 1612. The second slot 1612 can limit the limiting protrusion, preventing the limiting protrusion from moving along the axial direction of the first connecting portion 160 (i.e., ...). Figure 20 The connector moves in the x-direction to avoid axial displacement along the first connection part 160, thereby effectively improving the firmness and reliability of the fit between the connector and the first connection part 160.

[0164] Correspondingly, the second external connector 32 and the third external connector 42 also have limiting protrusions that cooperate with the rotating slot 161, so that the cooperation between the rotating slot 161 and the limiting protrusion can provide a limit for the second external connector 32 and the third external connector 42, thereby improving the reliability and stability of the cooperation between the second external connector 32 and the third external connector 42 and the first connecting part 160.
