Description

Technical Field

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

[0002] Optical distribution network (ODN) refers to a network consisting of all passive optical fibers and passive devices (such as optical splitters) between optical line terminals (OLT) and optical network units (ONU). ODN connects an OLT device and multiple ONU devices to provide bidirectional transmission of optical signals. In optical distribution network projects, connection boxes (such as optical cross-connect boxes, optical distribution boxes, optical fiber splitter boxes, etc.) are usually used to connect optical fibers to achieve network transmission.

[0003] Specifically, an adapter is usually provided on the connection box, and the two ends of the adapter are respectively connected to two optical fiber connectors. By plugging the two optical fiber connectors at the two ends of the adapter, the two sections of optical fiber can be connected. The connection box usually includes a shell and a panel. The shell and the panel are detachably connected by a snap-on method. The adapter is usually integrally formed on the panel. A sealing ring is provided between the shell and the panel to achieve sealing between the shell and the panel.

[0004] However, in the above-mentioned connection box, the sealing reliability between the shell and the panel is poor, and the flexibility of the adapter is low. Utility Model Content

[0005] The embodiment of the present application provides a connection box, which can effectively improve the reliability of the shell sealing and enhance the flexibility of the adapter.

[0006] The present application provides a connection box, including a shell and an adapter module; the shell includes a first shell and a second shell, the first shell and the second shell are jointly arranged to form a accommodating cavity; one of the first shell and the second shell has a mounting hole, and the adapter module is detachably connected to the mounting hole; the adapter module includes a first end and a second end opposite to each other, the first end of the adapter module is inserted into the mounting hole and communicated with the outside of the shell through the mounting hole, and the second end of the adapter is located in the accommodating cavity; the first end of the adapter module is used to cooperate with a first connector outside the shell, and the second end of the adapter module is used to cooperate with a second connector inside the shell; the first shell and the second shell are sealed and connected by welding.

[0007] The embodiment of the present application makes a welding connection between the first shell and the second shell, and the sealing of the welding connection is reliable and not easy to fail, which can effectively reduce or avoid the problems of sealing failure between the first shell and the second shell, thereby effectively improving the reliability and stability of the sealing between the first shell and the second shell. Moreover, by making the adapter module detachably connected to the shell, when the connection box needs to be docked with a connector of a different model, the adapter module can be disassembled and replaced with an adapter module of the corresponding model without replacing the entire shell, which can effectively improve the flexibility of the adapter module.

[0008] In a possible implementation, the first shell is an upper shell, the second shell is a lower base plate, the mounting hole is located on the first shell, and the adapter module is detachably connected to the first shell.

[0009] In one possible implementation, the adapter module includes a connecting plate and a plurality of adapter bodies located on the connecting plate; the first shell has a plurality of mounting holes, the plurality of adapter bodies are respectively detachably connected to the plurality of mounting holes, and the connecting plate is located in the accommodating cavity and is detachably connected to the outer shell.

[0010] The connecting plate can integrate the various adapter bodies together to improve the integration of the adapter module. During the assembly process of the adapter module and the shell, all the adapter bodies can be assembled on the shell by simply following the assembly steps in sequence. There is no need to assemble each adapter body separately. This can effectively simplify the assembly operation of the adapter module and improve the assembly efficiency of the adapter module, thereby effectively improving the assembly efficiency of the connection box.

[0011] In one possible implementation, the first shell includes a top wall and side walls surrounding the top wall, and the adapter module is located on the side walls; the top wall has a first limiting portion, and one of the connecting plate and the first limiting portion has a first limiting groove, and the other slot of the connecting plate and the first limiting portion is in the first limiting groove.

[0012] The cooperation between the first limiting portion and the first limiting groove can effectively improve the reliability and firmness of the connection between the connecting plate and the first housing, can effectively reduce or prevent the adapter module from falling off the housing, and help improve the reliability and stability of the adapter in the housing, thereby effectively improving the overall structural stability of the connection box. Moreover, the cooperation between the first limiting groove and the first limiting portion can provide a limit for the connecting plate, can prevent the connecting plate from deflecting in the first direction, can effectively improve the assembly accuracy of the adapter module in the first direction, thereby effectively improving the overall assembly accuracy of the connection box.

[0013] In a possible implementation, the connecting plate is provided with the first limiting groove, and a portion of the first limiting portion is clamped in the first limiting groove.

[0014] In one possible implementation, the second shell has a second limiting portion, the second limiting portion has a second limiting groove, and part of the first limiting portion is clamped in the second limiting groove. In this way, the assembly between the first shell and the second shell can be limited in the first direction to reduce or avoid the misalignment between the second shell and the first shell in the first direction, thereby improving the assembly accuracy between the first shell and the second shell in the first direction. Moreover, it can also effectively reduce or avoid the misalignment between the first shell and the second shell during the welding process, prevent the misalignment of the first shell and the second shell from affecting the welding between the first shell and the second shell, and help improve the welding accuracy between the first shell and the second shell.

[0015] The connecting plate is in contact with the second limiting portion, which can provide limiting for the assembly between the adapter module and the second housing in the second direction and the third direction, thereby improving the assembly accuracy of the adapter in the second direction and the third direction. Moreover, it can also reduce or avoid the displacement or misalignment of the adapter module during subsequent use, and can effectively improve the reliability and stability of the adapter module in the housing.

[0016] In a possible implementation, the second limiting portion has a first abutting surface, the first abutting surface faces the side wall direction of the first shell, and the connecting plate abuts on the first abutting surface. The first abutting surface can improve the assembly accuracy of the adapter module in the second direction, thereby effectively improving the assembly accuracy of the connection box as a whole. Moreover, the first abutting surface can also prevent the adapter module from being offset or moved in the second direction, which helps to improve the reliability and stability of the adapter module in the shell, thereby effectively improving the structural stability of the connection box as a whole.

[0017] In a possible implementation, the second limiting portion further has a second abutting surface, the second abutting surface faces the top wall direction of the first shell, and the connecting plate also abuts on the second abutting surface. The second abutting surface can improve the assembly accuracy of the adapter module in the third direction, thereby effectively improving the assembly accuracy of the connection box as a whole. Moreover, the second abutting surface can also prevent the adapter module from shifting or moving in the third direction, which helps to improve the reliability and stability of the adapter module in the shell, thereby effectively improving the structural stability of the connection box as a whole.

[0018] In one possible implementation, the second limiting portion includes a first limiting plate and a second limiting plate, the first limiting plate and the second limiting plate are parallel to each other and spaced apart, and the space between the first limiting plate and the second limiting plate forms the second limiting groove.

[0019] In a possible implementation, at least one of the first shell and the second shell has a welding protrusion, and the welding protrusion melts to form a connecting weld between the first shell and the second shell. The welding protrusion can increase the size of the connecting weld between the first shell and the second shell, and can increase the contact area between the first shell and the second shell and the connecting weld, and can effectively reduce or avoid disconnection between the first shell and the second shell, thereby effectively improving the firmness and reliability of the connection between the first shell and the second shell.

[0020] In a possible implementation, the adapter body includes a first mating portion and a second mating portion connected to each other. The first mating portion is inserted into the mounting hole and communicates with the outside of the housing, the diameter of the second mating portion is larger than the diameter of the mounting hole, and the second mating portion abuts against the outer circumference of the mounting hole. The first mating portion is used to mate with a first connector outside the housing, and the second mating portion is used to mate with a second connector inside the housing.

[0021] The cooperation between the second matching portion and the outer periphery of the mounting hole can limit the installation of the adapter module on the first shell, which can improve the assembly accuracy of the adapter module on the first shell, thereby effectively improving the overall assembly accuracy of the connection box.

[0022] In one possible implementation, a third limiting groove is provided on one of the first matching portion and the mounting hole, and a third limiting portion that matches the third limiting groove is provided on the other of the first matching portion and the mounting hole; the third limiting portion is located in the third limiting groove to limit the relative rotation between the first matching portion and the mounting hole.

[0023] The cooperation between the third limiting portion and the third limiting groove can prevent errors in the assembly of the adapter module and the first housing, which helps to improve the accuracy of the assembly between the adapter module and the first housing. Moreover, the cooperation between the third limiting portion and the third limiting groove can provide circumferential limitation for the adapter body, which can reduce or avoid the displacement of the adapter body in its circumferential direction, which helps to improve the reliability and stability of the assembly between the adapter module and the first housing.

[0024] In a possible implementation, the third limiting groove is located on the inner wall of the mounting hole, and the third limiting portion is located on the outer side of the first matching portion.

[0025] In a possible implementation, the housing further comprises a connection portion, which is located outside the housing and surrounds the outer periphery of the mounting hole; the connection portion is used to connect to a first connector located outside the housing. This can reduce or avoid the separation of the first connector and the adapter module, help improve the reliability and stability of the matching between the adapter module and the first connector, and thus effectively improve the reliability and stability of signal transmission between the adapter module and the first connector.

[0026] In a possible implementation, the connection portion and the housing are an integrated structure. The integrated structure has reliable sealing and is not prone to failure, which can effectively improve the sealing between the connection portion and the housing. Moreover, there is no need to provide a structural member (for example, a sealing ring, etc.) for connection and sealing between the connection portion and the first housing, which can save the assembly of the sealing structure and the connection structure, effectively simplifying the assembly process of the connection box and reducing the production cost of the connection box.

[0027] In a possible implementation, the connection portion has a locking groove, and the locking groove is used to cooperate with the locking column on the first connector. The cooperation between the locking groove and the locking column can improve the firmness and reliability of the connection box between the first connector and the connection portion, and can effectively reduce or avoid separation between the first connector and the connection portion, thereby effectively improving the reliability and stability of the cooperation between the first connector and the adapter module.

[0055] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0056] OLT and ONU refer to the connection devices in the optical transmission network, and are two essential modules in the 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.

[0057] In ODN projects, a large number of box-type devices such as optical cross-connect boxes, optical distribution boxes, and optical fiber splitter boxes are used, and different numbers and types of passive optical devices are integrated in these devices to meet the needs of optical fiber deployment and management. These box-type devices are generally equipped with adapters, and the two connectors are positioned in the sleeves of the adapter to achieve the docking of two sections of optical fiber.

[0058] In the related art, the connection box usually includes a shell, a panel and an adapter. The shell and the panel are detachably connected by snapping, and the adapter is usually integrally formed on the panel. A sealing ring is provided between the shell and the panel, and the sealing ring is used to provide a seal between the shell and the panel to improve the sealing inside the shell. Among them, the adapter is usually integrally formed on the panel.

[0059] However, in the above-mentioned connection box, the housing and the panel are sealed by a sealing ring, which is prone to failure, thereby reducing the reliability of the seal between the housing and the panel.

[0060] Moreover, the adapter and the panel are an integrated structure. When the connection box needs to be matched with a connector of a different model, the panel and the adapter need to be remade, which has a high replacement cost and poor flexibility.

[0061] In addition, the sealing ring between the shell and the panel needs to be customized, which is relatively expensive and increases the production cost of the connection box.

[0062] In order to solve the above problems, the researchers improved the connection box by making a welding connection between the first shell and the second shell. The sealing of the welding connection is reliable and not easy to fail, which can effectively reduce or avoid the problems of sealing failure between the first shell and the second shell, thereby effectively improving the reliability and stability of the seal between the first shell and the second shell. Moreover, by making the adapter module detachable and connected to the shell, when the connection box needs to be connected to a connector of a different model, the adapter module can be disassembled and replaced with an adapter module of the corresponding model without replacing the entire shell, which can effectively improve the flexibility of the adapter module.

[0063] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are 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 those skilled in the art without creative work are within the scope of protection of the present application.

[0064] It should be noted that the "box" mentioned in the present application does not limit the size and appearance of the embodiments of the present application. The connection box provided in the embodiments of the present application can be a box-type device such as an optical cross-connection box, an optical distribution box, an optical fiber splitter box, etc., or it can be a product with the characteristics of a switching element directly molded on any shell.

[0065] The embodiment of the present application provides a connection box, which can be an optical cross-connection box, an optical distribution box, an optical fiber splitter box, or other box-type equipment, or a product with switching component characteristics directly molded on any shell. In the embodiment of the present application, the connection box will be described as an optical fiber splitter box.

[0066] Figure 1 A schematic diagram of the structure of a connection box provided in an embodiment of the present application, Figure 2 An exploded view of a connection box provided in an embodiment of the present application, Figure 3 A schematic diagram of the structure of a connection box and a connector provided in an embodiment of the present application.

[0067] The present application provides a connection box 100, see Figure 1 and Figure 2 As shown, the connection box 100 may include a housing 110 and an adapter module 120 disposed on the housing 110. The housing 110 may include a first shell 111 and a second shell 112. The first shell 111 and the second shell 112 may be jointly surrounded to form a receiving cavity 113 (see Figure 4As shown in FIG. 1 , one of the first housing 111 and the second housing 112 may have a mounting hole 1111, and the adapter may be detachably connected to the mounting hole 1111. For example, the adapter module 120 may be detachably connected to the mounting hole 1111 by means of snap connection, buckle connection, etc.

[0068] See also Figure 3 As shown, the adapter module 120 may include a first end 121 and a second end 122 opposite to each other, the first end 121 may be inserted into the mounting hole 1111 and communicated with the outside of the housing 110 through the mounting hole 1111, and the second end 122 may be located in the accommodating cavity 113 of the housing 110. Other devices for realizing the complete functions of the connection box 100 may also be arranged in the accommodating cavity 113 of the housing 110, for example, a splitter, an optical fiber tray, an optical fiber connector, etc. may also be arranged in the accommodating cavity 113.

[0069] The first end 121 of the adapter module 120 can be used to connect with the first connector 200 outside the housing 110, and the second end 122 of the adapter module 120 can be used to connect with the second connector 300 inside the housing 110. For example, the adapter module 120 can be a fiber optic adapter, and the first connector 200 and the second connector 300 can both be fiber optic connectors. The first connector 200 and the second connector 300 can be connected through the adapter module 120, so that the optical fibers inside the first connector 200 and the second connector 300 can be docked through the adapter module 120 to achieve transmission of optical signals.

[0070] For example, a positioning sleeve 125 may be provided in the adapter module 120, and optical fibers may be provided in the first connector 200 and the second connector 300. During the process of connecting the first connector 200 and the second connector 300 with the adapter module 120, the optical fibers in the first connector 200 and the second connector 300 may be respectively inserted into the positioning sleeves 125 in the adapter module 120, so that the two optical fibers can be coaxially connected through the positioning sleeve 125, thereby enabling optical signals to be transmitted between the two optical fibers.

[0071] For example, the first connector 200 and the second connector 300 may be SC connectors (square connector; SC for short), and accordingly, the adapter module 120 may be an SC adapter module 120. Alternatively, the first connector 200 and the second connector 300 may also be DLC connectors (double lucent connector; DLC for short), and accordingly, the adapter module 120 may be a DLC adapter module 120. Alternatively, in some examples, the first connector 200 and the second connector 300 may also be MPO connectors (multi-fiber pull off; MPO for short), and accordingly, the adapter module 120 may be an MPO adapter module 120. In the embodiments of the present application, the specific models of the adapter module 120, the first connector 200, and the second connector 300 are not limited.

[0072] The model of the adapter module 120 can be selected and set according to the model of the optical fiber connector that cooperates with it. For example, when the adapter module 120 needs to cooperate with the SC connector, the SC adapter module can be assembled in the mounting hole 1111. When the adapter module 120 needs to cooperate with the DLC connector, the SC adapter module on the housing 110 can be removed, and then the DLC adapter module can be assembled so that the adapter module 120 can cooperate with the DLC connector. Alternatively, when the adapter module 120 needs to cooperate with the MPO connector, the DLC adapter module on the housing 110 can be removed, and then the MPO adapter module can be assembled so that the adapter module 120 can cooperate with the MPO connector. Through the detachable connection between the adapter module 120 and the mounting hole 1111 on the housing 110, the model and specification of the adapter module 120 can be flexibly selected so that the adapter module 120 can meet the connection requirements of connectors of different models.

[0073] The first shell 111 and the second shell 112 in the housing 110 can be sealed and connected by welding. For example, the first shell 111 and the second shell 112 can be connected by laser welding, ultrasonic welding, hot plate welding, etc. For example, the adapter module 120 and the components in the housing 110 (for example, a splitter, a fiberboard, and a second connector 300, etc.) can be assembled on the first shell 111 or the second shell 112, and then the second connector 300 in the first shell 111 can be connected to the adapter module 120. After the assembly of the components inside the housing 110 and the assembly between the internal components and the adapter module 120 are completed, the first shell 111 can be installed on the second shell 112, and then the first shell 111 and the second shell 112 are welded, so that the first shell 111 and the second shell 112 are sealed and connected by welding.

[0074] For example, the connecting weld between the first shell 111 and the second shell 112 can be a continuous weld to fill the gap between the first shell 111 and the second shell 112, so that the first shell 111 and the second shell 112 can be surrounded by a sealed accommodating cavity 113 to reduce or avoid external water stains or stains from entering the accommodating cavity 113 of the outer shell 110. This can effectively improve the cleanliness of the accommodating cavity 113, prevent water stains from entering the accommodating cavity 113 and affecting the normal operation of the connection box 100, and can effectively improve the reliability and stability of the connection box 100.

[0075] Compared with the solution in the related art of achieving sealing between shells through sealing strips, the present application realizes a welding connection between the first shell 111 and the second shell 112. The welding connection has reliable sealing and is not prone to failure. It can effectively reduce or avoid problems such as sealing failure between the first shell 111 and the second shell 112, thereby effectively improving the reliability and stability of the sealing between the first shell 111 and the second shell 112.

[0076] Moreover, the first shell 111 and the second shell 112 are sealed and connected by welding, which can eliminate the need to set a sealing ring between the first shell 111 and the second shell 112, and eliminate the cost of customizing and assembling the sealing ring, which can effectively reduce the overall production cost of the connection box 100.

[0077] In addition, compared with the solution in which the adapter is integrally formed with the shell, by making the adapter module 120 detachably connected to the shell 110, when the connection box 100 needs to be docked with a connector of a different model, the adapter module 120 can be disassembled and replaced with an adapter module 120 of the corresponding model without replacing the entire shell, which can effectively improve the flexibility of the adapter module 120.

[0078] Figure 4 A cross-sectional view of a connection box provided in an embodiment of the present application.

[0079] See also Figure 4 As shown, the first housing 111 may be an upper housing, the second housing 112 may be a lower base plate, the mounting hole 1111 may be provided on the first housing 111, and the adapter module 120 may be detachably connected to the first housing 111 through the mounting hole 1111. When a different adapter module 120 needs to be replaced, the adapter module 120 may be removed from the first housing 111, and then replaced with an adapter module 120 of a corresponding model, so as to improve the flexibility of the connection box 100.

[0080] Alternatively, in some examples, the first housing 111 may also be a side housing, the second housing 112 may be an adapter panel, the mounting hole 1111 may be provided on the adapter panel, and the adapter module 120 may be detachably connected to the adapter panel through the mounting hole 1111. When a different adapter module 120 needs to be replaced, the adapter module 120 may be removed from the adapter panel, and then replaced with an adapter module 120 of a corresponding model. In the embodiment of the present application, the first housing 111 is an upper housing, the second housing 112 is a lower base plate, and the adapter is detachably connected to the first housing 111 as an example for explanation.

[0081] Continue to see Figure 4 As shown, a welding protrusion 1115 may be provided on one of the first shell 111 and the second shell 112, and the welding protrusion 1115 may be melted to form a connecting weld between the first shell 111 and the second shell 112. For example, the welding protrusion 1115 may be as shown in FIG. Figure 4 On the first shell 111 shown in the figure, for example, the welding protrusion 1115 can be arranged on the surface where the first shell 111 contacts the second shell 112. Alternatively, the welding protrusion 1115 can also be arranged on the second shell 112, and the welding protrusion 1115 can be located on the surface where the second shell 112 contacts the first shell 111. Alternatively, in some examples, the welding protrusion 1115 can be arranged on both the first shell 111 and the second shell 112. The following description is made by taking the welding protrusion 1115 located on the first shell 111 as an example.

[0082] During the welding process, the welding protrusion 1115 can be melted, and the melted welding protrusion 1115 can fill the contact area between the first shell 111 and the second shell 112, and the melted welding protrusion 1115 can be bonded to the second shell 112, so that the first shell 111 and the second shell 112 can be connected through the melted welding protrusion 1115.

[0083] The welding protrusion 1115 can increase the size of the connecting weld between the first shell 111 and the second shell 112, can improve the contact area between the first shell 111 and the second shell 112 and the connecting weld, can effectively reduce or avoid the disconnection between the first shell 111 and the second shell 112, thereby effectively improving the firmness and reliability of the connection between the first shell 111 and the second shell 112.

[0084] Figure 5 A schematic diagram of the structure of an adapter module provided in an embodiment of the present application.

[0085] See also Figure 5As shown, the adapter module 120 may include a connecting plate 123 and a plurality of adapter bodies 124 located on the connecting plate 123. A plurality of mounting holes 1111 may be provided on the first shell 111. The plurality of adapter bodies 124 may be detachably connected to the plurality of mounting holes 1111, respectively. The connecting plate 123 may be located in the accommodating cavity 113 and detachably connected to the outer shell 110.

[0086] For example, the housing 110 (e.g., the first housing 111 and the second housing 112) and the connecting plate 123 may have matching structural parts, and the connecting plate 123 and the housing 110 may be detachably connected through the matching between the structural parts. This can effectively reduce or avoid the separation of the adapter module 120 and the housing 110, and help improve the reliability and stability of the connection between the adapter module 120 and the housing 110.

[0087] The connecting plate 123 can integrate the various adapter bodies 124 together to improve the integration of the adapter module 120. During the assembly of the adapter module 120 and the shell 110, all the adapter bodies 124 can be assembled on the shell 110 by simply performing the assembly steps in sequence. There is no need to assemble each adapter body 124 separately, which can effectively simplify the assembly operation of the adapter module 120 and improve the assembly efficiency of the adapter module 120, thereby effectively improving the assembly efficiency of the connection box 100.

Figure 7 As shown, the adapter module 120 can be located on the side wall 1113 of the first shell 111. For example, the first shell 111 can have four side walls 1113 connected in sequence, and the adapter module 120 can be located on one of the side walls 1113. The side wall 1113 where the adapter module 120 is located can be a transfer panel.

[0090] The top wall 1112 may have a first limiting portion 1114, one of the connecting plate 123 and the first limiting portion 1114 may have a first limiting groove 1231, and the other of the connecting plate 123 and the first limiting portion 1114 may be clamped in the first limiting groove 1231. For example, the first limiting groove 1231 may be as follows: Figure 5 As shown in FIG. 1 , the connecting plate 123 is opened. Figure 7As shown, at least a portion of the first limiting portion 1114 can be clamped in the first limiting groove 1231 on the connecting plate 123 , so that the connecting plate 123 can be connected to the first shell 111 by cooperating with the first limiting portion 1114 .

[0091] Alternatively, in some examples, the first limiting groove 1231 may also be provided on the first limiting portion 1114, and the connecting plate 123 may be clamped in the first limiting groove 1231 on the first limiting portion 1114, so that the connecting plate 123 may be connected to the first housing 111 by cooperating with the first limiting groove 1231. The following description will be made by taking the first limiting groove 1231 provided on the connecting plate 123 as an example.

[0092] The cooperation between the first limiting portion 1114 and the first limiting groove 1231 can effectively improve the reliability and firmness of the connection between the connecting plate 123 and the first shell 111, can effectively reduce or avoid the adapter module 120 from falling off the shell 110, and help to improve the reliability and stability of the adapter in the shell 110, thereby effectively improving the overall structural stability of the connection box 100.

[0093] Moreover, the cooperation between the first limiting groove 1231 and the first limiting portion 1114 can provide a limit for the connecting plate 123, thereby preventing the connecting plate 123 from being moved in the first direction (i.e. Figure 7 The offset occurs in the x direction in the first direction, which can effectively improve the assembly accuracy of the adapter module 120 in the first direction, thereby effectively improving the overall assembly accuracy of the connection box 100.

[0094] Figure 8 A schematic diagram of the structure of the adapter module, the first shell and the second shell provided in an embodiment of the present application.

[0095] See also Figure 8 As shown, the second housing 112 may have a second limiting portion 1121, the second limiting portion 1121 may have a second limiting groove 1122, a portion of the first limiting portion 1114 may be clamped in the second limiting groove 1122, and the connecting plate 123 may abut against the second limiting portion 1121. For example, during the assembly process, the adapter module 120 may be connected to the first housing 111 first, and the connecting plate 123 in the adapter module 120 may be clamped and matched with the first limiting portion 1114 on the first housing 111.

[0096] After the adapter module 120 and the first housing 111 are assembled, the second housing 112 and the first housing 111 can be assembled. For example, the first limiting portion 1114 on the first housing 111 can be clamped in the second clamping groove on the second housing 112 to provide a limiting effect on the assembly between the first housing 111 and the second housing 112, so that the first housing 111 and the second housing 112 are pre-connected, and then the first housing 111 and the second housing 112 are welded. In addition, the connecting plate 123 can abut against the second limiting portion 1121 to provide a limiting effect between the adapter module 120 and the second housing 112.

[0097] The cooperation between the first limiting portion 1114 and the second limiting portion 1121 can be used to assemble the first shell 111 and the second shell 111 in the first direction (i.e. Figure 8 A limit is provided in the x direction in the first direction to reduce or avoid misalignment between the second shell 112 and the first shell 111 in the first direction, thereby improving the assembly accuracy between the first shell 111 and the second shell 112 in the first direction.

[0098] Moreover, the cooperation between the first limiting portion 1114 and the second limiting portion 1121 can also effectively reduce or avoid the misalignment of the first shell 111 and the second shell 112 during the welding process, prevent the first shell 111 and the second shell 112 from being misaligned and affecting the welding between the first shell 111 and the second shell 112, and help to improve the welding accuracy between the first shell 111 and the second shell 112, thereby effectively improving the overall production accuracy of the connection box 100.

[0099] The abutment between the connecting plate 123 and the second limiting portion 1121 can be used as the assembly between the adapter module 120 and the second housing 112 in the second direction (ie Figure 8 y direction in the middle) and the third direction (i.e. Figure 8 A limit is provided in the z direction) in which the first direction can be perpendicular to the second direction, and the third direction can be perpendicular to both the first direction and the second direction. This can improve the assembly accuracy of the adapter in the second direction and the third direction, thereby effectively improving the assembly accuracy between the adapter module 120 and the housing 110.

[0100] Moreover, the abutment between the connecting plate 123 and the second limiting portion 1121 can also reduce or avoid the displacement or misalignment of the adapter module 120 during subsequent use, which can effectively improve the reliability and stability of the adapter module 120 in the housing 110, thereby effectively improving the overall structural stability of the connection box 100.

[0101] Fig. 9A schematic structural diagram of the cooperation between an adapter module and a second shell provided in an embodiment of the present application.

[0102] For example, see Fig. 9 As shown, the second limiting portion 1121 may have a first abutting surface 11211, and the first abutting surface 11211 may face the side wall 1113 of the first shell 111, that is, face the side wall 1113 of the first shell 111. Fig. 9 In the y direction, the connecting plate 123 can abut against the first abutting surface 11211 of the second limiting portion 1121. For example, a side of the connecting plate 123 facing away from the side wall 1113 of the first shell 111 can abut against the first abutting surface 11211. The first abutting surface 11211 can be Fig. 9 A limit is provided for the connecting plate 123 in the y direction in order to limit the movement of the connecting plate 123 in the second direction.

[0103] For example, during the assembly of the second housing 112 and the first housing 111, the first limiting portion 1114 on the first housing 111 can be clamped in the second limiting groove 1122 on the second limiting portion 1121 to limit the movement of the second housing 112 in the first direction. The second housing 112 can move along the second direction. During the movement of the second housing 112 along the second direction, when the connecting plate 123 abuts against the first abutting surface 11211 on the second limiting portion 1121, it indicates that the second housing 112 has moved to a suitable position. At this time, the welding operation between the first housing 111 and the second housing 112 can be performed.

[0104] The first abutting surface 11211 can improve the assembly accuracy of the adapter module 120 in the second direction, thereby effectively improving the assembly accuracy of the connection box 100 as a whole. Moreover, the first abutting surface 11211 can also prevent the adapter module 120 from deflecting or moving in the second direction, which helps to improve the reliability and stability of the adapter module 120 in the housing 110, thereby effectively improving the overall structural stability of the connection box 100.

[0105] Continue to see Fig. 9 As shown, the second limiting portion 1121 may also have a second abutting surface 11212, and the second abutting surface 11212 may face the top wall 1112 of the first shell 111, that is, toward Fig. 9 In the z direction, the connecting plate 123 can also abut against the second abutting surface 11212. For example, the side of the connecting plate 123 facing away from the top wall 1112 of the first shell 111 (i.e., the lower end face of the connecting plate 123) can abut against the second abutting surface 11212. The second abutting surface 11212 can be Fig. 9 A limit is provided for the connecting plate 123 in the z direction) to limit the movement of the connecting plate 123 in the third direction.

[0106] For example, during the assembly of the second housing 112 and the first housing 111, the second housing 112 can move along the third direction. During the movement of the second housing 112 along the third direction, when the connecting plate 123 abuts against the second abutting surface 11212 on the second limiting portion 1121, it means that the second housing 112 moves to a suitable position in the third direction. At this time, the welding operation between the first housing 111 and the second housing 112 can be performed.

[0107] The second abutting surface 11212 can improve the assembly accuracy of the adapter module 120 in the third direction, thereby effectively improving the assembly accuracy of the connection box 100 as a whole. Moreover, the second abutting surface 11212 can also prevent the adapter module 120 from deflecting or moving in the third direction, which helps to improve the reliability and stability of the adapter module 120 in the housing 110, thereby effectively improving the overall structural stability of the connection box 100.

[0108] Fig.10 A schematic structural diagram of a second shell provided in an embodiment of the present application.

[0109] See also Fig.10 As shown, the second limiting portion 1121 may include a first limiting plate 11213 and a second limiting plate 11214. The first limiting plate 11213 and the second limiting plate 11214 may be parallel to each other and spaced apart. The space between the first limiting plate 11213 and the second limiting plate 11214 may form a second limiting groove 1122. For example, the first limiting portion 1114 may be a plate-like structure. During the assembly process of the second shell 112 and the first shell 111, the first limiting portion 1114 on the first shell 111 may be inserted into the second limiting groove 1122 between the first limiting plate 11213 and the second limiting plate 11214. The first limiting plate 11213 and the second limiting plate 11214 may limit and block the first limiting portion 1114 to limit the second shell 112 in the first direction (i.e. Fig.10 Movement in the x direction) in the first direction can effectively improve the assembly accuracy of the first shell 111 and the second shell 112 in the first direction, and improve the welding accuracy between the first shell 111 and the second shell 112, thereby effectively improving the overall production accuracy of the connection box 100.

[0110] Fig.11 A schematic structural diagram of a first shell provided in an embodiment of the present application at another viewing angle.

[0111] See also Fig.11As shown, the housing 110 may also be provided with a connection portion 1117, which may be located outside the housing 110 and arranged around the outer periphery of the mounting hole 1111, and the connection portion 1117 may be used to connect with the first connector 200 outside the housing 110. For example, mutually matching connection structures may be respectively provided on the connection portion 1117 and the first connector 200, so that the connection portion 1117 may be connected with the first connector 200. In this way, the separation of the first connector 200 and the adapter module 120 may be reduced or avoided, which helps to improve the reliability and stability of the matching between the adapter module 120 and the first connector 200, thereby effectively improving the reliability and stability of signal transmission between the adapter module 120 and the first connector 200.

[0112] Continue to see Fig.11 As shown, the connecting portion 1117 may have a locking groove 11171, and the locking groove 11171 may be used to cooperate with the locking column on the first connector 200. For example, the locking groove 11171 may be as shown in FIG. Fig.11 As shown in the figure, the first connector 200 may be provided with a locking cap on the outer periphery of the connecting portion 1117, and the locking column may be located on the inner wall of the locking cap. During the connection between the first connector 200 and the adapter module 120, the locking cap may be sleeved on the connecting portion 1117, and the locking column on the inner wall of the locking cap may be located in the locking groove 11171 on the connecting portion 1117.

[0113] The cooperation between the locking groove 11171 and the locking column can improve the firmness and reliability of the connection box 100 between the first connector 200 and the connecting part 1117, and can effectively reduce or avoid the separation between the first connector 200 and the connecting part 1117, thereby effectively improving the reliability and stability of the cooperation between the first connector 200 and the adapter module 120.

[0114] The connection part 1117 and the housing 110 may be an integrated structure. For example, taking the connection part 1117 being located in the first housing 111 as an example, the connection part 1117 and the first housing 111 may be formed by integral injection molding or integral stamping, so that the connection part 1117 and the first housing 111 are an integral body. The integrated structure has reliable sealing and is not prone to failure, which can effectively improve the sealing between the connection part 1117 and the housing 110. Moreover, in this way, there is no need to set a structural member (for example, a sealing ring, etc.) for connection and sealing between the connection part 1117 and the first housing 111, which can save the assembly of the sealing structure and the connection structure, can effectively simplify the assembly process of the connection box 100, and reduce the production cost of the connection box 100.

[0115] For example, the connection portion 1117 and the housing 110 may be made of relatively low-cost plastic material to reduce the production cost of the housing 110 and the connection portion 1117 .

[0116] Fig.12 A schematic diagram of the structure of an adapter body and a first shell provided in an embodiment of the present application. Fig.13 for Fig.12 Magnified view of area A in the middle.

[0117] See also Fig.12 and Fig.13 As shown, the adapter body 124 may include a first mating portion 1241 and a second mating portion 1242. The first mating portion 1241 may be inserted into the mounting hole 1111 and communicate with the outside of the housing 110. For example, the first mating portion 1241 may pass through the mounting hole 1111 and extend into the connecting portion 1117. The diameter of the second mating portion 1242 may be greater than the diameter of the mounting hole 1111. The second mating portion 1242 may abut against the outer periphery of the mounting hole 1111. The first mating portion 1241 may be used to mate with the first connector 200 outside the housing 110, and the second mating portion 1242 may be used to mate with the second connector 300 inside the housing 110.

[0118] The portion of the second mating portion 1242 whose diameter is larger than the mounting hole 1111 can form a limit platform. During the assembly of the adapter module 120 and the first shell 111, the first mating portion 1241 can penetrate into the mounting hole 1111 from the inner side of the first shell 111 and extend to the outside of the outer shell 110. When the limit platform on the second mating portion 1242 abuts against the outer periphery of the mounting hole 1111, it indicates that the adapter module 120 is installed in a suitable position.

[0119] The cooperation between the second mating portion 1242 and the outer periphery of the mounting hole 1111 can limit the installation of the adapter module 120 on the first shell 111, thereby improving the assembly accuracy of the adapter module 120 on the first shell 111, thereby effectively improving the overall assembly accuracy of the connection box 100.

[0120] Continue to see Fig.13 As shown, one of the first matching portion 1241 and the mounting hole 1111 may have a third limiting groove 1116, and the other of the first matching portion 1241 and the mounting hole 1111 may have a third limiting portion 12411 that matches the third limiting groove 1116. For example, the third limiting groove 1116 may be as shown in FIG. Fig.13As shown, the third limiting portion 12411 is opened on the inner wall of the mounting hole 1111 and extends to the inner wall of the connecting portion 1117. The third limiting portion 12411 can be located on the outer side of the first matching portion 1241 so that the matching between the third limiting groove 1116 and the third limiting portion 12411 provides circumferential limitation for the adapter body 124.

[0121] The third limiting portion 12411 may be located in the third limiting groove 1116, and the cooperation between the third limiting portion 12411 and the third limiting groove 1116 may limit the relative rotation between the first matching portion 1241 and the mounting hole 1111. For example, in the process of assembling the adapter module 120 and the first housing 111, the third limiting portion 12411 may be aligned with the third limiting groove 1116 first, and then the first matching portion 1241 of the adapter body 124 may be inserted into the mounting hole 1111. In the process of the first matching portion 1241 extending into the mounting hole 1111, the third limiting portion 12411 may slide in the third limiting groove 1116.

[0122] The cooperation between the third limiting portion 12411 and the third limiting groove 1116 can prevent errors in the assembly of the adapter module 120 and the first housing 111, which helps to improve the accuracy of the assembly between the adapter module 120 and the first housing 111. Moreover, the cooperation between the third limiting portion 12411 and the third limiting groove 1116 can provide circumferential limiting for the adapter body 124, which can reduce or avoid the displacement of the adapter body 124 in its circumferential direction, which helps to improve the reliability and stability of the assembly between the adapter module 120 and the first housing 111.

[0123] Alternatively, in some examples, the third limiting groove 1116 may also be provided on the outer side of the first matching portion 1241, and the third limiting portion 12411 may be located on the inner wall of the mounting hole 1111, so that the cooperation between the third limiting groove 1116 and the third limiting portion 12411 provides circumferential limiting for the adapter body 124. Specifically, the arrangement positions of the third limiting portion 12411 and the third limiting groove 1116 may be selected and set according to specific application scenarios.
