Description

Technical Field

[0001] This application relates to the field of optical communication device technology, and more specifically, to a tray device for a multi-module optical emission sub-module assembly. Background Technology

[0002] The Optical Transmitter Submodule (TOSA), as a core component of the optical transmission module, plays a crucial role in converting electrical signals into optical signals. Its typical structure consists of an adapter, a sleeve, and a laser: the adapter acts as a fiber optic interface to achieve optical path coupling; the sleeve is used for the precision assembly of the laser and the optical fiber; and the laser completes the electro-optic conversion through coaxial encapsulation. In existing technologies, because the adapter, sleeve, and laser are all independent circular cross-section components, assembly relies solely on simple mechanical connections, resulting in significant technical drawbacks: the overall installation process depends on manual alignment, making it impossible to achieve rapid positioning through mechanical structures and difficult to guarantee the accuracy of batch repetitive assembly. These problems directly lead to low component yield and limited production efficiency. Especially in mass production scenarios, the positioning defects of traditional structures significantly increase debugging time and scrap costs. Currently, the industry urgently needs an integrated solution that can simultaneously solve batch production, precise positioning, and achieve rapid assembly. Existing technologies urgently need improvement to address these issues. Utility Model Content

[0003] The purpose of this application is to provide a tray device for optical emission sub-module components with multiple modules, which has the advantages of improving assembly accuracy, realizing stable parallel assembly of multiple components, and rapid assembly.

[0004] This application provides a tray device for a multi-module optical emission sub-module assembly, including an optical emission sub-module assembly. The optical emission sub-module assembly has a mounting plate on its outer periphery. The mounting plate is embedded in a limiting groove on the surface of the tray. The tray surface has two or more limiting grooves arranged horizontally and vertically at intervals. An optical emission sub-module assembly is installed in each limiting groove. The optical emission sub-module assembly includes an adapter, a sleeve, and a laser connected in sequence. The cross-section of the adapter, sleeve, and laser is circular. The bottom of the limiting groove has a positioning hole, and the inner wall of the positioning hole is connected to the adapter.

[0005] The mounting plate has a raised mounting seat on its surface. The mounting hole inside the mounting seat is used to connect to a sleeve. The outer diameter of the sleeve is larger than the outer diameter of the adapter, and the outer diameter of the mounting hole is also larger than the outer diameter of the adapter. The outer diameter of the mounting hole is smaller than the outer diameter of the laser.

[0006] The mounting base has positioning columns on both sides that are higher than the mounting base. The positioning columns have horizontal holes in the horizontal direction, and the surface of the mounting plate has vertical holes.

[0007] The mounting base is located on one side of the two positioning columns, and a protruding second limiting block is provided on the other side of the two positioning columns. The second limiting block is at a different height from the mounting base, and a second vertical hole is provided on the surface of the second limiting block.

[0008] As can be seen from the above, the optical emission sub-module component tray device provided in this application achieves precise axial alignment of the optical emission sub-module component and the adapter through the cooperative positioning structure of the limiting groove and the positioning hole. Combined with the multi-dimensional arrangement of the limiting groove, it effectively solves the problems of manual assembly deviation and batch production error, and has the advantages of improving assembly accuracy and realizing the parallel and stable assembly of multiple components.

[0014] The following will refer to the appendix to this application. Figure 1-4The technical solutions in this application are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application. It should be noted that similar reference numerals and letters in the following drawings indicate similar items; therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0015] In existing technologies, the optical emission submodule, as a core component of the optical transmission module, relies on manual alignment of the circular cross-sectional parts of the adapter, sleeve, and laser during assembly. This makes it difficult to control the accuracy of repeated assembly during mass production. Traditional structures lack mechanical positioning design, increasing debugging time and limiting yield rates. Especially in scenarios where multiple components need to be installed simultaneously, manual operation is inefficient and prone to errors.

[0016] To address these issues, researchers discovered that coaxial positioning of circular cross-section components is key to achieving rapid assembly. Analysis revealed that by implementing a standardized positioning structure on the tray, enabling the adapter, sleeve, and laser to form a self-aligning mechanism, manual intervention can be eliminated. Further research showed that by using a mounting plate and limiting groove to create spatial constraints, combined with positioning holes for axial fixation, a basic architecture for parallel installation of multiple modules can be constructed.

[0017] Therefore, this application proposes a tray device for a multi-module optical emission sub-module assembly, including an optical emission sub-module assembly. The optical emission sub-module assembly has a mounting plate 10 on its outer periphery. The mounting plate 10 is embedded in a limiting groove 3 on the surface of the connecting tray 1. The surface of the tray 1 has two or more limiting grooves 3 arranged horizontally and vertically at intervals. Each limiting groove 3 is fitted with an optical emission sub-module assembly. The optical emission sub-module assembly includes an adapter 14, a sleeve 13, and a laser 4 connected in sequence. The adapter, sleeve, and laser all have circular cross-sections. The bottom of the limiting groove 3 has a positioning hole 2, and the inner wall of the positioning hole 2 is fitted with the adapter 14.

[0018] The mounting plate refers to the supporting structure that carries the light-emitting sub-module component. It can be made from a metal stamping or injection-molded part, and its edge shape matches the contour of the limiting groove to restrict the horizontal displacement of the component. The limiting groove is a recessed structure on the surface of the tray, which can be formed by CNC milling. Its horizontal and vertical arrangement can form a matrix layout to simultaneously accommodate multiple components and maintain relative positional accuracy. The positioning hole is a through hole or blind hole at the bottom of the limiting groove, which can be implemented using a stepped hole structure. Its inner diameter forms an interference fit or clearance fit with the outer diameter of the adapter to constrain the axial position of the adapter and transmit assembly stress.

[0019] Specifically, after the mounting plate is embedded in the limiting groove, its edge contacts the groove wall to form a planar positioning, preventing the components from shifting laterally on the tray surface. When the adapter is inserted into the positioning hole, its outer wall contacts the hole wall to complete coaxial positioning, while the sleeve and laser achieve a self-centering effect due to their diameter difference. The horizontally and vertically arranged limiting grooves allow multiple components to be installed at preset intervals, forming a standardized layout and facilitating a unified operating procedure during batch assembly.

[0020] Compared to existing technologies, traditional solutions rely on manual adjustment of the coaxiality of circular components, while this solution achieves automatic positioning through the mechanical constraints of the limiting groove and positioning hole, eliminating manual alignment errors. In existing technologies, components are prone to displacement due to vibration after installation; the embedded connection between the mounting plate and the limiting groove in this solution enhances structural stability.

[0021] Through the above technical solution, this application achieves rapid batch installation of optical emission submodule components. By replacing manual alignment with a mechanical positioning structure, assembly efficiency is improved and the yield rate is controllable. The matrix arrangement of components on the tray provides a unified benchmark for subsequent testing or debugging, reducing rework caused by positioning deviations. The fit between the adapter and the positioning holes effectively disperses assembly stress, preventing performance degradation of the laser due to uneven stress.

[0022] This application further proposes that the surface of the mounting plate 10 is provided with a raised mounting seat 5, and the mounting hole inside the mounting seat 5 is used to connect the sleeve 13. The outer diameter of the sleeve 13 is larger than the outer diameter of the adapter 14, and the outer diameter of the mounting hole is also larger than the outer diameter of the adapter 14. The outer diameter of the mounting hole is smaller than the outer diameter of the laser 4.

[0023] The mounting base refers to a raised structure on the surface of the mounting plate, which can be made of metal or engineering plastic through machining. The mounting hole inside is used to fix the axial position of the sleeve. The outer diameter of the mounting hole is designed to be larger than the outer diameter of the adapter, which can be achieved through precision turning or injection molding, allowing the adapter to be directly inserted into the mounting hole without interference. The outer diameter of the sleeve and the inner diameter of the mounting hole form a clearance fit to ensure the concentricity of the sleeve and the mounting hole. The outer diameter of the mounting hole is smaller than the outer diameter of the laser 4 to achieve axial restraint, preventing the laser 4 from passing through the mounting hole.

[0024] Specifically, the mounting base provides vertical support to the sleeve through a raised structure, and the mating relationship between the mounting hole and the sleeve allows the sleeve to automatically achieve radial positioning upon insertion. Since the outer diameters of both the mounting hole and the sleeve are larger than the adapter's outer diameter, the adapter can only mate with the positioning hole during installation, while the sleeve is confined within the mounting hole, forming a layered installation structure. Thus, the assembly sequence of the adapter and sleeve is mechanically constrained, avoiding potential component misalignment or inversion issues that may occur during manual operation.

[0025] Compared to existing technologies, traditional assembly methods rely on operators visually aligning the axes of the sleeve and adapter. This solution, however, utilizes the dimensional difference between the mounting base and the mounting hole, ensuring the sleeve can only be installed along a preset path, achieving self-alignment without manual intervention. Existing technologies lack physical isolation between the adapter and sleeve's mounting positions, while this solution uses the difference in outer diameter to create a natural boundary structure, eliminating the possibility of mis-installation of components.

[0026] Through the above technical solution, this application achieves rapid layered positioning of the sleeve and adapter, solving the problem of low efficiency in manual alignment. The clearance fit between the mounting hole and the sleeve ensures the coaxiality of the components.

[0027] This application further proposes that the mounting base 5 has positioning columns 9 on both sides that are higher than the mounting base 5, the positioning columns 9 have horizontal holes 11 in the horizontal direction, and the mounting plate 10 has vertical holes 6 on its surface.

[0028] The positioning posts are columnar structures vertically positioned on both sides of the mounting base. They can be made of metal or plastic and manufactured through injection molding or machining. They are used to vertically constrain the installation position of the light-emitting sub-module components. The horizontal holes are horizontal channels penetrating the positioning posts. They can be through holes or threaded holes and are used to insert positioning pins or fastening bolts for horizontal fixation. The vertical holes are holes perpendicular to the surface of the mounting plate. They can be threaded holes or plain holes and are used to securely connect the mounting plate to the tray using screws.

[0029] Through the above technical solution, this application solves the technical problem that the optical emission submodule component is prone to horizontal displacement. By using the mechanical limiting structure of vertical and horizontal holes to achieve bidirectional positioning, the relative positions of each component are kept consistent during batch assembly, thereby improving assembly efficiency and product yield.

[0030] As a preferred structural feature, the mounting base 5 is located on one side of the two positioning columns 9, and the other side of the two positioning columns 9 is provided with a protruding second limiting block 7. The second limiting block 7 is at a different height from the mounting base 5, and the surface of the second limiting block 7 is provided with a second vertical hole 8.

[0031] The second limiting block refers to a protruding structure asymmetrically positioned with respect to the mounting base. It can be manufactured using a stepped molding process, creating multiple levels of limiting surfaces through height differences. The second vertical hole refers to a vertical through-hole located on the surface of the second limiting block.

[0032] Specifically, during the assembly of the optical emission submodule, the positioning post achieves horizontal constraint through its horizontal holes and external pins, while the mounting plate achieves vertical positioning through its vertical holes. A height difference between the second limiting block and the mounting base creates a stepped fit between the sleeve and the adapter in the axial direction. The second vertical holes are staggered, increasing the space utilization of the fixing points. During assembly, after the mounting plate is embedded in the limiting groove, the horizontal and vertical holes of the positioning post form a three-dimensional positioning reference. The second limiting block guides the axial alignment of the sleeve and adapter through the height difference, and the second vertical holes provide auxiliary fixing points to prevent component deflection.

[0033] Through the above technical solution, this application achieves precise three-dimensional spatial positioning of the optical emission submodule component, eliminating manual alignment errors. The cooperation between the positioning column and the horizontal hole ensures that the component does not shift horizontally, the staggered distribution of the vertical hole and the second vertical hole enhances vertical stability, and the height difference design of the second limiting block enables components of different diameters to achieve a self-centering effect. This structure ensures that all components maintain a consistent installation posture during batch assembly, significantly improving assembly efficiency and product consistency.

[0034] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
