[0035] Please refer to Figure 1 The present invention provides a housing assembly 100 of an optical fiber coupling module, which is applied to a semiconductor laser.

[0036] The housing assembly 100 includes a housing 10 and a plug component 20 .

[0037] Please refer to Figure 2 and Figure 3 The housing 10 includes a receiving chamber 11 . A through hole 12 is formed on the side wall of the housing 10 to connect the inside and outside of the receiving chamber 11 .

[0038] The fiber coupling module also includes a laser chip, an optical component, and a fiber assembly 200. The laser chip is used to emit laser light. The optical component is used to guide light. The fiber assembly 200 includes a fiber core 201 and a ferrule 202 surrounding the fiber core 201.

[0039] Specifically, the accommodating cavity 11 is used to accommodate the laser chip and the optical component. The optical component is used to focus the light emitted by the laser and transmit the light to the fiber core 201 for optical coupling.

[0040] Please refer to Figure 1 、 Figure 4 、 Figure 5 and Figure 6 , the plug-in component 20 is detachably arranged in the accommodating cavity 11. In this embodiment, the plug-in direction of the plug-in component 20 is perpendicular to the axis of the through hole 12. The plug-in component 20 includes a groove 21 and a through hole 22 in sequence along the direction from close to the side wall of the shell 10 to away from the side wall of the shell 10. A groove 21 is provided at one end of the plug-in component 20 close to the side wall of the shell 10. One end of the groove 21 extends to the edge of the plug-in component 20 and an opening 213 is provided at the edge of the plug-in component 20. The opening 213 is close to the inner bottom wall of the shell 10. A through hole 22 is provided at one end of the plug-in component 20 away from the side wall of the shell 10. The through hole 22, the groove 21 and the through hole 12 are connected in sequence. The through hole 22 connects the interior of the accommodating cavity 11 with the groove 21.

[0041] It can be understood that by setting the groove 21, when installing or removing the plug-in component 20, the fiber core 201 can move relative to the plug-in component 20 along the extension direction of the groove 21. The groove 21 can avoid the fiber core 201, preventing the plug-in component 20 from colliding with the fiber core 201 and damaging the optical fiber.

[0042] Specifically, the groove 21 includes a first groove section 211 and a second groove section 212. The second groove section 212 extends to the edge of the plug-in component 20 and forms an opening 213 at the edge of the plug-in component 20. The depth of the first groove section 211 is less than the depth of the second groove section 212. The through hole 22, the first groove section 211, and the through hole 12 are sequentially connected.

[0043] It is understood that the first groove section 211 refers to the portion of the groove 21 corresponding to the through hole 22. The second groove section 212 refers to the portion of the groove 21 extending outside the through hole 22. The depth of the groove 21 refers to the distance along the axis of the through hole 22, that is, the distance between the bottom wall of the groove 21 near the through hole 22 and the side wall of the plug-in component 20 near the housing 10.

[0044] Please refer to Figure 3 It is understandable that the ferrule 202 passes through the through hole 12 so that the end of the fiber core 201 passes through the first groove 211 and enters the through hole 22 .

[0045] In this embodiment, the groove 21 is provided on the plug component 20 to facilitate installation and removal of the plug component 20, and to facilitate movement of the fiber core 201 relative to the plug component 20 along the extending direction of the groove 21. Specifically, when removing the plug component 20, the plug component 20 only needs to be pulled out of the housing 10, and the fiber core 201 moves from the first groove 211 to the second groove 212 relative to the plug component 20, and then is removed from the plug component 20 through the opening 213 of the second groove 212. When installing the plug component 20, the plug component 20 is moved toward the housing 10, and the fiber core 201 enters the second groove 212 from the opening 213 relative to the plug component 20, and then enters the first groove 211 from the second groove 212.

[0046] Please combine Figure 3 and Figure 6 Specifically, in the axial direction of the fiber core 201, the end of the fiber core 201 is disposed between the second end 2121 of the second groove section 212, which faces away from the side wall of the housing 10, and the first end 2111 of the first groove section 211, which faces away from the side wall of the housing 10. Furthermore, the second end 2121 is further away from the side wall of the housing 10 than the first end 2111. It will be appreciated that when the connector 20 is mounted on the housing 10, the end of the groove 21 away from the side wall of the housing 10 forms a stepped surface.

[0047] Furthermore, the depth of the second groove 212 is greater than the distance from the end of the fiber core 201 to the inner wall of the housing 10, and the depth of the first groove 211 is less than the distance from the end of the fiber core 201 to the inner wall of the housing 10. It is understood that when the plug component 20 is installed on the housing 10, the sidewall of the plug component 20 abuts against the inner wall of the housing 10, and the distance from the end of the fiber core 201 to the inner wall of the housing 10 is equivalent to the length of the end of the fiber core 201 extending into the groove 21. When the fiber core 201 moves from the second groove 212 into the first groove 211, the end of the fiber core 201 extends out of the first groove 211 and enters the through hole 22. The end of the fiber core 201 can move relative to the plug component 20 between the second groove 212 and the through hole 22. The groove 21 allows the plug-in component 20 and the fiber core 201 to avoid each other during installation or removal, avoiding collision between the plug-in component 20 and the fiber core 201 and preventing damage to the optical fiber; when the optical fiber is burned, it is easy to remove the optical fiber.

[0048] Furthermore, in this embodiment, the through hole 22 is a circular hole. A circular arc surface is provided at one end of the groove 21. Specifically, a circular arc surface is provided at one end of the first section groove 211. It is understood that one end of the first section groove 211 is a semicircular hole, and the groove 21 is a waist-shaped groove. The circular hole, the circular arc surface, and the through hole 12 are coaxially arranged. It is understood that when the plug-in component 20 is installed on the housing 10, after the fiber core 201 extends into the through hole 12, it is located at the center of the first section groove 211, avoiding light leakage due to the opening being too large.

[0049] Please refer to Figure 6 In this embodiment, the diameter of the through hole 22 is greater than the width of the groove 21. Furthermore, the widths of the first section of the groove 211 and the second section of the groove 212 are the same, and the diameter of the through hole 22 is greater than the width of the first section of the groove 211. It can be understood that the width of the groove 21 refers to the distance between the two opposite side walls of the groove 21 parallel to the extension direction of the groove 21. The width of the first section of the groove 211 is the same as the diameter of its arc surface. Specifically, in this embodiment, the diameter of the above-mentioned arc surface is smaller than the diameter of the through hole 22. The through hole 22 and the first section of the groove 211 form a stepped hole structure, which can to a certain extent prevent light from passing through the first section of the groove 211 from the through hole 22 to hit the other side of the plug-in component 20, and reduce the probability of light hitting the glue dispensing position of the ferrule 202 and the fiber core 201. The ferrule 202 and the fiber core 201 are fixed by glue dispensing. It can be understood that in this embodiment, the width of the groove 21 should be slightly larger than the outer diameter of the fiber core 201 and smaller than the outer diameter of the ferrule 202, so that the fiber core 201 can pass through the groove 21 and extend into the conductive hole 22, and the gap between the groove 21 and the fiber core 201 is as small as possible.

[0050] To improve the stability of the plug-in component 20, in this embodiment, the depth of the through hole 22 is greater than the depth of the first section of the groove 211. Alternatively, in other embodiments, the depth of the through hole 22 may be equal to the depth of the first section of the groove 211, as long as the end of the fiber core 201 is located within the through hole 22 when the plug-in component 20 is installed in place.

[0051] Please refer to Figure 2 Furthermore, in this embodiment, a positioning groove 13 is formed on the inner wall of the housing 10. The positioning groove 13 is located within the accommodating cavity 11. The through hole 12 is connected to the positioning groove 13. The plug-in component 20 is installed in the positioning groove 13. It is understood that the shape of the positioning groove 13 is consistent with the shape of the plug-in component 20, so that the plug-in component 20 will not move when installed in the positioning groove 13, and the connection is stable.

[0052] The housing 10 is also provided with a mounting hole 14. The plug-in component 20 includes a plug-in component body 24 and a mounting portion 23. The mounting hole 14 is opened on the mounting portion 23. Specifically, the number of the mounting holes 14 is at least two. It can be understood that the two mounting holes 14 ensure that the relative position of the plug-in component 20 and the housing 10 is fixed. In the present embodiment, the plug-in component 20 is fixedly connected to the housing 10 by a screw. Specifically, the axial direction of the mounting hole 14 is consistent with the plug-in direction of the plug-in component 20. That is, the installation direction of the screw is consistent with the plug-in direction of the plug-in component 20, so as to facilitate installation and disassembly. In the present embodiment, the plug-in component 20 is installed in the positioning groove 13 from one side of the accommodating cavity 11 of the housing 10, and the mounting hole 14 faces the outside of the accommodating cavity 11, so as to facilitate the operation of the screw.

[0053] Specifically, the mounting portion 23 extends toward the outside of the plug-in component 20 body. It is understood that the mounting portion 23 and the plug-in component body 24 form a stepped structure so that when the plug-in component 20 is inserted into the positioning slot 13, the mounting portion 23 abuts against the housing 10, thereby confirming that the plug-in component 20 is properly installed. The plug-in component 20 is then secured to the housing 10 using screws.

[0054] In order to prevent the screw head from protruding from the mounting portion 23 , in this embodiment, a countersunk hole 231 is defined on the mounting portion 23 .

[0055] It will be appreciated that in this embodiment, the installation portion 23 and the installation hole 14 enable a detachable connection between the plug component 20 and the housing 10. When optical coupling is required, the plug component 20 is installed on the housing 10 and operation is performed. When the operation is completed, the plug component 20 can be removed to quickly check whether the fiber core 201 is dirty and then clean it. After cleaning, the plug component 20 is reinstalled and operation can continue.

[0056] In summary, the housing assembly 100 for the optical fiber coupling end provided by the embodiment of the present invention has the following beneficial effects:

[0057] The housing assembly 100 includes a housing 10 and a plug-in component 20. The housing 10 includes a housing cavity 11. A through hole 12 communicating with the housing cavity 11 is formed on the side wall of the housing 10. The plug-in component 20 is detachably disposed within the housing cavity 11. A groove 21 is formed at one end of the plug-in component 20, which is adjacent to the side wall of the housing 10. One end of the groove 21 extends to the edge of the plug-in component 20 and an opening 213 is provided at the edge of the plug-in component 20. A through hole 22 is formed at one end of the plug-in component 20, which is away from the side wall of the housing 10. The through hole 22, the groove 21, and the through hole 12 are sequentially connected.

[0058] By providing a through hole 22 and a groove 21 that are sequentially connected, the present invention allows the fiber core 201 of the optical fiber assembly 200 to pass through the groove 21 and into the through hole 22. The through hole 22 is used for lighting. By providing the groove 21, the fiber core 201 can move relative to the plug-in component 20 along the extension direction of the groove 21 when installing or removing the plug-in component 20. The groove 21 can avoid the fiber core 201, preventing the plug-in component 20 from colliding with the fiber core 201 and damaging the optical fiber. The plug-in component 20 is easy to disassemble, making it convenient to clean the optical fiber. The present invention is easy to disassemble, making it easy to clean the optical fiber, avoiding damage to the optical fiber during installation and removal, and facilitating the removal of the optical fiber if it burns. Before fully inspecting the lens inside the housing assembly 100, an air gun must be used to blow the housing assembly 100 to remove particles and other dirt inside the housing 10, which has a certain chance of causing contamination at the optical fiber receiving end. By unplugging the plug-in component 20, the optical fiber can be cleaned in the next step, thereby reducing costs, manpower, and material resources.

[0059] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
