[0043] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0044] Please refer to Figure 1-Figure 6 The present invention provides a housing assembly 100, which is applied to a fiber coupling module of a semiconductor laser.

[0045] The housing assembly 100 includes a housing 10 and a plug component 20 .

[0046] The housing 10 includes a housing cavity 11. A through hole 12 is provided on the side wall of the housing 10 to connect the inside and outside of the housing cavity 11. It can be understood that the housing cavity 11 is used to accommodate the laser chip and the optical component. The through hole 12 is used to pass through the optical fiber component 30 so that the end of the optical fiber component 30 enters the housing cavity 11. The laser chip is used to emit light. The optical component is used to converge and transmit light to the optical fiber component 30 for optical coupling.

[0047] Specifically, the optical fiber assembly 30 in this embodiment includes a fiber core 31 and a core insert 32 for wrapping the fiber core 31. The core insert 32 extends through the through hole 12 into the accommodating cavity 11. One end of the fiber core 31 extends out of the core insert 32, and is partially exposed outside the core insert 32 for receiving light emitted by the optical assembly.

[0048] The plug-in component 20 is detachably disposed in the accommodating cavity 11 and is disposed near the through hole 12. The plug-in component 20 includes a first module 211 and a second module 212 that rotate relatively. The first module 211 and the second module 212 can be separated or closed. When the first module 211 and the second module 212 are closed, a first through hole 214 is formed. The first through hole 214 is connected to the through hole 12. It can be understood that when the plug-in component 20 is installed in the accommodating cavity 11, the portion of the fiber core 31 that exposes the ferrule 32 is located in the first through hole 214. The first module 211 and the second module 212 are separated, thereby forming a gap on the plug-in component 20. When the plug-in component 20 moves, the fiber core 31 is given way to avoid collision between the plug-in component 20 and the fiber core 31. When the plug-in component 20 is installed, the first module 211 and the second module 212 are closed, and the first through hole 214 wraps the fiber core 31.

[0049] Specifically, the plug-in component 20 is disposed at the optical fiber assembly 30, and is used to surround the portion of the optical fiber assembly 30 extending into the accommodating cavity 11. The plug-in component 20 includes a first portion 21 close to the side wall of the housing 10 and a second portion 22 away from the side wall of the housing 10. It can be understood that when the plug-in component 20 is installed in place, the first portion 21 is located between the second portion 22 and the side wall of the housing 10.

[0050] Further, the plugging direction of the plug-in component 20 is perpendicular to the axis of the through hole 12. It can be understood that the plugging direction of the plug-in component 20 is perpendicular to the axis of the optical fiber assembly 30. In this embodiment, the plug-in direction of the plug-in component 20 is vertically inserted into the housing 10 from top to bottom. In other embodiments, the plug-in direction of the plug-in component 20 can be any direction in the vertical plane, for example, the plug-in direction is inclined.

[0051] In this embodiment, when the plug-in component 20 is inserted into the accommodating cavity 11 on the housing 10 , the plug-in component 20 is fixed to the housing 10 by screws, so that the plug-in component 20 is detachable.

[0052] Specifically, the first part 21 includes a first module 211 and a second module 212. The first module 211 and the second module 212 are both rotatably connected to the second part 22, and the first module 211 and the second module 212 can be separated or closed. When the first module 211 and the second module 212 are closed, a first through hole 214 is formed. The second part 22 is provided with a second through hole 221 that is connected to the first through hole 214. The fiber core 31 in this embodiment extends into the first through hole 214.

[0053] Specifically, in the present embodiment, the first module 211 and the second module 212 are both provided with first half holes 213 opposite to each other, so that when the first module 211 and the second module 212 are closed, the two first half holes 213 form a first through hole 214. In other embodiments, the openings on the first module 211 and the second module 212 can be provided as needed, for example, one-third of the first through hole 214 can be provided on the first module 211, and two-thirds of the first through hole 214 can be provided on the second module 212. As long as the first module 211 and the second module 212 form a complete first through hole 214 when they are closed, the present invention is not limited thereto.

[0054] Optionally, in this embodiment, the rotation center of the first module 211 and the second part 22 coincides with the rotation center of the second module 212 and the second part 22. Specifically, a rotating shaft 24 is fixed to the second part 22. The first module 211 and the second module 212 are rotatably connected to the rotating shaft 24, respectively. In other embodiments, the rotation centers of the first module 211, the second module 212 and the second part 22 can be set separately. For example, two rotating shafts 24 are fixed to the second part 22, which are rotatably connected to the first module 211 and the second module 212, respectively. As long as the first module 211 and the second module 212 can be separated or closed, the present invention is not limited thereto.

[0055] In this embodiment, in order to prevent light from passing through the first through hole 214 from the second through hole 221 and hitting the connection between the fiber core 31 and the ferrule 32, causing burning of the optical fiber, the diameter of the first through hole 214 is smaller than the diameter of the second through hole 221. In this embodiment, the optical fiber assembly 30 includes a fiber core 31 and a ferrule 32 wrapped around the outer wall of the fiber core 31. One end of the fiber core 31 is exposed from the ferrule 32. The end face of the end of the fiber core 31 extending into the first through hole 214 is the end face of the optical fiber coupling end. The diameter of the first through hole 214 is slightly larger than the diameter of the fiber core 31 and smaller than the diameter of the ferrule 32, so that the ferrule 32 abuts against the outer side of the first through hole 214, and the fiber core 31 can extend into the first through hole 214 and enter the second through hole 221.

[0056] It is understandable that the first through hole 214 and the second through hole 221 form a stepped hole. Light entering from the second through hole 221 will not or will not easily enter the first through hole 214, thereby preventing the optical fiber from being burned. Light from the second through hole 221 will not hit the ferrule 32 at the other end of the first through hole 214 from one end of the first through hole 214.

[0057] It is understood that when the plug-in component 20 is installed, the first module 211 and the second module 212 are separated. The plug-in component 20 is moved so that the fiber core 31 moves relative to the plug-in component 20 in the gap between the first module 211 and the second module 212 until the fiber core 31 enters between the first half holes 213. The first module 211 and the second module 212 are closed, so that the fiber core 31 is clamped in the first through hole 214. When the plug-in component 20 is removed, the first module 211 and the second module 212 are separated. The plug-in component 20 is moved so that the fiber core 31 moves relative to the plug-in component 20 from between the first half holes 213 to the gap between the first module 211 and the second module 212, and then the first module 211 and the second module 212 are closed, so that the plug-in component 20 is removed, so that the fiber core 31 of the optical fiber assembly 30 is exposed, and then the end face of the optical fiber coupling end of the plug core 32 close to the fiber core 31 can be cleaned.

[0058] Specifically, the shell assembly 100 also includes a driving column 13, which is used to drive the first module 211 and the second module 212 to separate. The driving column 13 is fixed on the side wall of the shell 10. The driving column 13 and the through hole 12 are arranged in sequence along the plug-in direction of the plug-in component 20. In this embodiment, the driving column 13 is arranged above the through hole 12. Correspondingly, a clearance hole 216 is also formed when the first module 211 and the second module 212 are closed. The clearance hole 216 is used to cooperate with the driving column 13 so that the first module 211 and the second module 212 are closed. The clearance hole 216 and the first through hole 214 are arranged in sequence along the plug-in direction of the plug-in component 20. It can be understood that when the plug-in component 20 is installed on the shell 10, the driving column 13 is located in the clearance hole 216.

[0059] It is easy to understand that by arranging the driving column 13 and the through hole 12 in sequence along the plug-in direction of the plug-in component 20, when the plug-in component 20 is installed, the driving column 13 first contacts the first module 211 and the second module 212, thereby separating the first module 211 and the second module 212 first, so that the distance between the first module 211 and the second module 212 at the end near the first through hole 214 is greater than the distance near the end near the make way hole 216, that is, the gap between the first module 211 and the second module 212 is fan-shaped, thereby preventing the first module 211 and the second module 212 from colliding with the fiber core 31 and causing damage to the fiber core 31.

[0060] Specifically, in this embodiment, the first module 211 and the second module 212 are both provided with a second half hole 215. When the first module 211 and the second module 212 are closed, the two second half holes 215 form a clearance hole 216. In other embodiments, the openings on the first module 211 and the second module 212 can be arranged as needed, for example, one-third of the clearance hole 216 can be arranged on the first module 211, and two-thirds of the clearance hole 216 can be arranged on the second module 212. As long as the complete clearance hole 216 is formed when the first module 211 and the second module 212 are closed, the present invention is not limited to this.

[0061] When installing the plug-in component 20, the plug-in component 20 is inserted into the corresponding arrangement on the housing 10. The first module 211 and the second module 212 first contact the drive column 13. Under the downward pressure of the plug-in component 20, the first module 211 and the second module 212 are spread apart by the drive column 13, so that the first module 211 and the second module 212 are separated. The drive column 13 first enters between the two first half holes 213, and the first module 211 and the second module 212 are separated from the contact with the drive column 13. Under the action of gravity, the first module 211 and the second module 212 are closed. Then, the drive column 13 continues to contact the first module 211 and the second module 212, and the first module 211 and the second module 212 are spread apart. When the drive column 13 enters between the two second half holes 215, the first module 211 and the second module 212 are closed again, so that the first through hole 214 below surrounds the optical fiber coupling end, and the upper clearance hole 216 surrounds the drive column 13, and the installation is completed.

[0062] Similarly, when the plug component 20 is disassembled, the plug component 20 is pulled out in a direction away from the housing 10. The first module 211 and the second module 212 are separated under the action of the driving column 13, so that the plug component 20 can be pulled out.

[0063] In order to prevent the first module 211 and the second module 212 from contacting the fiber core 31 when being pulled out, in this embodiment, the outer diameter of the driving column 13 is larger than the outer diameter of the fiber core 31, and the gap between the accommodating hole 216 and the driving column 13 is smaller than the gap between the first through hole 214 and the fiber core 31. It can be understood that when moving the same distance, the driving column 13 first contacts the first module 211 and the second module 212, so that the first module 211 and the second module 212 are separated before contacting the fiber core 31.

[0064] In order to facilitate the driving column 13 to open the first module 211 and the second module 212, in this embodiment, the edges of the first half hole 213 and the second half hole 215 are provided with rounded corners. It can be understood that during the movement of the plug-in component 20, the driving column 13 and the rounded corners can slide relative to each other to prevent the driving column 13 from being unable to be inserted between the first module 211 and the second module 212.

[0065] Furthermore, in order to facilitate the driving column 13 to enter the gap between the first module 211 and the second module 212 when installing the plug-in component 20, in this embodiment, the ends of the first module 211 and the second module 212 are relatively provided with chamfers, so that the two chamfers form an opening when the first module 211 and the second module 212 are closed. It can be understood that when the plug-in component 20 is installed, the driving column 13 first contacts the two chamfers, thereby applying pressure to both sides of the first module 211 and the second module 212, thereby spreading the first module 211 and the second module 212 apart.

[0066] Furthermore, in this embodiment, a concave cavity 222 is provided on the second part 22, facing the side wall of the housing 10. A top edge 223, a first side edge 224 and a second side edge 225 located on both sides of the top edge 223 are provided around the concave cavity 222. The first module 211 and the second module 212 are located in the concave cavity 222. It can be understood that the concave cavity 222 is a three-sided surrounding structure, and an opening is provided below the concave cavity 222, so that the core 31 of the optical fiber assembly 30 can enter the first part 21 from the opening. The first module 211 is spaced apart from the top edge 223 and the first side edge 224. The second module 212 is spaced apart from the top edge 223 and the second side edge 225.

[0067] Specifically, the first module 211 is provided with a first inclined surface 2111 spaced apart from the top edge 223 and a second inclined surface 2112 spaced apart from the first side edge 224. The second module 212 is provided with a third inclined surface 2121 spaced apart from the top edge 223 and a fourth inclined surface 2122 spaced apart from the second side edge 225. In this embodiment, the first module 211 and the second module 212 are substantially symmetrically arranged triangles, that is, the first inclined surface 2111 and the third inclined surface 2121 are symmetrically arranged relative to the fitting surface of the first module 211 and the second module 212, and the second inclined surface 2112 and the fourth inclined surface 2122 are symmetrically arranged relative to the fitting surface of the first module 211 and the second module 212. In other embodiments, the inclination angles of the first inclined surface 2111 and the third inclined surface 2121 can be set to be different, so that the first inclined surface 2111 and the third inclined surface 2121 are asymmetrical relative to the fitting surface of the first module 211 and the second module 212. The inclination angles of the second inclined surface 2112 and the fourth inclined surface 2122 can be set to be different, so that the second inclined surface 2112 and the fourth inclined surface 2122 are asymmetric relative to the fitting surfaces of the first module 211 and the second module 212. As long as the first module 211 and the top edge 223 do not contact the first side edge 224, and the second module 212 and the top edge 223 do not contact the second side edge 225, the present invention is not limited to this.

[0068] When the first module 211 rotates relative to the second part 22 and the distance between the first module 211 and the second module 212 is the largest, the first inclined surface 2111 is in contact with or spaced from the top edge 223, and the second inclined surface 2112 is in contact with or spaced from the first side edge 224. When the second module 212 rotates relative to the second part 22 and the distance between the first module 211 and the second module 212 is the largest, the third inclined surface 2121 is in contact with or spaced from the top edge 223, and the fourth inclined surface 2122 is in contact with or spaced from the second side edge 225. It can be understood that the first module 211 and the second module 212 rotate relative to the second part 22 through the action of the driving column 13, and the first module 211 and the second module 212 are always in contact with the driving column 13. When the distance between the driving column 13 and the rotating shaft 24 is the smallest and just does not enter the clearance hole 216, the distance between the first module 211 and the second module 212 is the largest. At this time, it is necessary to ensure that the first inclined surface 2111 is just in contact with the top edge 223 or is spaced from the top edge 223, and the second inclined surface 2112 is just in contact with the first side edge 224 or is spaced from the second side edge 225; the third inclined surface 2121 is just in contact with the top edge 223 or is spaced from the top edge 223, and the fourth inclined surface 2122 is just in contact with the second side edge 225 or is spaced from the second side edge 225. Ensure that the first module 211 and the second module 212 can rotate to the maximum angle, so that the drive column 13 can enter the clearance hole 216 to complete the installation or removal of the plug-in component 20. When the first module 211 and the second module 212 rotate to the maximum angle, the drive column 13 is located at the lower side of the clearance hole 216 and is infinitely close to the clearance hole 216.

[0069] Furthermore, in order to reduce the outer rotation range of the first module 211 and the second module 212, a first transition surface 2113 is provided between the first inclined surface 2111 and the second inclined surface 2112, and a second transition surface 2123 is provided between the third inclined surface 2121 and the fourth inclined surface 2122. Specifically, the first transition surface 2113 and the second transition surface 2123 are arc surfaces.

[0070] Optionally, in this embodiment, the first side 224 and the second side 225 are both vertical planes. The top edge 223 includes two inclined surfaces, which are inclined upward relative to the first side 224 and the second side 225, respectively, to increase the volume of the first activity cavity and the third activity cavity. In other embodiments, the top edge 223 can be set as a plane, and the two ends are respectively set perpendicular to the first side 224 and the second side 225.

[0071] Furthermore, in this embodiment, an elastic member 23 is also included. The elastic member 23 is disposed between the second portion 22 and the first module 211, and between the second portion 22 and the second module 212. It can be understood that the elastic member 23 provides the first module 211 and the second module 212 with a tendency to close inwards.

[0072] Optionally, in this embodiment, the elastic member 23 is a spring. In other embodiments, the elastic member 23 may be other components, such as a torsion spring, which is disposed at the rotating shaft 24 of the first module 211 and the second module 212. The present invention does not limit the specific form of the elastic member 23.

[0073] In summary, the housing assembly 100 provided by the embodiment of the present invention has the following beneficial effects:

[0074] The present invention is provided with a first module 211 and a second module 212 that can rotate relative to each other. When the plug-in component 20 is installed or removed, the optical fiber assembly 30 can move relative to the plug-in component 20, so that the optical fiber assembly 30 enters or moves out of the first through hole 214 from the gap between the first module 211 and the second module 212, so as to prevent the plug-in component 20 from colliding with the optical fiber and causing damage to the optical fiber when the plug-in component 20 is installed or removed. The plug-in component 20 can be installed by plugging, and there is no need to align the optical fiber position. It is easy to disassemble and convenient to clean the optical fiber coupling end. The present invention is easy to disassemble, convenient to clean the optical fiber, and avoids damage to the optical fiber during installation and disassembly. In addition, before fully inspecting the lens inside the housing assembly 100, it is necessary to use an air gun to blow the housing assembly 100 to blow away the dirt such as particles in the housing 10, which has a certain probability of causing the optical fiber receiving end to be dirty. By unplugging the plug-in component 20, the optical fiber can be cleaned in the next step, thereby reducing costs, manpower and material resources.

[0075] The embodiment of the present invention further provides a method for cleaning the end face of an optical fiber coupling end, which is applied to the above-mentioned housing assembly 100 and specifically includes the following steps:

[0076] S1, disassembling the plug-in component 20;

[0077] S2, cleaning the end face of the optical fiber coupling end;

[0078] S3. Install the plug-in component 20.

[0079] It can be understood that the optical fiber assembly 30 extends into the accommodating cavity 11 through the through hole 12. The optical fiber coupling end face is arranged at the end of the optical fiber assembly 30 extending into the accommodating cavity 11. The optical fiber assembly 30 includes a fiber core 31 and a ferrule 32 wrapping the fiber core 31. One end of the fiber core 31 is exposed from the ferrule 32. The end face of the end of the fiber core 31 exposed from the ferrule 32 is the optical fiber coupling end face.

[0080] Before performing the above step S1, the housing assembly 100 may be in a working state, that is, illuminating the optical fiber assembly 30 for optical coupling; the housing assembly 100 may also be in a standby state, and the above method of the present invention is not limited thereto, and it is only necessary to ensure that the optical fiber assembly 30 is inserted into the housing assembly 100.

[0081] Wherein, the above step S1 includes:

[0082] S1-1, moving the plug-in component 20 in the opposite direction of the plug-in direction of the plug-in component 20;

[0083] S1-2, separate the first module 211 and the second module 212, so that the first module 211 and the second module 212 move relative to the end surface of the optical fiber coupling end, and expose the end surface of the optical fiber coupling end.

[0084] Optionally, the above steps S1-1 and S1-2 can be performed simultaneously, that is, the first module 211 and the second module 212 are separated while the plug-in component 20 is moved. It is only necessary to ensure that the first module 211 and the second module 212 are separated before contacting the fiber core 31 of the optical fiber assembly 30.

[0085] The above step S2 comprises:

[0086] S2-1, moving the plug-in component 20 along the plug-in direction of the plug-in component 20;

[0087] S2-2, separating the first module 211 and the second module 212, so that the first module 211 and the second module 212 move relative to the end surface of the optical fiber coupling end, and moving the first through hole 214 to a position corresponding to the end surface of the optical fiber coupling end;

[0088] S2 - 3 , close the first module 211 and the second module 212 so that the fiber core 31 of the optical fiber assembly 30 is located in the first through hole 214 .

[0089] In summary, the method for cleaning the end face of the optical fiber coupling end provided in the embodiment of the present invention adopts a detachable split plug-in component 20, which can realize the rapid installation and disassembly of the plug-in component 20, conveniently expose the fiber core 31 of the optical fiber assembly 30, and inspect and clean the end of the fiber core 31 away from the plug core 32.

[0090] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
