[0005] In a first aspect, the embodiments of the present application provide an optical fiber assembly, which comprises an optical fiber, a ferrule tail handle and a limiting piece.

DETAILED DESCRIPTION

[0031] In order for those skilled in the art to better understand the scheme of the application, the technical scheme in the embodiments of the application will be clearly and completely described below in combination with the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, but not all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without making creative efforts fall within the scope of the application.

[0032] The technical solutions in the embodiments will be clearly and completely described in connection with the drawings in the embodiments of the application.

[0033] In the related art, the optical fiber assembly includes an optical fiber, a threaded protection tube, a ferrule tail handle and a connecting support, the threaded protection tube can be sleeved on the outer periphery of the bare optical fiber of the optical fiber, the ferrule tail handle can be connected between the threaded protection tube and the connecting support, and the ferrule tail handle and the connecting support can jointly limit the ferrule. Since the outer diameter of the ferrule is larger than the inner hole of the ferrule tail handle, the ferrule cannot pass through the ferrule tail handle. Before assembly, the bare optical fiber of the optical fiber must be cut off, and the ferrule tail handle is sleeved on the outer periphery of the ferrule from one end of the bare optical fiber of the optical fiber, and the ferrule can be limited after the ferrule tail handle is threadedly connected with the connecting support. The capillary stainless steel tube and the fine threaded protection tube are respectively sleeved on the broken fiber, and after the broken part is re-fused, the capillary stainless steel tube and the threaded protection tube are moved to the fusion of the bare optical fiber, and each tube is fixed by the point gluing process, and finally the threaded protection tube is assembled. In this way, the entire assembly process is relatively complicated, and the fusion of the bare optical fiber and the multiple point gluing between the tubes limit the production efficiency and are prone to produce defective products. In addition, since the ferrule tail handle cannot be taken out of the optical fiber after assembly, if disassembly is required, the bare optical fiber must be continuously cut off, so that the optical fiber is almost impossible to reuse.

[0034] Please refer to Figures 1 to 3 The application provides a lamp 10, the lamp 10 can have a lighting function, and the lamp 10 can be used for a vehicle. The lamp 10 can include an optical fiber assembly 20 and a lens 30, and the lens 30 can focus, collimate or diffuse the light emitted by the optical fiber assembly 20.

[0035] In some embodiments, the lamp 10 can further include a light source, the light source can emit light, and the light emitted by the light source can be transmitted through the optical fiber assembly 20 so that the lens 30 can process the light emitted by the light source. The number of optical fiber assemblies 20 can be multiple, for example, two, three or four, and the specific number of optical fiber assemblies 20 can be designed according to the distance from the light source to the lens 30.

[0036] Please refer to Figure 2 and Figure 3 In some embodiments, the lamp 10 can include a fixing support 600, and the fixing support 600 can be connected to the optical fiber assembly 20. The fixing support 600 can be fixed to the vehicle, thereby helping to fix the optical fiber assembly 20 and helping the light passing through the lens 30 to be stably emitted. When the number of optical fiber assemblies 20 is multiple, two adjacent optical fiber assemblies 20 can be fixedly connected through the fixing support 600, so that the two adjacent optical fiber assemblies 20 can stably transmit light.

[0037] In some embodiments, the lamp 10 can further include a heat sink 700, which can be a heat dissipation fin, the heat sink 700 can be in thermal conduction connection with the fixing support 600, so as to help the heat sink 700 dissipate the heat transferred by the optical fiber assembly 20 to the fixing support 600.

[0038] Referring to Figures 2 to 4 The embodiments of the present application also provide an optical fiber assembly 20, which can be applied to the lamp 10 or an endoscope.

[0039] The optical fiber assembly 20 can include an optical fiber 100, a ferrule tail handle 220 and a limiting piece 300, the optical fiber 100 can include a bare optical fiber 110 and a ferrule 120 connected with each other, the ferrule tail handle 220 can have a through hole 223 Figure 6 shown in the figure, the through hole 223 can pass through the ferrule tail handle 220 along the axial direction of the ferrule tail handle 220, the ferrule 120 is detachably arranged in the through hole 223, and the limiting piece 300 is detachably connected with the optical fiber 100 and locks the ferrule 120 in the ferrule tail handle 220 along the axial direction of the ferrule tail handle 220. In this way, compared with the optical fiber assembly in the related art, the ferrule 120 of the optical fiber assembly 20 of the present application is detachably arranged in the through hole 223, so that the optical fiber assembly 20 can be assembled without breaking the bare optical fiber 110 of the optical fiber 100, thereby reducing the fiber breaking and re-melting process in the related art, and simplifying the assembly process, so that the assembly process of the optical fiber assembly 20 is relatively simple.

[0040] In addition, the limiting piece 300 can limit the ferrule 120 in the ferrule tail handle 220, so as to help limit the movement of the ferrule 120 relative to the ferrule tail handle 220, thereby reducing the risk of loosening of the ferrule 120 relative to the ferrule tail handle 220 during the assembly of the optical fiber assembly 20.

[0041] Moreover, since the optical fiber assembly 20 does not need to be broken and welded during assembly, the optical fiber 100 can be reused. At the same time, since the plurality of components of the optical fiber assembly 20 are detachable, when a certain component of the optical fiber assembly 20 is damaged or aged, it can be conveniently replaced without replacing the entire optical fiber assembly 20, thereby helping to reduce maintenance costs and reducing waste caused by replacing the entire optical fiber assembly 20.

[0042] Referring to Figure 4 and Figure 5In some embodiments, the optical fiber 100 can conduct a light beam for illumination, projection, etc., and can also load a communication signal in the light beam to realize optical communication. Both ends of the bare optical fiber 110 can be provided with a ferrule 120, which can be a ceramic ferrule 120, thereby facilitating the input of the light beam from the ferrule 120 at one end of the bare optical fiber 110 and the output of the light beam from the ferrule 120 at the other end of the bare optical fiber 110. In the following embodiments, the cooperation of the ferrule 120 at one end of the bare optical fiber 110 with the ferrule tail handle 220 and the limiting piece 300 is mainly introduced. The ferrule 120 at the other end of the bare optical fiber 110 can also cooperate with the ferrule tail handle 220 and the limiting piece 300, which is not limited here and can be specifically referred to the implementation.

[0043] In some embodiments, the limiting piece 300 is detachably sleeved on the bare optical fiber 110 or the ferrule 120 and at least partially limits the ferrule 120 in the through hole 223. The limiting piece 300 is detachably sleeved on the outer periphery of the bare optical fiber 110 or the ferrule 120, and the limiting piece 300 can be fixedly installed in the through hole 223 of the ferrule 120, for example, the limiting piece 300 can be relatively fixed with the ferrule tail handle 220 through the friction force between the outer wall of the limiting piece 300 and the inner wall of the through hole 223 (the limiting piece 300 can be embedded in the through hole 223 of the ferrule 120) or the buckle structure. In this way, it is helpful to realize that the limiting piece 300 at least partially limits the ferrule 120 in the through hole 223, thereby facilitating the ferrule 120 to be limited in the through hole 223 by the limiting piece 300 of the optical fiber assembly 20, and further helping to reduce the risk of movement or falling of the ferrule 120 relative to the ferrule tail handle 220 during use, so as to improve the stability and reliability of the optical fiber assembly 20.

[0044] In the present embodiment, the limiting piece 300 is detachably sleeved on the bare optical fiber 110 and abuts between the ferrule tail handle 220 and the ferrule 120 along the axial direction of the ferrule tail handle 220. Specifically, the outer diameter of the limiting piece 300 is slightly larger than the inner diameter of the through hole 223, the limiting piece 300 can be interference fit with the through hole 223 of the ferrule tail handle 220, and the limiting piece 300 abuts between the ferrule tail handle 220 and the ferrule 120 along the axial direction of the ferrule tail handle 220, thereby helping to reduce the risk of movement along the axial direction of the ferrule tail handle 220.

[0045] In addition, the optical fiber assembly 20 fills the gap between the ferrule tail handle 220 and the ferrule 120 along the axial direction of the ferrule tail handle 220 through the limiting piece 300, which is more helpful to reduce the risk of loosening or displacement of the ferrule 120 during use, thereby more helping to enhance the stability and reliability of the optical fiber assembly 20.

[0046] Please refer to Figures 4 to 6In some embodiments, the ferrule tail 220 can be provided with a stop portion 224 located at the through hole 223, the stop portion 224 can be provided with a connecting passage 224a communicated with the through hole 223, the connecting passage 224a can penetrate the stop portion 224 along the axial direction of the ferrule tail 220, and the limiting member 300 abuts between the stop portion 224 and the ferrule 120. Specifically, the stop portion 224 can be arranged along the circumferential direction of the inner wall of the ferrule tail 220, the hole diameter of the through hole 223 is greater than the hole diameter of the connecting passage 224a, the hole diameter of the connecting passage 224a is greater than the outer diameter of the ferrule 120, the outer diameter of the limiting member 300 is greater than the hole diameter of the connecting passage 224a, and the outer diameter of the limiting member 300 is less than the hole diameter of the through hole 223, so that the ferrule 120 can be arranged in the through hole 223, and the limiting member 300 can abut between the stop portion 224 and the ferrule 120. In addition, the stop portion 224 has a stop effect, so that the limiting member 300 can be accurately positioned at a predetermined position, which helps the operator to quickly install the limiting member 300 and the ferrule 120 at the predetermined position.

[0047] Referring to Figure 7 The overall shape of the limiting member 300 can be arranged in a U shape, and the limiting member 300 can be made of stainless steel. The limiting member 300 can be a limiting sheet, so that the overall structure of the optical fiber assembly 20 is more compact, and the volume of the optical fiber assembly 20 is smaller.

[0048] In some embodiments, the limiting member 300 can be provided with a clamping groove 310, and the bare optical fiber 110 can be clamped in the clamping groove 310, which helps the operator to quickly and conveniently sleeve the limiting member 300 on the bare optical fiber 110. The clamping groove 310 of the limiting member 300 can make the assembly of the bare optical fiber 110 simpler and more convenient. The operator only needs to clamp the bare optical fiber 110 into the clamping groove 310 to complete the assembly, without the need for complex tools or steps. When the optical fiber 100 needs to be disassembled or replaced, the operator only needs to take out the bare optical fiber 110 from the clamping groove 310 to complete the disassembly, and the operation process is more convenient.

[0049] In addition, since the limiting member 300 is provided with the clamping groove 310, the limiting member 300 can be sleeved on the outer periphery of the bare optical fiber 110, so that the limiting member 300 is easy to assemble on the bare optical fiber 110, and also makes the limiting member 300 flexible to be taken out during disassembly, thereby helping the ferrule 120 to be arranged in the ferrule tail 220 flexibly.

[0050] Referring to Figure 4In some embodiments, the optical fiber assembly 20 can further include a protective sleeve 210, which can be a threaded protective sleeve. The protective sleeve 210 can be sleeved on the outer periphery of the bare optical fiber 110, so as to protect the bare optical fiber 110 and prolong the service life of the bare optical fiber 110, thereby facilitating the normal operation of the optical fiber assembly 20.

[0051] The ferrule tail 220 is detachably connected to the protective sleeve 210. For example, the ferrule tail 220 can be connected to the protective sleeve 210 by means of threaded connection, snap connection or plug-in connection, so as to facilitate the detachable connection of the ferrule tail 220 to the protective sleeve 210. When the ferrule tail 220 or the protective sleeve 210 in the optical fiber assembly 20 is damaged, the ferrule tail 220 or the protective sleeve 210 can be conveniently disassembled for replacement or repair, without the need to replace the ferrule tail 220 and the protective sleeve 210 at the same time, which not only reduces the maintenance cost, but also reduces the waste of resources.

[0052] In some embodiments, the ferrule tail 220 can be sleeved on the outer periphery of the end portion of the protective sleeve 210, that is, the ferrule tail 220 can be sleeved on the outer periphery of the end portion of the protective sleeve 210 connected with the ferrule tail 220. Specifically, the connection between two adjacent parts is prone to breakage. By sleeving the ferrule tail 220 on the outer periphery of the end portion of the protective sleeve 210, the ferrule tail 220 and the protective sleeve 210 are partially overlapped at the connection, so as to enhance the connection strength of the ferrule tail 220 and the protective sleeve 210 at the connection, thereby making the entire optical fiber assembly 20 more stable. Of course, the connection between the ferrule tail 220 and the protective sleeve 210 can also be glued by means of a gluing process, so as to enhance the connection strength of the ferrule tail 220 and the protective sleeve 210, thereby further facilitating the stability and firmness of the connection between the ferrule tail 220 and the protective sleeve 210.

[0053] In addition, since the ferrule tail 220 can be sleeved on the outer periphery of the end portion of the protective sleeve 210, the risk of loosening or breakage of the connection between the ferrule tail 220 and the protective sleeve 210 due to external force or vibration during use is reduced, and the structure is relatively simple and the operation is relatively convenient.

[0054] In some embodiments, the difference between the inner diameter of the ferrule tail 220 and the outer diameter of the protective sleeve 210 is 5mm-15mm. That is, the difference between the inner diameter of the ferrule tail 220 and the outer diameter of the protective sleeve 210 located in the ferrule tail 220 is 5mm-15mm. Wherein, the difference between the inner diameter of the ferrule tail 220 and the outer diameter of the protective sleeve 210 located in the ferrule tail 220 can be, but is not limited to, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm or 15mm, etc. In this way, the difference between the inner diameter of the ferrule tail 220 and the outer diameter of the protective sleeve 210 located in the ferrule tail 220 is within the above range, so that the ferrule tail 220 can be smoothly and stably sleeved on the end of the protective sleeve 210, and a certain gap is formed between the ferrule tail 220 and the protective sleeve 210, which helps to reserve space between the ferrule tail 220 and the end of the protective sleeve 210 to form an adhesive layer, wherein the adhesive layer can be formed by a dispensing process.

[0055] In addition, since a gap can be formed between the ferrule tail 220 and the end of the protective sleeve 210, it helps to reduce the risk of large wear of the ferrule tail 220 and the end of the protective sleeve 210 during assembly, thereby helping to prolong the service life of the ferrule tail 220 and the protective sleeve 210.

[0056] In some embodiments, the optical fiber assembly 20 can further include a connecting bracket 400, the ferrule tail 220 is detachably connected to the connecting bracket 400, and the end of the ferrule 120 away from the limiting piece 300 abuts the connecting bracket 400 along the axial direction of the ferrule tail 220, thereby helping the connecting bracket 400 to limit the movement of the ferrule 120 in the direction away from the limiting piece 300.

[0057] Wherein, for example, the ferrule tail 220 can be connected with the connecting bracket 400 through threaded connection, buckle connection or plug-in connection, etc., thereby helping the ferrule tail 220 to be detachably connected to the connecting bracket 400. When the ferrule tail 220 or the connecting bracket 400 of the optical fiber assembly 20 is damaged, the ferrule tail 220 or the connecting bracket 400 can be conveniently disassembled for replacement or maintenance, without the need to replace the ferrule tail 220 or the connecting bracket 400 at the same time, which not only reduces the maintenance cost, but also reduces the waste of resources.

[0058] In some embodiments, the connecting bracket 400 can also be connected to the fixing bracket 600, for example, the connecting bracket 400 can be connected to the fixing bracket 600 by snap connection or threaded connection, etc. Since the ferrule 120 is limited and fixed to the ferrule tail handle 220, and the connecting bracket 400 is connected to the fixing bracket 600, thereby helping the optical fiber assembly 20 to be fixed to the place to be applied by the fixing bracket 600, for example, the optical fiber assembly 20 can be fixed to the vehicle by the fixing bracket 600, so that the whole optical fiber 100 is not easy to move during work, thereby making the overall structure of the optical fiber assembly 20 stable, and further helping the optical fiber assembly 20 to stably transmit light beams.

[0059] In some embodiments, the limiting piece 300 and the connecting bracket 400 can jointly enclose a limiting space, and the ferrule 120 is located in the limiting space. Specifically, the aperture size of the limiting space can be matched with the size of the ferrule 120, which helps the limiting space to limit the ferrule 120, thereby helping to reduce the risk of the ferrule 120 moving in the limiting space, and further helping to limit the axial and radial movement of the ferrule 120 along the ferrule tail handle 220.

[0060] The limiting space can extend through the connecting bracket 400 along the length direction, and the connecting bracket 400 can also be provided with a mounting hole and a light passing hole, both of which can be communicated with the limiting space. The mounting hole and the light passing hole can be located at two ends of the connecting bracket 400 respectively. The mounting hole can be located at one end of the connecting bracket 400 facing the limiting piece 300, and the light passing hole can be located at one end of the connecting bracket 400 away from the limiting piece 300. The aperture of the mounting hole can be larger than the outer diameter of the ferrule 120, thereby helping the ferrule 120 to be installed in the limiting space. The aperture of the light passing hole can be smaller than the outer diameter of the ferrule 120, which helps the light emitted from the ferrule 120 to be emitted from the light passing hole.

[0061] In some embodiments, the connecting bracket 400 can have a connecting portion 410, the ferrule tail 220 is detachably connected to the connecting portion 410, the end of the ferrule 120 away from the limiting member 300 abuts the connecting portion 410 along the axial direction of the ferrule tail 220, and the distance between the end of the protective sleeve 210 and the stop portion 224 is greater than the length of the connecting portion 410. In this way, during the disassembly of the optical fiber assembly 20, since the ferrule tail 220 is detachably connected to the protective sleeve 210 and the ferrule tail 220 is detachably connected to the connecting bracket 400, the ferrule tail 220 can be detached relative to the protective sleeve 210 and the connecting bracket 400, and the distance between the end of the protective sleeve 210 and the stop portion 224 is greater than the length of the connecting portion 410, the additional space can be provided in the through hole 223, the disassembly stroke of the ferrule tail 220 is reserved, the protective sleeve 210 can be more easily detached from the connecting bracket 400 during the movement of the ferrule tail 220 towards the protective sleeve 210, and the ferrule tail 220 can be more easily detached from the protective sleeve 210 during the movement of the ferrule tail 220 towards the connecting bracket 400, thereby helping to reduce the pulling of the protective sleeve 210 (the length of the protective sleeve 210 is relatively long, and it is difficult to move the entire protective sleeve 210 during disassembly).

[0062] Based on the above embodiment, the installation process of the optical fiber assembly 20 is as follows:

[0063] Step one: please refer to Figure 8 The ferrule 120 is arranged in the protective sleeve 210, so that the bare optical fiber 110 is located in the protective sleeve 210 and the ferrule 120 is located outside the protective sleeve 210.

[0064] Step two: please refer to Figure 9 The ferrule tail 220 is sleeved on the outer periphery of the end of the protective sleeve 210, and the ferrule 120 is arranged in the ferrule tail 220.

[0065] Step three: please refer to Figure 10 The limiting member 300 is sleeved on the outer periphery of the bare optical fiber 110, and the limiting member 300 abuts between the stop portion 224 and the ferrule 120.

[0066] Step four: move the ferrule tail 220 towards the connecting bracket 400, and threadedly connect the ferrule tail 220 with the connecting bracket 400.

[0067] Step five: reinforce the connection between the ferrule tail 220 and the protective sleeve 210 by the glue dispensing process, so that the assembly of the entire optical fiber assembly 20 is completed.

[0068] Based on the above embodiment, the disassembly process of the optical fiber assembly 20 is as follows:

[0069] Step one: use the debonding agent to clean the glue at the joint between the ferrule tail 220 and the protective sleeve 210.

[0070] Step two: twist the ferrule tail 220 relative to the connecting bracket 400, so that the ferrule tail 220 is separated from the connecting bracket 400.

[0071] Step three: move the ferrule tail 220 towards the protective sleeve 210, so that the limiting member 300 is exposed outside the ferrule tail 220, and the limiting member 300 is taken out.
