Description

Technical Field

[0001] This invention belongs to the technical field of fiber optic lamps, specifically relating to a fiber optic assembly, a light guide fiber braid, and a processing technology for the fiber optic assembly. Background Technology

[0002] After optical fibers are bundled together, they can be used to transmit light sources. Compared with traditional light source transmission, this method of light source transmission has the characteristics of high purity, low attenuation, convenient installation, reliability, safety, environmental protection, flexibility and integrity, and therefore it has been widely used.

[0003] Current technology typically uses tape wrapped around the outer surface of the fiber bundle to prevent it from scattering. However, this method is not suitable for mass production, and due to varying operator techniques, defective products are easily produced if the wrapping is done for an extended period. Therefore, there is significant room for improvement. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the prior art by proposing an optical fiber assembly.

[0005] The objective of this invention can be achieved through the following technical solution: an optical fiber assembly, comprising:

[0006] Several optical fiber units, each optical fiber unit including the light-inlet end;

[0007] A sheath is fitted over the light-inlet end of each optical fiber unit and bundles the light-inlet ends of each optical fiber unit to form an optical fiber bundle, wherein the end face of the optical fiber bundle is a plane.

[0008] A fixing component is fitted over the sheath and fixedly connected to the sheath. The fixing component also includes a connecting part fixedly connected to the light source module. The light from the light source module can be dispersed into each fiber optic unit through the end face of the fiber bundle.

[0009] Preferably, the sheath is a heat shrink tubing sheath.

[0010] Preferably, the inner wall of the fastener is configured as a first adhesive surface, and the outer peripheral surface of the sheath is configured as a second adhesive surface, wherein the first adhesive surface and the second adhesive surface are bonded together with adhesive.

[0011] Preferably, the fixing member includes a bundle head bracket and a fastener. The fastener is sleeved on the sheath and has a deformable snap-fit ​​end. The snap-fit ​​end is provided with a plurality of opening slots that allow the snap-fit ​​end to deform. The bundle head bracket is sleeved on the fastener, and the bundle head bracket allows the snap-fit ​​end to deform toward the sheath, thereby causing the fastener to hold the optical fiber bundle tightly.

[0012] Preferably, the outer peripheral surface of the snap-fit ​​end is provided with a rib, and the inner wall of the head bracket abuts against the rib, thereby causing the snap-fit ​​end to deform toward the sheath.

[0013] Preferably, the peripheral surface of the fixing member is provided with a deformable clamping part, and an external force is applied to the clamping part to deform it toward the sheath, thereby clamping the optical fiber bundle.

[0014] Secondly, a light-guiding fiber braid is also provided, comprising warp and weft yarns interwoven together, wherein one or both of the warp and weft yarns are light-guiding fibers, and the light-guiding fibers belonging to the same warp or weft yarn are aggregated to form at least one of the above-mentioned optical fiber components.

[0015] Secondly, a processing technology for optical fiber components is also provided, including the following steps:

[0016] S1: Several optical fiber units are bundled together, and then a sheath is placed over the light-inlet end of the bundled optical fiber units. The sheath is then heated to shrink it and tightly wrap the light-inlet end of the bundled optical fiber units to form an optical fiber bundle.

[0017] S2: Fit the fastener onto the outside of the sheath and secure the fastener to the sheath.

[0018] S3: Grind and polish the end face of the optical fiber bundle to form a flat surface.

[0019] Preferably, in step S2, adhesive is first applied to the first adhesive surface of the fastener or the second adhesive surface of the sheath, and then the first adhesive surface and the second adhesive surface are brought into contact and connected to secure the fastener and the sheath together.

[0020] Preferably, in step S2, the fixing member is configured as a head bracket and a buckle. First, the buckle is put on the sheath, and then the head bracket is put on the buckle. The inner wall of the head bracket can cause the snap-fit ​​end of the buckle to deform towards the sheath, thereby fastening the buckle and the sheath together.

[0021] Preferably, in step S2, the fixing member is provided with a clamping part, and an external force is applied to the clamping part to deform it toward the sheath, thereby clamping the optical fiber bundle. The clamping part clamps the optical fiber bundle, thereby fastening the fixing member and the sheath together.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. The light-gathering ends of each fiber unit in the fiber optic assembly are brought together by a sheath and a fixing component to form a fiber bundle head, preventing any loosening. The fixing component also has a connection part that is fixedly connected to the light source module, allowing the fiber optic assembly to be easily assembled or disassembled with the light source module. The light from the light source module can be dispersed into each fiber unit through the end face of the fiber bundle.

[0024] 2. The fiber optic cable holder deforms to hold the fiber optic bundle tightly. This fiber optic assembly is detachable and more convenient to use.

[0025] 3. It is equipped with an opening groove, and the tightness can be adjusted by the width and axial length of the opening groove, which is a very ingenious structure.

[0026] 4. The inner wall of the snap-fit ​​end or bundle head bracket is provided with ribs. In actual assembly, the bundle head bracket only needs to be fitted onto the snap-fit ​​part to deform the snap-fit ​​end of the snap-fit ​​part towards the sheath, thereby making the snap-fit ​​part hold the fiber bundle tightly. No other operation is required, and the assembly is very convenient. Attached Figure Description

Detailed Implementation

[0037] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0038] Example 1

[0039] like Figures 1-3 As shown, an optical fiber assembly includes: a plurality of optical fiber units 110, a fixing member 200, and a sheath 300. Each optical fiber unit includes a light-inlet end. The light-inlet ends of the plurality of optical fiber units 110 are bundled together to form an optical fiber bundle 100, the end face of which is planar. The sheath 300 is fitted over the optical fiber bundle 100 to constrain and protect it. The fixing member 200 is fitted over the sheath 300 for fastening to the sheath 300. The fixing member 200 also has a connection portion for fixed connection to a light source module. Light from the light source module can be dispersed into each optical fiber unit 110 through the end face of the optical fiber bundle 100. The planar end face of the optical fiber bundle 100 allows for more uniform light distribution among the optical fiber units 110.

[0040] Specifically, the sheath 300 uses a heat shrink tubing sheath. In actual use, the sheath 300 only needs to be heated, and the sheath 300 can shrink to firmly hold the fiber bundle 100, thus preventing the fiber bundle 100 from dispersing.

[0041] In addition, the sheath 300 also serves a protective function. In order for the fastener 200 and the fiber bundle 100 to be combined into one unit, the fastener 200 inevitably needs to be connected to the fiber bundle 100 in contact. If the fastener 200 is directly connected to the fiber bundle 100 in contact, the fiber bundle 100 may be damaged when the fastener 200 and the fiber bundle 100 are assembled too tightly. Therefore, when the fastener 200 is connected to the fiber bundle 100 through the sheath 300, the fiber bundle 100 will not be damaged. The sheath 300 can play a buffering role, thus protecting the fiber bundle 100 well.

[0042] In this embodiment, the fastener 200 is actually a hollow tubular structure. The inner wall of the fastener 200 is set as the first adhesive surface 210, and the outer peripheral surface of the sheath 300 is set as the second adhesive surface 310. The first adhesive surface 210 or the second adhesive surface 310 can be coated with glue. Therefore, the first adhesive surface 210 and the second adhesive surface 310 can be bonded together with glue, thereby connecting the fastener 200 and the sheath 300 together.

[0043] In this embodiment, the optical fiber assembly can be applied to a light guide fiber braid. This type of light guide fiber braid is woven from optical fiber units 110. The fixing part 200 of the optical fiber assembly is connected to the light source module. The light from the light source module can be dispersed into each optical fiber unit 110 through the end face of the optical fiber bundle 100. Then the light is emitted from the side of each optical fiber unit 110, forming the effect of the entire braid emitting light.

[0044] Secondly, a light guide fiber braid is also provided, which includes warp and weft yarns woven together, one or both of which are light guide fibers, and the light guide fibers belonging to the same warp or weft yarn are aggregated into at least one optical fiber assembly as described above.

[0045] Secondly, the processing technology for optical fiber components is also provided, and the specific steps are as follows:

[0046] S1: Several fiber optic units 110 are bundled together, and then a sheath 300 is placed on the light-inlet end of the bundled fiber optic units 110. Then the sheath 300 is heated to shrink the sheath 300 and tightly wrap the light-inlet end of the bundled fiber optic units to form a fiber optic bundle 100.

[0047] S2: Fit the fastener 200 onto the outer sleeve 300 and secure the fastener 200 to the sleeve 300.

[0048] S3: Grind and polish the end face of the fiber bundle 100 to form a flat surface.

[0049] It should be noted that in step S2, glue is first applied to the first adhesive surface 210 of the fastener 200 or the second adhesive surface 310 of the sheath 300, and then the first adhesive surface 210 and the second adhesive surface 310 are brought into contact and connected to secure the fastener 200 and the sheath 300 together.

[0050] Example 2

[0051] The difference between Embodiment 2 and Embodiment 1 is that the fixing member 200 is not fixed to the fiber bundle 100 by glue, such as... Figures 4-6As shown, the fixing component 200 includes a bundle head bracket 220 and a fastener 230. The bundle head bracket 220 and the fastener 230 work together to bring the fiber bundle 100 together.

[0052] Specifically, the fastener 230 is fitted onto the sheath 300, and the bundle head bracket 220 is fitted onto the fastener 230. The fastener 230 has a deformable snap-fit ​​end 231. The bundle head bracket 220 can be configured as a hollow tubular structure. When the bundle head bracket 220 is fitted onto the fastener 230, the inner wall of the bundle head bracket 220 abuts against the snap-fit ​​end 231, causing the snap-fit ​​end 231 to deform toward the sheath 300, thereby causing the fastener 230 to hold the fiber bundle 100 tightly. In this way, the fiber bundle 100, the fastener 230, and the bundle head bracket 220 are combined to form an integrated fiber optic assembly.

[0053] It should be noted that the fiber optic assembly 220 allows the connector 231 to deform and hold the fiber optic bundle 100 tightly. This fiber optic assembly is detachable and more convenient to use in practice.

[0054] Preferably, the peripheral surface of the snap-fit ​​end 231 is provided with a plurality of opening slots 232. The opening slots 232 are used to deform the snap-fit ​​end 231. In the actual structure, the width and axial length of the opening slots 232 can be set according to the tightness of the snap fastener 230 on the optical fiber assembly.

[0055] It should be noted that an opening groove 232 is provided, and the tightness can be adjusted by the width and axial length of the opening groove 232, making the structure very practical.

[0056] Preferably, the snap-fit ​​end 231 has a raised rib 233 around its circumference. The raised rib 233 effectively increases the outer diameter of the snap-fit ​​end 231. Thus, when the head bracket 220 is fitted onto the fastener 230, the inner wall between the head brackets can abut against the raised rib 233 of the snap-fit ​​end 231, easily causing deformation of the snap-fit ​​end 231 towards the sheath 300. Alternatively, the raised rib 233 can be placed on the inner wall of the head bracket 220. This effectively reduces the inner diameter of the head bracket 220. When the head bracket 220 is fitted onto the fastener 230, the raised rib 233 on the inner wall of the head bracket 220 abuts against the snap-fit ​​end 231, causing deformation of the snap-fit ​​end 231.

[0057] It should be noted that the outer peripheral surface of the snap-fit ​​end 231 or the inner wall of the bundle head bracket 220 is provided with a protruding rib 233. In actual assembly, the bundle head bracket 220 only needs to be fitted onto the snap-fit ​​part 230 to deform the snap-fit ​​end 231 of the snap-fit ​​part 230 toward the sheath 300, thereby making the snap-fit ​​part 230 hold the fiber bundle 100 tightly. No other operation is required, and the assembly is very convenient.

[0058] Secondly, the processing technology of the fiber bundle 100 head in Embodiment 2 is different from that in Embodiment 1 in step S2. In step S2 of Embodiment 2, the fixing member 200 is set as a bundle head bracket 220 and a buckle member 230. First, the buckle member 230 is put on the sheath 300, and then the bundle head bracket 220 is put on the buckle member 230. The inner wall of the bundle head bracket 220 can cause the snap-fit ​​end 231 of the buckle member 230 to deform towards the sheath 300, thereby fastening the buckle member 230 and the sheath 300 together.

[0059] Example 3

[0060] The difference between Embodiment 3 and Embodiments 2 and 1 lies in the connection method between the fixing member 200 and the optical fiber bundle 100, such as... Figures 7-9 As shown, the fixing member 200 is provided with a deformable clamping part 240. The optical fiber bundle 100 is clamped by the deformation of the clamping part 240, so that the fixing member 200 and the optical fiber bundle 100 are combined to form an integrated optical fiber assembly.

[0061] Specifically, the clamping part 240 is disposed on the outer peripheral surface of the fixing member 200. In order to make the clamping part 240 more easily deformable, the thickness of the clamping part 240 is much smaller than the thickness of other parts of the fixing member 200. In this way, when the fixing member 200 is fitted onto the sheath 300 outside the fiber bundle 100, only a certain external force needs to be applied to the clamping part 240 to deform in the direction of the fiber bundle 100, thereby clamping the fiber bundle 100. Through this connection method, the fixing member 200 and the fiber bundle 100 are combined to form an integrated fiber optic assembly.

[0062] Secondly, step S2 of the processing technology of the fiber bundle 100 head in Embodiment 3 is different from that in Embodiment 1 and Embodiment 2. In step S2 of Embodiment 3, the fixing member 200 is provided with a clamping part 240. An external force is applied to the clamping part 240 to deform it toward the sheath 300, thereby clamping the fiber bundle 100. The clamping part 240 clamps the fiber bundle 100, thereby fastening the fixing member 200 and the sheath 300 together.

[0063] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0064] Furthermore, in this invention, descriptions involving terms such as "first," "second," and "a" are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0065] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0066] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.
