Background of the Invention Optical fiber communications are suitable for use in a variety of applications including voice communications, data communications, and the like. In the existing light
纤到户的施工中，为了方便通信光纤的连接，大量使用通信光纤快速连接器， 将裸光纤***光纤快速连接器的光纤槽内书。在***光纤快速连接器前， 需要 将裸光纤的长度确定， 然后用切割工具进行切割， 这对光缆中的光纤切割长 度的精度要求很高， 而传统的做法是人为估计， 长度不够准确。 为解决上述裸光纤切割精度不够准确的问题， 现有中国专利文献 CN 202453554 U公开了一种皮线光缆的裸光纤定长工具， 包括基板， 基板上设 置有皮线通道和光纤通道， 皮线通道位于基板的前段， 光纤通道位于基板的 后段， 皮线通道和光纤通道处于直线上， 皮线通道的末端设置有挡面， 其优 点是将涂覆层剥离后的皮线光缆卡入基板的定位槽内， 挡面前部分为皮线部 分， 挡面后部分为光纤部分， 挡面至切割刀的距离为裸光纤的长度。 将装有 皮线光缆的该申请的结构放入切割工具的安装槽内， 切割后得到长度一致的 裸光纤， 操作比较方便。 然而，现有的光缆由于规格尺寸之间存在差异，如光缆的外径有 0.9mm， 1.6mm, 2.0mm以及 3.0mm等不同的种类， 在切割光纤时， 需要针对每一种 不同规格的光缆配置相应尺寸的光纤定长切割工具， 而上述申请中的定长工 具在光纤切割定长时， 可适用的光缆规格比较单一， 也无法在其基础上通过 更换配件来实现不同规格光缆的光纤定长， 更无法实现多种规格的光缆的通 用， 存在很大的局限性； 同时， 对不同规格的光缆进行切割时配置不同的定 长工具， 也会造成操作不便和资源的浪费。 发明内容 In the fiber-to-the-home construction, in order to facilitate the connection of the communication fiber, a large number of communication fiber quick connectors are used, and the bare fiber is inserted into the fiber slot of the fiber quick connector. Before inserting the fiber optic quick connector, the length of the bare fiber needs to be determined, and then cutting with a cutting tool, which requires high precision of the fiber cutting length in the cable, and the conventional method is artificially estimated, and the length is not accurate enough. In order to solve the problem that the above-mentioned bare fiber cutting precision is not accurate enough, the prior Chinese patent document CN 202453554 U discloses a bare fiber lengthening tool for a sheath optical cable, comprising a substrate on which a sheath channel and a fiber channel are provided, and a leather line The channel is located at the front of the substrate, the fiber channel is located at the rear of the substrate, the line channel and the fiber channel are in a straight line, and the end of the line channel is provided with a stop surface, which has the advantage of clamping the stripped optical cable into the substrate In the positioning groove, the front part of the block is the leather line part, the rear part of the block surface is the fiber part, and the distance from the stop surface to the cutting blade is the length of the bare fiber. The structure of the application with the sheathed cable is placed in the mounting slot of the cutting tool, and the bare fiber of the same length is obtained after cutting, which is convenient to operate. However, existing optical cables differ in size from specification to size, such as the outer diameters of optical cables of 0.9 mm, 1.6 mm, 2.0 mm, and 3.0 mm. When cutting optical fibers, it is necessary to use optical cables of different specifications. The fiber-length fixed-length cutting tool of the corresponding size is configured, and the fixed-length tool in the above application can be applied to the fiber-optic cable of different specifications by replacing the accessory when the fiber is cut and fixed length. Long, it is impossible to achieve the communication of various specifications of optical cable There are a lot of limitations; at the same time, different lengths of tools are required to cut different specifications of the cable, which will also cause inconvenience and waste of resources.

下面通过将该光纤定长工具放入切割工具 5中进行光纤定长的过程来进 一歩说明其具体结构。  The specific structure will be further described below by placing the fiber lengthening tool into the cutting tool 5 to perform the fiber lengthening process.
如图 5、 图 6所示， 在光纤切割定长时， 将该光纤定长工具放入切割工 具 5中， 使卡位 2的三组夹持部 211中的一组对齐光缆通道 12， 此时， 第二 孔 142上的三个定位槽 143分别与固定轴 22上的三个定位凸起 222配合固 定， 安装稳定后， 便可将与对齐光缆通道 12的夹持部 211的宽度相匹配的 光缆 3放入该夹持部 211中， 并通过夹持部 211的两侧面的夹紧凸起 212将 置入其中的光缆 3夹紧， 该光缆 3中的光纤 4沿着光纤通道 11放置， 并通 过光缆通道 12与光纤通道 11之间的挡面 13对光缆 3进行限位， 装配后， 挡面 13至切割工具 5的切割刀的距离即为光纤 3的长度，便可实现对光纤 3 的定长， 最终通过切割工具 5的切割刀切割光纤， 切割后的长度一致， 操作 比较方便。 而当需要切割定长另一种规格的光缆 3的光纤 4时， 仅需压紧卡 位 2的固定轴 22， 使固定轴 22在受到外力挤压作用时会发生变形， 当固定 轴 22发生变形后， 便可使卡位 2在基底 1的第二孔 142中轻松转动， 用于 实现不同宽度的夹持部 211之间的切换。 转动过程中， 当与要切割的光缆 3 的规格相匹配的夹持部 211与光缆通道 12对齐时， 慢慢放松对固定轴 22的 挤压， 使固定轴 22在自身的材料塑性特性的影响下恢复初始尺寸， 固定轴 22上的定位凸起 222再次对应地卡入定位槽 143中，将卡位 2固定在基底 1 上， 并完成不同档位之间的切换。 另外， 也可通过压紧卡位 2的固定轴 22， 使其在受到外力挤压作用发生变形时， 将卡位 2从基底 1 的卡位固定孔 14 中取出， 在基底 1的外部自由转动， 当转动到需要的档位与光缆通道 12可 对齐时， 压紧固定轴 22， 使其发生变形， 将卡位 2放入卡位固定孔 14中， 通过定位槽 143与定位凸起 222的配合将卡位 2固定，也可实现档位的切换。 该光纤定长工具通过多组夹持部 211实现不同规格的光缆的光纤定长切割， 多个档位之间切换操作简单， 还可避免因不同规格光缆而单独配备对应的光 纤定长工具造成的资源浪费， 有效节省资源。 As shown in FIG. 5 and FIG. 6, when the optical fiber is cut and fixed length, the optical fiber lengthening tool is placed in the cutting tool 5, and one of the three sets of clamping portions 211 of the card position 2 is aligned with the cable channel 12, The three positioning slots 143 of the second hole 142 are respectively fixed with the three positioning protrusions 222 on the fixed shaft 22, and after the installation is stabilized, the width of the clamping portion 211 of the alignment cable channel 12 can be matched. The optical cable 3 is placed in the clamping portion 211, and the optical cable 3 placed therein is clamped by the clamping protrusions 212 on both sides of the clamping portion 211, and the optical fiber 4 in the optical cable 3 is placed along the optical fiber channel 11. And limiting the optical cable 3 through the blocking surface 13 between the optical cable channel 12 and the optical fiber channel 11, after assembly, The distance between the stop surface 13 and the cutting blade of the cutting tool 5 is the length of the optical fiber 3, so that the fixed length of the optical fiber 3 can be realized. Finally, the optical fiber is cut by the cutting blade of the cutting tool 5, and the length after cutting is uniform, and the operation is convenient. When it is necessary to cut the optical fiber 4 of the optical cable 3 of another specification, only the fixed shaft 22 of the card 2 needs to be pressed, so that the fixed shaft 22 is deformed when pressed by an external force, when the fixed shaft 22 occurs. After the deformation, the card position 2 can be easily rotated in the second hole 142 of the substrate 1 for switching between the clamping portions 211 of different widths. During the rotation, when the clamping portion 211 matching the specification of the optical cable 3 to be cut is aligned with the cable passage 12, the pressing of the fixed shaft 22 is slowly relaxed, so that the influence of the fixed shaft 22 on its own plastic property is affected. The initial size is restored, and the positioning protrusion 222 on the fixed shaft 22 is again snapped into the positioning groove 143 to fix the card position 2 on the substrate 1, and the switching between different gear positions is completed. In addition, by pressing the fixed shaft 22 of the card slot 2, when the external force is pressed and deformed, the card slot 2 is taken out from the card fixing hole 14 of the base 1 and freely rotated outside the substrate 1. When the rotation to the required gear position is aligned with the cable channel 12, the fixed shaft 22 is pressed to deform, and the card position 2 is placed in the card fixing hole 14 through the positioning groove 143 and the positioning protrusion 222. In conjunction with the fixed position of the card 2, the gear position can also be switched. The fiber lengthening tool realizes the fixed length cutting of the optical fiber cables of different specifications through the plurality of sets of clamping portions 211, and the switching operation between the plurality of gear positions is simple, and the corresponding fiber length fixing tools are separately provided due to different specifications of the optical cables. Waste of resources and effectively save resources.
本发明的光纤定长工具的卡位 2上的夹持部 211的数量也可以为 2组、 4组或更多组， 相应的， 卡位 2与基底 1的固定方式也不仅限于此。 如当有 3组夹持部 211时， 不仅可用上述定位槽 143与定位凸起 222配合固定， 还 可以将固定轴 22设置成横截面为三角形或多边形的轴， 将第二孔 142设置 为与固定轴 22 的截面相匹配的三角形或多边形， 通过面与面之间的配合、 以及三角形或多边形本身的内角的卡合， 同样可以稳定固定卡位 2; 当然， 卡位 2的固定轴 22与第二孔 142之间也可以设置为紧配合， 通过转动实现 档位之间的切换。 The number of the clamping portions 211 on the card slot 2 of the optical fiber fixing tool of the present invention may also be two groups, four groups or more. Accordingly, the manner of fixing the card slot 2 and the substrate 1 is not limited thereto. For example, when there are three sets of clamping portions 211, not only the positioning grooves 143 can be fixed and fixed with the positioning protrusions 222, but also the fixed shaft 22 can be arranged as a triangular or polygonal axis, and the second holes 142 can be set to The triangle or polygon matching the cross section of the fixed shaft 22 can also stably fix the card slot 2 by the fit between the face and the face, and the inner corner of the triangle or the polygon itself; The fixed shaft 22 of the card position 2 and the second hole 142 can also be arranged to be tightly engaged, and the switching between the gear positions is realized by the rotation.
