Description

Technical Field

[0001] This utility model belongs to the technical field of optical fiber straightening, and specifically relates to a ruler tool for adjusting the bending curvature of optical fibers. Background Technology

[0002] Devices using fiber optic communication require fiber optic cables to connect to their fiber optic communication interfaces. When using fiber optic cables to connect devices, there is usually some slack in length. To reduce the risk of damage caused by excess cable tangling, the fiber optic cables need to be neatly arranged and secured.

[0003] Currently, in the field of electrical engineering, when using fiber optic cable connection equipment and organizing the connected fiber optic cables in the field, the operator's experience is generally relied upon to control the bending curvature of the fiber optic cables, and the cables are secured with cable ties or straps. If the bending curvature is too small, the optical fibers inside the cable may break, damaging the cable; if the curvature is too large, the fiber optic cable may naturally bend and become tangled. Utility Model Content

[0004] This invention provides a ruler tool for adjusting the bending curvature of optical fibers, thereby solving the problem of difficulty in controlling the bending curvature of optical fiber cables.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A ruler tool for adjusting the bending curvature of an optical fiber includes a flexible support strip, the support strip including a first sidewall and a second sidewall disposed opposite to each other;

[0007] The support strip includes several basic segments, each of which is provided with an installation space for placing optical fiber cables, and each of the basic segments includes an installation groove formed on the first side wall of the support strip and an installation protrusion protruding from the second side of the support strip.

[0008] When the support strip is bent, the mounting protrusion at one end of the support strip can be engaged with the corresponding mounting groove at the other end.

[0009] Furthermore, the basic segment includes a first clip and a second clip symmetrically fixed to a set of opposite sidewalls of the support strip. Both the first clip and the second clip include a widening section and a limiting section. The widening section is on the same plane as the support strip, and the limiting section is bent relative to the widening section. The area enclosed by the first clip and the second clip forms an installation space.

[0010] Furthermore, the limiting segment bends toward the side of the support strip where the mounting groove is formed.

[0011] Furthermore, the basic segment is provided with mounting protrusions, mounting grooves and mounting spaces in sequence from one side to the other.

[0012] Furthermore, the support strip has a scale marking on the side wall that fixes the first or second clip to indicate the diameter of the circle formed by the support strip after bending.

[0013] Furthermore, an abutment section is provided on the side of the widening section away from the limiting section. The abutment section is fixed to the side of the widening section facing the first sidewall. The space between the abutment section and the limiting section is used for the optical fiber cable to pass through.

[0014] Furthermore, a plurality of partition plates are fixed at intervals on the side of the widening section that is coplanar with the first sidewall of the supporting strip, and the partition plates are disposed in the area between the abutting section and the limiting section.

[0015] Furthermore, the depth of the mounting groove is not less than 1 / 3 of the thickness of the support strip.

[0016] Furthermore, the mounting groove is inclined toward the mounting space, and the mounting protrusion is inclined to match the mounting groove.

[0017] The present invention can achieve the following beneficial effects:

[0018] 1. The ruler tool of this application can bend the support strip and insert the mounting protrusion at one end of the support strip into the mounting groove at the other end to make the support strip present a ring shape with different radii. Then, the optical fiber cable is wrapped around the surface of the support strip and the optical fiber cable is limited by the installation space, thereby realizing the storage of the optical fiber cable. Furthermore, the bending radius of the support strip can be adjusted to adjust the bending arc of the stored optical fiber cable.

[0019] 2. The first and second clips are set so that the width of the installation space is greater than the width of the support strip, so that the optical fiber cable can be stored in the setting area of ​​the first and second clips. This makes it easier for the optical fiber cable to bypass the widening section when it is wound in multiple layers.

[0020] 3. By setting the mounting groove and mounting protrusion at corresponding inclinations and limiting the opening depth of the mounting groove, the installation and fixing stability of both ends of the support strip can be improved, and it is not easy to come apart when winding and supporting optical fiber cables.

[0032] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0033] like Figures 1 to 7As shown, a ruler tool for adjusting the bending arc of an optical fiber includes a support strip 1. When naturally extended, the support strip 1 has a toothed, elongated shape and is flexible enough to bend. The support strip 1 includes several basic segments 11 along its length. Each basic segment 11 includes a sequentially arranged mounting protrusion 14, mounting groove 13, and mounting space 12. When using the support strip 1 to store the optical fiber cable 100, the mounting protrusion 14 at one end of the support strip 1 is inserted into the mounting groove 13 of the corresponding basic segment 11 at the other end to bend the support strip 1. At this time, the optical fiber cable 100 is wrapped around the support strip 1, allowing for storage of optical fiber cables with different bending arcs. By adjusting the connection of different basic segments 11, the bending arc of the support strip 1 can be adjusted, thereby controlling the bending arc of the stored optical fiber cable 100.

[0034] Specifically, the support strip 1 includes a first sidewall and a second sidewall disposed opposite to it. The mounting groove 13 is formed on the first sidewall of the support strip 1, and the mounting protrusion 14 is disposed on the second sidewall of the support strip 1. The mounting groove 13 includes a plurality of spaced mounting holes 131, and the mounting protrusion 14 includes a plurality of spaced mounting keys 141. The plurality of mounting keys 141 and the plurality of mounting holes 131 are configured in a one-to-one correspondence and have matching shapes.

[0035] In another specific embodiment, when the mounting groove 13 is formed, the forming depth of the mounting groove 13 is not less than 1 / 3 of the thickness of the support strip 1. Simultaneously, the mounting groove 13 is formed at an angle towards the mounting space 12, and the mounting protrusion 14 is correspondingly angled to the mounting groove 13. Furthermore, when the support strip 1 is bent and the mounting protrusion 14 at its end is inserted into the mounting groove 13 of one of the basic segments 11, multiple mounting keys 141 are spaced apart and inserted into the mounting holes 131. The mounting holes 131 are relatively deep, and the mounting holes 131 and mounting keys 141 are angled, making it difficult for the mounting protrusion 14 to detach from the mounting groove 13, thus making the connection between the mounting protrusion 14 and the mounting groove 13 more stable. It should be noted that the mounting groove 13 and the mounting protrusion 14 can be angled or perpendicular to the surface of the support strip 1.

[0036] Furthermore, the base section also includes a first retaining strip 15 and a second retaining strip 16. The first retaining strip 15 and the second retaining strip 16 are respectively fixed to the opposite side walls of the support strip 1. Both the first retaining strip 15 and the second retaining strip 16 include a widening section 151 and a limiting section 152. In a preferred embodiment, the widening section 151 has the same thickness as the support strip 1 and is coplanar with the support strip 1. The limiting section 152 is bent and connected to the end of the widening section 151 away from the support strip 1, and the limiting section 152 is bent toward the side of the support strip 1 where the mounting groove 13 is opened, thereby forming an installation space 12 between the first retaining strip 15 and the second retaining strip 16. When organizing and storing the optical fiber cable 100, the optical fiber cable 100 is wound around the surface of the support strip 1 and confined within the installation space 12, thereby realizing the storage of the optical fiber cable.

[0037] By adjusting the length of the widening section 151 or the limiting section 152, the width and depth of the installation space 12 can be adjusted to meet the storage requirements of fiber optic cables 100 with different winding turns. By setting the first clip 15 and the second clip 16, the width of the installation space 12 is greater than the width of the support strip 1, so that the fiber optic cable 100 at the end of the support strip 1 can bypass the widening section and continue to wind downwards. Even if the basic section 11 at the end of the support strip 1 is not bent or folded, it will not affect the winding of the fiber optic cable 100.

[0038] In another embodiment, an abutment section 17 is provided on the side of the widening section 151 away from the limiting section 152. The abutment section 17 is fixed to the side of the widening section 51 facing the first sidewall. The optical fiber cable is only wound and placed in the space between the abutment section 17 and the limiting section 152, thereby facilitating the optical fiber cable 100 to bypass the widening section 151 and continue to be wound. In another embodiment, a plurality of partition plates 2 are also fixed at intervals on the surface of the widening section 151. The partition plates 2 are disposed in the area between the abutment section 17 and the limiting section 152. The distance between two adjacent partition plates 2 is the width of the optical fiber cable 100. Thus, the partition plates 2 can separate the wound optical fiber cable, thereby reducing the entanglement of adjacent sections when the optical fiber cable is stored on the surface of the support plate, which would be inconvenient for later disassembly.

[0039] In addition, the support strip 1 has scale markings on the side wall that fixes the first clip 15 or the second clip 16. The scale markings are used to indicate the diameter of the ring formed after the support strip 1 is bent. The scale marking method is as follows: with the support strip 1 in its naturally extended state, taking the first basic segment 11 at the beginning of the support strip 1 as the starting unit, the scale marking is defined as follows: the distance from the scale marking position of any subsequent basic segment 11 to the scale marking position of the starting unit is regarded as the circumference of the circle. Based on this circumference, the diameter of the circle can be converted. The converted diameter of the circle is the scale marking of the target unit.

[0040] The principle of the ruler tool for adjusting the bending arc of optical fiber in this application is as follows: Before arranging the optical fiber cable 100, the support strip 1 is bent into a circle, and a number of basic segments 11 at the beginning and the same number of basic segments 11 at the end are connected to each other. At this time, the scale marked on the basic segment 11 connected to the beginning is the diameter of the circle. The diameter of the circle can be controlled by adjusting the position of the basic segment 11 connected to the end.

[0041] The fiber optic cable 100 is wound around the outer perimeter of the support strip 1. When the fiber optic cable 100 passes through the areas of the first clip 15 and the second clip 16, it must pass through the installation space 12. Since the width of the installation space 12 is greater than the width of the support strip 1, the fiber optic cable 100 at the connection point of the two ends of the support strip 1 can bypass the widening section 151 and continue to be wound downwards, while the excess unbent basic section 11 at the end of the support strip 1 remains naturally extended, thus supporting the fiber optic cable at the end. Using the ruler tool of this application, the fiber optic cable 100 can be bent into a circle with a diameter that meets the requirements, achieving better storage.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
