[0032] In the description of this utility model, unless otherwise explicitly defined, the terms "setting", "installing", "connecting", "linking", etc. should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in combination with the specific content of the technical solution.

[0033] The following is combined Figures 1 to 4 This invention describes an optical fiber calibration and positioning fixture according to an embodiment of the present invention.

[0034] Combination Figures 1 to 4 As shown, the fiber optic calibration and positioning fixture according to an embodiment of the present invention includes a base 100, a connecting block 200, and a cover plate 300. The base 100 includes a bottom plate 110. From left to right, the upper front part of the bottom plate 110 is provided with a first connecting part 120, a mounting part 130, and a fixing part 140. The mounting part 130 has a second groove 131. The connecting block 200 is detachably installed in the second groove 131. The connecting block 200 has a plurality of mounting slots 210. The cover plate 300 is rotatably connected to the first connecting part 120. The cover plate 300 can be flipped from the left side to the upper end of the base 100. The cover plate 300 is provided with a first protrusion 310. The first protrusion 310 is adapted to flip over and cover the top of the connecting block 200. The first protrusion 310 cooperates with each mounting slot 210 to form a product mounting position.

[0035] When using the clamp, first keep the cover plate 300 in the flipped-open state, and place the optical fiber into the mounting slot 210 in the corresponding front-to-back direction. After the optical fiber is placed, flip the cover plate 300 so that the first protrusion 310 can form a product installation position with each mounting slot 210, and stably clamp the optical fiber.

[0036] It is understandable that different connector blocks 200 can be equipped with mounting slots 210 of different sizes, so that fiber optic products of different diameters can be placed, positioned, and clamped simply by changing different connector blocks 300. It is also understandable that different thicknesses of fiber optics can be fixed and clamped by setting different sized mounting slots 210 on a single connector block 200.

[0037] Understandably, when the cover plate 300 flips onto the base 100, the first protrusion 310 can enter the second groove 131 and engage with the mounting groove 210, while the fixing part 140 also contacts the cover plate 300, providing support. Understandably, because the cover plate 300 can flip onto the base 100, the width of the first protrusion 310 in the left-right direction cannot be wider than the horizontal width of the first connecting part 120 and the fixing part 140 in the left-right direction.

[0038] It is understandable that there are multiple mounting slots 210, which can accommodate multiple optical fibers of the same diameter at once.

[0039] In some specific embodiments of this utility model, the cover plate 300 is provided with a second connecting part 320, which is rotatably connected to the first connecting part 120. The first protrusion 310 is located on the left side of the second connecting part 320, and a first gasket 311 is provided on the first protrusion 310. The width of the first gasket 311 in the left-right direction is the same as the width of the connecting block 200 in the left-right direction. The first gasket 311 cooperates with each mounting groove 210 to form a product mounting position.

[0040] Combination Figures 1 to 4 As shown, in this embodiment, the first connecting part 120 is provided with a first groove 121, and the second connecting part 320 is installed in the first groove 121 and movably connected to the first connecting part 120, so that the second connecting part 320 can drive the cover plate 300 to rotate relative to the base 100, thereby enabling the first pad 311 on the first protrusion 310 to cooperate with the mounting groove 210 to form a triangular product mounting position, ensuring stable clamping while avoiding damage to the surface of the optical fiber.

[0041] It is understandable that there are multiple ways to make a movable connection. One method is to provide elastic protrusions (not shown in the figure) at both ends of the second connecting part 320 in the front-rear direction, and provide slots (not shown in the figure) on both sides of the first connecting part 120 in the first groove 121. The elastic protrusions on the second connecting part 320 can be compressed and then restored to engage with the slots in the first connecting part 120, thus achieving a rotatable movable connection. Another method is to provide slots in the front-rear direction of the second connecting part 320, and provide elastic protrusions in the front-rear direction of the first connecting part 120 facing the first groove 121. The elastic protrusions on the first connecting part 120 can be compressed and then restored to engage with the slots in the second connecting part 320. A third method is to provide through holes (not shown in the figure) in the front-rear direction for both the first and second connecting parts 120, and connect them via a rotating shaft (not shown in the figure). The rotating shaft is fixedly connected to the first connecting part 120 and movably connected to the second connecting part 320, allowing the second connecting part 320 to rotate relative to the rotating shaft and the first connecting part 120.

[0042] In some specific embodiments of this utility model, a second protrusion 330 is provided behind the first protrusion 310, and a second gasket 331 is provided behind the first gasket 311. The second gasket 331 is disposed on the second protrusion 330, and the upper end surface of the first gasket 311 is flush with the upper end surface of the second gasket 331. The first gasket 311 and the second gasket 331 are made of the same soft material.

[0043] Combination Figure 1 and Figure 2As shown, in this embodiment, the width of the first protrusion 310 in the left-right direction is the same as the width of the second protrusion 330 in the left-right direction, and the width of the first pad 311 in the left-right direction is the same as the width of the second pad 331 in the left-right direction. This design facilitates the manufacturing and processing of the fixture, and the arrangement of the second protrusion 330 and the second pad 331 can assist in clamping the optical fiber, preventing the optical fiber from being damaged by a hard collision between the rear end of the optical fiber and the cover plate 300 after the optical fiber is clamped at the front end clamping position. The first pad 311 and the second pad 331 are made of the same soft material. On the one hand, the soft material can better protect the optical fiber, and on the other hand, using the same material facilitates the processing and manufacturing of the fixture.

[0044] It is understandable that the horizontal width of the second protrusion 330 in the left-right direction may not be the same as the horizontal width of the first protrusion 310 in the left-right direction, but it cannot be wider than the horizontal width of the first connecting part 120 and the fixing part 140 in the left-right direction, to prevent failure to achieve reverse coverage. Similarly, the horizontal width of the second gasket 331 in the left-right direction may not be the same as the horizontal width of the first gasket 311 in the left-right direction, but it cannot be wider than the horizontal width of the first connecting part 120 and the fixing part 140 in the left-right direction, to prevent failure to achieve reverse coverage.

[0045] Understandably, common soft materials include sponges, silicone, and rubber.

[0046] In some specific embodiments of this utility model, a connector 400 is also included. The fixing part 140 is provided with a third groove 141, and the cover plate 300 is provided with a first through hole 340. The first through hole 340 can communicate with the third groove 141. The connector 400 can pass through the first through hole 340 and connect with the third groove 141.

[0047] Combination Figure 1 and Figure 4 As shown, in this embodiment, a third groove 141 is provided on the fixing part 140. The third groove 141 can be adapted to the first through hole 340. When the cover plate 300 is rotated and flipped to cover the base 100, the third groove 141 is exactly above the first through hole 340. The third groove 141 communicates with the first through hole 340. One end of the connector 400 can pass through the first through hole 340 and be connected to the first through hole 340, thereby fixing the relative position of the cover plate 300 and the base frame 100, and the clamping is more stable.

[0048] In some specific embodiments of this utility model, the cover plate 300 is provided with a light inlet groove 350, which is located directly behind the first protrusion 310. The width of the light inlet groove 350 in the left-right direction is wider than the width of the first protrusion 310 in the left-right direction.

[0049] Combination Figure 1 and Figure 4 As shown, in this embodiment, the design of the light inlet slot 350 can reduce the weight of the cover plate 300. It also increases the light inlet variable inside the fixture, allowing the optical fiber to receive more light sources and improving the optical fiber end face.

[0050] In some specific embodiments of this utility model, a reflective structure 150 is also provided at the lower end of the base plate 110. The reflective structure 150 is located near the rear side of the cover plate 300, combined with... Figure 4 As shown, in this embodiment, the design of the reflective structure 150 can further improve the ambient brightness when the optical fiber is fixed on the clamp.

[0051] In some specific embodiments of this utility model, the mounting part 130 is also provided with a front end protrusion structure 132, which is located on the left and right sides of the second groove 131.

[0052] Combination Figure 1 and Figure 4 As shown, in this embodiment, the design of the protrusion structure 132 can serve as a reference to determine whether the installation of the optical fiber is accurate, and protect the front end of the installed optical fiber from being damaged by impact.

[0053] In some specific embodiments of this utility model, a second through hole 111 is provided at the rear end of the base plate 110, combined with... Figure 1 The second through hole 111 facilitates the positioning and installation of the clamp on other devices, and also allows for the installation of a limiting structure on the clamp to limit and hold the clamp.

[0054] In some specific embodiments of this utility model, the mounting groove 210 is a V-shaped groove. Combined with... Figure 3 As shown, the mounting slot 210 is a V-shaped slot. When the optical fiber is placed in the mounting slot 210, the two side walls of the slot 210 can provide corresponding support to the optical fiber. On one hand, this makes the installation of the optical fiber more stable, and on the other hand, it can disperse the pressure on the optical fiber and prevent damage to the surface of the optical fiber. It can be understood that the mounting slot 210 can also be a rectangular slot, a pentagonal slot, or other slot shapes.

[0055] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
