Description

Technical Field

[0001] This utility model belongs to the field of plug-in tool technology, specifically relating to a plug-in tool for fiber optic patch cords. Background Technology

[0002] Fiber optic patch cords are key components used to connect optical communication equipment (such as optical transceivers, switches, and routers) to fiber optic cabling links. They are equipped with connector plugs at both ends to enable flexible connection of optical paths. They mainly include LC type, SC type, FC type, ST type and MPO type.

[0003] Fiber optic patch cords are widely used in the primary and secondary equipment cabinets of converter stations. The limited space contains a dense distribution of optical fibers, making it difficult for maintenance personnel to plug and unplug fibers by hand. The narrow space makes it difficult to exert force with fingers, resulting in inconvenient operation and easy damage to the fiber optic patch cords.

[0004] Currently, fiber optic patch cords are plugged and unplugged using tools. For example, in the prior art, Chinese utility model patent CN211263854U discloses "a special plugging and unplugging tool for replaceable LC type fiber optic connectors," which includes: a detachable clamp body and a handle; the clamp body is mounted on the handle; the clamp body is characterized by: the clamp body being divided into an upper clamp arm and a lower clamp arm; the front end of the upper clamp arm having a flat surface, and a hook bending downwards from the flat surface; the front end of the lower clamp arm having a groove matching the flat surface.

[0005] While existing plugging and unplugging tools, including those mentioned above, can perform general plugging and unplugging operations, they lack a guiding structure. When unplugging fiber optic patch cords, they cannot ensure parallel unplugging, which can easily damage the plug structure of the fiber optic patch cords.

[0006] To address the aforementioned problems, this utility model proposes a tool for plugging and unplugging fiber optic patch cords. Utility Model Content

[0008] To achieve the above objectives, this utility model provides the following technical solution: a tool for plugging and unplugging fiber optic patch cords, comprising a tool body, wherein the tool body includes:

[0009] The guide ring is a semi-closed annular structure with a disassembly port for fiber optic patch cords to pass through.

[0010] Control arms, two of which are symmetrically distributed and hinged to the outer wall of the guide ring;

[0011] A C-shaped elastic sheet is fixed between the two control arms;

[0012] Clamping blocks, two of which are symmetrically distributed and mounted on opposite sides of the two control arms.

[0013] As a preferred technical solution of this utility model, an arc-shaped clamping groove is machined on the clamping surface of the clamping block.

[0014] As a preferred technical solution of this utility model, it also includes:

[0015] A rubber liner is bonded and fixed to the inner wall of the arc-shaped groove.

[0016] As a preferred embodiment of this utility model, anti-slip ridges are evenly distributed on the inner wall of the rubber liner.

[0017] As a preferred embodiment of this invention, the clamping block is detachably mounted on the control arm.

[0018] As a preferred technical solution of this utility model, it also includes:

[0019] A threaded rod is fixed to the outer wall of the clamping block, and an adjusting sliding hole is machined on the control arm for the threaded rod to pass through.

[0020] The control arm has wing nuts distributed on both sides, which are installed on the threaded rod by thread engagement.

[0021] As a preferred embodiment of this utility model, two symmetrically distributed threaded rods are fixed to the outer wall of the clamping block.

[0022] As a preferred technical solution of this utility model, it also includes:

[0023] An anti-slip rubber sleeve is fixed to the end of the control arm away from the guide ring.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] In this invention, the guide ring is C-shaped, which makes it easy to fit onto the plug of the fiber optic patch cord.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] It should be noted that since both the removal and insertion of fiber optic patch cords require clamping and fixing, and the removal and insertion operations are simply two opposite actions with identical clamping and fixing methods, this article only introduces the removal operation of fiber optic patch cords.

[0035] Please see Figures 1-4 The present invention provides the following technical solution: a tool for plugging and unplugging fiber optic patch cords, comprising a tool body 1, the tool body 1 comprising: a guide ring 11, a control arm 12, a C-shaped elastic sheet 13 and a clamping block 14.

[0036] Furthermore, by Figure 1 and Figure 2As shown, in this embodiment, the guide ring 11 is a semi-closed annular structure with a disassembly port 111 through which the fiber optic patch cord passes. Two control arms 12 are symmetrically distributed and hinged to the outer wall of the guide ring 11. A C-shaped elastic sheet 13 is fixed between the two control arms 12. Two clamping blocks 14 are symmetrically distributed and installed on the opposite surfaces of the two control arms 12. With this scheme, when the fiber optic patch cord needs to be removed, first allow the fiber optic patch cord to pass through the disassembly port 111 into the guide ring 11. Then, push the insertion / removal tool forward until the guide ring 11 is fitted onto the plug of the fiber optic patch cord. Then, press the two control arms 12 inwards. The C-shaped elastic sheet 13... 3. An elastic contraction occurs, and the two control arms 12 drive the two clamping blocks 14 to move inward. The two clamping blocks 14 clamp the plug of the fiber optic patch cord. Finally, the two control arms 12 are pulled outward, and the two control arms 12 use the two clamping blocks 14 to pull out the fiber optic patch cord. The guide ring 11 of this utility model is C-shaped, which makes it easy to put on the plug of the fiber optic patch cord. The C-shaped elastic sheet 13 is used to provide the power for the control arms 12 to flip outward and reset. At the same time, the fiber optic patch cord can pass through the C-shaped elastic sheet 13 and squeeze the control arms 12 inward so that the clamping blocks 14 clamp the plug of the fiber optic patch cord. Parallel force can be applied to plug and unplug the fiber optic patch cord, which improves the safety of plugging and unplugging the fiber optic patch cord.

[0037] Preferably, by Figure 1 , Figure 2 and Figure 4 As shown in this embodiment, an arc-shaped clamping groove 141 is machined on the clamping surface of the clamping block 14. With the above solution, when in use, the designed arc-shaped clamping groove 141 can reliably clamp optical fiber plugs of different shapes, and can stably clamp both round and square optical fiber plugs.

[0038] The arc-shaped clamp 141 has a central angle of 150°, which can accommodate fiber optic plugs of different specifications from φ2.5mm to φ3.2mm.

[0039] Preferably, by Figure 1 , Figure 2 and Figure 4 As shown, this embodiment also includes a rubber liner 5, which is bonded and fixed to the inner wall of the arc-shaped clamping groove 141. With the above solution, the fiber optic plug is clamped by the rubber liner 5 during use. The combination design of the rubber liner 5 and the arc-shaped clamping groove 141 achieves reliable fixation of the fiber optic plug through the elastic clamping structure, ensuring the stability and safety of the clamping.

[0040] The rubber liner 5 is made of EPDM rubber with a Shore hardness of 50A. Its 1.5mm wall thickness can produce a deformation of 0.8mm under a pressure of 0.3MPa, forming a dynamic clamping force.

[0041] Preferably, by Figure 1 , Figure 2and Figure 4 As shown in this embodiment, anti-slip ridges 51 are evenly distributed on the inner wall of the rubber liner 5. After adopting the above solution, when in use, multiple anti-slip ridges 51 form an anti-slip grid with a depth of 0.2mm and a spacing of 1.5mm. After the rubber liner 5 clamps the fiber optic plug, it has an anti-slip effect and can more reliably pull out the fiber optic plug.

[0042] In addition, the anti-slip grid formed by multiple anti-slip ridges 51 also has a cushioning and shock-absorbing effect, which can effectively avoid unnecessary damage caused by misoperation.

[0043] Preferably, by Figures 1-3 As shown in this embodiment, the clamping block 14 is detachably installed on the control arm 12. With the above solution, the modular design realizes the flexible assembly of the structure during use, which makes it easy to replace the damaged clamping block 14 and also easy to replace different clamping blocks 14 according to different working scenarios.

[0044] Optionally, by Figures 1-3 As shown, this embodiment also includes: a threaded rod 3 and a wing nut 4. The threaded rod 3 is fixed to the outer wall of the clamping block 14. An adjustment sliding hole 121 for the threaded rod 3 to pass through is machined on the control arm 12. Wing nuts 4 are distributed on both sides of the control arm 12 and installed on the threaded rod 3 by thread engagement. With the above solution, when in use, the cooperation between the threaded rod 3 and the wing nut 4 realizes the precise positioning and quick locking of the clamping block 14.

[0045] Among them, the threaded rod 3 adopts a Tr16×4 trapezoidal thread with a pitch accuracy of ±0.01mm. Combined with the design of the wing nut 4 (diameter φ45mm), it achieves a fine adjustment resolution of 0.1mm / turn.

[0046] The adjusting slide hole 121 has an elongated oval structure (30mm in length and 18mm in width). By loosening the wing nut 4 and moving the threaded rod 3 along the adjusting slide hole 121, the initial position of the clamping block 14 can be adjusted to meet different working scenarios.

[0047] In addition, by loosening the wing nut 4, the initial distance between the two clamping blocks 14 can be adjusted to meet different working scenarios.

[0048] Preferably, by Figures 1-3 As shown in this embodiment, two symmetrically distributed threaded rods 3 are fixed on the outer wall of the clamping block 14. With the above scheme, the design of the double threaded rods 3 can further improve the stability of the clamping block 14 during use, limit the rotational freedom of the clamping block 14, and prevent the clamping block 14 from rotating unexpectedly.

[0049] Preferably, by Figure 1 and Figure 2As shown in this embodiment, it also includes an anti-slip rubber sleeve 2, which is fixed to the end of the control arm 12 away from the guide ring 11. After adopting the above solution, the operation safety and grip comfort are improved during use.

[0050] Among them, the anti-slip rubber sleeve 2 is made of nitrile rubber with a Shore hardness of 65A, and the surface friction coefficient can reach 0.85 in a dry environment.

[0051] Components not described in detail in this article are existing technologies.

[0052] The working principle and usage process of this utility model: When using the plug-in tool of this utility model, when it is necessary to unplug the fiber optic patch cord, first let the fiber optic patch cord pass through the disassembly port 111 and enter the guide ring 11, and then push the plug-in tool forward until the guide ring 11 is fitted onto the plug of the fiber optic patch cord.

[0053] Then, the two control arms 12 are pressed inward, the C-shaped elastic sheet 13 elastically contracts, and the two control arms 12 drive the two clamping blocks 14 to move inward, using the two clamping blocks 14 to clamp the plug of the fiber optic patch cord.

[0054] Finally, pull out the two control arms 12, and use the two clamping blocks 14 to pull out the fiber optic patch cord.

[0055] The guide ring 11 of this utility model is C-shaped, which makes it easy to fit onto the plug of the fiber optic patch cord. The C-shaped elastic piece 13 is used to provide the power for the control arm 12 to flip outward and reset. At the same time, the fiber optic patch cord can pass through the C-shaped elastic piece 13 and press the control arm 12 inward so that the clamping block 14 clamps the plug of the fiber optic patch cord. Parallel force can be applied to plug and unplug the fiber optic patch cord, which improves the safety of plugging and unplugging the fiber optic patch cord.

[0056] In another aspect of this utility model, the cooperation between the threaded rod 3 and the wing nut 4 enables precise positioning and rapid locking of the clamping block 14. With the help of the adjusting slide hole 121, by loosening the wing nut 4 and moving the threaded rod 3 along the adjusting slide hole 121, the initial position of the clamping block 14 can be adjusted, and the initial distance between the two clamping blocks 14 can be adjusted to meet different working scenarios.

[0057] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
