Description

Technical Field

[0001] The present invention relates to the technical field of FC pigtail disassembly and assembly, and specifically to an FC pigtail disassembly and assembly device driven by electricity. Background Art

[0002] In highly integrated data centers, communication computer rooms and other places, the pigtails on the fiber optic distribution frame inside the cabinet are densely distributed, posing extremely high requirements for the stability and efficiency of pigtail disassembly and assembly.

[0003] However, in such a compact and complex environment, it has become extremely difficult and inefficient to manually install and remove the metal sleeve of the FC pigtail connector. The narrow space inside the cabinet limits the flexibility of the operator. On the other hand, the pigtail connectors are arranged closely, requiring extremely high operation precision. A slight mistake may damage adjacent pigtails or connectors. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide an FC pigtail disassembly and assembly device driven by electricity, aiming to solve the problem that it is difficult to operate manually when the pigtails on the fiber optic distribution frame inside the cabinet are densely distributed.

[0005] To achieve the above purpose, the present invention provides the following technical solution: an FC pigtail disassembly and assembly device driven by electricity, including a disassembly and assembly mechanism, and a handle assembly is installed on the disassembly and assembly mechanism;

[0006] The disassembly and assembly mechanism includes a columnar sleeve ring covering the outside of the FC pigtail connector. A through groove is provided on the columnar sleeve ring. A power-driven component is inserted into the columnar sleeve ring. A gear column meshing with the metal sleeve along the through groove is installed on the power-driven component. The power-driven component drives the gear column to rotate to drive the metal sleeve to adjust its position along the FC pigtail connector;

[0007] The handle assembly includes a positioning plate and an elastic structure installed on the columnar sleeve ring. A movable plate is arranged on the top surface of the columnar sleeve ring. The distance between the movable plate and the positioning plate is adjusted by the elastic change of the elastic structure. Handle structures are hinged on both the positioning plate and the movable plate.

[0008] Preferably, when the elastic structure is not squeezed, the distance between the positioning plate and the movable plate is greater than the top diameter of the FC pigtail connector. The curvatures of the positioning plate and the movable plate match the top of the FC pigtail connector. External thread threads are provided on the concave inner walls of the positioning plate and the movable plate.

[0009] Preferably, a side opening is provided on one side of the columnar sleeve ring opposite to the through groove, and the side opening penetrates the entire columnar sleeve ring from bottom to top.

[0010] Preferably, a magnetic ring sheet is embedded in the inner wall of the columnar ring, a fastening belt that is mutually attracted to the magnetic ring sheet is fixedly connected to the inner wall of the columnar ring, and one end of the fastening belt extends outward along the side opening, a hole groove plate is installed on the wall of the columnar ring with the side opening, a solid column passing through the hole groove plate is installed on the fastening belt, and a threaded sleeve is provided on the solid column.

[0011] Preferably, a raised rod is installed on the handle structure connected to the movable plate, and the handle structure switches back and forth between vertical arrangement and horizontal arrangement. When the handle structure is arranged horizontally, the raised rod overlaps the solid column and contacts the side of the threaded sleeve away from the hole groove plate.

[0012] Preferably, the inner diameter of the columnar collar changes to match the shape of the FC pigtail connector, and the diameter gradually decreases from the middle to the upper side.

[0013] Preferably, two stabilizing collars are provided on the columnar collar, and the electric drive assembly comprises a metal connecting column plugged into the two stabilizing collars, a hexagonal locking column is mounted on the metal connecting column, and an electric wrench is sleeved on the hexagonal locking column.

[0014] Preferably, the outer surface fixing sleeve of the metal connecting column is provided with an anti-skid ring, and the anti-skid ring is located between the two stabilizing rings.

[0015] By means of the above technical solution, the present invention provides an electrically driven FC pigtail disassembly and assembly device, which has at least the following beneficial effects:

[0016] 1. The present invention wraps a columnar collar on the surface of the FC pigtail connector, and docks an electric wrench on the hexagonal locking column and activates it. The rotational force generated by the columnar collar controls the gear column to rotate in a set direction through the metal connecting column. The friction between the gear column and the metal sleeve is used to tighten or loosen the FC pigtail on the cabinet. The present invention is suitable for the cabinet environment of the optical fiber distribution frame where the pigtails are densely distributed. The efficient intervention of mechanical tools effectively replaces manual operation, realizes fast and accurate disassembly and assembly of the pigtail, and significantly improves work efficiency and safety.

[0017] 2. The present invention adds two handle structures on the top of the columnar collar to form protrusions on the surface, thereby adding attachment points for subsequently holding the columnar collar, making it less likely to slip off.

[0018] 3. The present invention controls the movable plate to move toward the side where the positioning plate is located by holding the two handle structures, and cooperates with the spiral thin strip protrusions of the external thread teeth of the two to form a tight clamping effect on the edge of the top of the FC pigtail connector and the outside of the connecting line, thereby preventing the tension and torsional force generated during the disassembly and assembly of the metal sleeve from causing the connecting line to twist and unstable connection.

[0019] 4. The side opening provided in the opposite direction at the intersection area between the columnar collar and the gear column of the present invention facilitates the precise insertion of the FC fiber optic connector into the columnar collar, while ensuring the safety of the connection line.

[0020] 5. When the handle structure is placed horizontally and held firmly in the present invention, the convex rod can generate a pushing force towards one side on the threaded sleeve, thereby controlling the contraction of the fastening band into a circular shape and closely fitting the surface of the FC fiber optic connector. In cooperation with the clamping of the top edge of the FC fiber optic connector and the outer side of the connection line by the movable plate and the positioning plate, the fixing effect on the FC fiber optic connector is further enhanced, ensuring that the connection line does not twist during the subsequent rotation of the metal sleeve.

[0035] Embodiment 1

[0036] See also Figures 1-7 This embodiment proposes an electrically driven FC pigtail disassembly and assembly device, which can realize the rapid and accurate disassembly and assembly of the pigtail. The FC pigtail disassembly and assembly device is mainly composed of a disassembly and assembly mechanism 3 and a handle assembly 4 installed on the disassembly and assembly mechanism 3, and the FC pigtail connector 1 and the metal sleeve 2 are the objects to be acted on. The disassembly and assembly mechanism 3 includes a columnar sleeve 301 covering the outside of the FC pigtail connector 1. The internal diameter change of the columnar sleeve 301 is adapted to the shape of the FC pigtail connector 1, and the diameter gradually decreases from the middle to the upper side. When the FC pigtail connector 1 is combined with the disassembly and assembly mechanism 3, the distance between the outer side of the metal sleeve 2 and the inner wall of the columnar sleeve 301 is between 0.2-1CM, which is intended to avoid the collision and friction between the tooth tip part of the surface of the metal sleeve 2 and the inner wall of the columnar sleeve 301 during the disassembly and assembly of the metal sleeve 2, thereby affecting the shape.

[0037] The columnar sleeve ring 301 is provided with a through groove 3011 located outside the metal sleeve 2. Two stable sleeve rings 302 arranged vertically are welded on the columnar sleeve ring 301. The columnar sleeve ring 301 and the stable sleeve rings 302 are closely and stably connected to form an integrated structural foundation. A power drive assembly 303 is inserted into the two stable sleeve rings 302. A gear column 304 meshing with the metal sleeve 2 along the through groove 3011 is installed on the power drive assembly 303. The power drive assembly 303 drives the gear column 304 to rotate to drive the metal sleeve 2 to adjust its position along the FC fiber optic connector 1. Among them, the two stable sleeve rings 302, as key components for support and positioning, allow the lower half of the power drive assembly 303 to pass through precisely, ensuring that the power drive assembly 303 maintains a strictly vertical state, and then forming an accurate parallel alignment with the FC fiber optic connector 1 to meet the requirements of high-precision installation and removal of the FC fiber optic.

[0038] During actual application, by tightly wrapping and stabilizing the FC fiber optic connector 1 of the metal sleeve 2 to be disassembled and assembled with the columnar sleeve ring 301, and then enabling the power drive assembly 303, using the rotational force generated by it to control the gear column 304 to rotate in the set direction, through the frictional effect between the gear column 304 and the metal sleeve 2, finally driving the metal sleeve 2 to rotate upward or downward along the outer surface of the FC fiber optic connector 1, realizing the tightening or loosening operation of the FC fiber optic on the cabinet, and finally achieving the purpose of efficient and precise installation and removal of the metal sleeve 2 of the fiber optic.

[0039] Specifically, the power drive assembly 303 includes a metal connection column 3031 inserted into the two stable sleeve rings 302. A hexagonal locking column 3032 is installed on the metal connection column 3031. A power wrench 3033 is sleeved on the hexagonal locking column 3032. When the power wrench 3033 is driven, torque is transmitted through the hexagonal locking column 3032 to make the entire metal connection column 3031 rotate, and then through the frictional effect between the gear column 304 and the metal sleeve 2 on the FC fiber optic connector 1, realizing the installation and removal functions of the FC fiber optic. An anti-slip sleeve ring 3034 is fixedly sleeved on the outer surface of the metal connection column 3031. The anti-slip sleeve ring 3034 is located between the two stable sleeve rings 302, effectively preventing the power drive assembly 303 from slipping off from above due to various factors during the operation process.

[0040] Embodiment 2

[0041] The end of the FC fiber optic is cylindrical, so the hole groove on the cabinet for docking with it is circular. When driving the gear column 304 to rotate to disassemble and assemble the fiber optic, the rotational force received by the metal sleeve 2 may be transmitted to the FC fiber optic connector 1, resulting in the FC fiber optic connector 1 rotating along with the metal sleeve 2, affecting the disassembly and assembly effect of the metal sleeve 2. At the same time, the tensile force and torsional force may directly act on the fiber optic connection, causing unstable connection and even damage to the fiber optic end face.

[0042] To effectively solve this problem, as Figures 1-4 shown, the handle assembly 4 in this embodiment includes a positioning plate 401 mounted on the columnar collar 301 and an elastic structure 402. The top surface of the columnar collar 301 is provided with a movable plate 403, which adjusts the distance between it and the positioning plate 401 due to the elastic change of the elastic structure 402. When the elastic structure 402 is not squeezed, the distance between the positioning plate 401 and the movable plate 403 is greater than the top diameter of the FC fiber optic connector 1. The curvatures of the positioning plate 401 and the movable plate 403 match the top of the FC fiber optic connector 1. Handle structures 404 are hinged on both the positioning plate 401 and the movable plate 403, and external thread threads 405 are provided on the concave inner wall bodies of the positioning plate 401 and the movable plate 403.

[0043] The positioning plate 401 consists of an arc part and a connecting part. The structural form of the movable plate 403 is basically the same as that of the positioning plate 401, except that there is an arc protrusion at the bottom of the arc part in the positioning plate 401, and the thickness of the arc protrusion is the same as the distance between the side of the top of the FC fiber optic connector 1 and the inner wall at the same height of the columnar collar 301.

[0044] In the conventional operation of disassembling and assembling the metal sleeve 2, it is necessary to sleeved the disassembly and assembly mechanism 3 on the corresponding FC fiber optic connector 1, and then hold the surface of the disassembly and assembly mechanism 3 by hand, and it is necessary to control the FC fiber optic connector 1 to keep it stationary when the metal sleeve 2 is rotated subsequently. At the same time, it is also necessary to use an electric wrench 3033 to drive the metal connecting column 3031 to rotate, so as to finally achieve the purpose of driving the metal sleeve 2 to rotate upward or downward along the surface of the FC fiber optic connector 1. However, in this operation step, since the surface of the columnar collar 301 is smooth, it is easy for the staff to slip when holding its surface, and it is also necessary to manually control the FC fiber optic connector 1. The inaccuracy of manual control easily causes the FC fiber optic connector 1 not to be arranged in a strictly vertical state in the columnar collar 301, thus affecting the meshing effect with the gear column 304.

[0045] In the present embodiment, a protrusion is formed on the surface of the columnar collar 301 by adding a handle structure 404, so as to increase an attachment point for holding the columnar collar 301 later and prevent it from slipping out of the hand easily. In addition, after holding the two handle structures 404, a gripping force is applied to control one of the handle structures 404 to move toward the handle structure 404 at the other fixed position, thereby driving the movable plate 403 to move toward the direction of the positioning plate 401, until the two form a clamping effect on the edge of the top of the FC pigtail connector 1 and the outside of the connecting line, and cooperate with the spiral thin strip protrusions of the external thread teeth 405 on the inner concave walls of the two to squeeze the rubber protective sleeve on the outside of the connecting line, effectively increasing the clamping effect, and finally fixing the FC pigtail connector 1 and the connecting line at its end, preventing the tension and torsional force generated during the disassembly and assembly of the metal sleeve 2, which may cause the connecting line to twist and the connection to be unstable.

[0046] In addition, by setting the handle structure 404 in the top area where the diameter of the columnar ring 301 is the smallest, the occupied space can be saved, thereby ensuring the flexibility when holding the two handle structures 404 during actual operation in the cabinet. At the same time, the height of the top of the columnar ring 301 is consistent with the height of the connecting line on the adjacent pigtails. When the staff holds the two handle structures 404, the connecting line on the adjacent pigtails has morphological plasticity, which can effectively avoid damage to the adjacent pigtails or connectors.

[0047] Embodiment 3

[0048] like Figure 2 and Figure 5 As shown, a side opening 3012 is provided on one side of the columnar collar 301 opposite to the through groove 3011, and the side opening 3012 penetrates the entire columnar collar 301 from bottom to top. The width of the side opening 3012 is greater than the diameter of the connecting wire at one end of the FC pigtail connector 1, so as to facilitate the FC pigtail connector 1 with the metal sleeve 2 to be accurately embedded in the columnar collar 301 through the side opening 3012, and the columnar collar 301 is made of metal material, which can prevent the FC pigtail from running out along the side opening 3012 under force, and ensure that the gear column 304 can directly and effectively contact the metal sleeve 2 on the FC pigtail connector 1, thereby generating the necessary friction force, and realizing efficient and accurate installation and removal operations.

[0049] Specifically, the handle structure 404 can be controlled to switch back and forth between vertical and horizontal arrangements by applying external force when needed. When it is arranged vertically, the space occupied laterally by the device can be saved. In addition, when the handle structure 404 is arranged horizontally, its arrangement direction is consistent with the direction of the connection line from the axis of the columnar ring 301 to the through groove 3011, and is staggered with the side opening 3012.

[0050] Embodiment 4

[0051] Following the above-mentioned second embodiment, in order to further ensure the fixing effect of the FC pigtail connector 1, as shown in FIG. Figure 1 , Figures 5-7 As shown, a magnetic ring piece 305 is embedded in the inner wall of the columnar ring 301, and a fastening belt 306 that is mutually attracted to the magnetic ring piece 305 is fixedly connected to the inner wall of the columnar ring 301, and one end of the fastening belt 306 extends outward along the side opening 3012. The fastening belt 306 is composed of an iron spring piece, a silicone belt and an anti-slip protrusion. The iron spring piece ensures the attraction with the magnetic ring piece 305, and the anti-slip protrusion is used to increase the friction between the fastening belt 306 and the surface of the FC pigtail connector 1 when in contact.

[0052] A hole plate 3013 is installed on the wall of the columnar collar 301 with a side opening 3012, and a solid column 3061 passing through the hole plate 3013 is installed on the fastening belt 306. The solid column 3061 is preferably made of plastic material, which is light in texture, so that after the elastic structure 402 drives the handle structure 404 on the movable plate 403 to return to the original position, the magnetic ring piece 305 can easily absorb the fastening belt 306. A threaded sleeve 3062 is provided on the solid column 3061, and a protruding rod 4041 is installed on the handle structure 404 connected to the movable plate 403.

[0053] Under normal circumstances, the fastening belt 306 is adsorbed by the magnetic ring sheet 305, thereby expanding the size of the space enclosed by the fastening belt 306, so that the end of the subsequent FC pigtail connector 1 can pass through it accurately. After that, by adjusting the two vertically arranged handle structures 404 to a horizontal arrangement, at this time, the protruding rod 4041 installed on one of the handle structures 404 overlaps the solid column 3061 and contacts the side of the threaded sleeve 3062 away from the hole groove plate 3013. After that, in the process of holding the two handle structures 404, the protruding rod 4041 can generate a pushing force toward one side on the threaded sleeve 3062, thereby controlling one end of the fastening belt 306 to move toward the other side, shrinking the ring shape, so that the inner side with the anti-slip protrusion is tightly fitted with the outer surface of the FC pigtail connector 1, and it is limited and fixed, further ensuring the fixing effect of the FC pigtail connector 1 when the metal sleeve 2 is disassembled and assembled.

[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
