It is mainly used for the transmission of optical signals. In the field of optical cable connection, with the continuous expansion and upgrading of communication networks, higher and higher requirements are placed on the stability, reliability and convenience of optical cable connections. Optical cable connection refers to connecting the optical fibers of two or more optical cables together through specific technologies and processes to achieve continuous transmission of optical signals and ensure smooth and stable communication.

[0003] During the optical cable connection process, the optical cable is usually simply constrained and placed in a junction box, and the space in the junction box cannot be effectively utilized. When there are many optical cable connection points or a longer optical cable needs to be reserved, the optical cable coil is prone to become tangled and chaotic in the junction box. At the same time, during the wiring process, the user is required to operate in a relatively small junction box. The wiring process is cumbersome and inconvenient. For this reason, it is necessary to provide an optical cable connection multi-layer winding device and a wiring method thereof, which can quickly and orderly wind and constrain the coil, and at the same time adopt a separate installation structure, which can be quickly installed in the junction box after winding, so as to achieve the purpose of convenient and fast wiring, prevent the coil from being scattered, and facilitate disassembly and assembly.

[0007] Preferably, the surface of the driving column is slidably connected to the rotating handle, and the surface of the rotating handle is fixedly connected to a ratchet. Both sides of the inner cavity of the fixing ring are slidably connected to arc-shaped teeth, and the arc-shaped teeth are meshed with the ratchet. A second spring is welded on the opposite sides of the two arc-shaped teeth, and the end of the second spring away from the arc-shaped teeth is welded to the fixing ring.

[0008] Preferably, a third spring is sleeved on the surface of the rotating handle, and the top and bottom ends of the third spring are in sliding contact with the rotating handle and the fixing ring respectively.

[0009] Preferably, the docking assembly includes a fixed shell fixedly installed at the bottom of the inner cavity of the junction box, and both sides of the top of the bracket are fixedly connected to a limiting shell, and the inner cavity of the fixed shell is slidably connected with a wedge-shaped pin, and the wedge-shaped pin is inserted into the inner cavity of the limiting shell.

[0010] Preferably, the inner cavities of the two fixed shells on the same side are rotatably connected to a rotating handle, the front and rear ends of the rotating handle close to the fixed shell are fixedly connected to a shift plate, the inner cavity of the wedge-shaped pin is fixedly connected to a fixed column, and the shift plate is sleeved on the surface of the fixed column.

[0011] Preferably, a limiting column slidably connected to the fixed shell is fixedly connected to the side of the wedge-shaped pin away from the limiting shell, and a fourth spring is sleeved on the surface of the limiting column, one end of the fourth spring is welded to the wedge-shaped pin, and the other end of the fourth spring is welded to the inner wall of the fixed shell.

[0013] Preferably, the front side and the rear side of the driving column are fixedly connected with a synchronous insert, and the front side and the rear side of the inner cavity of the rotating handle are provided with a rectangular sliding groove adapted to the synchronous insert.

[0014] A wiring method for connecting an optical cable to a multi-layer cable coiling device, the method steps are as follows:

[0015] The first spring then pushes the clamping plate down to hold the optical fiber in place until the end of the cable is fully opened and the clamping plate is in place until the end of the cable is fully opened.

[0016] The second step is to rotate the rotating arm so that the extrusion layer plate is pressed on the top of the pressing plate located above, and then the user rotates the rotating handle. During the rotation of the rotating handle, the driving column is driven to rotate through the cooperation of the synchronous insert and the rectangular slide groove. During the rotation, the driving column drives the driving bevel gear to rotate. Due to the meshing transmission of the driving bevel gear and the stressed bevel gear, the rotating column and the rotating sleeve rotate in the opposite direction, thereby allowing the two gears to rotate in the opposite direction. At the same time, due to the meshing transmission of the gear and the rack, the two racks slide back to back, thereby allowing the two sliding plates to slide back to back. During the sliding process of the sliding plate, the two extrusion wheels are driven to move back to back. During the rolling process of the extrusion wheel on the top of the wedge seat, the extrusion layer plate is squeezed downward by the inclined surface of the wedge seat, thereby causing the extrusion layer plate to squeeze the flip layer plate and the pressing plate, so that the optical fiber coil can be stably pressed on the top of the base plate, and the optical fiber coil is further limited and locked;

[0017] After the rotating arm rotates, the threaded column is engaged in the inner cavity of the positioning hole under the drive of the rotating arm, and the threaded sleeve is rotated so that the threaded sleeve is inserted into the inner cavity of the positioning hole, and the rotating arm is limited and locked so that the rotating arm and the base plate remain parallel. During the rotation of the rotating handle, the rotating handle drives the ratchet to move the two arc-shaped teeth. After the rotating handle stops rotating, the arc-shaped teeth are stably engaged with the surface of the ratchet under the elastic force of the second spring, and the rotating handle is locked and limited, thereby preventing the rotating handle and the driving column from rotating by themselves. When the user needs to rotate the rotating handle in the opposite direction, the rotating handle is first pressed down, and the Shudie rotating handle drives the ratchet to disengage from the contact with the arc-shaped teeth. At this time, the ratchet is disengaged from the fixed column, and the rotating handle is released from the one-way lock. Finally, the rotating handle is rotated in the opposite direction, and the rotating handle drives the driving column and the driving bevel gear to rotate in the opposite direction through the synchronous insert and the rectangular slide groove;

[0018] Step 3: After the optical fiber fusion splicing and winding are completed, the user moves the base plate as a whole into the inner cavity of the junction box, and drives the bottom of the limiting shell to squeeze the top of the wedge-shaped pin. Under the action of the inclined surface of the top of the wedge-shaped pin, the wedge-shaped pin slides in the inner cavity of the fixed shell, so that the limiting column slides at the same time and compresses the fourth spring until the bottom of the base plate is completely fitted with the bottom of the inner cavity of the junction box. Under the elastic force of the fourth spring, the wedge-shaped pin is reset and engaged in the inner cavity of the limiting shell, thereby achieving the limiting fixation of the base plate.

[0019] When the user disassembles the base plate, he only needs to push the rotating handle upwards, and the rotating handle drives the shift plate to rotate. The shift plate squeezes the surface of the fixed column through its inner wall, thereby causing the wedge-shaped pin to slide in the inner cavity of the fixed shell, and at the same time causing the wedge-shaped pin to disengage from the inner cavity of the limit shell, thereby releasing the limit on the base plate, and finally taking the base plate out of the inner cavity of the junction box.

[0020] The beneficial effects of the present invention are as follows: the present invention uses the base plate, the winding assembly and the elastic clamp to coil and fix the fused optical fiber coil, then uses the flip assembly and the extrusion assembly to press and limit the coiled optical fiber coil, and finally, with the setting of the docking assembly, the base plate together with the optical fiber coil on the top thereof is installed as a whole in the inner cavity of the junction box, thereby achieving the purpose of convenient and fast wiring, preventing the coil from being scattered and facilitating disassembly and assembly.

At the same time, with the coordinated use of the rotating handle 94, the dial plate 95 and the fixed column 96, the wedge-shaped latch 93 is driven, thereby controlling the insertion and limiting or disengagement and unlocking of the wedge-shaped latch 93 and the limiting shell 92.

[0041] A wiring method for connecting an optical cable to a multi-layer cable coiling device, the method steps are as follows:

[0042] Step 1: When the cable winding device is used, a plurality of optical fibers are firstly welded by an optical fiber welding machine. After all the welding is completed, the joint position is clamped in the inner cavity of the elastic clamp 11, and then the reserved length of optical fiber is wound under the pressing plate 42. Then the user presses the pressing plate 42 downward, so that the limiting insert 44 slides in the inner cavity of the fixed tube 43, and the limiting pin 45 slides in the inner cavity of the arc-shaped limiting groove 46. At the same time, the first spring 47 is compressed until the limiting pin 45 After completely reaching the bottom of the inner cavity of the arc-shaped limiting groove 46, the user rotates the pressing plate 42 so that the pressing plate 42 drives the anti-dropping convex button 48 to reach the inner cavity of the anti-dropping clamping plate 49, releases the pressing plate 42, and the first spring 47 rebounds and drives the pressing plate 42 to move upward, so that the anti-dropping convex button 48 is engaged in the inner cavity of the anti-dropping clamping plate 49, and the winding optical fiber line is pressed and limited by the pressing plate 42. In this way, the optical fiber coils on the top of the base plate 3 and the top of the flip layer plate 41 are positioned;

[0043] Step 2: The user then rotates the rotating arm 61 so that the extrusion layer 66 is pressed against the top of the upper wire pressing plate 42, and then the user rotates the rotating handle 84. The rotating handle 84 drives the driving column 82 to rotate through the cooperation of the synchronous insert 14 and the rectangular slide 15 during the rotation process. The driving column 82 drives the driving bevel gear 83 to rotate during the rotation process. Due to the meshing transmission effect of the driving bevel gear 83 and the stressed bevel gear 89, the rotating column 71 and the rotating sleeve 72 rotate in the opposite direction, thereby causing the two gears 73 to rotate in the opposite direction. At the same time, due to the meshing transmission of the gear 73 and the rack 75, the two racks 75 slide in opposite directions, thereby allowing the two sliding plates 74 to slide in opposite directions. During the sliding process of the sliding plates 74, the two extrusion wheels 76 are driven to move in opposite directions. During the rolling process of the extrusion wheels 76 on the top of the wedge-shaped seat 77, the extrusion layer plate 66 is squeezed downward by the inclined surface of the wedge-shaped seat 77, thereby causing the extrusion layer plate 66 to squeeze the flip layer plate 41 and the pressure plate 42, so that the optical fiber coil can be stably pressed on the top of the base plate 3, and the optical fiber coil is further limited and locked;

[0044] After the rotating arm 61 rotates, the threaded column 62 is engaged in the inner cavity of the positioning hole 65 under the drive of the rotating arm 61, and the threaded sleeve 63 is rotated so that the threaded sleeve 63 is inserted into the inner cavity of the positioning hole 65, and the rotating arm 61 is limited and locked so that the rotating arm 61 and the base plate 3 remain parallel. During the rotation of the rotating handle 84, the rotating handle 84 drives the ratchet 85 to move the two arc-shaped teeth 86. After the rotating handle 84 stops rotating, the arc-shaped teeth 86 are stably engaged in the ratchet 85 under the elastic force of the second spring 87. The surface of the rotating handle 84 is locked and limited, thereby preventing the rotating handle 84 and the driving column 82 from rotating by themselves. When the user needs to rotate the rotating handle 84 in the reverse direction, the rotating handle 84 is first pressed down, and the Shudie rotating handle 84 drives the ratchet 85 to disengage from the arc-shaped locking teeth 86. At this time, the ratchet 85 is disengaged from the fixed column 96, and the rotating handle 84 is released from the one-way lock. Finally, the rotating handle 84 is rotated in the reverse direction, and the rotating handle 84 drives the driving column 82 and the driving bevel gear 83 to rotate in the reverse direction through the synchronous insert 14 and the rectangular slide groove 15.

[0045] Step 3: After the optical fiber fusion splicing and winding are completed, the user moves the base plate 3 as a whole into the inner cavity of the junction box 1, and drives the bottom of the limiting shell 92 to squeeze the top of the wedge-shaped pin 93. Under the action of the top inclined surface of the wedge-shaped pin 93, the wedge-shaped pin 93 slides in the inner cavity of the fixed shell 91, so that the limiting column 97 slides at the same time and compresses the fourth spring 98, until the bottom of the base plate 3 is completely in contact with the bottom of the inner cavity of the junction box 1. Under the elastic force of the fourth spring 98, the wedge-shaped pin 93 is reset and engaged in the inner cavity of the limiting shell 92, thereby achieving the limiting fixation of the base plate 3;

[0046] When the user disassembles the base plate 3, he only needs to push the rotating handle 94 upwards. The rotating handle 94 drives the shift plate 95 to rotate. The shift plate 95 squeezes the surface of the fixing column 96 through its inner wall, thereby causing the wedge-shaped pin 93 to slide in the inner cavity of the fixing shell 91, and at the same time, the wedge-shaped pin 93 is separated from the inner cavity of the limiting shell 92, thereby releasing the limit on the base plate 3, and finally taking the base plate 3 out of the inner cavity of the junction box 1.

[0047] In summary: the optical cable is connected to a multi-layer winding device and a wiring method thereof, through the coordinated use of the base plate 3, the winding assembly 4 and the elastic clamp 11, the optical fiber coil after fusion is wound and fixed, and then the winding optical fiber coil is pressed and limited through the coordinated use of the flip assembly 6 and the extrusion assembly 7, and finally, with the setting of the docking assembly 9, the base plate 3 together with the optical fiber coil on the top thereof is installed as a whole in the inner cavity of the junction box 1, so as to achieve the purpose of convenient and fast wiring, preventing the coil from being scattered and facilitating disassembly and assembly.

A wiring method for connecting an optical cable to a multi-layer cable coiling device, which is applied to the optical cable connection multi-layer cable coiling device according to claim 9, characterized in that: The method steps are as follows: Step 1: When the cable winding device is used, a plurality of optical fibers are firstly welded by an optical fiber welding machine. After all the welding is completed, the joint position is clamped in the inner cavity of the elastic clamp (11), and then the reserved length of optical fiber is wound under the wire pressing plate (42). Then, the user presses the wire pressing plate (42) downward, so that the limit insert (44) slides in the inner cavity of the fixed tube (43), and the limit pin (45) slides in the inner cavity of the arc-shaped limit groove (46). At the same time, the first spring (47) is compressed until the limit pin (45) completely reaches After the arc-shaped limiting groove (46) reaches the bottom of the inner cavity, the user rotates the pressing plate (42) so that the pressing plate (42) drives the anti-slipping convex button (48) to reach the inner cavity of the anti-slipping clamping plate (49), and releases the pressing plate (42). The first spring (47) rebounds and drives the pressing plate (42) to move upward, so that the anti-slipping convex button (48) is engaged in the inner cavity of the anti-slipping clamping plate (49). The winding optical fiber line is pressed and limited by the pressing plate (42). In this way, the optical fiber coils at the top of the base plate (3) and the top of the flip layer plate (41) are positioned; Step 2: The user then rotates the rotating arm (61) so that the extrusion layer (66) is pressed against the top of the upper pressure plate (42). The user then rotates the rotating handle (84). During the rotation process, the rotating handle (84) drives the driving column (82) to rotate through the cooperation of the synchronous insert (14) and the rectangular slide groove (15). During the rotation process, the driving column (82) drives the driving bevel gear (83) to rotate. Due to the meshing transmission effect of the driving bevel gear (83) and the force bevel gear (89), the rotating column (71) and the rotating sleeve (72) rotate in the opposite direction, thereby causing the two gears (73) to rotate in the opposite direction. The gear (73) and the rack (75) are meshed and driven, so that the two racks (75) slide in opposite directions, thereby enabling the two sliding plates (74) to slide in opposite directions. During the sliding of the sliding plates (74), the two extrusion wheels (76) are driven to move in opposite directions. During the rolling of the extrusion wheels (76) on the top of the wedge-shaped seat (77), the extrusion layer plate (66) is squeezed downward by the inclined surface of the wedge-shaped seat (77), thereby enabling the extrusion layer plate (66) to squeeze the flip layer plate (41) and the wire pressing plate (42), so that the optical fiber coil can be stably pressed on the top of the base plate (3), and the optical fiber coil is further limited and locked; After the rotating arm (61) rotates, the threaded column (62) is engaged in the inner cavity of the positioning hole (65) under the drive of the rotating arm (61), and the threaded sleeve (63) is rotated so that the threaded sleeve (63) is inserted into the inner cavity of the positioning hole (65), and the rotating arm (61) is limited and locked, so that the rotating arm (61) and the base plate (3) remain in a parallel state. During the rotation of the rotating handle (84), the rotating handle (84) drives the ratchet (85) to move the two arc-shaped teeth (86). After the rotating handle (84) stops rotating, the arc-shaped teeth (86) are stably engaged in the ratchet (85) under the elastic force of the second spring (87). ) surface, locking and limiting the rotating handle (84), thereby preventing the rotating handle (84) and the driving column (82) from rotating by themselves. When the user needs to rotate the rotating handle (84) in the reverse direction, the rotating handle (84) is first pressed down, and the Shudie rotating handle (84) drives the ratchet (85) to disengage from the arc-shaped latching teeth (86). At this time, the ratchet (85) and the fixed column (96) are disengaged, and the rotating handle (84) is released from the one-way lock. Finally, the rotating handle (84) is rotated in the reverse direction, and the rotating handle (84) drives the driving column (82) and the driving bevel gear (83) to rotate in the reverse direction through the synchronous insert (14) and the rectangular slide groove (15); Step 3: After the optical fiber fusion splicing and winding are completed, the user moves the base plate (3) as a whole into the inner cavity of the junction box (1), and drives the bottom of the limiting shell (92) to squeeze the top of the wedge-shaped pin (93). Under the action of the inclined surface of the top of the wedge-shaped pin (93), the wedge-shaped pin (93) slides in the inner cavity of the fixed shell (91), so that the limiting column (97) slides at the same time and compresses the fourth spring (98), until the bottom of the base plate (3) is completely in contact with the bottom of the inner cavity of the junction box (1). Under the elastic force of the fourth spring (98), the wedge-shaped pin (93) is reset and engaged in the inner cavity of the limiting shell (92), thereby achieving the limiting fixation of the base plate (3); When the user disassembles the base plate (3), the user only needs to push the rotating handle (94) upwards, and the rotating handle (94) drives the shifting plate (95) to rotate. The shifting plate (95) presses the surface of the fixing column (96) through its inner wall, thereby causing the wedge-shaped latch (93) to slide in the inner cavity of the fixing shell (91), and at the same time causing the wedge-shaped latch (93) to be separated from the inner cavity of the limiting shell (92), thereby releasing the limiting of the base plate (3), and finally taking the base plate (3) out of the inner cavity of the junction box (1).
