The end of the pull rope B23 is provided with a pull ring 18.
The working flow of the invention is as follows: in the initial state, the optical fiber 44 is not inserted into any of the guide pipes 28 on each of the docking mechanisms 6, and the accommodating groove A2 where the end of each guide pipe 28 is positioned is blocked by the sealing cover 4. The traction mechanism 14 on each docking mechanism 6 is located in the upper space of the corresponding accommodating groove A2, and the spring A22 corresponding to each limiting block 19 is in a compressed state. The spring B43 in each joint mechanism 32 is in a compressed state. The pull cord a17 and the pull cord B23 in each docking mechanism 6 are in a taut state.
When it is desired to dock the optical fibers 44 using the present invention, the appropriate height and the appropriate number of docking mechanisms 6 are selected based on the number of pairs of optical fibers 44.
All sealing caps 4 on both sides of each docking mechanism 6 are opened so that all the pipes 28 on the corresponding docking mechanism 6 are in an open state, and a splice mechanism 32 is installed at the end of each optical fiber 44, and the procedure for installing the splice mechanism 32 is as follows:
the outer skin of one end of the optical fiber 44 is stripped, the glass core 45 with proper length is exposed at one end of the optical fiber 44, the jacket B39 on the joint mechanism 32 is opened, the part, with the outer skin, of the optical fiber 44, which is nested with the inner thread jacket B40 is placed in the outer thread jacket B38 on the jacket A37, the glass core 45 of the optical fiber 44 is inserted into the sliding groove B36 on the annular sleeve 33 and is effectively butted with the thin part 42 on the glass rod B41, the jacket B39 is closed, the semi-annular outer thread jacket B38 on the jacket B39 and the semi-annular outer thread jacket B38 on the jacket A37 form a complete circular outer thread jacket B38, then the inner thread jacket B40 nested with the optical fiber 44 is screwed into the outer thread jacket B38, the optical fiber 44 is clamped and fixed under the action of the inner thread jacket A37 and the inner thread jacket B39, the glass core 45 of the optical fiber 44 is elastically bent with proper small curvature between the jacket A37 and the jacket B39 while being butted with the thin part 42 of the glass rod B41, and the glass rod 41 is ensured that the glass core 45 of the optical fiber 44 is always tightly butted with the glass rod 41. The process of attaching the splice mechanism 32 to the end of the optical fiber 44 ends.
Then, the coupling mechanism 32 attached to the distal end of the optical fiber 44 is connected to the drawing mechanism 14 placed in the accommodating groove A2 with the central axis, and the female screw sleeve a16 of the drawing mechanism 14 is screwed onto the male screw sleeve a47 of the coupling mechanism 32 to complete the connection.
The crank 27 corresponding to the traction mechanism 14 connected with the joint mechanism 32 is rocked, the crank 27 drives the corresponding winding wheel 25 to rotate through the rotating shaft 26, the winding wheel 25 winds the corresponding three pull ropes A17, the three pull ropes A17 pull the traction mechanism 14 to move into the round grooves A8 on the corresponding side of the butt joint module 7 through the guide pipe 28, and the traction mechanism 14 pulls the optical fiber 44 to move into the glass rod A31 corresponding to the corresponding round groove A8 in the guide pipe 28 through the joint mechanism 32 connected with the traction mechanism.
When the traction mechanism 14 meets three limiting blocks 19 on the inner wall of the corresponding circular groove A8 under the driving of the pull rope A17, the three limiting blocks 19 synchronously shrink towards the corresponding sliding groove A11 and compress the corresponding springs A22, and when the traction mechanism 14 passes over the three limiting blocks 19, the three limiting blocks 19 are reset instantly under the reset action of the springs A22 and make a sound. Along with the traction mechanism 14 continuing to move towards the annular groove A10 in the circular groove A8 under the drive of the pull rope A17, the annular protrusion 34 on the joint mechanism 32 meets the three limiting blocks 19 and presses the three limiting blocks 19 into the corresponding sliding grooves A11 again, and when the annular protrusion 34 on the joint mechanism 32 passes over the three limiting blocks 19, the three limiting blocks 19 are respectively reset instantly under the reset action of the corresponding springs A22 and make a second sound.
At the second sound, the glass rod B41 in the joint mechanism 32 has been butted against the glass rod a31 and slid a certain distance in the ring sleeve 33, the spring B43 is also further compressed by a certain length, and the cone ring 15 of the traction mechanism 14 also enters the ring groove a10 and abuts against the end face of the ring groove a 10.

During the process that the traction mechanism 14 drives the optical fiber 44 to move towards the circular groove A8 in the guide pipe 28 through the joint mechanism 32, dust attached to the outer side of the optical fiber 44 can be cleaned under the action of the dust blocking wool 46 on the inner wall of the guide pipe 28, so that the effect that the effective butt joint of the optical fiber 44 is influenced by the fact that the optical fiber 44 brings the dust into the guide pipe 28 and the circular groove A8 is avoided. When the optical fiber 44 is docked, if the exposed portion of the optical fiber 44 is too long, the optical fiber 44 is now delivered into the conduit 28 such that the excess portion of the optical fiber 44 is guided by the upper arch 29 of the conduit 28 into the receiving slot B30 for storage.
When the optical fibers 44 need to be removed, pull rings 18 on two pull ropes B23 corresponding to the two optical fibers 44 in butt joint are pulled, each pull ring 18 pulls the corresponding three limiting blocks 19 to shrink inwards towards the chute a11 through the pull ropes B23, the limitation of the annular protrusions 34 on the butt joint mechanism 32 is relieved, and the springs a22 corresponding to the limiting blocks 19 are further compressed.
Then, the optical fiber 44 is pulled out of the catheter 28, the optical fiber 44 drives the joint mechanism 32 and the traction mechanism 14 connected with the joint mechanism 32 to synchronously move out of the catheter 28, and the traction mechanism 14 drives the corresponding winding wheel 25 to rotate through the corresponding three pull ropes A17.
When the traction mechanism 14 reaches the guide tube 28, the acting force on the pull ring 18 is removed, and the limiting block 19 is instantaneously reset under the reset action of the spring A22.
After the pulling mechanism 14 and the coupling mechanism 32 are moved out of the catheter 28 under the pulling of the optical fiber 44, the internally threaded sleeve A16 on the pulling mechanism 14 is threaded off the externally threaded sleeve A47 on the coupling mechanism 32, thereby disconnecting the pulling mechanism 14 from the coupling mechanism 32. Then, the female screw sleeve B40 on the splice mechanism 32 is screwed off the male screw sleeve B38 on the jacket a37 and the jacket B39 to release the clamping of the optical fiber 44 by the jacket a37 and the jacket B39, and the disconnection of the splice mechanism 32 from the optical fiber 44 can be completed by taking out the optical fiber 44 from the inside of the ferrule 33.
Next, the traction mechanism 14 is placed in the upper space of the corresponding accommodation groove A2 and the sealing cover 4 is covered.
During the butt-joint process of the optical fibers 44, no matter how much external dust is, the joint mechanism 32 at the tail end of the optical fibers 44 moves in the guide pipe 28 with the dust-blocking wool 46 and performs butt-joint, so that the butt-joint mechanism 6 of the invention can realize dust-free butt-joint of the optical fibers 44.
The cabinet door 5 of the cabinet body 1 is always in a closed state in the process of abutting and disconnecting the optical fibers 44, and the cabinet door 5 is opened only under the condition that overhaul is needed in the cabinet body 1.
In summary, the beneficial effects of the invention are as follows: according to the invention, in an environment with larger dust, good blind connection of the optical fibers 44 at two sides in the cabinet body 1 can be realized under the condition that the cabinet body 1 is kept unopened, and the butt joint effect of each pair of optical fibers 44 in the cabinet body 1 is obvious, so that dust-free butt joint of the optical fibers 44 in a dust-free environment is realized.
