Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 4As shown, an armored optical fiber jumper includes an optical cable 1, which includes a tight-fitting optical fiber 14, an armor layer 15 and a flame-retardant protective layer 16. The armor layer 15 is located on the outside of the tight-fitting optical fiber 14, and the flame-retardant protective layer 16 is located on the outside of the armor layer 15. A left connecting sleeve 2 is fixedly connected to the surface of the left end of the optical cable 1, and slots 3 are provided at both ends of the left side of the left connecting sleeve 2. Spring grooves 4 are provided on both sides of the inner side of the left connecting sleeve 2. Slide grooves 5 are provided on both sides of the top of the left connecting sleeve 2. The slide grooves 5 are connected to the spring grooves 4. Slide rods 6 are slidably connected to the inside of the slide grooves 5. Pull blocks 7 are fixedly connected to the tops of the slide rods 6. The slide rods 6 extend to the inner side of the spring grooves 4. The bottom wall of the spring slot 4 is slidably connected with a pull plate 8, the top of the pull plate 8 is fixedly connected with a spring 28, the spring 28 is located inside the spring slot 4 and sleeved on the surface of the slide rod 6, the bottom of the pull plate 8 is fixedly connected with a fixing rod 9, the bottom wall of the slot 3 is provided with a limiting slot 10, the fixing rod 9 penetrates into the interior of the slot 3 and is slidably connected with the limiting slot 10, the right end of the surface of the optical cable 1 is fixedly connected with a right connecting sleeve 11, the two ends of the right side of the right connecting sleeve 11 are fixedly connected with a plug plate 12, the plug plate 12 is slidably connected to the slot 3, the surface of the plug plate 12 is provided with a fixing hole 13, and the fixing hole 13 is slidably connected to the fixing rod 9.

[0021] refer to Figure 1 and Figure 3 A rotating sleeve 17 is provided on the surface of the limiting groove 10, and a reinforcement ring 18 is fixedly connected to the right side of the rotating sleeve 17. The surface of the reinforcement ring 18 is provided with an external thread. A reinforcement groove 19 is provided on the surface of the left side of the left connecting sleeve 2, and an internal thread is provided on the inner wall of the reinforcement groove 19. The reinforcement ring 18 is threadedly connected to the reinforcement groove 19.

[0022] As a technical optimization solution of the utility model, through the arrangement of the reinforcement ring 18 and the reinforcement groove 19, when the plug plate 12 is inserted into the slot 3, the reinforcement ring 18 is gradually aligned with the reinforcement groove 19 at the same time. At this time, the rotating sleeve 17 is rotated to screw the reinforcement ring 18 into the reinforcement groove 19, so that the connection between the two optical cables 1 is more firmly and not easy to loosen, further improving the stability of the connection.

[0023] refer to Figure 3 Annular grooves 20 are provided on both sides of the surface of the right connecting sleeve 11, and annular plates 21 are slidably connected inside the annular grooves 20. The outer sides of the annular plates 21 are fixedly connected to the inner wall of the rotating sleeve 17, and the rotating sleeve 17 is rotatably connected to the right connecting sleeve 11 through the annular plates 21.

[0024] As a technical optimization solution of the utility model, the rotating sleeve 17 is limited by the provision of the annular plate 21, thereby avoiding the problem of reinforcement failure caused by the rotating sleeve 17 being separated from the right connecting sleeve 11 during rotation.

[0025] refer to Figure 3A rolling groove 22 is provided in the middle of the surface of the right connecting sleeve 11 and the middle of the inner wall of the rotating sleeve 17. A ball 23 is rollingly connected inside the rolling groove 22. The rotating sleeve 17 and the right connecting sleeve 11 are rollingly connected through the ball 23.

[0026] As a technical optimization solution of the utility model, the setting of the ball 23 greatly reduces the friction between the rotating sleeve 17 and the right connecting sleeve 11, making the rotation of the rotating sleeve 17 easier and smoother, so that the reinforcement ring 18 can be screwed into the reinforcement groove 19 more quickly, further improving the connection speed.

[0027] refer to Figure 2 and Figure 4 The surface of the tight-sleeved optical fiber 14 is covered with a porous foam sleeve 24, which is located on the inner side of the armor layer 15. The porous foam sleeve 24 is a soft polyurethane foam sleeve. The armor layer 15 is formed by spirally winding a stainless steel belt on the porous foam sleeve 24. A reinforcement sleeve 25 is arranged between the armor layer 15 and the flame-retardant protective layer 16. The reinforcement sleeve 25 is formed by spirally twisting multiple strands of aramid fiber ropes around the outer side of the armor layer 15.

[0028] As a technical optimization scheme of the present invention, through the arrangement of the porous foam sleeve 24 and the reinforcing sleeve 25, when the optical cable 1 is bent to a large extent, the armor layer 15 at the bending point may be deformed, causing the tight-sleeved optical fiber 14 inside it to form a line contact with the deformed steel belt, thereby avoiding cutting the tight-sleeved optical fiber 14 and the flame-retardant protective layer 16, providing good protection for the tight-sleeved optical fiber 14 and the flame-retardant protective layer 16, and further improving the practicality.

[0029] refer to Figure 1 and Figure 2 A connecting plate 26 is sleeved on the surface of the slide bar 6 , and the connecting plate 26 is located at the bottom of the pull block 7 . The connecting plate 26 is fixedly connected to the slide bar 6 , and a pull ring 27 is fixedly connected to the top of the connecting plate 26 .

[0030] As a technical optimization solution of the utility model, through the setting of the connecting plate 26, the pull ring 27 can be pulled so that the connecting plate 26 can pull the two sliding rods 6 at the same time. There is no need to pull the sliding rods 6 separately, which will affect the connection speed, making the connection simpler and faster.

[0031] The working principle and use process of the utility model are as follows: when in use, the user pulls the pull ring 27 to make the connecting plate 26 pull the two sliding rods 6 upward at the same time, and then inserts the plug plate 12 on the right side of the other optical cable 1 into the slot 3, and the pull plate 8 moves upward to squeeze the spring 28 to make it contract, and then the pull plate 8 drives the fixing rod 9 to move upward and slide out of the slot 3. At this time, the plug plate 12 is completely inserted into the slot 3 and the pull block 7 is released, so that the spring 28 is stretched to push the fixing rod 9 into the fixing hole 13 to complete the connection and fixation. When the plug plate 12 is inserted into the slot 3, the reinforcement ring 18 is gradually aligned with the reinforcement groove 19 at the same time. At this time, the rotating sleeve 17 is rotated to screw the reinforcement ring 18 into the reinforcement groove 19, so that the connection between the two optical cables 1 is more secure and not easy to loosen.
