Description

Technical Field

[0001] The utility model relates to the technical field of fiber optic jumpers, and more specifically, to a fiber optic jumper with tensile strength. Background Art

[0002] A fiber optic jumper is a jumper wire used to connect from a device to a fiber optic cabling link. It has a relatively thick protective layer and is generally used for the connection between an optical terminal and a terminal box. It is applied in some fields such as fiber optic communication systems, fiber optic access networks, fiber optic data transmission, and local area networks.

[0003] After retrieval, the utility model patent with the publication number of CN215728945U discloses a retractable fiber optic jumper, which includes a fiber optic body and connection terminals at both ends thereof. A spiral part is provided in the middle of the fiber optic body, and the cross-section of the spiral part is rectangular. The spiral part includes a sheath and a tensile rope, and the sheath wraps outside the tensile rope and the fiber optic body. The middle section of the fiber optic jumper in this patent is designed to be spiral, enabling the fiber optic jumper to stretch to a certain extent through the elasticity of the spiral part to adapt to different distance usage scenarios. The cross-section of the spiral part is rectangular, which can effectively prevent the spiral parts of each fiber optic jumper from winding around each other during multiple uses and storage, making the fiber optic jumper easy to manage.

[0004] However, the above patent still has the following deficiencies: Although the spiral fiber optic jumper can stretch, it cannot store the jumper in the spiral part, and entanglement is likely to occur. In addition, when the spiral part of the fiber optic jumper is fully stretched, it is not easy to ensure the tensile strength of the fiber optic jumper at this time. For this reason, we propose a fiber optic jumper with tensile strength. Summary of the Utility Model

[0005] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a fiber optic jumper with tensile strength.

[0006] To solve the above problems, the utility model adopts the following technical solutions:

[0007] A fiber optic jumper with tensile strength includes a fiber optic wire. The middle part of the fiber optic wire is set as a spiral section, and the two ends of the fiber optic wire are respectively set as straight sections. Connection terminals are fixedly connected to the ends of the two straight sections respectively. Reinforcing mechanisms are respectively arranged outside the two straight sections. One end of the spiral section is fixedly sleeved with an outer sheath, and the other end of the spiral section is fixedly sleeved with an inner sheath. The end of the inner sheath is movably sleeved into the inner cavity of the outer sheath and fixedly connected with a movable ring. The side surface of the movable ring is in contact with the inner wall of the outer sheath, and the spiral section is located in the inner cavities of the outer sheath and the inner sheath.

[0008] As a preferred embodiment of the present utility model, the strengthening mechanism includes a plurality of rubber reinforcing ribs fixedly connected to the side surface of the straight section, and a reinforcing soft steel wire is fixedly sleeved inside each of the plurality of rubber reinforcing ribs.

[0009] As a preferred embodiment of the present utility model, both the outer sheath and the inner sheath are made of transparent silica gel material.

[0010] As a preferred embodiment of the present utility model, an optical fiber is arranged in the middle of the optical fiber line.

[0011] As a preferred embodiment of the present utility model, the outer diameter of the spiral section is smaller than the inner diameters of the outer sheath and the inner sheath.

[0012] As a preferred embodiment of the present utility model, one end of the rubber reinforcing rib is connected to the connection terminal, and the other end of the rubber reinforcing rib is connected to the outer sheath or the inner sheath.

[0013] Compared with the prior art, the advantages of the present utility model are as follows:

[0014] In the present utility model, through the cooperation of the outer sheath, the inner sheath and the movable ring, the spiral section in the middle of the optical fiber line is protected and stored, avoiding winding of the spiral section. At the same time, when the spiral section is stretched, the outer sheath and the inner sheath are driven to slide synchronously; secondly, when the movable ring abuts against one end of the inner cavity of the outer sheath, it means that the spiral section is in a fully stretched state, and the cooperation of the outer sheath, the inner sheath and the movable ring is used to bear the pulling force at this time; in addition, rubber reinforcing ribs and reinforcing soft steel wires are arranged on the outer side of the straight section to enhance the tensile strength of the straight section of the optical fiber line, improving the working quality of the anti-pulling optical fiber jumper.

[0024] Embodiment:

[0025] Please refer to Figures 1-4 , a tensile-resistant fiber optic jumper, including an optical fiber line 1. The middle part of the optical fiber line 1 is set as a spiral section 3, and both ends of the optical fiber line 1 are set as straight sections 2. Connection terminals 7 are respectively fixedly connected to the ends of the two straight sections 2. Reinforcing mechanisms 8 are respectively arranged on the outer sides of the two straight sections 2. An outer sheath 4 is fixedly sleeved at one end of the spiral section 3, and an inner sheath 5 is fixedly sleeved at the other end of the spiral section 3. The end of the inner sheath 5 is movably sleeved into the inner cavity of the outer sheath 4 and fixedly connected with a movable ring 6. The side surface of the movable ring 6 is in contact with the inner wall of the outer sheath 4. The spiral section 3 is located in the inner cavities of the outer sheath 4 and the inner sheath 5.

[0026] Specifically, please refer to Figure 1 and Figure 3 , the reinforcing mechanism 8 includes a plurality of rubber reinforcing ribs 9 fixedly connected to the side surface of the straight section 2, and reinforcing soft steel wires 10 are fixedly sleeved inside the plurality of rubber reinforcing ribs 9.

[0027] In this embodiment, the strength of the straight section 2 is enhanced by using the rubber reinforcing rib 9 and the reinforcing soft steel wire 10.

[0028] Specifically, please refer to Figure 2 , both the outer sheath 4 and the inner sheath 5 are made of transparent silicone material.

[0029] In this embodiment, the stretching condition of the helical section 3 can be observed through the outer sheath 4 and the inner sheath 5.

[0030] Specifically, please refer to Figure 3 , an optical fiber 11 is provided in the middle of the optical fiber line 1.

[0031] Specifically, please refer to Figure 2 , the outer diameter of the helical section 3 is smaller than the inner diameters of the outer sheath 4 and the inner sheath 5.

[0032] In this embodiment, it is ensured that the helical section 3 can smoothly expand and contract in the outer sheath 4 and the inner sheath 5.

[0033] Specifically, please refer to Figure 1 and Figure 3 , one end of the rubber reinforcing rib 9 is connected to the connection terminal 7, and the other end of the rubber reinforcing rib 9 is connected to the outer sheath 4 or the inner sheath 5.

[0034] In this embodiment, it is ensured that one end of the rubber reinforcing rib 9 on each of the two straight sections 2 is respectively connected to the two connection terminals 7, and the other end of the rubber reinforcing rib 9 on the two straight sections 2 is respectively connected to the outer sheath 4 and the inner sheath 5, and the straight section 2 is strengthened by using the rubber reinforcing rib 9.

[0035] Working principle: When in use, when the two connection terminals 7 are pulled, the connection terminals 7 drive the straight section 2 to pull the helical section 3. At this time, the helical section 3 is stretched. In addition, when the helical section 3 is stretched, it drives the outer sheath 4 and the inner sheath 5 to slide relative to each other, and the sliding distance between the outer sheath 4 and the inner sheath 5 is limited by the movable ring 6. When the end face of the movable ring 6 abuts against one end of the inner cavity of the outer sheath 4, it means that the helical section 3 is in a fully stretched state. The cooperation of the outer sheath 4, the inner sheath 5 and the movable ring 6 prevents the helical section 3 from being further stretched, playing a role in anti-tensile. In addition, the rubber reinforcing rib 9 and the reinforcing soft steel wire 10 are arranged on the outer side of the straight section 2 to enhance the outer strength of the straight section 2, thereby playing a role in anti-tensile for the straight section 2, and further ensuring that the optical fiber jumper has the function of anti-tensile, which is sufficient.

[0036] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
