Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber jumpers, in particular to an optical fiber jumper structure with a protective function. Background Art

[0002] This section is intended to provide background or context for the embodiments of the utility model set forth in the claims. The descriptions herein may include concepts that may be explored, but not necessarily concepts that have been previously thought of or explored. Therefore, unless otherwise noted herein, the content described in this section is not prior art with respect to the specification and claims of this application, and is not admitted to be prior art by inclusion in this section.

[0003] The fiber optic patch cord structure usually includes a fiber optic connector and an optical cable, and the corresponding end of the optical cable is directly installed with the corresponding fiber optic connector. When connecting the optical cable to the corresponding optical fiber connector, it is necessary not only to insert the optical fiber into the optical fiber connector to transmit the optical signal normally, but also to use a fixed sleeve to crimp the optical cable, thereby ensuring the connection strength between the optical cable and the optical fiber connector and improving the tensile strength of the entire fiber optic patch cord structure.

[0004] Fiber optic patch cords are used to connect devices to fiber optic cabling links. They have a thicker protective layer and are generally used to connect optical terminals and terminal boxes. They are used in fiber optic communication systems, fiber optic access networks, fiber optic data transmission, and local area networks.

[0005] In the process of connecting the optical cable and the optical fiber connector, in order to prevent the cable sheath of the optical cable from coming out of the fixing sleeve, the connection can be strengthened by glue fixation. In the specific operation, the fixing sleeve set on the rear end of the connector housing is first crimped and fixed to the connector housing by the crimping fixing process, and then glue is applied at the position where the rear end of the fixing sleeve is connected to the optical cable. After the glue is cured, the fixing sleeve and the cable sheath of the optical cable can be fixed together, thereby enhancing the connection strength between the optical cable and the fixing sleeve.

[0006] And because fiber optic patch cords need to be used in different environments, traditional fiber optic patch cords are prone to aging due to ultraviolet rays during use, thus affecting the signal transmission quality of the optical patch cords. At the same time, because fiber optic patch cords need to pass through different line structures during installation and use, they often need to be bent for use. After bending, general fiber optic patch cords are not only easily deformed, but also the internal structure is easily damaged, affecting their use. Utility Model Content

[0007] The utility model aims to provide an optical fiber jumper structure with a protective function, which can avoid excessive bending of an optical cable and improve the bonding effect.

[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] A fiber optic jumper structure with a protective function comprises an optical cable connector, a plurality of optical cables are fixed at one end of the optical cable connector, a cable sheath is sheathed outside the optical cable, an anti-ultraviolet coating layer is bonded to the cable sheath away from the optical cable, the cable sheath is fixed to the optical cable connector, the cable sheath is a layered structure, comprising an inner layer close to the optical cable, a reinforcing elastomer is fixed to the inner layer away from the optical cable, a plurality of reinforcing elastomers are equidistantly arranged along the edge of the inner layer, and an outer layer is fixed to the end of the reinforcing elastomer away from the inner layer.

[0010] Furthermore, the distance between the inner layer and the optical cable is 5-8 mm.

[0011] By adopting the above technical solution, there is a gap between the inner layer and the optical cable, which avoids direct squeezing of the internal optical cable when bending.

[0012] Furthermore, the reinforcing elastomer is made of TPU elastomer, the reinforcing elastomer is inclined, and the angle between the reinforcing elastomer and the inner layer surface is 30°.

[0013] By adopting the above technical solution, when bending externally, the bending force is transmitted to the surface of the optical cable through the cable sheath and then through the insulation surface block. Therefore, the reinforcing elastic body and the insulation surface block are used to unload the force, thereby avoiding direct bending of the optical cable and preventing the optical cable from being damaged by bending.

[0014] Furthermore, the cable sheath is provided with a groove near the optical cable connector end, the side of the groove is provided with a through hole, and a plurality of through holes are provided at equal distances along the edge of the cable sheath.

[0015] By adopting the above technical solution, the glue can be easily penetrated into the through hole during the gluing operation, thereby increasing its adhesiveness.

[0016] Furthermore, a silicone block is filled between the two reinforcing elastic bodies, and a plurality of pores are provided inside the silicone block.

[0017] Furthermore, the space between the inner layer and the optical cable is filled with heat insulating cotton blocks.

[0018] By adopting the above technical solution, the overall heat dissipation performance can be improved and the service life of the optical cable can be extended while avoiding bending and damage of the optical cable.

[0019] In summary, the beneficial technical effects of the utility model are:

[0020] 1. Reinforced elastic body and silicone block are used. When bending externally, the bending force is transmitted to the surface of the optical cable through the cable outer skin and then through the heat insulation surface block. Therefore, the reinforced elastic body and heat insulation surface block are used to unload the force, thereby avoiding direct bending of the optical cable and preventing the optical cable from being damaged by bending.

[0021] 2. The use of heat-insulating cotton blocks can improve the overall heat dissipation performance and extend the service life of the optical cable while preventing the optical cable from being bent and damaged;

[0022] 3. A groove is provided on the cable sheath near the optical cable connector end, which makes it easier for glue to penetrate into the through hole during the gluing operation, thereby increasing its adhesiveness. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0030] See also Figure 1-3The utility model provides a technical solution: a fiber optic jumper structure with a protective function, including an optical cable connector 1, a plurality of optical cables 2 are fixed at one end of the optical cable connector 1, a cable sheath 3 is provided on the outside of the optical cable 2, an anti-ultraviolet coating 4 is bonded to the cable sheath 3 away from the side of the optical cable 2, the cable sheath 3 is fixed to the optical cable connector 1, the cable sheath 3 is a layered structure, including an inner layer 5 close to the optical cable 2, a reinforcing elastomer 6 is fixed on the side of the inner layer 5 away from the optical cable 2, a plurality of reinforcing elastomers 6 are equidistantly arranged along the edge of the inner layer 5, and an outer layer 7 is fixed to the end of the reinforcing elastomer 6 away from the inner layer 5.

[0031] The distance between the inner layer 5 and the optical cable 2 is 5-8 mm.

[0032] Specifically, in this embodiment, the distance between the inner layer 5 and the optical cable 2 is 5 mm.

[0033] Meanwhile, the reinforcing elastomer 6 is made of TPU elastomer, and the reinforcing elastomer 6 is arranged at an angle, and the angle between the reinforcing elastomer 6 and the surface of the inner layer 5 is 30°.

[0034] The space between the inner layer 5 and the optical cable 2 is filled with a heat insulating cotton block 11 .

[0035] Furthermore, there is a gap between the inner layer 5 and the optical cable 2. Therefore, when bending externally, the bending force is transmitted to the surface of the optical cable 2 through the cable outer skin 3 and then through the insulation surface block. Therefore, the reinforcing elastomer 6 and the insulation surface block are used to unload the force, thereby preventing the optical cable 2 from bending directly, and preventing the optical cable 2 from being damaged by bending.

[0036] The reinforcing elastic body 6 is arranged to be inclined, so that direct contact of the reinforcing elastic body 6 can be avoided during bending, thereby facilitating overall bending and being easy to use.

[0037] A silicone block 10 is filled between the two reinforcing elastic bodies 6 , and a plurality of air holes are arranged inside the silicone block 10 , thereby increasing the heat dissipation effect of the optical cable 2 and extending its service life.

[0038] A groove 8 is further provided at the end of the cable sheath 3 close to the optical cable connector 1 , and a through hole 9 is provided on the side of the groove 8 . A plurality of through holes 9 are equidistantly provided along the edge of the cable sheath 3 .

[0039] The above structure can facilitate the glue to penetrate into the through hole 9 during the gluing operation, thereby increasing its adhesiveness.

[0040] The working principle of the utility model is as follows: an improvement is made on the existing optical jumper, wherein the optical cable connector 1 is connected to the cable sheath 3, and firstly a groove 8 is provided on the cable sheath 3 to cover the plugging position of the optical cable connector 1, and when glue reinforcement is needed, glue can be added along the through hole 9 to increase the adhesiveness.

[0041] The cable sheath 3 is set to a layered structure, and its layered structure can be used to further improve the overall resilience. At the same time, there is a gap between the cable sheath 3 and the optical cable 2, so that when bending, the bending force is transmitted to the surface of the optical cable 2 through the cable sheath 3 and then through the insulation surface block. Therefore, the reinforcing elastomer 6 and the insulation surface block are used to unload the force, thereby avoiding direct bending of the optical cable 2, and preventing the optical cable 2 from being damaged by bending.
