Abstract
Description
Technical Field
[0001] This utility model belongs to the field of patch cord tail cable reinforcement technology, specifically the patch cord tail cable reinforcement structure of optical cable junction box. Background Technology
[0002] Optical fiber junction boxes are interface devices at the junction points of backbone optical cables and distribution optical cables in optical transmission networks. They are used to realize functions such as fixing and protecting optical cables, splicing and termination of optical cables, protection of optical fiber splice points, and distribution and scheduling of optical fiber lines. With the development of communication technology, especially the construction of 5G and the growth of demand in the home broadband market, the demand for optical fiber cables has increased significantly. As a key node device in optical fiber networks, the importance of optical fiber junction boxes is becoming increasingly prominent.
[0003] Meanwhile, the fiber optic patch cord tail cable fixing anti-pull quick connector with announcement number CN217305608U was also disclosed. It is related to the field of fiber optic patch cords and includes fiber optic patch cords and fixing anti-pull components. The fiber optic patch cord includes a connecting strip, a shell and a cable. The bottom of the shell is equipped with a locking strip. The fixing anti-pull components include a fixing plate, a strong double-sided adhesive, an upper limit block, a lower limit block, a limit groove and a connecting rod.
[0004] The aforementioned fiber optic patch cord tail cable fixing anti-pull quick connector has a large overall structure. During use, the main body needs to be fixed and there is a large displacement space between it and the patch cord tail cable. This results in the patch cord tail cable still having a certain amount of movement space during use, which may cause the connection end between the tail cable and the connector to break.
[0005] Therefore, a reinforcement structure for the jumper tail cable of the optical cable junction box is proposed to address the above problems. Utility Model Content
[0006] To address the problems mentioned in the background art, this utility model provides a patch cord tail cable reinforcement structure for an optical cable junction box. This structure reinforces the overall structure of the tail cable and the junction plug, and uses an extended collar structure for positioning, thus avoiding bending and breakage.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a patch cord tail cable reinforcement structure for an optical cable junction box, including a tail cable, wherein a junction plug is fixedly provided at the output end of the tail cable, and a reinforcement component is provided on the surface of the junction plug;
[0008] The reinforcement component includes a first reinforcement sleeve that abuts against the surface of the connector. A second reinforcement sleeve with the same design is attached to the surface of the first reinforcement sleeve. Both the first and second reinforcement sleeves are integrally formed with a limiting frame. The inside of the limiting frame is provided with annular sleeves that fit together.
[0009] Preferably, the outer side of the reinforcing sleeve 2 is fixedly provided with a first insert block, the inner side of the first insert block is provided with a positioning groove, the inner side of the positioning groove is provided with a positioning plate, and the outer side of the positioning plate is integrally formed with a second insert block fixed to the first reinforcing sleeve.
[0010] Preferably, the connection end of the tail cable and the connector is integrally formed with a rubber sleeve, and a reinforcing rod is provided on the outside of the rubber sleeve and sleeved on the outside of the tail cable, and the reinforcing rod is slidably disposed with the annular sleeve.
[0011] Preferably, the surface of the annular sleeve is provided with a slot, and a plug integrally formed with the adjacent annular sleeve is inserted into the inside of the slot.

[0014] Preferably, both the outer side of the first reinforcing sleeve and the outer side of the second reinforcing sleeve are provided with transverse grooves, and a cross frame integrally formed with the rubber sleeve is inserted into the inside of the transverse grooves.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. This utility model uses a reinforced sleeve design that can be flexibly spliced in the reinforced component, combined with a ring sleeve. The reinforced sleeve structure can be placed on the outside of the connector for positioning, and the ring sleeve is added to protect the relatively soft and easily broken connector and tail cable connection end, so as to reduce the risk of the connector and tail cable breaking during multiple bending.
[0017] 2. This utility model, through the addition of a rubber sleeve and a reinforcing rod structure between the connector and the tail cable, allows for quick positioning and reinforcement by inserting an external crossbar structure into the cross grooves of the first and second reinforcing sleeves, thus preventing the risk of the first and second reinforcing sleeves falling off during use.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] The following describes an embodiment of this utility model based on its overall structure.
[0028] like Figures 1 to 5 As shown, this utility model provides a jumper cable reinforcement structure for an optical cable junction box, including a jumper cable 1, a junction plug 2 fixedly provided at the output end of the jumper cable 1, and a reinforcement component 3 provided on the surface of the junction plug 2.
[0029] The reinforcement component 3 includes a first reinforcement sleeve 31 that abuts against the surface of the connector 2. The surface of the first reinforcement sleeve 31 is fitted with a second reinforcement sleeve 32 that is identical to it. The spliced reinforcement sleeve 31 and the second reinforcement sleeve 32 make positioning more convenient. The surfaces of the first reinforcement sleeve 31 and the second reinforcement sleeve 32 are integrally formed with a limiting frame 33. The inside of the limiting frame 33 is provided with an annular sleeve 38 that fits into each other. The side of the annular sleeve 38 is provided with a notch to facilitate placement and installation on the outside of the tail cable 1.
[0030] In this embodiment, the outer side of the reinforcing sleeve 2 32 is fixedly provided with a first insert block 34, the inner side of the first insert block 34 is provided with a positioning groove 37, the inner side of the positioning groove 37 is provided with a positioning plate 36, and the outer side of the positioning plate 36 is integrally formed with a second insert block 35 fixed to the first reinforcing sleeve 31. The positioning plate 36 can be inserted into the inner side of the positioning groove 37 to quickly position the first reinforcing sleeve 31 and the second reinforcing sleeve 32.
[0031] The connection end of the tail cable 1 and the connector 2 is integrally formed with a rubber sleeve 4. A reinforcing rod 5 is provided on the outside of the rubber sleeve 4 and is fitted on the outside of the tail cable 1. The reinforcing rod 5 is slidably disposed with the annular sleeve 38 to increase the connection stability between the tail cable 1 and the connector 2.
[0032] The surface of the annular sleeve 38 has a slot 39, and a plug rod 310 integrally formed with the adjacent annular sleeve 38 is inserted into the slot 39. The plug rod 310 can be inserted into the slot 39 of the annular sleeve 38 for quick positioning.
[0033] The end of the insertion rod 310 is provided with an anti-disengagement structure. The design of the anti-disengagement structure can form an interlocking structure to stably limit the insertion rod 310 inside the slot 39.
[0034] The annular sleeve 38 has a notch on its side and is made entirely of rubber. The rubber structure has a lower cost and can improve the effect of flexible protection.
[0035] Both the outer side of the first reinforcing sleeve 31 and the outer side of the second reinforcing sleeve 32 are provided with transverse grooves 312. A cross frame 311 integrally formed with the rubber sleeve 4 is inserted into the inside of the transverse groove 312. After the cross frame 311 is inserted into the inside of the transverse groove 312 for quick positioning, it can prevent the connection stability of the first reinforcing sleeve 31 and the second reinforcing sleeve 32 and prevent skewing.
[0036] Working principle and process of the patch cord tail cable reinforcement structure of the optical cable junction box:
[0037] When it is necessary to reinforce the jumper cable 1 inside the optical cable junction box, firstly, reinforced sleeve 1 31 and reinforced sleeve 2 32 are respectively attached to the surface of the junction plug 2. Since the limiting frame 33 is integrally formed on the surface of reinforced sleeve 1 31 and reinforced sleeve 2 32, they can be initially positioned. At this time, the plug 1 34 on the outside of reinforced sleeve 2 32 corresponds to the plug 2 35 on the outside of reinforced sleeve 1 31. The positioning plate 36 is inserted into the positioning groove 37 of plug 1 34 and fixedly connected with plug 2 35, so that reinforced sleeve 1 31 and reinforced sleeve 2 32 are stably combined together, tightly wrapping the junction plug 2, which prevents the junction plug 2 from loosening or falling off.
[0038] At the connection point between the pigtail cable 1 and the connector 2, an integrally molded rubber sleeve 4 provides initial protection to the connection point, reducing direct pulling and wear from external forces. A reinforcing rod 5 is fitted onto the outside of the pigtail cable 1, and slidably connected to the annular sleeve 38. Multiple annular sleeves 38 are sequentially connected by inserting a rod 310 into a slot 39. The anti-detachment structure at the end of the rod 310 prevents the annular sleeves 38 from accidentally coming off, ensuring a stable connection and forming a continuous support structure. Because the annular sleeve 38 has a notch on its side and is made of rubber, it fits tightly against the pigtail cable 1, providing uniform support for the pigtail cable 1 with the assistance of the reinforcing rod 5, preventing damage to the internal optical fibers caused by bending or shaking.
[0039] The transverse grooves 312 on the outer sides of the reinforcing sleeve 1 31 and the reinforcing sleeve 2 32 cooperate with the transverse frame 311 integrally formed by the rubber sleeve 4. The transverse frame 311 is inserted into the transverse groove 312, connecting the rubber sleeve 4 with the reinforcing sleeve 1 31 and the reinforcing sleeve 2 32 into a whole. This allows the reinforcing structure of the junction plug 2, the tail cable 1 connection part and the main body of the tail cable 1 to work together, further enhancing the reinforcement effect of the jumper tail cable 1 and ensuring the stability and reliability of the jumper tail cable 1 in the optical cable junction box during long-term use.
