Description

Technical Field

[0001] This utility model relates to the field of optical fiber transmission structure technology, specifically to a high-efficiency optical fiber transmission structure. Background Technology

[0002] Laser communication is a communication method that uses lasers to transmit information. Lasers are a new type of light source with characteristics such as high brightness, strong directionality, good monochromaticity, and strong coherence. According to the different transmission media, it can be divided into atmospheric laser communication and fiber optic communication. Atmospheric laser communication uses the atmosphere as the transmission medium, while fiber optic communication uses optical fibers to transmit optical signals.

[0003] The advantages of fiber optic transmission today are high transmission speed and stability. However, if the fiber optic cables on the market are not properly connected, it can easily lead to a decrease in data transmission speed or even transmission errors. In addition, traditional fiber optic cables can break or crack when subjected to external pressure or bending. To address these issues, we have proposed a high-efficiency fiber optic transmission structure. Utility Model Content

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.

[0026] Please see Figure 1-7 A high-efficiency optical fiber transmission structure includes a connector 1, a sealing ring 3, a connector 2 4, an internal tapered thread sleeve 5, and a wire assembly composed of optical fiber 1 2 and optical fiber 2 6. The internal connecting wire assemblies of connector 1 and connector 2 4 are provided with wire mating tube 1 10 and wire mating tube 2 13. The outer side of optical fiber 1 2 is bonded to the inner wall of wire mating tube 1 10, and the outer side of optical fiber 2 6 is bonded to the inner wall of wire mating tube 2 13. A sealing ring 3 is provided between connector 1 and connector 2 4, and an internal tapered thread sleeve 5 is fitted on the outer side of connector 2 4.

[0027] Furthermore, one end face of connector 1 corresponding to connector 2 4 is provided with an external tapered thread 7, and the other end face of the external tapered thread 7 opposite to connector 2 4 is provided with an annular block that fits with the sealing ring 3. The external tapered thread 7 at one end of connector 1 corresponding to connector 2 4 is provided with a mating block 8, and two symmetrically distributed positioning ports 9 are opened on the side of the mating block 8. The mating block 8 with positioning ports 9 is connected with the mating cover 11 with positioning block 12, which effectively ensures the reliability and concentricity of the optical fiber connection, ensures the accuracy of the docking, and prevents data transmission errors and rate reduction.

[0028] Furthermore, the end face of connector 2 4 corresponding to connector 1 1 is provided with a mating cover 11 that mates with mating block 8, and the mating cover 11 is provided with two positioning blocks 12 that mate with positioning port 9. The position of connector 2 4 corresponding to the internal tapered thread sleeve 5 is provided with a connecting block 14, and the end of the connecting block 14 corresponding to the mating cover 11 is provided with a set of six reinforcing ribs distributed in a ring at equal intervals. The end face of the connecting block 14 opposite to the mating cover 11 is provided with a sealing groove 15 concentric with the wire mating tube 2 13. The reinforcing ribs provided on the connecting block 14 effectively ensure the overall support of the transmission structure and effectively ensure the reliability of the connection.

[0029] Furthermore, the internal tapered thread sleeve 5 is a hollow cylinder, and the center of the end face of the internal tapered thread sleeve 5 facing away from the connector 1 has a circular hole that connects with the connector 2 4. The end face of the internal tapered thread sleeve 5 facing away from the connector 1 has a rubber block 23 that contacts and engages with the sealing groove 15. The internal tapered thread sleeve 5 has an internal tapered thread 22 that connects with the external tapered thread 7. The cylindrical exterior of the internal tapered thread sleeve 5 has a set of equally spaced mating grooves 21. After the external tapered thread 7 and the internal tapered thread 22 are connected, the sealing ring 3 is in a compressed state. The compressed rubber block 23 effectively provides pre-tightening force between the external tapered thread 7 and the internal tapered thread 22, while ensuring the internal sealing performance.

[0030] Furthermore, the optical fiber cable 12 consists of four parts: a protective layer 19, a limiting member 16, a reinforcing core 18, and five fiber cores 17 arranged in a ring at equal intervals. Inside the protective layer 19, there is a solid cylindrical rod composed of the limiting member 16, the fiber cores 17, and the reinforcing core 18. The protective layer 19 can effectively isolate and protect the internal fiber cores 17, and the reinforcing core 18 can effectively prevent the optical fiber from breaking due to large bending, thus improving its service life.

[0031] Furthermore, the center of the limiting member 16 is provided with a mating hole 20 that connects with the reinforcing core 18, and the cylindrical side of the limiting member 16 is provided with five annularly distributed mating grooves 21 that connect with the fiber core 17 group. The limiting member 16 plays an isolation role for each fiber core 17, preventing it from being squeezed by external pressure and thus playing an effective protection role.

[0032] Working principle: The high-efficiency fiber optic transmission structure is correctly installed according to the diagram. Specifically, a corresponding connection structure is set at one end where the two fiber optic cables 1 (2) and 2 (6) are connected. A limiting component 16 and a reinforcing core 18 are provided inside fiber optic cable 12 to effectively protect the fiber core 17 group inside fiber optic cable 12, significantly improving its pressure resistance, bending resistance, and transmission efficiency. Specifically, fiber optic cable 12 is fitted and bonded inside the cable fitting tube 10 of connector 11 and is horizontal to the mating block 8 inside connector 11. Fiber optic cable 2 (6) is fitted and bonded to the cable fitting tube of connector 2 (4). The inner tapered thread sleeve 5 is placed on the second connector 4 and level with the inner surface of the mating cover 11. A sealing ring 3 is placed between the first connector 1 and the second connector 4. The inner tapered thread sleeve 5 is rotated towards the first connector 1, that is, the inner tapered thread 22 of the inner tapered thread sleeve 5 is engaged with the outer tapered thread 7 of the first connector 1. At this time, the sealing ring 3 is in a compressed state, and the rubber block 23 inside the inner tapered thread sleeve 5 is also in a compressed state. The compressed sealing ring 3 and the rubber block 23 simultaneously provide pre-tightening force between the inner tapered thread 22 and the outer tapered thread 7, effectively ensuring the reliability and sealing of the connection.
