Description

Technical Field

[0001] This utility model relates to the field of optical fiber technology, and in particular to a highly stable optical fiber with customizable channels. Background Technology

[0002] The internal structure of an optical fiber mainly consists of three parts: the core, the cladding, and the coating (or outer cladding). The transmission of optical signals between the transmission layers mainly relies on the principle of total internal reflection of the optical signal in the core. When the optical signal is emitted from the optical transmitter, it is modulated into an optical signal suitable for transmission in the optical fiber and then injected into the core. At the interface between the core and the cladding, because the refractive index of the core is higher than that of the cladding, the optical signal undergoes total internal reflection, traveling in a zigzag pattern along the core until it reaches the optical receiver. To improve the transmission efficiency of optical fibers, variable transmission channels are generally set inside the optical fiber during production for customized use, such as channels with adjustable refractive indices and adjustable filter regulators. Then, connectors are added to the ends for connection with external connectors, network devices, etc.

[0003] The existing technology has the following technical problems: When connecting optical fibers to external connectors and networks, separate connectors are required. The existing connectors are large in size when the optical fibers are formed. When connecting to external connectors, the connectors need to be installed separately. At the same time, when not in use, the ends of the optical fibers are scattered and difficult to organize, and they are prone to knotting, resulting in low regularity. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the need for separate connectors at the fiber ends and the disorganized and difficult-to-store fiber ends when not in use, by proposing a highly stable optical fiber with customizable channels.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a highly stable optical fiber with customizable channels, comprising an optical fiber body, wherein a first connector and a second connector are respectively provided at both ends of the optical fiber body, and the first connector and the second connector are interlocked with each other; a first positioning arm is provided at a symmetrical position on the circumference of the end of the first connector, and a second positioning arm is provided between adjacent first positioning arms; a limiting spring is provided at the end of both the first positioning arm and the second positioning arm, and a limiting inclined block is connected to the bottom end of the limiting spring; a first positioning groove and a second positioning groove are opened on the surface of the second connector, and a limiting inclined groove is provided on the bottom surface of both the first positioning groove and the second positioning groove.

[0006] Preferably, the first connector end has an optical fiber core sleeve at its center position, and the second connector end has an optical fiber ferrule at its center position, with the outer wall of the optical fiber ferrule and the inner wall of the optical fiber core sleeve having a clearance fit.

[0007] Preferably, the limiting groove and the bottom end of the limiting block engage with each other, the included angle between adjacent sides of the bottom end of the limiting block is a right angle, and the surface cross-section of the limiting block is triangular.

[0008] Preferably, the first positioning groove corresponds to the position of the first positioning arm, and the depth of the first positioning groove is the same as the length of the first positioning arm.

[0009] Preferably, the second positioning groove corresponds to the position of the second positioning arm, and the depth of the second positioning groove is the same as the length of the second positioning arm.

[0010] Preferably, the outer surfaces of both the first connector and the second connector are rounded, and the diameter and length of the surfaces of the first connector and the second connector are the same.

[0011] Preferably, the central axes of the first connector and the second connector coincide with the center of the end of the optical fiber body, and the adjacent limiting wedges are the same size.

[0012] Beneficial effects

[0013] In this invention, the optical fiber body is equipped with a first connector and a second connector at both ends. When storing the optical fiber body, the limiting inclined blocks on the surface of the first connector and the limiting inclined groove on the second connector are used for positioning, so that the entire optical fiber body forms a ring for neat storage, preventing damage to the ends of the optical fiber body. Multiple optical fiber bodies can be neatly stored in a circular shape. The structure is simple and facilitates the storage and organization of optical fiber bodies.

[0014] In this invention, a first connector and a second connector are provided at the end of the optical fiber body for use, allowing the optical fiber body to be directly connected to an external connector through its own connector. At the same time, the external connector can be set as the interface of the first connector or the second connector, so that the end of the optical fiber body can be directly connected to the external connector through the first connector or the second connector on its surface, without the need for a separate structure. This achieves rapid connection between the optical fiber body and the external connector, is compact, easy to install, and realizes a customizable connection channel structure for connecting and accessing the optical fiber body.

[0023] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0024] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0026] Reference Figure 1-6 A highly stable optical fiber with customizable channels includes an optical fiber body 1. The two ends of the optical fiber body 1 are respectively provided with a first connector 2 and a second connector 3, and the first connector 2 and the second connector 3 are interlocked with each other. When the optical fiber body 1 is stored, it can be positioned by the interlocking of the limiting inclined block 205 on the surface of the first connector 2 and the second connector 3 with the limiting inclined groove 304, so that the entire optical fiber body 1 forms a ring for neat storage, preventing damage to the end of the optical fiber body 1. Multiple optical fiber bodies 1 can be neatly stored in a circular shape. The structure is simple and facilitates the storage and organization of the optical fiber body 1.

[0027] To facilitate the interlocking of the first connector 2 and the second connector 3, a first positioning arm 202 is provided at a symmetrical position on the circumference of the end of the first connector 2. A second positioning arm 203 is provided between adjacent first positioning arms 202. A limiting spring 204 is provided at the end of both the first positioning arm 202 and the second positioning arm 203. A limiting inclined block 205 is connected to the bottom end of the limiting spring 204. A first positioning groove 302 and a second positioning groove 303 are formed on the surface of the second connector 3. The first positioning groove 302 and the second positioning groove 203 are connected to each other. The bottom surface of each of the two positioning slots 303 is provided with a limiting inclined groove 304. The limiting inclined groove 304 and the bottom end of the limiting inclined block 205 are engaged with each other. The included angle between adjacent sides of the bottom end of the limiting inclined block 205 is a right angle, and the surface cross-section of the limiting inclined block 205 is triangular. The first connector 2 and the second connector 3 are limited by the limiting inclined block 205 and the limiting inclined groove 304. The fiber optic ferrule 301 of the second connector 3 is inserted into the fiber optic core sleeve 201 of the first connector to achieve positional alignment. When connector 3 is inserted, the limiting wedge block 205 is pushed upwards, and the limiting spring 204 is compressed until it is fully inserted. Afterwards, the limiting wedge block 205 moves to the position corresponding to the limiting groove 304, and the limiting spring 204 rebounds, causing the limiting wedge block 205 to engage with the limiting groove 304. The elasticity of the limiting spring 204 allows the limiting wedge block 205 to automatically adapt and engage in the limiting groove 304, achieving a secure engagement connection. When disassembling the first connector 2 and the second connector 3, the first... When the first connector 2 and the second connector 3 are stretched to both sides, the side of the limiting inclined block 205 is horizontally stretched because the top of the limiting inclined block 205 is a right-angled inclined surface. During the horizontal stretching, the side of the limiting inclined groove 304 applies a horizontal force along the side of the limiting inclined block 205, providing the limiting inclined block 205 with a vertically upward component force. This causes the limiting inclined block 205 to move upward and disengage from the limiting inclined groove 304, thereby separating the first connector 2 and the second connector 3. This facilitates the quick installation and disassembly of the first connector 2 and the second connector 3.

[0028] When the first connector 2 and the second connector 3 are connected, the center position of the end of the first connector 2 is provided with an optical fiber core sleeve 201, and the center position of the end of the second connector 3 is provided with an optical fiber ferrule 301. The outer wall of the optical fiber ferrule 301 and the inner wall of the optical fiber core sleeve 201 are fitted with a gap. The gap fit between the optical fiber ferrule 301 and the optical fiber core sleeve 201 ensures the continuity and stability of optical fiber transmission. The gap design between the optical fiber ferrule 301 and the optical fiber core sleeve 201 not only ensures the smooth insertion of the optical fiber, but also avoids signal problems caused by being too tight or too loose.

[0029] Other limiting structures of the entire device are as follows: the first positioning groove 302 corresponds to the position of the first positioning arm 202, and the groove depth of the first positioning groove 302 is the same as the length of the first positioning arm 202; the second positioning groove 303 corresponds to the position of the second positioning arm 203, and the groove depth of the second positioning groove 303 is the same as the length of the second positioning arm 203; the outer surfaces of the first connector 2 and the second connector 3 are both rounded; the surface diameter and length of the first connector 2 and the second connector 3 are the same; the central axis of the first connector 2 and the second connector 3 coincides with the center position of the end of the optical fiber body 1, ensuring the consistency of the surface dimensions after the first connector 2 and the second connector 3 are connected and assembled, preventing additional protrusions or uneven positions on the surface, so that each positioning arm of the first connector 2 is in clearance fit with each positioning groove of the second connector 3, increasing surface friction and regularity; adjacent limiting wedges 205 are the same size, ensuring that their central axis coincides with the center position of the end of the optical fiber body 1, so as to ensure the straightness and stability of optical fiber transmission. Specific Implementation Example 2:

[0031] Reference Figure 1-6 When the first connector 2 and the second connector 3 are in use, the fiber core sleeve 201 and the fiber ferrule 301 on the same fiber body 1 cannot transmit signals. When the first connector 2 and the second connector 3 are stored and used in the same fiber body 1, only the ends are engaged. Whether signal transmission can be carried out can be controlled by controlling the material of the fiber core sleeve and the fiber ferrule 301.

[0032] When the fiber optic body 1 is connected to external connectors, devices, networks, etc., the end is connected through the first connector 2 or the second connector 3. In use, if the fiber optic body 1 is equipped with the first connector 2 at the end, the corresponding connector, such as the MPO connector, will have the second connector 3 at the end for quick access. Other devices use the same interface setting method. By setting the connector structure of a specified model, a customizable connection channel structure for connecting the fiber optic body 1 can be realized.

[0033] In summary:

[0034] 1. The optical fiber body 1 is equipped with a first connector 2 and a second connector 3 at both ends. When storing the optical fiber body 1, the limiting inclined block 205 on the surface of the first connector 2 and the second connector 3 engages with the limiting inclined groove 304 to position the entire optical fiber body 1 into a circular ring for easy storage. This prevents damage to the ends of the optical fiber body 1 and allows multiple optical fiber bodies 1 to be stored in a neat circular shape. The structure is simple and facilitates the storage and organization of the optical fiber body 1.

[0035] 2. The fiber optic body 1 is equipped with a first connector 2 and a second connector 3 at its end. This allows the fiber optic body 1 to be directly connected to an external connector via its own connectors. The external connector can be configured as an interface for either the first connector 2 or the second connector 3, allowing the fiber optic body 1 to be directly connected to the external connector via the first connector 2 or the second connector 3 on its surface. No separate structure is required, enabling rapid connection between the fiber optic body 1 and the external connector. The design is compact, easy to install, and provides a customizable connection channel structure for connecting the fiber optic body 1.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.
