Description

Technical Field

[0001] This utility model relates to the field of fiber optic connector equipment technology, specifically an LC-type duct-penetrable fiber optic connector. Background Technology

[0002] Fiber optic connectors (commonly known as fiber optic patch cords) are defined by the International Telecommunication Union (ITU) as "passive components used to stably, but not permanently, connect two or more optical fibers." They are primarily used to establish non-permanent, fixed connections between devices, between devices and instruments, between devices and optical fibers, and between optical fibers themselves, and are indispensable passive components in optical communication systems. The use of connectors makes detachable connections in fiber optic communication possible, providing a testing entry point for optical fibers and facilitating the testing and maintenance of optical systems. It also provides a medium for network management, making the switching and scheduling of optical systems more flexible. With the continuous development of fiber optic user network construction, FTTH (Fiber to the Home) with fiber optic cables has rapidly become widespread, enabling indoor fiber optic connections, ensuring aesthetically pleasing interior decoration, providing greater bandwidth, enhancing network transparency regarding data formats, rates, wavelengths, and protocols, relaxing environmental and power supply requirements, simplifying maintenance and installation, and facilitating convenient and quick construction in conjunction with decoration and outdoor pipeline construction. The LC connector head features a self-locking bayonet structure, while the other end has a through-hole. During construction, the connector head is pulled through the pipeline using a steel wire, making it convenient and quick. It can accommodate pipelines with a minimum inner diameter of 4.6mm. In existing technologies, the connection between the traction cap and the main body is complex, lacks anti-reverse installation design, and does not allow for quick disassembly of the traction cap and main body, making assembly inconvenient.

[0003] For example, the authorized patent document with application number CN202322921772.6 discloses an LC-type fiber optic connector, which relates to the field of fiber optic connector technology. The key technical points of its solution are: it includes an LC-type fiber optic connector, and further includes: a fixing structure installed on both sides inside the LC-type fiber optic connector for fixing the LC-type fiber optic connector; and a disassembly structure installed inside the LC-type fiber optic connector and connected to the fixing structure for retracting the fixing structure, thereby enabling quick disassembly of the LC-type fiber optic connector; the fixing structure includes a snap-fit ​​assembly and an adjustment assembly, and the disassembly structure includes a reset assembly and a limiting assembly. The effect is that a snap-fit ​​assembly is provided inside the LC-type fiber optic connector to provide a snap-fit ​​fixing function, and the snap-fit ​​assembly is adjusted and retracted using the adjustment assembly. Simultaneously, the reset assembly and limiting assembly are used to fix and retract the snap-fit ​​assembly and adjustment assembly, thereby achieving quick assembly and disassembly of the LC-type fiber optic connector.

[0004] The aforementioned patents suffer from complex connections between the traction cap and the main body, lack anti-reverse installation design, and do not offer quick disassembly of the traction cap and the main body, making assembly inconvenient. Therefore, we need to provide an LC-type duct-penetrable fiber optic connector. Utility Model Content

Detailed Implementation

[0024] 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.

[0025] Please see Figure 1-4 This utility model provides a technical solution: an LC-type duct-penetrable fiber optic connector, comprising:

[0026] LC optical cable 1 and LC anti-adhesion tube 2 installed on one side of LC optical cable 1;

[0027] One end of the LC anti-rubber tube 2 is fitted with a socket 3;

[0028] The surface of the LC anti-adhesion tube 2 is equipped with an LC main body front sleeve 4. One end of the LC main body front sleeve 4 is provided with a pressing component 5. The pressing component 5 is located on the surface of the LC optical cable 1. The surface of the LC anti-adhesion tube 2 is equipped with an LC spring 6. One end of the LC spring 6 is snapped into an LC main body rear seat 7. One end of the LC main body rear seat 7 is in contact with one side of the pressing component 5. The LC main body front sleeve 4 is located at the right end of the LC main body rear seat 7. The surface of the LC main body front sleeve 4 is equipped with an LC traction cap 8.

[0029] A rivet 9 is installed between the LC main body rear seat 7 and the pressing part 5;

[0030] In this embodiment, the traction cap of the project is made of polymer material, and the traction cap and the main body are connected by a bayonet joint. The structure also features an anti-reverse installation design to ensure consistent installation. The main body has a positioning groove on the front sleeve, allowing for precise positioning of the ferrule and the LC front sleeve during assembly. During use, the main body and traction cap quickly connect via a bayonet joint. After passing through the pipe, the traction cap can be quickly removed and the LC outer shell 10 installed for normal use. This LC-type pipe fiber optic connector can accommodate pipes with an inner diameter ≥4.6mm, suitable for both indoor cabling and outdoor installation.

[0031] As a connector, the rivet (9) in a fiber optic connector may be used to secure various components of the connector, ensuring its stability and reliability. In some specialized fiber optic connector structures, the rivet (9) may be used to fix the fiber end face inside the connector, ensuring precise fiber alignment. In the protective structure of some fiber optic connectors, the rivet (9) may be used as a component to reinforce and protect the fiber. For example, in the protective structure of ST fiber optic connectors, rivets (9) with longitudinal through holes are used to secure the inner and outer sheaths, thereby protecting the fiber inside the connector from damage. The rivet (9) in a fiber optic connector can also provide necessary structural support, enabling the connector to withstand certain external forces and pressures, ensuring the normal operation and long-term stability of the connector.

[0032] The surface of the LC traction cap 8 is provided with an LC outer shell 10;

[0033] Specifically, the LC housing 10 is made of ceramic material. Ceramic material has remarkable hardness, which can effectively protect the fiber end face and ensure the transmission quality of optical signals. At the same time, ceramic material has high chemical stability, mechanical strength and corrosion resistance, and can adapt to various complex environments.

[0034] An LC tail sleeve 11 is mounted on the surface of the pressed part 5, and an installation slot 12 adapted to the LC tail sleeve 11 is provided at one end of the LC housing 10.

[0035] It should be noted that the tail sleeve provides necessary protection and support for the tail of the fiber optic connector, preventing damage during installation and use. Through its special structural design, the tail sleeve reduces wear and deformation of the fiber optic connector tail under stress, extending its service life. The tail sleeve is used to connect the tail of the fiber optic connector to the optical cable or other related equipment, ensuring stable transmission of optical signals. It securely fixes the fiber optic connector to the optical cable using locking devices or other methods, preventing loosening or detachment. The tail sleeve also has a certain sealing performance, preventing dust, moisture, and other impurities from entering the fiber optic connector and affecting its performance. This is crucial for keeping the fiber optic connector clean and dry. Ensuring stable optical signal transmission is crucial. In some special fiber optic connector designs, the end sleeve also serves as a guide and positioner. It guides the optical cable or fiber optic connector to be inserted into the connector socket at the correct angle and direction, ensuring accurate optical signal connection. End sleeves are widely used in various fiber optic communication systems, including fiber optic access networks, fiber optic data transmission, and local area networks. When installing and using end sleeves, it is necessary to pay attention to the compatibility of their model and specifications with the fiber optic connector to ensure that they can be correctly connected and fixed to the fiber optic connector. At the same time, it is also necessary to pay attention to the cleaning and maintenance of the end sleeve to avoid contamination or damage, which could affect the performance of the fiber optic connector.

[0036] A fixing ring 13 is fixedly installed on the surface of the LC tail sleeve 11. Two long rods 14 are fixedly installed on one side of the fixing ring 13. Limiting blocks 15 are integrally machined on the adjacent sides of the two long rods 14. Limiting seats 16 are integrally machined on the top and bottom of the LC shell 10. The limiting blocks 15 and the limiting seats 16 are engaged.

[0037] The LC tail sleeve 11 is equipped with two long rods 14 via a fixing ring 13. When the LC tail sleeve 11 is connected to the LC housing 10, the two long rods 14 on the surface of the fixing ring 13 move, and the limiting block 15 on the surface of the long rod 14 contacts the limiting seat 16, causing the long rod 14 to deform until the limiting block 15 moves to one side of the limiting seat 16. The limiting seat 16 engages with the limiting block 15 to limit it, which makes the connection between the LC tail sleeve 11 and the LC housing 10 more secure and prevents it from falling off.

[0038] Both the limiting block 15 and the limiting seat 16 are designed as inclined surfaces;

[0039] Specifically, both the limiting block 15 and the limiting seat 16 are set as inclined surfaces. When the limiting block 15 moves, the two inclined surfaces first come into contact, deforming the long rod 14 until the limiting block 15 and the vertical surface of the limiting seat 16 are engaged, completing the engagement and fixation. At the same time, the long rod 14 can be bent to separate the LC tail sleeve 11 from the LC outer shell 10.

[0040] The LC tail sleeve 11 has a pad sleeve 17 that is movably sleeved inside, and the pad sleeve 17 is sleeved on the surface of the LC optical cable 1;

[0041] It is worth noting that a gasket 17 is installed between the LC tail sleeve 11 and the LC optical cable 1. The gasket 17 tightly wraps around the optical fiber, preventing physical damage such as scratches or excessive bending during the connection process. This protection is crucial for ensuring the transmission performance and stability of the optical fiber. The gasket 17 also effectively isolates the optical fiber from harmful factors such as dust, moisture, and chemicals in the external environment, preventing these substances from corroding or contaminating the optical fiber, thereby extending its service life. The gasket 17 typically has good sealing performance, ensuring the tightness of the optical fiber connector during the connection process and preventing optical signal leakage or external interference. The fixing effect of the gasket 17 reduces the loosening of the optical fiber connector during long-term use, ensuring the stability and reliability of the connection. The design of the gasket 17 minimizes optical signal loss during the connection process, ensuring the transmission quality and efficiency of the optical signal. Different specifications and types of optical fiber connectors may require different sizes of gaskets 17 for adaptation, thereby ensuring compatibility and interchangeability between connectors.

[0042] The use of the gasket 17 can simplify the installation process of the fiber optic connector, reduce the installation difficulty and cost; it is also easy to maintain. During maintenance, the gasket 17 is easy to disassemble and replace, thereby reducing the complexity and time cost of maintenance work.

[0043] One end of the socket 3 is fitted with an LC dust cap 18;

[0044] The primary function of the LC dust cap 18 is to protect the end face of the fiber optic connector. The fiber end face is highly sensitive and easily contaminated and damaged by external factors such as dust, dirt, and moisture. Once the end face is contaminated or damaged, the transmission performance of the fiber will be affected, potentially leading to signal attenuation, decreased transmission quality, or even communication interruption. Therefore, the LC dust cap 18 effectively prevents these external factors from damaging the fiber end face, keeping it clean and intact.

[0045] The device uses a bayonet connection between the traction cap and the main body, and the structure also features an anti-reverse installation design to ensure consistent installation. The main body has a positioning groove on the front sleeve, allowing for precise positioning of the ferrule and the LC front sleeve during assembly. In use, the main body and traction cap quickly connect via the bayonet. After passing through the conduit, the traction cap can be quickly removed and the LC outer shell 10 installed for normal operation. This LC-type conduit fiber optic connector is suitable for conduits with an inner diameter ≥4.6mm, for both indoor cabling and outdoor installation.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
