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.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] An SC-type duct-penetrable fiber optic connector includes a fiber optic connector body 1, a spring 2 on the outside of the fiber optic connector body 1, a ferrule 3 at one end of the fiber optic connector body 1, an SC dust cap 4 on the outside of the ferrule 3, an SC traction cap 5 slidably connected inside the ferrule 3, an SC inner frame 6 fixedly connected to the outside of the fiber optic connector body 1, an SC outer shell 7 on the outside of the SC inner frame 6, an SC optical cable 111 slidably connected inside the fiber optic connector body 1, an anti-adhesive tube 12 on the outside of the SC optical cable 111, and a ceramic ferrule 13 inside the SC traction cap 5.

[0026] The side wall of the insert tail 3 is provided with a positioning groove that is compatible with the SC traction cap 5, and one end of the SC dust cap 4 is provided with a limiting semi-ring that is compatible with the inside of the SC traction cap 5.

[0027] For example, the SC traction cap 5 slides into the positioning groove on the side wall of the insert tail shank 3, facilitating quick installation and removal of the SC traction cap 5. The use of the positioning groove ensures the precise position of the installed components, reduces cumulative dimensional errors, and improves the positional accuracy when assembling two parts. The positioning groove allows for quick and accurate repositioning of components, which is crucial for improving production efficiency and ensuring product quality. By using the positioning groove, components can be quickly installed in the predetermined position, simplifying the installation process and reducing installation time.

The limiting half-ring design allows for quick installation and removal, facilitating maintenance and replacement of components, improving work efficiency. The limiting half-ring can reduce wear on components during installation and use, extending their service life. The limiting half-ring helps to precisely control the position of components, ensuring installation accuracy.

[0028] A female sticker 8 is provided on the outside of the SC shell 7, and a female sticker 9 is adhered to the outside of the female sticker 8.

[0029] For example, the male and female stickers 8 and 9 work together, and can be repeatedly opened and closed, securely fixed, and reused thousands or even tens of thousands of times. This makes it cost-effective in long-term use. The use of the male and female stickers 8 and 9 is very simple. Just peel off the release paper on the back and stick them to various smooth and clean surfaces, such as plastics, hardware, wood, and electronic products. The hook and rough sides of the male and female stickers 8 and 9 are tightly bonded and have good adhesion. They can withstand a certain amount of tension without falling off. The male and female stickers 8 and 9 are made of various materials, such as nylon, polyester, and their mixtures. These materials have different heat resistance, flame retardancy, and environmental protection properties, and are suitable for different application scenarios.

[0030] The outer side of the female sticker 9 is fixedly connected to the limiting bracket 10, and the limiting bracket 10 is in contact with the SC dust cap 4.

[0031] For example, the female sticker 9 is installed on the limiting bracket 10, which limits the SC dust cap 4. The use of the limiting bracket 10 can reduce installation errors caused by improper human operation and improve the accuracy and consistency of installation. The design of the limiting bracket 10 can accommodate SC dust caps 4 of different sizes and shapes, providing flexible installation options.

[0032] A rivet 14 is provided on the outside of the SC optical cable 111, and an SC optical cable tube 112 is provided on the outside of the rivet 14.

[0033] For example, rivets 14 are installed inside the SC optical cable conduit 112 to facilitate the installation of the SC optical cable 111. The rivet 14 connection enables rapid installation, especially in mass production. Using rivets 14 can greatly improve installation efficiency, which is 5-10 times faster than manual riveting. Using rivets 14 can reduce material and production costs. The cost of rivets 14 is generally lower than that of screws, and the installation speed is faster, which helps to improve the competitiveness of the company's products. The rivet 14 connection provides high-strength fastening, with strong load-bearing capacity and shock resistance. Compared with traditional threaded connections and welding methods, rivet 14 connections are more convenient and faster, saving labor costs. There is no need for electric welding, grinding and other processing steps when installing rivets 14, avoiding deformation problems caused by high temperature.

[0034] An SC tail sleeve 16 is provided on the outside of the SC optical cable tube 112, and the SC tail sleeve 16 contacts the SC inner frame 6.

[0035] For example, the SC tail sleeve 16 is used to install the SC optical cable tube 112. Simultaneously, the SC tail sleeve 16 is installed on the side wall of the SC inner frame 6 to fix the SC optical cable tube 112. The SC tail sleeve 16 provides stable fixation for the SC optical cable tube 112, ensuring the optical cable maintains the correct position and angle in various environments, reducing displacement caused by vibration or external forces. The fixing function of the SC tail sleeve 16 prevents the connector from accidentally falling off, ensuring the safety and reliability of the fiber optic connection, especially in moving or vibrating environments. The design of the SC tail sleeve 16 typically allows for quick installation and disassembly, facilitating on-site maintenance and upgrades, reducing maintenance time and labor intensity. Fixing with the SC tail sleeve 16 allows for better management and cabling of optical fibers, resulting in a neater fiber optic layout that is easier to identify and maintain. The SC tail sleeve 16 provides additional protection for the end face of the fiber optic connector, preventing the intrusion of dust, oil stains, or other contaminants, thereby maintaining the performance of the fiber optic connection. The SC tail sleeve 16 is typically designed with good compatibility, adapting to various standard SC type fiber optic connectors, suitable for different application scenarios.

[0036] A pressing component 15 is provided on the outside of the SC optical cable tube 112, and the pressing component 15 contacts the SC tail sleeve 16.

[0037] For example, the clamping member 15 can firmly secure the fiber optic connector, preventing loosening of the connection due to external force or vibration, thereby ensuring the stability and reliability of the fiber optic connection. By fixing the fiber optic connector in place, the clamping member 15 helps protect the fiber end face from damage, prevents the intrusion of dust and contaminants, and maintains the performance of the fiber optic connection. The clamping member 15 is usually designed with an easy-to-disassemble structure, making the installation and maintenance of the fiber optic connector more convenient and quick. The use of the clamping member 15 enhances the mechanical strength of the fiber optic connector, enabling it to withstand various mechanical pressures in daily use, such as tension and bending. A high-quality clamping member 15 can ensure that the fiber optic connector remains stable even after multiple mating and unmating cycles. It maintains good connection performance and extends the life of the connector. In high-density fiber optic cabling environments, the crimping component 15 can help achieve compact arrangement of fiber optic connectors, save space, and increase cabling density. By precisely fixing the fiber end face, the crimping component 15 helps reduce insertion loss and return loss in fiber optic connections, thereby improving the optical performance of fiber optic connectors. The crimping component 15 is usually made of environmentally resistant materials and can adapt to different working environments, such as temperature changes and humidity, to maintain stable connector performance. In situations where rapid deployment of fiber optic connections is required, such as temporary activities or emergency repairs, the crimping component 15 can speed up the installation of fiber optic connectors and improve work efficiency.

[0038] The SC tailpiece 16 is made of nylon.

[0039] For example, nylon material has high tensile and compressive strength, enabling it to withstand loads for extended periods, while also possessing good toughness and impact resistance. The nylon SC tail sleeve 16 maintains its original mechanical strength even after repeated bending, which is highly advantageous for applications requiring frequent bending. Nylon has a high softening point and heat resistance, allowing it to be used at higher temperatures and suitable for various environmental conditions. Nylon has a smooth surface, a low coefficient of friction, and good wear resistance, which helps extend the product's service life.

[0040] Working principle: When using this utility model, the ferrule tail 3 has a positioning groove. During assembly, the ferrule and the SC inner frame 6 are precisely positioned. During use, the fiber optic connector body 1 and the SC traction cap 5 are quickly connected by a snap-fit. After passing through the pipe, the SC traction cap 5 can be quickly removed and the SC tail sleeve 16, SC inner frame 6 and SC outer shell 7 can be installed. Then it can be used normally. The pressing part 15 can firmly fix the SC optical cable 111 to prevent the connection from loosening due to external force or vibration, thereby ensuring the stability and reliability of the SC optical cable 111 connection.

[0041] Rivet 14 is installed inside the SC optical cable conduit 112 to facilitate the installation of the SC optical cable 111. The rivet 14 connection enables quick installation. The female and male stickers 8 and 9 cooperate and can be opened and closed repeatedly. The female sticker 9 is installed on the limiting frame 10, which limits the SC dust cap 4 to prevent it from falling off during installation and allowing dust to enter the device.

[0042] 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.
