Description

Technical Field

[0001] The utility model relates to the field of fiber optic adapters, specifically an LC type modular fiber optic adapter. Background Art

[0002] A fiber optic adapter, also known as an optical fiber adapter, is used to dock the same or different fiber optic active adapters in a fiber optic line, precisely dock the two end faces of the optical fiber, so that the light emitted by the laser transmitter can be maximally coupled into the optical fiber, and realize the transmission of light with very small energy loss. Most fiber optic adapters are composed of two fiber sleeves and a coupler. The two fiber sleeves are inserted into the ends of two optical fibers, and the coupler plays the role of aligning the sleeves. In addition, the coupler is often equipped with a metal or non-metal flange for easy installation and fixation of the adapter. Fiber optic adapters are widely used in various scenarios, such as data centers, local area networks, and wide area networks, etc. In a data center, fiber optic adapters are used to connect different types of fiber optic devices to improve the performance of the entire system; in a local area network, since the fiber optic interfaces used by devices from different manufacturers are different, fiber optic adapters are needed for interface conversion; in a wide area network, fiber optic adapters are often used to connect devices in WAN transmission. The LC adapter is a small fiber optic adapter and is also often used to connect devices such as fiber optic transceivers and fiber optic switches.

[0003] The existing fiber optic adapter mainly consists of a connecting sleeve, a flange, a ceramic sleeve, a metal spring piece, and a positioning sleeve. The metal spring pieces are installed on both sides of the connecting sleeve. When installed, they are clamped with other fiber optic devices. The metal spring pieces on the side of the connecting sleeve then enter the fiber optic device and make contact with the fiber optic device. Due to the elastic force generated by the metal spring pieces, the fiber optic adapter is fixed to the fiber optic device. After long-term use, the elasticity decreases. After the metal spring pieces are used multiple times, especially during frequent plugging and unplugging, their elasticity gradually decreases, which will cause the spring pieces to not be able to clamp tightly, making the connection of the fiber optic adapter loose, thus affecting the transmission quality of the optical signal. Wear and deformation: The friction between the metal spring pieces and the fiber optic sleeve will cause wear and even deformation on the surface of the spring pieces. After long-term use, this wear and deformation will accumulate, resulting in the spring pieces being unable to return to their original state, further exacerbating the loosening problem of the fiber optic adapter, reducing the stability and firmness of the fiber optic adapter, being not conducive to use, and the raw material cost of the metal spring piece material is higher. Summary of the Utility Model

[0004] In order to overcome the deficiencies of the prior art solutions, the utility model provides an LC type modular fiber optic adapter, which can effectively solve the technical problems of poor stability, poor firmness, and easy loosening of the existing fiber optic adapter.

[0005] The technical solution adopted by the present utility model to solve its technical problems is as follows: an LC-type modular fiber optic adapter, including a housing and a sleeve. The sleeve is fixedly arranged inside the housing. The housing is provided with a clamping groove and a convex groove. The surface of the housing is provided with a number of equally spaced square openings, and the side of the housing is provided with a fitting groove.

[0006] Further, the length of the sleeve is less than the length of the housing.

[0007] Further, the sleeves are arranged in pairs, and the opening directions of the two sleeves in a pair are the same.

[0008] Further, both ends of the housing protrude to form limiting parts.

[0009] Further, a positioning groove is arranged inside the sleeve.

[0010] Further, an outer sleeve is sleeved outside the sleeve.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: for the LC-type modular fiber optic adapter of the present utility model, by setting the clamping groove and the convex groove, the connection between the adapter and other fiber optic devices is more stable and not easily detached. In addition, the limiting function can be achieved by setting the square openings, and the loosening of the fiber optic adapter is further prevented by setting the fitting groove, greatly improving the stability and firmness of the fiber optic adapter.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Such as Figure 1 and Figure 2As shown, the LC-type modular fiber optic adapter includes a housing 1 and a ferrule 7. The ferrule 7 is fixedly arranged inside the housing 1. The housing 1 is provided with a clamping groove 2 and a convex groove 3. The surface of the housing 1 is provided with a number of equally spaced square openings 4. The side of the housing 1 is provided with a mating groove 5. The length of the ferrule 7 is less than the length of the housing 1, so that there is enough space for the ferrule 7 to be fixed inside the housing 1. At the same time, it also avoids the ferrule 7 being too long and causing excessive contact with the external environment, thereby reducing the possibility of fiber optic signal attenuation caused by the influence of the external environment. The ferrules 7 are arranged in pairs, and the opening directions of the two paired ferrules 7 are the same, so that the fiber optic adapter can support the connection of two fiber optic lines at the same time, improving the use efficiency of the fiber optic adapter. At the same time, it also reduces the cost caused by the need for multiple adapters for fiber optic connection. The two ends of the housing 1 protrude to form a limiting part 6, so that the adapter can be better fixed to other devices or panels during installation, enhancing the stability of the adapter and avoiding the adapter falling off or shifting due to vibration or external force. The inside of the ferrule 7 is provided with a positioning groove 8, so that the optical fiber can be better positioned when inserted into the ferrule 7, improving the accuracy and stability of the fiber optic connection. At the same time, the design of the positioning groove 8 also helps to reduce the friction of the optical fiber inside the ferrule 7 and reduce the risk of optical fiber damage. The outside of the ferrule 7 is sleeved with an outer sleeve 9, and the outer sleeve 9 can be used to protect the ferrule 7.

[0018] In the LC-type modular fiber optic adapter of this embodiment, by setting the clamping groove 2 and the convex groove 3, the connection between the adapter and other fiber optic devices is more stable and not easy to fall off. In addition, by setting the square opening 4, the limiting function can be realized, greatly improving the stability and firmness of the fiber optic adapter.
