Description

Technical Field

[0001] This utility model belongs to the field of optical fiber connector technology, and specifically relates to an MT ferrule. Background Technology

[0002] MT connectors are multi-core fiber optic connectors suitable for high-density fiber optic transmission in environments with limited installation space and a large number of optical paths. They are typically used in high-density environments such as data centers and optical splitters within optical transceiver equipment. A single MT connector can transmit up to 72 optical fibers simultaneously. The MT ferrule is a key component determining the connection characteristics of the fiber optic connector and is usually injection molded from PPS material. With the development of fiber optic communication and data centers, high-speed optical communication modules are the main components of data centers and optical communication networks. MT ferrules and optical fibers, as connection components of the same density, are also frequently used in high-speed optical communication modules, thus increasing the demand for MT ferrules. Conventional MT ferrules have a rectangular structure. After processing steps such as fiber threading, adhesive dispensing, curing, grinding, and testing, the MT ferrule is then precisely positioned and mated using guide pins to achieve high-precision optical signal transmission.

[0003] Chinese patent document CN220340446U discloses an MT-MT fiber optic connector, including an MT ferrule and a housing. The upper surface of the housing has a through-hole receiving groove, and the MT ferrule is installed in the receiving groove, with both ends of the MT ferrule extending out of the receiving groove. A locking ring is installed inside the housing, which locks the MT ferrule, fixing it relative to the housing. The advantages are: it enables quick MT mating, facilitates assembly and disassembly, and achieves miniaturization. In stable environments, communication testing can be performed directly using the lower housing and locking ring; in harsh environments, the upper housing and screws can be used to completely fix it, thus ensuring the reliability of the MT-MT fiber optic connector.

[0004] The MT ferrule in the aforementioned patent document needs to be fixed using components such as a housing and screws. Its overall fixing structure is relatively complex, and the housing will affect the heat dissipation of the MT ferrule. The housing will also cause the entire connector to be too large. A connector that is too large is not suitable for use in confined spaces and has certain limitations. Utility Model Content

[0022] like Figures 1-3 As shown, this embodiment provides an MT ferrule for use in an MT connector, which has two mating MT ferrules. The MT ferrule includes a ferrule body 1, on which a fixing slot 2 is provided. The number of fixing slots 2 can be set according to actual needs. The fixing slot 2 is used to engage a fixing member. One end of the fixing member is disposed in the fixing slot 2 of one ferrule body 1, and the other end of the fixing member is disposed in the fixing slot 2 of the other ferrule body 1, thereby keeping the two mating ferrule bodies 1 in a fixed state by the fixing member.

[0023] This utility model designs a fixing slot 2 on the ferrule body 1, and uses the fixing slot 2 to connect the fixing component, thereby realizing a stable connection between two mating ferrule bodies 1. It adopts a brand-new fixing method to fix the ferrule body 1. The fixing method of the ferrule body 1 is simple and reliable, the data transmission is stable, and there is no need to design a shell. It will not affect the heat dissipation of the ferrule body 1, and will not cause the MT connector to be too large. It can be used in narrow space environments and has a wide range of applications.

[0024] like Figure 3As shown, in one specific embodiment, the fixing member includes an annular fixing band 3, which is used to fit into the fixing grooves 2 of the two ferrule bodies 1 to keep the two mating ferrule bodies 1 in a fixed state. After the two ferrule bodies 1 are mated, the annular fixing band 3 is installed to stably connect the two ferrule bodies 1. Preferably, the annular fixing band 3 is an elastic band.

[0025] like Figure 3 As shown, to further improve the connection stability of the two ferrule bodies 1, each ferrule body 1 is provided with a fixing slot 2 on both sides, and each fixing slot 2 is provided with a corresponding annular fixing band 3. The two annular fixing bands 3 are arranged in parallel, and several reinforcing strips 4 are provided between the two annular fixing bands 3 to increase the stability of the annular fixing bands 3.

[0026] In one specific embodiment, the fixing component includes a fixing buckle, with hooks at both ends. The two hooks respectively engage in the fixing slots 2 of the two insert bodies 1, thus maintaining the two mating insert bodies 1 in a fixed state. Fixing slots 2 are provided on both sides of the insert body 1, and each fixing slot 2 corresponds to a fixing buckle. The hooks at the ends of the fixing buckles engage in the fixing slots 2 of the insert bodies 1, ensuring the connection stability of the insert bodies 1. It should be noted that the fixing component in this utility model is not limited to structures such as the annular fixing band 3 and the fixing buckle. Simple modifications made by those skilled in the art based on the inventive concept of this utility model are all within the protection scope of this utility model.

[0027] like Figure 1 As shown, in one specific embodiment, the ferrule body 1 has an optical fiber insertion surface and an optical fiber exit surface at both ends.

An optical fiber channel is provided inside the ferrule body 1, with both ends connected to the optical fiber insertion slot and the optical fiber jack 5, respectively. An adhesive injection port 7, communicating with the optical fiber channel, is formed on the surface of the ferrule body 1. Adhesive is injected into the optical fiber channel through the adhesive injection port 7 to fix the optical fiber. A positioning hole 6 or a guide pin is formed on the optical fiber exit surface, which facilitates the docking of two ferrule bodies 1. For two docking ferrule bodies 1, one ferrule body 1 has a positioning hole 6, and the other ferrule body 1 has a guide pin. The guide pin of one ferrule body 1 is inserted into the positioning hole 6 of the other ferrule body 1, allowing the two ferrule bodies 1 to dock smoothly and avoiding adverse consequences such as misalignment or incomplete contact.

[0028] like Figure 2As shown, in one specific embodiment, the ferrule body 1 includes a mating portion 8 and a boss portion 9. The width of the mating portion 8 is smaller than the width of the boss portion 9, and the fixing groove 2 is provided at the connection between the mating portion 8 and the boss portion 9. The boss portion 9 facilitates the user to pinch the ferrule body 1 with their fingers to assemble and disassemble the MT connector.

[0029] In use, the user pinches the protrusion 9 with their fingers, then aligns the two ferrule bodies 1, and finally secures them with the annular fixing strap 3, thus maintaining a stable connection. The ferrule bodies 1 of this invention have a simple structure, are fixed in place by fasteners, are easy to assemble and disassemble, have good fixing effect, provide stable data transmission, and reduce the size of the MT connector, allowing it to be used in confined spaces and improving space utilization.
