Description

Technical Field

[0001] The invention belongs to the technical field of optical fiber connectors, and in particular relates to an MT connector. Background Art

[0002] The MT connector is a multi-core fiber optic connector suitable for high-density fiber optic transmission with small installation space and a large number of optical paths. It is generally used for internal connections in optical transceiver equipment such as data centers and splitters in high-density environments. One MT connector can transmit up to 72 optical fibers at the same time. The MT ferrule is a key component that determines the connection characteristics of the fiber optic connector and is usually injection molded from PPS material. With the development of fiber optic communications and data centers, high-speed optical communication modules are the main components of data centers and optical communication networks, and MT ferrules and optical fibers are often used in high-speed optical communication modules as the same-density connection components, so the demand for MT ferrules has also increased. Conventional MT ferrules have a rectangular structure. After the MT ferrules go through processing procedures such as fiber threading, glue dispensing, curing, grinding and testing, the MT ferrules are precisely positioned and docked using guide pins to achieve high-precision optical signal transmission requirements.

[0003] Chinese patent document CN220340446U discloses an MT-MT optical fiber connector, including an MT ferrule and a housing, wherein the upper surface of the housing is provided with a through receiving groove, wherein the MT ferrule is installed in the receiving groove, and the plug-in ends at both ends of the MT ferrule are passed through the receiving groove, and a locking ring is installed in the housing, wherein the locking ring clamps the MT ferrule, and the MT ferrule is fixed relative to the housing. The beneficial effects are: MT quick docking can be achieved, assembly and disassembly are convenient, and miniaturization is achieved, and the lower housing and the locking ring can be directly used for communication testing in a stable environment; in a harsh environment, the upper housing and screws can be used to completely fix it, thereby ensuring the reliability of the use of the MT-MT optical fiber connector.

[0004] The MT ferrule in the above patent document needs to be fixed by 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 volume of the entire connector to be too large. A connector that is too large is not suitable for use in a narrow space environment and has certain limitations. Summary of the invention
