Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: a single-end contact type replaceable multi-core optical fiber adapter comprises a plug shell 1, a connecting nut component 3 and a socket shell 6, wherein a base body 5 is arranged in an inner cavity of the plug shell 1, optical fiber inserting bodies 4 are movably inserted into the base body 5 through openings, the number of the openings is determined according to the number of the optical fiber inserting bodies 4, a plurality of optical fiber inserting bodies 4 are distributed in the base body 5, a ceramic sleeve array 2 matched with the optical fiber inserting bodies 4 is arranged in the inner cavity of the plug shell 1 and on one side of the base body 5, the working temperature range of the multi-path optical fiber adapter is-55 ℃ to +125 ℃, the multi-path optical fiber adapter can be arranged on a fixed end connector of equipment or a movable end connector of an optical fiber component, and the adapter can be designed in a series mode according to the number of contact type optical fiber connectors and non-contact type optical fiber connector optical fiber inserting bodies matched with two ends, the adapter has the advantages that the axial dimension is uniformly designed, the optical fiber insertion body of the adapter is designed in a universal mode, and the assembly and use requirements of adapters with different core numbers are met.

As an optional embodiment, one side on the surface of the ceramic bushing array 2 is provided with a pressing plate 7, the surface of the pressing plate 7 is provided with an opening matched with the optical fiber insertion body 4, one side on the surface of the pressing plate 7 is fixedly provided with a limit bolt 8, and the surface of the base body 5 is provided with a threaded connection groove 9 matched with the limit bolt 8, so that the multi-path optical fiber adapter is more flexible to install and use, can be integrally disassembled and replaced, and can also be used for replacing the optical fiber insertion body 4 independently, thereby providing convenience for later maintenance.
