Technical Field

[0001] The utility model relates to the technical field of communication equipment such as aerospace measurement and control transmission systems, and specifically is a coupled welded high-reliability coaxial collimator. Background Art

[0002] A collimator is an optical component used for input and output in fiber optic communications. The divergent light emitted from the optical fiber is converted into parallel light by a convex lens in front, so that the light can be coupled into the required device with maximum efficiency or easily receive the optical signal with maximum efficiency.

[0003] Therefore, the performance reliability of the collimator directly determines the quality of optical fiber communication. Especially when used in high temperature, high humidity, and complex vibration environments, a collimator with reliable performance is particularly necessary.

[0004] Therefore, it is necessary to provide a coupled welded high-reliability coaxial collimator to achieve the above-mentioned purpose. Utility Model Content

[0005] The purpose of the utility model is to provide a coupled welding type high-reliability coaxial collimator.

[0006] The technical solution is as follows:

[0007] A coupled welded high-reliability coaxial collimator comprises a collimator body, wherein the collimator body has a ferrule fixing area, and an upper fixing seat setting area and a lower fixing seat setting area are distributed on the upper and lower sides of the ferrule fixing area;

[0008] The lower fixing seat setting area is fixed by welding the lower fixing seat module, then the collimator core is inserted into the core fixing area, and the upper fixing seat module is welded and fixed in the upper fixing seat setting area. Through the upper and lower welding fixing seat structures, a coupled welded high-reliability coaxial collimator structure is formed.

[0009] Furthermore, the collimator body is in the shape of a circular cylinder.

[0010] Furthermore, the collimator ferrule is a ceramic ferrule.

[0011] Furthermore, the upper fixing seat module includes an upper fixing seat, on which a collimating lens for use with the collimator ferrule is provided.

[0012] Furthermore, there are welds for upper coupling welding between the upper fixing seat and the upper fixing seat setting area.

[0013] Furthermore, the lower fixing seat module includes a lower fixing seat, and an optical cable channel is provided on the lower fixing seat. The optical cable channel is used for the collimator ferrule to connect the optical cable to pass through.

[0014] Furthermore, there is a weld for lower coupling welding between the lower fixing seat and the lower fixing seat setting area.

[0015] Compared with the prior art, the utility model forms a coupled welded high-reliability coaxial collimator by welding two upper and lower fixing seat structures. BRIEF DESCRIPTION OF THE DRAWINGS
