Description

High-power laser connector

Technical Field

The utility model relates to the field of optical technology, concretely relates to high-power laser connector.

Background

The laser optical fiber connector is a device for making detachable connection between optical fibers, and it precisely butt-joints two end faces of optical fibers so as to maximally couple the light energy output by the transmitting optical fiber into the receiving optical fiber and minimize the influence on the system caused by the intervention of the laser optical fiber into the optical link, which is the basic requirement of the optical fiber connector. To some extent, fiber optic connectors affect the reliability and performance of optical transmission systems. Prior art makes in the high energy laser transmission process, and the heat accumulation brings the damage to connecting or even entire system, and the utility model discloses can customer service these problems completely. In the structure, the fixation of the optical fiber at the center of the receiving port depends on epoxy resin, and the heat resistance and corrosion resistance of the epoxy are poor; when high-power work is needed, the failure of epoxy can cause the failure of a joint, even the fixed range of a system damaged optical fiber is small, and when the fixed position is too concentrated to cause the use of subsequent products, the receiving end face of the optical fiber is easy to move, so that the coupling efficiency is reduced, and the risk of damage is caused.

Disclosure of Invention

The utility model provides a high-power laser connector, aiming at the problems, which comprises a ferrule front part, a ferrule rear part and a rear seat; internal threads are formed at the two ends of the rear part of the insert core; the rear seat is connected with the right side of the rear part of the insert core through internal and external threads; the front part of the insert core is connected with the left side of the rear part of the insert core through internal and external threads; the front part of the ferrule is internally provided with a plurality of through holes with different radiuses, and a conical surface is arranged between two adjacent holes on the left side of the front part of the ferrule.

Further, the outer diameters of the front portions of the ferrules are 3.172cm respectively.

Further, the ferrule rear portion has an outer diameter of 4.28 cm.

Further, the external thread diameter of the rear seat is 2.5 cm.

Furthermore, a quartz ring is fixed inside the right side of the front part of the ferrule.

The utility model has the advantages that: the center of the receiving port in the front of the ferrule is provided with a conical surface, so that when the ferrule works at high power, the heat resistance is enhanced, the corrosion resistance is improved, the damage of heat accumulation to a joint and even the whole system is reduced, and the fixation of an optical fiber is facilitated; the length of the inserting core is increased, so that the coaxiality during connection is improved, the moving displacement of the end face of the optical fiber is reduced, the coupling efficiency is increased, and the signal transmission is facilitated.
