Corresponding lock pin of laser fiber and cooperation mounting structure and fiber connector thereof

TLDR: In this paper, the lock pin entry of this laser fiber connector is the funnel pattern, and lockpin entry terminal surface sets up bell mouth and inside axle center passageway intercommunication promptly, the part that the axle center Passageway is close to the bell mouth satisfies the tight fit with the laser fiber who treats the installation location.

Abstract: The utility model provides a corresponding lock pin of laser fiber and cooperation mounting structure and fiber connector thereof can greatly alleviate the heat accumulation, improves the validity of fiber optic coupling. The lock pin entry of this laser fiber connector is the funnel pattern, and lock pin entry terminal surface sets up bell mouth and inside axle center passageway intercommunication promptly, the part that the axle center passageway is close to the bell mouth satisfies the tight fit with the laser fiber who treats the installation location. The interior side surface of bell mouth had better satisfy the diffuse reflection condition. Like this, side surface in the bell mouth is beaten to the laser speckle, makes the energy be the index through the reflex action and descends (had better produce complete diffuse reflection, avoid light to assemble), greatly lighten the heat accumulation. When especially installing high power laser optic fibre, the terminal surface is close to the big terminal surface parallel and level of the big terminal surface inclusive AND bell mouth of bell mouth before the optic fibre, has avoided hot accumulation to the ablation of fiber end face, improves the validity of fiber optic coupling.
