Description

Technical Field

[0001] The utility model relates to the technical field of optical communication, in particular to an optical fiber array coupling component. Background Art

[0002] The optical fiber array coupling component is a communication component used to connect optical waveguides, control the propagation direction of light, and control the optical coupling between optical waveguides, between devices, and between optical waveguides and devices. When the optical fiber array coupling component is used for medium connection, the acrylic coating of the optical fiber is first stripped, and then the optical fiber is clamped between the V-groove and the glass cover plate, and the optical fiber is ensured to fall into the groove. After the optical fiber falls into place, low-viscosity UV glue is dripped on the uncovered V-groove. The UV glue is sucked on the optical fiber along the V-groove and penetrated from the optical fiber to the joint under the glass cover plate. After searching: Patent number CN221007916U is a kind of optical fiber array coupling component. The technical scheme includes: a base plate, a connecting tube, a placement groove, a connecting rod and a piston. The outer wall of the upper end of the base plate is provided with equidistant and parallel placement grooves. A connecting tube is installed at the lower end of the inner wall of the placement groove. A sealing gasket is fixed on one side of the inner wall of the connecting tube. A connecting rod is arranged inside the sealing gasket. A piston is installed on the outer wall of one end of the connecting rod. By arranging the connecting tube, the connecting rod and the piston, the effect of improving the glue injection efficiency is achieved, the space at the lower end of the optical fiber is filled, the glue is convenient for the glue to enter the lower end of the optical fiber, and the glue injection efficiency is guaranteed.

[0003] However, the above-mentioned optical fiber array coupling assembly still has some shortcomings. The glue is pumped to the lower end of the optical fiber by means of a connecting rod and a piston, but the glue is directly pumped into the connecting tube, resulting in less glue at the lower end of the optical fiber. At the same time, personnel are required to pull and extract, which makes the personnel more tired. At the same time, after the air is pumped, the connecting rod needs to be broken, which causes unnecessary waste of resources. Therefore, we propose an optical fiber array coupling assembly to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide an optical fiber array coupling component, which has an arc channel, a through hole and a connecting tube, and can draw the glue at the upper end of the communication optical fiber into the V-groove at the lower end of the communication optical fiber, so that the glue fills the space at the lower end of the communication optical fiber, and is convenient for connection with the exhaust pipe.
