Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber coupler curing, in particular to a structure for curing an optical fiber coupler. Background Art

[0002] Fiber optic couplers, also known as splitters, connectors, adapters, and fiber optic flanges, are components used to split / combine optical signals or extend optical fiber links. They belong to the field of optical passive components and are used in telecommunication networks, cable TV networks, user loop systems, and local area networks. After the fiber optic coupler is installed on the optical fiber, glue needs to be applied to both ends of the fiber optic coupler, which is then cured by ultraviolet light to fix it on the optical fiber.

[0003] The existing Chinese patent announcement number is: CN220215572U, which discloses a device for curing a fiber optic coupler. After the fiber optic coupler is installed on the optical fiber, the fiber optic coupler is placed in the placement groove of the placement seat, and the optical fibers are placed in the limiting grooves on the fixed seat on the top of the bottom plate respectively. The screw rod is rotated by turning the hand wheel, and the screw rod rotates to move the pressure plate downward in the sliding groove. The downward movement of the pressure plate causes the pressure block to press the optical fiber to stabilize it. The pressure block is made of rubber material to prevent damage to the optical fiber. Subsequently, glue is applied to both ends of the block, so that the optical fiber can be stabilized during glue application to prevent the optical fiber from shifting, solving the problem that the optical fiber cannot be stabilized and the shift of the optical fiber will affect the effect of glue application. In this technical solution, when glueing and curing the fiber optic coupler and the optical fiber, only the optical fibers at both ends are fixed, and the fiber optic coupler is not fixed. Moreover, the optical fibers at both ends are fixed by separate structures, which may cause different forces on the optical fibers at both ends, and position shift is prone to occur, thereby affecting the effect of glue application and fixation. For this reason, we propose a structure for curing a fiber optic coupler. Utility Model Content
