The invention discloses an injection molding optical structure based on an optical fiber coupling module and belongs to the technical field of optical fiber coupling modules. The structure comprises acoupling module body, wherein a buckle is arranged on an upper surface of the coupling module body, a baffle plate is clamped on an outer surface of the coupling module body, and the baffle plate isU-shaped. According to an injection molding optical structure based on an optical fiber coupling module, a sealing rubber plate and a sealing plate are arranged, the metal is not easy to contact withthe outside air, the optical fiber coupling module is not easy to check and receive energy heat due to an internal metal structure, the situation that, due to the fact that local heat is too high andmakes contact with outside air, the air temperature difference is too large, and water vapor is condensed occurs, water vapor caused by excessive temperature difference and contact between the interior of the coupling module body and the outside is effectively reduced, so short circuit is formed in the optical fiber coupler due to excessive moisture or water inflow, the service life of the coupling module body is effectively guaranteed, and possibility of optical fiber short circuit damage is reduced.
Description
technical field [0001] The invention belongs to the technical field of optical fiber coupling modules, in particular to an injection molding optical structure based on optical fiber coupling modules. Background technique [0002] Optical fiber couplers, also known as splitters, connectors, optical fiber flanges and other fields, are components used to realize optical signal splitting or combining, or to extend optical fiber links. They belong to the field of optical passive components and are used in telecommunication networks , cable television network, user loop system, local area network will be applied, in the production of fiber optic coupler is usually made by high temperature melting and injection molding, at present, the fiber coupling composed of input fiber and output fiber A certain amount of light leakage will occur in the coupler cone. This part of the light leakage will generate local heat in the encapsulated metal structure. With the accumulation of local heat...
