Optical fiber coupler

Abstract

The invention discloses an optical fiber coupler, and relates to the technical field of optical fiber couplers, the optical fiber coupler comprises an optical fiber coupler body, two sides of the optical fiber coupler body are fixedly connected with mounting frames, the mounting frames are also provided with rat-proof mechanisms, each rat-proof mechanism comprises a box body, the box body is provided with a through cavity, and an optical fiber is inserted through the cavity; a plurality of movable bulges are arranged at the bottom of the cavity and are distributed in a rectangular array; a plurality of first air bags are positioned under the plurality of movable bulges; a plurality of first air bags are communicated with at least two second air bags; an exhaust channel is communicated withthe second air bags, and a piston plate and a connecting rod are arranged in the exhaust channel; a lower pressing plate is fixedly connected with the connecting rod, the lower pressing plate is located at the top of the cavity, and sharp conical teeth are densely distributed on the lower surface of the lower pressing plate; and an elastic lifting lug is arranged at the top of the cavity, and theelastic lifting lug is used for fixing the lower pressing plate.

Description

technical field [0001] The invention relates to the technical field of optical fiber couplers, in particular to an optical fiber coupler. Background technique [0002] Optical fiber couplers, also known as splitters, connectors, adapters, and fiber optic flanges, 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 widely used in telecommunication networks. , CATV network, user loop system, and local area network will be applied. [0003] At present, there are many types of fiber optic couplers on the market, and most fiber optic couplers are usually used indoors. If there are mice in the room, the fiber optic coupler is easily eaten by mice, resulting in poor fiber contact and broken settings. Therefore, it is an urgent need for those skilled in the art to design a fiber optic coupler that prevents mice from eating. Contents of the invention [0004] The obj...
