Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber jumpers, in particular to a dustproof optical fiber jumper. Background Art

[0002] Fiber optic patch cords are used to connect equipment to fiber optic cabling links. They have a thicker protective layer and are generally used to connect optical terminals and terminal boxes. They are used in fiber optic communication systems, fiber optic access networks, fiber optic data transmission, and local area networks. Fiber optic patch cords can be divided into single-mode and multi-mode patch cords of common silicon-based optical fibers according to the transmission medium. In optical communications, single-mode and multi-mode refer to the different diameters of the glass core layer (called CORE in English) at the center of the optical fiber. When the fiber optic patch cord is not in use, the plugs at both ends are easily contaminated with dust, so a dust-proof structure needs to be set to address this problem.

The dustproof component arranged in the dustproof optical fiber jumper described in the utility model plays a role in protecting the optical fiber jumper head, and prevents the optical fiber jumper head from being directly exposed to the outside during storage and transportation.

[0004] The above patent still has the following shortcomings: the above patent uses a protective shell to protect the connector of the optical fiber jumper from dust. It is necessary to first use bolts to fix the installation component, and the protective shell is set on the dustproof component. During installation, it is necessary to press the limit block into the movable cavity, and then insert the rod into the slot to fix the limit block to complete the fixation of the protective shell. The whole operation method is relatively cumbersome. In daily use, it is not convenient to quickly disassemble and assemble the protective shell. In addition, after long-term use, the telescopic spring is repeatedly stretched and deformed, and its elastic force will be affected to a certain extent, which will affect the structure of the dustproof component, causing inconvenience in operation, and then affecting the stability of the protective shell.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a dust-proof optical fiber jumper is provided to achieve a purpose with greater practical value. Utility Model Content
