Outdoor optical fiber connector and optical fiber adapter

Abstract

The invention discloses an outdoor optical fiber connector and an optical fiber adapter. The outdoor optical fiber connector comprises an SC internal part, an insertion core, an inner clamp, a circular hoop, a rotating shaft, an inner rod, an optical fiber, a protective cap, a pressing ring, a heat shrink tube and a tail sheath. The insertion core is installed in the SC internal part and the inner clamp, the inner clamp is installed in the circular hoop, and the inner clamp penetrates out of the circular hoop and is connected with the inner rod in the rotating shaft; a stripped optical fiber penetrates through the inner rod and then is connected in the insertion core, an annular positioning cylinder is arranged in the circular hoop, and an insertion cylinder is arranged at the end of the protective cap and used for being inserted between the outer wall of the circular hoop and the positioning cylinder. The optical fiber adapter comprises a main body seat, a ceramic sleeve, a U-shaped clamp, a nut and an end cap, when the optical fiber adapter is connected with the outdoor optical fiber connector, the front end of the main body seat is inserted into a circular hoop in the outdoor optical fiber connector, and an insertion core in the outdoor optical fiber connector is inserted into the ceramic sleeve of the optical fiber adapter.

Description

technical field [0001] The invention relates to the technical field of optical fiber connection, in particular to an outdoor optical fiber connector and an optical fiber adapter. Background technique [0002] Optical fiber connector is an indispensable optical communication connection component of Fiber To The Home (FTTH). It is mainly used in the "last mile" of FTTH fiber to the home, and is generally installed on optical communication distribution equipment near residential areas. [0003] At present, the most commonly used connection methods are: adapters, pigtails, and field-assembled fiber optic quick-connect components, which have poor waterproof performance and can only be used indoors, and are rarely used in outdoor environments. Due to poor waterproof performance, the above-mentioned optical fiber components can only be used inside the optical communication equipment; every time the construction is performed, the optical communication equipment must be opened, and t...

Problems solved by technology

[0003] At present, the most commonly used connection methods are: adapters, pigtails, and field-assembled fiber optic quick-connect components, which have poor waterproof performance and can only be used indoors, and are rarely used in outdoor environments.

Due to poor waterproof performance, the above-mentioned optical fiber components can only be used inside the optical communication equipment; every time the construction is performed, the optical communication equipment must be opened, and then the pigtails are inserted or the optical fiber quick-connect components are made on site to realize the termination of the optical fiber.

This not only prolongs the construction time, but also may affect the communication signals of customers who have already opened, and may also damage the internally constructed optical fibers.

At the same time, field-assembled optical fiber quick-connect components often require high quality construction personnel during on-site production. If the installation quality is not high, the optical signal will be greatly attenuated

Therefore, the existing optical fiber connection products cannot meet the requirements of single-person operation, rapid construction, plug and play, high quality and consistent quality for construction personnel
