    • A hermetically sealed fiber optic connector or feed through, the connector for connecting at least two fiber optic cables and including a center member having two extensions, with each of the extensions being cylindrical and coaxial. Each of the extensions includes a first engagement means and a first sealing means, with the center member defining a channel axially disposed relative to the extensions. A first connector includes a backshell, with the backshell including a second engagement means in complementary relationship with the first engagement means of a first one of the extensions, and a second sealing means in complimentary relationship with the first sealing means of the first one of the extensions. The first connector includes a ferrule seat and a ferrule joined to the ferrule seat, and includes a cylindrical crimp socket joined to the ferrule seat. The crimp socket defines an axial channel for receiving a first fiber optic cable. The ferrule seat defines a bore placing the ferrule in communication with the axial channel. The bore receives the optical fiber of the first fiber optic cable and places the ferrule in optical communication with the first optical fiber. The feed through of the present invention seals onto a fiber optic cable.
    • 密封的光纤连接器或馈通通孔,用于连接至少两根光纤电缆并包括具有两个延伸部分的中心部件的连接器,每个延伸部均为圆柱形和同轴的。 每个延伸部包括第一接合装置和第一密封装置,其中中心构件限定相对于延伸部轴向设置的通道。 第一连接器包括后壳,后壳包括与第一延伸部的第一接合装置互补关系的第二接合装置,以及与第一密封装置的第一密封装置互补关系的第二密封装置 扩展。 第一连接器包括套圈座和连接到套圈座的套圈,并且包括连接到套圈座的圆柱形压接插座。 压接插座限定用于接收第一光纤电缆的轴向通道。 套管座限定了将套圈与轴向通道连通的孔。 孔接收第一光纤电缆的光纤并使套圈与第一光纤光学通信。 本发明的进料通道密封在光缆上。
