Detailed ways

The embodiments of the present utility model are described in detail below in conjunction with the accompanying drawings; it should be noted that the present embodiments are descriptive, not restrictive, and cannot limit the protection scope of the present utility model with this. the

A new type of optical fiber wiring box based on the layout of optical fiber construction in intelligent substations. Its innovative point is that it includes a box body 2. In order to keep it beautiful and tidy and prevent foreign objects from entering the box body, a box cover 1 is installed on the box body through screws. the

An optical fiber inlet is made at the bottom of the box body, and a base plate is not installed at the bottom of the box body usually, so an optical fiber inlet can be formed; a group of optical fiber outlets 3 are made on one of the side plates of the box body. A group of winding posts 4 are installed on the inner sidewall of the box body backboard by a plastic sleeve, and the winding posts and the fiber outlets are arranged vertically, and the numbers of the winding posts and the fiber outlets are the same. the

The wire baffle can be made integrally with the winding post, or can be installed on the winding post in other ways. the

The working principle of the utility model is:

The optical fiber required by the device in the screen cabinet enters the screen body and directly enters the fiber arrangement box. By analyzing the equipment to be connected to the optical fiber, select the nearest winding column for fiber winding, and bend and guide the overlong optical fiber on the winding column to reach Natural bending effect, and then lead out the optical fiber through the fiber guide groove on the side of the fiber optic wiring box (that is, the fiber outlet) to connect to the protection measurement and control device. The box cover is installed on the outside of the fiber winding box through screws and nuts to cover the fiber wiring box. . The overall installation of the fiber optic wiring box should consider the characteristics of the main frame of the screen cabinet. The selection of the installation side cannot affect the main frame of the entire screen cabinet, and some terminal blocks are reserved for the power supply of the device. the
