[0001] The utility model relates to the technical field of optical fiber terminal boxes, in particular to a port protection structure of an optical fiber terminal box. Background Art

[0002] The fiber optic terminal box is the end connector of an optical cable. One end of it is the optical cable and the other end is the pigtail. It is equivalent to a device that splits an optical cable into single optical fibers. The user optical cable terminal box installed on the wall has the function of providing fiber-to-fiber fusion splicing, fiber-to-pigtail fusion splicing, and optical connector connection.

[0003] Fiber optic terminal boxes are a type of equipment that is widely used and common nowadays. With the continuous development of society, people's requirements for the use of fiber optic terminal boxes are becoming more and more extensive.

[0029] The inner wall of the shaft hole 13 is movably connected with the rotating shaft 11, the outer wall of the rotating shaft 11 is movably connected with the shaft sleeve 10, the outer wall of the shaft sleeve 10 is fixedly connected with the protective plate 12, the front of the protective plate 12 is fixedly connected with the handle frame 3, the front of the protective plate 12 is fixedly connected with the retaining frame 4, the back of the retaining frame 4 is fixedly connected with the retaining plate 15, and a retaining hole 14 is provided on the front of the protective outer cover 8. During the use of the optical fiber terminal box, each port can be individually protected from dust, avoiding the port from being directly exposed to the outside when not in use and easily accumulating dust and stains, thereby avoiding the dust from having a bad influence on the connection work of the port, and further improving the stability of the use of the optical fiber terminal box.

[0030] In this embodiment, the shape and size of the retaining plate 15 match those of the retaining hole 14 , and the retaining plate 15 is snap-fitted to the retaining hole 14 , so that the port body 16 can be shielded from dust by fixing the position of the protective plate 12 .

[0031] Example 2

[0032] On the basis of Example 1, the preferred embodiment of the optical fiber terminal box port protection structure provided by the present invention is as follows: Figures 1 to 5 As shown: a mounting plate 6 is fixedly connected to one side of the protective cover 8, and a bolt hole 17 and a bolt slot 7 are respectively provided on the front of the mounting plate 6 and the front of the protective cover 8, and the inner walls of the bolt hole 17 and the bolt slot 7 are removable with bolts 5, which can facilitate the installation and disassembly of the terminal box body 1 and the protective cover 8, so as to facilitate the later maintenance of the terminal box body 1 and the replacement of the protective cover 8.

[0033] In this embodiment, the shape and size of the terminal box body 1 and the partition 2 combination match the shape and size of the protection plate 12, and the protection plate 12 and the protection cover 8 are respectively a transparent protection plate and a transparent protection cover, so as to facilitate the separate protection of each port body 16 from dust.

[0034] Furthermore, the port body 16 is located inside the protective cover 8 , and there are eight partitions 2 , which are arranged at equal distances inside the protective cover 8 , so as to divide the inside of the protective cover 8 into multiple spaces.
