Description

Technical Field

[0001] The utility model mainly relates to the field of optical fiber distribution boxes, and particularly relates to an optical fiber distribution box for real-time monitoring of the state of secondary cables. Background Art

[0002] An optical fiber is the abbreviation of an optical fiber waveguide, which is a fiber made of glass or plastic and can be used as an optical conduction tool. The transmission principle is "total internal reflection of light";

[0003] The optical fiber distribution box is suitable for the distribution connection of optical cables and optical communication equipment. Through the adapters in the distribution box, optical jumpers are used to lead out optical signals to achieve the optical distribution function. It is suitable for the protective connection of optical cables and distribution pigtails, and is also suitable for use at the optical fiber terminal points in the optical fiber access network.

[0004] The inventor found the following defects during the operation of specific embodiments:

[0005] However, a certain length of optical fiber needs to be reserved inside the optical fiber distribution box for subsequent replacement. However, when the optical fiber is directly placed inside the optical fiber distribution box, since the optical fiber is bent, it is easy to cause the optical fiber inside the optical fiber distribution box to break, making the optical fiber unable to conduct information.

[0006] It should be noted that the above content belongs to the technical cognition scope of the inventor. Due to the vast and complex technical content in this field, the above content of this application does not necessarily constitute the prior art. Content of the Utility Model

A slider is arranged at the bottom of the moving ring, a return spring is arranged between the slider and the guiding groove, and fitting grooves are provided on the outer walls of the fixed ring and the moving ring;

[0012] Install the optical fiber inside the distribution box housing, and then wind the excess optical fiber between the fixed ring and the moving ring. The return spring can push the moving ring to move outward. The arc-shaped fixed ring and moving ring can prevent the optical fiber from being bent during placement.

[0013] Furthermore, a fiber optic fixing structure is provided at the top of the distribution box housing, and the fiber optic fixing structure is connected to the distribution box housing by bolts.

[0014] Furthermore, the fiber optic fixing structure includes a door panel. The door panel is arranged on the outer wall of the distribution box housing. A positioning strip is arranged on the inner side of the door panel. The outer wall of the positioning strip fits with the inner wall of the positioning groove. An auxiliary groove is arranged at one end of the positioning strip.

[0015] Furthermore, a support shaft is arranged at the bottom of the inner wall of the distribution box housing, and a clamping ring is arranged at the top of the support shaft. The clamping ring is arc-shaped.

[0016] Furthermore, the number of the clamping rings is set to be multiple, and the multiple clamping rings are evenly distributed inside the distribution box housing.

[0017] Furthermore, a cooling pipe is arranged inside the distribution box housing. One side of the cooling pipe is arranged inside the vertical plate. A support plate is arranged on the outer wall of the distribution box housing. A heat dissipation fan is arranged inside the support plate.

[0018] 3. Beneficial effects:

[0019] Adopting the technical solution provided by the present utility model, compared with the prior art, it has the following beneficial effects:

[0020] In the present utility model, the reserved wire is wound between the fixed ring and the moving ring, and then the return spring drives the slider to move. The slider drives the moving ring to move away from the fixed ring, so as to fix the optical fiber inside the fitting groove and pull the optical fiber. The arc-shaped fixed ring and moving ring can prevent the optical fiber from being bent, resulting in fiber breakage and affecting signal transmission;

[0021] After the optical fiber is installed inside the distribution box, it is also necessary to perform secondary real-time status monitoring on the temperature of the optical fiber to avoid overheating inside the optical fiber. When the temperature monitor detects that the temperature of the optical fiber inside the vertical plate is too high, the heat dissipation fan is started. The heat dissipation fan cools the coolant inside the cooling pipe, and the heat of the optical fiber is discharged through the cooling pipe. Description of the drawings
