Description

Technical Field

[0001] This utility model relates to the field of optical fiber splitting technology, specifically a sealed and waterproof optical cable splitting box. Background Technology

[0002] Optical fiber, short for optical waveguide fiber, is a type of fiber made of glass or plastic that serves as a means of transmitting light. The transmission principle is "total internal reflection of light." Today, optical fiber is increasingly widely used as a data transmission line. In optical fiber cabling, one or more main optical cables are often used, and then each main cable is split into several individual fibers using a fiber splitter.

[0003] In outdoor fiber optic splitting, fiber splitting boxes are often used for the splitting operation. Since the fiber splitting boxes are set outdoors, outdoor moisture and dust often cause damage to the internal components of the fiber splitting boxes, affecting the service life of the fiber splitting boxes and making it difficult to meet the user's needs.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 4 The present invention provides the following technical solution:

[0021] A sealed and waterproof optical cable distribution box includes an outer cabinet and an inner cabinet. The inner cabinet is fixedly installed inside the outer cabinet, and the outer side wall of the inner cabinet is separate from the inner side wall of the outer cabinet, forming a double-box structure, thereby enhancing the sealing, dustproof and waterproof effect.

[0022] The outer cabinet includes an outer cabinet 1 and an outer cabinet door 2. The outer cabinet door 2 is hinged to the outer cabinet 1. The inner box is installed inside the outer cabinet 1. The outer cabinet door 2 is used to open and close the outer cabinet 1, making it convenient for users to operate the inner box.

[0023] The inner enclosure includes an inner cabinet 5 and an inner cabinet door 6. The inner cabinet door 6 is hinged to the inner cabinet 5 and is used to open and close the inner cabinet 5. The top of the inner cabinet 5 is fixedly connected to the inner top wall of the outer cabinet 1, so that the four sides of the inner cabinet 5 are separated from the inner side walls of the outer cabinet 1, effectively reducing the flow of water and dust into the inner cabinet 5 from the outer cabinet 1. The bottom of the inner cabinet 5 is separated from the bottom of the outer cabinet 1. Several cable inlet holes 8 and cable outlet holes 9 are evenly provided on the bottom of the inner cabinet 5 to facilitate cable entry and exit. Sealing mechanisms are installed at both the cable inlet holes 8 and the cable outlet holes 9 to seal the gaps between the optical cable / fiber and the holes. The sealing mechanism is a sealing post 11, which is adapted to the inlet hole 8 or the outlet hole 9. The size of the inlet post can be set according to the hole diameter. A limiting pad 10 is provided on the top of the sealing post 11. The limiting pad 10 plays a limiting role and reduces the possibility of the sealing post 11 falling off the hole. A sleeve hole 12 is opened in the middle of the sealing post 11 and the limiting pad 10, which is used to accommodate the optical cable and optical fiber. A notch 13 is opened on the outer side wall of the sealing post 11 and the limiting pad 10 along its axial direction. The notch 13 extends to the sleeve hole 12, so that the sealing post 11 can wrap the optical cable and optical fiber in the sleeve hole 12 through the notch 13.

[0024] The sealing column 11 and the limiting pad 10 are integrally formed. The sealing column 11 and the limiting pad 10 are made of rubber, sponge or silicone material, which makes the sealing column 11 have good sealing performance and a certain degree of elasticity, so that the sealing column 11 can fit tightly with the inlet hole 8 and the outlet hole 9.

[0025] The inner cabinet 5 is equipped with mounting rails 7, and fiber splitters, fiber split boxes, or other related equipment are installed on the mounting rails 7.

[0026] Several wiring channels 3 are provided on the lower part of both sides of the outer cabinet 1. The wiring channels 3 are used for the entry and exit of optical cables and optical fibers at the outer cabinet 1. A water baffle 4 is installed above the wiring channels 3 to reduce rainwater from entering the outer cabinet 1 through the wiring channels 3.

[0027] The specific implementation process is as follows:

[0028] When using this sealed waterproof optical cable distribution box to split optical cables, the optical cable and the splitting fiber enter the outer cabinet 1 from the wiring groove 3 on the side of the outer cabinet 1, and then pass through the inlet hole 8 and outlet hole 9 at the bottom of the inner cabinet 5 into the inner cabinet 5. The optical cable and fiber can then be plugged into the splitter and distribution box in the inner cabinet 5. Then, through the matching sealing post 11, the optical cable and fiber are wrapped in the sleeve hole 12 inside the sealing post 11 through the notch 13 on the side of the sealing post 11. Finally, the sealing post 11 is installed at the inlet hole 8 and outlet hole 9 to complete the splicing and installation of the optical cable and fiber.

[0029] This sealed and waterproof optical cable distribution box has a double-cabinet structure consisting of an outer cabinet 1 and an inner cabinet 5. The corresponding splitters and fiber distribution boxes are installed in the inner cabinet 5. At the same time, sealing posts 11 are installed at the inlet hole 8 and outlet hole 9 at the bottom of the inner cabinet 5 to wrap the inlet and outlet lines of the optical cable and optical fiber, thereby sealing the gaps between the inlet hole 8, outlet hole 9 and the optical fiber. This effectively seals the inner cabinet 5, reducing the damage of water, dust and other pollutants in the external environment to the splitters and other equipment inside the inner cabinet 5, and improving the service life of the optical fiber and splitters.
