specific Embodiment 1

[0020] see Figure 1-2 , the present invention provides a technical solution: a waterproof and sealed optical cable splice box, comprising a box body 1 and a box cover 2, the top ends of the side walls of the box body 1 and the box cover 2 are uniformly extended outwards with an installation part 3, the Both sides of the box body 1 and the box cover 2 are uniformly provided with an access part 4 that can lead into the optical cable in the joint box. The access part 4 is provided with an access channel 13. At the same time, gravity is used to cause the water to flow downward According to the principle of flow, the present embodiment adopts that the access part 4 is inclined downward toward the box body, and the side walls of the box body 1 and the box cover 2 are composed of an outer layer wall 5 and an inner layer wall 6, wherein the outer layer wall The heights of the layer wall 5 and the inner layer wall 6 are inconsistent, the inside of the outer layer wall 5 is a cavity, a...

specific Embodiment 2

[0023] Such as image 3 As shown, on the basis of the specific embodiment 1, the inside of the inner wall 5 is a drying chamber 11, and a drying member 7 is also arranged in the drying chamber 11, and the inner wall of the inner wall 6 is provided with a The through holes 12 connected to the drying chamber 11 ensure the dryness in the optical cable splice box. The drying member 7 is a desiccant, and the desiccant in this embodiment is green, environmentally friendly, and has high material safety. A silica gel desiccant that does not produce overreactions, such as explosions, afterward, and can be reused after drying.

Abstract

The invention discloses a waterproof and sealed optical cable splice box, which comprises a box body and a box cover. The side walls of the box body and the box cover are both composed of an outer wall and an inner wall. The heights are inconsistent, the present invention adopts the side wall structure composed of the inner wall and the outer wall with different heights, which can achieve the sealing effect of the box body and the box cover. It enters the inner cavity through the drying hole at the first time and is absorbed and dried by the drying parts, which greatly reduces the possibility of water seeping into the inner wall and achieves an effective waterproof effect; The occlusal structure can ensure that the seals between the inner walls can be tightly occluded under the action of elastic force, so as to achieve an effective sealing effect. In addition, the double-layer side wall structure can ensure the quality of the optical cable splice box and reduce the cost of the cable splice box. damaged.

Description

technical field [0001] The invention relates to the technical field of optical fiber equipment, in particular to a waterproof and sealed optical cable joint box. Background technique [0002] The optical cable splice box is an important component in the optical cable line, which plays an important role in protecting the optical fiber connection of the optical cable and the communication transmission of the optical cable line. [0003] The most common failure of the optical cable splice box is poor sealing. After being exposed to moisture or water, the performance of the optical fiber will gradually deteriorate, causing communication failures, especially the horizontal optical cable splice box. Fixed and sealed, the operation is not easy enough, and the sealing effect is not ideal enough, once the bolts are loose, it will cause sealing problems. Contents of the invention [0004] The object of the present invention is to provide a waterproof and sealed optical cable splice...
