[0026] Example 1:
[0027] like figure 1 with figure 2 , The present embodiment shows a waterproof splice boxes, comprising an inner box and outer box 3, the cartridge 3 is mounted within the interior of the sleeve 1, the outer box 1 and the inner surface 3 is coated with a waterproof coating cartridge the outer box 1 is provided with a slit at the sealing strip, the sealing strip after swelling, the surface of the outer box 1 is provided for observing the inside of a window and the sleeve 1 is provided with sealing plates connected observation, the inner pack 1 is provided with desiccant, the desiccant after water absorption color.
[0028] This embodiment includes an outer box and an inner box 3, the inner surface of the sleeve 1 and the cartridge 3 is coated with a waterproof coating can reduce the residual moisture in the surface of the cartridge body 3 so that the sleeve 1 and the inner surface of the cartridge kept as dry as , thereby reducing the moisture into the interior of the sleeve 1, or the inner box 3, in the present embodiment further slits at the sleeve 1 is provided with a sealing strip, in the present embodiment the sealing strip is made of water absorbing resin obtained by the water-absorbing resin having a high water absorption capacity, it can absorb water hundreds to thousands of times more than their own weight, the further the water absorbing resin becomes hydrogel swelling, the water difficult to separate at this time, in the embodiment of the present embodiment 1 can be held inside the sleeve of said drying, improve the waterproof of the present embodiment, after the sealing strip can be further expanded occluder slit the sleeve 1 may reduce moisture into the interior of the sleeve 1, the sleeve 1 to improve the seal, protect the inner box 3, the inner surface of the cartridge 3 further coated with a waterproof coating is also possible to reduce residual moisture inside the sleeve 3 the inner surface of the case 1, reducing the moisture into the interior of the cartridge 3, to reduce the moisture Effect of the cable 2, and enhance the sealing performance of the waterproof embodiment.
[0029] Secondly, in the present embodiment, the sleeve is provided with an internal desiccant in the desiccant embodiment of the present embodiment is a color gel, silica gel after water absorption will change the color, and the color discoloration silica much variation absorbing moisture different embodiments therefore the present embodiment, the desiccant may be promptly absorb moisture inside the pack 1, reducing the moisture coming into the cartridge 3, the inner box 3 to reduce the influence of moisture inside the cable 2, improve the waterproof performance of the present embodiment, the 1 is provided with a window for observing the surface of the sleeve, the staff in the testing process can be observed through a desiccant pack inside the window, the worker is able to determine the number of desiccant pack degree of discoloration and discoloration desiccant moisture invading the internal number 1, to keep abreast of the situation inside the sleeve 1, workers can repair or replace the desiccant inside the actual situation, thereby improving the waterproof performance of the present embodiment.
[0030] Embodiment of the sleeve 1 of the present embodiment includes an upper casing 101 and lower casing 102, the outer box 1 with the upper casing 101 and lower casing 102 from the upper casing 101 and lower casing 102 are connected by a fastening means sealed upper surface of the window disposed on the housing 101, the upper casing 101 and is connected at the lower case 102 is provided with at least two through holes for connecting the optical fiber cable 2, is installed at the through hole wire barrel 4, the terminal 4 at the connection of the sleeve tube is provided with a sealing strip, can prevent outside moisture through the sealing strip by said terminal 4 at the connection of the sleeve tube 1 enters the interior of the sleeve 1, , thereby improving the waterproof performance of the present embodiment, followed by the expansion of the seal upon absorption of moisture, thereby sealing the gap between the wiring block 4 and the sleeve tube 1, further improve the sealing of the pack 1, can be to reduce the external moisture from entering the wiring from the connection tube 4 and the interior of the sleeve 1, to protect the internal optical fiber cable 2, thereby improving the service life of the cable 2.
[0031] In the present embodiment, when the sleeve 1 is provided with an internal groove 5 for receiving a desiccant receiving an end portion of the through hole is provided with receiving grooves 5, external moisture into the interior of the sleeve 1 through the connection tube 4, the desiccant receiving tank 5 will be able to absorb water in time, to prevent moisture remaining inside the sleeve 1, to reduce the effect of moisture on the cable 2, the cable 2 to protect and improve the life of the cable 2, the present embodiment to improve the waterproof performance, this further embodiment of the receiving groove 5 is provided in the cartridge 3 within four weeks, when the water inside the sleeve 3 near the inner box 1, the receiving groove 5 of the drying agent will absorb moisture in time, reducing moisture into the interior of the cartridge 3, the cable protection inside the inner box 32 from moisture influence and improve the life of the cable 2.
