Description
Technical field
The utility model relates to mobile communication technology field, and particularly relating to one can repeat open cable connector box.
Background technology
At present, cable splice closure is widely used in optical network communication construction, is applicable to make somebody a mere figurehead, direct-burried, pipeline (tunnel) install, have and recover the integrality of cable jacket and the function of cable strength members; The function of the electrical communication of hardware in optical cable, ground connection or disconnection is provided; There is the performance making fibre-optical splice from environmental impact; The function with remaining fiber optic storage of laying of fibre-optical splice is provided.Therefore, the leakproofness of connector box is just very important for whole optical-fiber network, if connector box water inlet, then and will certainly the security performance of extreme influence optical network communication.
All the time, on market, most connector box all adopts unvulcanized rubber as encapsulant, though favorable sealing property after encapsulation, repeats unlatching very inconvenient, if and connector box open after carry out second time encapsulate also to change sealing strip, use very inconvenient.Have some can accomplish the connector box repeating to open in the market, and second time encapsulation does not need to change sealing strip yet, but sealing effectiveness is not good enough, can not be stable be tested by industry standard yet.
Utility model content
The technical matters that the utility model mainly solves is to provide one can repeat open cable connector box, good airproof performance, can repeat to open to use.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide one to repeat open cable connector box, comprise: upper cover, lower cover and elastic body sealing strip, described elastic body sealing strip offers the first seal face, second seal face, 3rd seal face, 4th seal face and locating slot, the edge of opening of described upper cover arranges the ring compression groove that a cross section is " convex " font, the edge of opening of described lower cover arranges an annular guide collar, the inner side and outer side of described annular guide collar offers an emptying groove respectively, the locating slot of described elastic body sealing strip is enclosed within the annular guide collar of lower cover, the ring compression groove of described upper cover is pressed on elastic body sealing strip, by multiple screw fastening between upper cover and lower cover.
In the utility model preferred embodiment, the optical cable insert port of described lower cover rear and front end is respectively arranged with elastic body tightening ring, plug, back-up ring and check nut from the inside to the outside.
In the utility model preferred embodiment, described elastic body tightening ring is built in optical cable insert port, and described plug and back-up ring are built in check nut, and described check nut is locked with optical cable insert port and is connected.The beneficial effects of the utility model are: its upper cover of the utility model is with adopting integrated elastic body sealing strip between lower cover, and adopt multiple screw fastening, sealing strip adopts " labyrinth type " design, amounts to airtight of four roads, ensure that its multi-sealed performance and can repeat open-type function.
