The portable light cable distributing box
Technical field
The utility model relates to a kind of portable light cable distributing box, belongs to the fiber optic communications equipment technical field.
Background technology
Fiber to the home also will become a kind of final form of Optical Access Network development along with the continuous development of the communication technology.And the optical fiber distributing cabinet is the connection device of optical cable and optical communication equipment, has the fixing functions such as protection with protection, optical fiber terminating, line transfer and tail optical fiber of optical cable.But existing optical fiber distributing cabinet is based on framed structure, and each functional unit plate is installed on the distributing frame of rack, carries out fused fiber splice and wire jumper etc. and safeguards or install, and realizes the handing-over of optical fiber.But the distribution cabinet volume is bigger, can not move, and therefore can not be installed in outdoor or the narrow and small occasion in more indoor spaces.
Summary of the invention
The purpose of this utility model provides a kind of dustproof, good water-proof effect that has, and is convenient for carrying and fitting operation portable light cable distributing box easily.
The utility model is that the technical scheme that achieves the above object is: a kind of portable light cable distributing box, it is characterized in that: comprise casing and case lid that a side is hinged mutually, the case mouth of receiving in the periphery of described casing opening end has, the periphery of case lid is arranged on the outside of case mouth, and the O-ring seal that is installed on the case lid top inner wall is fitted in case mouth end face; The casing middle part is equipped with vertical adapter stent, and casing is divided into welding area and jumping fiber memory block, and adapter is inserted on the mount pad of adapter stent; Casing is positioned at back cable screwed union is installed on the line hole of welding area one side, and casing is positioned on the madial wall of line hole one side the optical cable holder is installed, and fusion joining disk and terminal are installed in the welding area of casing; In the jumping fiber memory block of casing fiber storage tray is installed, on the optical fiber hole of casing jumping fiber memory block one side the cable screwed union is installed.
The utility model portable light cable distributing box combines in one movably in the casing with fixedly protection of optical cable, fused fiber splice, optical patchcord and optical fiber storage more than needed; especially the center section of casing is provided with adapter stent; adapter can be installed in the medium position of casing; so side welding area of adapter; opposite side then is the jumping fiber memory block; not only make things convenient for fitting operation, also be convenient to follow-up Operation and Maintenance.The utility model adopts the body structure that volume is less, be convenient for carrying, and can realize fiber direct connection, cross connection and straight molten function in case, can be in the space narrow and small indoor or outdoors realize the handing-over of optical fiber.Cross-connecting box of the present utility model adopts casing and the cover structure that is hinged, because of the case mouth of casing opening end is the case mouth structure of interior receipts, the periphery of case lid is arranged on the outside of case mouth, and by O-ring seal and box sealing, makes cross-connecting box reach the seal request of the dustproof and waterproof of IP55 level.
