The utility model discloses the beneficial effect of instance lies in: the problem of FTTH is under construction, concentrates and divides luminous point coverage area too big, and the construction is safeguarded inconveniently, and the construction cost is high is solved, this branching unit case is particularly suitable for the construction of rural FTTH.
Description
Technical field
This utility model relates to a kind of FTTH construction mixed type optical branching device box, and this shunt case mainly applies to, in FTTX network, belong to communication network device technical field.
Background technology
At present, FTTH builds light splitting of main employing and the construction mode of secondary light splitting, no matter use which kind of construction mode, it is required to set up to concentrate an optical splitting point, for outdoor optical cable being introduced and drawing, customer center at Relatively centralized arranges a fiber-dividing box or optical branching device box again, it is introduced to user for outdoor optical cable is converted into covered wire cable, it is the most suitable that this scheme is used in during the city FTTH comparatively concentrated builds, but in rural area FTTH builds, because country residents more disperses, as used above construction mode, be no matter the concentration optical splitting point of upper level or the fiber-dividing box of next stage or optical branching device box all to there is casing area coverage the biggest, safeguard inconvenient problem；And in cost of investment, at least need to build the cabinet equipment of 2 nodes, there is the problem that construction cost is high.
Summary of the invention
The technical problems to be solved in the utility model is: during rural area FTTH builds, no matter use and once divide or the construction mode of secondary light splitting, because country residents more disperses, as used traditional 24 core above shunt case or fiber-dividing boxes, there is area coverage big, the problem installing and safeguarding more inconvenience, and in the case of area coverage is big, need covered wire cable longer to user's length from casing, there is potential safety hazard；Increase as used the casing of the less core number of customization to there is again casing quantity, the problem that construction cost increases.
Deficiency for traditional product, this utility model provides a kind of mixed type optical branching device box, can be used for wall hanging to install or pole mounting means, front single open-door structure, insert type optical branching device is installed, meets the introducing of outdoor optical cable and covered wire cable simultaneously, closely use covered wire cable directly to lead to user in casing, remote employing outdoor optical cable extraction changes covered wire cable again into and is introduced to the mode of user, it is achieved the function of a casing multiple utilities；Welding fibroblast for outdoor optical cable and covered wire cable uses 12 cores to exempt from jumping fiber tail optical fiber and draws pallet, it is achieved exempt from the function of jumping fiber.
The technical scheme that this utility model offer is used is:
. a kind of mixed type optical branching device box, including casing, it is characterised in that described casing upper right is provided with optical cable welding device；Described casing upper left is provided with optical branching device fixed area, is used for fixing optical branching device；Described casing lower right is provided with optical cable fixing device；Described casing lower left is provided with tail optical fiber storage area.
Preferably, described optical cable fixing device includes rubber-covered wire cable fixing device, covered wire cable grounding device, outdoor optical cable fixing device, outdoor optical cable grounding device.
Preferably, described outdoor optical cable fixing device is larynx hoop, and described rubber-covered wire cable fixing device is adjustable briquetting.
Preferably, described optical cable welding device uses 12 cores to exempt from jumping fiber tail optical fiber pallet.
Preferably, described optical branching device uses insert type optical branching device.
Having the beneficial effects that of this utility model example: solve in FTTH construction, concentrates optical splitting point area coverage too big, construction maintenance inconvenience, the problem that construction cost is high, and this shunt case case is particularly suitable for rural area FTTH and builds.

Detailed description of the invention
The utility model is described in more detail with being embodied as example below in conjunction with the accompanying drawings.
The technical scheme is that casing of this utility model uses full-frontal mode of operation, fixing of fixing and 60 covered wire cables of maximum satisfied 2 outdoor optical cables, optical cable welding uses width 12 core to exempt from jumping fiber tail optical fiber and draws pallet, can meet the installation of 8 pallets, maximum can fibroblast subscriber optical cable 84 core；Using blade inserting shunt to install, maximum can meet the installation of 81 point 8 blade inserting shunts, or the installation of 41 point of 16 beam splitters, or the installation of 21 point of 32 beam splitters.
nullUtility model structural representation as shown in Figure 1，After casing is fixing on metope or telecommunications bar，Optical cable is introduced to optical cable bearing by casing (1-1)，Outdoor optical cable is fixed in optical cable fixing device (1-2) leftward position，Covered wire cable is fixed in optical cable fixing device (1-2) right positions，Optical cable circle pillar protection after fixation peeling is introduced to 12 cores of optical cable welding device (1-3) and exempts from welding in jumping fiber tail optical fiber extraction pallet，Insert type optical branching device is fixed at the optical branching device fixed area (1-4) of casing upper left，12 cores are exempted from the tail optical fiber of jumping fiber tail optical fiber extraction pallet and are entered to be introduced to extension tow wheel (1-6) place by the way of a left side goes out by wire loop (1-4) the employing right side，The tail optical fiber opened with optical branching device is needed upwards to terminate with optical branching device，The tail optical fiber that need not open is turned by extension tow wheel and is introduced to tail optical fiber memory block (1-7) storage.
In the case of user distance casing is close together, covered wire cable one end is used directly to register one's residence, the other end is introduced to welding in casing, the covered wire cable introducing casing passes rubber-covered wire cable fixing device (2-1) centre position by casing (1-1), the hand-screw stud utilizing rubber-covered wire cable fixing device (2-1) turns clockwise, tabletting activity downwards is pressed against optical cable, then will go up dead earth at covered wire cable grounding device (2-2) after strengthening core stripping as used outdoor version covered wire cable；In the case of user distance casing is distant, use outdoor optical cable to turn covered wire cable after drawing to register one's residence, then outdoor optical cable is introduced to outdoor optical cable fixing device (2-3) position larynx hoop is fixed by casing (1-1), and the strengthening core after stripping is at the upper dead earth of outdoor optical cable grounding device (2-4).
Although this utility model is open as above with preferred embodiment; but drawings and Examples are not for limiting this utility model; any it is familiar with this those skilled in the art; without departing from the spirit and scope of this utility model; from when can making various changes or retouch, all same within protection domain of the present utility model.Protection domain the most of the present utility model should be with being as the criterion that claims hereof protection domain is defined.
