Abstract
The invention relates to a fiber outlet structure of a fiber distribution box. The fiber outlet structure is arranged on a box body of the fiber distribution box. The fiber outlet structure comprises a multi-group of fiber outlet assemblies which are arranged on a wall of the box body. Each group of the fiber outlet assembly comprises a downside cable inlet hole which is arranged on the wall of the box body and a plurality of fiber outlet holes. Removable sealing plugs are filled in the downside cable inlet hole and the fiber outlet holes. Because the sealing plugs are used to fill into the downside cable inlet hole and the fiber outlet holes, good seal can be achieved and influence of external environment on internal equipment during a usage process of the fiber distribution box can be avoided.
Description
Technical field
The present invention relates to a kind of communication facilities, specifically, relate to a kind of fiber-dividing box, especially its fiber mouth structure.
Background technology
Fiber-dividing box is that Fiber to the home (FTTH), the node product of emphasis in the Fiber-To-The-Node fields such as (FTTN), has functions such as optical cable welding, distribution.Often sealing is relatively poor for the fiber mouth structure of existing fiber-dividing box, in the process that it is installed and used, easily the equipment in the fiber-dividing box, optical cable etc. is impacted.
Summary of the invention
The fiber mouth structure that the purpose of this invention is to provide a kind of good sealing performance fiber-dividing box.
For achieving the above object, the technical scheme that the present invention adopts is:
A kind of fiber mouth structure of fiber-dividing box; Be arranged on the casing of fiber-dividing box; Described fiber mouth structure comprises the many groups fiber mouth assembly on the wall that is arranged at said casing; Every group of described fiber mouth assembly comprises that a descending optical cable on the wall that is opened in said casing advances cable hole and a plurality of optical fiber hole, and described descending optical cable advances in cable hole and the described optical fiber hole all that packing has dismountable sealing-plug.
Preferably, described descending optical cable enters the cable hole and described optical fiber hole connects as one through connecting path, and the sealing-plug that the described descending optical cable of packing advances cable hole and described optical fiber hole connects as one and described connecting path is sealed.
Preferably, described optical fiber hole is equally divided into two row and is distributed in equably on the wall of said casing, and described descending optical cable enters the central authorities that the cable hole is opened in an end of described two row optical fiber holes.
Preferably, every group of described fiber mouth assembly comprises 8 described optical fiber holes.
Preferably; Described descending optical cable advances the cable pore volume and receives an optical cable that is made up of some optical fiber and pass through; The fiber count that described optical cable comprises is identical with the number of the described optical fiber hole that every group of described fiber mouth assembly comprised, and each described optical fiber hole holds a described optical fiber to be passed through.
Preferably, has projection on the described sealing-plug.
Preferably, described fiber mouth structure also comprises the boss on the outer wall that is fixedly set in said casing, and described descending optical cable enters the cable hole, described optical fiber hole is opened on the described boss.
The present invention is divided into each branch after descending optical cable (being generally 8 core outdoor optical cables) inserts from descending optical cable advance the cable hole and snaps in the optical fiber hole in use, and untapped optical fiber hole is blocked with sealing-plug independently.If when running into descending optical cable and not exclusively using, the workmen can very clearly see the loading condition in this chest.
Because technique scheme utilization; The present invention compared with prior art has advantage: because the present invention adopts sealing-plug that descending optical cable is advanced cable hole and optical fiber hole sealing; Can reach good sealing, avoid fiber-dividing box in use external environment the equipment of its inside is exerted an influence.

Embodiment
Below in conjunction with embodiment shown in the drawings the present invention is further described.
Embodiment one: shown in accompanying drawing 1 to accompanying drawing 4.
A kind of fiber mouth structure of fiber-dividing box is arranged on the casing of fiber-dividing box.The casing of fiber-dividing box is made up of upper casing 1 and drain pan 2, and the fiber mouth structure is arranged on the lower wall of drain pan 2.
The outer setting of the lower wall of drain pan 2 has boss 3, and boss 3 edges have a small gap 9.The fiber mouth structure comprises the many groups fiber mouth assembly that is arranged on the boss 3, in the present embodiment, has 3 groups of these fiber mouth assemblies.Every group of fiber mouth assembly comprises that a descending optical cable that is opened on the boss 3 advances cable hole 4 and 8 optical fiber holes 5, and optical fiber hole 5 is equally divided into two row and is distributed in equably on the boss 3, and descending optical cable enters the central authorities that cable hole 4 is opened in an end of two row optical fiber holes 5.Descending optical cable enters cable hole 4 and connects as one through connecting path 6 with optical fiber hole 5; Descending optical cable advances cable hole 4, optical fiber hole 5 and connecting path 6 and is the distribution of " Gui " font; And descending optical cable enters the upper end that cable hole 4 is positioned at " Gui " word structure, and each optical fiber hole 5 is positioned at the left and right end of " Gui " word structure.Descending optical cable advances in cable hole 4 and the optical fiber hole 5 all that packing has dismountable sealing-plug 7, and the sealing-plug 7 that the descending optical cable of packing advances cable hole 4 and optical fiber hole 5 connects as one and with connecting path 6 sealings, sealing-plug 7 also is " Gui " font.
Descending optical cable enters cable hole 4 to be held an optical cable that is made up of some optical fiber and passes through, and the fiber count that optical cable comprises is identical with the number of the optical fiber hole 5 that every group of fiber mouth assembly comprised, and each optical fiber hole 5 holds an optical fiber to be passed through.
Have projection 8 on the sealing-plug 7 of integral type, can pass through its dismounting sealing-plug 7; When sealing-plug 7 is installed on descending optical cable when advancing in cable hole 4 and the optical fiber hole 5, projection 8 is stuck in the small gap 9 of boss 3.
