Background technology
Fiber cable cross connection box is a kind of interfacing equipment that is used for optical fiber Metropolitan Area Network (MAN) backbone optical cable and optical distribution cable node, can realize welding, dish storage and distribution, the scheduling of optical fiber.Open day by day along with telecommunication market, each runs the commercial city at the optical cable Metropolitan Area Network (MAN) that steps up to build oneself, and the Large scale construction of optical cable Metropolitan Area Network (MAN) can make the fiber cable cross connection box demand increase considerably.Existing fiber cable cross connection box generally all places on the ground, and its shortcoming is to influence the appearance of the city, influences traffic, the land occupation resource, and do not meet the requirement of modern city.And the structure in harmonious city, aesthetic measure requirement to the city city look and feel is higher, make the addressing of common outdoor fiber cable cross connection box difficult more, and outdoor fiber cable cross connection box causes artificial destruction easily, do not have early warning system when destruction or damage accident take place, even have a strong impact on optical fiber communication efficient.
The Minnesota ,USA mining industry is made joint-stock company (3M company) and has been proposed a kind of subterranean cable cross-connecting box; its principle is that common ground light cable distributing box is put into a guard box, again it is imbedded underground, when equipment needs repairing; guard box is risen to ground, carry out maintenance operation.The shortcoming of this fiber cable cross connection box is that maintenance is inconvenient, does not have accident pre-alarming system, in a single day when therefore being damaged accident, maintenance lasts longer.And message capacity is little, can not practical requirement.
Summary of the invention
The objective of the invention is to propose a kind of ground imbedded high-capacity optical cable connection box, the structure of existing fiber cable cross connection box is made improvements,, and enlarge the message capacity of cross-connecting box so that cross-connecting box is convenient to safeguard.
The ground imbedded high-capacity optical cable connection box that the present invention proposes, comprise casing and sealing case lid, be provided with into cable mouth in the casing, the optical cable chute, the fixing card of optical cable strengthening core, the fixing card of optical cable, lead fine groove, fibre melting disc, the fine bucket of wire jumper dish, scalable scrunching a little and emergent osculum, describedly advance the cable mouth, fixing card of optical cable strengthening core and the fixing card of optical cable lay respectively on the casing upper portion side wall, described optical cable chute is positioned at around the casing top on the wall, described fibre melting disc is positioned on two relative sidewalls of casing, describedly lead fine groove and be connected between fixing card of optical cable strengthening core and the fibre melting disc, the fine bucket of wire jumper dish places a side of fibre melting disc, scalable scrunching on the sidewall that a little places casing, emergent osculum is positioned at the lower curtate of casing.
The ground imbedded high-capacity optical cable connection box that the present invention proposes, its advantage is:
1, the cross-connecting box that proposes of the present invention is done as a wholely, can assemble in advance, then it is directly put into the hole of digging, the backfill soil cubic meter of stone, so easy construction is quick.Can utilize the vehicular traffic time few, that the people is few at night dig pit, backfill, therefore be easy to bustling location construction in the urban district, the optical cable in the cross-connecting box enters and welding etc. all is to carry out in the ground lower box, to not influence of traffic.
2, common outdoor fiber cable cross connection box takies resource on the ground, influences city look and feel, influences traffic, and cross-connecting box of the present invention is directly imbedded underground, effectively reduces the floor area of avenue, thereby can be widely used in bustling location, city, shopping centre or residential neighborhoods.
3, cross-connecting box of the present invention is imbedded undergroundly, can not cause pedestrian's attention, thereby avoid the artificial destruction to cross-connecting box, has guaranteed communication security.
4, in the cross-connecting box of the present invention, the workmen can directly enter operation in the case, is convenient to maintenance and installation to the optical cable handing-over.
5, cross-connecting box capacity of the present invention big (maximum can reach 2304 cores) can be used for convergence-level and optical cable turnover office that optical cable is relatively concentrated.
