Description
Technical field
The utility model relates to the connector box that a kind of aerial optical cable is used, particularly a kind of novel box type stainless steel cable splice closure.
Background technology
At a distance, jumbo electric power, when communication line sets up aerial optical cable because the influence of factors such as the manufacturing of optical cable, transportation, construction, traction, the delivery disc of optical cable is long limited often, so the connection device of optical cable is absolutely necessary.For the needs that guarantee to construct, continue, move and safeguard, need to use special device: connector box.Cable splice closure is an indispensable important component part in the optical cable communication line.Its major function is to realize continuing of optical cable and optical fibres; Simultaneously for guaranteeing the grounding function of cable splice closure; Electrical communication will be carried out in earthing device that it is inner and optical cable ground connection position; And guarantee mutually insulated between hardware and earthing device, the optical cable strengthening core of cable splice closure, to avoid from the adverse effect of environment to cable splice closure.Cable splice closure is the same with optical cable, and their quality own all play crucial effects to communications.
The application of cable splice closure is quite extensive, and fiber cable joint belongs to weak link in the lightguide cable link engineering.Design and construction that this situation and cable splice closure occur should all be undivided.Just because of this, constantly sum up the situation that cable splice closure occurs in the lightguide cable link engineering and just seem important.
At present, the connector box of typing mainly contains: (1) cydariform: form for the box body and lid two parts of the casting of aluminium box gold, heaviness and inner space are less, and the surplus fine limited length that can hold can not satisfy the requirement of special area and particular client.(2) hat type: types such as aluminium alloy type, stainless die and shaped plastics are arranged.Box body is the bigger cap structure of the degree of depth (also claiming " sub warhead "); Adopt C clamping hoop type fastening means or heading tape formula fastening means with the junction of base; Convenience of installing and reliability all remain further to be improved; And the space is less in the box, can not satisfy big core and count optical cable in the situation that requires long surplus fibre, and relatively difficulty is installed.
The normally loose sleeve pipe of fiber cable joint directly causes fiber winding disk from the optical cable termination, and loose sleeve pipe has no reservation in connector box, when loose sleeve pipe is flexible, is easy to the optical fiber top is disconnected or break.
The structure of cable splice closure is different; Sealing is installed complexity with also different to the flat requirement of the technology of installation personnel; Like the clamping hoop type cable splice closure technical merit of installation personnel is had relatively high expectations, if let the personnel that lack experience install, then maybe be because of the improper phenomenon that leaks air is installed.
All there is common shortcoming in aforementioned two kind connector boxs: the inner space is little, and installation specification is high, difficulty is big, or antiseptic property and impact resistance are not ideal enough.
Summary of the invention
In view of afore-mentioned and deficiency, the utility model provide a kind of structure more rationally, higher, the better adaptability of reliability, novel cable splice closure easy for installation.
