Description

A kind of optical cable connecting box

Technical field

The utility model relates to optical fiber splicing device, relates in particular to a kind of optical cable connecting box.

Background technology

Optical cable will form by the mode that optical fiber connects the network of fiber optic cable communications; so; the equipment that optical fiber connecting box connects as optical fiber; be widely used in the network of fiber optic cable communications; optical fiber connecting box wants to be applicable to built on stilts, the pipeline of various optical cables and the conditional request that the direct-burried lamp is installed, and waterproof, fire-retardant and anticollision effectively played protection preferably to stretching and the torsion of optical cable; especially to guarantee under abominable natural environmental condition, can guarantee all the time outstanding bright communication quality.Chinese patent 201120363873.0 discloses a kind of " fiber optic closure ", solved preferably the problem that fibre junction connects, be adapted at the lighting condition operation that continues under environmental baseline preferably, if the environmental baseline of down-hole under, even use explosion-proof shell instead, also can show to such an extent that operation is very inconvenient, especially due to the operating environment inclement condition of down-hole, be easy to cause optical fiber insecure problem that continues.The prior art fine dish that continues, profile is square or oval pattern, base, the sleeve pipe pickup groove of fine dish all are completely fixed.Be in a word fine moving, coil motionless.Namely fine dish is changeless, completes the fine work of dish by the method for winding optical fiber in the fibre dish.After fused fiber splice is completed, first the sleeve pipe after pyrocondensation is positioned in pickup groove one by one, and then processes the remaining fibre in both sides.Perhaps fold from the optical fiber of a side, the stationary heat draw, and then it is remaining fine to process opposite side.The fine mode defective of the dish that traditional structure brings: general optical cable welding is divided into dials fibre, welding, fine 3 key steps of dish, wherein maximum to coil fine difficulty.Be easy to completed optical fiber is fractureed in the fine process of dish; The site environment situation differs, as special engineering occasions such as down-holes, for example rather dark, environment is dirty and messy, wind is large, can't steadily lay splice tray, all greatly increased the dish fine difficulty; To fine dish, particularly in the situation that welding core number is many, the fibre that the coils coiling that all mixes in later maintenance, can bring very burden when needing dismounting or adjustment optical fiber with heat-shrink tube both sides fiber reel.

The utility model content

The purpose of this utility model is, overcomes the deficiencies in the prior art part, and a kind of optical cable connecting box is provided, and can better simplify the program of the operation that continues, and convenient comparatively carries out the operation that optical fiber continues under the rugged environment condition in the down-hole etc.

A kind of optical cable connecting box described in the utility model includes into fine hole, leads fine post, box body, fibre try to get to the heart of a matter seat, newel, fine dish, sleeve pipe pickup groove and optical fiber hole.Box body is the body supports part of a kind of optical cable connecting box described in the utility model, integral body is the box like structure of rectangular parallelepiped form, in the middle position of box body, be provided with the fibre seat of trying to get to the heart of a matter, in the try to get to the heart of a matter middle position of seat of fibre, be provided with newel, be set on newel, be provided with fine dish, make fine dish to rotate centered by newel, be positioned at the both sides of newel in the fibre dish, be provided with the sleeve pipe pickup groove.In the two ends of box body, be provided with and lead fine post, lead fine post and adopt the form that sets in a row.An end at box body is provided with into fine hole, and the other end at box body is provided with optical fiber hole.Be provided with top cover above box body, for hermetically-sealed construction, should meet the requirement of essential safety after box body and top cover cover tightly.Try to get to the heart of a matter seat and lead fine post and all be fixed in optical cable connecting box of fibre, wherein lead can try to get to the heart of a matter seat with fibre at the bottom of the post of fine post in one plane also can be not in one plane.The try to get to the heart of a matter effect of seat of fibre is to lay fine dish in self inside, and fibre the try to get to the heart of a matter center of seat has newel to coil post as fibre, embeds fine dish by the mode of pegging graft.The effect of leading fine post is that remaining fibre can be wrapped in leads on fine post after most of Optical Fiber Winding is in the fine dish, and the while can be come by different winding routes the purposes of every fibre of identification.The central authorities of fine dish are provided with fine dish hole, can peg graft with newel, make fine dish can be embedded into fibre and try to get to the heart of a matter in seat, and can rotate freely.Simultaneously fine dish centre position also has the sleeve pipe pickup groove, is used for card heat release Heat-Shrinkable Tubings, and Optical Fiber Winding is on the circular conduit in the fibre dish outside, this circular conduit refer to try to get to the heart of a matter fibre plate, top board and sidewall consist of around fine conduit.Fine dish top cover is exactly a common plastic board, and there is a short and small cylindrical fine dish post draw-in groove centre, can be socketed with newel.Fine dish top cover is tried to get to the heart of a matter between seat with fine dish and fibre, and fine dish is pegged graft with newel by the fibre dish hole at center, is embedded in fibre and tries to get to the heart of a matter in seat, optical fiber can be taken in the conduit of fibre dish periphery by the mode of rotation, then buckles fibre and coils top cover.Wherein, the fibre seat of trying to get to the heart of a matter can be embedded in a plurality of fine dishes, can settle by the mode of stack between fine dish.The fibre of the present utility model seat of trying to get to the heart of a matter is fixed, and it is fine that included round turntable is used for rotating disc, and the sleeve pipe pickup groove is fixed in can be with turntable rotation in round turntable.Concrete dish method for fiber: dish is moving, and is fine motionless.Be that optical fiber is not need manually coiling, complete the fine work of most of dish by the way of rotating fine dish.After fused fiber splice is completed, at first the sleeve pipe after pyrocondensation is positioned in pickup groove one by one, turn fibre dish is coiling to the major part of unnecessary optical fiber in fine dish, and remaining fraction optical fiber is separated the optical fiber of different length by the fine post of leading outside the fibre dish.

A kind of optical cable connecting box described in the utility model, one-piece construction is simple, and is easy for operation, good stability, reliability is high.Use a kind of optical cable connecting box described in the utility model, can simplify preferably the program of the operation that continues, convenient comparatively carry out the operation that optical fiber continues under the rugged environment condition in the down-hole etc.Especially in the most of remaining fine process of coiling, by the method for rotating disk, remaining fine inventory can be entered pallet, and omit the manual fine process of coiling, greatly reduce the fine risk of bringing disconnected fibre of manual dish; Optical fiber can be led the routed path mode of fine post in fibre dish outside by being wound around difference, different fiber is separated, in later maintenance, can pass through different routed paths, distinguish out like a cork the purposes of every core fibre, very clear, bring great convenience for removing and adjust optical fiber in later maintenance.
