Utility model content
The purpose of this utility model is in that to provide a kind of utilization rate high, can meet the double-core rubber-insulated optical cable dividing box of the networkings such as broadcasting and TV FTTH networking, telecommunications FTTH, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme:
A kind of double-core rubber-insulated optical cable dividing box, including upper cover plate and lower cover, heat-shrink tube draw-in groove, wire winding ring and fine groove it is provided with in described lower cover, described heat-shrink tube draw-in groove is positioned at lower cover center upper portion position, wire winding ring includes two curved portions, being separately positioned on down the left and right sides covered, two curved portions are arranged oppositely；Described fine groove is provided with two groups, lays respectively at down the both sides, bottom covered；Often the fine groove of group include side by side up and down set up the first fine groove of card, the second fine groove of card, the inwall of the fine groove both sides of each card is all intervally distributed with sawtooth projection with fixing optical cable；Described upper cover plate is provided with the draw-in groove adaptive with lower cover to prevent optical fiber from jumping out.
As further program of the utility model: described upper cover and lower cover fasten to seal and arrange, and upper cover plate forms waterproof sealing structure with lower cover.
As this utility model further scheme: described heat-shrink tube draw-in groove, wire winding ring, fine groove be integrated injection mo(u)lding under cover.
As this utility model further scheme: the length of described heat-shrink tube draw-in groove is less than the minimum range between two curved portions of wire winding ring, and the distance between two groups of fibre grooves is less than the minimum range between two curved portions of wire winding ring.
As this utility model further scheme: described upper cover plate, lower cover length be 95mm, width is 70mm, upper cover plate and lower cover install after height be 12mm.
Compared with prior art, the beneficial effects of the utility model are: this utility model simple in construction, reasonable in design, and lower cover part adopts integrated injection molding, and profile is succinctly attractive in appearance, it is simple to produce；Upper cover plate and lower cover realize sealing waterproof, the situation that the design of upper cover plate can effectively prevent optical fiber from jumping out in lower cover, avoid optical fiber not to be fixed easily, and use safe and reliable；Two curved portions designs of wire winding ring can reach the least radius of fibre-optical bending so that fibre-optical bending reaches without light loss；Fine groove is set to many groups and has sawtooth projection；Double-core rubber-insulated optical cable can be carried out being branched off into single covered wire cable by this utility model, then the optical fiber that branch's welding is good stretches out then through fine groove after coiling and fixing at tray interior, optical fiber can be made to bear bigger external pull, thus meeting the user demand of the networkings such as broadcasting and TV FTTH networking, telecommunications FTTH.

Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.
Referring to Fig. 1-2, a kind of double-core rubber-insulated optical cable dividing box, including upper cover plate 1 and lower cover 2, described upper cover plate 1 and lower cover 2 fasten to seal and arrange, and upper cover plate 1 and lower cover 2 form waterproof sealing structure；Being provided with heat-shrink tube draw-in groove 3, wire winding ring 4 and fine groove 5 in described lower cover 2, described heat-shrink tube draw-in groove 3, wire winding ring 4, fine groove 5 are integrated injection mo(u)lding on lower cover 2；Described heat-shrink tube draw-in groove 3 is positioned at lower cover center upper portion position, and wire winding ring 4 includes two curved portions, is separately positioned on the left and right sides on lower cover 2, and two curved portions are arranged oppositely；Described fine groove 5 is provided with two groups, lays respectively at the both sides, bottom on lower cover 2；Often the fine groove 5 of group include side by side up and down set up the first fine groove of card, the fine groove both sides of the second card each card of fine groove inwall on be all intervally distributed with sawtooth projection with fixing optical cable；The length of described heat-shrink tube draw-in groove 3 is less than the minimum range between 4 two curved portions of wire winding ring, and the distance between two groups of fibre grooves 5 is less than the minimum range between 4 two curved portions of wire winding ring；Described upper cover plate 1 is provided with the draw-in groove with lower cover 2 adaptation to prevent optical fiber from jumping out, described upper cover plate 1, lower cover 2 length be 95mm, width is 70mm, upper cover plate 1 and lower cover 2 install after height be 12mm.
Operation principle of the present utility model is: after double-core rubber-insulated optical cable 6 enters this utility model dividing box from side fibre groove 5, double-core rubber-insulated optical cable can be effectively fixed by fine groove 5, peel oversheath off, article two, single-core fiber 8 coils around wire winding ring 4, and the good other external single covered wire cable of welding or tail optical fiber 7, fusion point 9 is arranged in heat-shrink tube draw-in groove 3, it is fixing that heat-shrink tube is stuck in heat-shrink tube draw-in groove 3, single covered wire cable or tail optical fiber 7 coil again through wire winding ring 4, the fine groove 5 entering opposite side is fixed, realize the branch of double-core rubber-insulated optical cable, separate, upper cover plate 1 is covered on lower cover 2, seal protection.
Optical fiber good for welding can be stretched out then through fine groove 5 by double-core rubber-insulated optical cable dividing box described in the utility model at tray interior after coiling and fixing, optical fiber can be made to bear bigger external pull, additionally the wire winding ring 4 of arc reaches the least radius of fibre-optical bending so that fibre-optical bending reaches without light loss, and realizes the branch of twin-core and multicore.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, it is also possible under the premise without departing from this patent objective, make various change.
