Description
Technical field
The invention belongs to the fibre junction technical field, be specifically related to a kind of end tight cover fibre core butterfly leading in cable and its implementation of being prefabricated into.
Background technology
In the development of FTTH engineering, between local side and user, using the butterfly leading in cable as transmission medium, in use must consider with convenient construction, easy and simple to handle, low-loss method, optical fiber or optical cable to be connected with each other, the general flexible jumper that adopts is realized, between each flexible jumper, can realize the selectivity interworking, to realize the fast splicing of the optical link between family and corridor.
Being prefabricated into end butterfly leading in cable, being called for short by " rubber-insulated wire wire jumper ", is can reusable passive device be used to what connect that optical fiber or butterfly leading in cable form the continuous light path, is applied in optical fiber transmission line.Be prefabricated into end butterfly leading in cable and in factory, on the butterfly leading in cable, add in advance exactly a fiber connector, can by adapter, get up the accurate docking of two end faces of optical fiber at the construction field (site), so that being coupled to receive in optical fiber to greatest extent, the luminous energy of launching fiber output goes, and make because it is got involved optical link and the impact that system causes is reduced to minimum, this is the basic demand of the joints of optical fibre.To a certain extent, the joints of optical fibre have also affected reliability and the properties of optical transmission system.
In the market, being prefabricated into end type butterfly leading in cable is comprised of common butterfly leading in cable, ceramic insertion core, connector loose mail three parts.Its shortcoming is: 1, because common butterfly leading in cable is not considered the prestress that produces between oversheath and fibre core when designing, in production run, oversheath is under the pulling who is subject to internal stress, and fibre core also easily causes breaking of fibre core thereupon being pulled.2, in the process of using, be prefabricated into the operation of end butterfly leading in cable the time because of the oversheath hard-pressed bale, fibre core in the lock pin retraction process, the short-range space of fibre core section of removing oversheath can't bounce back and cause bending to fracture.3, common butterfly leading in cable is that figure of eight butterfly leading in cable is protected fibre core by coat; but when oversheath is opened stripping; special-purpose rubber-insulated wire is opened the coat that the stripping pincers open stripping place to oversheath damage; so not only can be on cold connector, connect the impact that son and the use of rubber-insulated wire wire jumper can produce optical property soon; and waste is also very large, has improved use cost.

The described a kind of tight cover of end fibre core butterfly leading in cable that is prefabricated into, it is characterized in that described reinforcement set collar is the large rear end of front end minor structure, described reinforcement set collar front end is fixed on reinforcement firm banking afterbody, and described reinforcement set collar rear end is provided with for the fixing support bracket fastened mounting hole of optical cable.
Described a kind of implementation method that is prefabricated into the tight cover of end fibre core butterfly leading in cable is characterized in that comprising the following steps:
Get ceramic insertion core, connector loose mail and tightly overlap fibre core butterfly leading in cable, the connector loose mail comprises fixed cover, spring, reinforcement firm banking, reinforcement set collar, optical cable fixed support and rear tail cover;
tail cover after overlapping successively on tight cover fibre core butterfly leading in cable, the reinforcement set collar, the reinforcement firm banking, fixed cover and spring, the protective sleeve that tightly overlaps fibre core butterfly leading in cable is divested, after the colored optical fiber that will tightly overlap again fibre core butterfly leading in cable penetrates ceramic insertion core, solidify and grind, then the reinforcement firm banking be pushed into to ceramic insertion core caudal peduncle bottom and fix with fixed cover, the non-metal reinforcement member that then will tightly overlap again fibre core butterfly leading in cable is fixed in the U-shaped groove that the both sides of reinforcement firm banking arrange and fixes with the reinforcement set collar, then with being arranged on the outer cover that the optical cable fixed support in the reinforcement set collar is fixed tight cover fibre core butterfly leading in cable, finally push to rear tail cover.
The above-mentioned a kind of tight cover of end fibre core butterfly leading in cable that is prefabricated into, reasonable in design, simple in structure, tension is effective, compared with prior art, has following beneficial effect:
1) increased the fixed function of non-metal reinforcement member, strengthened being prefabricated into the pull resistance of end butterfly leading in cable, under the prerequisite of the protective value of not losing former covered wire cable, make the fibre core have the duplicate protection performance, avoided removing breaking of fibre core after the protection oversheath;
2) tightly overlap fibre core butterfly leading in cable and can make oversheath hold stripping can directly not hold stripping to the coat of colored optical fiber, reduced colored optical fiber because without coat is normal, disconnected fine problem occurring, namely coat is not damaged, and the loss of light has just reduced;
3) tightly overlap fibre core butterfly leading in cable can confirm accurately colored optical fiber open the stripping length (comprise protective sleeve open the stripping length) according to rubber-insulated wire wire jumper loose mail structural confirmation, open stripping length, the tension better effects if, transmission performance is better, and in design, the time only need consider the flexibility of colored optical fiber, can guarantee to stretch and do not affect the loss that bending causes;
4) separating of the protective sleeve of butterfly leading in cable and oversheath, increased the crooked buffer zone of optical fiber, the disconnected fibre that has occurred while having avoided colored optical fiber because of retraction.
