Embodiment

Extremely shown in Figure 12 as Fig. 1, in the built-in type joints of optical fibre first embodiment of the present utility model, the described built-in type joints of optical fibre comprise lock pin 95, be arranged at the chuck 80 of the pre-buried optical fiber 15 in the described lock pin 95, fixing described pre-buried optical fiber crust and fix the tail shell 20 of another optical fiber crust, the described built-in type joints of optical fibre also comprise the fixedly stationary installation of cell body 50, chuck 80 and tail shell 20, and the two ends of described chuck 80 are connected with cell body 50 and tail shell 20 respectively.Pre-buried optical fiber is in process of production, one section pre-buried optical fiber 15 is inserted lock pin 95, and put glue and carry out heat curing, and then grind, and like this, the end face of the connector after the assembling has just had no difference with common wire jumper.

Wherein, described stationary installation comprise from outside to inside the inside casing cover 10 that is provided with, back-moving spring 30, fixing naked fibre and with described inside casing cover 10 prevent described naked fine rotation flange 40, spacing card 60, locking optical fiber chuck 80 and assist the ejector sleeve 90 of described chuck 80 lockings.Described spacing card is arranged on the described inside casing cover 10, and described back-moving spring 30 is arranged between described inside casing cover 10 and the ejector sleeve 90.Below each parts is illustrated respectively: described cell body 50 comprises projection, first through hole and " V " groove, and described projection is a prismatoid, and described first through hole is the triangle through hole that is arranged at described cell body 50.Cell body 50 is made up of three parts, comprises projection, first hole and V groove all, and bossing is body in echelon, and first through hole is a delthyrium, and only open at last groove in the hole, and following groove does not have the hole.Described pot shell 70 is a hollow circular cylinder, and described hollow circular cylinder is provided with the groove that convenient described cell body 50 inserts.

Pot shell 70 be shaped as hollow circular cylinder, on open groove, make things convenient for the insertion of V groove.In V groove insertion pot shell 70, projection can partly be exposed at pot shell 70 outsides.Described chuck 80 comprises outer chamfering, main body, distortion groove, limit body, interior cylinder, second through hole of guiding and the paw that tightens up, and described paw is two paws that distribute up and down.Described ejector sleeve 90 is that the metal tube by two in big footpath, path connects and composes, described big footpath for the one end push the back to " V " thus the big footpath that groove produces pressure and tightens up fixing naked fibre.Wherein, an end in big footpath pushes the back V groove is produced pressure, thereby the V groove tightens up fixing naked fibre.One end of path pushes and can make paw produce deformation, thereby two paws are held fixed fiber tightly.The inside casing cover 10 of 10 pairs of common connectors of inside casing cover improves, because the change of the fixing means of spring 30, this inside casing cover 10 has been introduced the structure of similar Wire fastener, in the production run, earlier spring 30 is compressed, insert spacing card 60 then, trip spring 30 again, and spring 30 will be fixed like this.

Described tail shell 20 comprises guide way, fastener, Ka Tai, hole clipping and optical cable through hole.Tail shell 20 cooperation inside casings overlap 10 1 and reinstate.Guide way is to insert inside casing cover 10, prevents rotation, and fastener prevents retreating of optical cable after inserting inside casing cover 10, and Wire fastener is inserted the optical cable crust by the hole clipping on the Ka Tai, just can fix whole optical cable.Flange 40 can also prevent lock pin 95 rotations with inside casing cover 10 together except fixing lock pin 95.

In this structure, flange 40 and pot shell 70 are to combine together.

This novel principle of work is as follows: the interior cylinder of chuck 80 inserts pot shell 70, the body of meeting crimp groove after ejector sleeve 90 pushes, thus two paws of body are held tightly mutually, reach the effect of fixing this part optical fiber.Tail shell 20 and inside casing cover 10 are used, and after the fastener of tail shell 20 inserts inside casing cover 10, by Wire fastener, just can fix whole optical cable.

This novel use step:

1, connector is put into the left side of assembly or fitting table, and is fixed, moving stop makes baffle plate be close to the end face of lock pin 95, fixed dam to lock pin 95 places then.

2, optical cable is passed sheath successively, tail shell 20, fiber end face is made in fiber stripping then.

3, ready-made fibre is inserted by chuck 80, by the stationary installation on the assembly or fitting table optical cable is fixed then.

4, ejector sleeve 90 is pushed, make its tail end basic consistent with the tail end of chuck 80.

5, tail shell 20 is pushed inside casing cover 10, depress Wire fastener then.

6, sheath is pushed to, and loaded onto outer frame set.

Like this, whole connector just assembling finishes.Certainly, we also can check, the end face situation of connector is wanted to polish determining again.Because in the lock pin one section pre-buried optical fiber is arranged, and the glued and grinding through factory of the end face of this section optical fiber, so all be guaranteed on from the performance to stability.
