Detailed description of preferred embodiment
Optical fiber connector of the present invention or line end be at Fig. 1, is described in 2 and 3, and wherein Fig. 1 is a stereographic map, and Fig. 2 is the cut-open view of Fig. 1, and Fig. 3 is the enlarged drawing at the connector tip shown in Fig. 2.As Fig. 1, shown in 2 and 3, the end of connector 10 about bundle cables 12.Optical cable 12 comprises fiber sheath 14, and it is around cushion pad 16, and cushion pad is around light transmitting fiber 18, so that the tip 20 of light transmitting fiber 18 is projected on the tip of connector 10.
Connector 10 comprises the inner wire end member spare 24 of a general cylindrical and the outer lines end member spare 28 of a general cylindrical.Inner wire end member spare 24 comprises the hole 30 that first axially is provided with, and its diameter is enough to make fiber sheath 14 to be slidingly matched.The length in hole 30 is enough to allow the ripple 32 of inner line end 24 to arrive fiber sheath 14 usually.Axially the diameter of the endoporus 36 that is provided with can make cushion pad 16 be slidingly matched at this, and hole 36 is arranged on the internal end surface 40 in hole 30.Shoulder 44 is arranged on the outside surface of cylindrical interior line end 24, has formed the nose part 48 of inner line end 24 like this.Nose part 48 comprises a taper convergence portion 52, and this part ends at outstanding forward compressing and installs most advanced and sophisticated 56.Compress and install most advanced and sophisticated 56 and comprise that a light transmitting fiber hole that axially is provided with 60 passes through at this, so that light transmitting fiber 18 passes light transmitting fiber hole 60.
Outer lines end member spare 28 comprises the body 68 of a general cylindrical, it comprises the intilted conical portion 72 that an integral body is provided with, this part ends at one and compresses the most advanced and sophisticated branch 76 of installation, is compressing the connector matching surface 80 that the front portion that the tip is installed is provided with a polishing.Inner line end jack 84 is axially disposed within the outer lines end member spare 28, so that the nose part 48 of inner wire end member spare 24 reaches the inside.Hole 84 ends at an inwardly outstanding conical pressing surface 88, and surface 88 ends at another internal holes 92.Hole 92 ends at an inside round taper hole 94, and hole 94 ends at a light transmitting fiber through hole 96 that axially is provided with, and is projected into its tip 20 by through hole 96 light transmitting fibers 18.
As what can be clear that in Fig. 3, the outer rib part at outside line end tip 76 produces variant part 100 by mechanical means, causes exterior section 102 mechanically deforms in light transmitting fiber hole 96 like this.Crushed element 102 is used for light transmitting fiber 18 machineries, frictionally constraining in the tip 76 of outer lines end member spare 28.By same method, the outer rib part at inner line end tip 56 produces variant part 106 by mechanical means, causes the exterior section in light transmitting fiber hole 60 to produce mechanically deform part 108 like this.Mechanically deform part 108 is with light transmitting fiber 18 machineries, frictionally constrain in inner wire end member spare 56.
Therefore, can know, two line end optical fiber connectors 10 comprise machinery, the frictional constraint point of two different light transmitting fibers 18 that separate in connector 10, these points are respectively outside and the tip 76 of inner wire end member spare 28 and 24 and the mechanically deform part 102 and 108 at 56 places.
Fig. 4,5 and 6 show the step of the method for optimizing that is used for two line-end connectors shown in the manuscript 1-3 and above-described.As shown in Figure 4, inner line end 24 is placed on the optical cable 12, so that fiber sheath 14 is stayed in the hole 30.Line end 24 is crushed on light transmitting fiber 12 subsequently.Outside subsequently line end 28 is placed on the outstanding light transmitting fiber 18 and is moved down into inner line end 24, and 88 contact with the tip 56 of inner line end 24 up to the interior conical of outside line end 28 surface, as shown in Figure 5, are further discussed below.
As shown in Figure 5, outside line end 28 is placed on the inner line end 24, so that inner inclination face 88 contacts with the outer rib at the tip 56 of inner line end 24.This electrical connector is placed into and compresses in the erecting device subsequently, and as described in my U.S. Patent application 08------number of 8,96 on Mays applications, the content of its disclosure all is incorporated into this.Therefore, as shown in Figure 5, the nose part 76 of outside line end 28 is held in place in the round taper hole in the nose part 118 that compresses drive unit 120.The jag of light transmitting fiber 18 is positioned to be arranged on and compresses the center pit 122 that drives nose part 118.Can notice, most advanced and sophisticated 76 outer rib part 126 contacts with the surface of round taper hole 114, and simultaneously, the outer rib 110 at the tip 56 of inner line end contacts with the surface of round taper hole 88, between the afterbody part 132 of the body 68 of the shoulder 44 of inner line end 24 and outside line end 28 gap 130 is arranged.The afterbody part 136 of inner line end 24 leans against on a static block or the anvil 140, and block 140 comprises a passage that runs through 144, is used to make optical cable 12 to pass through from here.The effect that compresses driver 120 is described below by means of Fig. 6.
Fig. 6 shows with compressing driver 120 connector 10 that compresses is installed.As shown in the figure, the effect that compresses driver 120 is that outside line end 28 is pressed onto on the inner line end 24, simultaneously, makes the most advanced and sophisticated rib 110 of most advanced and sophisticated rib 126 of outside line end and inner line end produce mechanically deform.Therefore, as shown in Figure 6, the most advanced and sophisticated rib of outside line end produces mechanically deform 100, and most advanced and sophisticated 76 interior light transmitting fiber holes 96 generation machineries subside 102 thus, will be by light transmitting fiber 18 frictional constraints herein.By same method, the outer rib 110 of inner line end nose 56 produces mechanically deform 106, and thus, most advanced and sophisticated 56 interior light transmitting fiber holes 60 produce machineries and subside 108, will be by light transmitting fiber 18 frictional constraints herein.Can also see, because the compressional movement of outside line end 28 on inner line end 24 reduces gap 130.
Therefore, can know, the method for optimizing of processing connector 10 is to use single compaction step, light transmitting fiber 18 produces two machineries, frictional constraint in connector 10 like this, internal constraint 108 and second externally frictional constraint 102 at most advanced and sophisticated 76 places of line end at most advanced and sophisticated 56 places of inner line end.
