Embodiment
Fig. 1-31 has described a kind of LC fiber optic industrial connector 40.Also can be with other fiber type electric wire connecting junction, as SC or ST type electric wire connecting junction.Fig. 3 has shown the component exploded view of industrial electric wire connecting junction 40.Figure 28 and Figure 29 have shown the assembling connector wing 42 of industrial electric wire connecting junction 40, and Figure 30 and Figure 31 have shown the assembling plug wing 44 of industrial electric wire connecting junction 40.
Referring to Fig. 3, the connector wing 42 for assembly industry electric wire connecting junction 40, at first connector packing washer 46 and O type circle 48 are contained in respectively on the front side and rear side of LC electric wire connecting junction support 50, form LC electric wire connecting junction bracket component, then connector face seal 54 and connector bolt 56 are contained in connector and emit on 58, emit assembly to form connector.Flexible cover 62, fluid-tight joint 64 and connector emit assembly to slide on fiber cable 66.Connector ring 60, LC electric wire connecting junction assembly and shrinkage pipe box 68 slide on fiber cable 66 successively.Use standard terminating operation chopped fibers on LC electric wire connecting junction 70 then.
Then, two terminating LC electric wire connecting junctions 70 slip into the side of LC duplex clip 72 and by the fixing (see figure 5) of LC duplex clip locking key 74, and this duplex clip locking key is buckled on the groove of LC electric wire connecting junction 70 (seeing Figure 13).Then, with this assembled on the opening of LC electric wire connecting junction support 50 front ends.In a single day LC electric wire connecting junction locking key 76 is seated in the LC electric wire connecting junction support 50 fully, therefore its depression that becomes also can not operate (seeing Figure 19).
At last, connector ring 60 and connector emit assembly sliding on the rear end of LC electric wire connecting junction bracket component and be fixed on the LC electric wire connecting junction support 50 by screw thread fluid-tight joint 64.Flexible cover 62 is screwed in the fluid-tight joint 64.In case flexible cover 62 is completely fixed, fluid-tight joint 64 is pressed on the circular fiber cable 66 and forms hermetically-sealed cable/plug interface.Alternatively, as shown in figure 29, connector can be emitted 58 be fixed on the connector ring 60.
Referring to Fig. 3, the plug wing 44 for assembly industry electric wire connecting junction 40, plug face seal 78 is assembled in the front end of plug 80, and plug packing washer bolt 82 and connector packing washer (not shown) are assembled in plug and emit on 84, and this assembly then slides on the screw thread of plug end after 80s.Alternatively, plug packing washer 86 slides on the screw thread of the rear end of plug 80.
Comprise that the compound LC adapter module 88 of compound LC adapter 90 is buckled in the rear portion of plug 80, and remained on the appropriate location by all-in-one-piece plug locking key 92.Then, the eyelet that passes on the mounting plate 94 is positioned at sub-component on any of four 90 degree orientation.Before assembly nut 96 was fixed, plug 80 can rotate by the intervals of 90 degree.Thrust washer 98 is aimed on the screw thread of plug end after 80s, and assembly nut 96 is screwed on the plug 80 with fixing whole plug assembly.Alternatively, as shown in figure 31, plug can be emitted 84 be fixed on the plug 80.
Referring to Fig. 3, supporting for the connector wing 42 and the plug wing 44 that make industrial electric wire connecting junction 40, LC electric wire connecting junction 70 is inserted in the opening of plug 80.The keyway of LC electric wire connecting junction support 50 makes LC industry electric wire connecting junction connector accurately aim at plug 80.Connector ring 60 screws in appropriate location and fixing by the pin on the connector ring 60 100, and described pin is assemblied in the groove 102 interior (seeing Figure 21 and Figure 22) on the plug 80.The cotter way fit has prevented the separation between the supporting component.
The inside component of industry electric wire connecting junction 40 is fixed in the mode that is different from typical copper or fiber industry electric wire connecting junction.The connector wing of typical industry electric wire connecting junction only keeps together at a place of cable.When flexible cover was screwed in the fluid-tight joint, this fluid-tight joint was pressed in the unique locking mechanism that forms on the cable in the typical industry electric wire connecting junction.Because the copper connector housing tightly collapses upon on the cable, therefore this mechanism might be used on the standard copper base industry electric wire connecting junction.This makes and to have a gap from time in the hole of electric wire connecting junction on inserting its electric wire connecting junction support of the typical copper base industry electric wire connecting junction connector wing.Yet this copper base connector housing is not fixed on the electric wire connecting junction support.
Only fluid-tight joint is connected to the LC industry electric wire connecting junction that can not provide firm on the fiber cable.Put from outside PVC in the shrinkage zone of fiber cable as the fruit fiber electric wire connecting junction and to get loose, may cause the LC electric wire connecting junction to move to the electric wire connecting junction support.Yet, the invention provides a kind of industrial electric wire connecting junction 40 and have the necessary additional support device of firm effect.
Shown in Figure 10-13, LC electric wire connecting junction 70 is assembled in the sidepiece of LC duplex clip 72.Then, this duplex clip/electric wire connecting junction assembly slips in the open front of LC electric wire connecting junction support 50, as demonstration is known in Figure 17 and 18.In case the LC connector housing is reduced to the minimum point in the LC electric wire connecting junction support 50, LC duplex clip/electric wire connecting junction assembly just has been seated in the LC electric wire connecting junction support 50 fully.In this, LC duplex clip locking key 104 in LC electric wire connecting junction support 50 in conjunction with and send audible clatter.As shown in figure 19, with LC industry electric wire connecting junction connector from the process that plug 80 is removed, locking key 104 prevents that LC electric wire connecting junction 70 from skidding off the front end of LC electric wire connecting junction support 50.
The design of this duplex clip has also solved the ubiquitous problem of conventional industrial electric wire connecting junction.The general assembly operation of the typical industry electric wire connecting junction connector wing need be fastened on the clamp nut of flexible cover in the fluid-tight joint.The huge moment of torsion that fastening this nut applied moves forward the cable in the electric wire connecting junction support.In a kind of traditional industrial electric wire connecting junction, because the unique holding force on the cable acts on riser runner, this promotes connector and moves forward in the electric wire connecting junction support.
Yet in the present invention, when the nut of flexible cover 62 is fixed in the fluid-tight joint 64, because duplex clip locking key 104 latches on the revetment 106 of LC electric wire connecting junction support 50 front ends, LC electric wire connecting junction 70 will can not move forward, shown in Figure 19 and 26.This retention performance makes LC electric wire connecting junction 70 fixing more accurately in the axial direction.When the connector wing 42 of industrial electric wire connecting junction 40 cooperates in the distally of LC adapter 90 with another LC electric wire connecting junction 70, the location of connector wing ring face will be more accurate.Correspondingly, this has guaranteed that the spring force on the LC electric wire connecting junction 70 is firmer, and more reliable optical measurement finally is provided.
In addition, at any time LC electric wire connecting junction 70 can be removed from the front end of LC electric wire connecting junction support 50.At first, unclamp flexible cover 62 to discharge the pressure on the cable 66.Next, the overarm 108 of LC duplex clip 72 front portions offsets downward the distance of a finger or a bottle opener, thus LC duplex clip locking key 104 is broken away from from the revetment 106 that is formed on the LC electric wire connecting junction support 50.Therefore it is moving to make that LC electric wire connecting junction 70 can be drawn forward.Discharge LC electric wire connecting junctions 70 from LC electric wire connecting junction support 50 and make in the random time after the electric wire connecting junction terminating ring face to be repolished or to amplify and reexamine, if desired like this.
The invention provides a kind of LC fiber optic industrial connector that can after terminating process or terminating, remove the LC electric wire connecting junction easily.Description and graphic embodiments of the invention and preferred embodiment are not that the present invention can be used for the exhaustive of LC fiber optic industrial connector pattern above should be appreciated that, but are used for current understanding example of the present invention or embodiment diagram.A lot of other form of the present invention is also thought and is included in this.
