Abstract

Claims (45)

1 . A method of reversing a polarity of a connector assembly, the connector assembly including a connector subassembly and a latch having a plurality of latch arms, the latch coupled to the connector subassembly; the method comprising:

removing a boot assembly from the connector subassembly;

removing the latch from the connector subassembly by applying an upward force onto the latch;

inverting one of the latch and the connector subassembly from a first orientation to a second orientation about a central axis of the latch or a central axis of the connector subassembly;

applying the latch onto the connector subassembly at a front end of the connector subassembly.

2 . The method of claim 1 , further comprising:

disengaging the latch from the boot assembly coupled to the connector subassembly by applying a downward force onto a rear protrusion of the latch.

3 . The method of claim 1 , wherein the latch has the first orientation before being removed from the connector pre-assembly, and wherein the inverting step includes rotating the latch 180 degrees about the central axis of the latch to the second orientation.

4 . The method of claim 3 , wherein the inverting step further includes rotating the boot assembly 180 degrees about a central axis of the boot assembly.

5 . The method of claim 1 , wherein the latch further includes at least one flex arm extending from a rear portion of the latch and a centering member extending from the rear portion of the latch, wherein the latch is coupled to the connector subassembly when the centering member is inserted into a centering slot of the connector subassembly.

6 . The method of claim 5 , wherein removing the latch includes applying an upward force onto the latch such that the centering member is removed from the centering slot and then applying a lateral force such that the latch is removed from the connector subassembly.

7 . The method of claim 1 , wherein removing the boot assembly includes sliding the boot assembly such that the boot assembly disengages from the connector subassembly.

8 . The method of claim 1 , further including coupling the boot assembly onto the connector subassembly and the latch in the second orientation.

9 . The method of claim 1 , wherein the connector pre-assembly has the first orientation before removing the latch from the connector pre-assembly, and wherein the inverting step includes rotating the connector subassembly 180 degrees about a central axis of the connector subassembly to the second orientation.

10 . The method of claim 1 , wherein the connector subassembly includes at least one ferrule assembly comprising a ferrule coupled to a ferrule holder, wherein the ferrule holder is within a clip carrier that has a protrusion along a bottom surface of the clip carrier that engages with the connector subassembly thereby coupling the ferrule and the ferrule holder to the connector subassembly.

11 . The method of claim 1 , wherein the latch includes a pair of guide bodies on a front end of the latch that are received onto the front end of the connector subassembly.

12 . A method of assembling an optical fiber connector assembly and reversing the polarity of the optical fiber connector assembly, the method comprising:

inserting a ferrule into a connector subassembly;

cleaving an optical fiber;

inserting the optical fiber into a rear end of the connector subassembly and into an internal bore of the ferrule;

securing the optical fiber to ferrule with an adhesive;

coupling a boot assembly to a rear end of the connector subassembly; and

coupling a latch onto a front end of the connector subassembly, wherein a rear end of the latch is coupled to the boot assembly;

the rear end includes at least one flex arm and a centering member extending from the rear portion of the latch, wherein the centering member engages with a centering slot of the connector subassembly to couple the latch to the connector subassembly.

13 . The method of claim 12 , wherein cleaving the optical fiber occurs after the optical fiber is inserted into the rear end of the connector subassembly and before the optical fiber is inserted into the internal bore of the ferrule.

14 . The method of claim 12 , further including:

disengaging the latch from the boot assembly;

removing the boot assembly;

removing the latch from the connector assembly by applying a force onto the latch such that the centering member of the latch is removed from a centering slot of the connector subassembly;

inverting the latch or the connector subassembly from a first orientation to a second orientation about a central axis of the respective latch or the respective connector subassembly; and

applying the latch onto the connector subassembly.

15 . The method of claim 14 , wherein the inverting step includes rotating the latch 180 degrees about the central axis of the latch to form an inverted latch; and

wherein the applying the latch step includes applying the inverted latch onto the connector subassembly.

16 . The method of claim 15 , wherein the inverting step further includes rotating the boot assembly 180 degrees about a central axis of the boot assembly.

17 . The method of claim 14 , wherein the inverting step includes rotating the connector subassembly 180 degrees about the central axis of the connector subassembly to form an inverted connector subassembly; and

wherein the applying the latch step includes applying the latch onto the inverted connector subassembly.

18 . A method of reversing a polarity of a connector assembly, the connector assembly including a connector subassembly and a latch having a plurality of latch arms, the latch coupled to the connector subassembly; the method comprising:

removing a boot assembly from the connector subassembly;

removing the latch from the connector subassembly by applying an upward force onto the latch;

inverting one of the latch and the connector subassembly from a first orientation to a second orientation about a central axis of the latch or a central axis of the connector subassembly;

applying the latch onto the connector subassembly at a front end of the connector subassembly;

wherein the latch further includes at least one flex arm extending from a rear portion of the latch and a centering member extending from the rear portion of the latch, wherein the latch is coupled to the connector subassembly when the centering member is inserted into a centering slot of the connector subassembly.

19 . The method of claim 18 , further comprising:

disengaging the latch from the boot assembly coupled to the connector subassembly by applying a downward force onto a rear protrusion of the latch.

20 . The method of claim 18 , further including coupling the boot assembly onto the connector subassembly and the latch in the second orientation.
