Abstract

Connector assemblies having an adjustable polarity are described. For example, at least two ferrules may be arranged in a housing of the connector assembly within independent frame plugs in a certain polarity. A top portion of the housing may be removed to allow access to the frame plugs. Accordingly, an installer may open the housing, switch the polarity of the ferrules, and then re-couple the top portion to the housing. In another example, the connector assembly may include a latch that may rotate about the connector assembly from a first polarity position to a second polarity position. The connector assembly may include a compression element that may facilitate the rotation of the latch when the compression element is compressed. In this manner, the latch may be rotated to a different polarity position to allow the connector assembly to be connected to an adapter using a different polarity.

First claim

What is claimed is:

1. A connector assembly having an adjustable polarity, comprising:
a first ferrule and a second ferrule;
a frame comprising an integrated plug frame portion and a back post portion, the frame being configured to receive the first ferrule and the second ferrule; and
a latch component configured to rotate around the frame to change the polarity of the connector assembly from a first polarity when the latch component is located at a first polarity position to a second polarity when the latch component is located at a second polarity position, without removing the first ferrule and the second ferrule from the frame, wherein the latch component comprises a ring portion including at least one locking projection configured to engage the frame to prevent rotation of the latch component relative to the frame.

2. The connector assembly of claim 1 , wherein the latch component is configured to engage the frame to prevent rotation of the latch component relative to the frame.

3. The connector assembly of claim 2 , wherein the frame comprises at least one locking recess and the latch component comprises at least one locking projection configured to engage the locking recess.

4. The connector assembly of claim 2 , further comprising at least one compression element configured to disengage the latch component from the frame when the at least one compression element is compressed, thereby allowing the latch component to rotate around the frame.

5. The connector assembly of claim 4 , further comprising at least one locking element configured to engage at least one locking recess arranged on the latch component when the compression element is not compressed, thereby preventing rotation of the latch component.

6. The connector assembly of claim 1 , wherein the connector assembly is a duplex LC-type connector.

7. The connector assembly of claim 1 , wherein the latch component comprises at least one thumb latch configured to secure the connector assembly to an adapter.

8. The connector assembly of claim 7 , wherein the at least one thumb latch is configured to rotate with the latch component to change the polarity of the connector assembly.

9. The connector assembly of claim 1 , wherein the ring portion further includes at least one compression section configured to allow disengaging the latch component from the frame.

10. The connector assembly of claim 1 , wherein the frame comprises a bottom frame portion and a top frame portion configured to couple to the bottom frame portion to enclose the first ferrule and the second ferrule.

11. The connector assembly of claim 10 , each of the bottom frame portion and the top frame portion having a respective integrated plug frame portion and a back post portion.

12. The connector assembly of claim 10 , wherein the latch component is configured to rotate from the top frame portion to the bottom frame portion to change the polarity of the connector assembly.

13. The connector assembly of claim 12 , wherein the latch component is further configured to rotate from the bottom frame portion to the top frame portion to change the polarity of the connector assembly.

14. The connector assembly of claim 1 , wherein the latch component is configured to rotate without removing the latch component from the back post portion.
