## Abstract

Connector assemblies having an adjustable polarity are described. A connector assembly having an adjustable polarity comprises a housing and a locking component configured to couple to the housing, the locking component including a compression element. The connector assembly further comprises a latch component configured to rotate around the locking component when the compression element is compressed 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.

## Claims

### Claim 1

A connector assembly having an adjustable polarity, comprising:
a housing having an axis;
a locking component configured to couple to the housing, the locking component including at least one compression element selectively compressible to move relative to the housing between a first position and a second position; and
a latch component configured to engage the locking component at a first location along the axis when the compression element is in the first position such that the locking component prevents rotation of the latch component about the axis, the latch component being configured to rotate around the locking component when the compression element is in the second position from a first polarity position to a second polarity position substantially without moving the latch component along the axis of the housing away from the first location to change the polarity of the connector assembly from a first polarity when the latch component is located at the first polarity position to a second polarity when the latch component is located at the second polarity position.

### Claim 2 (depends on 1)

The connector assembly of claim 1, wherein the latch component comprises at least one locking recess and the locking component comprises at least one locking element configured to engage the locking recess.

### Claim 3 (depends on 1)

The connector assembly of claim 1, wherein the housing comprises an opening and the locking component comprises a complementary projection configured to engage the opening.

### Claim 4 (depends on 1)

The connector assembly of claim 1, wherein the housing comprises at least one channel configured to receive the at least one compression element.

### Claim 5 (depends on 1)

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

### Claim 6 (depends on 1)

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.

### Claim 7 (depends on 6)

The connector assembly of claim 6, wherein the at least one thumb latch is configured to rotate with the latch component to change the polarity of the connector assembly.

### Claim 8 (depends on 1)

The connector assembly of claim 1, wherein the latch component comprises a ring portion configured to couple to the locking component.

### Claim 9 (depends on 8)

The connector assembly of claim 8, wherein the ring portion includes at least one locking recess and the locking component comprises at least one locking element configured to engage the at least one locking recess.

### Claim 10 (depends on 9)

The connector assembly of claim 9, wherein the at least one locking element is configured to disengage from the at least one locking recess when the at least one compression element is compressed.

### Claim 11 (depends on 8)

The connector assembly of claim 8, wherein the ring portion is disposed about a first end of the locking component, the locking component configured to couple to the housing at a second end of the locking component.

### Claim 12 (depends on 1)

The connector assembly of claim 1, further comprising a back post, wherein the latch component is configured to rotate without removing the back post.
