Abstract

A polarized connector comprises a connector body having an opening for receiving a polarization key. The key comprises a polarization member and slotted shaft rotatable in the opening about a longitudinal axis. The slotted shaft permits user access to the key to rotate the key within the opening in the connector. The polarized connectors described herein permits simple polarization changes with a single key element that is retained with the connector for all polarization configurations.

Claims

1. A polarized connector comprising:

a connector having a channel, a substantially circular opening, and a receiving element,

a polarization member received by and rotatable within said opening, said polarization member having a plurality of rotational orientations corresponding to connector polarization modes wherein said polarization member is received by said receiving element in one of the polarization modes such that a top surface of said polarization member is flush with a bottom surface of said channel.

2. The polarized connector as recited in claim 1 wherein said receiving element comprises a landing and a secondary boss member.

3. The polarized connector as recited in claim 2, said receiving element further comprising at least one post extending upwardly therefrom, the top of said post being coplanar with said landing, and wherein said polarization member key has at least one slot corresponding to and receiving said post.

4. The polarized connector as recited in claim 1 further comprising a slotted shaft and a locking projection on said shaft.

5. The polarized connector as recited in claim 4 wherein said polarization member and said shaft are molded as a unitary body.

6. The polarized connector as recited in claim 4 wherein said shaft further comprises at least one detent on a circumferential periphery of said shaft.

7. The polarized connector as recited in claim 1 wherein said polarization member comprises a multimode polarization profile on a top surface of said polarization member.

8. The polarized connector as recited in claim 1 wherein said polarization member comprises a singlemode polarization profile on a top surface of said polarization member.
