Abstract

Embodiments disclosed herein are directed to a device and system of devices including: a connector housing comprising an alignment sleeve therein with a plural of angled surface and at least one opening, or an internal cavity of said connector housing has the same configuration as said alignment sleeve. Upon inserting ferrule assembly within an opening of said housing, a contact point on a collar or flange of said assembly moves along angled surfaces until it engages an opening between angled surfaces for securing ferrule assembly within connector housing without jamming.

Claims

1. A connector housing comprising:

a first end with a cavity configured to accept a ferrule assembly;

an internal alignment sleeve further comprising an opening and a plural of angled surfaces between said opening for aligning said ferrule assembly;

a contact point on a collar of said ferrule assembly that rotates along said angled surface of said alignment sleeve under force of a biasing component; and

wherein upon full insertion of said ferrule assembly said contact point engages said opening for properly aligning and orientating said ferrule assembly within said housing.

2. The connector housing of claim 1, wherein said angled surfaces is about 10 degrees to about 45 degrees.

3. The connector housing of claim 1, wherein number of openings is equal to or greater than the number of contact points on said collar of ferrule assembly.

4. The connector housing of claim 1, wherein said ferrule assembly is inserted from a second or proximal end of said connector housing.

5. The connector housing of claim 1, wherein said cavity is configured with said opening and said plural of angled surfaces for receiving, aligning and orientating said ferrule assemble.

6. The connector housing of claim 1, where said connector housing is part of a LC, SC, MPO or CS connector.

7. The connector housing of claim 1, wherein said ferrule assembly collar is circular with said plural of surfaces.

8. The connector housing of claim 1, wherein said ferrule assembly collar is square with said plural of surfaces.

9. The connector housing of claim 6, wherein said ferrule assembly is used with a LC connector, SC connector, MPO connector or CS connector.

10. The connector housing of claim 1, wherein assembling said connector housing to form a connector further comprises:

inserting a ferrule assembly into said cavity of said housing;

placing a biasing member at a first end of said ferrule assembly;

inserting a back body member over said biasing member;

pushing back body member toward proximal end of connector housing;

wherein continued pushing rotates said ferrule assembly along said angled surface aligning and orienting said connector within connector housing without jamming.
