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 having a distal end and a proximal end spaced from the distal end in a proximal direction along an axis, the connector housing comprising:

an inner cavity structure to accept a ferrule assembly, wherein the ferrule assembly comprises a collar having a plurality of contact points at a proximal end of the collar;

an alignment sleeve extending along the axis, the alignment sleeve comprising a plurality of angled surfaces circumferentially spaced about the axis and a plurality of openings interleaved between the plurality of angled surfaces about the axis, each of the angled surfaces facing radially inwardly toward the axis, each opening extending longitudinally along the axis away from the angled surfaces in the proximal direction, each angled surface sloping radially inwardly with respect to the axis and toward a respective one of the openings as it extends along the axis in the proximal direction,

the angled surfaces and openings are molded as part of the inner cavity structure;

a bias spring engaging a distal end of the collar opposite the contact points;

a backbody inserted at the distal end of the housing capturing the bias spring between the backbody and the distal end of the collar,

the backbody compresses the bias spring to create a spring force,

the spring force created by the compressed spring rotates each of the contact points of the collar along the corresponding angled surface until the contact points are received within the corresponding opening thereby securing the ferrule assembly within the alignment sleeve without jamming the ferrule assembly within the alignment sleeve.

2. The connector housing according to claim 1 wherein the angled surface is oriented at an angle of about 10 degrees to 45 degrees with respect to the axis.

3. The connector housing according to claim 1, wherein the connector housing is selected from a LC, SC, MPO or CS connector housing.

4. The connector housing according to claim 1, wherein the collar is annular.

5. The connector housing according to claim 1, wherein the collar is square.

6. The connector housing resulting in the configuration of claim 1.

7. A method of assembling the connector comprising:

providing the connector housing for claim 6;

inserting the ferrule assembly into the cavity of the connector housing;

inserting the bias spring at the distal end of the ferrule assembly;

securing the backbody to the distal end of the connector housing; and

wherein inserting the backbody compressing the spring results in rotating the ferrule assembly within the cavity without jamming the ferrule assembly within the cavity.

8. A connector housing comprising a body defining an alignment sleeve extending along an axis, the alignment sleeve being configured to receive a ferrule assembly including a flange having a plurality of sides, the alignment sleeve comprising a ferrule guide portion and a ferrule receiver portion extending longitudinally away from the ferrule guide portion in a first axial direction, the ferrule receiver portion having a plurality of longitudinally extending sides defining a flange recess sized and arranged to matingly receive the flange of the ferrule, the plurality of longitudinally extending sides comprising a first longitudinally extending side and a second longitudinally extending side that meet at a vertex extending longitudinally along the axis, the ferrule guide portion having at least one angled guide surface facing radially inwardly toward the axis and extending longitudinally along the axis, the at least one angled guide surface sloping radially inwardly with respect to the axis and toward the vertex as it extends in the first axial direction for engaging the flange of the ferrule as the ferrule moves in the first axial direction to orient the ferrule for mating reception in the flange recess.
