Abstract

A connector comprising: (a) at least one multi-fiber ferrule having a front face presenting a plurality of fiber end faces, and a back face having a first surface and defining a first orifice through which the fibers pass; (b) a retainer for holding the at least one multi-fiber ferrule, the retainer comprising a front face having a second surface and defining a second orifice through which the fibers pass, the second surface contacting the first surface; wherein at least one of the first or second surface is convex along at least one of an x-axis or a y-axis such that the at least one multi-fiber ferrule is able to move relative to the retainer about at least one of the axes.

First claim

What is claimed is:

1. A connector comprising:
at least one non-biased, multi-fiber ferrule having a front face presenting a plurality of fiber end faces, and a back face having a first surface and defining a first orifice through which said fibers pass;
a retainer for holding said at least one non-biased, multi-fiber ferrule, said retainer comprising a front face having a second surface and defining a second orifice through which said fibers pass, said second surface contacting said first surface; wherein at least one of said first or second surface is convex along at least one of an x- axis or a y-axis such that said at least one multi-fiber ferrule is able to move relative to said retainer about at least one of said axes;
a first housing defining at least one opening to receive said at least one multi-fiber ferrule, said ferrule being at least partially disposed in said opening such that said ferrule can move along at least one of said x or y axes;
a second housing for holding said first housing, wherein said second housing defines a receptacle for receiving a second connector, wherein said connector does not comprise a spring and said second connector comprises a spring.

2. The connector of claim 1 , wherein said first or second surface is curved along at least one of said x-axis or said y-axis.

3. The connector of claim 1 , wherein said front face presents said fibers in at least one row along said x-axis, and wherein said first or second surface is convex along said x-axis.

4. The connector of claim 3 , wherein said first or second surface is curved.

5. The connector of claim 4 , wherein only said second surface is convex.

6. The connector of claim 1 , wherein said ferrule and said first surface comprise a unitary structure.

7. The connector of claim 1 , wherein said retainer comprises a slot leading to said second orifice.

8. The connector of claim 1 , wherein said at least one multi-fiber ferrule comprises two or more multi-fiber ferrules, and wherein said retainer comprises a plurality of second surfaces, each second surface configured to contact a first surface of one of said multi-fiber ferrules.

9. The connector of claim 1 , further comprising a second connector.

10. The connector of claim 1 , wherein said connector is a backplane connector.

11. The connector of claim 1 , wherein said connector does not comprise a spring.

12. The connector of claim 1 , wherein said retainer is connected to said first housing to hold said ferrule against said first housing.

13. The connector of claim 12 wherein said retainer comprises at least one alignment member configured to engage at least one corresponding alignment member of said first housing to align said retainer with said first housing.
