Abstract

An optical connector assembly a first structure and a second structure, the two structures secured together using a retention structure to form a hybrid assembly. The retention structure uses a slot apex located in a slot channel for securing at least one latch pin of a coupling nut to an adapter housing forming the ingress protected connector without the use of a bias spring. The hybrid assembly is designed to resist water or debris ingress, and may eliminate the use of a bias force to further resist separating the hybrid assembly.

First claim

What is claimed is:

1. A retention structure for securing two dissimilar fiber optic devices to form a hybrid assembly comprising:
a protrusion on a surface of first fiber optic device;
a slot on a corresponding surface of a second fiber optic device;
said slot has an opening at a first end and is closed at second end;
an apex positioned along an inner surface of said slot; and
wherein the first fiber optic device and the second fiber optic device are configured to be mated along a longitudinal axis to form the hybrid assembly;
wherein the apex is sized and shaped to allow said protrusion to pass beyond said apex forming the hybrid assembly;
wherein the slot extends perpendicular to the longitudinal axis from the apex to the closed end.

2. The retention structure of claim 1 , wherein
said apex has a first chamfer and second chamfer, and further wherein the first chamfer has a more gradual slope than the second chamfer.

3. The retention structure of claim 1 , wherein the protrusion and the slot are configured so that the protrusion reaches a retention position after passing the apex and wherein the retention structure secures the first fiber optic device and the second fiber optic device in the hybrid assembly when the protrusion is at the retention position.

4. The retention structure of claim 1 , wherein the retention structure is springless such that the apex retains the protrusion at the retention position without a bias spring acting on the protrusion.

5. A retention structure for securing two dissimilar fiber optic devices to form a hybrid assembly comprising:
a protrusion on a surface of first fiber optic device;
a slot on a corresponding surface of a second fiber optic device, and having an opening at a first end and closed at second end; and
an apex positioned along an inner surface of said slot and dividing the slot into a first section and second section extending in different directions; and
wherein the apex is sized and shaped to allow said protrusion to pass beyond said apex to enter the second section of the slot.

6. The retention structure of claim 5 , wherein the second section extends in a direction perpendicular to the mating direction of the two fiber optical devices.
