Abstract

A hybrid ingress protection adapter and connector assembly, connecting the housing with a releasably replaceable connector and power assembly to an adapter that is mount on a panel. The connector has a pair of lead-ins that protect a ferrule of a plural of fiber optic connectors, and the lead-ins are of varying length allow blind mating of the connector assembly with the adapter assembly.

First claim

The invention claimed is:

1. An adapter for connecting a fiber optic and/or electrical connector to another fiber optic and/or electrical connector, the adapter comprising:
a tubular body having opposite, first and second open ends spaced apart along an axis of the tubular body, the first open end being configured to accept one of the fiber optic and/or electrical connectors and the second open end being configured to accept the other of the fiber optic and/or electrical connectors, the tubular body further including an internal wall extending around the axis and defining an internal cavity of the tubular body;
a seat in the tubular body, the seat being formed with keying structure comprising a first arcuate recess extending along a circumference of the internal wall a first distance and a second arcuate recess extending along the circumference of the internal wall a second distance less than the first distance whereby the keying structure restricts the orientation of the fiber optic and/or electrical connector when received in the first open end of the tubular body.

2. The adapter of claim 1 wherein the first arcuate recess is located in a diametrically opposite position along the internal wall from the second arcuate recess.

3. The adapter of claim 2 wherein the first and second arcuate recesses each have a central portion and opposite end portions, the radial widths of the end portions being greater than the radial width of the central portion.

4. The adapter of claim 1 wherein the seat is formed to receive a clip for attachment of an adapter clip insert to the adapter.

5. The adapter of claim 1 wherein further comprising a flange formed at the second open end of the tubular body for engagement with a panel to mount the adapter and one of the fiber optic and/or electrical connectors on the panel.

6. A connection system comprising:
the adapter of claim 1 ; and
a first connector configured to mate with the first open end of the tubular body.

7. The connector system of claim 6 , wherein the first connector comprises:
a connector housing having a connection axis and including lead-ins extending from an end along the connection axis at spaced apart locations around a circumference of the connector housing, a first of the lead-ins having a first dimension along the circumference of the connector housing and a second of the lead-ins having a second dimension along the circumference of the connector housing, the first dimension being greater than the second dimension so that the housing is keyed to mate in a selected rotational orientation about the connection axis; and
a connector clip assembly removably coupled within the housing;
the connector clip assembly includes at least one flexible wing wherein the flexible wing is configured to engage a recess configured as part of the lead-in.

8. The connector system of claim 7 , wherein the connector clip assembly is inserted into connector housing.

9. The connector system of claim 7 , wherein the flexible wing is a wedge shaped.

10. The connector system of claim 7 , wherein an interior surface of the housing further comprises a first cut-out and a second cut-out, the cut-outs are sized to accept a corresponding latch on an outer surface of the connector clip assembly, the cut-outs act as a key to support and to match a corresponding surface of the connector clip assembly so as to allow coupling of the connector clip assembly to the connector housing in a single orientation.

11. The connector system of claim 7 , wherein the housing includes a plurality of channels wherein lead-ins mate with a corresponding adapter recess via corresponding channels without having a line of sight to or visual sight of the lead-ins connecting or mating into adapter recesses herein called blind mating.

12. The connector system of claim 7 , wherein the connector clip assembly flexible wing is configured to engage a respective one of the lead-ins.

13. The connector system of claim 7 , wherein the connector clip assembly further comprises a plurality of optical fiber connectors wherein one of a plurality of optical fiber connectors is a LC connector or a SC connector.

14. The connector system of claim 13 , wherein the the plurality of connectors includes at least one optical fiber connector and at least one electrical connector.

15. The connector system of claim 14 , wherein the at least one optical fiber connector is one of the LC connector, the SC connector and an MPO connector, and the at least one electrical connector is one of a pin contact, an electrical socket and an RJ45 connector.

16. The connector system of claim 14 , wherein the connector clip assembly includes a protective sheath disposed around the at least one electrical connector.

17. The connector system of claim 16 , wherein the connector clip assembly is configured so as to hold the at least one optical fiber connector and the at least one electrical connector in a stacked arrangement.

18. The connector system of claim 14 , wherein the connector clip assembly further includes an in-line adapter connector clip insert comprising:
a bottom clip portion configured to hold the at least one electrical connector; and
a top clip portion disposed against the bottom clip portion so as to clamp the at least one optical fiber connector therebetween.

19. The connector system of claim 15 , wherein the connector clip insert includes a plurality of open bracket lead-ins to accept and retain at least one optical fiber connector.

20. The connector system of claim 19 , wherein the at least one optical fiber connector is an MPO connector.

21. The connector system of claim 7 , further comprising a coupling nut disposed around the connector housing.
