Abstract

Means 1 in the form of a cover for a connector assembly 86, a skirt 2'"'"' of the cover encircling a front end 4 of the connector assembly 86, connecting means 7 for connecting the cover to the connector assembly 86 when the skirt 2'"'"' is removed from the front end 4, internal webs 9, 9 of the cover lodged in a gap 29 in the front end 4 to retaini the cover on the front end 4, and pockets 11, 11, 11 external to the skirt 2'"'"' frictionally receiving the keying elements 94, 94'"'"', 94" in the absence of any one of the keying elements 94, 94'"'"', 94" in the connector assembly 86.

Claims

1. A connector assembly comprising:

an optical fiber connector, a keying element receiving passage in the connector, the connector being adapted with keying elements for use one at a time in the passage, and means applied to the connector for keeping the keying elements with the connector assembly while they are not being used in the passage.

2. A connector assembly as recited in claim 1, wherein the improvement comprises:

said means includes a cover for the connector assembly, a skirt of the cover encircling a front end of the connector, connecting means for connecting the cover to the connector when the skirt is removed from the front end, internal webs across of the cover lodged in a gap in the front end to retain the cover on the front end, and pockets external to the skirt frictionally receiving the keying elements, whereby all of the keying elements that are interchangeable with one another are retained in the cover in the absence of any one of the keying elements in the passage.

3. A connector assembly as recited in claim 2, wherein the connecting means comprises;

a lanyard unitary with the skirt, a loop at a free end of the lanyard encircling a rear of the connector, and a nut larger in circumference than the circumference of the loop, the nut being connected to a rear of the connector and engaged against the loop.

4. A connector assembly as recited in claim 2, comprising;

the connector has an axially extending channel in an external surface, the gap intersects sides of the channel, and the webs extend along the channel and frictionally engage sides of the channel to retain the cover on the connector.

5. A connector assembly as recited in claim 1, wherein the connector has an axially extending channel in an external surface, sides of the channel extend to the front end of the connector and have outwardly flared portions at the front end of the connector, and the webs are freely inserted between the outwardly flared portions and are funneled along the channel by the outwardly flared portions.

6. A connector assembly as recited in claim 2, wherein a cross section profile of the front end of the connector is asymmetrical, the connector has a symmetrical cross section profile rearward of the front end, and the skirt extends to encircle the asymmetrical cross section profile and the symmetrical cross section profile.

7. A connector assembly as recited in claim 3, comprising;

the connector has an axially extending channel in an external surface, the gap intersects sides of the channel, and the webs extend along the channel to retain the cover on the connector.

8. A connector assembly as recited in claim 2, wherein the connector has an axially extending channel in an external surface, sides of the channel extend to the front end of the connector and have outwardly flared portions at the front end of the connector, and the webs are freely inserted between the outwardly flared portions and are funnelled along the channel by the outwardly flared portions.

9. A connector assembly as recited in claim 3, wherein the connector has an axially extending channel in an external surface, sides of the channel extend to the front end of the connector and have outwardly flared portions at the front end of the connector, and the webs are freely inserted between the outwardly flared portions and are funnelled along the channel by the outwardly flared portions.

10. A connector assembly as recited in claim 4, wherein the sides of the channel extend to the front end of the connector and have outwardly flared portions at the front end of the connector, and the webs are freely inserted between the outwardly flared portions and are funnelled along the channel by the outwardly flared portions.

11. A connector assembly as recited in claim 2, wherein a cross section profile of the front end of the connector is asymmetrical, the connector has a symmetrical cross section profile rearward of the front end, and the skirt extends to encircle the asymmetrical cross section profile and the symmetrical cross section profile.

12. A connector assembly as recited in claim 3, wherein cross section profile of the front end of the connector is asymmetrical, the connector has a symmetrical cross section profile rearward of the front end, and the skirt extends to encircle the asymmetrical cross section profile and the symmetrical cross section profile.

13. A connector assembly as recited in claim 4, wherein a cross section profile of the front end of the connector is asymmetrical, the connector has a symmetrical cross section profile rearward of the front end, and the skirt extends to encircle the asymmetrical cross section profile and the symmetrical cross section profile.

14. A connector assembly as recited in claim 5, wherein a cross section profile of the front end of the connector is asymmetrical, the connector has a symmetrical cross section profile rearward of the front end, and the skirt extends to encircle the asymmetrical cross section profile and the symmetrical cross section profile.
