Abstract

A latching connector receptacle includes a receptacle body configured to receive a plug, a biased release ring coupled to the receptacle body, and a latch dog assembly coupled to the receptacle body. The latch dog assembly includes a moveable latch dog configured to matingly engage the plug and matingly engage the release ring, and a moveable latch indicator configured to move in response to movement of the latch dog.

First claim

What is claimed is:

1. A latching connector receptacle comprising:
a receptacle body configured to receive a plug;
a biased release ring coupled to the receptacle body; and
a latch dog assembly coupled to the receptacle body, the latch dog assembly comprising:
a moveable latch dog configured to matingly engage the plug, and matingly engage the release ring; and
a moveable latch indicator configured to move in response to movement of the latch dog;
further comprising a latch indicator band coupled to a first latch indicator, wherein the latch indicator band extends radially around the latch dog assembly, and wherein a first latch amplification portion of the latch indicator band causes displacement of the first latch indicator in response to an increase in tension of the latch indicator band;
wherein a second latch amplification portion of the latch indicator band causes displacement of a second latch indicator coupled to the latch indicator band in response to an increase in tension of the latch indicator band, and wherein the displacement of the second latch indicator is in a different direction than the displacement of the first latch indicator.

2. The latching connector receptacle of claim 1 wherein:
the latch dog is configured to be urged radially outward in response to engagement with a surface of the plug; and
the latch indicator band is placed under increased tension in response to the latch dog being urged radially outward.

3. The latching connector receptacle of claim 1 wherein the latch indicator band is under an increased tension during a mating procedure and during a release procedure.

4. The latching connector receptacle of claim 3 wherein:
during the mating procedure, the latch dog is urged radially outward in response to engagement with the surface of the plug; and
during the release procedure, the latch dog is urged radially outward in response to engagement between the release ring and an interior profile of the latch dog.

5. The latching connector receptacle of claim 1 wherein axial displacement of the release ring away from the plug causes the release ring to engage an interior profile of the latch dog, which urges the latch dog radially outward and out of engagement with a lip of the plug.

6. The latching connector receptacle of claim 5 wherein the release ring is biased toward the plug by a spring such that a force required for axial displacement of the release ring is greater than a spring force of the spring.

7. The latching connector receptacle of claim 5 wherein a pull force applied to a mounting assembly of the release ring causes axial displacement of the release ring away from the plug.

8. A latching connector receptacle comprising:
a receptacle body configured to receive a plug;
a moveable latch dog coupled to the receptacle body; and
a biased release ring slidably coupled to the receptacle body, the release ring comprising:
an end portion configured to slidably engage the moveable latch dog; and
a biasing mechanism configured to maintain engagement between the end portion and the latch dog;
wherein axial displacement of the release ring away from the plug causes the release ring to engage an interior profile of the latch dog, which urges the latch dog radially outward and out of engagement with the lip of the plug.

9. The latching connector receptacle of claim 8 wherein the biasing mechanism comprises a spring such that a force required for axial displacement of the release ring is greater than a spring force of the spring.

10. The latching connector receptacle of claim 8 wherein a pull force applied to a mounting assembly of the release ring causes axial displacement of the release ring away from the plug.

11. A latching connector receptacle comprising:
a receptacle body configured to receive a plug;
a moveable latch dog coupled to the receptacle body, the moveable latch dog configured to slidably engage the plug; and
a moveable latch indicator coupled to the receptacle body, the latch indicator moveable in response to slidable engagement of the latch dog with the plug;
further comprising a latch indicator band coupled to a first latch indicator, wherein the latch indicator band extends radially around the latch dog, and wherein a first latch amplification portion of the latch indicator band causes displacement of the first latch indicator in response to an increase in tension of the latch indicator band;
wherein a second latch amplification portion of the latch indicator band causes displacement of a second latch indicator coupled to the latch indicator band in response to an increase in tension of the latch indicator band, and wherein the displacement of the second latch indicator is in a different direction than the displacement of the first latch indicator.

12. The latching connector receptacle of claim 11 wherein:
the latch dog is configured to be urged radially outward in response to engagement with a surface of the plug; and
the latch indicator band is placed under increased tension in response to the latch dog being urged radially outward.

13. The latching connector receptacle of claim 11 wherein the latch indicator band is under an increased tension during a mating procedure and during a release procedure.

14. The latching connector receptacle of claim 13 wherein:
during the mating procedure, the latch dog is urged radially outward in response to engagement with the surface of the plug; and
during the release procedure, the latch dog is urged radially outward in response to engagement between a release ring and an interior profile of the latch dog.
