Abstract

A connector assembly configured to sealably engage with a mating connector. The connector assembly includes a plug assembly that has a mating end configured to be inserted into the cavity of the mating connector. The connector assembly also includes a collar that surrounds the plug assembly. The connector assembly also includes a sleeve member that is positioned between the collar and the plug assembly. The sleeve member surrounds the plug assembly about the central axis and includes a plurality of fingers that extend toward the mating end. The sleeve member is stamped and formed from a common piece of sheet material. The fingers are biased away from the central axis in a flared arrangement when the collar is in the withdrawn position. The lingers press against the wall surface of the mating connector when the collar is moved from the withdrawn position to the locked position.

Claims

1. A connector assembly configured to sealably engage with a mating connector, the mating connector including a cavity and an outer wall surface, the connector assembly comprising:

a plug assembly having a loading end and a mating end and a central axis extending therebetween, the mating end configured to be inserted into the cavity of the mating connector to establish at least one of a communicative and power connection;

a collar surrounding the plug assembly about the central axis and configured to slide in an axial direction between a withdrawn position and a locked position; and

a sleeve member positioned between the collar and the plug assembly, the sleeve member surrounding the plug assembly about the central axis and comprising a plurality of fingers that extend toward the mating end, the sleeve member being stamped and formed from a common piece of sheet material, the fingers being biased away from the central axis in a flared arrangement when the collar is in the withdrawn position, wherein the fingers press against the wall surface of the mating connector when the collar is moved from the withdrawn position to the locked position.

2. The connector assembly in accordance with claim 1 wherein the sheet material has a common thickness throughout.

3. The connector assembly in accordance with claim 1 wherein the sheet material comprises a metal alloy.

4. The connector assembly in accordance with claim 1 wherein the sleeve member forms an electrical shield.

5. The connector assembly in accordance with claim 1 wherein each finger comprises a body and at least one thread element that projects radially inward from the body, the body and the at least one thread element being stamped and formed from the common piece of sheet material.

6. The connector assembly in accordance with claim 5 wherein the at least one thread element has an axial position relative to the central axis along the corresponding finger, the axial position of the at least one thread element on one finger being different from the axial position of the at least one thread element on an adjacent finger when engaged to the mating connector.

7. The connector assembly in accordance with claim 5 wherein each finger is at least partially defined between two longitudinal edges that extend substantially along the central axis, the at least one thread element including at least one ridge that extends between the two longitudinal edges, the at least one ridge being stamped and formed from the common piece of sheet material.

8. The connector assembly in accordance with claim 5 wherein the fingers are at least partially defined between two longitudinal edges that extend substantially along the central axis, the at least one thread element including a series of teeth along each longitudinal edge.

9. The connector assembly in accordance with claim 5, wherein the body of each finger includes a curved contour that curves around the central axis in a manner that substantially conforms to the outer wall surface of the mating connector.

10. The connector assembly in accordance with claim 5, wherein the sleeve member includes a base portion, the fingers extending from the base portion toward the mating end to respective distal ends, each finger being defined between inner and outer surfaces, the inner and outer surfaces along the body of each finger extending substantially parallel to the central axis when the collar is in the locked position from the base portion and to the respective distal end.

11. The connector assembly in accordance with claim 5, wherein the sleeve member includes a base portion that surrounds the plug assembly, the fingers extending from the base portion toward the mating end, the base portion extending around the central axis between separate ends that are positioned proximate to each other.

12. The connector assembly in accordance with claim 5 wherein the at least one thread element includes at least one tooth projection configured to engage the threads of the mating connector, the at least one tooth projection being stamped and formed from the common piece of sheet material.

13. The connector assembly in accordance with claim 12 wherein the fingers are at least partially defined between two longitudinal edges that extend substantially along the central axis, wherein the at least one tooth projection extends from one of the longitudinal edges and is bent radially inward.

14. A connector assembly configured to sealably engage with a mating connector, the mating connector having a cavity defined by an inner wall surface, the connector assembly comprising:

a plug body having a loading end and a mating end and a central axis extending therebetween, the mating end being configured for insertion into the cavity to establish at least one of a communicative and power connection, the plug body having an outer surface including a plurality of ramp elements that are located proximate to the mating end and project radially outward from the outer surface;

a sleeve member surrounding the outer surface of the plug body and comprising a plurality of fingers that extend toward the mating end, each finger being biased toward the central axis; and

a collar operatively coupled to the sleeve member and configured to rotate the sleeve member about the central axis when the collar is rotated between a withdrawn position and a locked position, wherein each finger engages a corresponding ramp element when the collar is rotated to the locked position, the ramp elements deflecting the fingers radially away from the central axis and pressing the fingers against the inner wall surface when the collar is rotated to the locked position.

15. The connector assembly in accordance with claim 14 wherein the sleeve member is stamped and formed from a common sheet of material.

16. The connector assembly in accordance with claim 14 wherein each ramp element includes an incline portion that first engages the corresponding finger when the sleeve member is rotated, the incline portion deflecting the corresponding finger away from the central axis when the collar is rotated about the central axis to the locked position.

17. The connector assembly in accordance with claim 14 wherein the sleeve member includes a base portion that surrounds the plug body about the central axis, each finger extending from the base portion.

18. The connector assembly in accordance claim 14 wherein the fingers have a maximum height away from the outer surface and the plug body includes a lip projecting radially outward from the outer surface and proximate to the mating end, the lip projecting a distance away from the outer surface that is greater than the maximum height of the fingers.

19. The connector assembly in accordance with claim 14 wherein each finger includes at least one thread element that projects radially outward, the at least one thread element configured to engage the inner wall surface of the mating connector when the finger is deflected away from the central axis and pressed against the inner wall surface.

20. The connector assembly in accordance with claim 19 wherein the at least one thread element has an axial position along the corresponding finger, the axial position(s) of the at least one thread element on one finger being different from the axial position(s) of the at least one thread element on an adjacent finger.
