Abstract

A plug connector includes a back shell defining a sleeve having a projection and a locking bale. A connector shell defining a collar is configured to receive the sleeve of the back shell. The collar includes an axial channel to receive the projection of the back shell and a circumferential channel coupled to the axial channel to allow rotation of the back shell relative to the connector shell. A resilient latch is located over the circumferential channel and arranged to be resiliently deflected by the bale when the back shell is rotated about the longitudinal axis between an inserted position and a locked position. The latch including a retention mechanism to retain the bale when fully rotated into the locked position.

First claim

We claim:

1. A plug connector comprising:
a back shell defining a sleeve, the sleeve comprising a projection and a bale; and
a connector shell defining a collar configured to receive the sleeve of the back shell, the collar comprising:
an axial channel to receive the projection of the back shell and a circumferential channel operative coupled to the axial channel to allow rotation of the back shell relative to the connector shell; and
a resilient latch is mounted along the circumferential channel and arranged to be resiliently deflected by the bale when the back shell is rotated about a longitudinal axis between an inserted position and a locked position, the latch including a retention mechanism to retain the bale when fully rotated into the locked position.

2. A plug connector as recited in claim 1 , wherein at least one of the back shell or the connector shell comprises a non-metallic material.

3. A plug connector as recited in claim 2 , wherein the non-metallic material is at least one of a Polycarbonate, Nylon, Polybutylene Terephthalate, or combination thereof.

4. A plug connector as recited in claim 1 , wherein at least one of the back shell or the connector shell comprises a metallic material.

5. A plug connector as recited in claim 1 , wherein the back shell further comprises a plurality of clamping tines along the circumference of the back shell opposite the sleeve and extending axially from the back shell.

6. A plug connector as recited in claim 5 , wherein the clamping times are each separated by a gap to allow independent deflection of each of the clamping tines.

7. A plug connector as recited in claim 5 , wherein at least one of the plurality of clamping times is resiliently deflectable.

8. A plug connector as recited in claim 5 , further comprising a tubular cable seal, locatable interior to the clamping tines.

9. A plug connector as recited in claim 5 , further comprising a pressure nut configured to be mounted to the back shell exterior to the clamping tines, the pressure nut comprising a reduced diameter interior surface to deflect the clamping tines inward.

10. A plug connector as recited in claim 9 , wherein the pressure nut is threadably mounted to the back shell.

11. A plug connector as recited in claim 1 , wherein the sleeve is configured to carry a plurality of electrical wire contacts.

12. A plug connector as recited in claim 1 , wherein the sleeve comprises a flange extending at least partially from the circumference of the sleeve.

13. A plug connector as recited in claim 12 , wherein the flange is configured to arrest insertion of the sleeve into the connector shell.

14. A plug connector as recited in claim 1 , wherein the latch comprises an aperture defining the retention mechanism, wherein the bale is retained by the aperture when the back shell is fully rotated into the locked position.

15. A plug connector as recited in claim 14 , wherein the aperture is a circumferential slot in the latch.

16. A plug connector as recited in claim 1 , wherein the projection contacts a wall of the axial channel in the collar to limit relative rotational movement between the back shell and the connector about the longitudinal axis.

17. A plug connector as recited in claim 1 , further comprising a shell seal disposed between an outer surface of the sleeve and an inner surface of the collar.

18. A connector comprising:
a back shell defining a sleeve, the sleeve comprising a plurality of circumferentially spaced projections and at least one bale; and
a connector shell defining a collar configured to receive the sleeve of the back shell, the collar comprising:
a plurality of circumferentially spaced axial channels to receive the plurality of projections of the sleeve of the back shell and a plurality of circumferential channels, each circumferential channel operative coupled to one of the axial channels to allow axial insertion of the collar into the sleeve and to allow rotation of the back shell relative to the connector shell about a longitudinal axis; and
a resilient latch is mounted along at least one of the circumferential channels, the latch being arranged to be resiliently deflected by the bale when the back shell is rotated about a longitudinal axis toward a locked position, wherein the latch comprises a retention mechanism to retain the bale when fully rotated into the locked position.

19. A connector as recited in claim 18 , wherein the sleeve comprises a flange extending at least partially from the circumference of the sleeve.

20. A connector as recited in claim 19 , wherein the flange is located to limit insertion of the sleeve into the connector shell.

21. A connector as recited in claim 18 , wherein the retention mechanism comprises a circumferential slot, and wherein the bale is retained by the slot when the back shell is fully rotated into the locked position.

22. A connector as recited in claim 18 , wherein at least one of the projection contacts an inner wall of at least one of the axial channels in the collar to limit relative rotational movement between the back shell and the connector about the longitudinal axis.
