Rapid-connect coupler and receptacle having anti-rotation feature
A rapid-connect coupler having an anti-rotation feature is disclosed. A coupler includes a housing, a probe configured to translate longitudinally within the housing, a ball cage, a plurality of balls disposed in the ball cage, and a slidable sleeve coupled to the probe and configured to translate longitudinally with the probe. The slidable sleeve includes a collar that defines a plurality of channels positioned radially about and extending axially along an outer surface. The plurality of channels of the collar are configured to receive bearings of the receptacle to prevent rotation of the coupler relative to the receptacle. To couple the coupler to the receptacle, the slidable sleeve is configured to slide in a longitudinal direction into the receptacle to cause the plurality of channels to receive the bearings of the receptacle and subsequently cause the plurality of balls to lock the coupler to the receptacle.

wherein, to couple the coupler to the receptacle, the slidable sleeve is configured to slide in a longitudinal direction into the receptacle to cause the plurality of channels to receive the bearings of the receptacle and subsequently cause the plurality of balls to lock the coupler to the receptacle.
2. The coupler of claim 1 , wherein each of the plurality of channels is configured to prevent a respective one of the bearings of the receptacle from sliding out a back of the plurality of channels and off the back end of the slidable sleeve.
3. The coupler of claim 1 , wherein the collar includes a back wall that prevents the bearings from sliding out a back of the plurality of channels and off the back end of the collar.
4. The coupler of claim 1 , wherein each of the plurality of channels has an axial length extending along the outer surface of the collar that prevents the bearings from sliding out a back of the plurality of channels and off the back end of the collar.
5. The coupler of claim 1 , wherein each of the plurality of channels is formed by two walls configured to form a close fit around a respective one of the bearings coupled thereto.
6. The coupler of claim 1 , wherein the plurality of channels are equidistant from each other along an outer circumference of the collar.
7. The coupler of claim 1 , wherein the plurality of channels are recessed from the outer surface of the collar.
8. The coupler of claim 1 , wherein the ball cage defines a plurality of ball slots, and wherein each of the plurality of balls is disposed in a respective one of the plurality of ball slots.
9. The coupler of claim 8 , wherein, in the decoupled position, the plurality of balls are configured to be pushed radially outward by a lip of the receptacle as the coupler receives the receptacle and return radially inward into a recess of the receptacle behind the lip once the lip is translated past the plurality of balls.
10. The coupler of claim 9 , wherein, to subsequently transition to the coupled position, the slidable sleeve is configured to slide over the plurality of ball slots to lock the plurality of balls in the recess of the receptacle to couple the coupler to the receptacle.
11. A coupler for connecting a tank to a receptacle, the coupler comprising:
a housing;
a probe configured to translate longitudinally within the housing;
a handle assembly configured to cause the probe to translate within the housing;
a ball cage;
a plurality of balls disposed in the ball cage; and
a slidable sleeve coupled to the probe and configured to translate longitudinally with the probe, wherein the slidable sleeve includes:
a coupling end; and
a collar adjacent to the coupling end, wherein the collar includes an outer surface and a back end, wherein the collar defines a plurality of channels that are positioned radially about and extend axially along the outer surface, wherein the plurality of channels of the collar are configured to receive bearings of the receptacle to prevent rotation of the coupler relative to the receptacle;
wherein, to couple the coupler to the receptacle, the slidable sleeve is configured to slide in a longitudinal direction into the receptacle to cause the plurality of channels to receive the bearings of the receptacle and subsequently cause the plurality of balls to lock the coupler to the receptacle.
12. The coupler of claim 11 , wherein each of the plurality of channels is configured to prevent a respective one of the bearings of the receptacle from sliding out a back of the plurality of channels and off the back end of the collar.
13. The coupler of claim 11 , wherein the collar includes a back wall that prevents the bearings from sliding out a back of the plurality of channels and off the back end of the collar.
14. The coupler of claim 11 , wherein each of the plurality of channels has an axial length extending along the outer surface of the collar that prevents the bearings from sliding out a back of the plurality of channels and off the back end of the collar.
15. The coupler of claim 11 , wherein each of the plurality of channels is formed by two walls configured to form a close fit around a respective one of the bearings coupled thereto.
16. The coupler of claim 11 , wherein the plurality of channels are equidistant from each other along an outer circumference of the collar.
17. The coupler of claim 11 , wherein the plurality of channels are recessed from the outer surface of the collar.
18. The coupler of claim 11 , wherein the ball cage defines a plurality of ball slots, and wherein each of the plurality of balls is disposed in a respective one of the plurality of ball slots.
19. The coupler of claim 18 , wherein the plurality of balls are configured to be pushed radially outward by a lip of the receptacle as the coupler receives the receptacle and return radially inward into a recess of the receptacle behind the lip once the lip is translated past the plurality of balls.
20. The coupler of claim 19 , wherein the slidable sleeve is configured to subsequently slide over the plurality of ball slots to lock the plurality of balls in the recess of the receptacle to couple the coupler to the receptacle.
