Latching female fluid tubing coupler
A latching female tubing coupler comprises an opening, a collet finger, and an actuation member. The opening is adapted to guide a male connector along a first line of action as the male connector passes into the opening to be received within the latching female tubing coupler. The collet finger includes an engagement feature adapted to engage a coupling feature of the male connector and displace along a second line of action generally normal to the first line of action. The actuator member is adapted to displace along a third line of action generally normal to the first and second lines of action in order to disengage the engagement feature from the coupling feature of the male connector. When the engagement feature is engaged with the coupling feature on a male connector, a fluid conduit of the male connector is held in fluid communication with a fluid conduit of the latching female tubing coupler.
1. A latching female coupler for coupling fluid tubing comprising
a body defining an opening configured to receive therein a male connector, wherein the opening guides the male connector along a first line of action as the male connector is received into the opening;
an engagement feature that displaces along a second line of action that is different than the first line of action when the male connector is received in the opening and that engages the male connector to releasably couple the female connector to the male connector; and
an actuation member that displaces along a third line of action that is different than the first and second lines of action in order to disengage the engagement feature from the male connector.
2. The latching female coupler of claim 1 , wherein the actuation member further comprises a button.
3. The latching female coupler of claim 2 further comprising a housing, wherein the button is pivotally coupled to the housing.
4. The latching female coupler of claim 2 further comprising a housing substantially enclosing the engagement feature and supporting the button.
5. The latching female coupler of claim 2 further comprising
first and second biasing elements, wherein
the first biasing element acts against the engagement feature to bias the engagement feature into engagement with the male connector; and
the second biasing element acts against the button to bias the actuation member away from the engagement feature.
6. A latching female coupler for coupling fluid tubing comprising
a body defining an opening;
an engagement feature adjacent the opening;
an actuation member adjacent the engagement feature; and
a fluid conduit extending through the body from a location near the opening, wherein
insertion of a male connector in a first direction into the opening causes the engagement feature to first move in a second direction and then move in a third direction different from the second direction as the engagement feature engages the male connector,
movement of the actuation member in a fourth direction causes the engagement feature to move in the second direction to disengage from the male connector, and
each of the first direction, the second direction, the third direction, and the fourth direction is different from each of the other directions.
7. The latching female coupler of claim 6 , wherein engagement of the engagement feature with the male connector places the fluid conduit in fluid communication with the male connector.
8. The latching female coupler of claim 6 , wherein the third direction is generally opposite the second direction.
9. The latching female coupler of claim 6 , wherein the engagement feature is biased in the third direction.
10. The latching female coupler of claim 6 , wherein the actuation member is biased in a fifth direction different from the fourth direction.
11. The latching female coupler of claim 10 , wherein the engagement feature is biased in the third direction.
12. The latching female coupler of claim 6 , wherein the first and second directions are substantially perpendicular to each other.
13. The latching female coupler of claim 6 , wherein the first, and fourth directions are substantially perpendicular to each other.
14. The latching female coupler of claim 6 , wherein the first, second and fourth directions are substantially perpendicular to each other.
15. A latching female coupler for coupling fluid tubing comprising
a housing with an opening defined therein configured to receive therein a male connector in a first direction;
a fluid conduit at least partially residing within the housing;
an engagement feature including a portion adjacent the opening that engages the male connector and maintains the male connector within the opening once received therein; and
an actuation member pivotal relative to the housing, wherein
displacement of the actuation member in a second direction causes the portion of the engagement feature to move in a third direction to disengage from the male connector, thereby freeing the male connector for removal from the opening.
16. The latching female coupler of claim 15 , wherein the actuation member further comprises a pin and hinge arrangement that pivotably connects the actuation member to the housing.
17. The latching female coupler of claim 15 , wherein the actuation member includes a button that is at least partially depressible within the housing to cause the engagement feature to disengage from the male connector.
18. The latching female coupler of claim 17 , wherein the direction of movement for the portion of the engagement feature is substantially lateral to the direction of displacement for the actuation member and substantially perpendicular to the direction of depression of the button.
19. The latching female coupler of claim 15 , wherein the engagement feature comprises a collet finger.
20. The latching female coupler of claim 15 , wherein the direction of movement for the portion of the engagement feature is substantially lateral to the direction of displacement for the actuation member.
