Abstract

A female connector member adapted to quickly couple with a male connector member includes a connector body having a fluid passageway and opening for receiving the male connector member, a slot defined in a wall of the female connector member, and a verification tab received in the slot and slidingly movable within the slot along a direction perpendicular to an axial direction in which the male connector is insertable, wherein the verification tab has an edge contoured to cause lateral movement of the verification tab from a first position in which indicia on the verification tab is concealed to a second position in which the indicia is visibly exposed when engaged by a projecting feature of the male connector member.

Claims (21)

1 . A female connector member, comprising:

a connector body defining a fluid passageway having an opening adapted to receive and connectable engage a male connector member;

a slot defined by grooves or walls of the connector body; and

a verification tab received in the slot and slidingly movable within the slot along the grooves or walls in a lateral direction perpendicular to an axial direction in which the male connector is insertable, the verification tab having an edge that is contoured to cause lateral movement of the verification tab from a first position in which the verification tab is concealed to a second position in which the verification tab is visibly exposed when engaged by a projecting feature of the male connector member during insertion of the male connector member into the opening, whereby effective coupling of the quick connecting coupling members can be verified;

wherein the connector body has a groove at an inner surface of a wall of the connector body adapted to receive and guide a protuberance projecting from the male connector member to prevent rotation of the male connector member relative to the connector body during connection.

2 . The quick connector member of claim 1 , wherein the groove has a channel-shape to receive a protuberance having a right prismatic shape.

3 . A quick connection assembly comprising the female connector member of claim 1 , and a male connector member having a projecting protuberance engageable with the groove.

4 . A female connector member, comprising:

a connector body defining a fluid passageway having an opening adapted to receive and connectably engage a male connector member;

a slot defined by grooves or walls of the connector body; and

a verification tab received in the slot and slidingly movable within the slot along the grooves or walls in a lateral direction perpendicular to an axial direction in which the male connector is insertable, the verification tab having an edge that is contoured to cause lateral movement of the verification tab from a first position in which the verification tab is concealed to a second position in which the verification tab is visibly exposed when engaged by a projecting feature of the male connector member during insertion of the male connector member into the opening, whereby effective coupling of the quick connecting coupling members can be verified wherein the contoured edge of the verification tab is straight, and at an acute angle in relation to the axial direction.

5 . The quick connector member of claim 4 , wherein the connector body is adapted to allow engagement of the verification tab with a circumferential ridge on the male connector member.

6 . A quick connection assembly comprising the female connector member of claim 5 , and a male connector member having a circumferential ridge for engaging the verification tab.

7 . A quick connection assembly comprising the female connector member of claim 6 , and a male connector member having an enlarged frustoconical section for engaging the verification tab.

8 . The quick connector member of claim 4 , wherein the angle of the straight edge of the verification tab relative to the axial direction is from 15 degrees to 60 degrees.

9 . The quick connector member of claim 4 , wherein the angle of the straight edge of the verification tab relative to the axial direction is from 40 degrees to 50 degrees.

10 . The quick connector member of claim 4 , further comprising indicia on a surface of the verification tab that is visibly displayed when the female quick connector member is effectively coupled with the male quick connector member.

11 . The quick connector member of claim 10 , wherein the indicia is a machine-readable code.

12 . The quick connector member of claim 11 , wherein the machine-readable code is a QR code or a bar code.

13 . The quick connector member of claim 10 , wherein the indicia include words, numbers and or symbols that can be read by a human.

14 . The quick connector member of claim 4 , wherein the connector body is adapted to allow engagement of the verification tab with a frustoconical section of the male connector member.
