Abstract
Provided is a quick connector assembly for joining a male member and a female connector member together to secure fluid communication in a fluid line system. The quick connector assembly includes a primary latch and a secondary latch configured to toggle between engaged and disengaged positions and to allow for a visual, audible, and/or tactile indication as to the status of a secure attachment between a male member and a female connector member.
Claims17
A quick connector assembly comprising:
- a tubular housing, defining a lumen extending along an axis, having:
- a first open end with a larger inner diameter than an opposing second open end, a slot passing through a sidewall of the housing, and a shoulder on an inner facing of the lumen;
- a retaining sleeve, coaxially received within the housing and conforming to the housing to define a portion of the lumen, having:
- a base seated on the shoulder, a axially compressible, biasing midsection extending toward the first open end, and an upper abutment including a blocking member;
- and
- a latching assembly, seated in the slot, having:
- a body defining a central aperture, a primary latching mechanism, and a secondary latching mechanism including a slidable member, wherein the central aperture and the primary latching mechanism each conform to the housing to define a section of the lumen and wherein the slidable member selectively translates through the slot to engage the blocking member when the biasing midsection is compressed.
