Definitions

  • the present invention relates generally to connectors for fluid lines, and more particularly relates to quick connector couplings for forming a severable connection in a fluid line between a male member and a female member.
  • quick connector couplings which generally include a male member received and sealingly retained in a single piece plastic or metal female connector body having a stem portion formed integral with a retainer housing portion, are often utilized to provide a fluid connection between two components or conduits, thus establishing a fluid line between the two components.
  • Use of quick connector couplings is advantageous in that a sealed and secured fluid line may be established with a minimum amount of time and expense.
  • One type of retention mechanism involves use of a retainer in the form of a retention clip inserted through slots formed in the exterior of the connector body. Beams extending through the slots are poised between the male member upset and the rearward surfaces defining the slots, thereby preventing disconnection of the coupling. Due to the physical appearance of such retainers, they are referred to in the trade as“horseshoe” retainers.
  • An example of this type of retainer is found in U.S. Pat. No. 5,586,792, to Kalahasthy et al., which is herein incorporated by reference.
  • the “horseshoe” retainer, disclosed in the 792 patent permits easy release of the coupling without significantly increasing the complexity of the coupling.
  • quick connector coupling of the present disclosure provides the benefits of only requiring access from one side (e.g. top, bottom, left or right) in order to operate the components of the coupling and connect the fluid lines. Further, since the quick connector coupling of the present disclosure can be coupled to the male and female components in any radial direction, the quick connector can be oriented to provide the most convenient access for the operator.

The second pair of arms have a latch engaged with the retainer housing in an initial configuration of the quick connecter coupling such that the verifier cannot slide relative to the connector body.
  • each leg of the first and second pair of legs is sized and positioned to be engaged by the upset and moved radially outwardly thereby as the male member is inserted into the retainer housing.
  • the second pair of legs of the retainer are sized and positioned relative to the second pair of arms of the verifier such that outward movement of the second pair of legs causes radially outward movement of the second pair of arms to disengage the latch from the retainer housing and permit sliding of the verifier relative to the retainer housing.
  • the verifier can serve as a redundant or secondary latch, and also provide visual indication that the male member is securely retained in the quick connector coupling and the fluid line is formed with the female member.
  • the quick connector coupling has an intermediate configuration where the male member is inserted into the second through bore such that the first pair of legs are on a male side of the upset, and the upset is engaged with the second pair of legs such that the second pair of legs are moved radially outward.
  • the quick connector coupling has a verified configuration where the verifier has slid relative to the retainer housing and the second pair of arm have moved radially inwardly such that the latch engages the retainer housing.
  • the first pair of arms are sized and positioned in the verified configuration to limit outward movement of the first pair of legs of the retainer such that the male member cannot be removed from the quick connector coupling.

  • the verifier is slidable in an axial direction relative to the connector body and the retainer housing, wherein the verifier slides axially between the initial configuration and the verified configuration.

  • the verifier 38 is also generally defined by an annular body 70 defining a large hole 71 that is sized to be fit over and around the cylindrical exterior surface of the connection body 32. Due to the annular shape of the body 70, it may be grasped from a side of the quick connector coupling 30 corresponding to the retainer 36, and thus the coupling 30 only required physically access from one side of the device. At the same time, the annular shaped body 70 may also be grasped from any side of the coupling 30 as needed or desired.

  • the stem 35 of the connection body 32 may be connected to the female member 22 in a generally permanent manner via methods known by those skilled in the art.

  • continued axial movement of the male member 20 causes the upset 24 to engage the chamfered surface 61 of the second pair of legs 54. This in turn causes laterally outward movement of the second pair of legs 54.
  • the verifier 38 is initially positioned toward the female member 22 (i.e., up on the page in FIG. 8) while its second pair of arms 74 extend axially into engagement with the retainer housing 34.

  • the end surface of the latch 78 (and hence the second pair of arms 74) is also engaged with the exterior surface of the second pair of legs 54 within the slot 48.
  • the outward movement of the second pair of legs 54 (caused by the upset 24 of the male member 20) thus causes corresponding laterally outward movement of the second pair of arms 74 and their latches 78.
  • the relative sizes of the upset 24, the second pair of legs 54 (and in particular the lateral width of the second portion 60) and the lateral width of the latches 78 of the second pair of arms 74, are constructed so that the latches 78 are freed from the lateral slots 48 and the peripheral rim 65 of the retainer housing 34. This is also seen in the front view of FIG.
  • FIG. 1 1 also shows that a back wall of the annular body 62 adjacent the female end 68 and peripheral rim 65 prevent further axial movement of the male member 20 towards the female member 22. That is, when the male member 20 is fully inserted into the through bores 42,44 of the quick connector coupling 30, the annular upset 24 remains in engagement with the second pair of legs 54 to keep them deflected radially outwardly.
  • the verifier 38 may be slid axially towards the male member 20 (down on the page) as illustrated by FIG. 12.
  • the latches 78 can thus slide along the exterior surface of the retainer housing 34 until it reaches the axially facing surface of the annular member 62 on the male side 66 thereof.
  • FIG. 15 shows a front view of the second pair of arms 74 and its latches 78 having moved again laterally inwardly into engagement with the retainer housing 34.
  • first pair of arms 72 of the verifier 38 have reached a point where they axially overlap the first pair of legs 52 of the verifier 36.
  • first pair of legs 52 are captured on the male side (down on the page) of the upset 24, thereby preventing the male member 20 from being retracted axially or removed from the quick connector coupling 30.
  • the annular body 62 of the retainer housing 34 engages with and supports the first pair of arms 72 to prevent outward deflection of the first pair of legs 52.
  • the second pair of arms 74 and its latches 78 must be manually forced laterally and radially outwardly to free the latches 78 from the engagement surface 67 on the retainer housing 34, whereby the verifier 38 may be again slid towards the female member 22 (up on the page).
  • the first pair of legs 52 of the retainer 36 will generally prevent withdrawal of the male member 20 until the verifier is moved axially, and hence the first pair of legs 52 mush also be manually forced radially outwardly in order to free the male member.
  • the verifier 38 also serves as a redundant or secondary latch of the quick connector coupling 30 forming a fluid line between the male member 20 and female member 22.
