Redundant Latch/Verifier For a Quick Connector

by:Yober     2020-05-26
Quick connector coupling comprising a connector body, a tubular male member through having an upset, a primary retainer and a separate redundant latch/verifier. The connector body defines a through bore and the male organ extends into the bore. The primary retainer releasably secures the male member within the connector body. The redundant latch/verifier is releasably coupled to the connector body and movable between an unlatched position and a latched position. It includes spaced apart fingers with verifying tabs that permit movement to the latched position only after full insertion of your male member. The fingers have release tabs to manually spread the extension beams. In another form, the connector body includes locking pads extending radially inward. The legs of the primary retainer are located inward of the locking pads preventing the legs from moving to a released position if said male member is pulled in a direction to take it off from the connector body. In automotive and other fields, quick connector couplings, which generally include a male member received and sealingly retained in unique connector body, occasionally utilize to provide a fluid connection between two components or conduits, thusestablishing a fluid line inside the two components. Involving quick connector couplings is advantageous on that a sealed and secured fluid line may be established with a minimum amount of time and expense. A number of methods and mechanisms exist for securing the male member and female connector body of a short connector coupling collectively. One type of retention mechanism involves use of a retainer in the design of a retention lip inserted through slots formed an exterior of the connector body. Beams extending through the slots are poised between the male member upset and therearward surfaces defining the slots, thereby preventing disconnection of the coupling. Due to the physical appearance of such retainers, they are referred to typically the trade as 'horseshoe' retainers. An sort of this type of retainer is published on U.S. Pat. An absense of. 5,586,792, to Kalahassthy et 's., which is herein incorporated by reference. The 'horseshoe' retainer, disclosed in the '792 patent, permits easy release within the coupling without significantly increasing the complexity of the coupling. Application for U.S. Ser. Never a. 11/087,358 filed Mar. 23, 2005 disclosed various arrangements of connectors with horseshoe type retainers and a redundant latch/verifier. The disclosure of that application is incorporated by reference herein. The quick connector coupling of present invention is some other of the kind of connector disclosed typically the '792 patent and also the application Ser. Basically no. 11/087,358. The arrangement of modern day invention provides the advantages that onassembly with the quick connector coupling, the redundant latch/verifier cannot be chosen its latched position unless the associated tube is in the fully inserted job position. Its position thereby provides a physical and visual indication that the tube isnot fully placed. The arrangement of the present invention also increases the benefit that the legs of the primary retainer cannot be accidentally moved their particular locked position back to their unlocked position if your male member is pull in the forwarddirection relative to the connector body thereafter the male member is twisted or rotated around its axis. Once placed in latched position, the redundant latch/verifier prevents unintentional release of the tube by complications retainer. The redundant latch/verifier is also able to independently retain the male organ of the tube in the connectorbody should the primary retainer fail. As with the arrangement of the primary retainer and the redundant latch/verify with the quick connector coupling, the arrangement for the primary retainer and also the redundant latch/verifier of your alternative quick connectorcoupling, namely locating the verifying tab in the redundant latch/verifier immediately axially rearward for this legs of the primary retainer, assures that the fingers of the redundant latch/verifier are merely able spreadoutward after the upset has completely passed the legs of the primary retainer.
