    Cross Reference to Related Order
    [0001] This order claims the benefit of United States Interim Order No. 62/103,117, filed January 14, 2015. The full disclosure of the above application is incorporated herein by reference. Field of Invention
    [0002] The present disclosure relates to quick connectors and more particularly to a quick conduit connector with a primary and secondary latch retainer. Background of the Invention
    [0003] Quick connectors or snap connectors are used in a wide variety of applications, particularly for joining fluid transport conduits in industrial and automotive applications. Typically, a retainer is mounted on a frame of the female portion of the connector. A male fitting is inserted into the frame and secured by a retainer. In order to improve retention of the male fitting, a secondary retainer is provided. In addition, various types of seals and seal retainers are positioned within the female frame to seal the male fitting against leakage.
    [0004] Several types of quick connectors exist with primary and secondary retaining latches. While such quick connectors provide satisfactory connections, those skilled in the art are always striving to improve. Additionally, these quick connectors provide an indicator to provide the user with a visual indication that positive lock has occurred. These indicators generally protrude from the frame to provide the user with assurance that the first and second latch have been properly locked to keep the male and female parts of the connector together.
    [0005] The present disclosure provides the technique with a quick connector having a primary and secondary latch retainer with a visual indicator. The visual indicator reveals that the male conduit is properly locked into the female frame. The present disclosure provides a primary and secondary latch retainer that mesh with each other to enclose a depression in the male mating portion of the connection. Additionally, the present disclosure provides a visual indicator on the second lock retainer that is adjacent to a push button for releasing the first lock retainer. This allows release of the male fitting from the female frame by pressing the visual indicator and release push button from substantially the same position without the user having to move their hand. Invention Summary
    [0006] According to the disclosure, a quick conduit connector comprises a frame having a latch retainer receiving end and a socket. A center hole, defining an axis, extends through the frame. A primary lock retainer is positioned on the lock retainer receiving end of the frame. The primary latch retainer includes a push-button base, a guide member, and a conduit receiving member. The conduit receiving member includes a pair of arms extending from the base. The pair of arms defines an elliptical opening with a slit between the distal ends of the arms. The guiding member secures the primary lock retainer with the lock retainer receiving end of the frame. A secondary lock retainer is positioned at the conduit receiving end of the frame. The secondary lock retainer includes a base, a verification mechanism, and the retaining member. The verification mechanism extends from the base and includes a pair of columns and a sliding member. The sliding member includes an opening to allow passage of a male conduit at the conduit receiving end of the frame. In an unlocked position, the pair of columns is blocked by the frame prohibiting entry of the retaining member into the center hole shaft. In a locked position, an enlarged annular conduit entering the frame expands the columns to allow the second lock retaining member to enter the frame in the axis direction. A portion of the sliding member protrudes beyond the frame to indicate a locked position. The second lock retainer member inserts into the slot between the arms of the first lock retainer in the locked position. The arms of the first lock retainer move transverse to the hole axis to allow the male conduit fitting to lock with the first lock retainer. The sliding member of the second lock retainer is positioned in a channel in the frame. A conical surface exists on the arms of the first retainer. The base of the first lock retainer acts as a push button to release the male conduit fitting from the locked position. The first lock retainer guiding member is guided in a channel in the frame. The channel includes a tapered surface that, upon contact, orients the guide member. When force is removed from the first lock base, the tapered surfaces return the first lock retainer to its home position. The portion of the sliding member extending from the frame is forced towards the frame to unlock the second lock retainer. The first lock retainer push-button base and the second lock retainer portion of the sliding member extend from the structure adjacent to each other.
    [0007] According to a second object of the invention, a quick conduit connector comprises a structure with a latch retainer receiving end and a socket. A center hole, defining an axis, extends through the frame. A primary lock retainer is positioned on the lock retainer receiving end of the frame. The primary latch retainer includes a push-button base, a guide member, and a conduit receiving member. The conduit receiving member includes a pair of arms extending from the base. The pair of arms defines an elliptical opening with a slit between the distal ends of the arms. The guiding member secures the primary lock retainer within the lock retainer receiving end of the frame. A secondary lock retainer includes a base, a verification mechanism, and a retaining member. The scan engine extends from the base and includes a visual indicator. In an unlocked position, the visual indicator is placed on the frame. In the locked position, the visual indicator extends from the frame. The visual indicator is adjacent to the base of the first lock retainer push button. Therefore, to release the male conduit connector from the frame, a force is applied to the visual indicator and pushbutton in the same direction. The visual indicator and push button are aligned close to each other in the unlocked position. Visual indicator and push button are on the same side of the frame. The visual indicator touches the push button. When the user returns the visual indicator to the unlocked position, the user can immediately press the push button to release the conduit fitting. This allows the release of the male conduit from the frame without the user repositioning their hand. The latch retainer receiving end of the frame includes a pair of opposing walls separated by the center hole. An opening exists between one end of the pair of opposite walls. The visual indicator and push button are positioned in the opening.

    [0022] Exemplary embodiments will now be described in more detail with reference to the accompanying drawings.
    [0023] Referring to the figures, a conduit quick connector assembly is illustrated and shown with reference numeral 100. The assembly includes a frame 102 connected to conduit 104 and a male conduit 106. The male conduit 106 includes an end of housing 108 and a depression 110. Structure 102 includes a latch retainer receiving end 112 and a housing 114 that is mated with conduit 104. Housing 114 generally includes a plurality of annular ribs or grooves 116 to aid in mating with conduit 104. conduit 104. Also, a seal 118 may be positioned on the fitting 114 in an annular recess 120 to improve the seal between the fitting and the conduit 104. A fastening bracket (not shown) may be positioned over the conduit 104 and fitting 114 to lock them together.
    [0024] The latch retainer receiving end 112 houses a primary latch retainer 122 and the secondary latch retainer 124. The frame 102 including the latch retainer receiving ends 112 and socket 114 defines a central through hole 126. Central through hole 126 extends through frame 102 and defines a longitudinal axis 128. Latch retainer receiving end 112 includes a pair of opposing walls 130, 132. A partition 134 extends between walls 130, 132. The partition 134 includes an opening aligned along with the center hole 126. Opposite walls 130, 132 include a rear wall 136 which acts as a gusset to connect opposing walls 130, 132 together and socket 114. 136 also defines an opening to allow socket 108 to pass through rear wall 136. An enlarged cylindrical portion 138 is connected to rear wall 136 leading to socket 114. 138 houses seals 140, 142, spacer 144 and fastener 146. These elements seal male fitting 108 within frame 102.
    [0025] The free ends of walls 130, 132 include internally angled tapered flanges 148, 150. Channels 152, 154 are formed between flanges 148, 150 and split 134. Channels 152, 154 receive the primary lock retainers and secondary 122, 124 as will be explained in this document. Apertures 156, 158 are formed between opposing walls 130, 132 at opposite ends of the walls. In this way, the openings 156, 158 are opposite each other.
    Channels 152, 154 include tapered walls 160, 162. Rear wall 136 includes detents 164, 166, 168, 170. Detents 164, 166, 168, 170 include a curved surface 172 and a wedge 174. A second channel 176 is formed between partition 134 and back wall 136.
    [0027] The first retainer or primary latch 122 includes a push-button base 180 connected to a guide member 182 and a conduit receiving member 184. The guide member 182 extends from one end of the push-button base. pressure 180. Guide member 182 has a general horseshoe shape. It includes a pair of columns 186, 188 with notches 190 on the free ends of columns 186, 188. Notches 190 include a curved outer surface 192 that contacts curved conical surfaces 160, 162. Curved surfaces 192 extend across the surface curved conical 160, 162 as illustrated in figure 7.
    [0028] Conduit receiving member 184 includes a pair of arms 194, 196 extending from the other end of push-button base 180. The arms include a slit 198 at their free distal end. Arms 194, 196 are connected at their distal end by a support plate 200. Slot 198 is defined by support plate 200 and arm surfaces 202, 204. In this way, an open channel is formed between arms 194, 196.
    The arms 194, 196 include tapered surfaces 206, 208. The tapered surfaces 206, 208 urge the male socket 108 into the frame 102. The arms 194, 196 define an elliptical opening 210 that allows the passage of the male socket 108. A spacer portion 185 is adjacent to rear wall 136. As male fitting 108 enters conduit receiving member 184, tapered surfaces 206, 208 contact enlarged annular depression 110. This moves first retaining latch 122, push-button 180, in a first direction to the axis 128 and one of the end openings of the walls 130, 132. When this occurs, orientation occurs between the notches 190 as the guiding member 182 moves against the curved conical surfaces 160, 162 After the depression 110 passes the conduit receiving member 184, the first retaining latch 122 moves in an opposite direction away from the axis 128. This is due to the force of the tapered surfaces 160, 162 forcing the columns of m hello 186, 188 in the opposite direction. In addition, the notches 190, due to the protrusion 212, 214 formed in the channel 152, 154, retain the first lock retainer 122 at the lock retainer end 112. The conduit receiving member of the first lock retainer 184 is positioned on the second channel between partition 134 and back wall 136. Additionally, partition 134 includes a tapered surface 216 adjacent the opening that enhances insertion of depression 110 and slot 108 into frame 102 and through first latch retainer 122.
    The second retainer or secondary latch 124 includes a base 250, a verification mechanism 252 and a retainer member 254. The base 250 has an arcuate outer surface that is curved to provide a continuous appearance with the outer surface of the structure in the locked position. Verification mechanism 252 includes a pair of columns 256, 258 and a sliding member 260. The columns include detents 262, 264, 266, 268. These detents mesh with detents 164, 166, 168 and 170 to hold the latch retainer in an unlocked position as illustrated in Figure 8. Further, the free ends of the columns include tapered surfaces 270 that enhance entry of the socket depression 110 108 into a retained position as illustrated in Figure 9.
    [0031] The sliding member 260 has an elliptical opening 280 and a visual indicator 282. The elliptical opening 280 allows passage of the insert 108 through the slide 260. The slide 260 fits the channels 152, 154 at the latch retainer receiving end 112 of frame 102. Posts 256, 258 fit into the second channel between rear wall 136, conduit receiving member 184, and spacer portion 185 of first retaining latch 122.
    [0032] The connector assembly is illustrated in figure 1 in the unlocked position. In order to lock conduit 106 with frame 102, the following occurs. Conduit 106 with fitting 108 enters sliding member opening 280. Fitting of conduit 108 continues through the opening of the partition behind guide member 182 toward the retaining member of the first retaining latch 184. The depression 110 contacts the tapered surface at split 134 to center it along the axis. Depression 110 continues in frame 102 toward socket 114 and contacts first latch retaining member 184. As this occurs, tapered surfaces 206, 208 in retaining member 184 contact depression 110. Conduit 106 continues to be pushed. into frame 102. Retaining member 184 moves in a first direction away from axis 128. Due to support plate 200 holding arms 194, 196 together, no lateral movement of arms 194, 186 occurs. This allows transverse movement of the first locking retainer 122 away from the axis 128. The depression 110 passes the retaining member 184 and moves in the area defined by the spacer portion 185 of the first retainer 122 between the retaining member 184 and the rear wall. 136. As this occurs, depression 110 contacts columns 256, 258 of second latch retainer 122. Conical surfaces 270 allow columns 256, 258 to move apart from each other. As this occurs, detents 262, 264, 266, 268 move out of contact with detents 164, 166, 168, and 170. In this way, arms 256, 258 are positioned along the circumferential surface of depression 110. The second latch retainer 124 can now move in the direction of axis 128 of frame 102. As this occurs, retainer member 254 is positioned within slot 200 between surfaces 202, 204 of the extending ends of arms 182, 184. second lock retainer member 254, as well as first lock retainer member 184, is positioned adjacent to the smaller diameter portion of conduit 106 blocking depression 110 from exiting frame 102. Also, as this occurs, the visual indicator 182 protrudes beyond the surface of the lock retainer receiving end 112. In this way, the user can easily see that the first 122 and second 124 lock retainers are in a locked position.
    [0033] In order to release conduit 106 from frame 102, a force is applied to visual indicator 282 transversely to axis 128. Visual indicator 282, immediately adjacent to push-button base 180, moves toward axis 128 of frame 102. Since the end of the visual indicator 182 is flush with the push-button base 180 and continuous in appearance with the frame walls 130, 132, the push-button base 180 can be moved in the direction of the axis 128 of the frame 102. This moves the elliptical opening toward alignment with the axis 128. This allows the conduit 106 to be withdrawn from the frame, since the opening in the retainer 184 is large enough to allow the depression 110 to be removed through of the elliptical opening of the first latch retainer 122. Further, as this occurs, the guide member 182 and notches 190 contact the arcuate tapered surfaces 156, 158. The tapered surfaces force the guide member as well as the first latch retainer 122 back to its home position.
