Description

QUICK CONNECTOR WITH ONE-PIECE RETAINER
CROSS REFERENCE TO RELATED APPLICATION
This is a continuation-in-part application of U.S. Serial No. 465,773, filed January 1 , 1990, entitled "Snap and Lock Quick Connector" by Bartholomew which is assigned to the assignee of the present invention.
BACKGROUND AND SUMMARY OF THE INVENTION
The present invention relates to a connector assembly which provides a snap and lock quick connection and which utilizes a one-piece retaining member. The one-piece retaining member helps to prevent the blow out of the O-rings and bushings. In the automotive industry, as well as many other industries, there is a great need for low cost, reliable and easy to assemble components. This need is especially apparent with respect to providing a connection between fluid-carrying conduits, such as fuel or refrigerant lines. In older threaded connectors, substantial assembly time could be accumulated in screwing on a cap to a fitting and tightening the cap down to the proper torque needed to provide a fluid-tight seal. Further, an inventory would have to be maintained to keep track of the number of caps and fittings, and any liners or other components that may be necessary. Also, retightening of the caps may be required to maintain the seal after the automobile or other system has been put in use.
It is also desired in the case where the retaining member is pre-installed in the female to have the retaining member formed such that it is spread open by the male upon insertion. The retaining member accommodates tolerances of the male and permits movement of the male without seriously affecting the abutting function, because of the separated spring portion of the retaining member.
It is also desirable to have a one-piece retaining member which has a means for receiving and retaining a bushing between a male member and the interior of a female member, since a bushing not retained between a male member and female member tends to be expelled by the action of confined pressure.
Accordingly, it is an object of the present invention to provide an improved connector assembly which utilizes a one-piece retaining member for providing a quick connection between fluid conveying conduits.
Another object of the present invention is to provide a preassembled connector housing and one-piece retaining member so that a connection to a tubular fluid conveying conduit may be made in one step without resorting to any tools. Another object of the present invention is to provide a pre-assembled connector housing and one-piece retaining member assembly so that a snapping connection may be made to a tubular fluid conveying conduit.
It is another object of the present invention to provide a pre-assembled connector conduit unit which requires only a one-step snapping connection to be joined to a connector housing.
It is also an object of the present invention to provide an improved one-piece retaining member.
It is also an object of the present invention to provide an improved one-piece retaining member which operates to both secure the conduit in the axial bore of the housing and position the sealing means within the axial bore of the housing.
It is also a more specific object of the present invention to provide a connector assembly which uses a shoulder portion to secure the retaining member inside the housing. It is a more specific object of the present invention to provide a one-piece retaining member which helps to prevent the high pressure blowout of the O-rings and bushings and which helps to form a fluid tight seal.
To achieve the foregoing objects, the present invention provides a snap and lock connector assembly which generally comprises a tubular conduit, a housing, and a one- piece retaining member with two pairs of arms having shoulder-like portions. The tubular conduit is adapted to convey fluid. The housing is formed with an axial bore for receiving the conduit at a first end and for providing a fluid path at a second end. The retaining member is disposed within the axial bore of the housing for providing a fluid tight seal between the confronting tubular conduit portions. In addition, the retaining member is adapted to be in contact with the housing to provide a locking mechanism. The housing also includes radially inward turned flange portions which abut the shoulder-like portions on the arms of the retaining member. Thus, the housing locks in the retaining member until the retaining member is released. The retaining member can be released by depressing the end portions, which causes flexion of the strips at the ring portion, which allows clearance between the inward turned flange portion of the housing and the shoulder-like portions of the arms. in addition, the retainer can also be made and inserted within the housing such that the retaining member can only be released from the housing with the use of a special tool. From the following detailed description taken in conjunction with the accompanying drawings and subjoined claims, other objects and advantages of the present invention will become apparent to those skilled in the art.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to Figure 1 an exploded perspective view of the connector assembly, and Figure 2 a perspective view of the retaining member, of the present invention, is shown. The connector assembly 20 is generally comprised of a female housing 26 and a one- piece retaining member 60. The housing 26 includes an axial bore 30 passing through the housing 26. The connector assembly 20 also includes a conduit 22 having an outward extending annular flange 24, positioned at a predetermined distance from the end of the conduit 22. The housing 26 has a radially inward turned flange 44 which coacts with the retaining member 60 and the annular flange 24 to retain the conduit 22 and the retaining member 60 within the female housing 26.
The sealing and bushing means 38 generally includes a pair of elastomeric O-rings 50 and 52 separated by a washer 54. The O-rings 50 and 52 and washer 54 are retained by a bushing 56. The O-rings 50 and 52 seal the tip of the conduit 22 within the housing 26.
The one piece retaining member 60 includes a ring portion 74 and two pairs of extending arms. The first pair of arms includes 76 and 78. The second pair of arms includes 64 and 66. The ring portion 74 is substantially flat and planar and one side 82 of the ring portion 74 abuts the bushing 56 to maintain the bushing 56 in position. The first pair of arms 76 and 78 extend substantially perpendicular from the other side of the ring portion 74. Although the one-piece retaining member 60 is a one piece molded element, joints 32 exist where the arms 76 and 78 extend from the ring portion 74, and the joints 32 help to allow for flexion as pressure is applied to the depressible end portions 92. The first pair of arms 76 and 78 have substantially identical configurations. Each arm is formed from a pair of extending strips 84 and 86. The strips 84 and 86 are connected by a leg portion 88 having an outwardly extending flange 90. The combination of the leg portion 88 and the flange 90 forms the end portion 92. The end portion 92 and a shoulder-like portion 98 provide an overall T' shape. The end portion 92 which connects the strips 84 and 86 acts as the cross member of the "T". In addition, the outwardly angularly extending shoulder-like portion 98 acts as the body portion of the ".
The shoulder-like portion 98 has an overall shape that serves as a means for abutting the flange 24 to help retain the conduit 22 within the housing 26. In addition, shoulder-like portion 98 helps to maintain the retaining member 60 within the housing. The leading edge 106 of the shoulder portion 98 abuts the flange 24 of the conduit 22 once the conduit 22 is inserted into the housing 26. The shoulder-like portion 98 also has an opposing surface 100 which comes into relatively flat contact with the radially inward turned flange 44 of the housing 26, when the retaining member 60 is inserted into the housing 26.
The second pair of arms 64 and 66 also extend substantially perpendicular from the ring portion 74 on the same side as the first pair of arms 76 and 78. The second pair of arms 64 and 66 are located alternately between the first pair of arms 76 and 78. The arms 64 and 66 have substantially identical configurations and have a substantially planar shape. The body portion 80 of the arms 76 and 78 is substantially planar. The one-piece retaining member 60 is molded with the second pair of arms 64 and 66 extending from the ring portion 74.
Near the approximate middle portion of the body portion 80 of the arms 76 and 78 is a means 70 for abutting the radially inward turned flange 44 to help maintain the retaining member 60 within the housing 26. The means 70 is shoulder-like. The shoulder¬ like portion 70 has an overall shape that extends from the substantially planar arms 64 and 66. The shoulder-like portion 70 helps to retain the retaining member 60 in a position within the housing 26 which in turn maintains the bushing 56, washer 54 and O-rings 50 and 52 within the housing 26. Referring to Figure 3 a side elevational view of the retaining member 60 inserted within the housing 26 is illustrated. As the insertion of the retaining member 60 occurs, once the second pair of arms 64 and 66 clear the radially inward turned flange 44, the shoulder-like portion 70 of the second pair of arms 64 and 66 contacts the inward turned flange 44 of the housing 26. At this time the retaining member 60 is locked within the housing 26 and helps to prevent the high pressure blowout of the O-rings 50 and 52 and bushing 56. The O-rings 50 and 52 seal the tip of the conduit 22 within the housing 26.
Figure 4, also illustrates the side elevational view of the retaining member 60 inserted within the housing 26. Figure 4 is a cross-section of the retaining member 60 inserted within the housing 26, rotated ninety degrees (90°) from the illustration in Figure
3. In Figure 4 the shoulder-like portions 98 of the first pair of arms 76 and 78 are abutting the inward turned flange 44 of the housing 26. The outwardly extending flange 90 of the end portion 92 may extend outside the housing 26.
A second embodiment of this invention would include a retaining member 60 having arms 76 and 78 wherein the arms 76 and 78 do not contain extending flanges 92 which extend outside of the housing 26.
Figure 5 is an end view, of the retaining member inserted within the housing member. The shoulder-like portions 98 of the first pair of arms 76 and 78 are abutting the annular flange 24 of the conduit 22. The shoulder-like portions 70 of the second pair of arms 64 and 66 do not come into contact with the conduit 22.
Figure 6 is a side elevational view of the retaining member 60 and the housing 26 upon separation. In order to separate the retaining member 60 and the housing member 26, pressure must be applied to the two end portions 92 of the retaining member 60 in order to pinch together the end portions 92. As the end portions 92 are pinched together, the shoulder portions 98 are provided with an adequate clearance of the radially inward turned flange 44. Thus, by simultaneously depressing the end portions 92 and pulling the retaining member 60 away from the housing 26, disconnection will occur.
In the second embodiment of this invention, the arms 76 and 78 do not contain extended flanges 92 which extend outside of the housing 26. Therefore, in order to separate the retaining member 60 and the housing member 26 a special tool must be utilized.
While the above detailed description describes the preferred embodiments of the present invention, it will be understood that the present invention is suspectable to modification, variation and alteration without deviating from the scope and fair meaning of the subjoined claims.
