Definitions
- 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.
- fluid-carrying conduits such as fuel or refrigerant lines.
- 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.
- 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.
- retightening of the caps may be required to maintain the seal after the automobile or other system has been put in use.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Figure 1 is an exploded perspective view partially in section of the connector assembly.
- Figure 3 is a side elevation view of the retaining member inserted into the housing member.
- 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.
- 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
- 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.
