Definitions

  • This invention relates generally to a conduit coupling through which fluid flows. More particularly, the present invention relates to a quick connector which retains a male conduit within a female receptacle, and a connection of this type which includes a ring for confirming proper connection.
  • connection between fluid conveying conduits, such as fuel, brake, or refrigerant lines.
  • fluid conveying conduits such as fuel, brake, or refrigerant lines.
  • a connection is comprised of a male conduit being retained within a female receptacle through use of threaded fittings, flare fittings, or through bolted-on flanges.
  • a preferred embodiment of the coupler includes an array of three, or with the indicator, four quick connector engagement components fitted to the end of a male conduit to form a quick connector-male conduit assembly in addition to the parts required for sealing.
  • the array includes an intermediate plate, a retainer, a backing plate, and, as a forth component, a seating indicator.
  • the intermediate plate includes a pair of alignment nibs that align the plate with the adjacent retainer, which itself includes a pair of release and alignment tabs for alignment with the backing plate for use when a metal tube or a plastic tube and tube liner are used.
  • the backing plate also includes a tab which is used for aligning the backing plate with the seating indicator and the retainer.
  • the array of these engagement components is substantially self-centering on the male conduit. Because of the series of alignment members, the engagement components also resist rotation with respect to each other.
  • the retainer includes a ring which fits about a portion of the male conduit and a pair of outer arms on which the release (and alignment to the intermediate plate and the seating indicator) tabs are formed.
  • the ring and the outer arms lie substantially within a common plane.
  • a locking lug is formed along the outer periphery of each of the outer arms for releasable engagement with a locking recessed bore formed along the inner circumference of the axial bore of the female receptacle.
  • the outer arms are coaxial with the ring.
  • the ring and the outer arms are attached to each other at a common area which allows the outer arms to be moved toward one another such as by squeezing, independent of the inner arms.
  • a series of bushings and an O-ring are provided adjacent the array of engagement components to provide for proper seal of the male conduit within the female receptacle, as well as providing for proper fit of these components with respect to each other, such that a bearing on the male portion to the female portion, on each side (inner and outer) of the sealing member is provided.
  • Insertion of the quick connector-male conduit assembly is effected by the installer generally positioning the free end of the male conduit into the female receptacle and (if a seating indicator is used) pushing against a pop-off ring until the ring franges from the body of the seating indicator.
  • the franging action indicates that the quick connector-male conduit assembly is properly seated within the female receptacle.
  • the outer arms of the retainer and their associated locking lugs are squeezed toward the inner arms as the retainer is forced past a concave outer surface formed on the female receptacle.
  • Removal of the assembly from the female receptacle is easily accomplished by the remover squeezing the release and alignment tabs toward one another either by use of a hand or a tool so as to force the outer arms toward the inner arms, thus allowing the locking lugs to clear the radial retainer-locking wall forming the locking recessed bore in the bore of the female receptacle. Once cleared, the remover withdraws the quick connector-male conduit assembly from the female receptacle.
  • the quick connector male is an assembly that is placed directly on the conduit that carries the fluid.
  • the present invention overcomes some of the difficulties associated with assembly and disassembly of known connectors.
  • the retainer does not require assembly to a centering component other than the conduit.
  • the springing interlocking part is like a snap-ring and is in the plane of the locking to the female portions, thus eliminating known springs that undesirably occupy some length parallel to the conduit and are at right angles to the plane of the radial retainer- locking wall of the locking recessed bore and the locking portions carried on the conduit by the springing component. Accordingly, it is an object of the present invention to provide a hand-releasable quick connector that incorporates a relatively thin retainer.
  • a further object of the present invention is to provide a quick connector which can be a part of the conduit between connections.
  • Still another object of the present invention is to provide a quick connector which has a pop-off ring to show when a connection is properly made.
  • Figure 1 shows an exploded view of the quick connector according to a preferred embodiment of the present invention
  • Figure 2 is a sectional view of the quick connector- male conduit elements of Figure 1 assembled and spaced apart from a female receptacle, also shown in section;
  • Figure 3 is a sectional view of a quick connector-male conduit assembly like Figures 1 and 2 locked in position within an alternate embodiment of a female receptacle;
  • Figure 4 is a perspective view of one side of the quick connector intermediate plate according to a preferred embodiment of the present invention
  • Figure 5 is an end view of the quick connector intermediate plate shown in Figure 4;
  • Figure 6 is a perspective view of side opposite that side of the quick connector intermediate plate shown in Figure 4;
  • Figure 7 is a perspective view of the retainer of the assembly according to a preferred embodiment of the present invention.
  • Figure 8 is an end view of the retainer of Figure 7;
  • Figure 9 is a sectional view of the retainer according to a preferred embodiment taken along lines 9-9 of Figure 8;

  • Figure 25 is a perspective view of an alternate embodiment of the retainer fitted to the intermediate plate according to a preferred embodiment of the present invention.
  • the present invention is directed to a quick connector-male conduit assembly incorporating a hand- releasable, self-centering ring-like retainer having a seating indicator assembled therewith.
  • the seating indicator includes a pop-off ring to assist in the installation of the quick connector-male conduit assembly into a female receptacle and to positively indicate to the installer that a male conduit has been locked to a female receptacle.
  • the present invention finds utility in, for example, coupling the tubing disposed between the elements of fuel, water, or oil systems. It may be used with plastic or metal conduits, as shown in the inventor's pending United States patent application Serial No.
  • the connector of the present invention also finds application in external oil lines and hoses as well as in hydraulic brake systems.
  • the present connector may also be used in vehicle fuel systems, between, for example, the fuel tank and the fuel pump and the carburetor or fuel injection system. While having particular usefulness in motor vehicles, the connector of the present invention may also find application in virtually any situation in which male and female fluid- carrying lines must be connected. Referring to Figure 1, an exploded view of a quick connector-male conduit assembly, collectively referred to as 10, and an exemplary female receptacle 11 is illustrated.
  • the female receptacle 11 as illustrated is of the deep drawn type and may be made of a drawn metal or other material.
  • the assembly 10 includes a male conduit 12 (shown broken) .
  • the male conduit 12 is an elongated cylindrically-shaped part having a distal portion or flanged end 13 and a raised collar 14 formed at a predetermined longitudinal distance from the flanged end 13.
  • the raised collar 14 includes a radial wall 15.
  • the assembly 10 acts as a fluid conduit for a fuel, braking or refrigeration system within an automotive vehicle or the like. Therefore, the male conduit 12 must be securely affixed within the female receptacle 11.
  • the assembly 10 also includes a seating indicator 16, a backing plate 18, a hand-releasable, self-centering retainer 20, an intermediate plate 22, a pair of bushings 24 and 26, and an O-ring 28.
  • a seating indicator 16 a backing plate 18, a hand-releasable, self-centering retainer 20, an intermediate plate 22, a pair of bushings 24 and 26, and an O-ring 28.
  • the seating indicator 16, the backing plate 18, the retainer 20, and the intermediate plate 22 collectively form an array of engagement components 29.
  • the bushings 24 and 26 are annular shaped and are preferably defined by quadrilateral walls having rectangular cross sectional shapes. However, as is known to one skilled in the art, such bushings may be U-shaped.
  • the bushings 24 and 26 are useful in "piloting" the assembly 10 into the female receptacle 11.
  • the bushings 24 and 26 are made from a plastic material or a metallic material having sufficient hoop strength to withstand the radially outward-directed forces acting thereupon, or they can be slip-fitted along the conduit from plastic or metal.
  • the O-ring 28 is preferably formed from an elastomeric material such as rubber.
  • the bushing 26 and the O-ring 28 are both sealing and supporting members, and their configuration and even their numbers could be altered as necessary to provide for proper fluid-tight assembly of the male and female components.
  • the engagement components of the array 29, the bushings 24 and 26, and the O-ring 28 are captured between the flanged end 13 and the radial wall 15 of the raised collar 14.
  • the plate 22 acts to receive these separation forces on the male conduit 12 from the bushing 24 and transfer the forces to the female receptacle 11 by interlocking with a radial retainer-locking wall forming one wall of a recessed bore formed in the female receptacle 11, as will be described below.
  • the wall 15 keeps the engagement component array 29 from translating away from the connection.
  • Figure 2 is a modified view of the exploded view shown in Figure 1 showing the components of the quick connector- male conduit assembly 10 assembled on the end of the male conduit 12.
  • the general configuration of the male conduit 12 and its overall design are some of the subjects of the inventor's pending United States patent application, Serial No. 08/503,454, titled MEANS OF COUPLING NON-THREADED CONNECTIONS.
  • part of the end of the female receptacle 11 is fitted within the end of a hose or line 30 which is preferably made from a semi-flexible and expandable elastomeric material such as rubber, however, expandable polymeric and metallic materials can also be used.
  • FIG 2 also illustrates the construction of the female receptacle 11 which is an exemplary but not an exclusive receptacle for use with the quick connector-male conduit assembly 10 of the present invention.
  • the female receptacle includes a throughbore 31 that includes lead-in chamfer 32 formed at the open end of the throughbore 31 of the female receptacle 11.
  • the chamfer 32 aids in the installation of the retainer 20.
  • the retainer 20 is a quick connect fastener that includes outer flexible arms (discussed below with respect to Figures 7 through 12) that are compressibly squeezed inward toward the longitudinal axis of the male conduit 12 by insertion into the lead-in chamfer 32 of the female receptacle 11.
  • the throughbore 31 of the female receptacle 11 also includes a locking recessed bore 33 adjacent the lead-in chamfer 32.
  • the retainer 20 is releasably locked within the recessed bore 33.
  • the semi-flexible hose or tube 30 is attached to the female receptacle 11.
  • the receptacle 34 includes a throughbore 36 having a lead-in chamfer 37, a recessed bore 38, a radial retainer-locking wall 39, an inner conical surface 44, and an inner tubular bore 46.
  • the lead-in chamfer 37 compressibly squeezes the compressible elements of the retainer 20 to thereby allow it to pass into the recessed bore 38 and to lock against the radial retainer- locking wall 39.
  • the inner conical surface 44 pilots the bushing 26 (together with the O-ring 28 and the bushing 24) into the inner tubular bore 46.
  • the seating indicator 16 includes a pop-off ring 48. According to the illustration of Figure 3, a portion of the seating indicator 16 has been inserted into the female receptacle 34 by the operator pushing against the conduit 12. According to the illustrated view, the assembly 10 is locked into place, but the pop-off ring 48 has not yet been broken away. Pressing on the conduit 12 causes further pressure against the pop-off ring 48 applied by the female receptacle 34 end, than that applied to put the assembly 10 in the illustrated position, will cause it to break away from the rest of the seating indicator 16, thus indicating to the installer that the assembly 10 has been locked into place in the female receptacle 34 (or any other embodiment of the female conduit illustrated herein) .
