Definitions
- the present invention relates to a quick connector comprising a male part and a female part which are coupled by simple introduction of one into the other and, more particularly, a quick connector and which has means allowing rapid verification of the quality of the coupling performed.
- the fork must be stiff enough so that its branches cannot be easily spaced from one another by a simple manipulation of rotation around the axis of the coupler, making the wall of the female element play of this coupler a role of cam spreading the branches.
- the device offers significant resistance to the introduction of the male element of the coupler into the female element which can deceive the installer believing that he has reached a correct connection position.
- the object of the present invention is to propose a quick connector with a witness to the quality of the connection which is simple and inexpensive to manufacture and the presence of which is not detrimental for a good connection to be made.
- the subject of the invention is therefore a quick connector comprising an indicator device with a display part projecting outside the connector and a fixing part locked by snapping onto the female part of the connector, this part fixing comprising at least one control element for its unlocking cooperating with an actuating surface carried by the male part of the connector when the latter is correctly placed in the female part which comprises, in a manner known in itself- same, a stage bore whose section of larger diameter can accommodate with radial clearance an external flange of the male part of the connector beyond a latch, the wall of the female part of the connector having at the level of the section more large diameter of the bore, an orifice for installing the fixing part of the indicating device, the edge of the bolt adjacent to it being separated from the latter by a e distance at least equal to the thickness of the flange measured axially while the fixing part comprises a flexible latching tongue in the axial direction of the connector, the end of which projects into the section of the bore on a height greater than the radial clearance when it is introduced into the ori
- the coupler thus defined is very little modified compared to a normal coupler. Indeed, it only has one orifice for the installation of the indicating device and the attachment means of this device offers only a very low resistance to the penetration of the male part of the coupler into the female part.
- the orifice is of non-circular section and the fixing part of the display device includes a foot for its embedding in this orifice of corresponding section.
- the catching tongue When the catching tongue is in use, the extraction movement is not possible even if the tongue is very flexible, which is sought to oppose a minimum force to the coupling of the male and female parts of the connector , this tongue also being very tensile strength when opposed to the extraction of the indicator device.
- the foot is constituted by two legs framing the flexible tongue.
- this connector is such that the fixing part of the indicating device comprises on either side of the tongue curvilinear branches forming a stirrup for supporting the device on the external surface of the female element.
- this stirrup can constitute a clip which constitutes an additional means of holding the indicating device on the connector even when the connection is perfectly made, the effort developed by these two elastic branches forming a clip at the outside of the connector being very weak. In this way, a verifier could ensure that the connection is made correctly by removing the indicating device and, in order not to lose it, replace it, either in the same orientation or in a different orientation to show that the verification has been carried out.
- this stirrup may include curvilinear branches whose radius is less than that outside of the body of the connector.
- FIG. 1 is an axial section view of a connector according to the invention in a state where the connection is not perfectly made
- FIG. 2 is a sectional view identical to that of FIG. 1 illustrating a correctly made connection
- FIG. 3 is an external view along F of FIG. 1 of the indicator device alone
- a connector 1 according to the invention comprises a female part 1 divided into several sections.
- a first section 2 has an internal channel 3 and external means 4, called fir tree tooth, to be introduced inside a tube not shown.
- the second section 5 of this part 1 has a bore 6 of determined diameter to accommodate the nose of a tip 7 forming the male part of the connector.
- the third section 8 of this male part has a bore 9 of larger diameter than the bore 6 to accommodate two O-rings 10 and a blocking insert these 11.
- the internal diameter of one insert is equal to the diameter of the bore 6.
- the female part 1 has a third section 12 whose internal diameter 13 is even larger than that of the preceding bores in order to allow the free passage with a radial clearance "e" of a flange 14 carried by the end piece 7.
- the last section 12 of the female part 1 comprises a latch 15 to prevent the extraction of the end piece 7 when it is correctly inserted into the female part 1.
- This lock 15 is constituted by a ring which can slide radially in the female part 1 in an open housing, produced in the latter and which comprises one or two elastic tabs outer 16 which tend to offset the inner bore of the ring 15 relative to the bore 13.
- a portion of this inner bore of the ring 15 is in the form of a conical surface 17 so that the passage of the flange 1 4, the ring 15 is lowered to 1 "against the effect of the elastic blades 16 until the flange 14 is housed in the bore 13 beyond this ring 15.
- the tongues 16 are then decompressed and the ring is found in a free offset position relative to the bore 13 and one of these flanks makes contact with the rear flank of the flange 14 and constitutes a stop sOpposant to the ex ⁇ traction of the end piece 7.
- This state of the connector is shown in FIG. 2 and illustrates a connection that is correctly made.
- the wall of the female part 1 has an orifice 18, for example of rectangular section, opening out at the bore 13.
- This orifice therefore has an edge 19 which is located as close as possible to the latch 15.
- the distance "a” separating this edge 19 from the side of the ring 15 which cooperates with the collar 14 to retain the end piece 7 is at least equal to the thickness "b" measured axially, of this collar 14.
- the orifice 18 is intended to receive an indicator device 20 which comprises a gripping and display part produced in the figures in the form of a disc 21 and a fixing part 22 intended to cooperate with the female part 1 of the connector.
- This fixing part 22 comprises two rigid tongues 23, 24 whose width "c" is equal to the dimension of the orifice 18 measured axially, these tongues 23 and 24 being separated from each other by a distance such that they bear on the edges of the orifice 18 not shown in FIGS. 1 and 2. These tongues form a foot for embedding the device 20 in the orifice 18.
- This mounting base may include an upper base forming a stop at its penetration into the orifice 18.
- this upper base is in fact formed by two curvilinear arms 25 and 26 which partially embrace the outer contour of the female part 1 of the connector.
- the part 22 for fixing the indicator device 20 comprises a tongue 27 extending in a plane substantially radial to the connector when the device 20 is put in place, this tongue being elastically flexible under the effect of an axially directed effort.
- the free end of this lan ⁇ guette is shaped into a hooking tooth 28 which, when the base 25, 26 of the device 20 bears on the outer surface of the part 1, slides elastically under the edge 19 of the orifice 18 and forms a retaining member of the device 20 which can no longer be extracted from the orifice in which it is implanted.
- the projection formed by this tooth 28-1 'inland r of the bore 13 is a dimension "d" in a radial EXCEED “e” between the collar 14 and the bore 13 so that when puts the tip 7 inside the female part 1, the flange 14 abuts on the tooth 28 before the latch 15 engages elastically behind it. When this insertion is continued, the tongue 27 is bent by opposing the penetration of the nozzle 7 a minimum resistant force.
- the arms 25, 26 play the role of a spring which is crushed between the connector and held by the tongue 27 hooked under the edge 19.
- This tongue is released, the device is ejected from the orifice 18 by the spring effect of the arms 25 and 26 and can no longer be held there.
- the tabs 25 and 26 can form an elastic clip retaining the device 20 on the body of the connector even when the latter is no longer attached to this body by the tongue 27 To do this, it is enough that these legs embrace more than half an outer circumference of the female part 2. This arrangement makes it possible to rotate the connector relative to the end piece, the device 20 then being able to be located with the disc 21 in the lower part without it detaching itself unexpectedly from the connector when the connection has been made.
