Definitions
- the present invention relates to a pre-assembled connector for sealingly connecting a fluid transport tube and a nozzle.
- the tube is fitted into a rear cylindrical region (fir end) provided with ribs, of the female part.
- the female part also has two seal surfaces for receiving one or two seals with the end piece.
- the mounting of the tube on the ribbed rear cylindrical region called the fir end is not reliable, since it results only from a press fit.
- the quick couplings for tubes currently used also require sealing twice on the one hand between the tube and the quick connector, and between the quick connector and the end piece, as in the case of the two Patents cited above.
- these quick couplings have a high cost.
- connections are produced by the companies NORMA, RAYMOND, LEGRIS, JOHN GUEST, ITT, etc.
- the object of the invention is to simplify the connection while improving its functionalities and in particular to implement a single element guaranteeing sealing, thereby reducing the risk of leakage.
- the invention thus relates to a preassembled connector for sealingly connecting a fluid transport tube and a nozzle provided with at least one attachment element, characterized in that it comprises:
- an attachment device slid over said tube and having at least one attachment element complementary to an attachment element of the end piece;
- the attachment device may have at least one gripping member exerting a leverage on an attachment element to allow disassembly of the connector from the nozzle.
- the attachment device may have a cylindrical region sliding along the tube.
- At least one attachment element can be constituted by a latching arm.
- the attachment device advantageously has a face forming a rear stop for the sealing element.
- This face is for example planar, but it can be concave, the sealing element then having a convex face complementary to this concave face.
- At least one said locking arm and / or at least one gripping member can be connected to an annular ring.
- the invention also relates to a sealed connection between a transport tube and a nozzle, which is characterized by the implementation of a connector as defined above, assembled with the nozzle by cooperation of the attachment elements of the device. attachment and end piece.
- the sealing element can be immobilized by being caught in abutment between the annular bulge of the tube, and the attachment device.
- FIG. 2a a view in longitudinal section of the attachment device (Fig. 2b) , a view along A of the attachment device, and a sectional view of the sealing element (Fig. 2d)
- - Figure 3 shows a preferred embodiment of a connector according to the invention, shown mounted on a nozzle to form a tight connection.
- FIGS. 4a and 4b show in perspective another variant of connection according to the invention, before and after pre-assembly by abutment.
- the invention uses a quick connector pre-assembled on a rigid or semi-rigid tube 4 (that is to say sufficiently rigid to ensure a seal), for example made of metal or plastic, which is put in shape at its end before 42 to form an annular bead 41.
- This shaping can be carried out cold, or hot.
- a sealing element 5 made of elastomer, for example rubber, threaded onto the tube 4 (or overmolded thereon) makes it possible to seal the tube 4 and the end piece 3 by compression, thanks to a attachment device 6, for example made of metal or of thermoplastic material which is threaded onto the tube 4 and which is connected to the end piece 3 which may be of a conventional type, for example a end piece commonly used by automobile manufacturers in the cooling circuits.
- the attachment device 6 can be threaded, in particular by force, or molded onto the tube 4.
- the connector has a number of components each corresponding to a function, namely: a tube 4 for the transfer of fluid, an element 5 in elastomer for sealing, and a device 6 for attachment, for example by snap-fastening.
- the connector being pre-assembled, the assembly is carried out in a single operation, for example by simple snap-fastening.
- the pre-assembled connector comprises an elastomeric sealing element 5, of generally cylindrical shape, the diameter of the internal contour 56 of which is substantially equal to or slightly less than the diameter of the external contour 43 of the tube 4, to allow it to slide along the tube 4.
- the element 5 has on its external cylindrical face 57 and / or on its internal cylindrical contour 56 one or more annular beads 51 and / or 52.
- the tube 4 can be formed to allow 90 ° clearance or other angle.
- the element 5 can be molded around the tube 4.
- the annular bead 41 at the front end of the tube 4 serves as a front stop for the front face 54 of the sealing element 5.
- the attachment device 6 has a cylindrical region 61, the internal contour 69 of which has a diameter suitable for sliding along the external contour 43 of the tube 4.
- the attachment means 6 are for example constituted by latching arms 64 for example two arms located 180 ° from each other (as in Figure 2c).
- Each arm 64 has a ramp region 66 for a pawl 63, which snaps into a groove 34 in a cylindrical region 32 of the end piece 3.
- These arms 64 are for example articulated from an annular ring 62
- a front face 65 of the crown 62 and / or of the region 61 serves as a rear stop for the rear face 55 of the sealing element 5.
- the ramp region 66 cooperates with a corresponding ramp region 33 of the end piece 3 to facilitate the approach of the connector 2 before snap-fastening, which takes place in the position shown in the figure. the.
- the internal face 67 of the arms 64 adjoins the ramp regions 33.
- the rear 55 and front faces 54 of the element 5 are taken into abutment between the face 65 and the bead 41.
- the sealing element 5 then provides the two desired sealing functions, by its internal contour 56 between the tube 4 and the fitting 2 and by its external contour 57, between the fitting 2 and the end piece 3 provided with a base 31.
- a gripping lug 68 is associated with each arm 64 to allow it to be released from the groove 34 ′ by leverage, by slightly deforming the annular crown 62.
- the lugs 68 extend towards the outside of the connector to facilitate handling.
- the annular ring 62 'and therefore its front face 65' is not planar, as in the previous embodiments, but it is concave and its front face 65 'cooperates with a complementary face convex of complementary profile 55 ′ of the sealing element 5.
- This rounded shape allows, by compression of the lugs 68 ′, easy disassembly of the connector 2 relative to the end piece 3.
- the lugs 68 ' are arranged in the extension of the arms 64 and they have an end 68 "folded for example at 90 °, in the direction of the region 61.
- the annular end 41 carries a flat 45 of angular coding. This can also be the case of the seal 5, with an end flat 58, facing the flat 45.
- the flat 45 makes it possible to guarantee the orientation of the tube (in a rotation about its axis), unlike a fir end which can rotate. This indexing can be independent of the orientation of the intermediate components.
- the attachment piece 6 may have a cylindrical crown 71 adjoining the front face 65 and which is extended forwards by two tabs 72 whose internal contour 75 is suitable for fitting in the perimeter of the joint 5 downstream of its rear face 55.
- the front face 73 of the ring 71 is in abutment on the rear face 55 of the seal 5.
- the seal 5 is in abutment by its front face 53 on the annular end 41 and the fitting of the internal contour 75 of the tabs 72 around the joint makes it possible to avoid rotation of the part 6 around the tube 4.
- An angular indexing of the components of the fitting has thus been produced relative to the flat 45, which is required in certain applications where the part 6 must be positioned at a precise angular position relative to the flat 45.
- this angular orientation can be obtained by force fitting the part 6 onto the tube 4, with possible use of the indexing tabs 72.
- the angular indexing by the flat 45 makes it possible to identify angularly a clearance of the tube (at 90 ° or at another angle), for the mounting of the base. There is no need to modify the elements that make up the fitting for this. In other words, there is only one type of connection which allows all the angular clearances, contrary to Art. Previous, where it is necessary to adapt the pieces of fittings.
- the invention makes it possible to make connections for fluid transport tubes (water, antifreeze, oil, fuel, air, refrigerant of air conditioning circuit) more particularly in the automotive field.
- fluid transport tubes water, antifreeze, oil, fuel, air, refrigerant of air conditioning circuit
- Another advantage of the invention is that only the tube 4 and the seal 5 must resist the fluid.
- the invention can be applied in particular to the degassing circuit of an automotive cooling circuit.
