The present invention relates to a fluid connector equipped with a pressure sensor, the fluid connector comprising: a body having two fluid connector ends; an assembly interface disposed on and within the body, the assembly interface including an orifice that positions the internal duct to communicate with the outside of the body, a first receiving area extending around the orifice, a second receiving area extending around the first receiving area, and a mounting area; a pressure sensor that establishes contact with the first receiving area via a first gasket; and a cover disposed on the pressure sensor that establishes contact with the second receiving area via a second gasket to isolate the pressure sensor from the external environment.

Description

[Technical Field]

[0001] The present invention relates to the field of fittings and connectors for enabling fluid communication between pipes or ducts, particularly for motor vehicles, and in particular to fluid connectors equipped with sensors for measuring a property, such as the pressure, of a fluid circulating in an internal duct of said connector. [Background technology]

[0002] Automotive fluid connectors are widely used to connect flexible hoses to rigid tubing on various fluid lines in a vehicle, particularly on liquid or vapor fluid lines that make up the fuel system.

[0003] Advances in diagnostics and functional checks for modern vehicle engines have increased the need for monitoring fuel system operating conditions, particularly fluid pressure. Therefore, it is desirable to have a fluid connector equipped with a sensitive and robust pressure sensor compatible with this environment.

[0004] Patent document 1 is known and proposes a fluid quick connector that integrates a chamber into the outer cylindrical wall to accommodate a pressure sensor. The sensor communicates with an internal duct of the connector. The chamber is closed with a cover. The drawback of this approach is that forming the chamber requires an elevated partition above the outer wall of the connector, significantly increasing the volume of the fluid connector. In addition, since the electrical connector is overmolded with the duct, this approach does not provide any modularity to the fluid connector.

[0005] Patent Document 2 also discloses a quick connector for fluids equipped with a sensor, such as a pressure sensor. The connector includes a body through which the fluid circulates, a support base disposed on the body, and a mounting element connected to the support base. The compactness and robustness of this type of connector still need to be improved. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE INVENTION

[0011] In the illustrative part, the same references in the figures may be used for elements of the same type.

[0012] The present invention relates to a fluid connector 1 equipped with a pressure sensor 10, an example of which is shown in an exploded view in Figure 1a and in an assembled configuration in Figure 1b.

[0013] The fluid connector 1 comprises a body 20 that is generally cylindrical and has two fluid connector ends 21, 22. In the example shown, one of the fluid connector ends is a quick connector end 21, as known in the art. In general, the invention applies to any type of end.

[0014] The generally cylindrical body 20 defines an internal duct 23 through which a fluid is intended to circulate.

[0015] The fluid connector 1 also includes an assembly interface 200 disposed on and within the body 20. More specifically, the assembly interface 200 forms part of a wall of the body 20 and accommodates fittings made on and within the wall.

[0016] The assembly interface 200 includes an orifice 24 that passes through the wall of the body 20 and positions an internal duct 23 that communicates with the outside of the body 20. It also includes a first receiving area 25 that extends around the orifice 24 and a second receiving area 26 that extends around the first receiving area 25. These receiving areas 25, 26 define flat or sloped annular surfaces, preferably concentric surfaces, as will become apparent during the description of various embodiments. They are so named because they provide locations for receiving a first gasket 35 and a second gasket 36, respectively. Additionally, the first receiving area 25 provides a point of contact with another element of the connector 1 (the pressure sensor 10) via the first gasket 35, which provides a sealed connection between the element and the body 20, and the second receiving area 26 provides a point of contact with another element of the connector 1 (the cover 40) via the second gasket 36, which provides a sealed connection between the element and the body 20.

[0017] Finally, the assembly interface 200 includes attachment areas 27. As shown in Figure 1c, these attachment areas 27 are located around the periphery of the body 20, on either side of the second receiving area 26.

[0018] The fluid connector 1 also comprises the above-mentioned pressure sensor 10. This sensor 10 comprises a connecting cylinder 11 that allows the fluid to be conveyed to the pressure measuring cell. The connecting cylinder 11 is arranged in or opposite the orifice 24. Advantageously, said connecting cylinder forms a ridge that extends into the orifice 24 and is flush with the internal duct 23 or projects substantially into the internal duct 23. Alternatively, the connecting cylinder 11 may consist only of an opening that places the fluid in communication with the pressure measuring cell.

[0019] The pressure sensor 10 also includes a printed circuit, for example of the printed circuit board (PCB) type, which supports the electronics and the electrical connector terminals 12 of the sensor 10 .

[0020] The pressure sensor 10 establishes contact with the first receiving area 25 via the first gasket 35, providing a seal between the internal duct 23 and the outside of the body 20. The first gasket 35 may have a variety of shapes to fit the first receiving area 25, and preferably it is made of an elastomeric material. Alternatively, the gasket 35 may be made as an adhesive strip, in which case the pressure sensor 10 is integral with the body 20.

[0021] According to a first embodiment shown in Figures 1a-1e, the first receiving area 25 comprises a housing coaxial with the orifice 24, with the connecting cylinder 11 forming a protrusion extending into said housing. A first gasket 35 is disposed within the housing and around the protrusion to provide a radial seal between the internal duct 23 and the outside of the body 20. The seal is provided by radial compression of the gasket 35 relative to the plane and vertical plane of the housing of the first receiving area 25 (i.e. parallel to or tangent to the plane (y, z) in the figures) and the protrusion of the connecting cylinder 11, respectively.

[0022] According to a second embodiment shown in Figures 2a, 2b and 2c, the first receiving area 25 includes a conical extension that is continuous with the orifice 24. The pressure sensor 10 has a shoulder, and a first gasket 35 is disposed within the conical extension and bears against the shoulder to provide a seal between the internal duct 23 and the outside of the body 20. Here, the seal is provided by axial and radial compression of the gasket 35 against the inclined surface of the extension of the first receiving area 25 and against the wedge formed by the shoulder of the sensor 10.

[0023] According to a third embodiment shown in Figures 3a, 3b and 3c, the pressure sensor 10 includes a shoulder against which a first gasket 35 is placed, said gasket being compressed by the pressure sensor 10 to provide an axial seal between the internal duct 23 and the outside of the body 20. The seal is provided by compressing the gasket 35 axially against the flat and horizontal surfaces (parallel to the plane (x, y) in the figures) of the first receiving area 25 of the sensor 10 and the shoulder, respectively.

[0024] Finally, returning to the general description of the present invention, the fluid connector 1 comprises a cover 40 disposed over the pressure sensor 10. The cover 40 contacts the second receiving area 26 through the second gasket 36 and isolates the pressure sensor 10 from the external environment (particularly humidity, dust, etc.). To do this, the second receiving area 26 completely surrounds the space occupied by the sensor 10 on the body 20, and the cover 40 completely surrounds the sensor 10.

[0025] Note that in the case of a relative pressure sensor, a ventilation system 45 is attached to the cover 40 to provide access to the external pressure, as shown in FIG. 4a.

[0026] The cover 40 further comprises two side wings 41 that extend at least partially around the body 20 to cooperate with the mounting area 27 and enable assembly of the cover 40 on the body 20. The configuration of the side wings 41, which allows the cover 40 to overlap the body 20, improves the mechanical stability of the cover 40 on the body 20 and thus the robustness of the connector 1, and also reduces the volume associated with integrating the pressure sensor 10, providing a functional and compact connector 1. Furthermore, this configuration effectively protects the electronics of the sensor 10 from dust.

[0027] Several methods may be used to attach the cover 40 onto the body 20, for example the two side wings 41 may be clipped, joined or welded to the attachment area 27.

[0028] In the particular case of assembly by clamping, each side wing 41 advantageously includes at least one tooth 41a at its end and each attachment area 27 includes at least one groove to enable one to be clamped onto the other (Figs. 1c, 2c, 3c). More advantageously, the tooth 41a of each side wing 41 has a gradual profile and / or each side wing 41 has a beveled edge at its end (Fig. 1d), allowing gradual elastic deformation during assembly of the cover 40 onto the body 20 until the cover 40 is clamped in place.

[0029] Of course, each side wing 41 can be provided with at least one groove or window 41b at its end (instead of or in addition to teeth 41a), and each attachment region 27 can be provided with at least one tooth 27a to allow one to be clamped to the other, such variations being shown in Figures 4a, 4b, and 4c. As shown in Figure 1d, the main body 20 can advantageously be provided with beads 29 along the edges of the side wings 41 to block access to the attachment regions 27 and prevent disassembly of the connector 1.

[0030] When assembly is achieved by clipping, the second gasket 36 is advantageously an elastomeric material, an O-ring, or a gasket of another shape suitable for the second receiving area 26. In the example shown in Figure 1e, the second gasket 36 is substantially square or rectangular in shape, identical to the contours of the cover 40 (and of the second receiving area 26, which is not visible in the figure).

[0031] In the case of assembly by bonding, the end of each side wing 41 may be bonded to the associated attachment area 27. According to another option, all edges of the cover 40 in contact with the body 20 may be bonded to said body 20 by means of a continuous peripheral adhesive strip, and the second gasket 36 can then comprise or consist of said strip of adhesive material.

[0032] In the case of assembly by welding, the end of each side wing 41 may be welded to the associated attachment area 27. According to another option, all edges of the cover 40 in contact with the body 20 may be welded to said body 20 forming a continuous peripheral weld bead, and the second gasket 36 may then include or consist of this weld bead.

[0033] In the particular case where the body 20 has a region in which the diameter at the level of one of the fluid connector ends is narrower than at the level of the end 22, as shown, for example, in Figures 1a and 1b, the cover 40 may be provided with a transverse wing 44 resting on the narrowed region, which enhances the mechanical stability of the cover 40 on the body 20.

[0034] Finally, the cover 40 of the fluid connector 1 according to the invention comprises an electrical connector end 42 for connecting the pressure sensor 10 to the outside. In particular, metal pins 43 connected to the electrical connector terminals 12 of the sensor 10 lead to and extend into the electrical connector end 42. The connection between the terminals 12 and the pins 43 can be provided by spring contacts or, alternatively, by conductive solder. Spring contacts are particularly advantageous because they allow adjustment of the PCB (of the sensor 10) and the position of the connecting cylinder 11 that needs to enter the orifice 24, and generally they ease the dimensional constraints of the component and provide better resistance to vibrations and shocks.

[0035] The pins 43 may be overmolded or force fitted to the cover 40. The pins allow for connection of the sensor 10 to, for example, an external controller.

[0036] According to a variation that provides flexibility in mounting and modularity to the fluid connector 1, the cover 40 may have a shape that is symmetrical about a longitudinal plane (y, z) that passes through the central axis y of the internal duct 23 and through the center of the orifice 24. The assembly interface 200 is also symmetrically positioned along this same longitudinal plane (y, z). This symmetry allows the assembly formed from the cover 40 and the pressure sensor 10 to be mounted to the body 20 with the electrical connector end 42 located on the side of the first end 21 or on the side of the second end 22 of the fluid connector 1.

[0037] It should be noted that to facilitate assembly of the connector 1, it is also possible to provide an assembly interface 200 including at least one centering pin 28 to aid in positioning the pressure sensor 10 and / or cover 40 onto the body 20 (Figures 1a, 2a, 3a).

[0038] Advantageously, the fluid connector 1 comprises an elastic element 30 to ensure mechanical retention of the sensor 10, i.e., to hold the wedge between the cover 40 and the body 20, to compensate for dimensional variations and mounting clearances during assembly, in particular by clipping. In particular, the printed circuit board of the pressure sensor 10 may have a non-uniform and / or non-reproducible thickness from one sensor to another. It is therefore advantageous to have an elastic element 30 that accommodates these tolerances and ensures that the sensor 10 is pressed simultaneously between the cover 40 and the body 20 without changing the calibration of the sensor 10.

[0039] The resilient element 30 also provides the advantage of acting as a damper to absorb potential vibrations transmitted by either the body 20 or the electrical connector end 42 of the cover 40. Thus, the fluid connector 1 may be compact without requiring reinforcement by additional material, regardless of the frequency of vibrations encountered.

[0040] Such an elastic element 30 may be disposed between the cover 40 and one face of the pressure sensor 10 (where the only contact between the cover 40 and the sensor 10 is established via the elastic element 30), with the other face of the sensor 10 being in contact with the body 20, as illustrated in Figures 1b, 1c, 2b, and 2c. Alternatively, the elastic element may be arranged between one face of the pressure sensor 10 and the body 20 (the only contact between the body 20 and the sensor 10 being established via the elastic element 30), with the other face of the sensor 10 being in contact with the cover 40. In a third embodiment shown in Figures 3a-3c illustrating the configuration of a first gasket 35 providing an axial seal, it is proposed that the first gasket 35 functions as an elastic element due to its arrangement between the bottom face of the sensor 10 and a surface of the body 20 (first receiving area 25) parallel to said bottom face. The elastic element 30 shown in Figures 3a, 3b and 3c is then optional.

[0041] By way of example, the elastic element 30 may be made as a spring or elastomeric material.

[0042] Generally, when formed from an elastomeric material, the elastic element 30, the first gasket 35, and / or the second gasket 36 may be overmolded onto the cover 40 or onto the body 20, or may be attached to the cover 40 or to the body 20.

[0043] Likewise, at least one of these three elements 30, 35, 36, or all three, may have a particular annular shape configured to reduce compressive forces during assembly of the cover 40 on the body 20. For example, the annular shape may have a cross section with a thinner central portion, which limits the resistance of the elastic element 30 and / or the gaskets 35, 36 to crushing.

[0044] The particular structure of the fluid connector 1 according to the invention gives it modularity, robustness and compactness. In particular, the cooperation of the cover 40 and the assembly interface 200 allows for a significant limitation of volume while still effectively maintaining and protecting the pressure sensor 10 from the external environment.

[0045] It is conceivable that the pressure sensor 10 is fixed (for example by bonding) to the cover 40 or to the body 20. It is noted that if it is fixed to the body 20, this provides additional safety against the risk of leakage of fluid entering the internal duct 23 in case of accidental removal of the cover 40. In effect, the pressure sensor 10 integrated with the body 20 functions as a safety plug by cooperating with the first receiving area 25 via the first gasket 35.

[0046] Naturally, the present invention is not limited to the embodiments and examples that have been described, and alternative embodiments may be added without departing from the scope of the invention as defined by the claims.
