Electrical connector for an electrical component of a motor vehicle comprising at least two sealing devices

The present invention relates to the field of electrical components for a motor vehicle, and more particularly to the field of electrical connectors for electrical components of a motor vehicle.

Numerous electrical connectors are known for electrical components of a motor vehicle. Without limitation, these electrical components can be an electric compressor or an electronic computer, or even a power module, for example.

These components can be placed in the engine compartment of a motor vehicle.

These components include a control module supplied from an electrical current source external to the electrical component. This control module is generally placed in an internal chamber of the electrical component.

To electrically supply such a component from an external electrical current source, an electrical connector is commonly used. To ensure

0 the power supply of the control module disposed in the internal chamber of the electrical component, such a connector is disposed in an opening made on an external wall of this component, the external wall being in a part of the motor vehicle which may be exposed to the weather.

Such a connector generally comprises two parts each arranged on one side

5 of the external wall of the electrical component and each facing the same opening in said wall, the two parts being mounted relative to each other to form the connector. Once mounted, such a connector can supply the control module from the external electrical current source.

A first objective is to seal such a connector to avoid the insertion of

0 any foreign bodies in the internal chamber from the opening, the foreign bodies being present in the part of the vehicle in which the electrical component is disposed.

The document FR 2 983 001 A1 proposes a solution consisting in ensuring compression maintenance of two elements forming an electrical connector, the two elements being arranged on either side of a wall. The two elements are held together by means of a clamping screw passing through one of the elements of the connector to be housed in the other element. A peripheral seal is placed between one of the elements and the wall. This has the effect of holding the two parts of the connector together in compression by one of their faces against the wall of the component. However, this solution does not ensure good sealing of the electrical connector.

The present invention aims to overcome at least one of the aforementioned drawbacks and to provide a sealed electrical connector making it possible to maintain the two parts of the electrical connector together.

To this end, the subject of the invention is an electrical connector configured to be mounted in an opening in a wall of an electrical component of a vehicle, the connector comprising a first element and a second element, the first element being configured to be arranged on a first face of the wall opposite the opening, the second element being housed at least partially in the opening, the second element being received in a through barrel formed in the first element, characterized in that the electrical connector comprises a sealing device arranged on an external contour of the second element.

Thanks to these characteristics, it is possible to seal the electrical connector in a zone of contact of the second element with the wall of the electrical component or with the first element. In this way, the level of tightness is raised, avoiding any liquid migration, for example, between the first part and the second part. During a maintenance operation, disassembly of the electrical connector is also facilitated.

According to one embodiment of the invention, the sealing device prevents the flow of a fluid along the outer contour of the second element.

Thanks to this characteristic, it is possible to prevent the flow of a fluid which can flow along a passage between the second element and the wall or along a passage between the second element and the first element.

According to another embodiment of the invention, the sealing device is arranged between the second element and the first element.

According to one embodiment of the invention, the sealing device is configured to be in contact with the wall.

The sealing device is thus capable of implementing a sealing by contacting the wall and / or, for example by contacting an internal face of the barrel passing through the first element.

According to one embodiment of the invention, the second element comprises a first body part and a second body part disposed respectively along an axis of the electrical connector, in particular a longitudinal axis of this connector, the second body part extending transversely relative to the longitudinal axis of the connector beyond the first body part, the second body part housing the first sealing device, advantageously in a peripheral groove formed on the second body part.

According to another embodiment of the invention, the second body part is configured to bear, both against the wall and against part of the first element.

According to yet another embodiment of the invention, the second element comprises a head extending transversely relative to the longitudinal axis of the connector beyond the second body part and configured to come to bear against a second face of the wall of the component opposite to the first face of this wall.

According to a variant of the invention, the sealing device is configured to be disposed between the head of the second element and the second face of the wall.

Advantageously, the head of the second element houses the sealing device.

According to another variant of the invention, the second element is provided with a through housing housing at least partly an electrical conductor.

Advantageously, a binder material is disposed between the electrical conductor and a wall delimiting the through housing.

The term “binding material” means any organic or synthetic material capable of ensuring a mechanical connection between two parts. For example, the binding material can be glue or even resin. This binding material can also provide sealing in a point of contact by which two parts are assembled to one another.

Advantageously, the binder material disposed in the through housing maintains the electrical conductor in the through housing of the second element and prevents the flow of a fluid along the through housing.

According to another variant of the invention, the electrical conductor is provided with at least one L-shaped power pin formed by a first portion connected to a second portion by an elbow, the first portion being housed in the through housing of the second element . In this situation, the second portion and the elbow are outside the through housing, in particular outside the connector according to the invention.

Advantageously, the electrical conductor comprises at least one signal pin. Even more advantageously, at least two signal pins are arranged between two power pins in L. Advantageously, the two signal pins are configured to detect an opening of an electric circuit supplying electrically

0 the two power pins in L.

A power pin is dimensioned to conduct an electric current which supplies the electrical component, while the signal pin is dimensioned to conduct a control signal or a diagnostic signal.

According to one embodiment of the invention, the electrical connector comprises at least 2 a locking device configured to keep the second element in abutment against the wall.

According to another embodiment of the invention, the blocking device is configured to bear against the wall and, simultaneously, against the second element, and in particular against its head.

The locking device comprises a fixing part and an axial holding part. The fixing part is fixed to the wall. Advantageously, the axial holding part is in abutment against the second element, and in particular against its head.

According to another embodiment of the invention, the locking device comprises at least one metal tongue with a spring effect.

According to a particular embodiment of the invention, the blocking device is formed by a binding material arranged between the second element and the wall.

According to another particular embodiment of the invention, a shielding sheath is arranged in the through barrel between the first element and the second element.

The sealing device arranged on an external contour of the second element is called the first sealing device when the electrical connector comprises a second sealing device configured to seal a contact between the first element and the first face of the wall on or against which is arranged the first element. Thus and for the whole of this document, the sealing device disposed on an external contour of the second element can be understood as being the first sealing device, and therefore replaced by the latter, since the connector comprises a second sealing device.

It is understood here that the first sealing device is distinct and separate from the second sealing device. The first sealing device therefore partially surrounds

0 an outer periphery of the second element, coming into contact with the latter.

The invention also relates to an electrical component of a vehicle comprising at least one electrical connector according to the invention.

The invention also relates to an electric compressor of a refrigerant circuit for a motor vehicle, comprising at least one electrical connector according to

5 the invention.

According to one embodiment of the above according to the invention, the method comprises a step of inserting the electrical conductor into the through housing of the second element.

According to one embodiment of the method according to the invention, the method comprises:

- A step of positioning the blocking device on the wall and pressing against the second element;

Figure 1 shows the electrical connector 1 mounted on a portion of a wall 2

0 of an electrical component housing an internal chamber 200 in which a control module of the electrical component can be arranged, a printed circuit board 17 of which is shown. The portion of the wall 2 comprises an opening 5. The portion of the wall 2 is delimited by a first face 21 and a second face 22. The first face 21 corresponds to an external face of the electrical component which can be exposed to a

5 environment including foreign bodies, including water splashes. The second face 22 corresponds to the inner face of the electrical component forming in part the internal chamber 200 housing the control module of the electrical component. This second face 22 thus delimits an internal chamber 200 of the electrical component in which extends for example the printed circuit board 17. It will then be understood that a desired aim is to avoid the insertion of foreign bodies in the internal chamber 200 , passing through the opening 5 formed in the wall 2 of the electrical component.

To achieve this objective, the connector 1 according to the embodiment of Figure 1 comprises a first element 3 disposed opposite the opening 5. The first element 3 comprises a bearing face 31 from which extend an internal part 32 and an external part 33 of the first element 3, the internal part 32 being thus qualified in that it is housed inside the opening 5, for example against a first internal surface 51 of the opening 5 of the wall 2. The opening 5 also includes a second internal surface 52 of a section greater than the first internal surface 51. The first element 3 is thus in abutment against the wall 2 by its support face 31 and the internal part 32 is inserted into the opening 5. The external part 33 of the first element 3 then being from the bearing face 31 towards the outside of the electrical component opposite the internal part 32, the external part 33 of the first element 3 so qualified in this way that it extends outside the opening 5. The external part 33 of the first element 3 comprises a cavity 35 at its center.

A sealing device, hereinafter referred to as second sealing device 6, is disposed in a housing 34 of the bearing face 31 of the first element 1 and makes it possible to seal between the bearing face 31 and the first face 21 of the wall 2. The first element 3 comprises a through barrel 7 which passes through its internal part 32 and its external part 33.

The first element 3 is secured to the wall 2 by any fixing means, such as one or more screws, or even rivets.

The electrical connector 1 comprises a second element 4 inserted in the opening 5 of the wall 2 from the second face 22 of the wall 2. It is therefore understood that the first element 3 is pressed against the first face 21 from the middle surrounding the wall 2, while the second element 4 is inserted into the opening 5 taking from the internal chamber 200 delimited in part by the second face 22 of the wall 2.

The second element 4 comprises an external contour 41 partly of complementary shape with the internal contour of the first element 3 formed by the through barrel 7, so as to accommodate the second element 4 in the first element 3. The second element successively comprises along of a longitudinal axis X of the connector, a first body part 8, a second body part 10 and a head 12. The first body part 8 is disposed partly in the through barrel 7 of the first element 1 and partly in the cavity 35 of the first element 1, a shielding sheath can be interposed between parts. The second body part 10 extends transversely relative to the longitudinal axis X of the connector beyond the first body part 8 to form a peripheral zone 81 opposite the second internal surface 52 of the opening 5 of wall 2.

The external contour 41 of the second element 4 is formed for all the external surfaces of the second element 4, that is to say the surfaces of the second element 4 facing the first element 3 and / or facing the wall 2.

To ensure axial retention of the second element 4 in the first element 3, the head 12 of the second element 4 extends transversely with respect to the longitudinal axis X of the connector towards the outside beyond the second body part 10 to be supported by its face 120 against the second face 22 of the wall 2.

The head 12 of the second element 4 comprises a stud 125 extending in its center along the longitudinal axis X of the connector in a direction opposite to the second face 22 of the wall 2.

A shielding sheath 11 is arranged between the first element 3 and the second element 4 in a space delimited between the first element 3 and the second element 4. The shielding sheath 11 makes it possible to contain and to ground all electromagnetic disturbances which may be emitted from the electrical connector 1. This protection is ensured by earthing this shielding sheath 11 by connection to the wall 2, when this wall is metallic.

In the assembled state, the second element 4 is housed in the first element 3 via the through shaft 7, the first body part 8 of the second element 4 then passes through the internal part 32 of the first element 3 and cuts the face support 31 of the first element 3, to be housed in the cavity 35 of the external part 33 of the first element 3. The first element 3 and the second element 4 are configured to make in the assembled state a contact between the second part body 10 of the second element 4 and the internal part 32 of the first element 3. The first body part 8 is then partly opposite the barrel 7 passing through of the first element 3.

A sealing device, hereinafter called the first sealing device 9, is disposed in a peripheral groove 100 formed on the second body part 10 of the second element 4. The first sealing device 9 is then in abutment. one side against the second internal surface 52 of the opening 5 of the wall 2 to make a sealed contact with the latter, and on the other against the second element 4 to make a sealed contact with the latter. This prevents the entry of foreign bodies into the internal chamber 200 since the space between the first element 3 and the second element 4 is sealed by means of the first sealing device 9.

According to an exemplary embodiment, the first sealing device 9 is an O-ring or even a lip seal. In this embodiment of Figure 1, the sealing device 9 is a lip seal ensuring a seal in a plane transverse to the longitudinal axis X of the connector.

The second element 4 also comprises a through housing 13 which can at least partially house an electrical conductor 14, the electrical conductor 14 comprising at least one L-shaped power pin 141 comprising a first portion 141a and a second portion 141b connected together by a bend 141c. The first portion 141a of the L-shaped power pin 141 is housed in the through-housing 13. The first portion 141a comprises a portion 14d of larger cross section extending in the extension of the first portion 141a along the longitudinal axis X of the connector and comprising at its end a rod 141e housed in the cavity 35 of the first element 3. The rod 141e is then accessible from the first face 21 of the wall 2 and forms a connection element for the electrical connector 1.

In FIG. 1, only one L-shaped power pin 141 is shown. In this embodiment, two L-shaped power pins 141 are used, the rods 141e of each pin form the connection elements by which the control module of the electrical component is electrically supplied. These L 141 power pins are dimensioned to participate in the power circuit which supplies the electrical component, the voltage at the terminals of these two L 141 power pins can be between 400 V and 600 V. The L power pins 141 therefore pass right through the wall 2 and are configured to transport an electric current from an external beam, or external current source, to the electric component towards the internal chamber 200 of this component.

To maintain each L-shaped power pin 141 in the through housing 13, the portion 14ld of larger cross section of each L-shaped power pin 141 includes at its end a retaining lug 14lf extending transversely outside the through housing 13 or which can be housed in an internal face 132 of the through housing 13. A binding material 131 can be inserted into the through housing 13 before the insertion of the electrical conductor 14 and makes it possible to maintain the electrical conductor 14 in the through housing 13 and the seal along the through housing 13. Alternatively, the binder material can be cast in a space which extends between the L-shaped power pin 141 and the internal face 132 of the through housing 13. In both case, the power pins in L 141 and the second element 4 form a one-piece sub-assembly, in that it is preassembled before its insertion in the o opening 5.

A blocking device 16 is used to maintain the second element 4 against the first element 3 by means of the head 12 of the second element 4. This blocking device 16 comprises two metal tongues 161 with spring effect, only one of which is visible in FIG. 1. These metal tabs 161 each comprise a curved portion 161a which makes it possible to ensure the spring function of the metal tabs 161.

The second portion 141b of the L-shaped power pin 141 is arranged in a direction concurrent with a plane P containing the printed circuit board 17 in order to be secured to the latter. It will be noted that the axial retention of the head 12 of the second element 4 against the face 22 of the wall 2 makes it possible to ensure stable retention of the second portions 141b of each pin when they are secured to the printed circuit board 17. From in this way, the flexion that can be exerted on these second portions 141b is greatly limited at a point where it is secured to the printed circuit board 17. The stud 125 of the head 12 also participates in the stable maintenance of the second portions 141b of each pin when they are secured to the printed circuit board 17.

FIG. 2a represents another embodiment of the electrical connector 1 similar to that of FIG. 1. In this embodiment, the locking device 16 is formed by a binder material 162 disposed between the face 120 of the head 12 and the second face 22 of the wall 2. The second body part 10 of the second element 4 comprises a groove 122 in which the first sealing device 9 is housed. In this embodiment, the first sealing device 9 is for example an O-ring. The first body part 8 of the second element 4 comprises a clearance 82 allowing an extension part 130 extending towards the first body part 8, from the second body part 10, to be pressed against the internal part 32 of the first element

3. Alternatively in all the embodiments described, the first sealing device 9 can be arranged between the first element 3 and the second element 4.

Figure 2b shows another embodiment of the electrical connector 1 similar to that of Figure 2a. In this embodiment, the first sealing device 9 is a seal, for example an O-ring disposed between the face 120 of the head 12 of the second element 4 and the second face 22 of the wall 2. In this configuration, the seal undergoes a axial force ensuring that it remains in contact against the second face 22 of the wall 2 and the face 120 of the head 12 of the second element 4. The force generated on the joint can be exerted by the locking device described in the different modes of production. In this embodiment, the sealing of the first sealing device 9 is carried out in a

0 plane parallel to the longitudinal axis X of the connector.

According to the embodiment of FIG. 1 or 2a, the first sealing device 9 is in abutment against the second internal surface 52 of the wall 2 delimiting the opening 5, to make a sealed contact between the second element 4 and the wall 2.

According to the embodiment of Figure 2b, the first sealing device 9 is

5 rests against the second face 22 of the wall 2 to make a sealed contact between the second element 4 and the wall 2.

FIGS. 3a to 3h represent the steps for mounting the electrical connector 1 on the wall 2. In FIG. 3a, the first element 3 of the connector 1 is shown in a position before it is mounted on the first face 21 of the wall 2. The first element 3

0 comprising the first sealing device is positioned opposite an opening 5 of the wall 2. In FIG. 3b, the bearing face 31 of the first element 3 is then placed in abutment against the first face 21 of the wall 2, the opening of the wall 2 then being covered by the first element 3.

In FIG. 3c, the second element 4 of the electrical connector 1 is ready to be inserted into the opening from the second face 22 of the wall 2, until its first body part of the second element 4 is housed in the barrel passing through the first element 3. The second body part is then opposite the second internal surface of the opening.

In FIG. 3d, the second element 4 is received in the final position in the opening and in the through housing of the first element 3. The electrical conductor 14, represented by two power pins in L 141, is then positioned opposite the housing through the second element 4 to be housed there.

Also shown are two signal pins 142 disposed between the two L-shaped power pins 141. These two signal pins 142 are configured to detect an opening of the electrical circuit formed by the external beam and the electrical component.

In FIG. 3e, a binding material is placed in the through housing, then the electrical conductor 14 is inserted into the through housing until the retention lugs extend transversely to the longitudinal axis X outside the through housing , for example. Advantageously, the electrical conductor 14 can be inserted into the through housing of the second element before the insertion of the second

0 element 4 in the opening of the wall 2, to be housed in the barrel passing through the first element 3.

In FIG. 3f, the fixing device 16 is arranged on an external surface 23 of the opening of the wall 2 opposite the second internal surface of the opening of the wall 2 and in abutment against the head 12 of the second element 4 The second element 4 is then

5 pressed against the second face 22 of the wall 2, in line with the opening which passes through the wall

2.

The locking device 16 is formed for example by a non-return clip. The non-return clip comprises an open metal ring 160 in which a hole 162 is formed in a projecting part 163. The open metal ring 160 is folded at each of its

0 ends to form two metal tabs 161 with spring effect. The open metal ring 160 comprises, at each fold forming the metal tabs 161, the curved portion 161a ensuring the spring effect, as described above.

The part of the metal ring 160 comprising the hole 162 is disposed on the external surface 23 of the opening of the wall 2 so as to bear against the head 12 of the second element 4. A screw is then inserted through the hole 162 in correspondence with a threaded hole 164 on the face 23 of the wall 2. The part of the metal ring 160 forms a part for fixing the non-return clip. The two metal tabs 161 of the metal ring 160 form an axial holding part of the non-return clip.

In the assembled state, the two metal tongues 161 with spring effect of the non-return clip are in abutment against the head 12 of the second element 4. In this way, the head 12 of the second element 4 is kept in abutment against the second face 22 of the wall 2 to ensure axial maintenance of the second element 4 in which the power pins L 141 are housed when they are secured to the printed circuit board 17. This attachment can be achieved by welding the power pins in L 141 on the printed circuit board 17.

In FIG. 3g, the second portions 141b of the L-shaped pins 141 extend in the direction of a printed circuit board 17 and are joined to it by welding, for example. The electrical connection between an external electrical harness to the electrical component and the printed circuit board 17 can thus be made by the electrical connector 1 mounted on the wall 2 described above.

Of course, the invention is not limited to the embodiments described and shown in the accompanying drawings. In particular, the electrical component can be:

- an electronic computer, the wall then being formed by a housing of this computer,

- a power module, in particular for supplying an electric propulsion motor of a motor vehicle,

- an inverter, in particular for a motor vehicle.

In the case of an application to an electric compressor, the wall is formed by the compressor housing and the electric connector 1 of the invention connects the control module of this electric compressor to an electric harness coming from the motor vehicle.

Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
