Description

Title of the invention: Electric charging socket with anti-electrification device

[0001] The present invention relates to the field of the automotive industry and more particularly to electrical charging systems for motor vehicles, such systems being installed on hybrid or electric vehicles.

[0002] These hybrid or electric vehicles generally comprise an electrical energy storage unit such as a battery, which makes it possible to supply the vehicle with the electrical energy to be transformed into mechanical power necessary for its drive by a powertrain. During operation of the vehicle, the energy stored in this battery decreases, and it then needs to be recharged by the user, for example by being regularly connected to an electrical network.

[0003] For this purpose, there is charging equipment such as wall terminals, also known as "Wallboxes", which allow the vehicle battery to be recharged. These wall terminals may comprise a charging cable intended to be connected to the vehicle via a connection terminal, for example an electrical charging socket, such an electrical charging socket being configured to cooperate with a complementary electrical socket of the hybrid or electric vehicle.

[0004] As soon as the electrical charging socket is connected to the wall terminal, the cable is capable of being crossed by an electric current, in particular up to the electrical pins of the electrical charging socket. The electrical charging socket may then present risks of electrification or electrocution, for example in the event of contact between a finger of a user of the electrical charging socket and an electrical pin thereof.

[0005] In this context, the present invention thus has as its main object an electrical charging socket for a motor vehicle, comprising a socket end piece with a connection face, an interface face and at least one cylindrical housing extending mainly in a longitudinal direction and passing through the socket end piece from the connection face to the interface face, the electrical charging socket comprising a holding cylinder arranged in the cylindrical housing and an electrical connection member arranged in the holding cylinder, one end of the electrical connection member being in the vicinity of the connection face, the electrical charging socket comprising an anti-electrification member associated with the end of the electrical connection member and comprising a peripheral portion and a membrane, the anti-electrification member being configured to have a protective position in in which the membrane is substantially planar and a connection position in which the membrane is deformed towards an interior of the holding cylinder.

[0006] The electrical charging socket according to the invention is intended for the electrical charging of a vehicle, more precisely an electric vehicle. It comprises a socket end piece which is a connection terminal, with on the one hand a connection face configured to cooperate with an electrical charging member of the vehicle, for example a complementary charging socket, and on the other hand an interface face configured to cooperate with a wall terminal, for example by means of a charging cable. The socket end piece is crossed right through by a cylindrical housing which receives a holding cylinder, itself receiving an electrical connection member. Such an electrical connection member is for example a pin for making electrical contact with a plug of the charging socket arranged on the vehicle.

[0007] An anti-electrification member is associated with the end of the electrical connection member; this means that it cooperates with it. This anti-electrification member comprises a peripheral portion which contributes to maintaining it in position relative to the holding cylinder, as well as a flexible and deformable membrane. Such deformation of the membrane allows it to take either a protective position, in which it forms a substantially flat disc and prevents possible contact between the electrical connection member and a finger of a user of the electrical charging socket, or a connection position, under the effect of pressure, in which it is capable of being crossed by the plug of the electrical charging member carried by the vehicle. In this connection position, the membrane is no longer flat; it deforms when the plug comes to bear against it, so as to extend towards an interior of the holding cylinder.

[0008] According to a characteristic of the invention, the anti-electrification member is arranged, in the longitudinal direction, between the holding cylinder and a wall of the cylindrical housing facing the end of the electrical connection member.

[0009] When the anti-electrification member is arranged between the holding cylinder and a wall of the cylindrical housing, this is a first embodiment of the electrical charging socket. In this first embodiment, the anti-electrification member is held by plating between these two elements.

[0010] According to an alternative characteristic of the invention, the anti-electrification member and the holding cylinder form a single-piece assembly.

[0011] This is a second embodiment, in which the anti-electrification member and the holding cylinder form a single piece which can for example be obtained by overmolding. In this case, the peripheral portion is formed by an inner wall of the holding cylinder.

[0012] According to one characteristic, the electrical connection member has a tubular shape with an internal face and an external face, the internal face being equipped with bosses configured to be in contact with a plug of an electrical charging member, the bosses being arranged at a distance from the end associated with the anti-electrification member.

[0013] According to a characteristic of the invention, in the connection position, the membrane is at a distance from the bosses.

[0014] It is understood here that there is a longitudinal offset between the bosses and the end with which the anti-electrification member is associated. Such an offset makes it possible to avoid contact between the bosses and the membrane when the latter is in the connection position, and thus to avoid any hindrance of the anti-electrification member between the bosses and the plug of the electrical charging member.

[0015] According to one characteristic, the membrane comprises slots configured to deform when the plug of the electrical charging member passes through.

[0016] The membrane more precisely comprises tabs which are separated from each other by slots. In the connection position, these slots deform and open so that the tabs move apart from each other, thus allowing the passage of the plug of the electrical charging member.

[0017] According to another characteristic of the invention, the membrane comprises a central opening, the slots extending in a star shape from this central opening.

[0018] Within the anti-electrification member, the membrane extends from the peripheral portion to the central opening. The slots extend from this central opening and towards the peripheral portion, and they are arranged at regular angles to each other in such a way that they have a star shape.

[0019] According to one characteristic, the slots widen as they move away from the central opening.

[0020] According to an alternative characteristic, the slots have a constant width as they move away from the central opening.

[0021] It is understood here that there are two distinct embodiments for the slots: a first embodiment in which they are increasingly wider going from the central opening to the peripheral portion, and a second embodiment in which their width remains unchanged regardless of the point where it is measured.

[0022] According to a characteristic of the invention, the slots define between them tongues articulated on the peripheral portion.

[0023] According to another characteristic of the invention, edges of the tabs which define the central opening are rounded.

[0024] The tabs are thus free from protruding edges which could hinder the insertion of the plug of the electrical charging member.

[0025] According to another characteristic, the membrane is made of rubber.

[0026] The membrane is thus made of a flexible and deformable material. Preferably, the rubber is a silicone rubber with a hardness of between 25 and 100 shore A.

[0027] According to a characteristic of the invention, the electrical charging socket comprises a plurality of holding cylinders in each of which an electrical connecting member is arranged, each holding cylinder being connected, on the interface face, to at least one other holding cylinder by a connecting tab.

[0028] The holding cylinders are thus arranged within the gripping endpiece in a spider web arrangement, each connecting tab being able to provide a junction between two or more holding cylinders. Such an arrangement requires additional machining, namely the formation of the connecting tab, but allows insertion of all the holding cylinders in a single assembly step and as such constitutes a time saving.

[0029] According to another characteristic, the connecting tab extends into a notch in the interface face.

[0030] This notch corresponds to a hollow portion of the interface face which extends between two neighboring holding cylinders.

[0031] The invention further relates to a method of assembling an electrical charging socket as described previously, comprising a step of inserting the anti-electrification member into the cylindrical housing of the socket end piece, a step of inserting the holding cylinder into this cylindrical housing and a clamping step during which the anti-electrification member is pressed by the holding cylinder against the wall of the cylindrical housing.

[0032] This assembly method corresponds to the first embodiment of the electrical charging socket, that is to say that in which the anti-electrification member is arranged between the holding cylinder on the one hand and the wall of the cylindrical housing on the other hand.

[0033] Alternatively, the invention relates to a method of assembling an electrical charging socket as described previously, comprising a step of overmolding the anti-electrification member with the holding cylinder, and a step of inserting an assembly formed by the holding cylinder and the anti-electrification member within the cylindrical housing of the socket end piece.

[0034] This alternative to the assembly method corresponds to the second embodiment of the electrical charging socket, namely that in which the anti-electrification member is arranged within the holding cylinder. Overmolding here makes it possible to avoid an assembly operation.

[0035] Other characteristics, details and advantages of the invention will emerge more clearly on reading the description which follows on the one hand, and examples of embodiment given for informational and non-limiting purposes with reference to the attached drawings on the other hand, in which:

[0042] The features, variants and different embodiments of the invention may be combined with each other, in various combinations, provided that they are not incompatible or mutually exclusive. In particular, variants of the invention may be imagined comprising only a selection of features described below in isolation from the other features described, if this selection of features is sufficient to confer a technical advantage and / or to differentiate the invention from the prior art.

[0043] In the figures, the elements common to several figures retain the same reference.

[0044] In the detailed description which follows, the terms “longitudinal”, “transverse” and “vertical” refer to the orientation of the electrical charging socket according to the invention. A longitudinal direction corresponds to a main extension direction of a cylindrical housing of the electrical charging socket, this longitudinal direction being parallel to a longitudinal axis L of a reference frame L, V, T illustrated in the figures. A vertical direction corresponds to a direction perpendicular to a ground on which rests a motor vehicle intended to be electrically recharged via the electrical charging socket, this vertical direction being parallel to a vertical axis V of the reference frame L, V, T and this vertical axis V being ... dicular to the longitudinal axis L. Finally, a transverse direction corresponds to a direction parallel to a transverse axis T of the reference frame L, V, T, this transverse axis T being perpendicular to the longitudinal axis L and to the vertical axis V.

[0045] Figures 1 and 2 thus illustrate, schematically, a perspective view of an electric charging socket 1 according to the invention. This electric charging socket 1 is intended to equip a hybrid or electric motor vehicle for the purpose of electrically recharging a battery which equips it.

[0046] The electrical charging socket 1 has a socket end 2 which extends longitudinally between a connection face 4, particularly visible in [Fig. 1], and an interface face 6, particularly visible in [Fig. 2]. The connection face 4 is configured to be connected to a complementary electrical charging member of the motor vehicle, while the interface face 6 is intended to be connected by a charging cable to a wall socket.

[0047] The socket end piece 2 has an internal space 8, which is delimited at the interface face 6 by a transverse wall 10. Conversely, the internal space 8 is open to an exterior of the electrical charging socket 1 at the connection face 4. Within the internal space 8 is arranged at least one cylindrical housing 12. This cylindrical housing 12 extends mainly in a longitudinal direction L. It passes through the socket end piece 2 from one side to the other, that is to say from the connection face 4 to the interface face 6.

[0048] More precisely, the electrical charging socket 1 here comprises seven cylindrical housings 12. There is thus a central cylindrical housing 12 around which are arranged, in a star, six other cylindrical housings 12. It is thus possible to define two upper cylindrical housings 12 which are arranged on the same longitudinal-vertical plane, three middle cylindrical housings 12, including the central cylindrical housing 12, which are arranged on the same longitudinal-vertical plane, and two lower cylindrical housings 12 also arranged on the same vertical longitudinal plane. The middle and lower cylindrical housings 12 have similar diameters, while the upper cylindrical housings 12 have reduced diameters.

[0049] As will be described more precisely hereinafter, the upper cylindrical housings 12 receive elements which participate in control functions during the electrical charging of the motor vehicle. The middle and lower cylindrical housings 12 receive elements dedicated to the transmission of a single-phase or three-phase electric current, or neutral or grounded elements. The characteristics which will now be described in relation to one of the cylindrical housings 12 are intended to apply, unless otherwise stated, to any one of the middle or lower cylindrical housings 12.

[0050] Within each cylindrical housing 12 is arranged a holding cylinder 14 extending mainly in the longitudinal direction L. This holding cylinder 14 receives an electrical connection member 16 of the electrical charging socket 1. The holding cylinder 14 is for example made of a plastic material, and it makes it possible to ensure that this connection member 16 is held in position within the socket end piece 2. Such an electrical connection member 16 takes for example the form of a pin intended to cooperate with a plug 17 of the complementary electrical charging member arranged on the vehicle, in particular by transmitting an electric current to it. Such a plug 17 of the electrical charging member is shown schematically in Figures 3 and 4.

[0051] At the interface face 6 and as illustrated in [Fig. 2], the holding cylinders 14 are connected to each other by means of connecting tabs 18, which are material extensions of these holding cylinders 14. More precisely, each of the holding cylinders 14 is connected to at least one other holding cylinder by means of such a connecting tab 18. The holding cylinder 14 arranged in the central cylindrical housing 12 is for example connected to four other cylindrical housings 12 by four connecting tabs 18, while the holding cylinders 14 of the lower cylindrical housings 12 are respectively connected by three connecting tabs 18 to three other cylindrical housings 12.Each connecting tab 18 extends into a notch machined for this purpose in the interface face 6, and more particularly in the transverse wall 10 of this interface face 6, so that the connecting tab 18 does not protrude relative to the transverse wall 10. The connecting tabs 18 here connect the holding cylinders 14 in a spider web arrangement.

[0052] The electrical connection member 16 extends within the holding cylinder 14 between a first end 20 facing the connection face 4 and a second end 22 facing the interface face 6. As is particularly visible in FIGS. 3 and 4, which are sectional views of the electrical charging socket 1, the electrical connection member 16 is in the form of a tube. This electrical connection member thus has an external face 24 in contact with the holding cylinder 14 and an internal face 26 opposite the external face 24. The internal face 26 is deformed so as to have bosses 28, which are configured to come into contact with the plug 17 of the electrical charging member of the vehicle to transmit an electric current thereto. Such bosses 28 are closer to the first end 20 than to the second end 22, but are nevertheless arranged at a distance from this first end 20.

[0053] According to the invention, the electrical charging socket 1 comprises an anti-electrification member 30. Such an anti-electrification member 30 has the role of preventing electrification or even electrocution which would result from contact between the bosses of one electrical connection members 16 and a finger of a user of the electrical charging socket 1, without however hindering the passage of the plug 17 of the electrical charging member of the vehicle.

[0054] The anti-electrification member 30 is for this purpose associated with the first end 20 of the electrical connection member 16. Such an association can result, depending on the embodiments, either in a pressing against this first end 20, or in an overmolding within it. There is in fact a first embodiment of the electrical charging socket 1 in which the anti-electrification member 30 is arranged, in the longitudinal direction, between the holding cylinder 14 and a wall of the cylindrical housing 12. Such a wall is here a transverse wall 31 of the cylindrical housing 12 at the level of the connection face 4, which faces the first end 20 of the electrical connection member and which is substantially parallel to the transverse wall 10 of the interface face 6. It is understood that in this first embodiment, the anti-electrification member 30 is sandwiched between the transverse wall 31 and the holding cylinder 14.Such a first embodiment is particularly visible in Figures 3 and 4. Alternatively, in a second embodiment not shown here, the anti-electrification member 30 and the holding cylinder 14 can form a single-piece assembly. In this case, the anti-electrification member 30 and the holding cylinder 14 are overmolded with each other so as to form a single piece.

[0055] The anti-electrification member 30 will now be described in relation to Figures 5 and 6, which illustrate different configurations and different embodiments. The anti-electrification member 30 is disc-shaped and comprises a peripheral portion 32 forming a bulge which surrounds a membrane 34. Such a membrane 34 has a diameter substantially equal to a diameter of the electrical connection member 16. It is made of a flexible and deformable material, for example rubber. This rubber is preferably a silicone rubber whose hardness is between 25 and 100 shore A. The peripheral portion 32 contributes to maintaining the anti-electrification member 30 in position, whether against the holding cylinder 14 in the first embodiment of the electrical charging socket 1 or within the holding cylinder 14 in the second embodiment.In this second embodiment, the peripheral portion 32 can also be formed, at least partially, by an inner wall of the holding cylinder 14.

[0056] The membrane 34 comprises elastic tabs 36 which have a substantially triangular shape. These elastic tabs 36 are articulated on the peripheral portion 32; in other words, they extend from this peripheral portion 32. They thus have an edge which is connected to the peripheral portion 32, and a free edge 38 of rounded shape, which defines within the membrane 32 an opening central opening 40. Such a central opening 40 corresponds to a light within the membrane 32. From this central opening 40 extend slots 42 which delimit two adjacent elastic tabs 36. It is thus understood that a shape of the elastic tabs 36 depends on the cutting of the slots 42 and their arrangement within the membrane 34. These slots 42 extend here in a star shape from the central opening 40, in the direction of the peripheral portion 32 without however being in contact with the latter.

[0057] Figures 5 and 6 correspond to two distinct embodiments of the slots 42, with respectively a first embodiment shown in [Fig.5] and a second embodiment illustrated in [Fig.6]. In their first embodiment, the slots 42 have an increasing width as they move away from the central opening 40; in other words, these slots 42 are thinner near the central opening 40 than near the peripheral portion 32. Conversely, in their second embodiment the slots 42 have a constant width. Whether in their first embodiment or in their second embodiment, the slots 42 have rounded ends, which allows better articulation of the elastic tabs 36 and limits the risks of tearing of the membrane 34 at this location.

[0058] Such an articulation of the elastic tabs 36 is important because the anti-electrification member 30 is deformable so as to alternate between two positions, both illustrated in [Fig. 5]. The anti-electrification member 30 thus has a protection position 44 or rest position, which prevents contact between a user's finger and one of the electrical connection members 16 of the electrical charging socket 1. In this protection position 44, which is also visible in [Fig. 1], the membrane 34 is substantially flat. This means that the peripheral portion 32 and the central opening 40 are substantially arranged in the same plane. The anti-electrification member 30 can also take a connection position 46 or constraint position, also shown in FIGS. 3 and 4, which allows electrical contact between the electrical connection member 16 and the plug 17 of the electrical charging member of the vehicle.In this connection position 46, the membrane 34 is deformed so as to extend at least partially towards an interior 48 of the holding cylinder. Such deformation results from pressure exerted by the plug 17 during its passage through the central opening 40. It is understood that in this connection position 46, the membrane 34 is no longer flat; the slots 42 deform and open as the plug 17 passes, thus contributing to a separation of the elastic tabs 36 relative to each other and to their extension inside 48 of the holding cylinder, in the direction of the second end 22, as is particularly visible in [Fig. 4]. The free edges 38. elastic tabs 36 which border the central opening 40 being, as mentioned previously, of rounded shape, the insertion of the plug 17 through this central opening 40 is facilitated.

[0059] As illustrated in Figures 3 and 4, which are respectively a view in which the plug 17 is partially inserted through the central opening 40 and a view in which this plug 17 is in contact with the bosses 28 after having been completely inserted, in the connection position 46 the membrane 34 and in particular its elastic tabs 36 are at a distance from the bosses 28. There is in fact a longitudinal offset between these bosses 28 on the one hand and the first end 20 with which the anti-electrification member 30 is associated. Such a longitudinal offset makes it possible to avoid interference by the anti-electrification member 30 between the bosses 28 and the plug 17 of the electrical charging member of the motor vehicle, which would disrupt the transmission of the electric current and even more so the recharging of the vehicle.Thus, when the plug 17 is pushed through the central opening 40 of the membrane 34, the elastic tabs 36 of this membrane 34 deform and come to rest against the internal face 26 of the electrical connection member 16, the longitudinal offset ensuring that they are, in doing so, not in contact with the bosses 28.

[0060] A method of assembling the electrical charging socket 1 according to the invention will now be described, for each of the two embodiments mentioned above.

[0061] In the first embodiment, which is the one for which the anti-electrification member 30 is arranged between the holding cylinder 14 and the transverse wall 31 of the cylindrical housing 12, the assembly method is preceded by a step of manufacturing the anti-electrification member 30 so that its slots 42 are either of increasing width as in their first embodiment, or of constant width as in their second embodiment. The assembly method comprises a step of inserting this anti-electrification member 30 into the cylindrical housing 12 of the grip end piece 2, then a step of inserting the holding cylinder 14 into this cylindrical housing 12. In the presence of a plurality of holding cylinders 14, the insertion step will be completed when the connecting tabs 18 of these holding cylinders 14 come into abutment against the notches provided to receive them on the transverse wall 10 of the interface face.The holding cylinders 14 will also be in abutment against the anti-electrification member 30, itself bearing against the transverse wall 31. The assembly method subsequently comprises a tightening step, during which the anti-electrification member 30 is pressed by the holding cylinder 14 against the transverse wall 31 of the cylindrical housing 12. Such a tightening step makes it possible to ensure that there is no play between the transverse wall 31 and the anti-electrification member 30 on the one hand, and . between this anti-electrification member 30 and the holding cylinder 14 on the other hand. The assembly method then comprises a step of inserting the electrical connection member 16 into its holding cylinder 14, the latter then being able to come into contact, via its bosses 28, with the plug 17 of the electrical charging member of the motor vehicle to transmit to it the electric current necessary for its recharging.

[0062] In the second embodiment, which is the one for which the anti-electrification member 30 and the holding cylinder 14 form a single piece, the assembly method comprises a step of overmolding this anti-electrification member 30 and this holding cylinder 14. In the same way as for the first embodiment, the anti-electrification member can be produced either with slots 42 of increasing width, as is particularly visible in [Fig. 5], or with slots 42 of constant width, as illustrated in [Fig. 6]. The assembly method then comprises a step of inserting the single-piece assembly thus formed by the anti-electrification member 30 and the holding cylinder 14 into the cylindrical housing 12 of the socket end piece 2, then an insertion step during which the electrical connection member 16 is itself inserted into the single-piece assembly.The plug 17 can then be inserted through the anti-electrification member 30 to come into contact with the bosses 28 of the electrical connection member 16, and thus allow the vehicle to be electrically recharged.

[0063] The present invention thus proposes an electrical charging socket having an anti-electrification member, which makes it possible to create a physical barrier between an electrical connection member of the electrical charging socket and a user's finger, without however hindering the electrical contact between this electrical connection member and a plug of an additional electrical socket of a motor vehicle.

[0064] The present invention cannot, however, be limited to the means and configurations described and illustrated here and it also extends to any equivalent means and configuration as well as to any technically effective combination of such means.
