    [0001] TECHNICAL FIELD The field of the invention is that of electrical connectors comprising a male electrical socket and a female electrical socket, the male electrical socket being able to be the electrical socket of a trailer hitch. The invention more particularly relates to a female electrical socket comprising an orifice defined by an annular inner wall and a bottom in which is intended to insert axially a corresponding male plug, several electrical contacts disposed in the orifice and a closing shutter the orifice in the absence of a plug in the socket. Prior art It is known that a trailer hitch is hooked to the rear of a towing vehicle via a towing hook attached to the vehicle body. When the coupling of the trailer is hooked to the vehicle, the light signals such as the turn signals, the brake or reversing lights of the rear of the vehicle are hidden by the trailer and a transfer of these light signals from the towing vehicle to the trailer must be made through an electrical connector comprising a socket generally attached to the towing vehicle and a male electrical plug connected by an electric cable to the trailer lights. There are now coupling hooks that are removable so that they do not protrude from the rear of the vehicle in the absence of the trailer. Nevertheless, the electrical socket of the electrical connector is not removable, it remains visible at the rear of the towing vehicle in the absence of the trailer, making its presence unattractive. Therefore, it is sought to arrange the female electrical socket so that it is least visible from the rear of the towing vehicle when the trailer is not hooked to the motor vehicle. In general, the electrical coupling between the male electrical outlet and the female electrical outlet is via pin electrical contacts of the plug which engage by friction in metal blade electrical contacts housed in the housing. 'hole of the female electrical socket. Trailer or caravan users find that inserting the movable plug into the fixed socket opening, which is usually horizontal translation, is often tricky. In addition, when the trailer hitch is not hooked to the rear of the towing vehicle, the electrical contacts of the socket outlet, if not protected, may be damaged by being subjected to environmental conditions such as as the intrusion of moisture and dirt. To protect the electrical contacts from the female electrical socket, a shutter can be positioned on the socket of the socket as described in patent documents WO01997012784 or US7125269. In these published patent documents, the shutter is a flip cap that must be lifted before inserting the male electrical plug into the female electrical socket. The shutter can also be constituted by one or more cover flaps pivotally mounted and which automatically fold back by rotation in front of the electrical contacts to prevent access when disconnecting the two male and female, such as such as described in the patent document FR2685981. EP2269845 also proposes to protect the electrical contacts of the socket by electrically insulating them with an insulating molding material. Nevertheless all these types of shutters have either a mechanical complexity or a manufacturing complexity. DESCRIPTION OF THE INVENTION The object of the invention is to remedy these drawbacks by proposing another type of electrical connector for connecting for example a hitch, in particular a trailer hitch, to a towing vehicle, notably a motor vehicle such as a car. . The basic idea of the invention is to propose a female electrical socket intended to be fixed discretely under the body of the towing vehicle by orienting the orifice of the female electrical socket in the direction of the ground. To this end, the subject of the invention is a female electrical socket, comprising an orifice defined by an annular inner wall and a bottom in which is intended to axially insert a corresponding male electrical socket 25, several electrical contacts arranged in the orifice and a shutter which closes the orifice in the absence of a male electrical socket in the female electrical socket, characterized in that the electrical contacts are lamellar contacts disposed on the surface of the annular wall of the orifice, that the shutter has a surface which is curved and in that the curved surface shutter is mounted to move axially in the orifice, a return spring being provided between the bottom of the orifice and the shutter for oppose the axial displacement of the shutter towards the bottom of the orifice during the insertion of the male electrical plug into the socket. With such an arrangement, the insertion of the male electrical plug can be done transversely to the longitudinal direction of the vehicle, that is to say from the bottom upwards thus allowing to conceal the female electrical socket under the body of the vehicle. The attachment of the female electrical outlet can be made 10 flush with the rear bumper of the vehicle, so that the socket does not protrude from the underside of the vehicle and so it is not visible. With such an arrangement, there is in addition a female electrical outlet which is always closed by a shutter 15 when the electrical plug is not inserted into the socket, thus protecting the electrical contacts of the electrical socket from environmental conditions. which are in the gap space of the female electrical socket. The curved surface obturator may be cup-shaped with a circular contour, the bending being in the center of the cup. The shutter could also have an angular shape, for example with a square, rectangular or triangular contour and with a pyramidal bending in the center. The female electrical socket according to the invention may advantageously have the following particular features: the electrical lamellar contacts each extend in the axial direction of insertion of the male electrical plug into the female electrical socket; - Each lamellar electrical contact is arranged to be wired by lug. The invention extends to an electrical connector, characterized in that it comprises a female electrical socket and a male electrical socket arranged to fit axially into the orifice of the female electrical socket. The electrical connector according to the invention may advantageously have the following particulars: the male electrical socket comprises a connection pad defined by an annular outer wall and a head, this connection pad comprising a plurality of lamellar electrical contacts arranged on the surface of the external annular wall of the connection pad, the head of the connection pad having a curved surface complementary to the curved surface of the shutter of the female electrical socket; - The electrical contacts of the male electrical outlet are slatted with a spring area; the connection pad and the orifice have complementary cylindrical annular surfaces; a tongue and groove keying system is provided arranged on the male electrical socket and the female electrical socket; the female electrical socket and the male electrical socket comprise a magnetic mutual attraction system; - there is provided a locking system for locking the male electrical socket in axial position in the socket; - The male electrical outlet has a handle, the pull being arranged in the grip handle; - The male electrical outlet is a towing hitch including trailer; - The curved surface of the shutter is curved towards the inside of the hole of the socket.
    [0002] With all these features, we get an electrical connector that includes a female electrical outlet that can be hidden behind a towing vehicle, and whose electrical contacts are well protected in the absence of a plug in the socket female electric. In an electrical connection according to the invention, there is a first polarizer constituted by the curved surface of the shutter of the female electrical socket and the curved surface of the head of the stud of the male electrical socket. Furthermore, there is a second polarizer constituted by the tongue and groove system. It can be understood that even without visual inspection of the socket, the user will first be able to easily and quickly position the plug of the plug at the entrance of the socket opening by seeking by a tactile control the coincidence of the convex surface of the plug head of the plug with the curved surface of the plug of the socket. From this coincidence, the user will be able to rotate axially the plug in the socket to achieve a coincidence of position between the groove, for example on the plug, and the tab on the socket. It will also be helped to obtain this coincidence by the fact that normally, in the coincidence position, the handle of the plug will be oriented along the longitudinal axis of the vehicle. After the groove is made to coincide with the tongue, the insertion of the plug into the socket will be made all the more easily as the magnet system will draw the plug and the socket towards each other. socket.

    [0004] DESCRIPTION OF THE EMBODIMENTS In FIG. 1, there is schematically illustrated an example of an electrical connector according to the invention which here comprises a female electrical socket 1 intended to be fixed under a box of a motor-driven towing vehicle (not shown ) and a plug 2 that fits in the direction of the arrow F in the female electrical socket 1, from the bottom to the top, from below the body of the towing vehicle. Figure 2 schematically illustrates the plug 2 inserted and locked in the female electrical socket 1. Figures 1 and 2 show numerical references which will be discussed later in the description. Figure 3 shows an exploded view of the female electrical socket 1. It is shown here in several parts which fit into each other. It consists of a housing 3, shown in Figure 1, molded plastic for example. This housing comprises a cover 4 with a circular central hole 15, a grip body 5 with a bore and an annular cage 6 inserted into the bore of the grip body 5. The grip body 5 and the cage 6 form a orifice 7 with a bottom. A cover 8 with a circular central hole engages in the socket body 5. Metal lamellar electrical contacts 9 are arranged inside the annular wall of the cage 6. Each lamellar electric contact 9 is wired by standard crimp lug. In the case of example 13 metal strips are arranged around the cage 6. A shutter 10 closes the orifice 7. The shutter 10 is here in the form of a circular cup with a curved surface towards the inside. It is understood that the curved surface is defined as a surface having a salient top (or a hollow) and may be in a form different from that of a circular cup, such as a pyramidal shape. for example.
    [0005] The shutter 10 is mounted to move axially in the orifice 7 by a return spring 12 which surrounds a piston 11 extending from the internal face of the shutter 10 towards the bottom of the cage 6.
    [0006] Magnets 24, 24 'and 24 "are arranged at the periphery of the socket body 5. In FIG. 4, an exploded view of the male electrical plug 2 is shown. It comprises a plastic shell for example, which comprises several parts assembled to define a gripping handle of the male electrical plug 2, a connection pad 13 formed of a cylindrical stud with an annular outer surface defining a kind of cage receiving on its outer surface electrical contacts 14 with a strip Each lamellar electrical contact can be wired with a standard crimp terminal The head 15 of the connection pad 13 has an outwardly curved surface, here a curved disk.
    [0007] This connection pad head 13 has a shape complementary to the curved surface shutter 10, here in the form of a circular cup curved towards the outside of the socket of the male electrical socket. It is understood that the direction of bending of the curved complementary surfaces 25 could be reversed without changing the scope of the invention. In the case of example in FIG. 4, there is illustrated a connection pad head 13 with thirteen electrical contacts 14 according to the ISO 11446 standard. The shell of the male electrical plug 2 comprises two half-shells 16 and 16. which form the gripping handle and a support 17 of connection pad 13 in which is arranged a locking system, here pull tab 18, which controls two connecting rods 19 and 19 'which extend in retracted position in the stud of connection 13 or advanced protruding from the connection pad 13 in two slots 23 arranged perpendicularly to the longitudinal axis of the connection pad 13. Magnets 20, 20 'and 20 "are arranged in the support 5 17 of the connection pad 13, at the periphery of the support 17. The support 17 of connection pad 13 fits into the two half-shells 16 and 16 'and a housing is provided in the handle to move longitudinally the pull tab 18 of a locking position or rest to a e 10 unlock position. When the pull tab 18 is at rest the rods 19 and 19 'are in the advanced position in the slots 23. When the pull tab 18 is in the unlocking position by action of the user on the pull tab 18, the rods 19 and 19' are in the retracted position in the connection pad 13. In Figure 5 there is shown a bottom view of the female socket 1 showing the parts described above nested. On the female electrical socket 1, 20 shown here without the shutter 10, it is possible to visualize the electrical contacts 9 each extending in the axial direction of the orifice 7. A groove 21 extends axially along the cage 6 from the cover 8 of the socket 1. In Figure 6 there is shown a top view of a portion of the plug 2 showing the electrical connection pad 13 assembled in the support 17 and the head 15 of connection pad 13 having a curved surface complementary to the curved surface of the shutter 10. A tongue 22 extends axially along the annular outer surface of the connection pad 13. This tongue 22 has a shape complementary to the groove 21 of the female electrical socket 2.
    [0008] In FIGS. 5 and 6, the housings of the magnets 24, 24 ', 24 "arranged in the socket body 5 of the female electrical socket 1 and the housings of the magnets 20, 20', 20" arranged in the support 17 of the stud 13 are distinguishable by circles at the peripheries of the two elements 5 and 17. The magnets 24, 24 ', 24 "and 20, 20', 20" are positioned so as to attract each other during the insertion of the male electrical plug 2 in the female electrical socket 1. In FIG. 7, the electrical lamellar contacts 9 of the cage 6 of the female electrical socket 1 making contact with the electrical contacts 14 with the lamella of the socket are shown schematically. 2. The electrical contacts 14 may have a spring area 15 which ensures good electrical contact between the lamellae of the respective electrical sockets. The female electrical socket 1 according to the invention can be fixed flush with the rear bumper of the vehicle, under the vehicle body, so as not to be visible from the rear of the vehicle. The electrical connector according to the invention therefore comprises a male electrical socket 2 arranged to fit axially easily in the orifice 7 of the female electrical socket 1 without visual control. Particularly when the female electrical socket 1 is fixed under the body of the motor vehicle that will tow the trailer, the insertion of the male electrical plug 2 of the trailer into the female electrical socket 1 can be "blind" That is, without the user having to put his head under the vehicle. In the absence of a male electrical plug 2 in the female electrical socket 1, the shutter 10 closes the orifice 7 of the female electrical socket 1. The peripheral outer surface of the shutter 10 is in a flush position with the orifice 7 protecting thus the electrical contacts 9 disposed on the annular wall of the orifice 7 of the female electrical socket 1. The shutter 10 moves in axial translation 5 only during the insertion by the user of the male electrical plug 2 in the female electrical socket 1, thereby automatically appearing electrical contacts 9 to the lamella of the orifice 7 of the female electrical socket 1. Thus it is not necessary 10 to remove a protective cover of the female electrical socket 1 prior to 2. In accordance with the invention, the positioning of the connection pad 13 facing the shutter 10 is first of all facilitated by mechanical guidance by means of the curved shape of the head 15 of the connection pad 13 of the male electrical socket 2 which is complementary to the curved surface of the shutter 10 of the female electrical socket 1. The user holding the male electrical plug 2 by its handle gripping will move the plug 2 without having to look under the vehicle until it feels the interlocking of the two curved surfaces complementary to each other. Then the meeting of the tongue 22 with the groove 21 simply ensures that the head 15 of the connection pad 13 is positioned correctly facing the orifice 7. It will then be understood that the user can push the connection pad 13 of the male electrical socket 2 on the shutter 10 of the female electrical socket 1. The shutter 10 mounted to move axially in the orifice 7 is moved axially by the head 15 of the connection pad 13 towards the bottom of the orifice 7, the return spring 12 being compressed towards the bottom of the orifice 7.
    [0009] The insertion of the head 15 of the connection pad 13 into the orifice 7 is facilitated by the cylindrical complementary annular surfaces of the connection pad 13 of the male electrical plug 2 and the orifice 7 of the female electrical socket 1. Au during the insertion of the connection pad 13 of the male electrical socket 2 in the orifice 7 of the female electrical socket 1, the electrical contacts 9 and 14 with lamella arranged on the cages formed by the cylindrical annular surfaces, come into contact by friction. According to the invention, the tongue 22 sliding by translation in the groove 21 of complementary shape prevents the rotation of the connection pad 13 in the orifice 7.
    [0010] When the support 17 of the connection pad 13 of the plug 2 is close to the cover 8 of the socket 1, the magnets 24, 24 'and 24 "arranged in the periphery of the socket body 5 of the socket 1 female electrical attract the magnets 20, 20 ', 20 "arranged in complementary position in the periphery of the support 17 of connection pad 13, thus forming a mutual attraction system and a magnetic connection to flatten the taps against each other the other and facilitate the connection of the two sockets.
    [0011] It is understood that this magnetic connection gives way when the user exerts on the handle of the male electrical socket sufficient axial traction to disconnect the male electrical outlet. This axial traction is generally relatively low.
    [0012] Instead of or in addition to a connection by magnetic attraction, provision could be made for a connection by suction or snap-fastening. The support 17 of connection pad 13 of the male electrical socket 2 then being in abutment of the cover 8 of the female electrical socket 1, the user can lock the connection pad 13 in the orifice 7 by actuating the pull tab 18 of the locking system housed in the handle, from its unlocking position to its locking position. The rods 19 and 19 'are then in the advanced position so that they protrude into the cage 6 of the female electrical socket 1. The axial translation of the male electrical plug 2 into the female electrical socket 1 is then 10 blocked . It is understood that the locking system can be as a button to press or a wheel to turn. One could also control the proper locking by adding to the locking system a tactile and / or visual indicator. According to the invention the electrical contacts are distributed at the periphery of the two cages, internally for the female electrical socket 1 and externally for the male electrical socket 2. The electrical connection according to the invention 20 is not done by a pin insertion which is often delicate to fit in the orifices a catch. The lamellar electric contacts of the male 2 and female 1 electrical sockets according to the invention extend in the axial direction of insertion of the male electrical socket 2.
    [0013] The electrical contacts of the male electrical socket 2 slide along the electrical contacts of the female electrical socket 1. At the end of insertion of the connection pad 13 into the orifice 7, the good contacting of the electrical contacts 9 and 14 It is ensured by the choice of using spring-loaded sipes for the electrical contacts 14 of the male electrical socket 2. It goes without saying that the present invention can not be limited to the foregoing description of one of its embodiments, may undergo some modifications without departing from the scope of the invention.
