    [0001] Field of the Invention The present invention relates to a motor-driver module comprising an electric motor and a geared motor housing with an electronic interface for receiving an electronic module inserted in the direction of insertion into the electronic interface comprising walls, spaced apart from each other and forming, in combination with the electronic module, a closed electronic box for the electronic circuit. The invention also relates to a method of mounting an electronic module on a geared motor module. State of the art There are already known different drive devices comprising a separate electronic module which is coupled to the housing of the drive device. Document DE 200 04 338 A 1 shows, for example, a drive device comprising an electric motor housed in a transmission housing in the geared motor housing in which an insertable module slides. The insertable module has a front surface with a connector on its outer side and a circuit board on its inner side. The plate is lined with electronic components and motor contacts for the power supply of the motor. One finger of the circuit board has a SMD Hall sensor (surface mounted) and, in the installed state, cooperates with an annular magnet carried by the armature shaft. EP1618645B1 discloses a power unit whose electronic interface receives different electronic modules. To hold and hang the electronic modules, their radially opposite end to the rotor shaft has a radially extending radially protruding into the region of the electronics housing. This radial extension which is only necessary for the mounting of the electronic module constitutes an additional bulk, whereas in applications in the automotive field, the space available is often very limited. In addition, it is likely that inserting the electronic module, it clings to the guide rail so that the tightness of the electronic unit will not be guaranteed.
    [0002] DESCRIPTION AND ADVANTAGES OF THE INVENTION The object of the present invention is to overcome the drawbacks of known solutions and to provide a geared motor module comprising an electric motor and a geared motor housing with an electronic interface for receiving an electronic module inserted in the interface. in the direction of insertion and the electronic interface comprises walls, spaced apart from each other and which form, in combination with the electronic module, a closed electronic box for the electronic circuit, this module being characterized in that that, the outer wall of the electronic module comprises a recess in the direction of insertion having a gripping geometry for the robot fingers ensuring the automatic mounting of the electronic module in the electronic interface. The gearmotor module according to the invention has the advantage, vis-à-vis the state of the art, that by producing a geometry measurement for the mounting robot in the electronic box, the whole gearmotor module will be more compact. Any additional retention fastening element is removed from the direction of insertion and would lengthen the electronic module. The realization of the geometry of the plug in the form of an open recess in the outer radial wall of the electronic module allows the robot finger to insert very precisely the electronic module and very quickly in the interface. According to another particularly advantageous characteristic, the recess has two opposite engagement surfaces, against which a robot finger rests for mounting, the gripping surfaces being made in particular as the inner side of the spaced walls against which the fingers are locked. of robot. The robot fingers may be locked against the lateral bearing surfaces which are preferably the inner walls of the cavity. This allows the robot fingers to move away from the opposing bearing surfaces. Alternatively, the robot fingers may take a radial extension into the cavity. Particularly advantageously, axial centering surfaces are made in the recess with respect to the axial direction of the electric motor to axially center the robot fingers during their insertion into the cavity. Thus the guides of the electronic module arrive exactly in the guide rails of the interface. The axial side walls may have a slope or a conical shape. If the sealing surfaces of the electronic interface are formed to form with the joints of the first and second surfaces of the electronic module (insertion module) inclined relative to each other, radial sealing relative to the insertion direction, this sealing effect will be ensured independently of the thrust in the direction of insertion. Particularly advantageously, along the edge of the opening of the electronic interface, in the direction of insertion, there are guide rails for the electronic module through which the radial seal is pressed against the sealing surfaces. formed by the inner wall of the electronic interface. This prevents the relatively flexible walls of the electronic interface from escaping laterally when the electronic module is inserted and no longer makes it possible to seal the interface. At the same time, the axial extensions, folded, formed, stabilize the walls of the electronic interface and also serve as mechanical attachment of the electronic module, even in the case where there is no seal. For the electrical contact of the electronics, the second surface has an electrical passage in the axial direction which contacts the circuit board with the connector pins housed in the peripheral, outer axial side connector skirt. If the two surfaces whose front faces comprise the peripheral radial seals of the electronic module form between them an angle of between approximately 92 ° and 115 °, then, during assembly, it will be sufficient to exert a significantly reduced insertion force in the direction - Insert insertion because the radial seal will be pushed just before the final position of the electronic module in its final position, with the setpoint force, radially against the corresponding sealing surfaces.
    [0003] To stabilize the insertion module, a frame element can be provided between the first and second surfaces of the insertion module and the electronic module forms a quadrangular window before mounting the circuit board by the side. This makes it possible to make the electrical contacts directly on the frame element which, in the inserted position, is completely received by the electronic interface. The frame also advantageously comprises different abutment and / or guide surfaces with which the insertion module is applied in the final mounting position against corresponding complementary surfaces of the electronic interface. To facilitate automatic mounting, at least one of the bearing surfaces will have a shape of insertion cone so that the insertion module automatically finds its exact position more easily. The bearing surfaces / conical surfaces can be made in the axial direction and also in the direction of insertion. According to a preferred development, the recess is outside the sealed internal volume of the electronics, but nevertheless, inside the outer walls of the electronic box. For this purpose, advantageously, a front face of the second surface of the electronic module comprises a seal bearing against the corresponding sealing surfaces of the electronic interface. At a distance from this surface is a bottom surface for the connector skirt so that in the meantime, there will be a closed cavity. Since the second surface is preferably an angle greater than 90 ° radially to the first surface (and thus a corresponding complementary angle smaller with the bottom surface of the connector skirt), the developed volume preferably has a wedge shape. The bottom surface of the connector skirt constitutes the outer wall of the electronics housing and the bottom surface surrounds the wedge-shaped cavity with the corresponding wall portions of the walls spaced apart from the interface. The bottom surface extends substantially perpendicular to the connector skirt and within the connector skirt, a base receives the connection pins. This cavity provides enough room to attach the attachment elements and the complementary latching elements and at the same time to achieve the cavity used by the mounting robot. The cavity is oriented transversely to the direction of insertion by means of other housing walls or guides / rails which interpenetrate. The pedestal extends from the inner side of the connector skirt in the axial direction through the second surface with a radial seal so that the pedestal forms a passage for the connector pins to the circuit board. In the axial cavity between the bottom surface and the second surface, the base comprises complementary attachment elements of the electronic module which, when inserted into the electronic interface clings to the attachment elements. As the base also projects radially from the cavity area, the robot fingers can be advantageously inserted into the recess on both sides of the base which can then be gripped by the robot fingers. The robot fingers can be tightened away from the base in the direction of insertion or the robot fingers can tighten the base. The base may advantageously have bearing surfaces that come directly against the hooking elements once the complete insertion is made with the complementary surfaces of the electronic interface or directly on the hooking elements. The snap connection in the control unit ensures that the electronic module can not be detached from the electronic interface without destruction. When the electronic module is inserted in the electronic interface, these two elements are indissociable which makes it possible to verify if the electronic circuit is still as in the initial state, at the end of manufacture or if it has been manipulated in an unauthorized way . The housing portions of the electronic module with the housing parts of the electronic interface constitute a completely closed housing for the electronics. In a particularly economical and reliable manner, the hooking elements are hooks that hook by clipping into the eyelets latches or matching latches. In order for the hooks to hook securely into the corresponding complementary hooking elements, these hooks are connected to housing parts by elastic branches. In a particularly advantageous manner, these elastic branches extend in the direction of insertion which then, when mounting the electronic module are automatically spaced to return safely in the fastening elements corresponding to the end of the snap movement .
    [0004] The inclined arrangement of the second surface of the electronic module causes the wedge-shaped cavity to be outside the sealed electronic circuit. Thus, this second surface is the bottom surface of the connector skirt and the passage formed thereon for insertion, constitutes the limits to the cavity in the axial direction.
    [0005] To limit radially the cavity in the direction of insertion, its bottom comprises a partition which separates the open radial cavity receiving the robot fingers and the closed interior volume receiving the connection by hooking. Thus, the bonding connection is protected against manipulation. Mounting the cavity wall allows to predefine the penetration depth of the robot. The pedestal extends from the interior volume of the snap connection through the septum into the cavity because the connector pins are to be passed throughout this area relative to the connector skirt. For the fully automatic mounting of the electronics module with the robot, the guide rails and guides have ramps or inclined surfaces facilitating the insertion of the electronic module into the electronic interface both with respect to the direction axial and vis-à-vis the width of the electronic module. If the side walls of the electronic interface are slightly conical, radially with respect to the rotor shaft (with a small relative angle, less than 5 °), the electronic module, in particular with a formed joint, can be introduced more easily into the electronic interface because it is only in the last part of the insertion stroke that there will be a stronger friction between the seal and the sealing surface. Similarly, the sealing area during insertion can be pressed as an axial seal against the wall of the housing facing the pole. The two branches preferably form between them an angle of between 170 ° and 178 °. Thus, the insertion force required increases continuously directly before the abutment, which allows to have a defined axial seal.
    [0006] According to a preferred development, inside the electronic interface the housing part of the geared motor module comprises a radial recess relative to the armature shaft through which the circuit board can slide in the insertion module. The circuit board may be installed tangentially or radially with respect to the armature shaft, for example also with a larger extension in the axial direction but also in a plane perpendicular to the armature shaft. Thus, it will be possible to position sensor elements in the immediate vicinity of the armature shaft or on a sensor element installed on the armature. If the insertion module has a circuit board that slides into a recess of the transmission housing, the installation of the sensor system to enter the speed of rotation can be done in a simple way for an exact capture of the position of the device adjustment drive. The exact positioning of the sensor system formed for example by two Hall sensors, will be provided by the side walls and the guide rails of the electronic interface. The invention also relates to a method for mounting an electronic module in an electronic interface of a geared motor module, this method being characterized in that to insert the electronic module into the electronic interface, all first penetrate the robot fingers in a hollow of the outer wall of the electronic module and they are blocked there, then the robot fingers introduce the electronic module in the direction of insertion to at least one stop in the interface This electronic interface has resilient latching members that engage complementary latching members formed on the electronics module and the robot fingers are detached from the recess without requiring installation of other means. link between the electronic module and the electronic interface. Thus, the manufacturing method according to the invention makes it possible to insert the robot fingers into the radial cavity of the electronic module and to hold it securely. Then, the electronic module is inserted by the robot during an operation in the electronic interface and at the same time it is hooked; the hooking operation can not be observed from the outside. The electronic module will be inserted very precisely and at high speed until it abuts in the electronic interface; the robot can be detached again very quickly by its fingers without requiring an additional operating step. Drawings The present invention will be described in more detail below with the aid of examples of gearmotor modules and their method of manufacture shown in the accompanying drawings in which: FIG. 1 shows a geared motor module in which is inserted the electronic module, FIG. 2 shows another geared motor module with an open electronic interface, FIG. 3 is a sectional view of an inserted electronic module, FIG. 4 shows another electronic module without a mounted circuit board, FIGS. and 6 show the geometry of the joints according to FIG. 4, FIGS. 7a and 7b show the guide geometry of another electronic module. DESCRIPTION OF EMBODIMENTS OF THE INVENTION FIGS. 1 and 2 show a geared motor module 10 after and before the insertion of the electronic module 34, in particular intended for an ice lifter. The rotor shaft 16 protrudes from the pole housing 14 of an electric motor 12 and enters the housing 18 of the geared motor. The rotor shaft 16 carries a screw 20 engaged with a screw wheel 22 to transmit the force by a drive gear 26 mounted on the shaft 24 to a non-detailed window mechanism. To enter the position of an adjustable part, the rotor shaft 16 comprises in the region of the transmission housing 18, a signal generator 28, for example in the form of an annular magnet cooperating with sensors 30, preferably with Hall sensors installed on a circuit board 32 of the electronic module 34. To engage the electronic module 34, the geared motor 10 comprises an electronic interface 36 made in one piece with the transmission housing 18 by a method of 'injection. The electronic interface 36 comprises spaced apart walls 38 spaced from the rotor shaft 16. The two walls 38 form substantially the housing 40 of the electronic circuit 33 with an opening 42 oriented radially with respect to the rotor shaft 16 and an opening ture 44 oriented axially with respect to this rotor shaft 16; the openings 42 and 44 communicate and constitute practically the common opening for two directions of opening (the radial direction and the axial direction). The two walls 38 which, at first approximation are parallel and are oriented towards the rotor shaft 16, communicate via another connecting wall 39 substantially perpendicular to the walls 38 and to the rotor shaft 16 The housing 18 of the geared motor has a recess 46 in the direction of the rotor shaft 16 to receive the circuit board 32 in the radial direction or tangential to the rotor shaft 16. If the recess 46 is for example a passage open towards the inside of the motor, it is necessary that at the same time as the electronic module 34 is slid into the insertion direction 51, the watertightness of the entire cavity of the motor and geared motor to protect the drive means in a humid atmosphere. For this, the interface 36 of the electronics comprises different sealing surfaces 50 cooperating respectively with seal segments 60 of the electronic module 34. When the electronic module 34 is introduced, electrical contact is made between the contacts 91 of the motor connected to the circuit board and the unrepresented brushes of the electric motor 12. In a plane 52 transverse to the rotor shaft 16, the electronic interface 36 comprises guide rails 54 which receive corresponding guides 56 of the electronic module 34 The guide rails 54 are made here in the form of a folded extension 55 of the lower axial edge of the walls 38. Correspondingly, the electronic module 34 comprises guides 56 in the form of grooves 57 receiving the folded extension 55 in FIGS. the axial direction. When the electronic module 34 is engaged in the insertion direction 51 along the guide rails 54, the module 34 encounters a stop 62 of the electronic interface 36 when the electronic module 34 reaches its final radial position. The electronic module 34 is an injected plastic part having a first surface 66 and a second surface 67 forming the two openings 42, 44 of the electronic interface 36 to constitute the housing 40 of the electronics. The first surface 66 constitutes a radial outer wall 69 (thus oriented with respect to the rotor shaft 16); the second surface 67 closes the electronic module 33 in the axial direction 49. A peripheral connector skirt 64 is provided at an axial distance from the second surface 67; this skirt surrounds the pins 65 of the connector, pins which through the second surface 67 touch the circuit board 32, for example by pressure contact or welds. The guides 56 are formed between the connector skirt 64 and the second surface 67; these guides arrive in the plane 52. The peripheral end faces 68 of the first and second surfaces 66, 67 comprise joint segments 60, in particular made by injection as radial seals with respect to the direction of insertion 51. The seal segments 60 are continuous, without interruption; a joint area 61 acts as an axial seal which, in the direction of the insertion 51, bears against the other housing wall 37 facing the polar housing 14. The seal segments 60 of the electronic module 34 are pressed against the surfaces 50 of the electronic interface 36, relative to the insertion direction 51. The walls 38 are here substantially rectangular in shape so that the sealed internal volume of the electronic housing 40 thus formed is substantially at a cubic volume . The guides 56 and the guide rails 54 are practically perpendicular to the rotor shaft 16. In order to form a non-removable connection of the electronic module 34, the electronic interface 36 comprises attachment elements 76 penetrating into additional hooking elements 74 of the electronic module 34. The hooking elements 76 are made in the form of hooks 78 connected by elastic branches 80 in the plane 52, by a connection by the material to the electronic interface 36 In FIG. 2, the branches 80 are located in the two sidewalls 38 spaced apart substantially parallel thereto. By way of example, the branches 80 are formed in the region of the outer wall 37 of the electronic interface 36, turned towards the pole housing 14. When the electronic module 34 is engaged, the 64 s connector skirt extends in the axial direction 49 and the hooking elements 76 and the complementary hooking elements 74 come between the connector skirt 64 and the second surface 67 in the plane 52 transverse to the rotor shaft 16. The first surface 66 forms the radial outer wall 104 of the electronic housing 40. A recess 105 is formed in this wall; it extends in the insertion direction 51. For the mounting of the electronic module 34, the robot fingers 107 are housed in this recess 105 by pressing against the inner side walls 108 of the recess 105. The inner walls 108 form a plug geometry 106 so that, at mounting, the electronic module 34 is slidably interlocked integrally on the robot fingers 107 until after the complete assembly of the electronic module 34 the fingers can again free. The depression 105 is located axially in the area between the second surface 67 and the connector skirt 64; it is thus outside the electronics 33 closed in a sealed manner, but nevertheless inside the electronic box 40. Thanks to the shape of the engagement geometry 106 as the hollow 105 in the outer radial wall 104, this wall 104 does not have a radial extension 113 facing outwards and which would be necessary to hold the electronic module 34. FIG. 3 is a sectional view of the electronic module 34 in the plane 52 of the fastening elements and the elements of FIG. complementary snaps 76, 74 which are here outside the internal volume of the electronics sealed by the seal segments 60 as shown in Figure 2. Figure 3 shows the electronic module 34 engaged in the electronic interface 36; the cut passes through the base 63 made to have connector pins 65 rotated towards the inside of the housing. The connector pins 65 are fixed in the base 63, in particular they are force-applied or injection-molded. The base 63 has complementary fastening elements 74 on the side facing the fastening elements 76 in the insertion direction 51; these elements 74 are made in the form of hooking nose 75. The extension 70 of the two complementary hooking elements 74, transversely to the insertion direction 51, is greater than the internal distance 72 between the two elements of FIG. fastening 76, relaxed, transversely to the insertion direction 51. When engaging the complementary fastening elements 74 in the engagement direction 51 between the insertion ramps 77 of the fastening elements 76, the fastening elements 76 are opened transversely to the insertion direction 51 by deforming the elastic branches 80 towards the walls 38.
    [0007] When the electronic module 34 is in the fully inserted position, the hooking elements 76 are elastically returned once the complementary hooking elements 74 have passed completely over the insertion ramp 77 between the hooking elements. 76. The electronic module 34 has an abutment surface 82 which bears against the free end of the fastening elements 76 in the direction of insertion 51. Another stop 62 for the direction of insertion 52 is provided for in FIG. end of the guide rails 54 on the electronic interface 36. This allows the electronic module 34 to be positioned exactly with the robot fingers 107 so that the seal segments 60 are optimally applied against the sealing surfaces 50 37, 39, in particular in the axial direction of the sealing zone 61. In the fully inserted state, the spaced walls 38 surround the housing wall 37 and the partition wall. Para 111 surrounds the snap connection 73 in the plane 52 transversely to the rotor shaft 16. The attachment spoilers 75 taken transversely to the direction of insertion 51 are made by way of example asymmetrically with respect to the base 63. Thus, the base 63 (and thus in particular also the connector skirt 64) are not in the central position vis-à-vis the width of the electronic module 34, but are offset. The stop 82 is formed by an extension 85 in the insertion direction 51 which bears directly against the housing wall 37 of the electronic interface 36. In this embodiment, the spaced walls 38 have control orifices 86. which makes it possible to examine transversely to the insertion direction 51, the attachment of the fastening elements put in place without the attachment elements 76 being able to be released through the control orifices 86. Control orifices 86 are made in the region of the guide rails 54 or their extension relative to the pole housing 14 in the plane 52 in the form of a passage whose dimensions correspond substantially to the extension of the guide ramps 77. It can be verified that snap connection 73 is correctly carried out for example by making a depth measurement or by deflecting elastically through control orifices 86 with respect to the elements. The hollow 105 is shown to the left of the partition 111 in which are gripped the fingers 107 of the robot. After insertion into the insertion direction 51, the fingers 107 of the robot are pressed transversely against the inner walls 108 of the recess 105. The base 63 is located between the robot fingers 107 in the direction of the width 115. The fingers robot 107 is used to firmly take the electronic module 34 and position it. The insertion is done via an unrepresented axial extension, transversely to the robot fingers 107; this extension is applied against the thrust surfaces 116 of the outer wall 108 according to an alternative embodiment not shown, the robot fingers 107 can also be pressed against the intermediate base 63 to ensure the holding of the electronic module 34. Figure 4 shows another embodiment of the electronic module 34. In this embodiment, the first and second surfaces 66, 67 form between them an angle 87 of between 92 ° and 115 ° and which is in particular equal to about 95 °. The seal segments 60 have a corresponding pattern on the front face 68 of the two surfaces 66, 67 also making this angle 87. Thus, when the electronic module 34 is introduced into the electronic interface 36, the entire radial pressure force Joint segments 60 occur only when the fully engaged position is achieved, which greatly simplifies the mounting process and secures it. As in Figure 4, the circuit board 32 is not yet mounted, there is a frame 88 which bears against each other of the two surfaces 66, 67. The base 63 with the pins 65 extend into the axial direction 49 from the inner side of the second surface 67 as a passage to the connector skirt 64. It appears that the surface 89 of the bottom of the connector skirt 64 on which are formed the guides 56 form with the - Ce surface 67 a wedge-shaped cavity 90 inside which are, on the one hand the fastening elements 76 and the complementary fastening elements 74 and on the other hand, the hollow 105 (shown in FIG. broken lines). The depression 105 is separated from the snap connection 73 by the partition 111 so that the snap connection 73 is not accessible from the outside. In this embodiment, after insertion into the electronic interface 36, the second surface 67 constitutes another wall of the electronic box 40 and the bottom surface 89 of the connector skirt 64 constitutes the outer axial wall of the electronic box 40 ; the cavity 105 between the second surface 76 and the bottom surface 89, especially outside the internal volume of the electronics 33 sealed by the seal segments 60. In Figure 4, the guide 56 and also the elements of In the direction of insertion 51, the frame 88 has, in the direction of the opening 46 of the housing 18, connectors 91 in the zone of rotation. receiving 97 to achieve the electrical connection of the circuit board 32 by the contacts 95 of the engine and carbon brushes not detailed. To correctly position the electronic module 34 in the electronic interface 36, the frame 88 has a plurality of bearing surfaces 92 which engage the electronic interface 36 after complete insertion. Thus, the electronic module 34 is positioned exactly in both the insertion direction 51, radially with respect to the rotor shaft 16 and also in the axial direction 49 with respect to the housing 18 of the geared motor. Optionally, the bearing surfaces 92 may also have an insertion cone 93, which simplifies the automatic assembly of the electronic module 34 with the aid of the robot fingers 107. FIG. 5 is a top view of the FIG. 4 showing that the seal segments 60 formed on the second surface 67 are, relative to each other, a small angle 94 of between 1 ° and 5 °, and in particular 3 °. Since these seal segments 60 are inserted in the insertion direction 51 between the spaced apart walls 38 which also make a small angle 94 between them, this considerably reduces the insertion force required for mounting and allows faster insertion. the robot fingers 107 in the electronic module 34 and braking suddenly before the limit stop 62, 82. To the right of the figure, appears the abutment surface 92 with an insertion cone 93, these various elements being made on the frame 88. The bearing surface 92 is formed in the receiving zone 95 of the motor contact 91. The receiving pins 96 of the circuit board 32, not shown, are furthermore formed on the frame 88. 105 is shown in broken lines on the left side; in the direction of insertion 51 the depth of the cavity is closed by the partition 111. The base 63 passes through the partition 111 to reach the cavity 105; the base 63 is located in the middle along the width 115 of the electronic module 34 so that the robot fingers 107 can be introduced on both sides of the base 63. FIG. 6 is a left view of FIG. 90 °) showing the seal segments 60 provided on the end faces 68 of the first surface 66. In the axial direction 49 (in the region opposite to that of the connector skirt 64) the sealing zone 61 has a zone bent 59 whose two branches 58 form an angle 98 between 170 ° and 180 ° and preferably equal to about 174 °. This bent zone 59 is applied against the connecting wall 39 of the electronic interface 36 after insertion; this wall is also made bent at the angle 98. At automatic assembly by the robot fingers 107 this ensures the reliability of the sealing effect vis-à-vis the axial direction 49. In this embodiment, the Hollow 105 has inner walls 108 angled in the width direction 115 to center the fingers 107 of the robot as they are inserted. Likewise with respect to the axial direction 49, axial centering surfaces 109 have been formed which axially adjust the robot fingers 107. FIG. 7a shows another embodiment according to the representation of the FIG. 6 (view turned 90 °); in this embodiment, the electronic module 34 is inserted into the electronic interface 36. The spaced apart walls 38 each have a guide rail 54 oriented axially in the direction of the connector skirt 64. a folded extension 55. The folded extensions 55 penetrate into the corresponding guides 56 of the electronic module 34; these guides are made here in the form of grooves 57. To facilitate the insertion of the electronic module 34, the guide rails 54 of the electronic interface 36 include insertion fades 100 in the region of the radial opening 42. The insertion leaves 100 pass on the guides 56 which, as an option, may have corresponding insertion leaves 102. The corresponding insertion leaves 102 are made on the side of the electronic module 34 turned in the insertion direction 51 of the electronic interface 36. Between the end face 68 of the first surface 66 and the sealing surfaces 50 of the two 38, there are the seal segments 60 made here as radial seals oriented transversely to the insertion direction 51. The wedge-shaped cavity 90 has, in this case a partition 111 in the insertion direction 51 so that there is a hollow 105 open in the insertion direction 51 for the mounting robot which can then introduce the electronic module 34 in a fully automatic manner in the radial opening 42 of the electronic interface 36. The cavity 105 also has an axial tapered surface 109 with respect to the axial direction 49 for axial centering of the robot fingers 107 prior to clamping. The conical surfaces 109 are funnel-shaped, i.e. straight, but they can also be curved. To insert the electronic module 34 in the insertion direction 51, the robot bears against defined pushing surfaces 116, made on the outer wall 104. The open recess 105 is traversed by the base 63 through which are guided the connector pins 65 of the electronics 33 to the connector skirt 64. In the sense of view, the robot fingers 107 can penetrate both sides of the base 63 into the recess 105; the robot fingers 107 are pressed, either by spacing against the inner wall 108 of the recess 105 or by coming together against the base 63. FIG. 7b shows an enlarged view of the electronic interface 36 of the embodiment of FIG. 7a. ; the electronic interface 36 is rotated 180 ° in this view. The side of the spaced apart walls 38, not rotated in the axial direction 49, has guide rails 54 which extend substantially only half of the extension of the electronic interface 36 in the insertion direction 51. At the end of the guide rails 54, there are on either side control orifices 86 which, once the insertion of the electronic module 34 is complete, face the hooking elements 76 as shown in FIG. FIG. 3. The detail view correspondingly shows, in FIG. 7A, the insertion fillers 100 made on the folded extension 55 of the walls 38. The folded extension 55 is almost folded twice each time by 90 ° so that it develops parallel to the spaced apart regions 38.
