Definitions
- the invention relates to a TML electronic module (in English Transfer Molded Leadframe or in French bus molded by transfer), in particular for rotary electrical machine, comprising an overmolding for holding pins.
- TML technology is used for the manufacture of electronic modules, for example intended to power an electric motor.
- Patent application US2010140786 A1 presents an electronic module produced using this TML technology.
- components are mounted on tracks transmitting a power or control signal to the components.
- An electrical insulator is overmolded on the tracks and the components.
- the electrical insulator is, for example, a thermosetting resin of the epoxy type.
- Such an electrical insulator allows in particular mechanical maintenance between the traces and the components.
- Certain traces extend outside of the electrical insulation, in particular to allow electrical connections.
- Certain traces are intended, for example, to power an electric machine.
- Other traces, or control pins are intended to transmit a control signal to a control module.
- the control module is for example a control card positioned parallel to the part covered with the electrical insulation of the electronic module and at a distance therefrom. The control pins therefore extend between the overmolded electrical insulation and the control module.
- control pins may be bent. This results in difficulties or even inability to connect the control pins to the control module. For example in the case of control pins passing through the control card in openings made in the control card, it is necessary to have a good positioning of the control pins relative to the control module which is made impossible if the control pins are bent.
- control in order to be able to make a quality weld or solder between the control pins and the control module.
- the length of the control pins, their possible deformation as well as the positioning tolerances between the control module and the part covered with the electrical insulation of the electronic module make precise positioning difficult and therefore risk causing bad welds or bad soldering.
- the present invention aims to eliminate all or part of these drawbacks.
- the invention relates to an electronic module comprising:
- a first housing overmolded on the electronic component and on the two tracks, and a second housing for mechanical support of the two tracks, placed at a distance from the first housing.
- the second holding box allows relative holding between the tracks. Thanks to this holding, the traces, or pins, can have a more precise relative position. Positioning between the pins and a secondary electronic module, such as a control module, is then facilitated. This correct positioning allows in particular the insertion of the pins into the secondary electronic module without risking twisting the pins when they are inserted into the connection holes of the secondary electronic module.
- first and second boxes are only connected to each other by the traces.
- the offset along the tracks between the first case and the second case can make it possible to provide a zone for folding the tracks.
- the second holding box also allows precise positioning of the ends of the traces, or pins, relative to the secondary electronic module. This precise positioning facilitates the electrical connection between the pins and the secondary electronic module. In particular, it allows good quality soldering / soldering between the pins and the secondary electronic module thanks to the soldering / wave soldering technique.
- This soldering / brazing technique requires that the traces exceed a precise length of the module connection holes, here the secondary electronic module, with which an electrical connection must be made.
- the length of protrusion of the traces is for example 1, 2mm +/- 0.4mm.
- the secondary electronic module is for example an electronic card supporting electronic components.
- the electronic card has connection holes in which the traces, or pins, are inserted.
- the second holding box makes it possible to obtain a precise positioning of the ends of the traces relative to the face of the electronic card by which the traces come out of the connection holes.
- the second housing is molded.
- the overmolding technique ensures good positioning of the traces between them and relative to the second housing.
- the portion of the traces which is overmolded by the second housing may comprise a holding element, in particular a protuberance and / or a notch and / or a folding, so as to improve the fixing between the traces and the second overmolded housing.
- the first housing and the second housing are made of the same material.
- the realization of the first housing and the second housing in the same material allows a simplification of the manufacture of the electronic module. Thanks to this characteristic, it is possible to produce the first housing and the second housing during a single molding operation.
- the material of the first housing and the second housing is an epoxy resin.
- the second housing comprises a positioning means with respect to a secondary electronic module, in particular a control module intended to control the electronic module, the electronic module being in particular a control card.
- a positioning means simplifies the manufacture and the shaping of the pins. Indeed without positioning means, it is necessary to shape the end of the pins in particular in the shape of a diamond point. Thanks to the use of the positioning means, this costly shaping operation is no longer necessary.
- the positioning means comprises protuberances formed in the second overmolded housing.
- the protrusions can be used as a positioning means.
- the cost of this solution is particularly low. Indeed, the shapes necessary for positioning are obtained directly during the molding operation of the second housing.
- the positioning means comprises a pin.
- the pawn is formed from the same material as one of the traces.
- the positioning means is attached to the second housing.
- the second housing comprises a surface receiving a seal.
- a seal on the second housing makes it possible, for example, to ensure a seal between two zones located on either side of the second housing along the tracks.
- the seal may, for example, be in contact with a surface of a support housing separating these two zones. Thanks to this seal it is then possible to use a protective gel in one of these zones while preventing the gel from penetrating into the other of these zones.
- a peripheral surface of the second housing is able to follow the shape of a chimney of a support housing on which the secondary electronic module is fixed.
- This characteristic also makes it possible to ensure a seal between two zones situated on either side of the second housing along the tracks.
- the electronic module comprises a second electronic component on which the second housing is molded.
- Component integration increases the compactness of the electronic module.
- the housing of a TML-type electronic module may have a generally flat shape.
- the use of a second box in addition to the first box can reduce the surface of the first box by integrating components in the second box which can be located in a different plane thanks to the possibility of folding traces between the first box and the second box.
- the second housing can allow the use of a component having, for example, a lower temperature withstand than the component on which the first housing is molded.
- a component having, for example, a lower temperature withstand than the component on which the first housing is molded For example in case of overheating of the component overmolded in the first housing, it is useful to have, in the second housing, components intended to monitor the component overmolded in the first housing to control a safety device.

- Such an inverter is for example used to supply electrical energy to a motor-generator linked in rotation to the crankshaft of an internal combustion engine by means of a belt or an electric motor propelling an electric vehicle.
- the inverter comprises at least one electronic module 1 mounted on a heat exchange surface 22 of a heat sink 4.
- the heat exchange between the heat exchange surface 22 of the heat sink 4 and the electronic module 1 is carried out for example by contact, direct or through a thermally conductive paste, between the heat exchange surface 22 of the dissipator 4 and the electronic module 1.
- the inverter also includes a support box 3 on which is fixed a secondary electronic module such as a control module 2.
- a control module 2 is a control card.
- the support box 3 is mounted on the heat sink 4.
- FIG. 2 represents a first embodiment of the electronic module 1 according to the invention.
- Such an electronic module 1 comprises components mounted on power traces 5 transmitting a power signal from the or to the components and control traces 6 transmitting a control signal from the or to the components.
- An electrical insulator is overmolded on the tracks and the components. This electrical insulator forms a first housing 7.
- the electrical insulator is for example a thermosetting resin of the epoxy type.
- Such an electrical insulator allows in particular mechanical maintenance between the traces and the components.
- Certain traces extend outside of the electrical insulation, in particular to allow electrical connections.
- the traces of power 5 are for example intended to supply an electric machine or receive electrical energy from an electrical energy source such as a battery.
- the control traces 6, or control pins, are intended for the transmission of a control signal between the control module 2 and the components.
- the components are for example controllable electronic switches 19.
- the controllable electronic switches are preferably transistors, for example field effect transistors with a metal-oxide-semiconductor structure (from the English "Metal Oxide Semiconductor Field Effect Transistor” or MOSFET) having a grid electrically connected to one of the control traces 6, and a drain and a source electrically connected to two of the power traces 5.
- MOSFET Metal Oxide Semiconductor Field Effect Transistor
- the electronic module 1 comprises a second housing 8.
- the second housing 8 is molded onto the control traces 6.
- the second housing 8 is placed at a distance from the first housing 7.
- the second housing allows maintenance of the control traces 6.
- the second housing 8 is made of the same material as the first housing 7.
- the second housing 8 is therefore for example made of a thermosetting resin of the epoxy type.
- FIG. 3 represents the electronic module 1 in the environment of the inverter.
- the support housing 3 comprises a wall 24.
- the wall 24 comprises a first face 25 and a second face 26 opposite the first face 25.
- the first housing 7 is located on the side of the first face 25.
- the control module 2 is located on the side of the second face 26.
- First holes 9 are formed in the wall 24 to allow the passage of the control traces 6.
- Second holes 10 are formed in the control module 2 to allow the passage of the control traces 6 and allow an electrical connection between the control traces 6 and the control module 2.
- the control traces 6 may include an end 23 in the shape of a diamond tip or frustoconical shape. Such an end shape facilitates the insertion of the control traces 6 in the first holes 9 and the second holes 10.
- the first holes 9 may for example have a frustoconical shape, the large base of which is situated at the level of the first face 25. Such a frustoconical shape makes it possible to facilitate the insertion of control traces 6 in the first holes 9.
- the face of the second housing 8 through which the control traces 6 emerge is a bearing face 27.
- the length H is the distance between the end 23 of the control traces 6 and a face of the control module through which the control traces 6 exit.
- This improvement in the precision of the length H allows an improvement in the electrical connection between the control traces 6 and the control module 2.
- the electrical connection between the control traces 6 and the control module 2 is carried out by a solder / wave solder. Thanks to the improvement of the control of the length H, a preferred length H of 1, 2mm +/- 0.4mm can be obtained.
- This improvement in the length H is obtained thanks to a reduction in the length of the dimension chain between the end 23 of the control trace 6 and the control module 2.
- the production of the second housing 8 by overmolding allows a good control of the position of the end 23 of the control trace 6 relative to the second box 8.
- the second box 8 being supported on the support box 3 which carries the control module 2, the dimension chain is very short .
- the control traces 6 comprise in an area located between the first housing 7 and the second housing 8 an adaptation zone 28.
- This adaptation zone makes it possible to increase the deformation capacity of the control trace and therefore to avoid significant constraints in the control traces 6 as well as at the interface between the control traces 6 and the first and second housing 7 and 8.
- FIG. 4 represents a second embodiment of the electronic module 100 according to the invention in the environment of the inverter. This second embodiment is similar to the first embodiment.
- control module 2 of the inverter being here protected by a protective gel 1 1 received in the support box 3 and the support box 3 comprising the first holes 9 for passage of the control traces 6, it may be necessary to d '' ensure a seal between the control traces 6 and the support box 3.
- the seal is produced by a seal 12 carried by an external peripheral surface of the second housing 8.
- the support housing comprises a chimney 13 inside which the control traces 6 pass to join the holes 9 in the wall 24 of the support housing.
- An external surface of the seal 12 is in contact with the internal surface of the chimney 13.
- the seal 12 provides a first seal between the chimney 13 of the support housing 3 and the second housing 8.
- the housing 8 being overmolded on the traces of control 6, the protective gel 1 1 cannot flow between the second housing 8 and the traces 6. A second seal between the control traces 6 and the housing 8 is therefore ensured.
- the first seal and the second seal therefore make it possible to ensure the seal between the support box 3 and the control traces 6.
- FIG. 5 represents a third embodiment of the electronic module 101 according to the invention in the environment of the inverter. This third embodiment is a variant of the second embodiment.
- the internal surface of the chimney 13 has a draft d.
- the second housing 8 has an external surface which matches the shape of the draft d of the chimney 13. The seal between the support housing 3 and the second housing 8 is ensured by this complementarity of shapes between the draft d of the chimney and the outer surface of the second housing 8.
- control of the length H defined above is not ensured by contact between the bearing face 27 and the first face 25 of the wall 24 of the support housing 3 but by contact between the surface external of the second housing 8 and the clearance of the chimney 13.
- FIG. 6 represents a fourth embodiment of the electronic module 102 according to the invention in the environment of the inverter here limited to the control module 2 to facilitate reading of the figure.

- the positioning means can also facilitate the insertion of the control traces 6 into the support box 3 (not shown).
- the positioning means comprises two pins 14 and 14 ’.
- the two pins 14 and 14 ’ have a longer end than the control traces 6.
- the two pins 14 and 14 ′ may, for example, have one end in the shape of a diamond point. It is then possible not to make a diamond point shape on the control traces 6. This can allow a reduction in the cost of the electronic module 102.
