Figures 1 and 2 show perspective views of an example of electrical equipment 1 which comprises an electrical connection bar according to the invention. The electrical equipment includes a set 100 which houses the components of the electrical equipment 1. The electrical equipment 1 comprises in particular an inverter intended to power an electrical machine such as a rotating electrical machine, for example a machine intended to drive the electrical equipment. wheels of a vehicle, from a first electrical network of the vehicle. The electrical equipment includes a DC / DC converter for converting a voltage between the first DC grid and a second DC electrical network of the vehicle. The inverter and the DC / DC converter can both be integrated in the electrical equipment 1, which makes it possible to gain in integration density in the vehicle. For example, the first power grid is a high voltage network and the second power grid is a low voltage network. Typically, a low voltage network delivers a voltage of less than 60V, in particular about 18 or 12V; a high voltage network delivers a voltage greater than 60V, especially greater than 100, 200 or 400V.
Figure 7 shows the integration of an electrical connection bar 400 according to the invention in a housing 110 of the electrical equipment 1. Some components are not shown to facilitate understanding.
The connection bar 400 makes an electrical connection with a first component 300. In particular, the electrical connection bar 400 connects the first component 300 with an electrical connector 382. The electrical connector 382 passes through an opening of the housing 110 to allow an exchange of electrical power. electrical energy between the first component 300 and the outside of the electrical equipment 1, in particular with the phases of the electrical machine controlled by the inverter. Figures 16 to 18 show perspective views of the connecting bar 400.
The electrical connection bar comprises three electrically conductive parts 410. In particular, each electrically conductive part 410 makes it possible to electrically connect a phase of the electrical machine controlled by the inverter with the first component 300. The connection bar 400 could comprise a different number of pieces 410, in particular a number depending on the number of phases of the the electrical machine controlled by the first component 300. Each conductive part 410 is in particular an integral part. The electrically conductive parts 410 are, for example, made of copper.
A coating 420 covers the conductive parts 410 of electrically insulating material. In particular, the insulating material is a plastic material overmolded on the conductive parts 410. The coating 420 covers the conductive parts 410 in a plane β in which extends a flat portion 413 of the conductive part 410. A first end 411 of the workpiece The first end 411 comes into contact with a terminal 382e of the electrical connector 382. A mechanical contact is for example obtained by a screw, by welding or by any other means.
In particular, the first end 411 is connected to the flat portion 413 by an intermediate portion 412. The allows to cross a distance between the flat portion 413 and the first end 411. In particular the first end 411 is positioned to correspond with a terminal 382e of the electrical connector 382.
The intermediate portion 412 may extend in a direction transverse to the plane β or in a direction parallel to the plane β to allow contact with the terminal 382e of the electrical connector 382.
The first end 411, the intermediate portion 412 and the flat portion 413 are in particular in one piece. They can be formed from a single blade, including a metal blade.
The flat portion 413 includes an opening 413a. A cylinder 414 of electrically conductive material extends from the opening 413a from a first face of the conductive part 410 in a direction transverse to the main plane β. The cylinder 414 is for example copper. In particular, the cylinder 414 is attached to the flat portion 413. The cylinder 414 is in particular secured to the flat portion 413 by a laser weld or with an adhesive for example. The cylinder 414 and the flat portion 413 could be secured in another way, provided that there is an operational electrical contact between the connection bar 400 and the first component 300. Alternatively, the cylinder 414 and the flat portion 413 could be obtained together by conforming the same material.
In particular, the proximal end 414b of the cylinder 414 corresponds with the opening 413a of the flat part 413. In particular, the inner wall of the cylinder 414 at the proximal end comes into correspondence with the edges of the opening 413a. 414 of the flat portion 413. The cylinder 414 is hollow and forms in particular a barrel in which can be introduced a rod 500 through the opening 413a of the flat portion 413.
When mounted in the electrical equipment 1, the cylinder 414 receives the rod 500 which comes to bear the distal end 414a of the cylinder 414 against an electrical terminal 300e of the first component 300. The distal end 414a of the cylinder 414 thus forms an electrical connection terminal of the connection bar 400. The cylinder 414a deports the electrical terminal of the connection bar 400 from the main plane β to bring it to a plane distant from the main plane β. Thus, the main plane β of the connection bar may be at a different level from the plane in which the electrical terminal 300e of the first component 300 is located, which improves the integration of the components in the equipment box 110. 1. Pressing the distal end 414a of the cylinder 414 with the electrical terminal 300e of the first component 300, the rod 500 ensures a good electrical contact between the distal end 414a of the cylinder 414 and the electrical terminal 300e of the first component 300.
In particular, the coating 420 leaves bare a portion of the flat portion 413 at the immediate periphery of the opening 413a of the flat portion 413. A second face the flat portion 413 which is opposite to the first face is therefore devoid of electrically insulation around the opening 413a. Thus, a head 500a of the rod 500 can come to exert a force directly on the surface of the conductive part 410 and not on the coating 420, which improves the resistance in time of the bearing of the cylinder 414 on the 300th terminal of the first component 300.
The rod 500 may be made of electrically conductive material, such as a metal such as steel. By coming into direct contact with the surface of the conductive part 410, the head 500a can allow circulation of a current through the rod 500 which contributes to the exchange of current between the connection bar 400 and the first one. component 300.
To carry out the bearing of the cylinder 414 on the electrical terminal 300e of the first component 300, the rod 500 may comprise a thread which corresponds with a corresponding thread in the inner wall of the cylinder 414 and with a corresponding thread in a hole of the terminal 300e of the first component 300. A washer can be inserted between the head 500a of the rod 500. However, the support could be obtained otherwise; for example with a pressat technique. In addition, by coming into engagement with the electrical terminal 300e of the first component 300, and in particular with the inner wall of the cylinder 414, the rod 500 contributes to the mechanical maintenance of the connection bar in the electrical equipment.
The coating 420 may comprise protuberances 421 which contribute to the mechanical maintenance of the electrical connection bar 400, in particular in the housing 110 of the electrical equipment 1. The protrusion 421 extends transversely from the main plane β of the same side that the cylinder 414. In particular the protrusion 421 forms a tab whose distal end 421a bears against a support S. In particular, the support S is a portion of material of the housing 110 of the electrical equipment 1. L distal end 421a thus forms a surface that bears on support S to contribute to the mechanical retention of connection bar 400 in housing 110. In particular, protrusion 421 extends from the part of coating 420 which is in the main plane, away from the cylinder 414. This improves the stability of the connection bar 400 in the electrical equipment. The distal end 421a of the protrusion 421 may comprise a pin 421c which comes into a hole of the support S for indexing in position of the connection bar 400 when it is mounted in the housing 110. In particular, the connection bar 400 is introduced in a direction in the housing 110 by an opening defined by side walls 116 of the housing 110. In particular, the pin 421c cooperates with the hole of the support S to block the connection bar 400 in directions transverse to the introduction direction, but not in the direction of introduction, so as to ensure that a bearing is obtained between the distal end 414a of the cylinder 414 and the terminal 300e of the first component 300.
In particular, the cylinder 414 extends perpendicularly from the main plane β. The direction of the cylinder 414 corresponds in particular to the insertion direction of the electrical connection bar 400 to be positioned in the electrical equipment 1.
The first component 300 is in particular an electronic power module 300 forming part of the inverter. In particular, the electronic power module 300 includes components for powering the electric machine. The electronic module designates a set of components, in particular electronic switches, such as semiconductor transistors, which are mounted in a case specific to the module 300 and accessible electrically from outside the case specific to the module 300 by the electrical terminals 300e of the module 300. The switches are in particular arranged in electrical circuit to allow a controlled passage of electrical energy between a power source, including the first electrical network of the vehicle, and an external component, including the electrical machine controlled by the inverter . This electronic power module 300 can be supported by a first wall 111 of the box 110, which forms in particular a bottom of the box 110
An electronic control unit 370 and a support 375 of the electronic control unit 370 are for example housed in the same housing 110, as illustrated in FIGS. 5 and 15. The support 375 of the electronic control unit 370 is a wall , in particular a plate, which is suspended in the housing 117 defined by the housing 110. For example, the support is attached to the housing 110 and held in place by bearing against portions of material of the first housing 110, including excrescences 157 from the surface of the housing 110. The support 375 is in particular held in place by bearing at its periphery. The support 375 is for example made of metal to improve the heat dissipation of the electronic control unit 370. The electronic control unit 370 is in particular an electronic card 370 on which components 371 are mounted. The electronic control unit 370 is supported by the support 375 via a face in contact with the support 375. In particular, the electronic control unit 370 controls the components of the inverter and / or the converter DC / DC, in particular the switches of the electronic power module 300. For this purpose, the electronic unit 370 can exchange a data signal with the outside of the electrical equipment, for example with a controller of the vehicle.
In particular, the power module 300, the support 375 of the electronic control unit 370 and the electronic control unit 370 are superimposed on each other in the first housing 117 defined by the first housing 110. The support 375 of the electronic control unit is located between the power module 300 and the electronic control unit 370.
When the connecting bar 400 is mounted in the electrical equipment 1, the cylinder 414 passes through the electronic control unit 370 through an opening 370a and passes through the support 375 of the electronic control unit 370 through an opening 375a for contact the electrical terminal 300e of the power electronic module 300. This arrangement saves space in the housing 117 and improves the integration of the components in the housing 117 defined by the housing 110.
In addition, the electronic control unit 370 may comprise current sensors 372 for measuring the currents flowing through the connection bar 400. The current sensors 372 are in particular mounted on the surface of the electronic card forming the electronic control unit. 370. In particular, the electronic control unit 370 comprises a respective current sensor 372 for two of the conductive parts 410 and not for the third conductive part 410. The current flowing through the third conductive part 410 can be deduced from the measured currents on the other two conductive parts. Each current sensor 372 has an opening 372a traversed by the cylinder 414. In particular, the current sensor 372 measures the current from a magnetic field induced by the current flow. The current sensors 372 are, for example, hall effect sensors. Each current sensor 372 may comprise pins 372b which are received in the electronic card forming the electronic control unit 370 for conveying the value of the measured current.
The housing 110, hereinafter referred to as the first housing 110, can be associated with a second housing 120 to form a housing assembly 100 of the electrical equipment 1.
In addition to the electronic power module 300, the electronic control unit 370 and the support 375 of the electronic control unit, the first housing 110 can receive other first components, illustrated for example in FIGS. 3 and 5 to 7. The second housing 120 receives one or two second electrical components, illustrated for example in Figures 4 and 5.
Examples of first 110 and second 120 housing are illustrated in FIGS. 8 to 14. The first housing 110 may comprise a first wall 111 which bears with a second wall 121 of the second housing 120 to form a cooling circuit 200 of the electrical equipment 1. For this purpose, the first wall 111 may comprise a groove 112 which faces a groove 122 of the second wall 120 to form the cooling circuit 200. The cooling circuit 200 receives a fluid intended for cooling electrical equipment 1.
In particular, the first groove 112 and the second groove 122 come face to face to form a channel 210 of the cooling circuit in which the cooling fluid will flow. Thus, the diameter of the cooling channel is distributed between the two walls.
In particular, the first wall 111 and the second wall 121 come against each other at respective substantially planar surfaces 113, 123, so-called bearing surfaces. The bearing surface 113 of the first wall 111 comprises the edges of the first groove 112; and the bearing surface 123 of the second wall 121 comprises the edges of the second groove 122. By edge of the first 112 or the second groove 122 is meant the boundary between the groove 112, 122 and the surface from which the 112,122 throat is digging. The surface from which the first groove 112 is hollow corresponds in particular to the bearing surface 113 of the first wall 111; and the surface from which the second groove 122 is hollow corresponds in particular to the bearing surface 123 of the second wall 121. In particular, the edges of the first 112 or second 122 grooves are integrally included in their bearing surface 113, 123 respective.
By providing flat bearing surfaces between the first 111 and the second wall 121, it facilitates the implementation of the sealing of the cooling circuit 200. Indeed, the portions of the first wall 111 and the second wall 121 which come against each other to form the cooling circuit 200 are preferably machined to remove surface irregularities that could create coolant leakage gaps out of the cooling circuit 200. Providing contact surfaces 113, 123 planes facilitates the machining of these bearing surfaces 113, 123.
The first wall 111 may comprise at least one through hole 114 and the second wall 121 may comprise at least one through hole 124 whose edges come into contact with one another to form a passage between the face of the first wall 111 which is opposed to the face carrying the first groove 112 and the face of the second wall 121 which is opposite the face bearing the second groove 122. In particular, these through holes 114, 124 form a passage between the first housing 117 defined by the first housing 110 and a second housing 127 defined by the second housing 120. These through holes 114, 124, are formed especially outside the areas 111a, 121a of the first 111 and second 121 walls which form the cooling circuit 200 .
A seal may be positioned between the first wall 111 and the second wall 121. An example of a seal 130 is illustrated in FIG. 12. In particular, the seal 130 provides a seal around the zones 111a, 121a. first 111 and second 121 walls which form the cooling circuit 200. For this purpose, the seal 130 comes in particular between the bearing surfaces 113, 123 of the first wall 111 and the second wall 121. sealing member 130 may be devoid of material in a portion which is in the cooling circuit 200 when formed except for strips of material 134, 135, 136. These strips of material 134, 135, 136 improve the rigidity of the seal 130 so as to facilitate the handling and placement of the seal 130. These strips of material 134, 135, 136 may have widths just sufficient to obtain a rigidity and define openings 131, 132, 133. The seal 130 seals along a closed line around the cooling circuit 200, especially around the areas 111a, 121a of the walls 111, 121 which form the circuit The seal 130 may also seal around the passageways formed in the first wall 111 and the second wall 121. The seal 130 then includes holes 137 whose edges seal around it. said passages. The seal 130 may also include holes 139 which allow the passage of respective fasteners for fixing the first wall 111 on the second wall 121.
The cooling circuit 200 may comprise an input port 201 and an output port 202 through which the cooling fluid enters and leaves the cooling circuit 200. The input port 201 and the output port 202 are included in the second case 120, in particular in a side wall 126 of the second housing 120 described below. In particular, the input / output ports 201, 202 are tubular openings in the side wall 116. These input / output ports 201, 202 are extended by tubes 203, 204 which communicate with the second groove 122 of the second wall 121. to route or extract the cooling fluid. Nozzles 205, 206 may be inserted into the input / output ports 201, 202 to adapt them to a cooling fluid supply circuit.
Each housing 110, 120 may include respective side walls 116, 126 extending transversely from the periphery of the first or second wall 121 to define a respective first housing 117 and second housing 127. In particular, when the first 110 and second 120 housings are mounted on each other so as to form the cooling circuit 200, the side walls 116 of the first housing 110 extend in a direction opposite to the second housing 120 and the side walls 126 of the second housing 120 extend in a direction opposite to the first housing 110. Each housing 117, 127 can be closed by a respective cover 118, 128 which comes against the distal ends of said side walls 116 126. Thus, the first wall 111 forms a bottom of the first housing 110 and the second wall 121 forms a bottom of the second housing 120.
In particular, the first housing 110 and the second housing 120 are fixed to each other by fasteners which hold the first wall 111 in abutment against the second wall 121. These fixing members are for example screws introducing into corresponding holes T1, T2 in the first wall 111 and the second wall 121. The fasteners may also be clips, for example carried by the side walls 116, 126 of the first housing 110 and the second housing 120.
The first housing 117 defined by the first housing 110 may comprise an insulated metal substrate (SMI) electronic card 310 being part of the DC / DC converter. The SMI card includes components for the voltage conversion between the first and the second electrical network of the vehicle. The SMI card 310 may be supported by the first wall 111 of the first housing 110, with one of its faces coming into contact with the first wall 111. The SMI card comprises, for example, electronic switches, such as semiconductor transistors, or the like.

These second components 320, 330, 340, 350 may be supported by the second wall 121 with one of their faces coming into contact with the second wall 121.
The first wall 111 may comprise a through opening 115 whose edges correspond to an opening 125 of the second wall 120. A protrusion 156 extends from the edges of the opening 125 on the face of the wall 121 which is opposite. at the face of the wall 121 which carries the second groove 122. The protrusion forms a cavity 151 which receives a capacitive block 315, visible in FIG. 7. The capacitive block 315 comprises several capacitors 316. It is connected to the inverter, in particular to the power electronic module 300, and to the DC / DC converter, in particular to the SMI card 310. In particular, the capacitive block 315 is in the electrical connection between the first electrical network of the vehicle and the electronic power module 300 and the SMI 310 card; and constitutes a power reserve as close as possible to the power electronic module 300 and the SMI card 310, in particular for cutting by their switches. For this purpose, the capacitive block 315 is connected to the power module 300 and the SMI card by an electrical connection bar (not shown). The through opening 115 of the first wall 111 is outside the zone 111a of the first wall 111 which is intended to form the cooling circuit 200. The opening 125 of the second wall 121 is outside the the zone 121a of the second wall 121 which is intended to form the cooling circuit 200. The seal comprises a hole 138 to allow the passage of the capacitive block 315.
The components housed in the first housing 117 may be electrically connected with the second components 320, 330, 340, 350 through the passages defined by the through holes 114, 124 formed in the first 111 and the second wall 121. 5 illustrates an example of an electrical connection between an electrical connector 311 of the SMI card 310 and a terminal of the magnetic component 340 via an electrical connector 360.
In particular, the electronic switches of the inverter and the DC / DC converter of the electrical equipment 1, in particular the electronic power module 300 and the SMI card 310, are housed in one of the two housings 110, 120 whereas the filtering and rectifying components 320, 330, 340, 350 of the electrical equipment 1 are housed in the other of the two housings. This makes it possible to share the filtering components between the inverter and the DC / DC converter. Furthermore, by housing the switches, in particular the electronic power module 300 and the SMI card 310, in the same housing, it is easier to control them with a single electronic control unit 370. Such an electronic control unit 370 is for example housed in the same housing as the switches, as shown in Figure 5.
