Description

Title of the invention: Conductive assembly comprising a set of busbars and a fixing device FIELD OF INVENTION

[0001] The present invention relates to a mechatronic integration, within electrical equipment, of a conductive assembly comprising plate electrical conductors, forming a busbar adapted for delivering electrical power. The electrical assembly also includes a device for fixing the busbar within the electrical equipment.

[0002] The invention also relates to electrical equipment fitted with such conductive assemblies. EARLIER ART

[0003] As is known, an electric or hybrid motor vehicle has an electric drive system comprising an electric motor and other electrical equipment, such as power converters, which must be powered either by a high-voltage or, conversely, a low-voltage supply. In this context, power converters are configured to convert an input voltage into an output voltage. For example, an inverter converts a direct current (DC) voltage from a high-voltage power supply battery into alternating current (AC) electrical power to power the electric motor and drive the vehicle. As another example, an on-board charger (OBC) converts an alternating current voltage from an external power grid into a direct current voltage to charge the high-voltage power supply battery.

[0004] Generally, such power converters have a plurality of electrical components, such as electrical plate conductors forming a busbar, which can cause electromagnetic interference (EMI) that may disrupt the proper operation of the power converter, particularly in a high-power environment. Therefore, electromagnetic (EM) requirements are applied to ensure that the power converter is able to operate in its EM environment and to protect other nearby electrical equipment from potential EM emissions from the power converter.

[0005] In particular, certain electrical components (magnetic cores, capacitive elements arranged in a capacitive module, resistive elements, DC coupling capacitor), adapted to filter EM emissions, are connected to the busbar. The electrical components may be subject to vibrations due in part to EM interference. Therefore, a mechatronic integration of the electrical components must be able to withstand mechanical vibrations while complying with EM requirements.

[0006] It is also necessary to have a simple and modular fixing solution for the electrical assembly which is dependent on the arrangement of the busbar in the equipment and the shape of this equipment.

[0007] In this context, the main objective of the present invention is to provide a conductor assembly comprising a busbar and a fastening device featuring improved mechatronic integration. The present invention also proposes a corresponding assembly method that simplifies the manufacturing process. Summary of the invention

[0008] The present invention relates to a conductive assembly of electrical equipment comprising a housing, the conductive assembly comprising: - a set of busbars, - at least one fixing device on the housing of the busbars, the fixing device comprising a support adapted to be fixed on the housing and a cover, the fixing device having a set of slots, each slot being respectively traversed by one of the busbars,

[0009] The conductor assembly is remarkable in that at least one of the support and the cover includes at least one ramp inclined with respect to an insertion direction so that when the support and the cover slide over each other via the ramp inclined along the insertion direction, the volume of the slots is reduced and the fixing device clamps the busbar set.

[0010] This assembly reduces manufacturing costs because the fastener is simple to manufacture. Adhesive is also not required for such a fastener, thus eliminating a manufacturing operation on the production line.

[0011] This assembly also eliminates the problems of plastic cracking encountered with overmolded fastening devices upstream of the busbar insertion into the electrical equipment. The absence of overmolding and the pinching of the busbars provide an assembly tolerance that allows the busbars to expand without risk of breaking the fastening device.

[0012] This assembly, less bulky than an overmolding assembly, makes it possible to increase the possible cooling areas of the busbar set.

[0013] According to one aspect of the invention, the inclined ramp has an angle with respect to the insertion direction of between 80 degrees and 10 degrees, preferably between 60 degrees and 30 degrees, for example 45 degrees.

[0018] According to one aspect of the invention, each of the support and the cover has an inclined ramp, the inclined ramps sliding over each other.

[0019] The interaction between the inclined ramp and the inclined ramp results in a flat contact surface between the support and the cover. This flat surface facilitates the insertion of the support into the cover and allows for uniform clamping of the busbar assembly.

[0020] Alternatively, only one of the support and the cover has an inclined ramp, the other of the support and the cover has any shape which allows for linear contact, for example a rounded shape.

[0021] According to one aspect of the invention, the support comprises a base from which extend, in the direction of insertion, at least one central wall and at least two lateral walls on either side of the central wall. The two lateral walls and the central wall may define the slots. The central wall may have a free end. Each of the lateral walls may have a free end.

[0035] According to one aspect of the invention, the base comprises: - at least one guide pin capable of fitting into a guide hole in the housing, or, - at least one guide hole suitable for receiving a guide pin for the housing.

[0036] According to one aspect of the invention, the base comprises a set of indexing openings for the busbar. Each indexing opening is traversed by one of the busbars before the busbar is clamped by the fastening device.

[0037] According to one aspect of the invention, each indexing opening is located in line with the slots in the insertion direction. The slots are open in the insertion direction and in the direction opposite to the insertion direction.

[0038] According to one aspect of the invention, each insertion opening has an axis parallel to the insertion direction.

[0039] According to one aspect of the invention, each bus bar has a protrusion that extends into one of the indexing openings. Each protrusion allows, during assembly of the support with the bus bars, the support to be held in position before being fixed to the housing.

[0040] According to one aspect of the invention, the fastening device includes a means for clipping the support onto the cover or the cover onto the support to link them together while allowing relative movement in the direction of insertion.

[0041] The clipping means allows the support and the cover to be held together before their assembly prior to their attachment to the housing.

[0042] According to one aspect of the invention, the clipping means consists of an elastic tab attached to the lid that passes through a clipping opening provided in the support, particularly in the base of the support. The elastic tab can move independently with the lid. Once the elastic tab is clipped, the lid is attached to the support.

[0043] According to one aspect of the invention, the elastic tab may have a cross-section complementary, for example polygonal or square, to the shape of the clip opening.

[0048] According to one aspect of the invention, each omnibus bar of the omnibus bar set rests on the bottom of the cover when the support pinches said omnibus bars.

[0049] According to one aspect of the invention, the cover includes external bosses.

[0050] The external bosses allow the forces of the cover to be distributed on the housing.

[0051] The invention also relates to electrical equipment comprising the conductor assembly as described above, the housing and a power module.

[0053] According to one aspect of the invention, the power module comprises at least one electronic board.

[0054] According to one aspect of the invention, the housing includes a base substantially transverse to the insertion direction which immobilizes the cover in said insertion direction so that, when the support slides on the cover via the ramp inclined along the insertion direction, the volume of the slots is reduced and the fixing device, in particular the support, pinches the busbar set.

Alternatively, the electrical equipment may be an on-board charger or a DC / DC converter for the electric vehicle or hybrid electric vehicle.

[0057] The invention also relates to a method for assembling the busbar of the conductor assembly in electrical equipment. The method comprises the following steps: - Installation of the support on the busbar assembly, - Securing the lid to the support to link them together while allowing a relative movement in the direction of insertion, - Movement of the support, the busbar assembly and the cover towards the housing according to the insertion direction, - Attaching the bracket to the case.

[0058] In the insertion direction, the cover makes contact with the housing at the base. The cover is then stationary relative to the housing, while the support is mobile relative to both the cover and the housing. The support slides along the cover via the ramp inclined in the insertion direction. The volume of the slots decreases until the support clamps the busbar. When the busbars are clamped, the mounting slots in the support are positioned to receive the fasteners that secure the support to the housing. The busbar is then fixed to the support and thus to the housing.

The electric drive comprises an electric motor and electrical equipment such as power converters, for example an inverter configured to drive the electric motor by means of an alternating voltage generated by the inverter.

[0073] Figure 1 illustrates an example of electrical equipment 100 according to an embodiment of a first aspect of the present invention. According to the present embodiment, the electrical equipment 100 is an inverter configured to convert a direct current voltage from a high-voltage power supply battery into an alternating current voltage to drive the electric motor. The alternating current voltage can be a multiphase alternating current voltage, in particular a three-phase voltage. Alternatively, the electrical equipment 100 can be, for example, an on-board charger or a DC / DC converter from an electric or hybrid motor vehicle.

[0074] The electrical equipment 100 includes, in particular, a conductor assembly 1, a housing 120, and a power module. The conductor assembly 1 includes a busbar 10 and a mounting device 11 for the busbar 10 housing 120.

[0075] In the particular case of the inverter, the busbar 10 provides the electrical connection between the supply battery, in particular high voltage, and the electric motor providing propulsion for the vehicle.

[0076] The housing 120 is configured to accommodate the conductor assembly 1, the power module, and other electronic components, not shown in [Fig.1].

[0077] In the example considered, the power module comprises one or more electronic boards 110 fixed to the housing 120 and electrically connected to the busbar 10. The electronic components can be electrically connected to the busbar 10.

[0078] In the example considered, the electronic boards 110 are preferably a printed circuit board (PCB). Only one is shown in [Fig.2].

[0079] Capacitive and resistive elements can be mounted on the electronic board 110, which filter potential electromagnetic emissions. The capacitive elements can, for example, include capacitors X and / or capacitors Y.

[0080] In the example considered, the power module also includes switching elements arranged in power modules. The switching elements can be mounted on one of the electronic boards 110.

[0081] In the example considered, the housing 120 comprises a top cover, a bottom plate, side walls, and a chamber 130 defined by the bottom plate and the side walls. The chamber is used to house the electronic board and the conductor assembly 1.

[0082] In the example considered, the busbar 10 passes through at least one magnetic core device 3, here two. In other words, at least one magnetic core device 3 surrounds at least partially the busbar 10. The magnetic cores 3 are housed in chamber 130.

[0083] Other elements of the electrical equipment 100, such as an insulating card and a heat sink, can also be housed in the chamber 130.

[0084] In the example considered, the other electronic components may include a DC coupling capacitor.

[0085] In the example considered, the busbar 10 consists of two busbars. The busbar 10 comprises two electrical conductors on plates 2, one for B+ and one for B-, first connection elements 4, second connection elements 5, and third connection elements 6. The first connection elements 4 are configured to electrically connect each of the two busbars 10 to the battery. The second connection elements 5 are configured to electrically connect each of the two busbars 10 to one of the electronic boards. The third connection elements 6 are configured to electrically connect each of the two busbars 10 to the switching elements.

[0086] Fig. 2 is a view of the conductor assembly 1 without the housing 120 of Fig. 1 or the electronic components that may equip the electrical equipment.

[0087] Figures 3 and 4 represent the conductor assembly 1 in cross-sectional view and perspective view. In particular, they illustrate the interaction between the busbar 1 and the fastening device 11, and the interaction between the fastening device 11 and the housing 120. The [Fig.5] represents the fixing device 11 alone.

[0088] In the example considered, the mounting device 11 on the housing 120 of the busbar 10 comprises a support 20 fixed to the housing 120 and a cover 21. The mounting device has a set of slots 22, here two. Each slot 22 is respectively traversed by one of the busbars 10.

[0089] In the example considered, according to one aspect of the invention, the set of slots 22 is provided in the support 20.

[0090] In the example considered, the support 20 and the cover 21 each comprise two ramps 23 inclined with respect to an insertion direction X such that when the support 20 and the cover 21 slide over each other via the inclined ramps 23 along the insertion direction X, the volume of the slots 22 is reduced and the fixing device 11, here the support 20, pinches the busbar set 10.

[0091] In the example considered, the housing 120 includes a base 25 substantially transverse to the insertion direction X which immobilizes the cover 21 in said insertion direction X so that when the support 20 slides on the cover 21 fixed in the insertion direction X.

[0092] This assembly reduces manufacturing costs because the fastener is simple to manufacture. Adhesive is also not required for such a fastener, thus eliminating a manufacturing operation on the production line.

[0093] This assembly also eliminates the problems of plastic cracking encountered with overmolded fastening devices upstream of the busbar insertion into the electrical equipment. The absence of overmolding and the pinching of the busbars provide an assembly tolerance that allows the busbars to expand without risk of breaking the fastening device.

[0094] This assembly, less bulky than an overmolding assembly, makes it possible to increase the possible cooling areas of the busbar set.

[0095] In an example not shown, each of the support 20 and the cover 21 has a single inclined ramp 23.

[0096] In an example not shown, only one of the support 20 and the cover 21 has an inclined ramp 23, the other of the support 20 and the cover 21 has an arbitrary shape which allows for the implementation of a linear contact, for example a rounded shape.

[0097] In the example considered, the ramps 23 are straight and they have an angle with respect to the insertion direction of between 80 degrees and 10 degrees, preferably between 60 degrees and 30 degrees, for example 45 degrees.

[0098] In an example not shown, the inclined ramps may be concave, or convex.

[0099] In the example considered, the support 20 comprises a base 30 from which A central wall 31 and two lateral walls 32 extend in the insertion direction X, flanking the central wall 31. The two lateral walls 32 and the central wall 31 define the two slots 22. The central wall 31 has a free end 33, and each of the lateral walls 32 has a free end 34. The base 30 has an extension direction substantially perpendicular to the insertion direction X. The two slots 22 are defined by the base 30 and the cover 21 in the insertion direction X.

[0100] In the example considered, each of the free ends 34 of the side walls 32 includes one of the inclined ramps 23. The support 20 therefore includes two inclined ramps 23 which slide, during insertion, each on one of the inclined ramps 23 of the cover 21.

[0101] As can be seen in [Fig. 6], the central wall 31 is hollow and has straight reinforcements 35 extending along the insertion direction X and not extending to the free end 33. These reinforcements 35 are spaced apart. The central wall 31 has three identical ones here.

[0102] In the example considered, the central wall 31 and the side walls 32 include flutes 40 which cooperate with the crossbars. The flutes 40 extend on either side of the crossbars. Each crossbar cooperates with flutes 40 of the central wall 31 and with flutes 40 of one of the two side walls 32.

[0103] In the example considered, the gadroons 40 are straight in the insertion direction X. The gadroons are plastically deformable, in particular by the placement of the omnibus bars 10 in the slots 22 and by the sliding of the support 20 relative to the cover 21.

[0104] In the example considered, the base 30 may have two fixing passages 42 for fixing the fixing device 11 on the housing 120. The fixing passages 42 have an axis parallel to that of the insertion direction X. The support 20 has a reinforcing ring 43 around the fixing passage 42.

[0105] In the example considered, the fixing passages 42 receive fixing elements 44 for fixing the support 20 onto the housing 120. Here, screws.

[0106] In the example considered, the base 30 also includes two guide pins 50 which each fit into a guide hole 51 of the housing 120,

[0107] In the example considered, the base 30 finally includes a set of indexing openings 53 of the omnibus bus set 10. Each indexing opening is crossed by one of the omnibus bars before the omnibus bus set 10 is pinched.

[0108] In the example considered, each indexing opening of the indexing opening set 53 has an axis parallel to that of the insertion direction X and is located in the extension of the slot set 22 along the insertion direction X. The two slots 22 are open in the insertion direction X and in the opposite direction to the insertion direction X.

[0109] In the example considered, each omnibus bar has a protrusion 55 which extends into one of the indexing openings 53. Each protrusion 55 allows, when assembling the support 20 with the omnibus bars 10, to hold the support 20 in position before it is fixed to the housing 120.

[0110] In the example considered, the fastening device 11 includes a means for clipping the cover 21 onto the support 20 to join them together while allowing relative movement in the insertion direction X. The clipping means holds the support and the cover together before assembly and subsequent attachment to the housing. This clipping means is visible in [Fig. 6] and [Fig. 7], which respectively show the support 20 and the cover 21 in isolation.

[0111] In the example considered, the clipping means consists of an elastic tab 58 coming from the material with the cover 21 which passes through a clipping opening 59 provided in the base 30 of the support 20. Once the elastic tab 58 is clipped, the cover 21 is linked to the support 20 and can slide in the clipping opening 59.

[0112] In the example considered, the cover 21 comprises a bottom 60, substantially flat, and two lateral edges 61. Each of the lateral edges 61 comprises one of the inclined ramps 23. The support 20 slides, during insertion, each on each of the inclined ramps 23 of the cover 21.

[0113] In the example considered, the cover 21 includes a central edge 62. The central edge 62 cooperates with the central wall 31 in order to wedge the support 20 on the cover 21 in a direction transverse to the insertion direction X during assembly.

[0114] In the example considered, each omnibus bar 10 rests on the bottom 60 of the cover 21 when the support 20 pinches said omnibus bars 10.

[0115] In the example considered, the cover 21 includes external bosses 63. The external bosses 63 allow a distribution of the forces of the cover 21 on the housing 120. The external bosses 63 extend over the bottom 60 and over the lateral edges 61.62.

[0116] In connection with Figures 1 to 7, an example of a method for assembling the busbar 10 of the conductor assembly 1 in the electrical equipment 100 comprises the following steps: - Installation of support 20 on the omnibus busbar set 10 - Fixing the cover 21 onto the support 20 to link them together while at allowing a relative movement in the insertion direction X, - Movement of the support 20, the omnibus busbar set 10 and the cover 21 towards the housing 120 according to the insertion direction X, - Fixing support 20 onto housing 120 of electrical equipment 100.

[0117] In the insertion direction X, the cover 21 comes into contact with the housing 120 at the base 25. The cover 21 is then stationary relative to the housing 120, and it is the support 20 that is mobile relative to the cover 21 and the housing 120. The support 20 slides on the cover 21 via the inclined ramps 23 in the insertion direction X. The volume of the slots decreases until the support 20 pinches the busbar 10. When the busbars are pinched, the mounting slots 42 of the support 20 are in position to receive the fasteners 44 that secure the support 20 to the housing 120. The busbar is then fixed to the support 20 and thus to the housing 120.
