Definitions
- the technical sector of the present invention is that of compressors constituting a refrigerant circuit fitted to a motor vehicle.
- the refrigerant fluid is conventionally circulated inside an air conditioning circuit via a compressor.
- this compressor is mechanical type because its rotation is driven by means of a pulley connected to the internal combustion engine by a belt.
- hybrid vehicles that is to say with internal combustion engine coupled to an electric motor, or all electric, that is to say exclusively powered by an electric motor, is constantly increasing because of the rarefaction of fossil fuels that fuel vehicles equipped with internal combustion engines.

- Figure 11 is a side sectional view of the terminal block connected to connection terminals of the compressor of Figure 10.
- FIG 1 illustrates a schematic view of an electric compressor 9 according to the invention and its main components.
- the compressor 9 is an electric compressor in that it incorporates an electric motor 2 which drives a compression mechanism 3.
- the electric motor 2 comprises a stator and a rotor integral with a motor shaft which extends longitudinally along an axis U as shown in Figure 1.
- the compression mechanism 3 comprises fixed parts and moving parts, the latter being rotated by the shaft of the electric motor 2.
- the compression mechanism 3 is of the spiral compression type ( Scroll in English) or of the pallet type or the piston type, these examples being given for illustrative purposes without limiting the scope of the invention.
- the compressor 9 further comprises a control circuit 1 of the electric motor 2.
- This control circuit 1 is notably an inverter (inverter in English) transforming a stream of continuous form coming from the vehicle into a stream of sinusoidal shape supplying the electric motor 2.
- the compressor 9 is delimited vis-à-vis its external environment by a housing.
- This housing is an aluminum piece or aluminum alloy, hollow circular shape comprising a peripheral wall which delimits an internal volume.
- This housing comprises, in this example, at least three compartments, which take the form of cavity or housing formed inside the housing, in which are respectively mounted the control device 1, the electric motor 2 and the compression mechanism 3 as shown in Figure 1. These compartments are separate volumes separated from each other by at least one wall. It will therefore be understood that these compartments may be delimited by a single peripheral part which forms the housing or, for example, by separate sub-housings dedicated to each compartment and assembled together to form the compressor 9.
- the compressor 9 comprises a main housing, forming a motor compartment 20, which houses the electric motor 2 and on which is reported, at a first end, a housing forming a control compartment 10 in which the device is housed. control 1 and at a second end, opposite the first end relative to the electric motor 2, a housing forming a compression compartment 30 in which is housed the compression mechanism 3.
- the engine compartment 20 is interposed between the compartment control 10 and the compression compartment 30.
- a fluid or mixture consisting of a coolant mixed with a lubricant enters the engine compartment 20 and circulates around and in the electric motor 2.
- the coolant is a subcritical fluid such as for example the R704a but it may also be a supercritical refrigerant fluid such as for example carbon dioxide known as R244.
- the lubricant is for example a polyalkylene glycol type compound.
- the fluid circulates in the engine compartment 20 and then in the compression compartment 30 in which the compression mechanism 3 is housed.
- the latter ensures the increase of pressure and temperature of the refrigerant fluid necessary for the thermodynamic operation of the compressor 9.
- the engine compartment 20 is separated from the control compartment 10 by a wall 4 which prevents the penetration of the fluid into the control compartment 10. It is thus clear that the fluid present in the engine compartment 20 does not circulate in the control compartment 10 to protect the controller 1 which includes elements having high electrical potentials.
- control device 1 supplies the electrical energy to the electric motor 2. Since these components are in two separate compartments, it is necessary to electrically connect the control device 1 to the electric motor 2. To do this, a control device electrical connection 5 is mounted at the interface between the engine compartment 20 and the control compartment 10.
- the connection device 5 comprises a plurality of connection terminals 6 of the control device 1 connected to a connection block 7 of the electric motor 2.
- connection terminals 6 are three in number and are respectively received in three openings 74 of the connection block 7.
- each terminal 6 comprises a conductive rod 61 mounted in an orifice of the wall 4, the ends of the rod 61 being projecting respectively in the control compartments 10 and motor 20.
- the connection terminals 6 extend substantially parallel to the axis U of the motor 2.
- each conducting rod 61 is mounted in an insulating plug 62, preferably ceramic, which is secured to the wall 4.
- the plug 62 of each terminal 6 is crimped on the wall 4 and is made of ceramic.
- the connection block 7 is, in this example, a conventional connection block as manufactured industrially by the company TYCO ELECTRONICS.
- connection block 7 comprises a plastic body 71 of generally parallelepipedal shape which extends in length in the direction X, in width in the direction Y and in height in the direction Z as shown in FIGS. 5.
- the connection block 7 further comprises connection elements 72 mounted in the interior volumes of the body 71 which are electrically connected to the motor 2 by electrical cables 73 as shown in FIG. 3.
- the connection block 7 is removable from the connection terminals 6 mounted in the wall 4 so as to allow the mounting of the compressor 9 in a modular manner.
- the terms “back” and “front” are defined with respect to the X axis that is bitterly forward in Figures 4 and 5.
- the terms “low” and “low” are are defined with respect to the Y axis which is oriented from bottom to top in FIGS. 4 and 5.
- the rear part of the body 71 of the connection block 7 is beveled so as to present a smaller width at its rear end than at its center.
- the rear face F1 of the body 71 of the connection block 7 is open to allow the introduction of three connection elements 72.
- connection elements 72 are known to those skilled in the art and will not be detailed further.
- the front face F2 of the body 71 of the connection block 7, for its part comprises a plurality of openings 76 used during the molding of the body 71 of the connection block 7 as shown in Figure 6B.

- the invention proposes to mount an electrical insulation element 8 removably on the connection block 7 and to arrange it between the wall 4 and the connection block 7.
- the electrical insulation element 8 is in the form of a cover 8. It goes without saying that the electrically insulating element 8 can be in various forms, for example in the form of an insulation block, etc. For the sake of clarity, only the term “hood" is used in the following description.
- the insulation cover 8 mainly comprises an interface partition 81 placed between the wall 4 and the connection block 7 which covers the upper face F3 of the body 71, a rear wall 83 arranged to close the rear face F1 of the body 71 and a front wall 82 closing the front openings 76 of the front part of the body 71.
- the insulation cover 8 is in one piece and is adapted to elastically deform during assembly, the insulation cover 8 is then maintained on the connection block 7 by spring effect.
- the interface partition 81 is elastic so as to be deformable when it is mounted on the body of the connection block 7 and thus conform to the shape of the body 71 of the connection block 7.
- the interface partition 81 is flat and extends in the plane (X, Y). Only through openings 85 are formed in the partition 81 to correspond with the connection openings 74 of the body 71. Thus, the interface partition 81 makes it possible to close the mounting openings 75 of the upper face F3 of the body 71 and avoid arcing.
- the diameter of the through openings 85 is substantially equal to that of the insulating plugs 62 of the connection terminals 6 in order to allow a complementary fit of shapes which makes it possible, on the one hand, to increase the electrical insulation during connection 5 and, on the other hand, to prevent the penetration of liquid into the body 71 of the connection block 7 via the connection openings 74.
- FIG. 9 represents, by a continuous line, a potential path of an electric arc C1 which would be formed between the wall 4 and a connection block 7 without an insulating cover 8.
- a C1 electric arc could be formed between a connection element 72 and the wall 4 via a mounting opening 75.
- the insulation cover 8 prevents the formation of such an arc by closing such a mounting opening 75.
- a dashed line represents the potential path of an electric arc C2 which would form between the wall 4 and a connection block 7 with an insulation cover 8.
- This electric arc C2 must circumvent, on the one hand, the isolation plug 62 and, on the other hand, the interface partition 81 and the front wall 82 of the cover 8 to connect a connection element 72 and the wall 4 via a connection opening 74.
- a such C2 path is very long and ensures effective electrical insulation preventing arc formation.
- Such an insulation cover 8 also makes it possible to avoid arcing between the conductive rods 61 since the insulating cover 8 makes it possible to enclose the ceramic insulating plugs 62 as shown in FIG. .
- the front partition 82 of the cover 8 is flat and extends in the plane (Y, Z), that is to say orthogonally to the interface partition 81.
- the insulating cover 8 further comprises lateral partitions 87 of triangular shape which extend in the plane (X, Z).
- the front partition 82 makes it possible to close the openings 76 of the front face F3 of the body 71 and thus makes it possible to avoid the formation of an electric arc from the front openings 76.
- the rear partition 83 of the cover 8 has a shape complementary to the rear part of the body 71 which is beveled (see Figure 5) so as to allow optimum cooperation between the connection block 7 and its cover 8.
- the rear partition 83 comprises mounting pins 86 which extend parallel to the plane (X, Y) and which are arranged to cooperate with the rear part of the connection block 7.
- the rear partition 83 of the cover 8 makes it possible, on the one hand, to close the rear face F1 of the connection block and, on the other hand, to allow the passage of the connection cables 73 connected to the connecting elements 72 mounted in the body 71.
- the rear wall 83 comprises a guide sheath 84 extending along the X axis and which comprises three channels for respectively guiding the three connecting cables 73 connecting the three elements. connection 72.
- the hood is generally in the form of a U in which the base of the U corresponds to the interface partition 81 while the branches of the U correspond to the front and rear walls 82 and 83.
- the insulating cover 8 comprises locking means 88 configured to allow mounting and disassembly of the cover 8 vis-à-vis the connection block 7.
- the locking means is are in the form of a lug 88 formed from the front wall 82 and projecting towards the inside of the cover 8. Due to its shape, the lug 88 is able to hook onto the connection block 7 by taking advantage of the flexibility of the interface partition 81. As will be detailed later, the combination of a lug 88 and a flexible interface partition 81 allows easy mounting of the cover 8 on the connection block 7.
- connection cables 73 are first introduced into the channels of the guiding sheath 84 of the cover 8 from the rear. Then, the free ends of the connecting cables 73 are electrically connected to the connection elements 72 as shown in FIG. 8B. The connection elements 72 are then introduced into the body 71 from the rear face F1 and thus be positioned opposite the connection openings 75 of the upper face F3 of the body 71 (FIG. 8C).
- connection block 7 is introduced into the cover 8 by pulling the connection cables 73 backwards so as to make cooperate the rear portion of the body 71 with the rear wall 83 of the cover 8 as shown in Figure 8D.
- the lug 88 of the front portion 82 of the cover 8 prevents the cooperation of the cover 8 with the connection block 7.
- the interface partition 81 of the cover 8 is bent (see arrow D) so that the connection block 7 avoids the lug 88 and allows the contacting of the upper face F3 of the body 71 with the interface partition 81.
- connection block 7 can then simply be removed from its cover 8.
- connection openings 75 of the connection block 7 are visible, the other openings being closed by the insulation cover 8.
- the cover 8 advantageously forms a thin insulation skin around the connection block 7.
- connection block 7 (on which is mounted the cover of 8) is connected to the connection terminals 6 by introducing the conductive rods 61 of the connection terminals 6 into the connection openings 75 of the body 71 (via the orifices 85 of the cover 8) in order to come into contact with the connection elements 72
- a seal 91 is threaded onto each connecting rod 61 projecting into the engine compartment 20 of the an annie coming to bear on the ceramic plug 62 of said connection terminal 6.
- the seal 91 extends in a plane transverse to the axis in which the connection terminal 6 extends as 10 and 11.
- Such a seal 91 preferably annular, improves the sealing of the connection between a connecting rod 61 and the connection block 7 by preventing any liquid penetration into the connection. connection block 7 via a connection opening 74.
- each seal 91 makes it possible to increase the insulation distance, on the one hand, between the wall 4 and the connection block 7 and, on the other hand, between two rods of 61.
- each seal 91 is made of rubber but it goes without saying that any other elastic material compatible with the environment of the compressor could be suitable (HNBR, etc.).
