    [0001] TECHNICAL FIELD The invention relates to a connector designed to electrically connect a system comprising an electric motor and a compressor of a cooling system for a vehicle, such as a car, to a motor vehicle. power source. More specifically, the invention relates to a connector 10 for electrically connecting the end of a cable to a terminal, which connector comprises a housing adapted to receive the end of at least one cable and means for securing the end of the cable in the case. BACKGROUND OF THE INVENTION The connector according to the present invention is adapted for use in the refrigeration circuit of a motor vehicle. The connector is particularly adapted to connect an electrically driven compressor to a power source. Traditionally, this compressor is of the mechanical type and is rotated by a belt or pulley which is connected to the internal combustion engine of the vehicle. The number of hybrid vehicles, namely vehicles having an internal combustion engine coupled to an electric motor or fully electric vehicles, is steadily increasing due to the scarcity of fossil fuels used for internal combustion engines. The mechanical energy that is normally available in the case of internal combustion engines for driving the compressor is less available in hybrid cars and even completely absent in a fully electric vehicle. In addition, for reasons of overall efficiency, the preferred solution for driving the compressor in a hybrid or electric vehicle is an electric motor replacing the belt or pulley. A complicating factor is that a particular vehicle model of a manufacturer can be sold in a first version with an internal combustion engine comprising a mechanical compressor, and in a second version with an electric propulsion type motor that requires a compressor electric.
    [0002] These two types of compressors, mechanical and electrical, rely on different technologies that require the use of different lubricants. The presence of a high electrical potential in an electric compressor requires the use of a dielectric fuel having electrical insulation properties that are superior to those of conventional lubricants used for a mechanical compressor. In addition, if both lubricants are used for different versions of a vehicle produced on the same production platform, manufacturers must manage the presence and use of both types of lubricant during vehicle assembly.
    [0003] In order to avoid problems related to the use of lubricants in a refrigerant circuit in a vehicle or any other problem during the production and assembly of vehicles, the invention proposes a connector which ensures both the electrical contact and the sealing to connect an electric motor for a mechanical compressor to a power source. The purpose is to allow the use of the electric motor in an environment comprising a conventional non-dielectric lubricant. In the prior art, it is known to use a specific waterproof connector comprising a plurality of wires which are inserted into the connector via wire guides, which wires comprise pinched contacts on their ends. During the assembly process, the contacts in the connector must be properly aligned with the passages formed in the connector so that the terminal can enter the connector and make electrical contact with the contacts. Each passage must be properly sealed.
    [0004] The production of this known connector is relatively long and therefore relatively expensive. In industry, particularly the automotive industry, there is a continuing need to improve the performance of auto parts and reduce production time and production costs. There is thus a need for an improved connector specifically designed to electrically connect an electrically driven compressor.

According to one embodiment of the invention, the opening of said at least one groove comprises chamfers which facilitate the entry of said at least one cable into said at least one groove.
    [0006] According to one embodiment of the invention, said at least one groove is disposed in the removable cover and, during assembly of the connector housing and the removable cover, the connector housing is adapted to close at least partially the opening said at least one groove.
    [0007] According to one embodiment of the invention, the removable cover comprises means for receiving a pinched contact at the end of said at least one cable in the connector housing.
    [0008] According to one embodiment of the invention, the removable cover comprises a seal with at least one opening, the seal being designed to be placed in the removable cover so that said at least one opening of the seal is aligned with the passage in the connector housing, the seal being adapted to seal around at least one sleeve around said at least one terminal pin once the terminal pin is disposed in the connector housing.

DETAILED DESCRIPTION OF THE INVENTION While specific embodiments of the invention will now be described in detail, it should be understood that the invention may be practiced otherwise than in accordance with this description. The descriptions and examples that follow are intended to be illustrative and not limiting. It will thus be apparent to those skilled in the art that modifications can be made to the invention as described without departing from the scope of disclosure. FIG. 1 schematically represents an assembly 10. Typically, the assembly 10 can be used in a thermodynamic circuit, for example a cooling or heating circuit used in a vehicle such as a car. The assembly 10 comprises an electric motor 1 connected to a mechanical compressor 2. The assembly 10 also comprises a control module 3 for actuating the motor 1 and the mechanical compressor 2. The assembly comprises a terminal 4 in order to electrically connect and closely the motor to the control module 3. In Fig. 1, the terminal 4 comprises three terminal pins, for example, for making an electrical contact. A wall element 5 defines a specific envelope sealed around the motor 1. The terminal 4 protrudes into the wall element 5 as shown in more detail in FIG. 3. In the present invention, the terms "terminal" and "terminal pin" Are used. The term "terminal" refers to the plug that protrudes from the compressor and on which a connector can be attached. The term "terminal pin" refers to the metal portion of the terminal that is designed to make the electrical contact.
    [0009] FIG. 2 shows a connector 20 according to the invention, comprising a connector housing 30. Several contacts (visible through the transparency of the connector housing 30) are arranged in the connector housing 30. Each contact can be pinched on one end of the cable (not shown) as a motor phase cable. The connector 20 is adapted to be connected to the terminal 4. Once the connector 20 is attached to the terminal 4, each terminal pin 4 is in electrical contact with the contacts in the connector 20. The connector 20 also includes a cover removable 21 to maintain the contacts in the connector housing 30 and receive the contacts in their respective positions. The connector housing 30 and the removable cover 21 are designed to attach the removable cover 21 to the connector housing 30 by, for example, snap-fastening. The removable cover 21 also includes a plurality of grooves 22, such as three grooves, for a corresponding number of phase cables to enter the connector 20. As shown in more detail in FIG. 6, the grooves 22 have an opening such as an open end. in order to easily assemble the phase cables in the grooves 22. Thus, the structure of the removable cover 21 ensures that the cables are received and fixed in the correct position in the grooves 22. The removable cover 21 and the connector housing 30 are formed so as to at least partially close the open end of the grooves 22 to maintain the phase cables 40 in the grooves 22. The assembly of the connector housing 30 and the removable cover 21 provides a better isolation distance around the cables 22. This will be discussed in more detail in the context of FIG. 7. FIG. 3 shows a section of the connection between a connector 20. and terminal 4. Terminal 4 provides a perfectly sealed connection through wall 5 and includes a set of three terminal pins 70. Figure 3 shows only two terminal pins 70. Each terminal pin 70 includes an isolator 51 which component usually of glass. The isolator 51 prevents leakage and electrical contact between each terminal pin 70 and a terminal board. The protruding end of each terminal pin 70 further comprises a sleeve 52 which determines the exact distance between the wall member 5 and the connector 20. The sleeve 52 is generally made of a ceramic material. The connector 20 is adapted to be fixed to the protruding end of the terminal pins 70 to provide electrical contact between the terminal 4 and several cables 40. The end of each cable 40 comprises a contact 41. The contact 41 is normally clamped on the end of a cable 40 and is adapted to contact the terminal pin 70 and allow electrical contact. In the removable cover 21, a recess 24 is adapted to receive a seal 60 or an insert. The shape of the recess 24 corresponds to the shape of the seal 60 so that the seal 60 can be positioned in the recess 24. The seal 60 forms a seal providing adequate sealing around the sleeve 52 to prevent current leakage between contact 41 and terminal plate 53. Seal 60 consists of any acceptable material, such as rubber. HNBR or EPDM are commonly used for this purpose in refrigeration applications. In FIGS. 3, 4 and 5, the seal 60 is designed to seal the contact with a terminal 4 having three terminal pins 70. FIG. 4 shows a top view of the seal 60. The seal 60 has an asymmetrical shape with a main body 61 and a protruding tongue 62. The asymmetrical shape and the protruding tongue 62 thus form a polarizing means or an anti-error form for assembling the seal 60 in a single correct position in the recess 24. This means for example 20 that the seal 60 can not be assembled upside down. The protruding tongue 62 confirms the presence of the seal 60 in the connector 20, and is visible from the outside. This allows visual inspection after assembly to ensure that the seal 60 is inside and is properly positioned. The seal 60 comprises three openings 63, 64, 65, and each opening 63, 64, 65 allows the passage of a terminal pin 70 and a corresponding ceramic sleeve 52. The size and position of the corresponding holes 63, 64, 65 are designed to coincide with the position of the terminal pins 70 and corresponding sleeves 52. The seal 60 further comprises locating holes 66, 67, 68. The locating holes 66, 67, 68 are through holes which are adapted to be positioned on corresponding protuberances (not shown) formed on the bottom of the recess 24. in the removable cover 21. The three corresponding through holes 66, 67, 68 and the protuberances (not shown) allow the seal 60 to be correctly positioned in the connector 20.
    [0010] FIG. 5 shows a sectional view of the seal 60 along the line AA of FIG. 4. The sectional view of FIG. 5 shows the main opening 64, the positioning hole 66 and the specific shape of the wall portion. of the main hole 64. Figure 5 shows that the asymmetrical seal 60 and arranged so that the tabs 65 are opposite the connector housing 30 to ensure sealing. Figure 6 shows the connector 20 with three phase cables 40, 40 ', 40 "in three different positions, Figure 6 shows the positions during the assembly process of the phase cables 40, 40', 40" in the corresponding grooves 22. When the grooves 22 are open on one side, the assembly of the phase cables 40, 40 ', 40 "is relatively easy in that a phase cable 40, 40', 40" can be pressed into one of the respective grooves 22. The opening of the various grooves 22 is slightly smaller than the external diameter of the phase cables 40, 40 ', 40 "Thus, each phase cable 40, 40', 40" is pushed into a groove 22 using a determined amount of force. Once each of the phase cables 40, 40 ', 40 "has been respectively positioned in a groove 22, the phase cable 40, 40', 40" can not be easily disengaged. The grooves 22 each comprise a chamfer of about 30 ° in order to allow the grooves 22 to open by about 60 ° so that the phase cables 40, 40 ', 40 "can enter the grooves 22. The grooves 22 and the specific dimensions of the grooves cause the phase cables 40, 40 ', 40 "to be pressed into the grooves 22. The presence of a 60 ° chamfer offers considerable assistance during the assembly of the connector 20. In fact, since the phase cables 40, 40 ', 40 "each comprise a contact 41 at their end, the fixing of the contacts 41 on the cables 40, 40', 40" can be done before the cables 40 , 40 ', 40 "are fixed in the grooves 22. Thus, unlike the prior art grooves in the form of through holes, it is not necessary in the present invention for the cables to be pushed to through the grooves before attaching the contacts 41 to the respective ends of the cables. , the opening of the grooves 22 of the present invention advantageously avoids the technical constraints for fixing the contacts 41. This feature also greatly facilitates all repair work, in the case where the removable cover 21 is damaged and can not more ensure its function. Figure 7 shows a perspective view of the grooves 22 open to receive the phase cables 40, 40 ', 40 ".
    [0011] Once the connector housing 30 and the removable cover 21 are assembled, the connector housing 30 covers a portion L1 of the grooves 22 of the removable cover 21 to hold the cables 40, 40 ', 40 "in the grooves 22 during use. Furthermore, the presence of the cover over a length L1 allows a minimum required distance between the contact 41 disposed in the center and the housing in order to prevent any leakage of current, Figure 7 shows the length L which corresponds to the length of the grooves. Typically, L1 covers at least one-third of the indicated length L of the grooves 22. Typically, L is about 12.4 millimeters (mm), L1 is about 5 millimeters (mm). 8 shows a sequence of three assembly steps 80, 82, 84 of the connector housing 30 and the removable cover 21. In the assembly steps 80 and 82, and for the sake of clarity, a portion of the connector housing 30 is withdrawn to show some ins elements described below. For the sake of clarity, the other elements of the connector are not shown in Figure 8. In the assembly step 80, the connector housing 30 and the removable cover 21 are placed in a position for their assembly. As illustrated in step 80, the interior of the removable cover 21 includes an inclined surface 26 adapted to contact the front end 35 of the housing 30. As shown in the assembling step 82, the front end 35 is guided by the inclined surface 26 to an end position by pushing the connector housing 30. As shown in the assembling step 84, the housing 30 and the removable cover 21 are fully assembled. The rear end 37 comprises a small edge which is fixed with a notch 27 of the removable cover 21 so that the front end can be snap-fastened. The role of the connector 20 is to electrically connect the motor 1 to a control module 3. Thus, the connection of the connector 20 to the terminal assembly 4 is critical because the terminal 4 passes through the wall element 5 of the housing. connector 30 around the motor 1. Connector 20 of the present invention provides adequate sealing once connector 20 is put in place to ensure a secure connection.

In fact, since the phase cables 40, 40 ', 40 "each comprise a contact 41 at their end, the fixing of the contacts 41 on the cables 40, 40', 40" can be done before the cables 40 , 40 ', 40 "are fixed in the grooves 22. Thus, unlike the prior art grooves in the form of through holes, it is not necessary in the present invention for the cables to be pushed to through the grooves before attaching the contacts 41 to the respective ends of the cables. , the opening of the grooves 22 of the present invention advantageously avoids the technical constraints for fixing the contacts 41. This feature also greatly facilitates all repair work, in the case where the removable cover 21 is damaged and can not more ensure its function. Figure 7 shows a perspective view of the grooves 22 open to receive the phase cables 40, 40 ', 40 ".
    [0021] Once the connector housing 30 and the removable cover 21 are assembled, the connector housing 30 covers a portion L1 of the grooves 22 of the removable cover 21 to hold the cables 40, 40 ', 40 "in the grooves 22 during use. Furthermore, the presence of the cover over a length L1 allows a minimum required distance between the contact 41 disposed in the center and the housing in order to prevent any leakage of current, Figure 7 shows the length L which corresponds to the length of the grooves. Typically, L1 covers at least one-third of the indicated length L of the grooves 22. Typically, L is about 12.4 millimeters (mm), L1 is about 5 millimeters (mm). 8 shows a sequence of three assembly steps 80, 82, 84 of the connector housing 30 and the removable cover 21. In the assembly steps 80 and 82, and for the sake of clarity, a portion of the connector housing 30 is withdrawn to show some ins elements described below. For the sake of clarity, the other elements of the connector are not shown in Figure 8. In the assembly step 80, the connector housing 30 and the removable cover 21 are placed in a position for their assembly. As illustrated in step 80, the interior of the removable cover 21 includes an inclined surface 26 adapted to contact the front end 35 of the housing 30. As shown in the assembling step 82, the front end 35 is guided by the inclined surface 26 to an end position by pushing the connector housing 30. As shown in the assembling step 84, the housing 30 and the removable cover 21 are fully assembled. The rear end 37 comprises a small edge which is fixed with a notch 27 of the removable cover 21 so that the front end can be snap-fastened. The role of the connector 20 is to electrically connect the motor 1 to a control module 3. Thus, the connection of the connector 20 to the terminal assembly 4 is critical because the terminal 4 passes through the wall element 5 of the housing. connector 30 around the motor 1. The connector 20 of the present invention provides adequate sealing once the connector 20 is put in place to ensure a secure connection.
