  • the compressor is for example driven by an electric motor and the assembly formed by the compressor and the motor is called motorcycle compressor.
  • the compressor and the motor associated with it are commonly encapsulated in an airtight envelope.
  • the component thus produced is subsequently called a hermetic compressor.
  • the electrical connection of the motor passes through the hermetic envelope and the hermetic compressor is delivered with several terminals coming out of the envelope on which a power cable is connected during the installation of the thermodynamic machine.
  • Such a hermetic compressor is for example known from the document EP 0 422 336 A1 .

To ensure the proper connection of the specific conductor to the earth terminal, it implements a particular means of connection distinct from the connection means of the other conductors of the power cable carrying the electrical power.
  • the power conductors are terminated by lugs simply plugged into the power terminals and the grounding conductor is terminated by a lug screwed to the ground terminal.
  • connection of the various conductors of the cable to the terminals through the envelope of the hermetic compressor is subject to error which can cause an immediate or short term destruction of the compressor.

  • the antireturn means prohibit the movement of the housing in a direction opposite to the direction of insertion, only by means of traction on the housing and allow movement of the housing, in a direction opposite to the direction of insertion, combining the traction in a direction opposite to the direction of insertion with another maneuver distinct from the traction.
  • This embodiment can be implemented independently of the fact that the mechanical connection piece is monobloc and independently of the presence of two parts: base and cover, forming the housing.

  • we try to disconnect the housing 20 by exerting on the washer 31 a force in a direction opposite to the direction 22, or the fins 33 bearing on the rod 13, tend to see their inclination to be reduced which increases the clamping force of the washer 31 on the rod 13.
  • the tearing of the housing 20 to disconnect can also break the attachment of the piece 30 in the housing 20.
  • the housing 20 is for example made of plastic material obtained by molding. Grooves made in the housing 20 and in the plane 32 may serve to anchor the workpiece 30. The disconnection of the housing may for example break the grooves and thus break the anchoring of the workpiece 30 in the housing 20.
  • the housing 20 and the power cable 21 at the end of which is disposed the housing 20 can be made in the factory thus avoiding any risk of poor connection of the cable 21 on the various terminals out of the sealed envelope 11. It can be necessary to intervene on site during the use of the equipment to repair the wiring.
  • the housing 20 comprises two parts: a base 37 and a cover 38.

  • the cover 38 can be removably attached to the base 37.
  • the removable attachment is realized for example by screws or by clipping.
  • the base 37 is made of an electrically insulating material so as to avoid any electrical contact between the components situated inside the casing 20 and the hermetic envelope 11. More generally, the casing 20 comprises an electrically insulating material arranged in order to avoid any electrical contact between components inside the housing 20 and the hermetic envelope 11.

  • the tongue 42 may have a width of 6.3 mm which can accommodate a lug 41 that can be easily obtained from connector manufacturers.
  • the lug 41 can be crimped or welded on the end of the grounding conductor 40.
  • the piece 30 has shapes defined so as to be formed in a folded sheet of constant thickness. These forms are clearly visible on the figure 3 .
  • the tongue 42 must have a thickness of about 0.8 mm. It is understood that the values given for the dimensions of the lug 41 are only examples. Any other value is possible without departing from the scope of the invention. Nevertheless, depending on the material used to make the part 30, the thickness necessary for producing the washer 31 and in particular the fins 33, may be different from the thickness of the tongue 42. To adapt to the divergent stresses of the thickness of the washer 31 and the tongue 42, the tongue 42 comprises two folds 43 and 44 to increase its functional thickness vis-à-vis the lug 41. To resume the example of dimension given above, we can achieve the piece 30 in a 0.4 mm thick sheet while connecting a lug 41 provided for a tongue of 0.8 mm.

  • the anti-return effect is effective when an operator tries to remove the housing 20 by exerting a pull in a direction opposite to the direction of insertion 22 on the housing 20. It is however possible to configure the antiretor means to allow disengagement of those by means of a complementary maneuver distinct from a traction in a direction opposite to the direction of insertion 22.

Description

L'invention concerne le raccordement électrique d'un compresseur hermétique par exemple utilisé pour la réfrigération domestique ou commerciale et le conditionnement de l'air.The invention relates to the electrical connection of a hermetic compressor for example used for domestic or commercial refrigeration and air conditioning.

De façon plus générale, dans une machine thermodynamique, un compresseur est utilisé pour comprimer un fluide frigorigène avant de le faire circuler dans un échangeur permettant de refroidir le fluide au contact d'une source chaude.More generally, in a thermodynamic machine, a compressor is used to compress a refrigerant before circulating it in an exchanger for cooling the fluid in contact with a hot source.

On connaît des compresseurs de divers types, par exemple alternatifs ou rotatifs. Le compresseur est par exemple entrainé par un moteur électrique et l'ensemble formé par le compresseur et le moteur est appelé moto compresseur. Dans les machines frigorifiques, le compresseur et le moteur qui lui est associé est couramment encapsulé dans une enveloppe hermétique. Le composant ainsi réalisé est appelé par la suite compresseur hermétique. Le raccordement électrique du moteur traverse l'enveloppe hermétique et le compresseur hermétique est livré avec plusieurs bornes sortant de l'enveloppe sur lesquelles on raccorde un câble d'alimentation lors de l'installation de la machine thermodynamique. Un tel compresseur hermétique est par exemple connu du document EP 0 422 336 A1 . Le câble se termine par des moyens de connexions électriques venant s'enficher sur les bornes d'alimentation du compresseur hermétique. Cet ensemble est ensuite recouvert par un capot électrique pour assurer la sécurité de l'équipement et des personnes utilisant l'équipement mettant en oeuvre la machine thermodynamique. Par ailleurs, un moyen de raccordement à la terre, connecté à une borne particulière traversant l'enveloppe, permet de raccorder l'équipement à une connexion de terre fournie par le réseau électrique d'alimentation de l'équipement.Compressors of various types, for example reciprocating or rotary, are known. The compressor is for example driven by an electric motor and the assembly formed by the compressor and the motor is called motorcycle compressor. In refrigerating machines, the compressor and the motor associated with it are commonly encapsulated in an airtight envelope. The component thus produced is subsequently called a hermetic compressor. The electrical connection of the motor passes through the hermetic envelope and the hermetic compressor is delivered with several terminals coming out of the envelope on which a power cable is connected during the installation of the thermodynamic machine. Such a hermetic compressor is for example known from the document EP 0 422 336 A1 . The cable ends with means of electrical connections coming on the power supply terminals of the hermetic compressor. This assembly is then covered by an electric cover to ensure the safety of equipment and people using the equipment implementing the thermodynamic machine. Furthermore, a ground connection means, connected to a particular terminal through the envelope, makes it possible to connect the equipment to a ground connection provided by the power supply network of the equipment.

Cette borne, appelée borne de terre, est raccordée à un conducteur électrique spécifique du câble d'alimentation. Ce conducteur spécifique est généralement isolé au moyen d'un isolant de couleur particulière vert et jaune. Pour s'assurer de la bonne connexion du conducteur spécifique à la borne de terre, on met en oeuvre un moyen particulier de connexion distincte des moyens de connexion des autres conducteurs du câble d'alimentation véhiculant la puissance électrique. Par exemple, les conducteurs de puissance sont terminés par des cosses simplement enfichés sur les bornes d'alimentation et le conducteur de terre est terminé par une cosse vissée sur la borne de masse.This terminal, called the earth terminal, is connected to a specific electrical conductor of the power cable. This specific conductor is usually insulated with a special green and yellow color insulator. To ensure the proper connection of the specific conductor to the earth terminal, it implements a particular means of connection distinct from the connection means of the other conductors of the power cable carrying the electrical power. By for example, the power conductors are terminated by lugs simply plugged into the power terminals and the grounding conductor is terminated by a lug screwed to the ground terminal.

Le raccordement des différents conducteurs du câble sur les bornes traversant l'enveloppe du compresseur hermétique est sujet à erreur ce qui peut provoquer une destruction immédiate ou à court terme du compresseur.The connection of the various conductors of the cable to the terminals through the envelope of the hermetic compressor is subject to error which can cause an immediate or short term destruction of the compressor.

De plus, le temps de raccordement peut être plus ou moins important suivant l'accessibilité des bornes de connexion dans l'équipement.In addition, the connection time may be more or less important depending on the accessibility of the connection terminals in the equipment.

L'invention vise à fiabiliser le raccordement du câble sur les bornes du compresseur. L'invention vise également à améliorer la rapidité de connexion du câble.The invention aims to make reliable the connection of the cable on the terminals of the compressor. The invention also aims to improve the speed of connection of the cable.

A cet effet, l'invention a pour objet un compresseur hermétique comprenant un groupe moto pompe, une enveloppe hermétique et des moyens de connexion électriques, le groupe moto pompe étant disposé à l'intérieur de l'enveloppe hermétique, les moyens de connexion permettant l'alimentation électrique du groupe moto pompe en traversée de l'enveloppe hermétique, les moyens de connexion comprenant une tige de terre et au moins deux bornes d'alimentation, les moyens de connexion comprennant un boîtier mobile et un câble d'alimentation, le boîtier étant disposé à l'extrémité du câble, la connexion du boitier sur la tige de terre et sur les bornes d'alimentation se faisant par un mouvement de translation, suivant un sens d'insertion, la connexion du boîtier sur la tige de terre compreannant des moyens antiretours interdisant le mouvement du boîtier dans un sens opposée au sens d'insertion, la tige de terre étant formée d'une tige s'étendant hors de l'enveloppe hermétique dans une direction portant le sens d'insertion, caractérisé en ce que le boîtier comprend une pièce mécanique monobloc destinée à assurer la connexion du boîtier sur la tige de terre, en ce que le boîtier comprend deux parties : une embase et un capot, en ce que la pièce mécanique est solidaire de l'embase, en ce que le capot est fixé de façon amovible sur l'embase et en ce que l'embase est réalisée dans un matériau isolant électriquement de façon à éviter tout contact électrique entre des composants situés à l'intérieur du boîtier et l'enveloppe hermétique.For this purpose, the subject of the invention is a hermetic compressor comprising a motor pump unit, a hermetic envelope and electrical connection means, the motorcycle pump unit being disposed inside the hermetic envelope, the connection means enabling the power supply of the pump motor unit through the hermetic envelope, the connection means comprising an earth rod and at least two power supply terminals, the connection means comprising a mobile housing and a power cable, the housing being arranged at the end of the cable, the connection of the housing on the earth rod and on the supply terminals being effected by a translation movement, in one direction of insertion, the connection of the housing to the earth rod comprising anti-back means preventing movement of the housing in a direction opposite to the direction of insertion, the earth rod being formed of a rod extending out of the sealed envelope only in a direction carrying the direction of insertion, characterized in that the housing comprises a one-piece mechanical part intended to ensure the connection of the housing to the earth rod, in that the housing comprises two parts: a base and a cover, in that the mechanical part is integral with the base, in that the cover is removably attached to the base and in that the base is made of an electrically insulating material so as to avoid any electrical contact between components inside the housing and the airtight envelope.

Dans un mode de réalisation préféré, les moyens antiretours interdisent le mouvement du boîtier dans un sens opposé au sens d'insertion, uniquement au moyen d'une traction sur le boitier et autorisent le mouvement du boîtier, dans un sens opposée au sens d'insertion, en combinant la traction dans un sens opposée au sens d'insertion avec une autre manoeuvre distincte de la traction. Ce mode de réalisation peut être mis en oeuvre indépendamment du fait que la pièce mécanique de connexion soit monobloc et indépendamment de la présence de deux parties : embase et capot, formant le boitier.In a preferred embodiment, the antireturn means prohibit the movement of the housing in a direction opposite to the direction of insertion, only by means of traction on the housing and allow movement of the housing, in a direction opposite to the direction of insertion, combining the traction in a direction opposite to the direction of insertion with another maneuver distinct from the traction. This embodiment can be implemented independently of the fact that the mechanical connection piece is monobloc and independently of the presence of two parts: base and cover, forming the housing.

Par souci de clarté, les mêmes éléments porteront les mêmes repères dans les différentes figures.For the sake of clarity, the same elements will bear the same references in the different figures.

La figure 1 représente un compresseur hermétique 10 comprenant une enveloppe hermétique 11 et un groupe moto pompe non visible sur la figure car disposé à l'intérieur de l'enveloppe hermétique 11. Le compresseur hermétique 10 comprend également des moyens de connexion 12 permettant l'alimentation électrique du groupe moto pompe en traversée de l'enveloppe hermétique 11. Les moyens de connexion 12 comprenant une tige de terre 13 et au moins deux bornes d'alimentation. Dans l'exemple représenté les moyens de connexion 12 comprennent trois bornes d'alimentation 14, 15 et 16 traversant l'enveloppe hermétique 11. Deux des bornes sont destinées à recevoir une phase et la troisième borne de connexion électrique peut recevoir l'une des phases du réseau d'alimentation électrique dans le cas de triphasé.The figure 1 represents a hermetic compressor 10 comprising a hermetic envelope 11 and a motor pump unit not visible in the figure because disposed inside the hermetic envelope 11. The compressor hermetic 10 also includes connection means 12 for supplying power to the pump motor unit through the sealed envelope 11. The connection means 12 comprising a ground rod 13 and at least two power supply terminals. In the example shown, the connection means 12 comprise three supply terminals 14, 15 and 16 passing through the hermetic enclosure 11. Two of the terminals are intended to receive a phase and the third electrical connection terminal can receive one of the phases of the power supply network in the case of three-phase.

Alternativement, en monophasé, l'une des trois connexions peut être raccordée à un composant de protection thermique qui sera décrit ultérieurement. Dans ce cas, les deux autres bornes sont raccordées à un équipement électrique complémentaire non représenté, situé à l'extérieur du compresseur hermétique 10 et permettant par exemple de générer une phase auxiliaire utile pour déterminer le sens de rotation du groupe moto pompe lors de son démarrage. La tige de terre 13 est destinée à recevoir une terre de protection délivrée par le réseau électrique.Alternatively, in single phase, one of the three connections can be connected to a thermal protection component which will be described later. In this case, the other two terminals are connected to a complementary electrical equipment, not shown, situated outside the hermetic compressor 10 and making it possible, for example, to generate an auxiliary phase that is useful for determining the direction of rotation of the motorcycle pump unit during its start-up. The earth rod 13 is intended to receive a protective earth delivered by the electrical network.

Les moyens de connexion 12 comprennent un boîtier mobile 20 et un câble d'alimentation 21, le boîtier 20 étant disposé à une extrémité du câble 21. Le câble 21 comprend par exemple quatre conducteurs isolés véhiculant l'alimentation électrique du compresseur 10.The connection means 12 comprise a mobile housing 20 and a power supply cable 21, the housing 20 being disposed at one end of the cable 21. The cable 21 comprises, for example, four insulated conductors conveying the power supply to the compressor 10.

La connexion du boitier 20 sur la tige de terre 13 et sur les bornes d'alimentation 14, 15 et 16 se fait dans un mouvement de translation, suivant un sens d'insertion repéré par une flèche 22.The connection of the housing 20 on the earth rod 13 and on the supply terminals 14, 15 and 16 is in a translational movement, in a direction of insertion marked by an arrow 22.

La figure 2 représente en coupe le boitier 20 connecté à ses bornes d'alimentation 13, 14 et 16.The figure 2 represents in section the housing 20 connected to its power supply terminals 13, 14 and 16.

La connexion du boîtier 20 sur la tige de terre 13 comprend des moyens antiretours interdisant le mouvement du boîtier 20 dans un sens opposée au sens d'insertion 22.The connection of the housing 20 to the earth rod 13 comprises antirust means preventing movement of the housing 20 in a direction opposite to the direction of insertion 22.

La connexion du boîtier 20 sur la tige de terre 13 peut comprendre des moyens d'arc-boutement sur la tige de terre 13. L'arc-boutement sur la tige de terre 13 permet de réaliser simplement l'antiretour du boîtier 20.The connection of the casing 20 to the earth rod 13 may comprise means of buttressing on the earth rod 13. The bracing on the earth rod 13 makes it possible to simply perform the non-return of the casing 20.

La tige de terre 13 est classiquement formée d'un goujon ou d'une tige filetée dont une partie filetée s'étend hors de l'enveloppe hermétique 11 dans une direction portant le sens 22. Il est également possible de former la tige de terre 13 à l'aide d'une tige lisse sortant de l'enveloppe hermétique 11.The earth rod 13 is conventionally formed of a stud or a threaded rod, a threaded part of which extends out of the hermetic envelope 11 in a direction bearing the direction 22. It is also possible to form the earth rod 13 by means of a smooth rod coming out of the hermetic envelope 11.

Il est possible de différencier la connexion électrique sur la tige de terre et la connexion mécanique comprenant les moyens antiretours. La connexion électrique peut être assurée au moyen d'une cosse destinée à entourer la tige de terre 13 et comprenant des moyens élastiques assurant un effort de la cosse sur la tige 13 perpendiculairement à la direction portant le sens 22. La connexion mécanique peut être assurée par un élément pivotant par rapport à la cosse et venant en appui contre la cosse. L'antiretour peut être assuré par gravité en prévoyant un axe de pivotement de l'élément pivotant disposé plus bas que le point de contact entre l'élément pivotant et la tige 13. Ainsi, lors de l'insertion, l'élément pivotant par exemple de forme circulaire glisse contre la tige 13 sans opposer de résistance mécanique, sauf un léger frottement. Par contre, si on tente un mouvement inverse, l'élément circulaire s'arc-boute sur la tige 13 opposant ainsi un effort proportionnel à l'effort exercé pour tenter de désaccoupler le boîtier 20.It is possible to differentiate the electrical connection on the earth rod and the mechanical connection including the means antiretours. The electrical connection can be provided by means of a lug designed to surround the earth rod 13 and comprising elastic means ensuring a force of the lug on the rod 13 perpendicular to the direction bearing the direction 22. The mechanical connection can be ensured by a pivoting element relative to the lug and bearing against the lug. The anti-return can be provided by gravity by providing a pivot axis of the pivoting element disposed lower than the point of contact between the pivoting element and the rod 13. Thus, during insertion, the pivoting element by example of circular shape slides against the rod 13 without opposing mechanical strength, except a slight friction. On the other hand, if we attempt a reverse movement, the circular element is bent on the rod 13 and thus opposing a force proportional to the force exerted to try to uncouple the housing 20.

Avantageusement, la connexion du boîtier 20 sur la tige de terre 13 est définie de façon à ce qu'une déconnexion ne mettant en oeuvre qu'une traction dans un sens opposée au sens d'insertion 22 soit destructrice de la connexion sur la tige de terre 13. Lorsque la connexion mécanique et la connexion électrique sont dissociées, il est possible de définir l'arc-boutement ou plus précisément la position relative de l'axe de pivotement et le point de contact de l'élément pivotant de façon calibrer un effort permettant la déconnection du boîtier, par exemple par déformation de l'élément de fixation de forme circulaire. Il est également possible de définir un effort suffisamment élevé pour dépasser le domaine élastique et entrer dans le domaine de déformation plastique voire entrainer la rupture de la cosse destinée à assurer la connexion sur la tige de terre 13. Une déformation permanente ou une rupture permettra de prouver la déconnexion du boîtier 20.Advantageously, the connection of the housing 20 to the earth rod 13 is defined so that a disconnection using only traction in a direction opposite to the direction of insertion 22 is destructive of the connection on the rod of 13. When the mechanical connection and the electrical connection are dissociated, it is possible to define the bracing or more precisely the relative position of the pivot axis and the point of contact of the pivoting element so as to calibrate a force allowing the disconnection of the housing, for example by deformation of the circular-shaped fastening element. It is also possible to define a sufficiently high effort to exceed the elastic range and enter the field of plastic deformation or cause the rupture of the lug intended to ensure the connection to the earth rod 13. A permanent deformation or breakage will allow prove the disconnection of the housing 20.

Alternativement, dans une variante préférée de l'invention, les connexions électrique et mécanique à la tige de terre 13 sont assurées par une pièce mécanique monobloc 30. Autrement dit, le boîtier 20 comprend une pièce mécanique monobloc destinée à assurer la connexion du boîtier 20 sur la tige de terre 13. La pièce mécanique 30 est solidaire du boîtier 20.Alternatively, in a preferred variant of the invention, the electrical and mechanical connections to the earth rod 13 are provided by a one-piece mechanical part 30. In other words, the housing 20 comprises a one-piece mechanical part intended to connect the housing 20 to the earth rod 13. The mechanical part 30 is integral with the housing 20.

La figure 3 représente la pièce 30 seule. La pièce 30, connectée à la tige de terre 13, est également visible sur la figure 2.The figure 3 represents piece 30 alone. The piece 30, connected to the earth rod 13, is also visible on the figure 2 .

La pièce mécanique monobloc 30 comprend une rondelle 31 percée s'étendant dans un plan 32. La rondelle 31 est destinée à entourer la tige 13 de façon à ce que le plan 32 de la rondelle 31 se place perpendiculairement à la direction portant le sens 22, la borne 13 entrant dans le perçage 34 de la rondelle 31. La rondelle 31 est équipée d'au moins une ailette radiale 33 obturant partiellement le perçage 34 de la rondelle 31, de façon à s'ajuster de façon serrée sur la tige 13.The one-piece mechanical part 30 comprises a washer 31 pierced extending in a plane 32. The washer 31 is intended to surround the rod 13 so that the plane 32 of the washer 31 is placed perpendicular to the direction bearing the direction 22 , the terminal 13 entering the bore 34 of the washer 31. The washer 31 is equipped with at least one radial fin 33 partially closing the bore 34 of the washer 31, so as to fit tightly on the rod 13 .

Avantageusement, la rondelle 31 comprend plusieurs ailettes 33 symétriques. Dans l'exemple représenté sur la figure 3, la rondelle 31 comprend six ailettes 33 s'étendant symétriquement autour de la direction portant le sens 22.Advantageously, the washer 31 comprises several symmetrical fins 33. In the example shown on the figure 3 , the washer 31 comprises six fins 33 extending symmetrically about the direction bearing the direction 22.

La ou les ailettes 33 sont inclinées par rapport au plan 32 de la rondelle 31 de façon augmenter leur inclinaison lors de l'insertion par déformation élastique. Ainsi, à la fin de l'insertion de la rondelle sur la tige 13, la déformation élastique de la ou des ailettes 33 assurent un serrage de la rondelle 31 sur la tige 13 et par conséquent la connexion électrique entre la rondelle et la tige 13. De plus, si on tente de déconnecter le boitier 20 en exerçant sur la rondelle 31 un effort selon un sens opposé au sens 22, la ou les ailettes 33 prenant appui sur la tige 13, tendent à voir leur inclinaison se réduire ce qui augmente l'effort de serrage de la rondelle 31 sur la tige 13. Ceci crée un arc-boutement de la rondelle 31 sur la tige 13 qui empêche la déconnexion du boîtier 20, assurant ainsi l'effet antiretour interdisant le mouvement du boîtier 20 dans un sens opposée au sens d'insertion 22. En augmentant l'effort de déconnexion, il est tout de même possible d'arracher le boîtier 20. Lors de cet arrachement, la ou les ailettes 33 se déforment en inversant leur inclinaison, ce qui peut, en fonction du matériau choisi pour la rondelle, soit déformer de façon irrémédiables la ou les ailettes 33, soit les rompre si le matériau de la rondelle ne possède qu'un faible domaine de déformation plastique. Ceci est par exemple le cas pour un acier trempé à fort pourcentage de carbone. La pièce mécanique 30 est solidaire du boîtier 20. L'arrachement du boîtier 20 pour le déconnecter peut également rompre la fixation de la pièce 30 dans le boîtier 20. Le boîtier 20 est par exemple réalisé en matière plastique obtenu par moulage. Des rainures réalisées dans le boîtier 20 et dans le plan 32 peuvent servir d'encrage à la pièce 30. La déconnexion du boîtier peut par exemple rompre les rainures et donc rompre l'ancrage de la pièce 30 dans le boîtier 20.The fins 33 are inclined relative to the plane 32 of the washer 31 so as to increase their inclination during the insertion by elastic deformation. Thus, at the end of the insertion of the washer on the rod 13, the elastic deformation of the or fins 33 ensure a clamping of the washer 31 on the rod 13 and therefore the electrical connection between the washer and the rod 13 In addition, if we try to disconnect the housing 20 by exerting on the washer 31 a force in a direction opposite to the direction 22, or the fins 33 bearing on the rod 13, tend to see their inclination to be reduced which increases the clamping force of the washer 31 on the rod 13. This creates a jamming of the washer 31 on the rod 13 which prevents the disconnection of the housing 20, thus ensuring the anti-return effect preventing the movement of the housing 20 in a opposite direction to the insertion direction 22. By increasing the disconnection force, it is still possible to tear the housing 20. During this tearing, the fins or fins 33 deform by inverting their inclination, which can , depending on the material chosen p or the washer, is irremediably deform the fins or fins 33, or break if the material of the washer has a small plastic deformation field. This is for example the case for a hardened steel with a high percentage of carbon. The mechanical part 30 is secured to the housing 20. The tearing of the housing 20 to disconnect can also break the attachment of the piece 30 in the housing 20. The housing 20 is for example made of plastic material obtained by molding. Grooves made in the housing 20 and in the plane 32 may serve to anchor the workpiece 30. The disconnection of the housing may for example break the grooves and thus break the anchoring of the workpiece 30 in the housing 20.

Le boîtier 20 et le câble d'alimentation 21 à l'extrémité duquel est disposé le boîtier 20 peuvent être réalisés en usine évitant ainsi tout risque de mauvaise connexion du câble 21 sur les différentes bornes sortant de l'enveloppe hermétique 11. Il peut être nécessaire d'intervenir sur site pendant l'utilisation de l'équipement pour réparer le câblage. A cet effet, le boîtier 20 comprend deux parties : une embase 37 et un capot 38. La pièce mécanique 30 est solidaire de l'embase 37. Le capot 38 peut être fixé de façon amovible sur l'embase 37. La fixation amovible est réalisée par exemple par vis ou par clippage.The housing 20 and the power cable 21 at the end of which is disposed the housing 20 can be made in the factory thus avoiding any risk of poor connection of the cable 21 on the various terminals out of the sealed envelope 11. It can be necessary to intervene on site during the use of the equipment to repair the wiring. For this purpose, the housing 20 comprises two parts: a base 37 and a cover 38. The mechanical part 30 is integral with the base 37. The cover 38 can be removably attached to the base 37. The removable attachment is realized for example by screws or by clipping.

L'embase 37 est réalisée dans un matériau isolant électriquement de façon à éviter tout contact électrique entre les composants situés à l'intérieur du boîtier 20 et l'enveloppe hermétique 11. De façon plus générale, le boîtier 20 comprend un matériau isolant électriquement disposé de façon à éviter tout contact électrique entre des composants situés à l'intérieur du boîtier 20 et l'enveloppe hermétique 11.The base 37 is made of an electrically insulating material so as to avoid any electrical contact between the components situated inside the casing 20 and the hermetic envelope 11. More generally, the casing 20 comprises an electrically insulating material arranged in order to avoid any electrical contact between components inside the housing 20 and the hermetic envelope 11.

Les figures 4 et 5 représentent en perspective l'intérieur du boîtier 20, le capot 38 étant ouvert sur la figure 4 et le capot étant ôté sur la figure 5. Le câble 21 comprend un conducteur électrique de terre 40 se terminant par une cosse de terre 41. Avantageusement, la pièce mécanique monobloc 30 comprend une languette 42 sur laquelle s'enfiche la cosse de terre 41. La languette 42 et la cosse 41 permettent d'intervenir sur la connexion de terre après ouverture du boîtier 20.The figures 4 and 5 represent in perspective the inside of the housing 20, the hood 38 being open on the figure 4 and the hood being removed on the figure 5 . The cable 21 comprises an electrical earth conductor 40 terminating in a ground lug 41. Advantageously, the one-piece mechanical part 30 comprises a tongue 42 on which the earth lug 41 is plugged. The tongue 42 and the lug 41 enable intervene on the earth connection after opening the housing 20.

La languette 42 peut avoir une largeur de 6,3 mm ce qui permet d'accueillir une cosse 41 que l'on peut se procurer facilement chez des fabricants de connecteurs. La cosse 41 peut être sertie ou soudée sur l'extrémité du conducteur de terre 40.The tongue 42 may have a width of 6.3 mm which can accommodate a lug 41 that can be easily obtained from connector manufacturers. The lug 41 can be crimped or welded on the end of the grounding conductor 40.

Avantageusement, la pièce 30 possède des formes définies de façon à pouvoir être formées dans une tôle pliée d'épaisseur constante. Ces formes sont bien visibles sur la figure 3.Advantageously, the piece 30 has shapes defined so as to be formed in a folded sheet of constant thickness. These forms are clearly visible on the figure 3 .

Pour accueillir une cosse 41 classique, la languette 42 doit avoir une épaisseur de l'ordre de 0,8 mm. Il est bien entendu que les valeurs données pour les dimensions de la cosse 41 ne sont que des exemples. Toute autre valeur est possible sans sortir du cadre de l'invention. Néanmoins, en fonction du matériau retenu pour réaliser la pièce 30, l'épaisseur nécessaire pour la réalisation de la rondelle 31 et notamment des ailettes 33, peut être différente de l'épaisseur de la languette 42. Pour s'adapter aux contraintes divergentes d'épaisseur de la rondelle 31 et de la languette 42, la languette 42 comprend deux plis 43 et 44 permettant d'augmenter son épaisseur fonctionnelle vis-à-vis de la cosse 41. Pour reprendre l'exemple de dimension donné plus haut, on peut réaliser la pièce 30 dans une tôle d'épaisseur 0,4 mm tout en y raccordant une cosse 41 prévue pour une languette de 0,8 mm.To accommodate a conventional lug 41, the tongue 42 must have a thickness of about 0.8 mm. It is understood that the values given for the dimensions of the lug 41 are only examples. Any other value is possible without departing from the scope of the invention. Nevertheless, depending on the material used to make the part 30, the thickness necessary for producing the washer 31 and in particular the fins 33, may be different from the thickness of the tongue 42. To adapt to the divergent stresses of the thickness of the washer 31 and the tongue 42, the tongue 42 comprises two folds 43 and 44 to increase its functional thickness vis-à-vis the lug 41. To resume the example of dimension given above, we can achieve the piece 30 in a 0.4 mm thick sheet while connecting a lug 41 provided for a tongue of 0.8 mm.

On a vu plus haut que les moyens de connexion 12 comprennent trois bornes d'alimentation 14, 15 et 16 traversant l'enveloppe hermétique 11. Les bornes d'alimentation 14, 15 et 16 comprennent par exemple chacune une languette d'alimentation s'étendant suivant la direction d'insertion 22. Pour ne pas surcharger les figures, les languettes porteront les mêmes repères que les bornes 14, 15 et 16. Le câble 21 comprend le conducteur de terre 40 et au moins deux conducteurs électriques d'alimentation 47 et 48 se terminant chacun par une cosse, respectivement 50 et 51 destinée à s'enficher chacune sur une des languettes d'alimentation 15 ou 16 lors de la connexion du boîtier 20,It has been seen above that the connection means 12 comprise three supply terminals 14, 15 and 16 passing through the sealed envelope 11. The supply terminals 14, 15 and 16 each comprise, for example, a power supply tab. extending in the direction of insertion 22. To avoid overloading the figures, the tabs will bear the same marks as the terminals 14, 15 and 16. The cable 21 comprises the earth conductor 40 and at least two electrical supply conductors 47 and 48 each terminating in a lug, respectively 50 and 51, each of which is to be plugged onto one of the supply tongues 15 or 16 when the housing 20 is connected,

La figure 6 représente le boîtier 20 ouvert en position sur le compresseur. Avantageusement, le boîtier 20 comprend un composant 55 de protection thermique du compresseur 10. Les bornes d'alimentation comprennent une languette de protection 14 s'étendant suivant la direction d'insertion 22. Le composant de protection thermique 55 comprend un conducteur électrique 56 se terminant par une cosse 57 destinée à s'enficher sur la languette de protection 14. Le câble 21 comprend un troisième conducteur électrique d'alimentation 49 se terminant par une cosse 52. Dans cette variante, le câble 21 comprend donc quatre conducteurs : le conducteur de terre 40 et les trois conducteurs électriques d'alimentation 47, 48 et 49. Le conducteur électrique 49 s'enfiche sur une languette 58 appartenant au composant de protection thermique 55.The figure 6 represents the housing 20 open in position on the compressor. Advantageously, the housing 20 comprises a thermal protection component 55 of the compressor 10. The supply terminals comprise a protection tab 14 extending in the direction of insertion 22. The thermal protection component 55 comprises an electrical conductor 56 terminating in a lug 57 intended to be plugged onto the protection tab 14. The cable 21 comprises a third electrical conductor supply 49 ending in a lug 52. In this variant, the cable 21 thus comprises four conductors: the earth conductor 40 and the three electrical supply conductors 47, 48 and 49. The electrical conductor 49 is is plugged onto a tab 58 belonging to the thermal protection component 55.

L'effet antiretour est effectif lorsqu'un opérateur tente de retirer le boitier 20 en exerçant une traction dans un sens opposée au sens d'insertion 22 sur le boitier 20. Il est toutefois possible de configurer les moyens antiretours pour permettre un désengagement de ceux-ci au moyen d'une manoeuvre complémentaire distincte d'une traction dans un sens opposée au sens d'insertion 22.The anti-return effect is effective when an operator tries to remove the housing 20 by exerting a pull in a direction opposite to the direction of insertion 22 on the housing 20. It is however possible to configure the antiretor means to allow disengagement of those by means of a complementary maneuver distinct from a traction in a direction opposite to the direction of insertion 22.

Cette manoeuvre complémentaire peut par exemple être obtenue en insérant un outil dans le boitier 20 par un orifice prévu à cet effet. L'outil peut par exemple être un tournevis à lame plate se glissant entre une ailette 33 et la tige 13.This complementary maneuver can for example be obtained by inserting a tool in the housing 20 through an orifice provided for this purpose. The tool may for example be a screwdriver with a flat blade sliding between a fin 33 and the rod 13.

La figure 7 représente une pièce monobloc 60 formant une variante à la pièce 30 permettant en plus le désengagement de la liaison. La pièce 60 comprend des moyens alternatifs à l'utilisation d'un outil se glissant entre une ailette 33 et la tige 13 permettant par un mouvement de pression ou de traction la déconnexion sans entrainer la destruction de la pièce 60.The figure 7 represents a one-piece piece 60 forming an alternative to the part 30 further allowing the disengagement of the connection. The part 60 comprises alternative means to the use of a tool sliding between a fin 33 and the rod 13 allowing by a pressure or traction movement the disconnection without causing the destruction of the part 60.

La pièce 60 comprend une rondelle 61 percée semblable à la rondelle 31. La rondelle 61 s'étend dans un plan 62 et est destinée à entourer la tige 13 lors de la connexion du boitier 20 sur la tige 13. La rondelle 61 est équipée d'au moins une ailette radiale 63 obturant partiellement le perçage 64 de la rondelle 61, de façon à s'ajuster de façon serrée sur la tige 13. Ici encore, la rondelle 61 comprend plusieurs ailettes 63 symétriques, 4 dans l'exemple représenté. Les ailettes 63 sont inclinées par rapport au plan 62 de la rondelle 61 de façon augmenter leur inclinaison par déformation élastique lors de l'insertion sur la tige 13. Les ailettes 63 sont disposées par paires chacune des paires d'ailettes 63 venant s'appuyer sensiblement de façon diamétralement opposée sur la tige 13. Comme précédemment une simple traction sur la pièce 60 selon un sens opposé au sens 22, tend à augmenter l'effort de serrage de la rondelle 61 sur la tige 13 en arc-boutant les ailettes 63 sur la tige 13.The piece 60 comprises a washer 61 pierced similar to the washer 31. The washer 61 extends in a plane 62 and is intended to surround the rod 13 when connecting the housing 20 on the rod 13. The washer 61 is equipped with at least one radial fin 63 partially occluding the bore 64 of the washer 61, so as to fit tightly on the rod 13. Here again, the washer 61 comprises several symmetrical fins 63, 4 in the example shown. The fins 63 are inclined relative to the plane 62 of the washer 61 so as to increase their inclination by elastic deformation during insertion on the rod 13. The fins 63 are arranged in pairs each of the pairs of fins 63 coming to rest substantially as diametrically opposed on the rod 13. As previously a simple traction on the part 60 in a direction opposite to the direction 22, tends to increase the clamping force of the washer 61 on the rod 13 by buttressing the fins 63 on the stem 13.

La connexion du boîtier 20 sur la tige 13 comprend des moyens pour libérer l'arc-boutement au moyen d'une manoeuvre distincte de la traction dans un sens opposé au sens d'insertion 22.The connection of the housing 20 to the rod 13 comprises means for releasing the bracing by means of a maneuver distinct from the traction in a direction opposite to the direction of insertion 22.

Dans l'exemple représenté, la pièce monobloc 60 comprend au moins une aile 65, deux ailes 65 dans l'exemple représenté, pouvant être manoeuvrées afin d'écarter les ailettes 63 de la tige 13. Les ailes 65 forment des excroissances s'étendant vers l'extérieur de la rondelle 61. Chaque aile 65 est associée à une paire d'ailettes 63. Chaque aile 65 comprend une zone d'appui, comme par exemple un trou 66 permettant à un outil de tirer sur l'aile 65 perpendiculairement au sens d'insertion 22. Il est par exemple possible d'utiliser une pince à circlips possédant deux doigts venant chacun dans un des trous 66. En manoeuvrant la pince à circlips de façon à écarter les trous de la tige 13, la rondelle 61 se déforme et les ailettes 63 s'écartent de la tige 13 en suivant le mouvement des ailes 65. Alternativement aux trous 66, les ailes 65 peuvent comprendre chacune un épaulement sur lequel peut s'appuyer un outil adapté pour déformer localement la rondelle 61 en l'écartant de la tige 13. La déformation de la rondelle 61 se fait dans le plan 62.In the example shown, the one-piece piece 60 comprises at least one flange 65, two flanges 65 in the example shown, which can be operated in order to move the fins 63 away from the rod 13. The flanges 65 form outgrowths extending to the outside of the washer 61. Each wing 65 is associated with a pair of fins 63. Each wing 65 comprises a bearing zone, such as a hole 66 allowing a tool to pull the wing 65 perpendicularly. In the insertion direction 22, it is possible, for example, to use a circlip pliers having two fingers, each of which fits in one of the holes 66. By operating the circlip plier so as to move the holes from the rod 13, the washer 61 is deformed and the fins 63 deviate from the rod 13 by following the movement of the wings 65. Alternatively to the holes 66, the wings 65 may each comprise a shoulder on which can be supported a tool adapted to locally deform the washer 61 into the écartan t of the rod 13. The deformation of the washer 61 is in the plane 62.

Alternativement, il est possible de déformer localement la rondelle 61 par torsion autour d'un axe 67 perpendiculaire au sens d'insertion 22. Cette torsion peut être réalisée en appuyant sur chacune des ailes 65 dans le sens 22 comme représenté sur la figure 7 au moyen des flèches 68. En appuyant sur les ailes 65 la rondelle 61 se déforme et les ailettes 63 se déforment en sens inverse des ailes 65, en se dégageant de la tige 13. Autrement dit, chacune des ailes 65 est configurée de telle sorte qu'une pression sur l'aile 65 permet d'écarter les ailettes 63 correspondantes de la tige 13.Alternatively, it is possible to locally deform the washer 61 by twisting around an axis 67 perpendicular to the insertion direction 22. This twist can be achieved by pressing each of the wings 65 in the direction 22 as shown in FIG. figure 7 by means of the arrows 68. By pressing the flanges 65, the washer 61 is deformed and the fins 63 deform in the opposite direction to the flanges 65, disengaging from the rod 13. In other words, each of the flanges 65 is configured in such a way that a pressure on the wing 65 allows to separate the corresponding fins 63 of the rod 13.

D'autres ailettes 70 peuvent participer au centrage du perçage 64 sur la tige 13. Les ailettes 63 et 70 sont réparties autour du centre du perçage 64 destiné à coïncider avec l'axe de la tige 13. A la différence des ailettes 63, les ailettes 70 comprennent chacune une extrémité libre 71 recourbée vers l'extérieur afin d'éviter un arc-boutement sur la tige en permettant à l'ailette 70 de glisser contre la tige lorsqu'on déconnecte le boitier 20 de la tige 13.Other fins 70 can participate in the centering of the bore 64 on the rod 13. The fins 63 and 70 are distributed around the center of the bore 64 intended to coincide with the axis of the rod 13. Unlike the fins 63, the fins 70 each comprise a free end 71 bent outwards in order to avoid a jamming on the rod by allowing the fin 70 to slide against the rod when the casing 20 of the rod 13 is disconnected.

L'opération de déformation de la rondelle 61 est réalisée après avoir retiré le capot 38 afin d'accéder à la pièce 60. Il suffit alors de tirer l'embase 37 dans les sens opposé au sens 22 pour déconnecter le boitier 20.The operation of deformation of the washer 61 is performed after removing the cover 38 in order to access the part 60. It is then sufficient to pull the base 37 in the opposite direction to the direction 22 to disconnect the housing 20.

La figure 8 représente l'embase 37 et la pièce 60 en position dans l'embase 37. L'embase 37 est configurée pour permettre l'accès aux ailes 65. La pièce 60 peut comprendre d'autres ailes 72 s'étendant à partir de la rondelle 61 vers l'extérieur. Les ailes 72 permettant un maintien en position de la pièce 60 dans l'embase 37.The figure 8 represents the base 37 and the part 60 in position in the base 37. The base 37 is configured to allow access to the wings 65. The part 60 may comprise other wings 72 extending from the washer 61 to the outside. The wings 72 enabling the part 60 to be held in position in the base 37.
