ARRIERE-PLAN TECHNOLOGIQUE DE L'INVENTION BACKGROUND OF THE INVENTION

Les véhicules électriques doivent être régulièrement rechargés à l'aide d'un connecteur prise de charge alimentée par une station de charge électrique. Cette prise de charge permet alors de charger une batterie se trouvant dans le véhicule. Les câbles sont fixés efficacement et maintenus à leur extrémité par un connecteur de câble électrique appelé aussi connecteur de prise de charge. Le connecteur doit respecter la norme IEC 62196- 1 §26 sur la résistance mécanique aux chocs et le chapitre §33 sur la résistance à l'essai de roulage sur connecteur et la norme IEC 62196-2/fiche standard 2-II sur la forme du connecteur. Des constructeurs automobiles ont sévérisés leurs exigences vis-à-vis de la tenue aux chocs en augmentant le nombre de chocs (500 chocs) auquel le connecteur doit résister. Cela implique dans un premier temps un changement de matériau pour un matériau avec une plus grande résistance aux chocs. Cette modification est insuffisante pour pouvoir passer l'exigence de tenue aux 500 chocs demandés par certains constructeurs automobiles. La rupture du connecteur se fait au niveau d'un boîtier du connecteur femelle porte-contacts appelé aussi enveloppe rigide ou réceptacle. Par la suite le terme enveloppe rigide sera utilisé. L'objet de la présente invention est de fournir une solution qui résout ces inconvénients.  Electric vehicles must be recharged regularly using a charging plug connector powered by a charging station. This charging socket can then charge a battery in the vehicle. The cables are effectively secured and held at their end by an electrical cable connector also called load plug connector. The connector must comply with IEC 62196-1 §26 on mechanical resistance to impact and chapter §33 on resistance to the test of rolling on the connector and the standard IEC 62196-2 / standard form 2-II on the form of the connector. Car manufacturers have tightened their requirements with respect to impact resistance by increasing the number of shocks (500 shocks) to which the connector must withstand. This involves in the first place a material change for a material with greater impact resistance. This change is insufficient to pass the requirement of resistance to 500 shocks requested by some car manufacturers. The breakage of the connector is at the level of a housing of the female connector-contact connector also called rigid envelope or receptacle. Subsequently the term rigid envelope will be used. The object of the present invention is to provide a solution that overcomes these disadvantages.
