  • a second gap 53b having a predetermined distance or more is formed between the joint portion 51 and the third arm portion 52c. Therefore, even if the first arm portion 52a is elastically deformed by the vibration of the compressor 20, if the fluctuation of the distance between the joint portion 51 and the first arm portion 52a due to the vibration is less than a predetermined distance, the joint portion 51 and the joint portion 51 The connecting portion 52 can be elastically deformed without contacting the first arm portion 52a.

Abstract

L'invention fournit un compresseur électrique type inverseur qui est équipé d'un compresseur, d'un moteur électrique, d'un substrat de commande (41b) commandant le moteur électrique, et d'une partie connexion (50) connectant électriquement le moteur électrique et le substrat de commande (41b). Le moteur électrique possède une pluralité de bornes de connexion de moteur (31a) sous forme d'axes installée dans des parties ouverture (12A) d'un logement de moteur (12). Le substrat de commande (41b) possède une pluralité de trous traversants (41b1). La partie connexion (50) possède : une partie liaison (51) sous forme de plaque ; et une partie raccordement (52) sous forme d'axe dont une extrémité est raccordée à la partie liaison (51), et l'autre extrémité est raccordée aux trous traversants (41b1). La partie raccordement (52) possède : une première partie bras (52a) se prolongeant suivant une première ligne axiale (A1) ; et une seconde partie bras (52b) qui se prolonge suivant une seconde ligne axiale (A2) sécante à la une première ligne axiale (A1).
