  • This provision is particularly advantageous for ensuring correct locking at the end of the connection limit and overcomes the resilient features of the locking tab. This contributes to the reliability of the connector assembly according to the invention, even after numerous connection and disconnection actions.
  • the flexible tongue 220 has a hollow 232 on the underside of the locking means 230 disposed in line with the locking means 230, designed to facilitate the deflection of the tongue at this point.
  • the deflection visible in figure 6, is also facilitated by the presence of two grooves 233 in the tongue 220.

Abstract

L'invention concerne un connecteur électrique, comprenant : une première fiche (100) comportant un bras de court-circuitage souple (120) adoptant une position de repos dans laquelle il repose sur une broche pour court-circuiter celle-ci, et une partie de verrouillage (130) présentant un profil à section sensiblement triangulaire ; une seconde fiche (200) conçue pour s'associer à la première fiche ; et une patte de verrouillage souple (220) présentant un profil à section sensiblement triangulaire (230) conçu pour s'associer par ajustement serré au profil de la partie de verrouillage de la première fiche. Lors de la connexion des deux fiches, la patte (220) est dans un premier temps déviée sous l'effet de l'association des deux profils à section sensiblement triangulaire (130, 230) et vient au contact du bras (120) de façon à établir un contact électrique entre la première fiche et la seconde fiche, puis, après s'être dégagée du profil à section sensiblement triangulaire de la première fiche, la patte écarte dans un second temps le bras de sa position de court-circuitage de repos pour le placer dans une position dans laquelle le court-circuitage est supprimé.
