Abstract

L'invention concerne un connecteur à fiches comportant un connecteur mâle (10) et un connecteur femelle, permettant l'enfichage ou le détachage des deux connecteurs (10) de manière à créer ou couper un contact électrique. Le connecteur mâle (10) comporte un corps de connecteur (11) contenant un élément mâle (22) présentant une pièce de connexion et une tige de contact (40), ledit connecteur mâle présentant au moins une chambre de contact allongée (12) pourvue d'une ouverture (99). La chambre de contact allongée présente une surface de paroi intérieure (90) s'étendant longitudinalement, une surface de base perpendiculaire à cette dernière, disposée dans le corps de connecteur, et un côté d'enfichage opposé à celle-ci, comportant l'ouverture (99), de telle manière que la chambre de contact est accessible par l'extérieur au travers de l'ouverture. Dans la chambre de contact (12), la tige de contact (40) de l'élément mâle est disposée parallèlement à la surface de paroi, de la surface de base vers l'ouverture (99). Sur le côté d'enfichage, la surface de paroi comporte des éléments (60) faisant barrière aux doigts, s'étendant dans la chambre de contact, de telle manière qu'un doigt pénétrant dans l'ouverture ne peut pas toucher la tige de contact.
