  • the lugs 23 to 26 are lobe-shaped and provided with bevels 27 towards the contact knife 10. Since the flat plug contact element is made from a stamped and bent part, the tab-shaped projections 23 to 26 can be formed in a simple manner by separating cuts which are provided at least in the side walls 7, 8.
  • the shoulders 23 to 26 and thus the corresponding separating cuts are provided in the area of the transition from the bottom wall 6 of the intermediate area Z to the side walls 7, 8. This can be seen particularly clearly in FIGS. 2, 3 and 5.

Abstract

L'invention concerne un organe de contact (1) constitué d'une pièce cintrée estampée (2) comportant un élément de connexion de ligne (4), une zone intermédiaire de forme cubique (z) et une lame de contact (10) faisant saillie par rapport à cette dernière. La zone intermédiaire (Z) comprend des épaulements (23-26) espacés latéralement dans la zone des deux parois latérales (7, 8). Les dimensions des épaulements sont adaptées à la différence entre la section de la zone intermédiaire et la section (B) d'une chambre de contact (34) existante, de taille plus importante. L'organe de contact peut ainsi être produit avec la même séparation, au moyen d'un outil de façonnage existant, et peut être enfiché de façon compatible avec les chambres de contact existantes.
