  • the free end of the second busbar part 4b has a slot 30 through which two spring tongues 31 are formed.
  • the two spring tongues 31 lie on a common plane. With the aid of this slot 30, the spring tongues 31 exert a clamping force when the free end of the second busbar part 4b is pressed into the opening in the first busbar part 4a.

Abstract

La présente invention concerne une borne de connexion de conducteur (1) pour serrer un conducteur électrique (2, 2a) avec un boîtier en matière isolante (11), un élément de force (5) et un dispositif de rail conducteur (3). L'élément de force (5) est conçu de manière interactive avec le dispositif de rail conducteur (3) pour exercer une force de serrage sur le conducteur électrique (2, 2a) serré contre le dispositif de rail conducteur (3). Le dispositif de rail conducteur (3) présente deux parties de rail conducteur (4a, 4b), logées en regard l'une de l'autre et mobiles l'une par rapport à l'autre, pour serrer le conducteur électrique (2, 2a) entre les deux parties de rail conducteur (4a, 4b). Les deux parties de rail conducteur (4a, 4b) sont conçues pour être, dans l'état serré, chacune en contact électroconducteur direct avec le conducteur de sortie (2b, 16) et fournir une liaison directe, électriquement parallèle entre le conducteur électrique (2, 2a) serré et le conducteur de sortie (2b, 16).
