Then, from the base leg 39 of the trough 9, a U-shaped tab 10 is freed on three sides and bent from the bottom of the trough by about 90 ° upwards, so that in the base leg 39 of the trough a window-like recess 11 is formed.

Above the one contact bump, the busbar piece 18 has a projection.
  • Such a simple tool-free contactable terminal device in direct plug technology is realized with the simplest means, which is characterized by a simple structure and yet is very reliable, in particular, since the trough-type busbar 3 substantially absorbs all forces at the terminal point 5 and also has a sufficient large current conductivity due to their geometry.

  • the leaf spring 53 has a first spring leg 56, which is provided with a window-like recess 57. At the first spring leg 56 with the window-like recess 57, the clamping spring is arranged on the trough 9 as a busbar. Here it is placed on the open side of the trough 9 on the edges of the longitudinal legs 12, 13, wherein it is penetrated by the projection 40 of the busbar section 18, which is bent so that it the loop-shaped leaf spring 53 against removal from the trough secures in the region of the clamping point 55.
  • the leaf spring is aligned with the spring leg 56 parallel to the busbar and placed flat on the trough and / or attached thereto. Then, the leaf spring describes a closed loop 58, wherein it extends in the loop 58 outside the trough to the window-like recess 57 back and this with a free clamping leg 59 - which here only has the width of the recess - passes.

  • This leaf and clamping spring 53 thus surprisingly has a geometry which is reminiscent of the geometry of so-called tension spring connections. But it is arranged and designed so that a conductor from the opposite side of the loop 58 ago tool-free in the nip is inserted.
  • a very particular advantage of this clamping spring 53 in turn lies in the fact that on the one hand it allows a direct plug-in connection, because a conductor can be easily introduced into it but not easily pulled back against the edge in the region of the nip 55. For this purpose, the user rather needs a tool.
  • the clamping spring 53 itself absorbs all forces between the conductor end and clamping spring 53. It is only necessary that the spring leg 56 is fixed with the recess 57 on the busbar or the trough 9.
  • FIGS. 18 to 20 Another particularly advantageous embodiment of the invention is shown in FIGS. 18 to 20.
  • the terminal device shown in these figures has a bus bar 3, which is formed to the trough 9, in which the V-shaped leaf spring 4 is arranged.

  • the width of the leaf spring in the region of the bend substantially corresponds to the width of the trough 9, that is, in this area, the full available space is optimally utilized. This can be seen in particular from the installation situation of FIG. 20. Only in the region engaging in the trough, the leaf spring 4 then tapers in the region of its legs 6, 7 substantially to the inner width of the trough 9.
  • the width of the trough 9 corresponds substantially to the width of the leaf spring 4, so that this in the trough 9 fills the free U-shaped cross-section and extends from one longitudinal leg 12 to the other longitudinal leg 13. This in turn is the entire width of the clamping leg for inserting a conductor with a maximum of this width corresponding diameter available. On the side walls of the trough 9, the conductor can not dodge and is held securely.
