It also becomes clear how the receiving structure 6 of the conductor connection terminal 1 with several structural elements such as spring supports, the partition wall holder 11, the frame walls 7 and the support blocks 12 define a delimited receiving space for the contact insert 2 so that it is held securely in the housing 5 and assembly is made easier.
  • partition wall 10 dips between the material projections of the partition wall holder 11, which also enables positioning and fixing of the first housing part 5A and the second housing part 5B to one another. is promoted.
  • a symmetrical structure of the conductor connection terminal 1 with a symmetry axis (not shown) running perpendicular to the insertion direction R EF through the partition 10 is also clearly visible.
  • the conductor connection terminal 1 has a simplified structure and enables easier assembly of the conductor connection terminal 1.
  • the receiving structure 6 of the first housing wall GW 1 of the first housing part 5A is easily accessible and enables quick and secure assembly of the contact insert 2 on the first housing part 5A.
  • the second housing part 5B can be safely and quickly arranged on the first housing part 5A and connected to it.
  • Figure 7 shows the representation of the conductor connection terminal 1 from Figure 6 for further illustration in a perspective view.
  • the longitudinal extension direction R LE of the contact insert 2 is marked by a double arrow.
  • Figure 8 shows a perspective rear view of the conductor connection terminal 1 with assembled housing 5. It can be seen that the housing parts 5A, 5B are assembled along a connecting line 15. At the connecting line 15, the first housing wall GW 1 of the first housing part 5A and the fourth housing wall GW 4 of the second housing part 5B merge flush into one another. The situation is similar on the opposite side at the transition from the first housing wall GW 1 to the third housing wall GW 3 .
  • the first housing part 5A and the second housing part 5B can, for example, also be locked, caulked and/or welded together in the assembled state of the housing 5.
  • Figure 9 shows a sectional side view of the conductor connection terminal 1 with inserted contact insert 2 and housing 5 composed of the housing parts 5A, 5B.
  • the first housing part 5A and the second housing part 5B in the embodiment shown each have a U-shaped cross-section, wherein in the assembled state of the housing 5 the U-legs 9B of the second housing part 5B receive the U-legs 9A of the first housing part 5A between them and the U-legs 9A of the first housing part 5A receive the contact insert 2 between them.
  • Figure 10 shows the sectioned view of the conductor connection terminal 1 from Figure 9 for additional illustration in a perspective representation.
  • FIG 11 shows a pre-assembled contact insert 2 for the conductor connection terminal 1 in a perspective view.
  • the contact insert 2 has a busbar 3, on each end of which a clamping spring 4 is placed to form a spring-loaded terminal connection with an electrical conductor.
  • the contact insert 2 has two end faces Ks, via which the respective electrical conductor is brought closer and inserted into the contact insert 2.
  • the contact insert 2 also has a bottom side Ku facing the busbar 3 and a top side Ko opposite the bottom side Ku.
  • the contact insert 2 also has a cover side K D facing the cover housing 5B and a housing side K G facing the base housing 5A, which can also be swapped if the contact insert 2 is designed symmetrically.
  • the bottom side Ku, the top side Ko, the cover side K D and the housing side K G of the contact insert 2 can be regarded as the long sides of the contact insert 2.
  • the contact insert 2 has a longitudinal extension in a longitudinal extension direction R LE which is parallel to an insertion direction of the electrical conductor.
  • Figure 12 shows a method for assembling a conductor connection terminal 1 from a contact insert 2, which has a busbar 3 and one or here two clamping springs 4, a first housing part 5A and a second housing part 5B.
  • a contact insert 2 is inserted into a first housing part 5A transversely to its longitudinal extension direction.
  • the contact insert 2 can be pre-assembled or can be assembled from the busbar 3 and the clamping spring 4 or the clamping springs 4 in a preceding preparation step.
  • the several housing walls The housing part 5B having a housing element 5A is arranged, for example placed, on the first housing part 5A.
  • the direction of placement of the second housing part 5B on the first housing part 5A corresponds in particular to the direction of insertion of the contact insert 2 into the first housing part 5A.
  • the first housing part 5A is connected to the second housing part 5B, for example locked, caulked or welded.
