  • the partition 10 extends between the material projections of the partition receptacle 11, which also facilitates the positioning and fixing of the first housing part 5A and the second housing part 5B to one another.
  • a symmetrical structure of the conductor connection terminal 1 is also clearly visible, with a symmetry axis (not shown) running perpendicular to the insertion direction R EF through the partition 10.
  • the conductor connection terminal 1 has a simplified design 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 direction R LE of the contact insert 2 is marked by a double arrow.
  • the contact insert 2 is inserted into the first housing part 5A transversely to this longitudinal extension direction R LE in an insertion direction R ES .
  • Figure 8 shows a perspective rear view of the conductor connection terminal 1 with the 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 latched, caulked and/or welded to one another 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 assembled from 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 accommodate the U-legs 9A of the first housing part 5A between them and the U-legs 9A of the first housing part 5A accommodate 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 view.
  • Figure 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 3 and an upper side Ko opposite the lower side Ku.
  • the contact insert 2 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 interchanged if the contact insert 2 is symmetrical.
  • the lower side Ku, the upper side Ko, the cover side K D and the housing side K G of the contact insert 2 can be regarded as longitudinal sides of the contact insert 2.
  • the contact insert 2 has a longitudinal extension in a longitudinal extension direction R LE that 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 transversely to its longitudinal direction of extension into a first housing part 5A.
  • the contact insert 2 can be pre-assembled or can be joined in an upstream preparation step from the busbar 3 and the clamping spring 4 or the clamping springs 4.
  • the housing part 5B which has a plurality of housing walls, is arranged, for example placed, on the first housing part 5A.
  • the direction in which the second housing part 5B is placed on the first housing part 5A corresponds in particular to the direction in which the contact insert 2 is inserted into the first housing part 5A.
  • the first housing part 5A is connected to the second housing part 5B, for example by locking, caulking or welding.
