  • the invention further relates to a crimping device which comprises a feed device and a table.
  • Crimping devices are known in the prior art that have a feed device for moving a contact element strip in the direction of a crimping die.
  • the feed device comprises a feed element that is held by a feed element holder.
  • the feed element pushes the contact element strip step by step in the direction of the crimping die, where a contact element of the contact element strip is applied to an electrical conductor.
  • the feed device is designed for a translatory movement, whereby a feed movement pushes the contact element strip forward to the crimping die on This occurs because the feed element engages in an opening on the contact element strip and when the feed device moves back, the feed element can be pivoted about a horizontal axis in order to be moved out of the opening on the contact element strip by a pivoting movement.
  • the feed element is guided to a secondary opening on the contact element strip and can push the contact element strip in the direction of the crimping die during a further feed movement.
  • a crimping tool is described with a base body comprising a pressing device and a clamp assigned to the base body for guiding the crimp contacts.
  • the aim of the invention is to provide a feed device and a crimping device which is characterized by increased user-friendliness.
