In all, the unit is equipped with nine sets of blades (31), consisting of one blade (31) above and another below. Blades (31) are mounted on aluminium blocks (32) attached to two pneumatic linear actuators disposed so that there is one above and one below. In their initial position these actuators are open, so that transport system (6) can place the wire to be stripped between appropriate blades (31) depending on the cross-section.
  • the pneumatic linear actuators When the wire is in place, the pneumatic linear actuators are activated, closing blades (31) on the wire, leaving just the central core in the space between blades (31), such that when the unit withdraws the wire, the insulation is retained between blades (31) and the wire is stripped.
  • the unit also has a pair of blades (31) that severs the wires completely; this cut is made before stripping the wire so that all the wires will have the same cut across the end.
  • This unit has been designed to crimp up to 15 different types of terminal.
  • the modular nature of the invention allows the number of terminals to be expanded, including exchangeability for different terminal types according to need.
  • the module has two different crimping clamps, the crimping jaws of each adapted to the terminal crimping tools used according to standards MIL-C-22520-1 and MIL-C-22520-2.
