  • the flange region 61 is designed in the form of a plate and is accommodated with a transition fit or a play between the pliers jaw plates of the associated pliers jaw 12.
  • the flange region 61 has a through hole 63 which is oriented transversely to the crimping force acting on the die 3 and transversely to the swivel plane of the dies 3, 4 and thus the pliers jaws 12, 13.
  • a fastening screw or a fastening pin extends through the through hole 63 and is held in both end regions in the mentioned jaw plates of the associated jaw 12.
  • a step 65 can be present in a transition region 64 between the flange region 61 and the die region 62, without this being absolutely necessary.
  • a base body of the die 3 has two bores 66, 67 oriented parallel to one another, which are oriented vertically to the crimping force acting on the die 3 and vertically to the swivel plane of the dies 3, 4. Bearing elements 68, 69 are held in the bores 66, 67.
  • the bearing elements 68, 69 are preferably designed as pins or bolts which are accommodated in the bores 66, 67 with a precise fit.
  • the die area 62 protrudes from the pliers jaw plates in the direction of the other die and serves to form the die contour 70.
  • the die area 62 protrudes from the pliers jaw plates in the direction of the other die and serves to form the die contour 70.
  • the transmitter unit 53, 54 is arranged in the flange region 61, so that the transmitter units 53, 54 can be protected by the pliers jaw plates when the dies 3, 4 are mounted in the pressing tongs 5.
  • the recess 55, 56 is preferably located on the side of the flange region 61 facing away from the die region 62.
  • Fig. 4 shows another example of the integration of the transmission units 53, 54 in the dies 3, 4.
  • the transmission units 53, 54 are also arranged here in the flange region 61 of the dies 3, 4.
  • the recesses 55, 56, here blind hole bores 57, 58 are arranged with an extension in the pliers head plane, an extension direction of the recesses 55, 56 or the blind hole bores 57, 58 preferably being oriented parallel to the pressing force.
  • the pressing tongs 5 preferably form a cavity in the region of an axis predetermined by the joining direction 59, in particular between the jaw plates, which ensures good signal transmission.
  • the marking processing unit 20 or the detection device 21 can then directly adjoin this cavity or further components or material areas can be arranged between the cavity and the detection device 21.
  • a recess or an interior of a die 3, 4, in which the transmission unit 53, 54 is arranged can be closed by a cover.
  • the flange region 61 or even the entire die 3 can be formed with two half-shells which form the interior for receiving the transmission unit 53, 54, the two half-shells being integrally connected to one another, for example by gluing or welding, and sealing the interior could be.
  • the distance of a transmission unit 53, 54 from an associated detection device 21 is preferably less than 3 cm, less than 2 cm, less than 1.5 cm or even less than 1 cm, this distance being at least partially due to the previously explained cavity of the pressing tongs 5 extends, which ensures good signal transmission.
  • the identification 18, 19 or the transmission unit 53, 54 has an RFID, the corresponding applies to an excitation signal for an energy supply of the RFID emitted by the identification processing unit 20.
