  • Housing 1 has between opening 11 for receiving the flat film conductor 12 and the Fastening area 6 on a transition area 14, which in Cross-section, as can be seen better in Figure 7, a double-T-shaped Has profile. Because of the double T-shaped Profile is achieved with the smallest possible The highest possible force can be taken over by the material can. This is necessary if the flat film conductor 12 for Contacting of contacts 2 is pressed into opening 11 becomes.
  • a multiplicity of contacts 2 are arranged in the housing 1 arranged in parallel next to each other.
  • the contacts 2 are at least in a partial area 15 in parallel grooves or channels 16 added.
  • the walls of the channels 16 limit the lateral movement of the sections 15 in the movement of the freely movable second ends 4.
  • a press block 17 is located above the opening 11 arranged.
  • the press block 17 is in the opening 11 of the Housing 1 perpendicular to the direction of the ladder applicable.
  • the Press block 17 has a length that is essentially equal to the width of the flat film conductor 12 corresponds and has a cross section which is essentially the same as that of Depth and width of the opening 11 of the housing 1 matches.
  • both the press block 17 and the transition area also represent 14 large areas, which are advantageous for automated assembly.
  • Lots Automatic assembly machines work with so-called vacuum tweezers, who can vacuum large areas with vacuum and so on Can move and assemble individual parts.
  • FIG 1 it can also be seen how the housing 1 both sides of the mounting area 9 has cams 18 which engage in recesses 19 of the flat film conductor 12.
