  • a spring clamp 42-i is provided with a mechanical drive 8-i for actuating the spring clamp 42-i to move it to an open position in which an electrical conductor 51 in the insertion opening 50 of the spring clamp 42-i insertable is and a closed position in which an inserted in the insertion opening 50 electrical conductor 51 is clamped in the spring-type terminal.
  • a spring-loaded terminal in this case, in particular, a conventional spring-loaded terminal can be used and actuated by means of the mechanical drive 8-i.
  • a mechanical drive 8-i provided for actuating the spring-type terminal 42-i and in particular also of conventional spring-type terminals.
