  • a second position S2 as in FIG. 2 shown, the slider 20 is detached from the housing wall 10.
  • This disengagement of the slider 20 has the consequence that in the second position S2, the actuating means 21, the contact spring 5a releases, so that a clamping action between the contact spring 5a and the electrically conductive end 2a prevails.
  • the contact spring 5a now presses with a spring force on the electrically conductive end 2a, whereby a secure contact is given.
  • the contact spring 5 a is electrically conductively connected to the respective clamping body 5.

  • FIG. 7 illustrates again in a perspective sectional view, the interaction between the drive means 22 and the slider 20. Due to the fact that during rotation of the drive means 22, the cam 23 slides in the cam receiver 24, the slider 20 slides in the direction of the housing wall 10, whereby the actuating means 21 the Deflect contact springs 5a.
  • FIG. 8 shows a further perspective view, wherein the housing wall 10 has a longitudinally extending groove 31 and the circuit board 1 is disposed in the groove 31.
  • An insertable from the other side receiving body 3 can now be plugged with its fixed electrical leads 2 in the respective recesses.
  • this connector system with clamping springs 5a As a major advantage of this connector system with clamping springs 5a is considered that due to the multiply loaded receiving body 3 and the slider 20 with the simultaneous operation of the contact springs 5a by the actuating means 21, it is possible to have a plurality of electrical lines 2 with their electrically conductive To clamp ends 2a with the contact springs 5a.
