- the undercut By means of the undercut, the tool can be reliably connected to the cutting clamp via the holding means. Due to this connection, actuation forces to be applied for producing the clamping connection essentially occur exclusively between the actuation tool according to the invention and the insulation displacement clamp according to the invention, so that no forces act on the support material during the connection process, or at most very little.
- the contact elements with the undercut are trapezoidal.
- the trapezoidal shape of the contact elements supports the self-locking of the holding means of the tool according to the invention to the contact elements.
- the holding elements are pressed by means of the trapezoidal and thus widening in the conductor insertion direction contact elements to the outside until they reach the undercut. After reaching the undercut, the holding means lock by engaging behind the undercut automatically the
