In the world history of the innovation, such a contagion where the fastening nut

Sound is surrounded by a shielding electrode, this shielding electrode arranged in a torsion-free manner opposite the contact arrangement and on the inside facing the nut Provided with incisions in the subdivision, such as "da * a web from the inside of the shielding electrode can be pushed out and in a slot as a locknut trained cutter is legible.

The Tortelle obtained with the innovation consist in particular of the following!

As a result, the connection bolts and overrun contact approximately smoothly dlek are «results in Aryan at the crossing point inter alia an overrun contact for the field

Run favorable curvature of the surface. As a result of oval shape of the approach contact succeeds in the touch point move further away from the support rod with the contact bridge opposite a circular run-up contact » without the need for a separate support rod and contact with a special extension piece muA. The roughly hemispherical rounding on the indices of the Auflaufkiintaktes is in turn favorable for the course of the field, especially with regard to the arrangement of adjacent Atuflaufkojataktes · the usual Veis * in one Level above or below in a staggered arrangement are provided »and ultimately the intended forms The twisting effect caused by the engagement of the run-up contact in the groove of the support rod sustande kom & t, a simple · solution that reports sharp-edged parts «

Also securing the mother Dsl provided shielding electrode thanks to the bars that can be pushed out of the electrode, it is extremely easy. It can be assumed here that that as a result of the incisions being made on the

On the inside of the electrode when the nut is pulled up, there is always a 3teg generally the area of a groove in the nut kOBtfft.

An implementation of the innovation is in the drawing dargee shares üüi will ia following SfHe? Maantrieb. u • own

As can be seen from the drawing, the T-shaped contact piece, with its stem designed as a connecting bolt 1, is pierced through a hole in a support bar. The Anseh!

Further, the wrap contact 3 dad has in cross-section oval shape, the outer radius r ₁ KrUmmungi.-Etnas is selected to be larger than the the support rod 2 sugekehrte KrClmmungsradius r _£. In this way it is achieved that all of the Xonta cross-cut points have a greater spacing on the carrier groove 2 than would be possible in comparison with a small cross-section. The run-up contact 3 engages in a groove 8 of the support rod with its side resting on the support rod 2, in order to form a twist protection.
