The fact that the sleeve-shaped base body is slotted due to the manufacturing process also means that a contact tab is provided under

There are three contact points on the inner conductor of the cable inserted into the contact.

An example of the innovation is shown in the drawing and is described in more detail in the following description under t. Bs «eigen:

The contact element 1 in the figures 1 to 3 has a sleeve-shaped contact body 2 which has a right-hand overseat. The contact body 2 extends into two arms 3 which face each other and form a gap which is approximately smaller than the circuit board with the corresponding contact pads.

(Fig. 4). The wheel frames have grooves which contribute to improving the contact. As can be seen from Fig. 3a and 3b, the springs 3 are provided with cuts 5, whereby each spring 3 is divided into two parts. This improves the firing effect of the springs and makes it possible to have a larger number of contact points.

On the outer body 2, there are provided point-like projections 10 which are spaced apart by a distance corresponding to the thickness of the circuit board. These projections 10 serve to guide the contact point on the circuit board. In an alternative embodiment (Fig. 3b) of the outer body 2, it has four contact tabs 7, the inner surfaces 94 9a of which are arranged axially one behind the other in pairs.

The contact element is bent from rolled sheet metal, whereby a longitudinal slot 11 is present. This longitudinal slot divides a contact tab 7 in the middle, so that two partial tabs 12 are formed. This measure improves the
