Slide contact probe for contacting on screws

The electrical contacting of screw threads is a worst case scenario for high current applications. Feinmetall has now developed a solution for this task that shows excellent results.

Slide principle

The new slide principle in the high-current probe HC07 combines the utility model protected scratch principle with round shaped silver heads. This means that the four spring-loaded contact probes are mounted inclined in the probe and thereby perform a slight lateral movement during the spring compression. As a result, the relatively soft silver slides over the thread and creates an optimum electrical contact without causing damage to the thread. The inclined position of the contact probes also ensures optimum adaptation to the contour of the screw.

Excellent results in real life tests

This solution has already been intensively tested and proven in practice. When contacting a thread profile of standard M8 screws at the side, the HC07 shows a temperature increase of only about 50° K at a continuous current of 70 A. An excellent result for these difficult contacting conditions.
