Abstract: A contact force testing apparatus includes a measuring sensor that can be contacted with an electrical contact element and measures a contact force (F) of a contact with the electrical contact element. The measuring sensor includes piezoelectric material that receives the contact force (F) in a contact region and produces polarization charges. The measuring sensor includes an acceptor electrode that is completely surrounded by piezoelectric material in the contact region in the direction of a thickness extension of the measuring sensor and receives the polarization charges. A method is provided for the use of such a contact force testing apparatus, and a method is provided for producing such a contact force testing apparatus.

Abstract: A contact force testing apparatus includes a measuring sensor that can be contacted with an electrical contact element and measures a contact force (F) of a contact with the electrical contact element of an electrical connector having a male component and a female component. The measuring sensor receives the contact force in a contact region with a piezoelectric pick-up. The measuring sensor includes a plurality of piezoelectric pick-ups that are spaced apart from one another by pick-up gaps. The measuring sensor has a protective sleeve that covers the piezoelectric pick-ups and the pick-up gaps in the contact region.
