Contact force testing apparatus, use of such a contact force testing apparatus and method for producing such a contact force testing apparatus
First Claim
1. A testing apparatus for measuring a contact force applied by a female electrical contact element of a female electrical connector, which is configured for effecting electrical connection with a male electrical contact element, the apparatus comprising:
- a measuring sensor having a contact region configured for being disposed in contact with the female electrical contact element of the female electrical connector when the measuring sensor is inserted into the female electrical connector in place of the male electrical contact element, the measuring sensor including a plurality of piezoelectric pick-ups disposed in the contact region, each of the plurality of piezoelectric pick-ups including piezoelectric material;
each of the plurality of piezoelectric pick-ups being disposed-spaced apart from one another by a respective one of a plurality of pick-up gaps; and
a protective sleeve made of electrically conducting material that covers the plurality of piezoelectric pick-ups and the plurality of pick-up gaps in the contact region and wherein the protective sleeve is configured to be disposable between the female electrical contact element and the plurality of piezoelectric pick-ups when the measuring sensor is inserted into the female electrical connector.

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.
