Electrical connector has contact layer with rare metal on ceramic substrate, with thickness of contact layer being less than that of conductor, which has layers of different thickness and resistivity

摘要

The connector has a contact layer (2) containing a rare metal on a ceramic substrate (1), whereby the thickness of the contact film is less than that of the conductor. The conductor has at least two layers (3,4) of different thickness and different electrical specific resistance with the first layer (3) facing the contact layer having the lower specific resistance. The electrical connection between the conductor and the contact layer is made with gap welding Independent claims are also included for the following: a method of making an electrical connection and a use of the electrical connection for connecting a sensor in a vehicle.
