Publication number: 20140194015Abstract: The invention relates to a method for improving the transition resistance in an electrical connection, in particular a pressure connection, between two contact elements. With repeated mechanical or thermal loads, such connections, in particular connections having a small cross-section or comprising soft material, have a transition resistance which increases over time. According to the invention, the transition resistance is improved by there being applied to at least one contact face of a contact element a chemically reducing substance which activates the contact face and consequently increases the conductivity and the cold welding density.Type: ApplicationFiled: August 6, 2012Publication date: July 10, 2014Applicant: TYCO ELECTRONICS AMP GMBHInventors: Helge Schmidt, Uwe Bluemmel
