Publication number: 20140239937Abstract: A connector system includes a first connector having a plurality of first contact terminals, and a second connector having a plurality of second contact terminals. The second contact terminals are arranged such that, while connecting, the first contact terminals come into contact with a first subset of the plurality of second contact terminals in a first connecting stage. As the connection proceeds further the first contact terminals come into contact with a second subset of the second contact terminals. In the first connecting stage an electrical quantity between two of the first contact terminals is detectable. This electrical quantity is different from an electrical quantity in an uncoupled condition of the connectors. In the second connecting stage a further electrical quantity between at least two of the first contact terminals is detectable and different from the electrical quantity detected in the first connecting stage.Type: ApplicationFiled: December 2, 2013Publication date: August 28, 2014Applicant: Edwards Lifesciences IPRM AGInventors: Ulrich Pfeiffer, Reinhold Knoll, Tobias Thomamuller
