Abstract
In a method for the determination of an electrical contact property in a contact region between a first contact element of a first plug device and a second complementary contact element of a second plug device, a property of a current path including the first contact element, the contact region, and from the second plug device only the second contact element is evaluated and an induction voltage is generated in the current path for a measurement in the current path to thereby enable to draw a conclusion about the electrical contact property.

A method for the determination of an electrical contact property in a contact region between a first contact element of a first plug device and a second complementary contact element of a second plug device, said method comprising:
- evaluating a property of a current path which includes the first contact element, the contact region, and from the second plug device only the second contact element;
- and
- generating an induction voltage in the current path for a measurement in the current path to thereby enable to draw a conclusion about the electrical contact property.
A method for the determination of an electrical contact property in a contact region between a first contact element of a first plug device and a second complementary contact element of a second plug device, said method comprising:
- evaluating a property of a current path which includes the first contact element, the contact region, and from the second plug device only the second contact element;
- and
- adding in the current path at least two sensors which are arranged in the first plug device and contact the second contact element when the first and second contact elements are plugged together.
A method for the determination of an electrical contact property in a contact region between a first contact element of a first plug device and a second complementary contact element of a second plug device, said method comprising:
- evaluating a property of a current path which includes the first contact element, the contact region, and from the second plug device only the second contact element;
- and
- synchronizing the evaluation of the property of the current path with a course of an operating current across the contact region.
A method for the determination of an electrical contact property in a contact region between a first contact element of a first plug device and a second complementary contact element of a second plug device, said method comprising:
- evaluating a property of a current path which includes the first contact element, the contact region, and from the second plug device only the second contact element;
- disposing in the current path a sensor which is arranged in the first plug device and contacts the second contact element when the first and second contact elements are plugged together;
- and
- forming in the current path a capacitance of more than about 10 pF to allow an alternating current flow in the current path.
A plug device, comprising:
- a first plug device including a first contact element;
- a second plug device including a second contact element which complements the first contact element and contacts the first contact element, when the first and second contact elements are plugged together in a contact region;
- a current path including the first contact element, the contact region, and from the second plug device only the second contact element;
- and
- means for generating an induction voltage in the current path for a measurement in the current path to thereby enable to draw a conclusion about an electrical contact property in a contact region between the first contact element and the second contact element.
A plug device, comprising:
- a first plug device including a first contact element;
- a second plug device including a second contact element which complements the first contact element and contacts the first contact element, when the first and second contact elements are plugged together in a contact region;
- a current path including the first contact element, the contact region, and from the second plug device only the second contact element;
- and
- at least two sensors configured to contact the second contact element when the first and second contact elements are plugged together.
