The present invention relates to a HVIL system for a HV connector, in particular in a motor vehicle, which HV connector is configured to transmit HV current from the HV connector to a further component, wherein the HVIL system has a first HVIL contact element and a second HVIL contact element, wherein, in a non-plugged state of the HV connector, the first HVIL contact element is spaced apart from the second HVIL contact element by at least one first spring element; and wherein, in a plugged state of the HV connector, the first spring element is deformed in such a way that the first HVIL contact element makes contact with the second HVIL contact element in such a way that the HVIL system ensures that HV current is transmitted from the HV connector to the further component if the connection between the HV connector and the further component is secure. The present invention furthermore relates to a method for establishing a HV connection.
