Abstract

An electrical connector part for transmitting a charging current has at least two contact elements for producing an electrical contact having associated contact elements of another electrical connector part, a support element on which the at least two contact elements are disposed, and a resistance device which is electrically connected to the at least two contact elements. The resistance device has a circuit board, an electrical resistor disposed on the circuit board, and at least one contact spring disposed on the circuit board and electrically connected to the resistance, the circuit board being retained on the support element and the at least one contact spring electrically contacts one of the at least two contact elements. Thus, an electrical connector part can be created which in a simple manner enables the integration of a resistance device into an electrical connector part for the purpose of a resistance coding to provide identification information to an electrical plug to be mated to the electrical connector part.
