Substrate for contacting at least one electrical pin of a charging inlet

An assembly, comprising:

• a housing accommodating an electrical pin and having a mating opening receiving a mating contact pin of a mating connector in a mating direction;
• and
• a substrate contacting the electrical pin arranged in the housing, the substrate including a base having a recess receiving the electrical pin, a metal leadframe having a contacting region electrically and/or thermally contacting the electrical pin, the metal leadframe is rigidly fixed to the base to prevent a relative movement between the metal leadframe and the base, and a contact pin extending along a mating direction in a plane parallel to the metal leadframe and configured to electrically contact the mating contact pin, the substrate is movable with respect to the housing along a locking direction from an unlocked position where the substrate is not locked to the housing to a locked position in which the substrate is locked to the housing, a movement of the contacting region with respect to the electrical pin is prevented in the locked position, the locking direction is perpendicular to the mating direction.
