An electrical connector includes a blade terminal configured to establish an electrical circuit. The electrical connector also includes a receiving terminal coupled to the blade terminal. The receiving terminal includes a bridge portion, a first leg extending from the bridge portion, and a second leg extending from the bridge portion and separated from the first leg by a slot defined by the bridge portion, the first leg, and the second leg. Moreover, at least one of the first leg and the second leg include a geometric feature extending into the slot such that the slot is configured to prevent insertion of a second electrical connector into the slot.
