Various embodiments may include a long injector for fuel injection comprising: a base portion and an extension portion electrically connected to the base portion. An end of the extension portion may include an electrically conductive terminal with contact clips. The contact clips are spaced at a distance from each other or from a side wall of the electrically conductive terminal. An end of the base portion comprises electrical contacts positioned so each of the electrical contacts can slide into a contact clip of the electrically conductive terminal. The electrically conductive terminal includes a latch mechanism. An electrical connection between the base portion and the extension portion is created when the electrical contacts are inserted into the contact clip and held by the latch mechanism. The long injector further comprises an overmolded body encapsulating the electrical connection between the base portion and the extension portion.
