Long injector for fuel injection into an internal combustion engine

A fuel injection system of an internal combustion engine, the system comprising:

• a combustion chamber;
• and
• a long injector dosing fuel into the combustion chamber;
• wherein the long injector comprises:
• a base portion;
• an extension portion electrically connected to the base portion;
• and
• an encapsulation body molded over the base portion and the extension portion, wherein the base portion and the extension portion cannot be separated without destroying the encapsulation body;
• wherein a first end of the extension portion comprises an electrically conductive terminal with one or more contact clips;
• the one or more contact clips are spaced at a distance from each other or from a side wall of the electrically conductive terminal;
• a first end of the base portion comprises one or more electrical contacts positioned at the first end of the base portion in such a way that each of the one or more electrical contacts can slide into a respective contact clip of the electrically conductive terminal when connecting the extension portion to the base portion;
• the electrically conductive terminal includes a latch mechanism;
• an electrical connection between the base portion and the extension portion is created when each of the one or more electrical contacts is inserted into the respective contact clip and held by the latch mechanism.

A vehicle comprising:

• a combustion chamber;
• a drive mechanism driven by combustion of fuel in the combustion chamber;
• and
• a long injector dosing fuel into the combustion chamber;
• wherein the long injector comprises:
• a base portion;
• an extension portion electrically connected to the base portion;
• and
• an encapsulation body molded over the base portion and the extension portion, wherein the base portion and the extension portion cannot be separated without destroying the encapsulation body;
• wherein a first end of the extension portion comprises an electrically conductive terminal with one or more contact clips;
• the one or more contact clips are spaced at a distance from each other or from a side wall of the electrically conductive terminal;
• a first end of the base portion comprises one or more electrical contacts positioned at the first end of the base portion in such a way that each of the one or more electrical contacts can slide into a respective contact clip of the electrically conductive terminal when connecting the extension portion to the base portion;
• the electrically conductive terminal includes a latch mechanism;
• an electrical connection between the base portion and the extension portion is created when each of the one or more electrical contacts is inserted into the respective contact clip and held by the latch mechanism.

A method for manufacturing a long injector for fuel injection into an internal combustion engine, the method comprising:

• providing an extension portion, wherein an end of the extension portion comprises an electrically conductive terminal with one or more contact clips, wherein the one or more contact clips are spaced at a distance from each other or from a side wall of the electrically conductive terminal;
• providing a base portion, wherein an end of the base portion comprises one or more electrical contacts, wherein each of the one or more electrical contacts is positioned in such a way, that each of the one or more electrical contacts can slide into a respective contact clip of the electrically conductive terminal when connecting the extension portion to the base portion;
• electrically connecting the extension portion to the base portion by inserting the one or more electrical contacts into the respective contact clip until each of the one or more electrical contacts is held by a latch mechanism of the electrically conductive terminal;
• and
• overmolding the electrical connection to produce an encapsulation body encapsulating the electrical connection between the base portion and the extension portion, wherein the base portion and the extension portion cannot be separated without destroying the encapsulation body.
