Prechamber spark plug for a gas-powered internal combustion engine, and method for manufacturing same

A prechamber spark plug for a gas-powered internal combustion engine, comprising:

• a metallic body, a front end, and an external thread located at the front end for screwing the prechamber spark plug into the internal combustion engine;
• the metallic body has a passage in which an insulator is mounted that surrounds a center conductor, which is connected in an electrically conductive manner to a center electrode projecting out of the insulator at the front end;
• at least one ground electrode is connected in an electrically conductive manner to the body, and forms a spark air gap with the center electrode;
• arranged at the front end is a cap that shields the center electrode and the ground electrode from a combustion chamber of the internal combustion engine after the prechamber spark plug is installed in the internal combustion engine, and that delimits a prechamber in which the center electrode and the ground electrode are located from the combustion chamber;
• and
• the cap has at least one opening that permits gas exchange between the prechamber and the space outside of the prechamber;
• wherein the cap is mounted on a sleeve surrounding a section of the body, and the sleeve contains the external thread for screwing into the internal combustion engine and is joined to the body.
