Gastight electrical bushing and its use in a projectile

A method for producing a gastight electrical bushing for a projectile having a tail section a propellant charge primer, and a gastight electrical bushing for transmitting electric signals from a high-pressure region to a low-pressure region, the bushing including a base body having an insulated outer body and a metallic, electrically conducting inner conductor, wherein the metallic base body forms a ground wire, and only a signal line, which is insulated inside the base body, is passed through a bore in the base body, wherein the signal line essentially fills the bore, wherein the base body is formed by the tail section, wherein the propellant charge primer is directly connected with the tail section so that the propellant charge primer can be mounted from behind on the tail section, and direct contact between the propellant charge primer and the tail section is realized, the method comprising the steps of:

• introducing the bore into the base body so as to connect a front end and a rear end of the base body;
• introducing receiving areas into the front end and the rear end to receive connecting contacts;
• subsequently coating the entire base body with an electrically insulating material;
• introducing coating-free blind bores into the base body from the front end and/or the rear end to provide contact of the base body used as the ground wire;
• inserting an electrically conducting signal line that substantially fills the bore into the bore;
• and
• electrically conductively connecting the signal line with the connecting contacts inserted in the receiving areas.
