1. A lead feedthrough of an electrical functional unit that implements a capacitor or medical electronic implant, wherein said lead feedthrough comprises: a hollow conductive flange having a cavity, a flange end face, a flange flat tab and a flange body;a contact piece disposed in the cavity of said hollow conductive flange wherein the contact piece is electrically insulated and sealed with respect to the hollow conductive flange, and wherein said contact piece protrudes away from said hollow conductive flange;wherein the hollow conductive flange is configured to connect to a lead of a first type, and wherein the contact piece is configured to be connected to a lead of a second type in the electrical functional unit;wherein a circumferential section of the hollow conductive flange comprises a tangentially extending gap, which is delimited on one side by the flange body and on another side by a tab that extends at a distance from the flange body and is integrally formed on the flange body, or by a separate pressure piece, wherein said tangentially extending gap is configured to enable tangential insertion and affixation of the lead of the first type; and, wherein said tangentially extending gap comprises at least three open sides and enables said lead of the first type to be inserted and affixed orthogonal to said contact piece in at least one open side of said at least three open sides. 2. The lead feedthrough according to claim 1, wherein the tangentially extending gap configured to enable tangential insertion and affixation is configured to affix to one or several leads of the first type wherein said one or several leads of said first type are configured as sheet or film having a flat cuboid shape. 3. The lead feedthrough according to claim 2, wherein the tab or the separate pressure piece is configured in a flat prismatic shape, or shape of a flat cube or a flat trapezoid. 4. The lead feedthrough according to claim 1, wherein the tangentially extending gap configured to enable said tangential insertion and affixation is configured to affix one or several leads of the first type wherein said one or several leads of said first type are configured as sheet or film has the shape of a flat annular segment. 5. The lead feedthrough according to claim 4, wherein the tab or the separate pressure piece comprises a hollow-cylindrical section. 6. The lead feedthrough according to claim 1, wherein the hollow conductive flange comprises an end face which extends past a remaining circumference thereof and past a maximum radial extension of the tab or the separate pressure piece. 7. The lead feedthrough according to claim 1, further comprising a plug of injectable plastic and wherein the cavity of the flange comprises said plug of injectable plastic. 8. An electrical functional unit configured as a capacitor or medical electronic implant, and comprises a lead feedthrough, wherein said lead feedthrough comprises: a hollow conductive flange having a cavity and a flange body;a contact piece disposed in the cavity of said hollow conductive flange wherein the contact piece is electrically insulated and sealed with respect to the hollow conductive flange, and wherein said contact piece protrudes away from said hollow conductive flange;wherein the hollow conductive flange is configured to connect to a lead or leads of a first type, and the contact piece is configured to be connected to a lead of a second type in the electrical functional unit;wherein a circumferential section of the hollow conductive flange comprises a tangentially extending gap, which is delimited on one side by a flange body and on another side by a tab that extends at a distance from the flange body and is integrally formed on the flange body, or by a separate pressure piece, wherein said tangentially extending gap is configured to enable tangential insertion and affixation of the lead of the first type;wherein the lead or leads of the first type is or are welded to the hollow conductive flange in or on the tangentially extending gap; and, wherein said tangentially extending gap comprises at least three open sides and enables said lead of the first type to be inserted and affixed orthogonal to said contact piece in at least one open side of said at least three open sides. 9. The electrical functional unit according to claim 8, wherein a large number of leads of the first type, which are configured as cathode lugs, are coupled one on top of the other in the tangentially extending gap and are welded to one another or are welded to the hollow conductive flange or are welded to one another and to the hollow conductive flange. 10. The electrical functional unit according to claim 8 wherein the lead or leads of the first type are configured to be inserted into the tangentially extending gap and are configured to be cold-welded through pressure between the tab or the contact piece and the body of the hollow conductive flange. 11. The electrical functional unit according to claim 8 wherein the lead or leads of the first type are configured to be inserted into the tangentially extending gap, and free ends thereof are configured to be connected by laser welding. 12. The electrical functional unit according to claim 11, wherein said separate pressure piece is configured to be held in an intended position relative to the body of the hollow conductive flange by vacuum during insertion of the lead or leads. 13. The electrical functional unit according to claim 10, further comprising a plastic plug configured to be injection molded in the cavity of the hollow conductive flange and wherein the hollow conductive flange and the contact piece are configured to be placed in an injection mold in an intended positional relationship to one another. 14. The lead feedthrough according to claim 1, wherein said flange flat tab comprises a flat planar bottom side and said flange body comprises a flat portion that parallels said flat planar bottom side of said flange flat tab that define said tangentially extending gap, such that said tangentially extending gap defines two planes. 15. The lead feedthrough according to claim 1, wherein said circumferential section of the hollow conductive flange further comprises a second tangentially extending gap configured to ensure that a seal is heated to a lesser extent. 16. The electrical functional unit according to claim 8, wherein said hollow conductive flange further comprises a flange end face and a flange flat tab, wherein said flange flat tab comprises a flat planar bottom side and said flange body comprises a flat portion that parallels said flat planar bottom side of said flange flat tab that define said tangentially extending gap, such that said tangentially extending gap defines two planes. 17. The electrical functional unit according to claim 8, wherein said circumferential section of the hollow conductive flange further comprises a second tangentially extending gap configured to ensure that a seal is heated to a lesser extent.
