Abstract
A lead feedthrough of an electrical functional unit, in particular a capacitor or medical electronic implant, which comprises a hollow conductive flange and a contact piece disposed in the cavity thereof and which is electrically insulated and sealed with respect to the flange, wherein the flange can be connected to a lead of a first type, and the contact piece can be connected to a lead of a second type in the functional unit, wherein, in a circumferential section of the flange, a tangentially extending gap is provided, which is delimited on one side by a flange body and on the other side by a tab integrally formed on the body, or by a separate pressure piece, for the tangential insertion and affixation of the lead of the first type.
Claims17
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.
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.
