An electrical feedthrough comprising:
- a base body with a sealing region, at least one opening and an electrical conductor fed through the opening, the electrical conductor being held in the opening by a fixing material and the fixing material sealing the opening, edges surrounding the opening being designed to be sharp, all edges of an outer contour of the base body being provided with a chamfer or a rounding having a size or a radius r in the range of 0.3 mm to 2 mm.
A method for producing an electrical feedthrough, the method comprising:
- forming a base body with at least one opening from a blank, edges surrounding the opening being designed to be sharp and edges of an outer contour of the base body being provided with a chamfer or a rounding having a radius r in the range of 0.3 mm to 2 mm;
- inserting a fixing material blank and a conductor into at least one of the openings;
- and
- carrying out a heat treatment to form the fixing material from the fixing material blank.
