Abstract
The disclosure relates to a connector pin, in particular a metal pin, for feedthroughs, in particular glass-metal feedthroughs, with at least one first, elongated portion, as well as at least one adjoining end portion, and the end portion has a rounding with at least radius R. The disclosure is further characterized in that the cone and/or radius R is preferably a cone and/or radius according to a specification and is obtained by means of a material-removing method and/or a non-material-removing method.
Claims17
A connector pin for a feedthrough, comprising:
- an elongated, cylindrical portion extending along a pin axis thereof and having a diameter D;
- an adjoining end portion that has a circular face F essentially perpendicular to the pin axis;
- and
- a fillet and/or a fillet portion with a radius R connecting the cylindrical portion to the circular face F about an entire circumference of the circular face F,
- wherein the circular face F has a flat surface with a diameter of less than 0.1 mm,
- wherein the radius R of the fillet and/or of the fillet portion is in a range of 0.4·D to 0.65·D, and wherein the radius R is obtained with a material-removing method and/or a non-material-removing method.
