- the avoidance of vibratory grinding particles ensures that imperfections in the surface of the connecting pin are suppressed and / or avoided.
- the advantage of surfaces without or largely free of defects is that there are no defects in coatings, for example nickel and / or gold coatings applied to the pin. If the surface is largely free of imperfections, it is easier to apply a closed surface coating.

- a connecting pin is particularly preferably designed in such a way that, in the case of a pin with a diameter of 1 mm, the rounded section of the end region opens after 0.65 mm into the cylindrical section with a diameter D. In contrast to this, in the case of a connecting pin or pin rounded with slide grinding particles and having a diameter of 1 mm, the cylindrical part with the predetermined diameter D is only reached after more than 0.7 mm.
- the advantage of rounding or introducing the radius using a non-cutting or non-cutting method according to the invention is that the radii can be produced according to a specified specification, which enable a shortened transition area to the cylindrical area of the connecting pin.
- the profile of a polished pin always shows a barrel shape, i.e. the transition from the radius to the cylindrical pin has a longer course that goes beyond the radius. That can be a disadvantage for the
- the shape of the connecting pin is a cylindrical shape with a diameter D of, for example, 1 mm.
- D diameter of, for example, 1 mm.
- the connecting pin with the cylindrical shape goes into a rounded area, ideally a hemispherical one Cap with a radius R above.

- End sections 10.1, 10.2 of the pin 1 are rounded according to the invention, specifically with the aid of a non-cutting and / or cutting method, the radius R of the rounding being predetermined.
- the radius R can be, for example, 0.5 mm, the diameter D of the connecting pin 1 mm.
- connection pins are obtained by cutting from a wire section.
- the not straight, ie bent section 5 of the pin is 45 ° with respect to the straight area 3 and the end section 7 inclined.
- the diameter D of the pin is, for example, between 0.5 and 2.5 mm. Pins with a diameter smaller than 0.5 mm are also possible.
- FIG. 2 shows the end section with rounding.
- the rounding or the rounding section which in the ideal case is conical but does not have to be, comprises a radius R.
- the radius is in the range 0.25 mm to 1.0 mm.
- the rounding section has a side length that is also in the region of the radius, i. H. between 0.25 mm and 1.0 mm.
- the height of the rounding up to the transition into the cylindrical region can be 0.5 mm.
- the diameter of the pin is then at about 1.0 mm.
- a nickel layer is first applied to the connection pin as corrosion protection. After the nickel coating, a gold layer is applied.
- the thickness of the nickel and gold coating is in the pm range, preferably in the range 0.1 pm to 10 pm.
- a coating with palladium can also be carried out. Thanks to the coating with nickel and gold, a contact-safe plug connection with low contact resistance becomes
- the coating for example made of nickel, applied to the connecting pin has no defects, which leads to the fact that the Terminal pin remains largely corrosion-free.
- free or largely free of impurities is understood to mean that less than 2%, in particular less than 1.5%, preferably less than 1%, very preferably less than 0.5%, particularly preferably less than 0.1% the pen surface are contaminated, e.g. with vibratory abrasive particles.
- Undesired slide grinding particles are especially particles a ceramic material, such as Al 2 O 3 or SiC.
- Particles made of other materials are less damaging with regard to defects and are therefore tolerable. This leads to a low contact resistance.
- the absence of a vibratory abrasive prevents defects, which in turn lead to corrosion and, due to the corrosion, lead to the contact resistance increasing and ultimately a power line being lost over time.
- FIG. 3 shows the use of a connecting pin according to the invention, in particular a metal pin, in a bushing.
- FIG. 3 shows a feedthrough 100, in particular a metal fixing material feedthrough for devices which are exposed to high pressures.

- Both the connecting pin, in particular metal pin 50, and the connecting pin, in particular metal pin 52, are designed to be curved. The arc of both metal pins is labeled 54 and 56 and clearly recognizable.

- Fixing material 60 takes place by melting. As soon as the connecting pin, in particular the metal pin, has melted into the fixing material 60, the glass plug is introduced into the through opening 20 together with the metal pin. Then the glass plug together with the ring or plate-shaped element, i.e. the base body, heated so that after cooling the metal of the ring or plate-shaped element on the

- connection pins in particular metal pins, so that the connection pins can be provided with a coating without defects.
- the coated pins have a low contact resistance. Since defects are avoided, subsequent coating with Ni or Au, for example, with a closed surface is largely free of defects. The closed surface in turn ensures that corrosion can be largely ruled out.
- 4a and 4b show rounded pins produced using the method according to the invention and rounded pins produced with the aid of slide grinding particles.
- FIG. 4a shows a connector pin produced according to the invention in accordance with a specified specification.
- the connecting pin produced according to FIG. 4a is a connecting pin in which the cap 110 was produced using cold forming.
- the section of the rounding section corresponds geometrically to a segment of a circle, the diameter D of the
- cylindrical part of the pin is 1 mm.
- the diameter of the end face F is 0.1 mm.
- the radius R would be identical to half the diameter D of the cylindrical part 120 of the pin 1, ie 0.5 mm.
- the range 0.4 ⁇ R ⁇ 0.65D for the radius can, however, still be regarded as in accordance with the invention.
- Another preferred embodiment corresponds to the formula
- the invention makes it particularly advantageous that the diameter of the end face F can be less than 0.4 mm, in particular less than 0.3 mm.
- the cold-formed connecting pin shows a rounding of the end section with a predetermined radius R and a cap with round segment-shaped rounding sections, this is not achieved, as shown in FIG. 4b, in the case of a connecting pin in which the rounding is produced by means of slide grinding particles.
- the rounding section is in particular
- connection area of the pin is with the reference number 1100 designated.
- the cylindrical part of the connector pin has one
- Diameter D 1 mm.
- the profile of the pin is barrel-shaped, i.e. the transition from the connection area 1100 to the cylindrical part is 0.9 mm in contrast to 0.65 mm according to FIG. As a result, a much higher one
