Connection pin and a method for mounting a connection pin in a component carrier for an electronic assembly, and such a component carrier comprising connection pins

摘要

A connection pin for mounting in a through-hole of a component carrier, comprising an anchoring part adapted for insertion into said through-hole with a non press fit, a contact part adapted to extend outside said through-hole, and a flange part adapted to abut against said component carrier and located between said anchoring part and said contact part. The anchoring part is provided an internal cavity and the anchoring part comprises a wall surrounding the internal cavity, which wall has at least two wall portions forming deformation zones and adapted to be located in the through-hole when the anchoring part is inserted in the through-hole, such that, upon exertion of a force on a free end of the anchoring part of the pin when the anchoring part is inserted in the through-hole, the deformation zones are deformed within the through-hole to press fit the connection pin in the through-hole.

1. A connection pin for mounting in a through-hole provided in a component carrier, the connection pin comprising:
an anchoring part adapted for insertion into said through-hole with a non press fit, wherein the anchoring part has an internal cavity and that the anchoring part comprises a wall surrounding the internal cavity, which wall has at least two wall portions forming deformation zones and which wall portions are adapted to be located in the through-hole when the anchoring part is inserted in the through-hole; a contact part adapted to extend outside said through-hole; and a flange part adapted to abut against said component carrier and located between said anchoring part and said contact part, wherein the flange part has a contact side adapted for abutment against said component carrier, wherein the internal cavity has at least one inner opening, adjacent the flange part, wherein said contact side is provided with at least one groove communicating with said inner opening, and wherein the at least one groove stretches from the inner opening to a corresponding groove opening in an external axial surface of the flange part, wherein upon exertion of a force on a free end of the anchoring part of the pin when the anchoring part is inserted in the through-hole, the deformation zones are deformed within the through-hole to press fit the connection pin in the through-hole.
