本発明に従えば、コンタクトバンプは、突出縁部を有するとともに、変位コンパートメント内に少なくとも1つの変位ピンを有し、変位コンパートメントは、突出縁部に囲まれ、コンタクトバンプのヘッド端部に向けて開放され、この変位ピンは、突出縁部によって径方向の外側で限定された変位コンパートメントと組み合わせて、既に上で詳細に説明された利点を有する。
本発明に従えば、端面の機械的な接続を作るために、第1端面に配置されたコンタクトバンプが第2端面の接触材料の接触面に圧入され、コンタクトバンプの変位コンパートメントにおいて、突出縁部および変位ピンが第2端面の接触材料内に入り込む一方、圧入方向に対し、前記接触材料が径方向内側へ向けた突出縁部の圧力および径方向外側へ向けた変位ピンの圧力の両方に晒され、上で既に詳しく説明したように、接触材料が、突出縁部によって径方向外側で変位コンパートメントを限定する壁面および変位ピンによって径方向内側で変位コンパートメントを限定する壁面に対し、径方向にしっかりと嵌めこまれる、またはこれに入り込む。
