Abstract

Une borne à ajustement par pression (10) est insérée dans un trou traversant (23) disposé sur une carte de circuit imprimé (20). La borne à ajustement par pression comprend une partie base (11) s'étendant dans une direction d'insertion de la borne à ajustement par pression (10) ; une partie ajustement par pression (13) disposée davantage vers un côté de pointe dans la direction d'insertion que la partie base (11) ; et une partie épaulement (14) disposée sur le côté opposé dans la direction d'insertion par rapport à la partie ajustement par pression (13). La partie ajustement par pression (13) comprend une paire de parties contact élastiques (15), et une fente (16) formée en étant entourée par la paire de parties contact élastiques (15). Chaque partie contact de la paire de parties contact élastiques (15) est conçue pour être élastiquement déformable par mise en contact avec une paroi interne du trou traversant (23). La fente (16) est ouverte dans la direction de l'épaisseur de la partie base (11) orthogonale à la fois à la direction d'insertion et à la direction de la largeur de la partie base (11). La partie épaulement (14) fait saillie depuis la partie base (11) dans une direction croisant la direction d'insertion et croisant également la direction de la largeur de la partie base (11).
