Claim 1
Independent Claim
162 words
An electrical contact pin for insertion into a through hole in a printed circuit board, said through hole having inner walls, said electrical contact pin having a longitudinal axis, said electrical contact pin comprising: an insertion portion for guiding said electrical contact pin into said through hole; a cross rib integrally formed with said insertion portion, said cross rib defining longitudinal surfaces along said longitudinal axis; fin-like contacts extending from said longitudinal surfaces towards distal ends, each of said fin-like contacts having a contact surface and a curved portion, wherein each of said curved portions extends a distance along the entire length as well as a substantial portion beginning from said longitudinal surfaces towards said distal ends of said fin-like contacts and is curved inwardly towards the center of said longitudinal surfaces; and a guiding portion comprised of a leading portion of each of said fin-like contacts, said guiding portion having a guiding surface which is curved to define a gradual curvature.
Claim 2
Dependent Claim
162 words
An electrical contact pin for insertion into a through hole in a printed circuit board, said through hole having inner walls, said electrical contact pin having a longitudinal axis, said electrical contact pin comprising: an insertion portion for guiding said electrical contact pin into said through hole; a cross rib integrally formed with said insertion portion, said cross rib defining longitudinal surfaces along said longitudinal axis; fin-like contacts extending from said longitudinal surfaces towards distal ends, each of said fin-like contacts having a contact surface and a curved portion, wherein each of said curved portions extends a distance along the entire length as well as a substantial portion beginning from said longitudinal surfaces towards said distal ends of said fin-like contacts and is curved inwardly towards the center of said longitudinal surfaces; and a guiding portion comprised of a leading portion of each of said fin-like contacts, said guiding portion having a guiding surface which is curved to define a gradual curvature.
Claim 3
Dependent Claim
190 words
An electrical contact pin for insertion into a through hole in a printed circuit board, said through hole having circular inner walls, said electrical contact pin having a longitudinal axis, said electrical contact pin comprising: an insertion portion for guiding said electrical contact pin into said through hole; a cross rib integrally formed with said insertion portion, said cross rib defining longitudinal V-shaped surfaces along said longitudinal axis; four fin-like contacts extending from said longitudinal surfaces towards distal ends, each of said fin-like contacts having a contact surface, two of said fin-like contact surfaces and said cross rib forming a cross section of a substantially letter C-shape, each of said fin-like contacts having a portion extending from said longitudinal surfaces towards said distal ends and curved inwardly toward the center of said V-shaped surfaces so as to conform to said circular walls of said through hole, wherein each of said inwardly curved portions extends a distance along the entire length of said fin-like contacts; and a guiding portion comprised of a leading portion of each of said fin-like contacts, said guiding portion having a guiding surface which is inwardly curved.
Claim 4
Dependent Claim
190 words
An electrical contact pin for insertion into a through hole in a printed circuit board, said through hole having circular inner walls, said electrical contact pin having a longitudinal axis, said electrical contact pin comprising: an insertion portion for guiding said electrical contact pin into said through hole; a cross rib integrally formed with said insertion portion, said cross rib defining longitudinal V-shaped surfaces along said longitudinal axis; four fin-like contacts extending from said longitudinal surfaces towards distal ends, each of said fin-like contacts having a contact surface, two of said fin-like contact surfaces and said cross rib forming a cross section of a substantially letter C-shape, each of said fin-like contacts having a portion extending from said longitudinal surfaces towards said distal ends and curved inwardly toward the center of said V-shaped surfaces so as to conform to said circular walls of said through hole, wherein each of said inwardly curved portions extends a distance along the entire length of said fin-like contacts; and a guiding portion comprised of a leading portion of each of said fin-like contacts, said guiding portion having a guiding surface which is inwardly curved.
Claim 5
Dependent Claim
44 words
An electrical contact pin according to claim 2 wherein the inward curve of said guiding surface has a varying degree of curvature, wherein the degree of curvature first increases and then decreases along said longitudinal axis from said insertion portion to said contact surfaces.
