Abstract
Abstract The contact pin is characterized in that the three resilient legs are symmetrically displaced upon insertion of the pin (10) in a hole (15) of a printed circuit in such a manner that the outer legs (19,21) are bended towards one another so as to obtain a V-shaped configuration while the inner leg (20) acts like a wedge and is clinged between the two outer legs.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
128 words
An electric contact pin for printed circuits, provided with a central portion adapted to resiliently secure the pin in a hole of the printed circuit, in which said central portion has two longitudinal through cuts to form three resilient legs, the outer legs of which are bended in one direction in the plane of the cut, while the inner leg is bended in opposite direction, characterized in that the three resilient legs are symmetrically displaced upon insertion of the pin (10) in a hole (15) of a printed circuit in such a manner that the outer legs (19, 21) are bended towards one another so as to obtain a V-shaped configuration while the inner leg (20) acts like a wedge and is clinged between the two outer legs.
Claim 2
Dependent Claim
128 words
An electric contact pin for printed circuits, provided with a central portion adapted to resiliently secure the pin in a hole of the printed circuit, in which said central portion has two longitudinal through cuts to form three resilient legs, the outer legs of which are bended in one direction in the plane of the cut, while the inner leg is bended in opposite direction, characterized in that the three resilient legs are symmetrically displaced upon insertion of the pin (10) in a hole (15) of a printed circuit in such a manner that the outer legs (19, 21) are bended towards one another so as to obtain a V-shaped configuration while the inner leg (20) acts like a wedge and is clinged between the two outer legs.
Claim 3
Dependent Claim
55 words
An electric contact pin according to claim 1, characterized in that the through cuts (17, 18) are realized so to obtain outer legs (19, 21) which are less thick than the central leg (20) to improve the bending towards one another upon insertion of the pin (10) in a hole (15) of a printed circuit.
Claim 4
Dependent Claim
29 words
An electric contact pin according to claims 1 and 2, characterized in that the three resilient legs (19, 20, 21) remain connected to the pinbody (10) with their extremities.
Claim 5
Dependent Claim
27 words
An electric contact pin according to claims 1 to 3, characterized in that one extremity of the inner leg (20) is cut away from the pinbody (10).
Claim 6
Dependent Claim
60 words
An electric contact pin according to claims 1 to 4, characterized in that the outer edges or surfaces of the resilient legs, which realize the contact areas with the inner side of a hole (15) in a printed circuit, are provided with a wave-shape configuration (22) so as to obtain a "cold welding" between the tinlayers from pin and hole.
Claim 7
Dependent Claim
31 words
An electrical contact pin according to claim 1, characterized in that the outer side (30) of the central leg is provided with a lengthwise and centrally disposed depression or groove (32).
Claim 8
Dependent Claim
37 words
Electrical contact pin according to claim 1, characterized in that the ratio between the width (M) of the central leg'(20) and the width (B) of the outer legs (19, 21) is mainly situated between 1,05 and 1,2.
Claim 9
Dependent Claim
31 words
Electrical contact pin according to claim ' 7, characterized in that the ratio between the widths (M/B) of the legs equals 1,13 with a material thickness (D) of + 0,63 mm.
Claim 10
Dependent Claim
39 words
Electrical contact pin according to claim 1, characterized in that the side walls of the central leg (20) are conically shaped (36) toward the inner side (34), to still improve the wedge like action of the central leg (20).
Claim 11
Dependent Claim
36 words
Electrical contact pin according to claim 1, characterized in that the rounded outer edges (R2) of the legs (19, 21) have a more important radius than the rounded inner edges (R1) of said legs (19, 21).
