Abstract
Abstract A pin-shaped contact element to be connected or fastened in a metallized conductor plate bore has a fastening portion with two sidepieces which are movable towards each other and which are connected to each other by a resilient, undulating connecting bridge, the edges of the side pieces which come into contact with the bore walls and the juncture between the bridge and the side pieces being rounded.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
192 words
A pin-shaped contact element for separable engagement in a metallized bore of a conductor plate comprising an insertable fastening contact element having two parallel sidepieces, a resilient connecting bridge connected to said sidepieces, each of said two sidepieces having two rounded ends spaced from each other by an intermediate portion, at least portions of each of said rounded ends contacting the bore walls at four spaced locations when the insertable fastening contact element is inserted in said bore without damaging said conductor plate, the connection between said two sidepieces and said bridge being rounded, said connecting bridge having a thickness which is about one-third the thickness of said sidepieces, said connecting bridge being connected to said intermediate portions of said sidepieces to thereby provide substantially even contact pressure at said four spaced locations where said portions of said rounded ends contact said bore walls, said connecting bridge having an undulating configuration providing for elasticity of the connecting bridge, whereby the insertable fastening contact element is elastically deformable when inserted into a bore which is smaller than the contact element and substantially returns to its original undeformed configuration when removed from said bore.
Claim 2
Dependent Claim
192 words
A pin-shaped contact element for separable engagement in a metallized bore of a conductor plate comprising an insertable fastening contact element having two parallel sidepieces, a resilient connecting bridge connected to said sidepieces, each of said two sidepieces having two rounded ends spaced from each other by an intermediate portion, at least portions of each of said rounded ends contacting the bore walls at four spaced locations when the insertable fastening contact element is inserted in said bore without damaging said conductor plate, the connection between said two sidepieces and said bridge being rounded, said connecting bridge having a thickness which is about one-third the thickness of said sidepieces, said connecting bridge being connected to said intermediate portions of said sidepieces to thereby provide substantially even contact pressure at said four spaced locations where said portions of said rounded ends contact said bore walls, said connecting bridge having an undulating configuration providing for elasticity of the connecting bridge, whereby the insertable fastening contact element is elastically deformable when inserted into a bore which is smaller than the contact element and substantially returns to its original undeformed configuration when removed from said bore.
Claim 3
Dependent Claim
48 words
A pin-shaped contact element according to claim 1 wherein each of said sidepieces has an inner wall, an outer wall and two end walls, said outer wall being joined to said end walls by rounded walls constituting the portions of the rounded ends which contact said bore walls.
Claim 4
Dependent Claim
60 words
A pin-shaped contact element according to claim 1 wherein said bridge has a central portion and two end portions, the axis of said two end portions being disposed at about a 45 degree angle relative to said sidepieces, said central portion having the configuration of a reverse bend the central axes of which subtend an angle of approximately 90 degrees.
Claim 5
Dependent Claim
83 words
A pin-shaped contact element according to claim 1 wherein said bridge has a central portion and two end portions, each of said end portions having a first section and a second section, said first sections being joined to the respective sidepiece the axes of each of said first sections extending from the respective sidepiece at an angle of approximately 90 degrees, said second section extending from said first section, the axes of said second sections extending approximately 221/2 degrees relative to said sidepieces.
Claim 6
Dependent Claim
31 words
A pin-shaped contact element according to claim 4 wherein said second sections each have the configuration of a reverse bend the axes of which subtend an angle of approximately 45 degrees.
Claim 7
Dependent Claim
30 words
A pin-shaped contact element according to claim 4 wherein said central portion has the configuration of a reverse bend the axes of which subtend an angle of approximately 45 degrees.
Claim 8
Dependent Claim
45 words
A pin-shaped contact element according to claim 6 wherein said reverse bend of said central portion defines a reversing point at the interior midpoint of said reverse bend, said reversing point being disposed approximately on a transverse midline passing through the midpoint of said sidepieces.
