Abstract
Abstract A round circuit board pin with an expanded mounting portion has a plurality of deformed segments alternatively spaced from each other in opposite quadrants along a length of the mounting portion. There are rows of wedge shaped voids between the segments and the voids in adjacent rows are staggered.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
83 words
An elongated round circuit board pin having an expanded mounting portion characterized by an irregular surface defined by segments between plural equispaced longitudinal rows of wedge shaped voids, each void having a pair of inwardly directed walls meeting at a longitudinal apex substantially parallel to the axis of the pin, the voids in adjacent rows being staggered, there being at least three voids in each row at least one void in each row longitudinally overlapping a pair of voids in an adjacent row.
Claim 2
Dependent Claim
83 words
An elongated round circuit board pin having an expanded mounting portion characterized by an irregular surface defined by segments between plural equispaced longitudinal rows of wedge shaped voids, each void having a pair of inwardly directed walls meeting at a longitudinal apex substantially parallel to the axis of the pin, the voids in adjacent rows being staggered, there being at least three voids in each row at least one void in each row longitudinally overlapping a pair of voids in an adjacent row.
Claim 3
Dependent Claim
22 words
A circuit board pin, as recited in claim 1, there being four rows of voids, the voids in alternate rows being opposed.
Claim 4
Dependent Claim
42 words
A circuit board pin, as recited in claim 2, said mounting portion being generally cylindrical, there being one more void in each of two opposed rows than in adjacent rows, thereby presenting a transitional lead-in at each end of the mounting portion.
Claim 5
Dependent Claim
13 words
A circuit board pin, as recited in claim 3, said surface including asperities.
