Abstract
Abstract A projection-type male connector component includes a buttress of insulative polymeric material surrounded by a number of electrically conductive contacts electrically isolated from each other. The male component is designed to mate with an equal number of female cantilever beam contacts. The buttress is provided with a tapered end and the male contacts are bent over this tapered end so that the female contacts touch the male contacts when the male and female contacts are mated rather than the insulative material from which the buttress is made. In this way, excessive wear of the female contacts is avoided.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
137 words
A male connector component comprising: an electrically insulative substrate having a substantially flat surface; a buttress including an electrically insulative portion and electrically conductive portions extending substantially perpendicularly from said flat surface of said substrate, said buttress having an octagonal cross-section where said buttress meets said substrate and including a tapered tip having a quadrilateral cross-section; four electrically conductive contacts forming said conductive portions of said buttress and inset into said insulative portion of said buttress and electrically insulated from each other, said contacts each having a substantially flat surface forming one of the surfaces of said buttress and a bent tip tapering in both width and thickness and inset into one of said buttress tip quadrilateral surfaces such that a surface of said bent tip of said contact is substantially coplanar with said one quadrilateral surface.
Claim 2
Dependent Claim
137 words
A male connector component comprising: an electrically insulative substrate having a substantially flat surface; a buttress including an electrically insulative portion and electrically conductive portions extending substantially perpendicularly from said flat surface of said substrate, said buttress having an octagonal cross-section where said buttress meets said substrate and including a tapered tip having a quadrilateral cross-section; four electrically conductive contacts forming said conductive portions of said buttress and inset into said insulative portion of said buttress and electrically insulated from each other, said contacts each having a substantially flat surface forming one of the surfaces of said buttress and a bent tip tapering in both width and thickness and inset into one of said buttress tip quadrilateral surfaces such that a surface of said bent tip of said contact is substantially coplanar with said one quadrilateral surface.
Claim 3
Dependent Claim
57 words
A male connector component according to claim 1 wherein each of said contacts have a substantially trapezoidal cross-section defined by a shorter side forming a surface of said buttress, a longer side substantially parallel to said shorter side and inset into said moldable material, and sloping sides connecting the ends of said shorter and said longer sides.
