Device with openings for receiving pins of electrical components

A device for receiving pins of electrical components in electrical connection, comprising:

• a substrate having an opening therein which extends axially into said substrate and which is bounded by an electrically conductive sidewall, said opening having a mouth, a central axis, an upper portion and a lower portion;
• said sidewall having a lower concave portion and a lip projecting generally radially inwardly adjacent said mouth of said opening;
• a pair of spring elements disposed within said opening which are in facing relationship to each other, each of said spring elements having an upper end portion, a center portion, and a terminal portion;
• said terminal portion of each said spring being disposed in said lower portion of said opening in engagement with said concave portion of said sidewall so as to retain said terminal portion of said spring in a fixed axial position, each said spring extending generally axially from a first side of said opening across said central axis to the opposite side of said opening, both of said spring elements crossing said central axis at substantially common location;
• and
• each said spring having a substantially sheet-like body, said terminal portion of each said spring contacting said sidewall in the vicinity of said lower portion of said opening, said upper end portion of each said spring engaging said lip of said sidewall in the vicinity of said upper portion of said opening so as to retain said spring within said opening, and said center portion of each said spring having a first portion which extends generally radially toward said central axis and a second portion which extends generally radially from said first portion toward said sidewall.
