Abstract
Abstract An electromechanical subassembly is comprised of a carrier having a body with a planar surface and multiple holes that extend from the planar surface into the body. A plurality of springy contacts are held in the holes; and they extend, in an uncompressed state, past the planar surface. The plurality of springy contacts include contacts of a first type which each exert a relatively small opposing force when compressed to the planar surface, and contacts of a second type which each exert a substantially larger opposing force when compressed to the planar surface.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
154 words
An electromechanical subassembly which is comprised of: a carrier having a body with a planar surface and multiple holes that extend from said planar surface into said body; a plurality of springy electrical contacts which are held in said holes and extend past said planar surface for making respective electrical connections to an external component; and, said plurality of springy electrical contacts including electrical contacts of a first type which each exert a small opposing force when compressed by said external component to said planar surface, and electrical contacts of a second type which each exert a larger opposing force when compressed by said external component to said planar surface; and, said first and second type springy electrical contacts being arranged in a pattern which reduces deflections in a predetermined critical region of said external component in comparison to the deflections which occur when all of said springy electrical contacts are said first type.
Claim 2
Dependent Claim
154 words
An electromechanical subassembly which is comprised of: a carrier having a body with a planar surface and multiple holes that extend from said planar surface into said body; a plurality of springy electrical contacts which are held in said holes and extend past said planar surface for making respective electrical connections to an external component; and, said plurality of springy electrical contacts including electrical contacts of a first type which each exert a small opposing force when compressed by said external component to said planar surface, and electrical contacts of a second type which each exert a larger opposing force when compressed by said external component to said planar surface; and, said first and second type springy electrical contacts being arranged in a pattern which reduces deflections in a predetermined critical region of said external component in comparison to the deflections which occur when all of said springy electrical contacts are said first type.
