Abstract
Abstract The present invention relates to the compliant section on contact elements which are received in plated through holes in printed circuit boards and are structured to hold such elements therein without soldering. More particularly, the invention discloses an improved structure relative to the legs forming the moving members of the compliant section. The invention further discloses an improved structure to stabilize the element against normal forces.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
71 words
A contact element of the type having a compliant section consisting of two sheared apart legs extending along a longitudinal axis, characterized in that the legs are pre-stressed by being initially spread apart in opposite directions along the shear plane and then pushed back towards each other along the same shear plane to a predetermined relative position prior to insertion into a hole in a printed circuit board or the like.
