Abstract
Abstract This invention describes a form of electrical connector to be used on printed circuit board assemblies which provides mechanical isolation from the effects of dynamic loading due to the different thermal expansions of the printed circuit board and the component leads and/or vibration. This is done by soldering a first loop of the connector to the printed circuit board and soldering the second loop of the connector to the component lead, and two loops being interconnected by a flexible member which minimizes force applied to the solder joint under dynamic loading conditions.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
108 words
An electrical connector of solderable, non-brittle material for making a connection between a terminal pad on one side of a printed circuit board and a component lead protruding through said one side which comprises: a first loop having a circular hole with a diameter larger than the diameter of said component lead, a second loop having a serrated opening, the inward extremities of the serrations defining a circular locus having a diameter less than said component lead; an insulating sleeve interposed between said terminal pad and said second loop and aligned concentrically within the hole of said first loop; and means for interconnecting the first and second loops.
Claim 2
Dependent Claim
