Abstract
An electronic component contact which provides substantially lower insertion force while providing sufficient contact force to maintain good electrical engagement with a component lead. The contact includes a plurality of inwardly angled spring fingers which are laterally yieldable and which are of two or more different lengths. A component lead inserted into the contact initially engages the shorter spring fingers and thereafter engages the longer spring fingers, the sequential engagement of the spring fingers with the inserted lead providing substantially reduced insetion force. Once the lead is inserted into the improved contact, the normal contact forces of the fingers on the lead are sufficient to maintain good electrical engagement.
Claims8
An electrical contact providing a reduced, two-step insertion force for a component lead inserted therein, comprising:
- a ring portion defining an entrance end;
- a longitudinal axis extending symmetrically through said ring portion;
- a first plurality of resilient beams formed integral with and outwardly disposed from the ring portion and tapered inward toward said longitudinal axis extending symmetrically through the ring portion, said first plurality of beams being of a first length and formed symmetrically about said ring portion;
- and
- a second plurality of resilient beams of a length shorter than the length of said first plurality of beams formed integral with and outwardly extending from the ring portion and tapering toward said longitudinal axis, said second plurality of beams being formed symmetrically about said ring portion, said first and second plurality of resilient beams formed about said ring portion in an staggered symmetrical arrangement of first and second resilient beams wherein the component lead is insertable therein with reduced, two-step normal insertion force, initially engaging said first plurality of resilient beams and subsequently engaging said second plurality of resilient beams, and wherein said first plurality of beams and said second plurality of beams are independently formed with respect to one another.
