ELECTRICAL CONNECTOR FOR DIRECT CONNECTION TO PLATED THROUGH HOLES IN CIRCUIT BOARD

摘要

A pluggable electrical connector (10) is provided having contact elements (2 0) with first ends (32) soldered to a daughter board (40), mid-sections (36) which are crimped and bent through ninety degrees, and second ends (34) which have a converging portion and which terminate in bifurcated conical contact portions (34) whic h make contact with the rims of contact-quality plat- ed through holes (51) of a mother board (50). By causing contact between the rim and the cone surface, normal forces greater than the mating force are generated. The connector housing (30) includes self- centering funnel openings (66) adjacent the mother board for centering the converging portions (37) of the contact elements (20 ) therein in a nominal position and for acting as a pre- loading stop. The housing also includes side-wall locking tabs (72) which ho ld adjacent rows of contacts at identical fixing points relative to the ninety-degree bend to ensure identical spring parameters for all contact elements.
