Abstract

Abstract An electrical connector adapted to protect its signal circuits against power surges for at least ESD protection, having a conductive shell (60) with a transverse flange (64) on which are mounted components such as diodes (100) having first electrodes soldered thereto for grounding. A plurality of discrete straps (114) extend from second electrodes of the diodes to respective the contacts (20) and define circuits electrically connecting the contacts to the diodes. The dielectric housing (30) includes slots (46) along side surfaces within which intermediate strap sections 118 of the straps are retained, and a lateral flange (42) of the housing coextends along the transverse shell flange on each side and has recesses (54) within which the diodes are disposed, with channels (48) extending inwardly along the lateral flanges to the slots to retain transverse contact sections of said straps therein. The discrete straps (114) can be joined to carrier strips defining lead frames (110) to facilitate handling and assembly.
