Abstract
A multi-row right-angle type header is mounted upon a printed circuit board and includes a series of leaf-type spring contacts positioned on opposite sides of the pin field and are designed to effect electrical connection with the conductive shroud of the connector telescopically received within the housing. The spring contacts each include respective tail portions that extend rearwardly of the housing and are connected to the printed circuit board in such a way that the adverse effects of electric fields is attenuated. In another form of the invention, a shield structure is connected to the tail portions of the spring contacts to provide an additional increment of shielding. The present invention advantageously provides for the shielding of the terminal leads of headers and connectors in the context of right-angle mountings so as to attenuate electric field radiation from and between the various circuits and attenuate the effect of external fields on those circuits in a cost-effective manner.
