Electrical connector assembly having grounding buses

摘要

An electrical connector assembly includes a receptacle connector and a mating plug connector. The receptacle connector has two rows of terminals, and a center internal wall with first ground buses disposed on opposite sides thereof. The plug connector has two rows of tongues with contacts and second ground buses respectively disposed on opposite outer and inner side surfaces thereof for engaging with the terminals and first ground buses. Each ground bus has two ribs for ensuring a reliable electrical connection. Adjacent tails of the first and second ground buses in a same row are spaced a distance larger than that between adjacent tails of the terminals and contacts in a same row, respectively.
