Electrical connector

摘要

An electrical connector (1) mounted on a daughter backplane circuit board is used to mate with a complementary connector (2) mounted on the primary backplane circuit board. The connector (1) includes a top housing (11) and a bottom housing (12) and inner circuit boards (3) installed therebetween. Rows of paired signal contacts (5) and grounding plates (4) are arranged in an alternating sequence within the bottom housing (12) to engage with the inner circuit boards (3). Two projections (37) extend out of edges of every inner circuit board (3) so that the inner circuit board (3) can be positioned after the projections (37) are inserted into corresponding holes (15, 19) formed respectively in the top and bottom housing (11, 12) when the connector (1) is assembled.
