Abstract

A connector assembly is provided having a receptacle connector mateable with a header connector. The assembly includes an insulated housing and a plurality of terminal modules mounted to the insulated housing. The terminal modules have an insulated molded body enclosing multiple connector contacts having opposed mating portions. Each terminal module includes a contact formed into at least one differential pair. The connector assembly further includes conductive ground shields mounted to and located between the terminal modules. Each ground shield includes at least one ground contact pair located proximate at least one differential pair of connector contacts. The ground contact pair includes a primary ground contact and a secondary ground contact extending different distances from the body of the ground shield to electrically engage a corresponding header ground shield at two points along the length of the header ground shield to inhibit the header ground shield from operating as a radiating antenna.

Description

technical field [0001] Preferred embodiments of the present invention generally relate to an electrical connector assembly with a receptacle connector mateable with a plug connector, in a small package and with high signal performance characteristics. Background technique [0002] In the electronics industry, right-angle connectors are often used to make electrical connections between two printed circuit boards or between a printed circuit board and leads. Right-angle connectors generally have a large number of pin-receiving terminals, and at their right angles, have pins (eg, compliance pins) that electrically connect to a printed circuit board. A post or a post connector on another printed circuit board can thus be inserted into these pin-receiving terminals to effect an electrical connection therebetween. The transmission frequency of electrical signals through these connectors is very high, and not only requires the impedance balance of each contact in the terminal modu...
