Abstract: A connector assembly having a signal post receptacle subassembly and a ground post receptacle subassembly. The signal post receptacle assembly has a connector shell which is mounted on an electrical assembly chassis, and has an electrical insulation board which is supported by the connector shell, and has a group of signal posts extending through and supported by the electrical insulation board, and having a retainer plate assembly fixedly attaching the electrical insulation board to the connector shell. The ground post receptacle subassembly has a ground post plate mounted on the retainer plate assembly, and has a group of ground posts with each ground post being fixedly connected at one end thereof to the ground post plate. An electrical grounding path extends from each ground post, through the ground post plate, retainer plate assembly, and connector shell, to the electrical assembly chassis.

Abstract: An extender board connector is provided for connecting a circuit board card to a motherboard through an extender card for routing signals from the motherboard to the top of the extender for testing the circuit board card. The connector has first and second end portions, each having an integral mounting block with an octogonal slot. The connector also has first and second pins, each having an enlarged end portion and an octogonal middle portion and a grooved end portion with a ring groove. The octogonal middle portion of the pin is received in the octogonal slot of the connector for providing eight positions at each connector or a combination of eight-squared positions or 64 positions. The pin has a snap-on retaining ring received in the pin groove, and has a ring spacer disposed next to the snap-on retaining ring, and has a helical compression spring disposed between the ring spacer and the mounting block.
