An edge card electrical connector is used for receiving the edge of a printed circuit board having contact pads on one or both sides adjacent to the so described edge. This two-piece right angle edge card connector includes an elongated dielectric housing having a receiving face with an elongated slot running the length of the connector creating a card insertion cavity. A plurality of PCI connector pins (peripheral component interconnect), on one or both sides of the card insertion cavity make contact with the pads located on the printed circuit board when it is inserted into the cavity. The PCI connector pins may also be stepped within the card insertion cavity with the primary engagement connectors forward of the secondary engagement connectors allowing for a staggered positioning and increased separation. This edge card electrical connector is uniquely constructed of two high density dielectric parts, a first segment and a second segment mated together with the PCI connector pins bent at a right angle to the elongated slot running the length of the connector and holding the two parts together. Each PCI connector pin is housed within a separate trough with sidewalls and alternating depths of the troughs to insure a proper separation and eliminate any possibility of contact or interference. A crimped nib on either side of the PCI connector pin restrains the connectors in place when they are inserted into the square PCI connector pin orifice. This new assembly process, along with the unique design of the two-piece right angle contact edge card connector allow the device to be used in a wider variety of applications than previous models of edge card connectors along with the ability of holding varying thickness of the edge cards and used with currents up to and exceeding three amperes. This right angle contact edge card connector has been designed for use in applications where computer peripherals, and add-on cards need to be mounted parallel to the motherboards due to limited space.
