Abstract
Abstract An electrical connector is provided for receiving a daughtercard having an end edge formed to include a notch therein and having a plurality of conductive surfaces formed thereon. The connector includes a socket formed to include an elongated slot for receiving the daughtercard therein and including a plurality of electrical terminals for engaging the plurality of conductive surfaces formed the daughtercard for electrically coupling the daughtercard to the socket. The connector also includes an ejector coupled to an end of the socket. The ejector includes first and second side panels defining a slot therebetween for receiving the end edge of the daughtercard therein, and first and second raised surfaces formed on the first and second side panels of the ejector, respectively, for engaging opposite sides of daughtercard to apply a retention force directed normal to the daughtercard upon insertion of the daughtercard into the socket. The ejector also includes a locking head formed integrally with the first side panel and configured to engage the notch formed in the daughtercard to provide a vertical retention force to the daughtercard.
