Abstract

Abstract An ejector is provided for ejecting a daughtercard from an elongated slot formed in an electrical connector socket housing. The ejector includes a body having a mechanism for ejecting an end of the daughtercard adjacent the ejector out of the elongated slot upon movement of the ejector relative to the socket housing. The body is also formed to include first and second crimp surfaces for engaging an end edge of the daughtercard to stabilize the daughtercard in the socket. A mechanism is also provided for biasing the ejector body in a direction toward the daughtercard to hold the first and second crimp surfaces against the daughtercard. The first and second crimp surfaces are preferably convergent to accommodate daughtercards having various lengths and thicknesses.
