Latch for card edge socket

摘要

A latch for use in an electrical connector which controls the movement of the circuit board in directions parallel and perpendicular to the path of insertion of the circuit board. The electrical connector has a dielectric housing with an elongated slot which is dimensioned to receive an edge of a circuit card therein. At least one latch receiving recess is positioned proximate an end of the elongated slot. In many applications, a latch receiving recess is provided at either end of the elongated slot. A first wall of the latch receiving recess is provided adjacent the elongated slot. The first wall has angled surfaces provided thereon. A latch is positioned in the respective latch receiving recess and is pivotally retained therein. Each latch has a pair of legs spaced from each other by a board receiving slot. The legs have a respective tapered surface which extends from a front surface of each leg to a respective side surface. The angle which the tapered surfaces project from the front surface is similar to the angle of the angled surfaces. Whereby when the latch is positioned in locking engagement with the circuit card, the tapered surfaces and angled surfaces cooperate with each other to prevent the movement of the latch and the circuit card in a direction perpendicular to the plane of insertion of the circuit card.
