Abstract

Abstract A connector apparatus for a memory card comprises a one-piece integrated metallic frame having a cross member and a pair of guide rails integrally extending from the cross member. Mounting means in the form of narrow slots are integrally formed on at least one guide rail to allow the push rod of an ejector mechanism to be mounted on the guide rail. Alternatively, the mounting means may be symmetrically formed on both guide rails to allow selective mounting of the push rod on either guide rail. Various other components of the ejector mechanism are mounted to the one-piece frame via respective tab and slot mechanisms to reduce the need for additional mounting hardware. Other functional components of the connector apparatus are integrally formed on the one-piece frame, including static discharge contacts, spring contacts for memory card grounding points, and mounting provisions for mounting the connector to a printed circuit board. A method of making the connector apparatus comprises forming a blank of the one-piece frame and then bending the blank at predetermined locations to form the integral guide rails.
