Abstract
Abstract An ejector mechanism for a connector having a header, comprises a pivot extending from a surface of the header and having a head portion and a narrow portion extending downward from the head portion, wherein the head portion has a cross section greater than a cross section of the narrow portion. A lever defines a hole pivotably engaged with the pivot of the header and comprises a driving member and an engagement portion on opposite sides of the hole. An ejection plate is linked to and driven by the driving member of the lever, and defines a cutout for movably receiving the narrow portion of the pivot, wherein the ejection plate is retained at a constant vertical position by the head of the pivot. A push bar is engaged with the engagement portion of the lever and moves the ejection plate via the driving member of the lever upon receiving a push force.

Claim 1
Independent Claim
175 words
An ejector mechanism for a card connector having a header, comprising: a pivot extending from a surface of the header, said pivot including a circular head portion and circular narrow portion; the narrow portion extending downward from the head portion, wherein the head portion has a cross section greater than a cross section of the narrow portion; a lever defining a hole pivotably engaged with the pivot of the header and comprising a driving member and an engagement portion on opposite sides of the hole; an ejection plate linked to and driven by the driving member of the lever, and defining a cutout for movably receiving the narrow portion of the pivot, wherein the cutout is so dimensioned that the ejection plate is retained in a vertical direction by the head portion of the pivot; said lever being positioned between said ejection plate and said header; and a push bar engaged with the engagement portion of the lever for moving the ejection plate via the driving member of the lever upon receiving a push force.
Claim 2
Dependent Claim
175 words
An ejector mechanism for a card connector having a header, comprising: a pivot extending from a surface of the header, said pivot including a circular head portion and circular narrow portion; the narrow portion extending downward from the head portion, wherein the head portion has a cross section greater than a cross section of the narrow portion; a lever defining a hole pivotably engaged with the pivot of the header and comprising a driving member and an engagement portion on opposite sides of the hole; an ejection plate linked to and driven by the driving member of the lever, and defining a cutout for movably receiving the narrow portion of the pivot, wherein the cutout is so dimensioned that the ejection plate is retained in a vertical direction by the head portion of the pivot; said lever being positioned between said ejection plate and said header; and a push bar engaged with the engagement portion of the lever for moving the ejection plate via the driving member of the lever upon receiving a push force.
Claim 3
Dependent Claim
35 words
