Abstract

An improved ejector mechanism is disclosed in conjunction with a header connector into which an IC pack is loaded and from which it is ejected. The IC pack includes a shell having a vertically extending leading face and at least one row of contacts extending a horizontal distance defining a contact array. A unitary ejecting lever is pivotally mounted to the header connector, with one end of the lever being effective to engage and eject the IC pack from the header connector. A unitary push-rod is reciprocally axially movably mounted on an appropriate support at one side of the header connector. One end of the push rod is engageable with the opposite end of the ejecting lever for pivoting the lever in response to movement of the push-rod. The one end of the ejecting lever engages and ejects the IC pack along a leading face thereof in an area defined horizontally by the distance the row of contacts extends and vertically by the height of the leading face of the memory card.

Claims

1. In an eject mechanism for ejecting a generally rectangular memory card from a connector assembly,

said memory card including:

a leading face extending a given vertical distance in a first direction; and

a plurality of card contacts communicating with the leading face and arranged in a contact array having at least one row extending a given horizontal distance in a second direction, said row defined by a first end contact located at a first end of the row, and a second end contact located at an opposite end of the row;

said connector assembly including;

a housing for receiving the memory card; and

a plurality of terminals mounted in the housing and arranged in a terminal array adapted to mechanically and electrically engage the contact array of the memory card, the terminal array having at least one row defined by a first end terminal adapted to engage the first end contact of the memory card contact array and a second end terminal adapted to engage the second end contact of the contact array;

said eject mechanism being operatively associated with the housing and including;

an elongated actuator mounted on one side of the housing; and

an eject member coupled to one end of the actuator and including a projection adapted to eject the memory card from the connector assembly;

wherein the improvement comprises;

the projection of the eject member engages the leading face of the memory card on a portion thereof inside an area defined horizontally by the horizontal distance the row of the contact array extends, and vertically by the vertical distance the leading face extends.

2. The eject mechanism as set forth in claim 1 wherein the eject member comprises a one-piece unitarily stamped &

formed member.

3. The eject mechanism as set forth in claim 1 wherein the eject member comprises a one-piece unitarily molded member.

4. The eject mechanism as set forth in claim 1 wherein the projection of the eject member is adapted to engage the leading face of the memory card below the contact array of card contacts.

5. The eject mechanism as set forth in claim 4 wherein the connector assembly is further defined by a connector centerline extending along a center of the connector housing and including a point along the terminal array located approximately midway between the first end terminal and the second end terminal, said connector centerline configured to be generally coincident with a card centerline extending along a longitudinal axis of the memory card and including a point along the contact array located approximately midway between the first end contact and the second end contact, wherein the projection of the eject member is positioned approximately along the connector centerline and is adapted to engage the leading face of the memory card approximately along the centerline thereof.

6. The eject mechanism as set forth in claim 1 wherein the housing of the connector assembly further comprises a bottom wall including means for guiding the projection of the eject member into engagement with the leading face of the memory card.

7. The eject mechanism as set forth in claim 6 wherein the means for guiding the projection of the eject member comprises a generally triangular-shaped cutout formed in the bottom wall of the housing.

8. The eject mechanism as set forth in claim 1 wherein the eject member is pivotally mounted to the connector assembly by way of complementary interengaging pivot means between the housing and the eject member.

9. The eject mechanism as set forth in claim 8 wherein the complementary interengaging pivot means comprises a pivot boss integrally formed on the bottom wall of the housing and a complementary pivot recess formed on the eject member intermediate opposite ends thereof.

10. An eject mechanism for ejecting a generally rectangular memory card from a connector assembly in an ejecting direction,

said memory card including

a leading end with card contacts mounted therein, the leading end having a leading face extending a vertical distance in a direction perpendicular to said ejecting direction, said card contacts arranged in at least one row including a first end contact located at a first end of the row, and a second end contact located at the opposite end of the row, said at least one row defining a contact array extending a horizontal distance in a direction perpendicular to both the ejecting direction and the vertical direction,

said connector assembly including

a housing for receiving the memory card,

a plurality of terminals arranged in a terminal array within the housing and adapted to mechanically and electrically engage the card contacts of the memory card, and

guide means for guiding the memory card between an inserted position wherein the card contacts of the memory card are electrically connected to the terminals of the connector assembly and an ejected position spaced from the inserted position,

the eject mechanism being operatively associated with the housing and comprising:

a manually manipulatable elongated actuator positioned on one side of the housing; and

an eject lever pivotally connected to one end of the actuator and including a projection adapted to engage the memory card and to move the memory card to its ejected position, wherein the projection engages the leading face of the memory card on a portion thereof inside an area defined horizontally by the horizontal distance which the contact array extends, and vertically by the vertical distance which the leading face extends.

11. In a connector apparatus for mechanically and electrically connecting a memory card to an underlying electrical device,

the memory card including a shell with a leading end within which is mounted a plurality of receptacle contacts, and

the connector apparatus including:

an electrical connector having a housing with a plurality of pin contacts mounted therein adapted to electrically engage the receptacle contacts of the memory card, the housing including a bottom wall having a board-mounting face adapted to be mounted on a printed circuit board of the underlying electrical device,

guide means extending from the connector housing adapted to guide the memory card into engagement with the electrical connector, and having a channel integrally formed therein, and

an ejector mechanism for ejecting the memory card from the connector, the ejector mechanism including

an eject lever pivotally mounted to an integral with the connector housing, and

an elongated actuator arm reciprocally mounted within the channel of the guide means coupled to one end of the eject lever and having a push-button at one end for manual actuation thereof to effect the pivoting of the eject lever,

the improvement in the connector apparatus comprising;

an integrally formed pivot boss on the board-mounting face of the bottom wall of the connector housing;

a complementary pivot recess integrally formed 6n the eject lever for mounting to the pivot boss of the housing;

aperture means located in the bottom wall of the housing for guiding a portion of the eject lever into engagement with the leading end of the memory card; and

an ejecting projection formed on one end of the eject lever for engaging a portion of the leading end of the memory card shell to effect ejection thereof,

whereby upon manual actuation of the actuator arm, the eject lever pivots about the pivot boss of the connector housing and the ejecting projection is guided along the aperture means to eject the memory card from the connector.

12. The connector apparatus as set forth in claim 11, the memory card further defined by a centerline extending along a longitudinal axis of the memory card shell, wherein, upon actuation of the actuator arm, the ejecting projection engages the memory card shell approximately along its centerline.
