Abstract
Abstract Disclosed is a connector equipped with an improved ejection mechanism wherein the ejection mechanism includes an ejection rod and a push button directly mounted to the end of the ejection rod for movement between an operative and an inoperative position. The ejection rod has a rectangular flat head formed at one end thereof, and the push button has a corresponding head-retaining space formed therein for receiving the rectangular flat head of the ejection rod. The head-retaining space forms a generally L-shaped slot and includes a first head-holding section extending in a direction generally along the longitudinal dimension of the push button, and a second head-holding section extending generally perpendicular to the first head-holding section. The push button is in its operative position when the head of the ejection rod is in the first head-holding section, and the push button is in its inoperative position when the head of the ejection rod is in the second head-holding section. The push button may further include a resilient section adjacent to the head-retaining space adapted to apply a resilient force to the head of the ejection rod during movement of the push button between its operative and inoperative positions.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
186 words
An eject mechanism for ejecting a card from a card-receiving electrical connector, comprising: an elongated ejection rod (6) mounted along one side of the connector and having a rectangular flat head (11) formed at one end thereof; and a generally rectangular push button (30) attached directly to the ejection rod for rotatable movement between an operative position and an inoperative position and including a head-retaining space (12) formed at one end thereof for receiving the rectangular flat head (11) of the ejection rod (6), wherein the head-retaining space (12) includes a generally L-shaped slot having a first head-holding section (13) extending in a direction along the longitudinal dimension of the push button (10) for holding the push button in its operative position, and a second head-holding section (14) extending generally perpendicular to the first head-holding section for holding the push button in its inoperative position, whereby, when the head of the ejection rod is in the first head-holding section, the push button is aligned with the ejection rod and a user can apply force to the push button to eject the card from the electrical connector.
Claim 2
Dependent Claim
186 words
An eject mechanism for ejecting a card from a card-receiving electrical connector, comprising: an elongated ejection rod (6) mounted along one side of the connector and having a rectangular flat head (11) formed at one end thereof; and a generally rectangular push button (30) attached directly to the ejection rod for rotatable movement between an operative position and an inoperative position and including a head-retaining space (12) formed at one end thereof for receiving the rectangular flat head (11) of the ejection rod (6), wherein the head-retaining space (12) includes a generally L-shaped slot having a first head-holding section (13) extending in a direction along the longitudinal dimension of the push button (10) for holding the push button in its operative position, and a second head-holding section (14) extending generally perpendicular to the first head-holding section for holding the push button in its inoperative position, whereby, when the head of the ejection rod is in the first head-holding section, the push button is aligned with the ejection rod and a user can apply force to the push button to eject the card from the electrical connector.
Claim 3
Dependent Claim
48 words
The eject mechanism as set forth in claim 1 wherein the head-retaining space further includes a resilient section (17) adjacent the L-shaped slot adapted to apply a resilient force to the head of the ejection rod during movement of the push button between its operative and inoperative positions.
Claim 4
Dependent Claim
20 words
The eject mechanism as set forth in claim 2 wherein the resilient section (17) comprises a deformable oblique wall (17a).
Claim 5
Dependent Claim
52 words
The eject mechanism as set forth in claim 1 wherein the first head-holding section and the second head-holding section of the push button include U-shaped engagement recesses (15,16) into which a portion of the head of the ejection rod is positioned in the operative and inoperative positions of the push button, respectively.
Claim 6
Dependent Claim
159 words
An eject mechanism for an electrical connector comprising: a generally elongated ejection rod (6) having a head (11) formed at one end thereof; and a generally rectangular push button (30) rotatably attached to the ejection rod for movement between an operative and an inoperative position and including a head-retaining space (12) formed at one end thereof for receiving the head (11) of the ejection rod (6), wherein the head-retaining space (12) of the push button includes a generally L-shaped slot having a first head-holding section (13) extending in a direction generally parallel to the longitudinal dimension of the push button (10), and a second head-holding section (14) extending generally perpendicular to the first head-holding section, whereby when the head of the ejection rod is in the first head-holding section of the head-retaining space, the push button is in its operative position and a user can apply force to the push button to eject a device from the electrical connector.
Claim 7
Dependent Claim
159 words
An eject mechanism for an electrical connector comprising: a generally elongated ejection rod (6) having a head (11) formed at one end thereof; and a generally rectangular push button (30) rotatably attached to the ejection rod for movement between an operative and an inoperative position and including a head-retaining space (12) formed at one end thereof for receiving the head (11) of the ejection rod (6), wherein the head-retaining space (12) of the push button includes a generally L-shaped slot having a first head-holding section (13) extending in a direction generally parallel to the longitudinal dimension of the push button (10), and a second head-holding section (14) extending generally perpendicular to the first head-holding section, whereby when the head of the ejection rod is in the first head-holding section of the head-retaining space, the push button is in its operative position and a user can apply force to the push button to eject a device from the electrical connector.
Claim 8
Dependent Claim
43 words
The eject mechanism of claim 5 wherein the head-retaining space of the push button further comprises a resilient section (17) for providing a force on the head of the ejection rod during movement of the push button between its operative and inoperative positions.
