Abstract

This publication describes a mechanical latch for retaining and ejecting PCB cards such as memory modules into a connector on a main board. The latch has features that help align the card as it is inserted, which reduces the risk of damage to the card and the main board. It also has features that provide mechanical advantage for inserting and removing the card from the connector. Finally, the design is such that it does not require any additional space on the main board outside the space for the connector to implement, thereby making this latch more functional and more space conscious than present industry standard connector latches.

  Minimal Footprint Memory Module Connector Latch with Insertion/Removal Force Reduction and Self-Alignment Features

This publication describes a mechanical latch for retaining and ejecting PCB cards such as memory modules into a connector on a main board. The latch has features that help align the card as it is inserted, which reduces the risk of damage to the card and the main board. It also has features that provide mechanical advantage for inserting and removing the card from the connector. Finally, the design is such that it does not require any additional space on the main board outside the space for the connector to implement, thereby making this latch more functional and more space conscious than present industry standard connector latches.

A typical embodiment of the latch is shown below in Figures 1, 2, and 3. Figure 1 shows the design of the latch from the side in the closed position and Figure 2 shows the latches in the open position as a memory module is inserted into the connector. As the latches are opened, as in Figure 2, the card slides into the connector through the 2 arms of the latches; thus, the latch does not need to extend past the footprint of the connector in order to open. Figure 3 shows a top, front and side view of the latch. The top view shows the large surface the installer would push down on, in order to finish the installation into the connector. The side view highlights the design that allows for the minimal footprint feature. The t...
