Interleaving ejector latches enabling a reduced end-to-end spacing between memory module connectors

摘要

First and second memory module connectors are secured in end-to-end alignment on a circuit board for receiving memory modules along a central plane. Each memory module connector has an ejector latch pivotally coupled to the adjacent ends of the memory module connectors to pivot about an axis perpendicular to the plane. A distal portion of an upper arm of each ejector latch lies on opposite sides of the plane, such that the ejector latches interleave when either ejector latch is pivoted to an open position. The adjacent ends of the first and second memory module connectors are separated by a narrow gap, such that pivoting of the either ejector latch from a closed position to an open position will push the other ejector latch toward a closed position.

主权项

1. An apparatus, comprising:
a printed circuit board securing first and second memory module connectors in end-to-end alignment, wherein the first memory module connector has a first slot configured to receive a first memory module and the second memory module connector has a second slot configured to receive a second memory module, and wherein the first and second memory modules are centered on a common plane; the first memory module connector having a first ejector pivotally coupled to a first end of the first memory module connector about an axis perpendicular to the plane, wherein the first ejector has an upper arm extending from the pivot axis away from the printed circuit board and a lower arm extending from the pivot axis under the first slot, and wherein a distal portion of the upper arm of the first ejector lies only on a first side of the plane; and the second memory module connector having a second ejector pivotally coupled to a second end of the second memory module connector about an axis perpendicular to the plane, wherein the second ejector has an upper arm extending from the pivot axis away from the printed circuit board and a lower arm extending from the pivot axis under the second slot, and wherein a distal portion of the upper arm of the second ejector lies only on a second side of the plane; wherein the first end of the first memory module connector is separated by a narrow gap from the second end of the second memory module connector, wherein pivoting of the first ejector from a closed position to an open position causes the distal portion of the upper arm of the first ejector to interleave with the distal portion of the upper arm of the second ejector, and wherein pivoting of the second ejector from a closed position to an open position causes the distal portion of the upper arm of the second ejector to interleave with the distal portion of the upper arm of the first ejector; wherein the upper arm of the first ejector includes a first bumper extending toward the second ejector and aligned for engagement with the upper arm of the second ejector; wherein the upper arm of the second ejector includes a second bumper extending toward the first ejector and aligned for engagement with the upper arm of the first ejector; and wherein the first bumper lies only on the second side of the plane and the second bumper lies only on the first side of the plane.
