Patent ID: 8444424

Claim:
A card edge connector comprising: a longitudinal insulative housing defining a longitudinal direction and a thickness direction perpendicular to the longitudinal direction, the insulative housing having a central slot extending along the longitudinal direction for insertion of a memory module; a plurality of contacts retained in the insulative housing, the contacts having contacting portions arranged at two sides of the central slot in the thickness direction and protruding into the central slot for mating with the memory module; and an ejector rotatablely attached to one longitudinal end of the insulative housing for latching with or ejecting the memory module, the ejector comprising a main portion, an ejecting portion extending from a first end of the main portion and along the longitudinal direction for ejecting the memory module out of the central slot, a locking portion extending from a second end of the main portion opposite to the first end and along the longitudinal direction for latching with the memory module, and a lever portion extending from the second end and along the thickness direction to beyond the insulative housing so as to define an operating room upwardly beside the insulative housing along the thickness direction; wherein the lever portion extends from only one side of the second end along said thickness direction with a distance not less than a width dimension of said main portion in said thickness/transverse direction so as to be asymmetrical with the main portion of the ejector.
