Abstract

Abstract A SIMM socket with a metal latch for retaining a SIMM therein is provided. The socket includes a housing having a SIMM receiving slot and a plurality of terminals with contact beams extending into the slot. The SIMM is inserted into the slot in a first angular alignment with minimal insertion forces, and is rotated into a second alignment for achieving high quality electrical connection with the contact beams of the respective terminals. A metal latch is provided for releasably retaining the SIMM in the preferred angular alignment within the socket. The latch is stamped and formed from a unitary piece of metallic material and includes a housing engaging portion and a deflectable SIMM engaging portion. The housing includes walls for controlling the types and ranges of deflection that are permitted for the SIMM engaging portion.
