SIDE LOCK ASSEMBLY FOR HEAT SINK AND MEMORY MODULES
An embodiment is a method and apparatus to provide a side lock assembly for a memory module with a heat sink A side clip has a clip base attached to a socket connector and a first clip member and a second clip member extending from the clip base. The first clip member has a terminal for attaching to a printed circuit board. The second clip member is spaced in parallel from the first member to form an opening. A side lock has a lock base and first and second lock members that form a slot. The first and second lock members flank the second clip member such that the second clip member fits into the slot and the first lock member fits into the opening.
1 . A side lock assembly comprising:
a side clip having a clip base attached to a socket connector and a first clip member and a second clip member extending from the clip base, the first clip member having a terminal for attaching to a printed circuit board, the second clip member being spaced in parallel from the first member to form an opening; and
a side lock having a lock base and first and second lock members that form a slot, the first and second lock members flanking the second clip member such that the second clip member fits into the slot and the first lock member fits into the opening.
2 . The side lock assembly of claim 1 wherein the second clip member has a curved member to allow a board pressing down by an expanding spring action and to constrain the board underneath the curved member by a return spring action.
3 . The side lock assembly of claim 1 wherein the lock base has a hole to accommodate a fastener to secure a metal sheet.
4 . The side lock assembly of claim 1 wherein one of the side clip and the side lock is made of a material from one of copper, aluminum, and an alloy of copper or aluminum.
5 . A board assembly comprising:
a socket connector attached to a printed circuit board (PCB);
a memory module inserted into the socket connector;
a heat sink covering the memory module; and
a side lock assembly attached to the PCB to secure the memory module and the heat sink, the side lock assembly comprising:
a side clip having a clip base attached to the socket connector and a first clip member and a second clip member extending from the clip base, the first clip member having a terminal for attaching to the PCB, the second clip member being spaced in parallel from the first member to form an opening, and
a side lock having a lock base and first and second lock members that form a slot, the first and second lock members flanking the second clip member such that the second clip member fits into the slot and the first lock member fits into the opening.
6 . The board assembly of claim 5 wherein the second clip member has a curved member to allow a board pressing down by an expanding spring action and to constrain the board underneath the curved member by a return spring action.
7 . The board assembly of claim 5 wherein the lock base has a hole to accommodate a fastener to secure a metal sheet.
8 . The board assembly of claim 5 wherein one of the side clip and the side lock is made of a material from one of copper, aluminum, and an alloy of copper or aluminum.
