Fixing latch member for heat radiating board of central process unit

Claim 1

A fixing latch member for securing a heat radiating board for a central processing unit, comprising: (a) two latch boards, each latch board including: a middle supporting panel section having first and second ends; a first resilient arm projecting from the first end of the supporting panel section; a second resilient arm projecting from the second end of the supporting panel section, the first and second resilient arms being formed respectively with slots aligned one with the other; a first latch section extending from an end of the first resilient arm, the first latch section terminating at an upwardly bent hook section; and, a second latch section extending from an end of the second resilient arm, the second latch section terminating at a downwardly bent hook section, the second latch section being formed with a slot aligned with the slots of the first and second resilient arms; (b) two linking levers, each linking lever including an elongated lever body passed through one of the latch boards, each linking lever having a first end adapted to hookingly engage the first latch section of one of the latch boards, and a second end formed with a connecting plate section passed through the slot of the second latch section, the connecting plate section having a locating hole formed therein; and, (c) a controlling lever including a handle section and two driving sections extending from opposed sides thereof for respective insert into the locating holes of the linking levers, the second latch sections of the latch boards abutting the controlling lever driving sections; the latch boards being adapted to respectively engage a heat radiating board disposed against an outer side of the central processing unit, the first and second latch sections being adapted respectively to align with and engage a plurality of latch holes in the central processing unit, whereby the controlling lever can be rotated to retract the first and second latch sections toward one another so as to firmly secure the heat radiating board on the central processing unit.
