Abstract:
A fastener for CPU radiating module, said CPU radiating module including from top to bottom a fin radiator, a CPU, and a CPU seat to which said CPU is connected; said fastener being used to bind said fin radiator, said CPU and said CPU seat of said CPU radiating module into a firmly associated unitary body; said fastener being an integrally formed one-piece body and comprising an elongated pressing part and a control part; said pressing part being substantially V-shaped and having a downward bent central portion to give two ends thereof some extent of elasticity, a top of said downward bent central portion of said pressing part being partially provided with a raised area that gives said pressing part an enhanced strength to resist against quick elastic fatigue thereof, a first end of said pressing part extending outward to first form a T-shaped head portion having two sideward projected lugs and then further extending outward from said T-shaped head in such a manner that a handle in the form of a substantially rectangular loop is formed at outer side of said T-shaped head for an operator to conveniently manipulate said fastener with fingers at said handle, the first end of said pressing part keeping extended from said loop-shaped handle backward to pass below and beyond said two lugs of said T-shaped head before turning downward to provide said control part; a top portion of said control part located below said T-shaped head being tightly bound to said T-shaped head by bending said two lugs downward to clamp two sides of said top portion of said control part, and a lower portion of said control part being provided with a first retaining hole for elastically engaging with a first catch provided on said CPU seat; and a second end of said pressing part being bent downward to form a tail on which a second retaining hole is formed for elastically engaging with a second catch on said CPU seat.
