Abstract
A locking device for mounting a heat dissipating device to a CPU mounted on a printed circuit board, includes a back plate mounted below the circuit board and a retainer. The back plate includes a plurality of posts extending upwardly through the circuit board and engaging with screws thereat. The retainer includes a mounting section attached to the heat dissipating device and a plurality of spring locking sections extending radially from the mounting section. The locking sections are downwardly pressable to engage with the respective posts and screws whereby the retainer mounts the heat dissipating device to the electronic component.
Claims17
An assembly comprising:
- a circuit board on which an electronic component and a plurality of fasteners surrounding the electronic component are provided;
- a heat dissipating device placed on the electronic component;
- and
- a retainer attached to the heat dissipating device and comprising a plurality of locking sections elastically deformed to engage with the fasteners respectively;
- wherein the fasteners are adjustable to adjust the deformation of the locking sections to thereby provide an adjustable contact force between the heat dissipating device and the electronic component.
A combination comprising:
- a circuit board on which an electronic component and a plurality of posts surrounding the electronic component are provided;
- a heat dissipating device placed on the electronic component;
- and
- a retainer comprising a mounting section attached to the heat dissipating device and a plurality of elastic locking sections extending radially from the mounting section;
- wherein the locking sections are pressable to engage with the posts respectively whereby the retainer mounts the heat dissipating device to the electronic component.
A locking device for mounting a heat dissipating device onto a heat generating component, comprising:
- a plurality of fasteners having locations of surrounding said heat generating component, each of said fasteners defining at least two engagable extensions;
- and
- a retainer attached to said heat dissipating device and having a plurality of locking sections corresponding respectively to said fasteners, each of said locking sections being engagable with one of said at least two extensions of each of said fasteners so as to provide at least two kinds of pressured contacting between said heat dissipating device and said heat generating component.
