Abstract:
A heat sink assembly removing heat from an electronic component having a heat generating surface and a plurality of mounting holes therein, comprising:a heat dissipating member having a base portion having a bottom surface and an upper surface with heat dissipating elements connected thereto; said bottom surface in flush thermal contact with a heat generating surface of an electronic component; said base portion defining a plurality of base apertures therethrough; said base apertures being substantially aligned with a plurality of mounting holes through the heat generating surface of said electronic component;a cam assembly having a support body; said cam assembly furthering including a connection body pivotally connected thereto about a pivot axis; said connection body having a first transverse dimension extending away from said pivot axis in a perpendicular direction defining an open position and a second transverse dimension, greater than said first transverse dimension, extending from said pivot axis in a perpendicular direction different than said first transverse dimension by a predetermined number of degrees about said pivot axis defining a locked position with said connection body contacting said upper surface of said base portion urging said bottom surface of said base portion of said heat sink assembly into flush thermal contact with said heat generating surface; at least one leg having a free end with an opposing end connected to said support body in a direction substantially perpendicular to said pivot axis; a retention member connected to said free end of said at least one leg; said at least one leg being routed through a selected one of said base apertures and one of said mounting holes corresponding to said selected one of said base apertures; said retention member preventing said free end of said at least one leg from being withdrawn from said selected base aperture and corresponding mounting hole upon pivoting of said connection body from said open position to said locked position.
