Abstract:
1. A fastening structure connecting a longitudinally extending thermal module to a mainboard, the thermal module comprising a plurality of transverse radiating fins arranged along a length thereof, a bottom surface disposed on the mainboard, an opposing top surface, and opposing side surfaces each comprising a recess, the fastening structure comprising: a first body section disposed on the mainboard and comprising a fastening portion for connecting the fastening structure to the mainboard; a second body section extending away from the mainboard, the second body section comprising: a third body section connected to the upper end of the second body section and extending over the top surface of the thermal module, the third body section comprising opposing first and second insertion sections on a bottom side of the third body section, each insertion section extending laterally inward; wherein in an unlocked position, the raised portions are pushed toward the opening, thereby resiliently pivoting the second end of the elastic press arm to move the retainer out of the opening, such that first and second insertion structures can engage within the recesses in the side surfaces of the thermal module, and wherein in a locked position, the elastic press arm is released within the opening such that the retainer is positioned within the opening and engages with a passage defined between two adjacent radiating fins, thereby longitudinally locking the fastening structure with the thermal module.
