Abstract
A fastener used in a blade server to secure a thermal module and a motherboard to a metal face panel, including a cushion member set between the metal face panel and the motherboard, an elastically compressible and electrically insulative spacer member set between the motherboard and the thermal module, a lock member fastened to the cushion member and the spacer member to lock the motherboard to the metal face panel, a locating member fastening the thermal module to the spacer member, and a spring member mounted on the locating member to keep the thermal module in close contact with a chip at the motherboard. The spacer member automatically adjusts the tightness between the thermal module and the chip at the motherboard, and isolates the digital grounding loop formed in the locating member and the thermal module from the analog grounding loop formed in the lock member and the metal face panel.
