Description

Fastener

本發明涉及一種固定件。The invention relates to a fixing member.

部分擴展卡常透過壓合螺絲直接固定於主機板。然，由於壓合螺絲係透過底端之壓合螺紋部固定於主機板之孔內，當受到外力作用時，該壓合螺紋部容易鬆動，無法平穩固定擴展卡，容易導致擴展卡與主機板間之信號中斷。Some expansion cards are often fixed directly to the motherboard through press-fit screws. However, since the pressing screw is fixed in the hole of the motherboard through the pressing thread portion of the bottom end, when pressed by an external force, the pressing thread portion is easily loosened, and the expansion card cannot be smoothly fixed, which easily leads to the expansion card and the motherboard. The signal between the two is interrupted.

鑒於以上，有必要提供一種能夠牢固地將擴展卡固定於主機板之固定件。In view of the above, it is necessary to provide a fixing member capable of firmly fixing the expansion card to the main board.

一種固定件，包括於頂端開設有螺孔之一柱體、設於該柱體底端並擋止於一主機板頂面之一凸台及設於該凸台底面之一卡固部，該卡固部包括一連接部及一擋止部，該擋止部包括連接於該連接部底面之一固定部、分別連接於該固定部之兩端並擋止於該主機板之底面之一突起及一向上延伸之弧形之懸臂。A fixing member includes a column body having a screw hole at a top end, a boss disposed at a bottom end of the column body and stopping at a top surface of a motherboard, and a fixing portion disposed on a bottom surface of the boss plate, The fixing portion includes a connecting portion and a stopping portion, and the stopping portion includes a fixing portion connected to a bottom surface of the connecting portion, and is respectively connected to the two ends of the fixing portion and is blocked from protruding from a bottom surface of the main board And an arcuate cantilever extending upward.

相較習知技術，該固定件之凸台與突起及懸臂分別擋止於主機板之頂面及底面，能夠將固定件穩固地固定於主機板，從而能夠將一擴展卡牢固地固定於主機板。Compared with the prior art, the boss and the protrusion and the cantilever of the fixing member are respectively blocked on the top surface and the bottom surface of the motherboard, and the fixing member can be firmly fixed to the motherboard, so that an expansion card can be firmly fixed to the host. board.
