Abstract

The invention discloses a fixing assembly for fixing a printed circuit board on a bearing plate, wherein the bearing plate is provided with a lockhole. The fixing assembly comprises a first fixing component and a second fixing component which are used for being fixed on the printed circuit board, wherein the first fixing component is provided with a positioning hole with an internal thread; the second fixing component comprises a fixed column inserted into the positioning hole; the fixed column is provided with a fixing part with an external thread; the fixing part is locked in the positioning hole so as to fix the second fixing component on the first fixing component, and is firmly locked in the lockhole of the bearing plate.

Description

technical field [0001] The invention relates to a fixing assembly which can be used for fixing printed circuit boards. Background technique [0002] The printed circuit board plays the role of connecting various components in the computer, and its performance directly affects the quality of the entire computer. Generally, a plurality of fixing components are used to fix the printed circuit board on the bottom plate of a computer case. A conventional fixing component for fixing a printed circuit board includes a nut, a first component, a second component and an elastic member installed between the first component and the second component. The first component is fixed on the second component, and the free end of the first component is formed with a screw thread for lock fit with a nut. The first component passes through the installation hole on the printed circuit board and the locking hole on the bottom plate of the computer casing, thereby fixing the printed circuit board ...
