Abstract

The invention provides a circuit board installation fixing structure and a liquid crystal display device. The circuit board installation fixing structure comprises a cover plate and fixing pieces. The cover plate is provided with a top plate and lateral plates. The fixing pieces are provided with abutting-connection portions and clamping portions. The fixing pieces are formed on the lateral plates in a rotatable mode and rotate between releasing positions and locking positions. When the fixing pieces are at the releasing positions, circuit boards can move relative to the cover plate. When the fixing pieces rotate to the locking positions, the abutting-connection portions are connected with the circuit boards in an abutting mode so as to limit the freedom degree, in the direction perpendicular to the top plate, of the circuit boards and the clamping portions are clamped with the edges of the circuit boards so as to limit the freedom degree, in the direction parallel to the top plate, of the circuit boards. The circuit board installation fixing structure simplifies the installation process and improves the production efficiency.

Description

technical field [0001] The invention relates to the field of display devices, in particular to a fixing structure for fixing a circuit board in a metal cover plate. Background technique [0002] In addition to the exterior styling components of the front and rear covers, the liquid crystal display device also has a liquid crystal panel, a circuit board that realizes various electrical functions and supplies power, and is resistant to electromagnetic interference (EMI) and radio frequency interference (RFI) And the protection of electrostatic discharge (ESD) is also becoming more and more important. Therefore, it is necessary to set up a metal cover to shield the circuit board to prevent the interference of electronic noise signals and electrostatic damage, and at the same time to protect the sparks caused by electrical components. [0003] refer to figure 1 A circuit board installation and fixing structure shown includes a metal cover plate 1a and a circuit board 2a, the me...
