In addition, the wear resistance and corrosion resistance of the material are both excellent, which significantly improves the service life of the card and greatly reduces the fixation problem caused by material aging or wear. At the same time, its elastic properties allow the card to deform appropriately when subjected to external force, effectively buffer and absorb impact, thereby protecting the light bar from damage. Compared with the traditional bolt connection method, this fixing method has stronger adaptability to various vibrations and impacts that may be encountered during the production, transportation and use of LCD TVs. At the same time, this method solves many problems of the traditional bolt installation method, such as cumbersome operation, long time consumption, difficulty in later maintenance, and possible damage to the light bar;

[0026] 2. The utility model sets a first arc chamfer and a second arc chamfer. The first arc chamfer is designed at the top of the insertion hole, which provides sufficient space for the rotation of the card and avoids obstruction of the card during the rotation. Moreover, this design enables the card to smoothly rotate from the inserted state to the fixed state, thereby improving the efficiency and smoothness of installation. The second arc chamfer set at the bottom of the card plays a role in buffering and reducing friction when the card abuts against the installation strip. By reducing the area of ​​direct contact and reducing the contact pressure, the second arc chamfer effectively reduces the wear and tear that may occur to the card during long-term use, thereby extending the service life of the card.
