Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of optics, in particular to an LCM structure for preventing wire breakage. Background Art
[0002] For the existing backlight design, two pads are set on the left and right ends of the circuit board. After the wires are soldered on the pads of the circuit board, due to the backlight structure, the wires need to be bent 90 degrees before being led out. The layout of the two wires will appear to be of unequal length. During use, the wires are pulled and the force on one end of the short wire is concentrated, which is easy to be broken. Figure 1 shown.
[0003] Based on the above reasons, this design proposes an LCM structure that prevents wire breakage. Summary of the invention
[0004] The utility model aims to provide an LCM structure which can prevent wire breakage.
[0005] To achieve the above-mentioned purpose, the utility model is implemented through such a technical solution, a LCM structure that prevents wire breakage, including a backlight unit, the backlight unit including a light-emitting diode, a circuit board, a wire, a rubber frame bracket and an optical film material, the wire is welded and connected to the circuit board, and pads are equidistantly arranged on the upper and lower sides of the tail end of the circuit board, and the wire is welded to the upper and lower pads.
[0006] Furthermore, the circuit board is welded to the wire and then embedded in the plastic frame bracket, and the optical film material is pasted inside the plastic frame bracket.
[0007] The utility model is aimed at the existing LCM backlight design. Two left and right pads are set at the end of the circuit board. After the wires are welded on the pads of the circuit board, due to the backlight structure, the wires need to be bent 90 degrees and then led out. The layout of the two wires will be unequal in length. During use, the wires are pulled and the force on one end of the short wire is concentrated and it is easy to be broken. In view of this problem, according to the above technical solution, the problem of wire breakage during the use of LCM products can be effectively prevented, thereby improving the yield and durability of LCM products. This solution has been introduced into mass production. BRIEF DESCRIPTION OF THE DRAWINGS
