The utility model discloses a curved pin of metal replacement metal straight pin utilizes the structural advantage buffering and the release stress of curved pin to thoroughly solve the product edge and discolour and the cracked harmfulness of product, improved product reliability.
Description
Technical Field
The utility model relates to a liquid crystal display technology field.
Background
The metal pin is a connector applied to the combination of the LCD and the PCB, and in practical application, most products use the straight metal pin, and in the practical application process of the products, the edge of the products is discolored, and even individual products have cracks extending from the metal pin to the inside of the products. Through the analysis of defective products, the phenomenon that the PCB is deformed or the front cover board is over-tightly leaned is found, so that the metal pins are twisted to a certain degree, and the connection stress between the pins and the LCD is uneven.
SUMMERY OF THE UTILITY MODEL
In order to solve the product edge and discolour and the cracked bad, the poor scheduling problem of reliability of product, the utility model provides a LCD panel and PCB board package assembly.
The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: the utility model provides a LCD panel and PCB board package assembly, is connected through the curved pin of metal between LCD panel and the PCB board, and the curved pin of metal includes two pipe corners on pin and the upper portion of lower part, and two pipe corner longitudinal symmetry install on pin upper portion, constitute the pipe corner groove between two pipe corners, and the bayonet installation in pipe corner inslot in LCD panel both ends, the bayonet installation in PCB board downthehole of pin lower part.
The two tube corners are of symmetrical wave-shaped structures.
And the lower part of the pin is provided with an arc-shaped structure.
The utility model discloses a LCD panel and PCB board package assembly adopts the curved pin of metal to replace the straight pin of metal, utilizes the structural advantage buffering and the release stress of curved pin to thoroughly solve the product edge and discolour and the cracked harmfulness of product, improved the product reliability.

Fig. 1 is a structure diagram of the metal bent pin of the present invention.
Fig. 2 is a diagram illustrating the assembly structure of the LCD panel and the PCB board according to the present invention.
In the figure: 1. pin, 2, tube corner, 3, tube corner groove, 4, LCD panel, 5, PCB board.
Detailed Description
The utility model discloses a LCD panel and PCB board package assembly are shown in fig. 1 and fig. 2, be connected through the curved pin of metal between LCD panel 4 and the PCB board, the curved pin of metal includes two pipe angles 2 on pin 1 and the upper portion of lower part, 2 longitudinal symmetries in two pipe angles are installed on 1 upper portion of pin, two pipe angles 2 are the wave structure of symmetry, constitute pipe angle groove 3 between two pipe angles 2, 4 both ends of LCD panel are bayonet to be installed in pipe angle groove 3, 1 lower part bayonet installation of pin is downthehole in the PCB board. The lower part of the pin 2 is provided with an arc structure.
The structure of the LCM product is not changed, the use reliability of the LCM product is improved by utilizing the structural difference of the metal bent pins on the premise of not increasing the cost of raw materials, and effective support is provided for solving the structural stress release and buffering of the product.
The working principle is as follows: when the metal pins are subjected to external force, such as deformation of the PCB or over-tightening of a customer front cover plate. The metal pins generate certain stress, which causes uneven stress on the connection point between each pin terminal and the LCD. The bending degree of the metal bent pin can effectively release stress. Thereby reducing the amount of deformation of the pin terminals.
The assembling process comprises the following steps: select the curved pin of metal of phase-match camber according to product pin length, make 3 opening directions in pipe angle groove face the LCD electrode connection limit, the adjustment micrometer of spiral, make the ITO electrode of pipe angle groove accurate alignment LCD, and the adjustment glass position, make two wave-shaped pipe angle grooves just install completely and do not receive the extrusion, align pipe angle and ITO electrode center on the LCD, and it is complete with LCD electrode embedding pin, the LCD panel both ends are cliied to the inside bulge of two 2 longitudinal symmetries in pipe angle, during the module product equipment, it steadily inserts and leans on to correspond LCD metal pin with the PCB plate pore, anchor clamps are fixed to make the PCB face weld again after parallel with the LCD panel. After the steps are completed, the metal bent pin can be assembled and installed, so that the purpose of releasing stress is achieved.
