DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to an LCD holder for mounting a liquid crystal display (hereinafter referred to as LCD) on a printed circuit board.

[0002]

2. Description of the Related Art As a method of attaching an LCD to a printed circuit board, there is a method of using an LCD holder. FIG.
FIG. 1 is an external perspective view showing a conventional technique of such an LCD holder for fixing an LCD to a printed circuit board. The LCD holder 50 is formed of resin and has a frame-shaped main body 52. The main body 52 has a mounting surface 5 on which an LCD is mounted.
The guides 54a, 54b, 54c and 54d for positioning the LCD to be mounted are integrally formed on the main body 52 at the four corners.

In addition, two LCD fixing members 56a and 56b for preventing and fixing the tilt of the LCD are formed integrally with the main body 52. LCD fixing member 56
Reference numerals a and b denote plate springs, which are bent outward to secure a space for the LCD and place the LCD on the mounting surface 53. When the LCD fixing members 56a and 56b are released, they return to their original positions to prevent or fix the LCD from tilting. FIG. 7 shows that the LCD 70 is LC-connected by the LCD fixing members 56a and 56b.
It is a fragmentary sectional view showing the state at the time of being fixed to D holder.

Returning to FIG. 6, the LCD connection pin guide 60
Is a guide for connection pins provided on the LCD connected to the printed circuit board. The connection pins of the LCD are bent vertically, and are respectively stored in the grooves 62 in a free state. FIG. 8 shows that a groove 62 of the LCD connection pin guide 60 has an LC
FIG. 9 is a partial cross-sectional top view when the state in which the connection pin 72 of D is housed is viewed from above. As shown by the arrow in FIG. 8, the connection pin 72 is in a free state in this state, and is not fixed until it is soldered to the printed circuit board.

FIG. 9 is a front view showing a state where the LCD 70 is mounted on the LCD holder 50 and attached to the printed circuit board 80. The connection pins 72 of the LCD 70 are inserted into the pin holes of the printed circuit board 80 while being housed in the grooves 62, and are soldered by the solder 90. As shown in FIG. 9, when the printed board 80 is a printed board for single-sided mounting,
In order to prevent the soldering iron from contacting the LCD holder 50 during soldering, a clearance of a height h from the printed board 80 to the LCD connection pin guide 60 is provided.

[0006]

However, in such a conventional LCD holder 50, when the LCD 70 is mounted, the two fixing members 56a and 56b must be simultaneously bent outward. For this reason, there has been a problem that the mounting operation has to be performed using both hands, and the workability is poor and a lot of assembly time is required.

Further, as described above, in the single-sided printed circuit board 80, it is necessary to secure a clearance between the LCD connection pin guide 60 and the printed circuit board 80 for soldering when soldering. . For this reason,
Inevitably, the connection pins 72 of the LCD 70 become longer. Since the connection pins 72 are merely accommodated without being fixed in the grooves 62 of the LCD fixing guide 60, the positions of the respective tips vary. In addition, since the number of connection pins is very large, each connection pin must be inserted one by one into a predetermined pin hole of the printed circuit board 80, so that workability is poor and much assembly time is required. There were also problems.

The present invention solves the above-mentioned problems of the prior art, and provides an LCD holder capable of shortening the assembling time by adopting a structure for improving the workability of mounting the LCD and mounting it on a printed circuit board. The purpose is to do.

[0009]

According to the present invention, in order to solve the above-mentioned problems, an LCD holder for mounting an LCD on a printed circuit board is curved outward so that the LCD can be mounted on the LCD holder. In addition, it has a plurality of LCD fixing members for preventing and fixing the LCD from tilting by returning to the original state after mounting, and a connecting member for connecting the plurality of LCD fixing members. When the connecting member is operated, the plurality of LCD fixing members simultaneously bend outward.

According to the present invention, an LCD holder for attaching an LCD to a printed circuit board is an LCD connecting pin formed with a plurality of holes into which connecting pins for electrically connecting the LCD to the printed circuit board are inserted. It has a fixed guide. The LCD connection pin fixing guide is located when the connection pin is inserted just above the pin hole of the printed circuit board to which the connection pin is inserted and soldered. Guide connection pins.

Further, according to the present invention, the LCD holder for attaching the LCD to the printed circuit board can be mounted on the LCD holder by curving outward, and can be returned to its original position after mounting. The LCD
A plurality of LCD fixing members for preventing or fixing the LCD, a connecting member for connecting the plurality of LCD fixing members, and a plurality of holes into which connection pins for electrically connecting the LCD to the printed circuit board are formed. LCD connection pin fixing guide. The LCD connection pin fixing guide is used to fix the position of the connection pin so that the connection pin is inserted and soldered. Is located directly above. When the LCD connection pins are inserted into holes formed in the LCD connection pin fixing guide, and the LCD is placed in a state where a plurality of LCD fixing members are simultaneously bent outward by operating a connecting member, each of the LCDs is placed. When the connection pin is attached, the connection pin is located at the position of the pin hole to be inserted in the printed board.
