This makes it easy to mount electronic components, and when mounted on a board, each connection terminal corresponds to each joint, simplifying the connection.

<Prior Art> Conventionally, when attaching a liquid crystal display device such as an LCD to a substrate, a light emitting source for illuminating the display section of the LCD is required on the rear end side of the display section of the LCD. Therefore, it is necessary to provide a space between the LCD and the substrate sufficient to accommodate the light emitting source. Therefore,
In order to arrange the above LCD at a distance from the board,
The connection terminal of the LCD that connects the LCD and the substrate is provided in a long length. In addition, since the connection terminals of this LCD are weak in terms of strength, they have traditionally been
An electronic component mounting device is used to separately mount the LCD on the board and guide the connection terminals onto the board.

<Problems to be Solved by the Invention> By the way, since the conventional LCD did not display much content, the connection terminal only protruded from one side of the display section of the LCD. Therefore, there was not much difficulty in mounting this LCD on the electronic component mounting device.

However, as the display contents on the LCD display section become more diverse and complex, the number of connection terminals also increases, and it has become necessary to have them protrude from both sides of the display section. In this way, when the number of connection terminals increases so that the connection terminals protrude from both sides of the LCD display section, the LCD is mounted on an electronic component mounting device, and each of the connection terminals is attached to each side of the board. It has become difficult to match the connection parts and make connections, and the work efficiency of attaching LCDs and other devices to substrates has deteriorated.

Therefore, the present invention is an electronic component mounting device that makes it easy to mount electronic components such as LCDs, and when mounted on a board, each connection terminal corresponds to each joint and the connection can be easily made. The purpose is to provide

<Function> The present invention guides the connecting terminals by engaging the connecting terminals provided on both sides of the electronic component with the introduction grooves provided on both side walls of the holding member, and also guides the connecting terminals with the tongue piece. By inserting the connecting terminals into insertion holes drilled in the board, the tips of the connecting terminals can be temporarily positioned, and each of the connecting terminals can be made to correspond to each connecting part on the board.

<Embodiments> Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

The electronic component mounting device 1 according to the present invention includes a first
As shown in the figure, an electronic component, in this case a liquid crystal display (LCD) 3, is mounted on a substrate 2, and the lamp 4 is placed on the inside of the substrate 2 so that the display section 5 of the LCD 3 can be illuminated by the lamp 4. The main component is that a space is provided in which 4 can be stored.

First, the LCD 3, which is an electronic component mounted on the electronic component mounting device 1 according to the present invention, has a plurality of elongated connection terminals 6a,
6b is provided protrudingly.

The reason why the connection terminals 6a and 6b are long is because the lamp 4 that illuminates the display section 5 of the LCD 3 is disposed below the LCD 3, so the LCD 3 is mounted at a distance from the board 2. Because it has to be.

The electronic component mounting device 1 for mounting the above-mentioned LCD 3 on the board 2 includes a holding member 7 on which the display section 5 of the LCD 3 is placed and guiding the connection terminals 6a, 6b of the LCD 3 to the board 2. Constructed as. This hold member 7
consists of a top plate part 8 on which the display part 5 of the LCD 3 is placed, and side walls 9 and 10 continuous from both sides of the top plate part 8, and is bent into a substantially U-shaped cross section. ing. The inner side thereof has a space in which the lamp 4 can be accommodated.

This holding member 7 is made of a light-permeable synthetic resin, and is capable of irradiating the light emitted from the lamp 4 onto the display portion 5 of the LCD 3 through the top plate portion 8 of this holding member 7. It is becoming possible to do this. In addition, the above-mentioned top plate part 8 is the above-mentioned
A light-shielding paint is applied to the area other than where the display section 5 of the LCD 3 is placed, that is, the peripheral edge 8a of the top plate, and the light from the lamp 4 is applied to the display section 5.
This prevents leakage to other parties.

A lamp 4 serving as a light emitting source for illuminating the display section 5 of the LCD 3 is attached to a lamp board 11, and this lamp board 11 is attached to the back side of the substrate 2. The lamp 4 faces the inside of the holding member 7 through an opening 12 provided on the substrate 2. In this way, the lamp 4 is not directly attached to the board 2, but the lamp board 1
The reason why we decided to attach it to the board 2 via 1 is as follows.
This is to make it easier to replace the lamp 4.

Further, in order to display the display section 5 substantially uniformly when the display section 5 of the LCD 3 is irradiated by the lamp 4, a reflector 13 formed on the housing is attached to the inside of the holding member 7. It's summery. This reflector 13 has an insertion opening 14 formed in its bottom surface at a position corresponding to the opening 12 of the substrate 2 so that the lamp 4 attached to the lamp substrate 11 can be inserted therein.

This reflector 13 is molded from synthetic resin, has an inner surface as a reflective surface, and is formed to widen from the bottom side, and is a top plate of the holding member 7 on which the display section 5 of the LCD 3 is placed. It is attached so as to surround the lower surface side of part 8. Therefore, the top plate portion 8 of the holding member 7 can be irradiated with light from the lamp 4 substantially uniformly. If the top plate part 8 of the holding member 7 is made of a diffuser plate, the light from the lamp 4 can be more uniformly irradiated onto the display part 5 of the LCD 3 via the top plate part 8.

When attaching the reflector 13 to the inner side of the hold member 7, a locking piece 15 formed protruding from one side of the reflector 13 corresponds to the locking piece 15 on one side of the hold member 7. This is done by engaging a locking hole 16 provided at a position.

Further, tongue pieces 19 and 20 having different height positions are provided on the side walls 9 and 10 to protrude in a direction perpendicular to the introduction grooves 17 and 18, respectively. Insertion holes 21 and 22 are formed in the tongue pieces 19 and 20 so as to be continuous with the introduction grooves 17 and 18, respectively. Therefore, the connection terminals 6a, 6b engaged with the introduction grooves 17, 18
are easily inserted into the insertion holes 21 and 2 by being guided by the corresponding introduction grooves 17 and 18, respectively.
It is designed so that it can be inserted into 2.

Furthermore, the mounting height positions of the tongue pieces 19 and 20 on the side walls 9 and 10 are different from each other on the right side wall 9 and the left side wall 1.
The reason why this is different from 0 is that the above-mentioned LCD
3, and then insert the connecting terminal 6b on the other side into the insertion hole 22 of the tongue piece 20, which has a low mounting height. This is to allow insertion into the insertion holes 21 and 22 of the. In this way, tongue piece 1
If the mounting height positions of the terminals 9 and 20 are different so that the connecting terminal 6a can be inserted into the insertion hole 21 and the connecting terminal 6b can be inserted into the insertion hole 22 separately, the connecting terminals 6a and 6b on both sides can be inserted at once. This can be more easily inserted than inserting into the respective insertion holes 21 and 22. Therefore, the work of assembling the LCD 3 to the holding member 7 can be facilitated.

The insertion holes 21 and 22 of the holding member 7 into which the connection terminals 6a and 6b are inserted are used to temporarily position the tips of the connection terminals 6a and 6b so that they correspond to the connection parts 23 and 24 on the board 2. belongs to. Therefore, the tongue pieces 19 and 20 provided with the insertion holes 21 and 22 are connected to the connection terminal 6.
In order to facilitate the positioning of the distal end portions a and 6b, it is preferable to provide them as close to the proximal ends of the side wall portions 9 and 10 as possible.

In this embodiment, the tongue piece 20 on the lower side of the mounting height position is provided along the proximal edge of the side wall portion 10 to ensure the positioning of the connection terminal 6b and to securely position the holding member 7. is board 2
It allows you to stand stably on top.

The electronic component mounting apparatus 1, on which the LCD 3 and the reflector 13 are mounted as described above, is mounted on the board 2 in the following manner.

That is, the holding member 7 to which the LCD 3 and the reflector 13 are attached is placed at the mounting position on the board 2, and both side walls 9, 1 of the holding member 7 are
Temporary locking pieces 25 provided at both corners of the base end side of the base plate 2 are locked and positioned in locking holes 26 provided on the substrate 2. Then, the connection terminals 6a, 6 of the LCD 3
