[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for mounting electronic components for operation or connection to a chassis of an electronic device or the like.

[0002]

2. Description of the Related Art Electronic components for operation or connection (hereinafter referred to as "electronic components").
When the electronic component is mounted on a chassis of the electronic device, a board provided with a connector for wiring connection is mounted on the component, and the component is mounted on the chassis in order to simplify wiring work. FIG. 4 is a diagram showing the above-described conventional component mounting structure and mounting method, and shows a case where a seesaw switch (hereinafter, referred to as a switch) is mounted as a component. The connector 6 for connecting the wiring is provided on the board 5, and the board 5 is soldered and fixed to the terminal 4 a of the switch 4. The notch 7 provided in the chassis 7
Insert the switch 4 along the dashed line D from above c,
Next, when the switch 4 is pushed in the direction of the arrow E, that is, toward the inside of the chassis 7, the mounting is completed. In this case, the work of connecting the wiring is only required to connect the connector 6, so that the workability is better than that in which the wiring is directly soldered to the terminal 4 a of the switch 4.

[0003]

In recent years, downsizing of electronic devices has progressed, and there is a case where sufficient space in a chassis for mounting components such as switches cannot be obtained. So, for example,
By directly soldering the lead wire to the terminal of the switch, the size occupied by the switch, particularly the depth, can be reduced, but there is a problem that workability at the time of mounting the switch is deteriorated.

Further, in the mounting structure shown in FIG. 4, by providing the connector 6 on the same side as the switch 4 with respect to the board 5, the depth dimension can be reduced by the height of the connector 6. Since the switch 4 hits the chassis 7, the switch 4 cannot be mounted along the dashed line D. Therefore, even if an attempt is made to attach the switch 4 along the alternate long and short dash line F, there is a problem that the mounting operation is difficult due to the structure of the switch 4 and a load is applied to the locking portion 4b of the switch 4 to cause breakage.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a mounting structure which can reduce a depth dimension when components such as a switch are mounted, and which can be easily mounted and removed.

[0006]

According to the present invention, there is provided a plate for forming a mounting hole for mounting an electronic component for operation or connection in a vertical portion, and pressing the rear surface of the vertical portion on the rear surface of a horizontal portion. An L-shaped fixing plate 1 to which a spring 2 is fixed is provided. A positioning notch 7a for mounting the horizontal portion 1b is provided on a chassis 7 of the electronic device, and the fixing plate 1 is provided at the center of the positioning notch 7a. And a notch 7b for receiving the electronic component mounted on the chassis 7, the horizontal portion 1b is placed on the notch 7a for positioning of the chassis 7, and the leaf spring 2 and the vertical portion 1a By fixing the fixing plate 1 to the chassis 7 while holding the electronic component 7, the electronic component is mounted on the chassis 7 via the fixing plate 1, thereby solving the above problem.

The leaf spring 2 is fixed to both sides of the mounting hole 3. Further, the component receiving notch 7b has such a size that when the fixed plate 1 is fixed to the chassis 7, the electronic component attached to the fixed plate 1 does not come into contact with the chassis 7. Thus, the above-mentioned problem is solved.

[0008]

According to the present invention, after the electronic parts for operation or connection are mounted in the mounting holes of the vertical part, the rear part of the vertical part is brought into contact with the surface of the chassis and pushed down, so that the horizontal part is placed on the positioning notch of the chassis. The fixing plate is attached to the chassis while holding the chassis between the plate spring and the vertical portion.

FIG. 2 is a perspective view of a fixing plate 1 for mounting a one-touch mounting type switch viewed from the back side. The mounting plate 3 is provided with a mounting hole 3 for mounting the switch in the center of a vertical portion 1a which is vertical when used. A horizontal portion 1b is formed by bending the upper end of the plate 1 at a right angle, and a continuous portion 2a of the leaf springs 2, 2 is fixed to the rear surface thereof by spot welding to the horizontal portion 1b. The leaf springs 2 and 2 are in contact with the back surface of the vertical portion 1a, and generate a clamping force with the vertical portion 1a by the elasticity.
Then, the switch is pressed into the mounting hole 3 in the direction of arrow B to mount the switch on the fixing plate 1.

FIG. 1 shows a state immediately before the fixing plate 1 with the switch 4 mounted thereon is mounted on the chassis 7.
A board 5 is soldered to a terminal of the switch 4 attached to the fixed plate 1, and a connector 6 for wiring connection is provided on the board 5. Reference numeral 7 denotes a chassis.
Are provided with notches 7a, 7a for placing the horizontal portion 1b of the fixed plate 1 and positioning in the left-right direction, and a notch 7b for receiving the switch 4 when the fixed plate 1 is mounted in the center of the notches 7a, 7a. Has formed. The notch 7b has a width and a depth such that the switch 4 does not come into contact with the chassis 7 on the peripheral edge thereof.

And 8 is a top cabinet,
An opening 8a on the side surface for exposing the switch 4 to the outside
Is provided. Next, a method of attaching the fixing plate 1 to the chassis 7 will be described. 3A and 3B are cross-sectional views taken along line AA of FIG. As shown in FIG.
Of the vertical portion 1a is brought into contact with the front surface of the chassis 7, and the fixing plate 1 is pushed down vertically (in the direction of arrow C). Is inserted between the leaf springs 2 and 2 and the vertical portion 1a. And the horizontal portion 1b is a notch 7a of the chassis 7,
When the fixed plate 1 comes into contact with the fixed plate 7a, the fixed plate 1 is completely mounted, and the fixed plate 1 is firmly mounted on the chassis 7 by the clamping force between the leaf springs 2 and 2 and the vertical portion 1a (see FIG. 3B).

Thereafter, if the top cabinet 8 is fixed to the chassis 7 by covering it, the switch 4 fits into the opening 8a and is fixed. In this embodiment, the case where the seesaw switch is attached has been described. However, other electronic components for operation or connection, for example, an inlet, an outlet, a connector, and the like can be attached.

[0013]

According to the present invention, when an electronic component for operation or connection is mounted on a chassis, the depth occupied by the component can be reduced, which is effective for miniaturization of the device. Also, since there is no need for screwing work when mounting components, mounting and dismounting can be easily performed. Further, since no load is applied to parts such as the switch at the time of attachment and detachment, accidents such as breakage of attachment parts can be prevented.
