Description

The present invention relates to a device for mounting a switch unit and other parts without applying unnecessary force to the parts.

[Prior Art] As an example to be compared with the present invention, as shown in FIG. 2, a component 1 such as a switch unit which is a vehicle seat slide position detecting switch is provided on both sides of a frame 2 having a substantially U-shaped cross section. A configuration is conceivable in which the provided flange 3 is attached to the base 5 by tightening it with a fastener 4 such as a screw.

[Problems to be Solved by the Invention] Thus, when the component 1 is mounted on the frame 2 having the flange 3, the external angle θ of the flange 3 with respect to the frame 2 is
When the external angle θ becomes an acute angle slightly smaller than 90 ° due to the variation of (i.e., the flange 3 is formed so as to gradually move away from the base 5 toward the tip direction), the fastener 4 When the flange 3 is fastened to the base 5, a force in the direction of fastening the component 1 is generated as shown by an arrow F, and both side surfaces of the outer shell of the component 1 are slightly deformed, which adversely affects the internal mechanism and causes a malfunction. It may be a factor.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve the above-mentioned problems and to provide a device for mounting this part without applying unnecessary force to the switch unit and other parts.

[Means for Solving the Problems] The present invention is a device for attaching a component by fastening flanges provided on both sides of a frame having a substantially U-shaped cross section to a base with a fastener, the component being in the frame. And the convex portions provided on both side surfaces of the component are inserted into holes (or concave portions) provided on both side surfaces of the frame to hold the component in the frame, and the base is the component. Is in non-contact with, and the flange constitutes a component mounting device formed so as to gradually approach the base in the direction of the tip thereof.

Further, the device is a device for mounting a component by fastening flanges provided on both sides of a frame having a substantially U-shaped cross section to a base with a fastener, the component being fitted in the frame, and both sides of the frame. The convex portion provided on the inner surface is inserted into the concave portions (or holes) provided on both side surfaces of the component so that the component is held by the frame, the base is not in contact with the component, and the flange is the tip thereof. The component mounting device may be formed so as to gradually approach the base in the direction.

[Operation] According to the present invention, the flange gradually approaches the base in the direction of the tip thereof (for example, when the frame side surface and the base surface are at a right angle, the flange has an outside angle of 90 ° with respect to the frame side surface). Since it is formed with an obtuse angle (for example, about 91 ° to 93 °) that slightly exceeds the above, when attaching the parts by tightening the flange to the base with fastening tools, force acts in the direction that both side surfaces of the frame open to each other. Therefore, unnecessary force is not applied to the parts.

In this case, as the flange is slightly displaced in the base direction, the frame is also slightly displaced in the base direction, but the bottom surface of the component does not come into pressure contact with the base and the base does not contact the component. Therefore, no force is applied to the upper and lower surfaces of the outer shell of the component.

Further, since the component is fitted and held in the frame to prevent the component from falling off, the localization of the component in the frame is not impaired by the non-contact between the component and the base.

[Embodiment] An embodiment of the present invention will be described with reference to FIG. 1 and FIGS.

In this embodiment, for example, bent flanges 3 provided on both sides of a metal frame 2 having a substantially U-shaped cross section are fastened to a base 5 with a fastening tool 4 such as a screw, a rivet, or a driving tack, and an outer shell, for example. Is a device for attaching the component 1, which is a synthetic resin switch unit.

The component 1 is fitted in the frame 2, and the convex portions 6 provided on both side surfaces of the component 1 are inserted into the holes 7 (or concave portions) provided on both side surfaces of the frame 2 to hold the component 1 on the frame 2. It Of course, by providing convex parts on both inner surfaces of the frame 2,
You may insert this into the recessed part (or hole) provided in the both sides of the component 1.

The base 5 does not contact the component 1. For this purpose, the base 5
Although the concave portion 8 is provided on the base plate 5, if the base plate 5 is flat without the concave portion 8, the height of both side surfaces of the frame 2 can be made higher. Further, a through hole may be provided in the base 5 instead of the recess 8.

Then, the flange 3 is provided with a base 5 toward the tip thereof.
(For example, when the side surface of the frame 2 and the base 5 are at a right angle, the flange 3 has an obtuse angle (about 91 ° to 93 °) where the outside angle θ slightly exceeds 90 ° with respect to the side surface of the frame 2). Is formed.

Explaining the rest of the structure, a plunger 9 that is slid from the outside is provided on the front surface of the component 1, and a terminal 10 is provided on the rear surface. From the rear end of the frame 2, there is provided a bent end piece 11 that extends rearward while contacting the rear surface of the component 1.

According to the present embodiment, since the flange 3 is formed so as to gradually approach the base 5 in the direction of its tip, when the flange 3 is fastened to the base 5 with the fastening tool 4, the component 1 is attached. A force (the first
The arrow F) in the figure acts so that no unnecessary force is applied to the component 1.

In this case, as the flange 3 is slightly displaced in the direction of the base 5, the frame 2 is also slightly displaced in the direction of the base 5, but the lower surface of the component 1 is not pressed against the base 5, Since there is no contact between the component 1 and the component 1, the component 1
No force is applied to the upper and lower surfaces of the outer shell.

Further, since the component 1 is fitted and held in the frame 2 and is prevented from falling off, the non-contact between the component 1 and the base 5 impairs the localization of the component 1 in the frame 2. Never.

[Advantages of the Invention] As described above, according to the present invention, there is provided a device in which flanges provided on both sides of a frame having a substantially U-shaped cross section are fastened to a base with a fastener, and the components are attached to the base. Since it is formed so as to gradually approach the base toward
When mounting the parts by tightening the flange on the base with a tightening tool, a force acts on both sides of the frame to open each other, and unnecessary force is not applied to the parts.

In this case, as the flange is slightly displaced in the base direction, the frame is also slightly displaced in the base direction, but the bottom surface of the component does not come into pressure contact with the base and the base does not contact the component. Therefore, no force is applied to the upper and lower surfaces of the outer shell of the component.

Further, since the component is fitted and held in the frame to prevent the component from falling off, the localization of the component in the frame is not impaired by the non-contact between the component and the base.

Therefore, the present invention provides a device for mounting the switch unit and other parts without applying unnecessary force.
