Abstract

PURPOSE:To attach a component simply and fix it surely and lower the cost by providing a slit part or a slit part connected with a hole part in an insulating material. CONSTITUTION:In the case that a projected part of a part is inserted from the back side to the front side, when the projected part is inserted into a round hole 2, following the insertion of the projected part into the round hole part, slit rising pieces 1a-1d between two neighboring slits 5 are raised upward since the diameter of the round hole part 2 is slightly smaller than the diameter of the projected part. Consequently, the slit rising pieces 1a-1d work as a spring back and the outer circumference of the projected part of the part to be attached is fixed and thus the part to be attached is surely fixed in the insulator 1.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an insulating material attachment mechanism that allows an electrically and functionally insulating insulating material to be easily attached to a component to be attached. .

[Conventional technology]

FIG. 3 is a plan view of an insulating material that has been commonly used in the past, and in FIG. 3, 1 is an insulating material.

A round hole 2 and a square hole 3 are formed at predetermined positions of the insulating material 1, and a double-sided tape 4 is pasted at a predetermined position between the round hole 2 and the square hole 3.

The round hole portion 2 and the square hole portion 3 serve as escape holes for convex portions of an attached component (not shown).

To attach this insulating material 1 to the part to be attached, double-sided
14 is adhered to the part to be mounted, and the convex part of the part to be mounted is inserted into the round hole part 2 and the square hole part 3.

Further, FIG. 4 is a plan view of another conventional insulating material. In the case of this 4th V, as in the case of 3rd V, a plurality of round holes 2 (two holes are shown in the figure) are provided at predetermined locations of the insulating material 1, and this insulating material 1 is attached to the attached part. At this time, it is inserted into the convex part and the round hole part 2 of the part to be mounted.

In addition, in this FIG. 4, the double-sided tape 4 as shown in FIG. 3 is not used.

[Problem to be solved by the invention] Since the conventional insulating material is configured as described above, the third
In the case of the insulating material shown in the figure, since it is attached to the part to be attached by contacting the double-sided strip 4, there are problems in that it requires time to remove the separator and increases the unit cost.

On the other hand, in the case of Fig. 4, although there is no problem as described above, the part to be attached is not firmly fixed to the insulating material 1,
There were problems such as displacement and falling off due to vibration.

This invention was made to solve the above-mentioned problems, and it is an insulating material attachment method that can shorten the work of attaching parts to the insulating material, ensure reliable attachment, and reduce the cost of parts. The purpose is to obtain a mechanism.

[Means to solve the problem]

In the insulating material attachment mechanism according to the present invention, a notch portion or a notch portion connected to a hole portion is provided in the insulating material.

[For production]

When attaching the part to be attached to the insulating material in this invention, by inserting the convex part of the part to be attached into the notch, or by inserting the convex part into the hole, the notch exhibits a springback function. This springback function allows the insulating material to be fixed and attached to the component to be attached.

(Embodiment) Hereinafter, an embodiment of the insulating material attachment mechanism of the present invention will be described based on the drawings. Fig. 1 is a plan view of one embodiment. In Fig. 1, the third recess and the fourth Fig. The same parts will be described with the same reference numerals.

In FIG.
is formed. A convex portion of an attached component (not shown) is inserted into this round hole 2, and the diameter of this round hole 2 is slightly smaller than that of the convex portion.

At the periphery of this round hole part 2, there are 4
Notches 5 are provided at certain locations.

By forming this cut portion 5, cut and raised pieces 1a to 1d are formed in two adjacent cut portions 5.

These cut and raised pieces 1a to 1d are flush with the insulating material 1 when the convex part of the mounted component is not inserted into the round hole 2.

Next, a case where a mounted component is attached to this insulating material 1 will be explained. In this case, the convex portion of the mounted component is inserted from the back side of the paper of the first V to the front side.

When this convex part is inserted into the round hole part 2, the diameter of the round hole part 2 is slightly smaller than the diameter of this convex part. The cut-and-raised pieces 1a-1d in between are lifted upward in the plane of the paper.

As a result, the cut and raised pieces 1a to 1d exhibit a springback function, fixing the outer peripheral surface of the convex portion of the part to be mounted, and reliably identifying the part to be mounted to the insulating material 1.

FIG. 2(a) shows a planar opening of a second embodiment of the present invention. In the case of this No. 27 faj, it is applicable when the convex part of the part to be attached is square, and it is possible to form a hole 78 in the insulating material 1 without forming the round hole part 2 as shown in FIG. A notch 5 in the shape of a letter is provided.

Vertical dimension a I! of this notch 5! It is formed to be approximately twice the size of the convex part of the part to be attached.
Further, the lateral dimension of the cut portion 5 is formed to be slightly larger than the dimension of this convex portion.

When attaching a mounted part to the insulating material 1 shown in FIG. 2(a), a case will be described in which a sheet metal 6 is attached as the mounted part, as shown in the sectional view of FIG. 2(b).

As is clear from this second To), a cut-and-raised portion 6a is formed at a predetermined location of the sheet metal 6 by cutting and raising it in the upper surface direction of the sheet metal 6. This cut and raised portion 6a is inserted into the cut portion 5 from the back side of the insulating material 1 to the front side.

At this time, the cut portion 5 is pressed against the outer circumferential surface of the cut and raised portion 6a, and the vicinity of the tip thereof is curved outward, exhibiting a springback function.

Thereby, the sheet metal 6 is fixed and attached to the insulating material 1 in the same way as in the case of the first opening.

It should be noted that resin-based (plastic) materials with high springback properties are effective for each insulating material 1 shown in FIGS. 1 and 2, but FAM, rubber, Himeron, etc. can also be used.

〔Effect of the invention〕

As described above, according to the present invention, a notch portion having a spring hack function is provided to fit the convex portion of the attached part, or a notch portion having a spring function is provided that is connected to a hole portion into which the convex portion is fitted. , and when the convex parts of the mounted parts are fitted, the mounted parts are attached to the insulating material by the springback function, so the mounting of the mounted parts can be simplified and securely fixed, and it is also cost-effective. It also has the effect of reducing
