Abstract

PROBLEM TO BE SOLVED: To surely fit-insert a plurality of projecting sections provided on a fitting member into mounting holes without gap or with minimum gaps by forming thin sections which absorb the interval errors between the mounting holes of a panel and projecting sections of the insulating member in a connecting section which connects the projecting sections to each other. SOLUTION: On the Y2 side of a console panel 11, a fitting member 16 integrally formed with a connecting section 16A which connects fitting sections are provided and, on the Y1 side of the inserting sections, annular projecting sections 16c and 16d having outside diameters of D12 are respectively provided. In the connecting section 16A, in addition, a pair of thin sections α1 and α2 elongated perpendicularly to the plane of the figure are formed. When a difference occurs between the center-to-center distance of the mounting holes 11a and 11b of the console panel 11 and that of the projecting sections 16c and 16d of the member 16 due to the difference between the coefficients of thermal expansion of the resins respectively constituting the member 16 and panel 11, the difference between the deformation of the panel 11 and the member 16 can be absorbed by the deformation of the thin sections α1 and α2.

[0007]

However, the above-mentioned prior art has the following problems. Operation panel 1 is ABS
The fitting member 6 is formed of an acrylic resin or the like. Here, the coefficient of thermal expansion of the ABS resin is 9.5.
^{~10 × 10 -5 (/ ℃ ·} cm) or so, the acrylic resin is ^{5.0~9.0 × 10 -5 (/ ℃ ·} cm) or so, generally toward the ABS has a higher coefficient of thermal expansion . Therefore, when the environmental temperature is extremely high or low, the distance W1 between the centers of the mounting holes 1a and 1b in the operation panel 1 and the fitting member 6
Between the distance W2 between the centers of the protrusions 6c and 6d at
Dimensional differences are likely to occur. In order to absorb such a dimensional difference, the inner diameter D1 of the mounting holes 1a and 1b of the panel 1 is required.
Needs to be sufficiently larger than the outer diameter D2 of the ring-shaped projections 6c and 6d of the fitting member 6.

Further, from the relationship between the molding dimensional tolerance of the operation panel 1 and the molding dimensional tolerance of the fitting member 6, the projecting portions 6c and 6d connected to each other are formed into the mounting holes 1a and 1b.
It is necessary to make the inner diameter dimension D1 larger than the outer diameter dimension D2 in order to surely insert them together.
Due to the difference between the dimensions D1 and D2, the clearance S is provided between the mounting holes 1a and 1b and the projections 6c and 6d.
1 is formed. As a result, the mounting holes 1a and 1b,
The protrusions 6c and 6d cannot be fitted without moving each other, and the fitting member 6 rattles in the X direction in an assembled state. Light emitted from a light-emitting member such as a lamp provided inside the operation panel 1 leaks directly from the clearance S1 to the surface, and when the operation panel 1 is viewed from the front, the surroundings of the operation bodies 7 and 8 are reduced. From the light, and the appearance is degraded.

The present invention has been made to solve the above-mentioned conventional problems, and a plurality of projections provided on a fitting member are formed in a mounting hole formed in a panel without a gap or with a minimum gap. An object of the present invention is to provide an operation device that can be securely inserted.

SUMMARY OF THE INVENTION The present invention provides a panel having a plurality of mounting holes, an operating body that appears in the mounting hole, a convex portion to be inserted into each of the plurality of mounting holes, and the operating body. A fitting member having a through hole through which is inserted,
In an operating device having a hooking means for fixing the fitting member to the back surface of the panel, the fitting member is integrally formed with a connecting portion for connecting the convex portions, and the connecting portion has Is characterized in that a thin portion capable of absorbing an error between the interval between the mounting holes in the panel and the interval between the convex portions is formed.

The operating member is a member for rotating a rotary switch or a variable resistor, or a push button. Or, even if one of the operation tools is a display member,
Included in the present invention. That is, the same fitting member is provided with a convex portion located at the mounting portion of the operating body and a convex portion located at the mounting portion such as the display member, and each of the convex portions is inserted into a mounting hole formed in the panel. This is also the case.

Preferably, the engaging means is such that the panel and the fitting member are fitted to each other. For example, a hook-shaped engaging member is integrally formed on the panel side or the fitting member side. Is what it is.

In the present invention, since the connecting portion of the fitting member is formed with a thin portion so that it can be deformed, the distance between the centers of the mounting holes formed in the panel and the protrusion provided on the fitting member can be improved. Even if an error due to a difference in the molding dimension or a difference in the coefficient of thermal expansion occurs between the gap between the portions, it is possible to cope with the deformation of the connecting portion when the convex portion is mounted in the mounting hole.

Therefore, it is not necessary to form a large gap in advance between the fitting portion of the fitting member and the fitting hole of the panel, and the fitting portion and the fitting hole are fitted with no gap or with a minimum gap. Can be inserted. Therefore, the fitting member does not rattle with respect to the panel, and leakage of illumination light does not occur due to the clearance between the projection and the mounting hole.

It is preferable that the thin portion has a V-shaped cross section, and the fitting member can be cut at the thin portion.

In this configuration, when there is a large error in the distance between the center of the mounting hole and the distance between the projections, and the deformation cannot be absorbed by the deformation of the connecting portion, the connecting portion is folded at the thin portion to cut and separate. By doing, the convex portion formed on the fitting member,
It becomes possible to fit into each of the mounting holes formed in the panel.

Further, the fitting member is a light guide member for transmitting light for illuminating the periphery of the operation body. Or,
A member other than the light guide member, for example, only for supporting the operation body may be used.

a, 13a, 14a, and 15a are formed to have a thickness capable of being elastically deformed in the illustrated X-axis direction.

On the back surface (Y2 side (electronic device main body side)) of the operation panel 11, fitting portions 16L and 16R and a connecting portion 16A for integrally connecting the fitting portions 16L and 16R are integrally formed. A member 16 is provided. Fitting part 16
Ring-shaped protrusions 16c and 16d having an outer diameter D12 are provided on the Y1 side of L and 16R, respectively. Also,
Each of the projections 16c and 16d has a through hole 1 inside.
6e and 16f are bored, and the other portions are receiving portions 16a and 16b to which the operating bodies 17 and 18 are attached. Locked portions 16g, 16h, 16i, 16j extending in the Y2 direction are provided on the rear surface (rear portion) of the fitting member 16, respectively. The positions of the hooking members 13 and 14 are adjacent to the hooking portions 16h and 16i.
Through holes 16m and 16n for inserting the holes.

The inner width L11 between the hooking member 12 and the hooking member 13 and between the hooking member 14 and the hooking member 15
, The outer width dimension L1 between the hooked portion 16g and the hooked portion 16h and between the hooked portion 16i and the hooked portion 16j.
2 are formed sufficiently small, and the hooked portions 16g, 1
6h, 16i and 16j are connected to the locking members 12, 13, 14, 1
5 can be securely hooked. The fitting member 16 is a light guide member formed of, for example, a transparent resin such as acrylic, and receives light from a light emitting member (not shown) such as a lamp provided inside the operation panel 11. 1
6, the projections 16c and 16d are brightly illuminated.

The connecting portion 16A for connecting the fitting portion 16L and the fitting portion 16R is formed to have a thickness having a predetermined strength. The connecting portion 16A has a pair of thin portions α1 and α2 cut in a V-shaped cross section, each extending perpendicularly to the paper surface, and formed over the entire width of the connecting portion 16A in the width direction. When the thickness of the connecting portion 16A is t,
The thickness of the thin portions (V-grooves) α1 and α2 is formed to be approximately t / 2 or less, and the angle of the V-shape is approximately 90.
° is set. As shown in FIG. 1 (B), when the fitting member 16 is mounted on the back surface of the operation panel 11, the hooking members 13 and 14 are inserted into the insertion holes 16m and 16n, respectively. The provided hooked portions 16g, 16h, 16i, 16j are connected to the hooking members 12,1.
Hook portions 12a, 13a, 14 at the tips of 3, 14, 15
The fitting member 16 is attached to the back surface of the operation panel 11 by being elastically hooked to the a and 15a.

At this time, the projections 16c and 16d formed on the fitting member 16 are fitted into the mounting holes 11a and 11b of the operation panel 11. Therefore, the mounting holes 11a and 11b
The protrusions 16 c and 16 d of the fitting member 11 and the receiving portion 16
a, 16b and through holes 16e, 16f appear. When the operation panel 11 and the fitting member 16 are mounted on an electronic device main body (not shown), the rotating shaft or the pressing shaft 1 of the operation electronic components 19 and 20 provided on the electronic device main body are mounted.
9a and 20a enter the through holes 16e and 16f. The operation bodies 17 and 18 are mounted from the front side of the operation panel 11,
The joints 17a and 18a of the operating bodies 17 and 18
e and 16f, they are fitted to the rotating shafts 19a and 20a.

In the above, the ring-shaped projections 16c,
The size of the outer diameter D12 of the 16d is determined by the inner diameter D11 of the mounting hole 11a.
As described below, the difference between D11 and D12 is set very small. Therefore, in the assembled state, the protrusion 16
A gap (clearance) is hardly formed between the outer circumferences of c and 16d and the inner circumferences of the mounting holes 11a and 11b, or the gap is slightly formed. Therefore, each fitting portion 16
L and 16R are securely fitted in the mounting holes 11a and 11b, and can prevent the fitting member 16 from rattling in the X direction.
In addition, since little gap is formed between the protrusions 16c and 16d and the edges of the mounting holes 11a and 11b, light emitted from a light-emitting member such as a lamp provided in the electronic device main body emits light. And no leakage from the outer periphery of 16d to the front of the operation panel 11. That is, the operating tool 17
The outer peripheral portions of the and 18 are appropriately illuminated by the convex portions 16c and 16d, so that the appearance quality of the electronic device can be maintained.

Further, when the operating environment temperature becomes extremely high or low, the operation panel 11 may be changed due to a difference in thermal expansion coefficient between the acrylic resin or the like forming the fitting member 16 and the ABS resin or the like forming the operation panel 11. Mounting hole 11
A distance W1 between the centers of a and 11b and a distance W2 between the centers of the protrusions 16c and 16d of the fitting member 16 (see FIG. 3A)
There is a difference between In this case, the difference between the deformation amount of the operation panel 11 and the deformation amount of the fitting member 16 is determined by the thin portion α1
And α2 can be absorbed. For example, in a high-temperature environment, when the operation panel 11 having a high coefficient of thermal expansion is extended beyond the fitting member 16, the thin portions α1 and α
Due to the slight elongation of 2 (expansion of the angle of the V-groove), it is possible to prevent an excessive tension from acting on the fitting member 16. As shown in FIG. 2, when the operation panel 11 is warped due to thermal deformation, the fitting member 16 attached to the back surface of the operation panel 11 has a V-groove-shaped thin portion α1 formed in the connecting portion 16A and Warpage (a narrowing of the angle of the V-groove) easily occurs at the portion of α2. Therefore, the deformation of the fitting member 16 can follow the deformation of the operation panel 11.

As described above, the difference between the outer diameter D12 of the convex portions 16c and 16d formed on the fitting member 16 and the inner diameter D11 of the mounting holes 11a and 11b of the operation panel 11 is extremely small, and the convex portions 16c and 16d Can be fitted into the mounting holes 11a and 11b with almost no gap.
When warpage or the like occurs due to a difference in the amount of deformation between the fitting member 16 and the fitting member 16, unnecessary stress can be prevented from being generated in the fitting member 16 and the operation panel 11.

Also, due to an error in the molding dimension of the operation panel 11 and an error in the molding dimension of the fitting member 16, the mounting hole 1
Even if there is a difference between the distance between the centers of 1a and 11b and the distance between the centers of the protrusions 16c and 16d, the difference can be absorbed by deformation of the thin portions α1 and α2. Further, when the difference between the molding dimensions is large and both the projections 16c and 16d cannot be fitted into both of the mounting holes 11a and 11b, the connecting portion 16A is formed by a pair of thin portions α1 and α2 in a V-groove shape.
May be cut and separated, and the fitting portions 16L and 16R may be separately cut and separately mounted in the mounting holes 11a and 11b.

Further, as described above, the fitting portions 16L and 1L
6R are integrally formed, and each fitting portion 16L is formed as necessary.
And 16R, the fitting member 16 can be handled as one component, and component management is easy. In addition, although the case where the fitting member 16 is a light guide member provided on the back surface of the operation panel 11 has been described,
The present invention is not limited to the operation panel and the light guide member, but may be applied to various other members as long as one member is fitted to the other member between members having different thermal expansion coefficients. It is possible to apply.

[0028]

According to the present invention described in detail above, even if there is a difference in the amount of deformation between the panel and the fitting member due to thermal expansion or an error in the molding dimension between the panel and the fitting member, the two members can be used. The dimensional difference can be absorbed by the deformation of the thin portion formed in the connecting portion of the fitting member. Therefore, it is possible to prevent a gap from being formed in the fitting portion between the fitting member and the panel.
