[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is applied to, for example, a front panel of an audio equipment or the like or a remote control device constituted by combining a CD (compact disk) player and an MD (mini disk) player integrally. In particular, the present invention relates to a combination device such as an operation button device used in particular, and particularly to a first member having a plurality of projections such as an operation button and a second member having a plurality of fitting holes into which the projections are fitted.
The present invention relates to a combination device comprising a combination with the above member.

[0002]

2. Description of the Related Art Conventionally, generally, a large number of operation buttons required for using an acoustic device are mounted on a front panel or a remote control device of the acoustic device. The simplest method of mounting such operation buttons is to associate the number of operation buttons with the number of operation buttons provided on the front panel, etc., one by one. Are arranged in pieces.
However, in this individualized method, basically, as many dies as the number of operation buttons are required, so that not only the number of manufacturing steps for injection molding the operation buttons and the number of assembly steps for assembling are increased, It is uneconomical.

[0003] Therefore, in recent years, a technique of forming a plurality of operation buttons by one injection molding has been adopted. As a technique using such a technique, for example, a technique described in JP-A-4-315715 is known. This publication describes an integrated key button device for a switch used for an operation panel switch or the like of a portable wireless device.

[0004] This integrated key button device for a switch is
"A frame extending in a predetermined direction, a plurality of key buttons disposed in the vicinity of the frame along the predetermined direction, and extending in a direction orthogonal to the predetermined direction from a side of the frame so as to sandwich each key button. A pair of long sides, and a pair of short sides connected to both ends of each key button in a predetermined direction and connected to each end of the long side, and the thickness of these long sides and short sides With a hinge formed thinner than the thickness of the frame,
The frame, the key button, and the hinge part are integrally formed of synthetic resin, and by pressing a desired key button, one contact provided on the key button and the other contact provided on the substrate are brought into contact with each other. Did ".

According to such an integrated key button device for a switch, "each key button is integrally formed and supported on the frame via a pair of L-shaped hinge portions at both ends.
When the key button is pressed down, the upper surface is lowered while keeping the horizontal state, operability is improved, and the arrangement pitch in the X-axis direction of each key button is shortened and downsized, and the number of key buttons is increased. Furthermore, in the production, a runner using a synthetic resin molding die can be provided with a gate for each key button to perform injection molding, thereby improving moldability. "

[0006]

However, in such an integrated key button device for a switch, since a plurality of operation buttons are integrally formed in a state where they are connected in a horizontal direction or a vertical direction, a plurality of operation buttons are formed. When connecting two operation buttons,
Although it does not cause much problem, as the number of connected operation buttons increases, as the number increases, the variation in the size from the reference position to the operation buttons increases, and the pitch dimension between the operation buttons is within a predetermined range. It becomes difficult to guarantee. In addition, since there is a tolerance in the hole pitch of the fitting holes provided in the mating member to which these operation buttons are fitted, if the tolerances are amplified due to variations in the pitch size of each other, the operation buttons are not fitted. There was a problem that a situation in which a hole was not entered occurred.

[0007] Therefore, in the conventional key button device as described above, for example, when ten operation buttons are connected, practical use becomes impossible, and the connection is inevitably cut off. It was the current situation.

SUMMARY OF THE INVENTION The present invention has been made in view of such a conventional problem, and has a structure in which a convex block having one or more convex portions is configured to be elastically displaceable, and a hole pitch between fitting holes is provided. To allow the plurality of protrusions provided in the first member to be fitted in the plurality of fitting holes provided in the second member, respectively.
It is an object of the present invention to improve assemblability and yield.

[0009]

In order to solve the above-mentioned problems and to achieve the above object, the combination apparatus of the present application forms a plurality of convex block having one or two or more convex parts. And a first member in which all the convex blocks are elastically displaceably connected via one or more flexible portions and are integrally formed with each other, and a plurality of convex members in which all of the convex portions are fitted. A second member having a fitting hole;
A combination device which is used by combining the member with the second member, wherein all the projection blocks are provided with positioning depressions or positioning projections, and reference projections fitted with the positioning depressions or positioning projections. The second member is provided with a portion or a reference concave portion.

With the configuration described above, in the combination device of the present application, the positioning concave portion or the positioning convex portion provided in each convex portion block is fitted to the reference convex portion or the reference concave portion, so that the distance between the convex portions is reduced. By absorbing the pitch tolerance and the hole pitch tolerance between the fitting holes, all the convex blocks can be securely attached to the second member.

In this case, when the gap between the adjacent large-diameter fitting hole 30 and the small-diameter fitting hole 31 and the distance between the large-diameter convex portion 7 and the small-diameter convex portion 8 are different from each other. Also, since the hole diameter of the fitting hole is formed relatively rough and a sufficient gap is set between the fitting hole and the convex portion, the deviation of the length is absorbed and all The projection can be easily fitted into the fitting hole. On the other hand, the mounting positions of the convex blocks 3 to 5 are required to have a certain degree of positional accuracy from the relationship with the mounting position of the switch means (not shown).

In this regard, the operation button assembly 1 is formed by injection molding and is integrally formed with three convex blocks 3 to 5, but between adjacent convex blocks 3, 4 and 4, 5 Are elastically displaceable by the flexible portions 6 respectively. Therefore, even when a gap occurs between the interval between the positioning holes 25 and the interval between the positioning pins 35a to 35c, that is, even when a large tolerance of the pitch dimension occurs, the flexible portion 6 is not removed. The displacement can be easily absorbed by elastic deformation.

Next, while fitting the positioning holes 25 into the positioning pins 35a to 35c, respectively,
5 to 5 are respectively fitted to posture adjusting pins 36 provided in the upper flange portion 2b. And
By inserting each of the convex blocks 3 to 5 to a predetermined depth, the operation button assembly 1 is mounted on the button holder 2, and the assembling work of this combination device is completed.

In this case, by fitting all the posture adjusting pins 36 into the respective posture adjusting holes 26, each of the convex blocks 3 to 5 is adjusted to a predetermined posture and attached to a predetermined position. At this time, since each of the posture adjustment holes 26 is formed to be slightly laterally elongated, there is an error between the length from the positioning pins 35a to 35c to the posture adjustment pins 36 and the length from the positioning holes 25 to the posture adjustment holes 26. Even when such an error occurs, the error can be absorbed by the elongated hole, and the attitude adjusting hole 26 can be securely fitted to the attitude adjusting pin 36.

The positioning hole may be provided in the button holder 2 or the front panel 42. Similarly, the posture block has posture adjustment holes 26 and 54 which are recesses for posture adjustment, and posture adjustment pins 36 and 64 which are fixed protrusions fitted to the recesses are provided on the button holder 2 or the front panel 42. Although the example has been described, on the contrary, a posture adjusting pin, which is a posture adjusting convex portion, is provided on the convex block and a posture adjusting hole, which is a fixed concave portion, into which the posture adjusting pin is fitted is formed on the button holder 2 or the front panel 42. It is also possible to adopt a configuration provided.

Furthermore, an example in which the combination device having the above-described configuration is applied to audio equipment has been described. However, the present invention relates to an operation button, a display lamp, a meter and other similar parts,
The present invention can be applied to electronic devices, mechanical devices, and other devices in which a plurality of devices, devices, and the like are used. As described above, the present invention can be variously modified without departing from the gist thereof.
