BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a mounting component fixing structure for mounting and fixing a mounting component mounted on a housing of an electronic device.

[0002]

2. Description of the Related Art In a conventional mounting component fixing structure employed in telephones, intercoms and the like, as shown in FIGS. 4 (a) and 4 (b), various electronic components 1 are mounted on a substrate 2, and Is mounted on the housing 3 such as a knob for operating the electronic component 1 or a window material or the like for confirming an electronic component visually confirmed from outside the housing, such as an LED. It is attached to a hole 40 formed in the body 3.

A mounting component 50 shown in FIG. 4B is a window material for confirming the LED 1 as an electronic component from outside the housing 3. The mounting component 50 has a mounting portion 51 that is mounted in the hole 40 formed in the housing 3 and a protruding portion 52 that protrudes laterally and is locked by a protrusion 70 described later. As shown in FIGS. 4A and 4B, the fixing structure has a hole 40 formed in the housing 3 and a claw 61 protruding from the housing inner surface 31 into the housing around the hole 40. A pair of high protrusions 60,
60 and low protruding portions 70, 70 at positions substantially orthogonal to the high protruding portions 60, 60.

In order to mount the mounting component 50 in the hole 40 of the housing, as shown in FIGS. 5 (a) and 5 (b), the position is adjusted so that the mounting portion 51 fits into the hole 40. While claws 6
This is performed while pushing a pair of high protruding portions 60 each having 1 on both sides. When the overhanging portion 52 that protrudes beside the mounting component 50 comes into contact with the low protrusion 70, the mounting portion 5
1 is fitted in the hole 40, and the claws 61, 61 of the pair of high protrusions 60, 60 sandwich and fix the mounting component 50 from above both.

[0005]

In the above-described conventional mounting component fixing structure, since the mounting component is mounted while the pair of high projections 60, 60 are being pushed and spread to both sides, the bending of the high projection 60 returns. In addition to the large recoil, it is difficult to mount, and the positioning of the mounting portion 51 with respect to the hole 40 is difficult.

[0006]

An object of the present invention is to solve the above-mentioned conventional problems, and to provide a mounting component fixing structure that allows easy and smooth positioning when mounting a mounting component in a hole of a housing. With the goal.

[0007]

According to the present invention, there is provided a mounting component fixing structure for mounting a mounting component to be mounted in a hole formed in a housing of an electronic device which covers a substrate on which the electronic component is mounted. A guide which is a component fixing structure, and which serves as a guide for mounting a mounting component on a protrusion projecting from the inner surface of the housing and supporting the mounting component while tilting the mounting component with respect to the inner surface of the housing on which the mounting component is mounted. Part is provided.

[0008]

According to the present invention, a guide portion is provided on a projection projecting from an inner surface of a housing to support a mounting component, and serves as a guide for mounting the mounting component while inclining the mounting component with respect to the inner surface of the housing on which the mounting component is mounted. Therefore, the mounting component is guided and mounted by the guide portion, and is positioned in the hole formed in the housing, and the projection supporting the mounting component is hardly bent.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a mounting component fixing structure according to the present invention. In the mounting component fixing structure according to the present invention employed in telephones, intercoms, and the like, as shown in FIGS. 1A and 1B, various electronic components 1 are mounted on a substrate 2, and the substrate 2 is Protected by
And a knob for operating the electronic component 1 or L
A mounting component 5 such as a window material for confirming an electronic component visually confirmed from the outside of the housing, such as an ED, is mounted in a hole 4 formed in the housing 3.

A mounting component 5 shown in FIG. 1B is a window material for confirming the LED 1 as an electronic component from outside the housing 3. The mounting component 5 has a mounting portion 51 that is mounted in the hole 4 formed in the housing 3, and a protruding portion 52 that protrudes laterally and is locked by a protrusion 7 described below. Fig. 1
As shown in (a) and (b), a pair of high protrusions having a hole 4 formed in the housing 3 and a claw 61 protruding from the housing inner surface 31 into the housing around the hole 4. 6, 6 and low protruding parts 7, 7 located at a position substantially orthogonal to the high protruding parts 6, 6, the high protruding parts 6, 6 and the low protruding parts 7, 7
Are provided with notches 6a, 6a, 7a, 7 serving as guide portions for guiding the mounting part 5 while mounting it inclining.
a 'is provided. Notches 6a, 6a are provided in the same direction of the pair of high protrusions 6, 6, respectively (FIG. 1 (a)),
In the low protruding portion 7, a notch 7a is provided in at least the low protruding portion 6 on the side facing the notches 6a, 6a of the high protruding portions 6, 6 (FIGS. 1A and 1B). Another low protrusion 7
It is also preferable to provide a notch 7a '(FIG. 1B).

The shape, angle, size, etc. of the notches 6a and 7a are preferably selected in relation to the hole 4, the mounting portion 51, the high protrusion 6, and the low protrusion 7. To mount the mounting component 5 in the hole 4 of the housing, as shown in FIGS. 2A and 2B, the mounting component 5 is mounted while being inclined with respect to the housing inner surface 31 on which the mounting component 5 is mounted. The part 51 is notched 6a, 6
a, 7a, so that they are brought into contact with each other and slipped in at first, and then gradually upright. When the projecting portion 52 projecting laterally of the mounting component 5 comes into contact with the low protrusion 7, the mounting portion 51 is fitted into the hole 4, and the pair of high protrusions 6, the claws 61 of the high protrusion 6, 61. Are fixed by sandwiching the mounting part 5 from both sides.

As shown in FIG. 3, as a mounting component, a switch button 5 'for operating the switch 1' from the outside of the housing 3, and other suitable cases are similarly applicable.

[0013]

As is apparent from the above embodiments, the mounting component fixing structure according to the present invention is mounted in a hole formed in a housing of an electronic device which covers a substrate on which an electronic component is mounted. Mounting part fixing structure for fixing the mounting part,
The protrusion that is provided on the inner surface of the housing and supports the mounting component has a guide portion that guides the mounting component while tilting it with respect to the inner surface of the housing where the mounting component is mounted. The components are guided by the guides to facilitate positioning, and are easily mounted in the holes of the housing without substantially bending the projections supporting the mounted components.
