[Problems to be solved by the invention]
In the conventional interphone switch mounting structure, a slide rib 52 for sliding the slide knob 37 is provided in the lower housing 51, and the slide knob 37 mounted on the slide rib 52 is downwardly moved in FIG. The pressing rib 53 is necessary for pressing, and the pressing rib 53 opposed to the sliding rib 52 of the lower casing 51 is provided on the upper casing 50.
[0004]
Furthermore, there is a difficulty in that the distal end portion 36 of the slide knob 37 is disposed only at the joint portion between the upper housing 50 and the lower housing 51.
[0005]
The present invention has been made in order to solve these problems, and has a simple structure for pressing, can be surely pressed, and is not limited to the joint portion of the front and rear housings. The intercom switch can be used with a slide knob. An object is to provide a mounting structure.
[0006]
[Means for Solving the Problems]
Switch attachment structure of the interphone of the present invention in order to solve the above problems is to mount the substrate on which the electronic components and at least the slide switch is mounted includes a slide switch interphone front casing, between rear case, rear case Has an elastic rib for locking the slide knob for operating the slide switch in the lower direction of the rear case , and the slide knob is slidably fitted between the inner wall of the rear case and the elastic rib. The slide knob has a fitting groove for fitting the switch operating portion of the slide switch.
[0007]
In the interphone switch mounting structure according to the present invention, the rear case has a guideline for inserting the slide knob.
[0008]
According to such an interphone switch mounting structure, the interphone switch mounting structure is obtained, which is not limited to the joint portion between the front housing and the rear housing, and the structure for pressing is simple and can be surely pressed. .
[0009]
[Form of the present invention]
The interphone switch mounting structure according to the present invention will be described below in detail with reference to the drawings.
[0010]
As shown in FIG. 2, according to the present invention, in an interphone provided with a speaker 31, a microphone 32, and a CRT 33, a slide switch 3 for adjusting the ringing sound of the speaker 31 and the brightness of the CRT 33 when the interphone is installed (FIG. 2). 1) is related to the switch mounting structure of the interphone for mounting to the housing 5.
[0011]
As shown in FIG. 1, an electronic component 30 including a slide switch 3 of an interphone and a substrate 4 on which at least the slide switch 3 is mounted are mounted between a front casing 5a and a rear casing 5b .
[0012]
A switch operation unit 8 extends from the slide switch 3, and the switch operation unit 8 is fixed to the slide knob 1 as described later.
[0013]
The slide knob 1 has a fitting groove 17 for locking in the y direction by fitting the switch operating portion 8 of the slide switch 3 mounted on the substrate 4 of the electronic device. In the extending direction 17, an external operation unit 11 (FIG. 2) that adjusts the ringing sound of the speaker 31 and the brightness of the CRT 33 when the interphone is installed is extended.
[0014]
As shown in FIG. 1, the inner wall 9 of the rear housing 5b is provided with a guideline 6 for inserting the slide knob 1 from above. The guide line 6 is engraved as a shallow groove on the inner wall 9, but it is also preferable to draw a line. The guide line 6 is used for positioning the external operation unit 11 of the slide knob 1.
[0015]
A slide hole 7 through which the external operation portion 11 of the slide knob 1 is inserted and slid is formed at the end of the guide line 6.
[0016]
The rear casing 5b is provided with an elastic rib 2 standing in parallel with the inner wall 9 for locking the slide knob 1 in the lower direction x1 of the rear casing 5b and pushing the external operation portion 11 into the slide hole 7. The slide knob 1 is slidably fitted between the inner wall 9 of the rear housing 5 b and the elastic rib 2.
[0017]
The operation of the interphone switch mounting structure configured as described above will be described below.
[0018]
The slide knob 1 is inserted along the guideline 6 on the inner wall 9 of the rear housing 5b . At this time, the elastic rib 2 of the rear housing 5b is expanded in the x2 direction, and the slide knob 1 can be pushed in. When the slide knob 1 is fitted into the rear casing 5b , the elastic rib 2 returns to its original position, and the slide knob 1 is locked in the x1 direction.
[0019]
Next, the substrate 4 of the electronic device on which the slide switch 3 is mounted is disposed in the housing 5, and the switch operating portion 8 of the slide switch 3 is fitted into the fitting groove 17 of the slide knob 1. Further, the slide knob 1 is locked in the y direction by the switch operating portion 8 by screwing the substrate 4 to the housing 5 (not shown).
[0020]
The slide switch 3 set as described above is used to operate the external operation unit 11 viewed from the slide hole 7 of the rear housing 5b to the outside of the housing 5, and to adjust the CRT brightness of the interphone and the volume of the speaker as desired. Can be set to state.
[0021]
【The invention's effect】
As is apparent from the above description, according to the interphone switch mounting structure of the present invention, the electronic component including the interphone slide switch and at least the board on which the slide switch is mounted are mounted between the front casing and the rear casing. , rear case has a resilient rib for locking the slide knob for operating the slide switch to the rear casing downwards, sliding the slide knob between the inner wall and the elastic rib rear case The slide knob has a fitting groove for fitting the switch operation part of the slide switch, and the rear housing has a guideline for inserting the slide knob, so the structure is simple. It is possible to reliably hold the slide, and the slide knob can be used without being limited to the joint portion of the front and rear housings .
