BACKGROUND OF THE INVENTION
The present invention relates to a rotary electronic component with a push button switch in which a rotary electronic component such as a rotary switch is provided with a function of a push button switch.
[0002]
[Prior art]
Conventionally, a rotary electronic component with a pushbutton switch has been developed, in which the switch is switched by rotating a knob of the rotary switch, and another pushbutton switch is turned on and off by pressing this knob in the radial direction. in use.
[0003]
This type of rotary electronic component with a pushbutton switch is used, for example, as a menu selection / setting switch for a mobile phone, a manual focus adjustment / setting switch for a video camera, an iris adjustment / setting switch for a camera, and the like. That is, in the case of a mobile phone, for example, the menu is selected by rotating the knob, and the menu is set by pressing the knob in the radial direction in that state.
[0004]
The applicant of the present application has developed such a rotary electronic component with a push button switch as shown in FIG. As shown in the figure, this rotary electronic component with a pushbutton switch has a knob 230 fixed to a protrusion 211 provided on the slide member 210 so that the knob 230 can rotate, and is attached to a flexible substrate 250 attached to the surface of the slide member 210. The attached slider 240 is brought into contact, and the click portion 269 of the click plate 260 attached to the tip of the protrusion 211 is engaged with the click recess 235 provided on the knob 230, and provided on the outside of the slide member 210. A leaf spring 270 bent in a “<” shape is housed in the spring housing portion 217, and a pressing portion 271 at the center of the leaf spring 270 is brought into contact with the switch contact 281 provided on the support plate 290, and at the same time, the upper and lower ends The stop portions 273 and 275 are configured to contact a predetermined portion of the push button case 295 fixed to the slide member 210 and the support plate 290. That.
[0005]
When the knob 230 is rotated, the slider 240 slides on the switch pattern 253 provided on the flexible substrate 250, and a desired output is obtained. On the other hand, if the knob 230 is pressed in the direction of the arrow a, the slide member 210 is also slid together with this, and the leaf spring 270 is bent, so that the pressing portion 271 protrudes toward the switch contact 281 and turns on. .
[0006]
By the way, the above-mentioned rotary electronic component with a push button switch was invented to reduce the size and thickness of the electronic device. However, in order to further reduce the size and thickness of portable devices, the size and thickness of the portable device are further reduced. Is required. In particular, the portion in which the leaf spring 270 is housed is a portion that enters the inside of the portable device, and therefore, the height is required to be shortened.
[0007]
However, since the leaf spring 270 has a “<” shape and is relatively long, it is difficult to further reduce its height (length).
[0008]
[Problems to be solved by the invention]
The present invention has been made in view of the above points, and an object of the present invention is to provide a rotary electronic component with a pushbutton switch that can be further downsized in the height direction (sliding direction) compared to the conventional art.

The pressing arm 73 and the pivot support arms 77 and 77 are bent by a predetermined angle in the opposite direction at the upper side of the switch pressing portion 71 (side on the rotary switch A side). That is, the pressing arm 73 and the pivot support arm 77 are formed to open at a predetermined angle (preferably an acute angle).
[0018]
Next, the flexible substrate 50 has a substantially circular shape and is provided with a hole 51 having a dimension penetrating the protrusion 11 of the slide member 10 at the center, and a desired switch pattern 53 is formed on the front surface of FIG. Yes. On the other hand, the flexible substrate 80 is provided with a switch contact 81 to which a click plate 82 made of a dome-shaped elastic metal plate is attached at the center of the surface, and attachment holes 85 and 85 are provided on both sides thereof. The flexible substrate 50 and the flexible substrate 80 are connected by a connecting portion 87 and are drawn out from a drawer portion 89.
[0019]
The support plate 90 is made of a metal plate in this embodiment, and a locking portion 91 formed of a T-shaped hole for inserting and locking the locking protrusion 18 of the slide member 10 is provided in the vicinity of the upper portion thereof. Two claw-shaped locking portions 93, 93 are provided in parallel at the center, and mounting holes 94, 94 are also provided at positions corresponding to the mounting holes 85, 85 on both lower sides thereof.
[0020]
To assemble the rotary switch with the pushbutton switch, first, the flexible substrate 50 shown in FIG. 3 is placed on the base 13 of the slide member 10 as shown in FIG. Then, the protrusion 11 of the slide member 10 is inserted into the hole 31 of the knob 30 to which the slider 40 is fixed, and the small protrusion 12 at the tip of the protrusion 11 is fitted into the through hole 63 of the click plate 60 to Crimp the tip. This prevents the knob 30 from coming off, and at the same time, the sliding contact portion 41 at the tip of the slider 40 is pressed against the switch pattern 53 of the flexible substrate 50 to be elastically contacted. As a result, the state shown in FIG. 2 is obtained.
[0021]
On the other hand, the flexible substrate 80 is placed under the support plate 90, and the switch operating member 70 is placed thereon. At this time, the two shaft support portions 79, 79 of the switch operating member 70 are hooked on the locking portions 93, 93 of the support plate 90.
[0022]
The slide member 10 to which the knob 30 is attached is placed on the support plate 90. At this time, the locking protrusion 18 of the slide member 10 is inserted into the locking portion 91 of the support plate 90 and moved downward. To lock. At this time, as shown in FIG. 1, the pressing portion 75 of the switch operating member 70 contacts the contact portion 21 of the slide member 10. Then, a push button case 95 is put on the slide guide portion 17 of the slide member 10, and at this time, the locking portions 98, 98 are inserted into the slide restricting recesses 23, 23, the mounting holes 85, 85, and the mounting holes 95, 95. Then, heat crimping is performed on the back surface of the support plate 90. This completes the rotary switch with pushbutton switch shown in FIG. At this time, the switch pressing portion 71 of the switch actuating member 70 is in contact with the switch contact 81 as shown in FIG.
[0023]
When the knob 30 is rotated, the sliding contact portion 41 of the slider 40 slides on the switch pattern 53 of the flexible substrate 50 to change its output, and at the same time, the click portions 69 and 69 of the click plate 60 are moved to the knob 30. A click sensation is generated by disengaging from the click uneven portion 35.
[0024]
On the other hand, when the knob 30 is pressed in the radial direction (arrow C direction (sliding direction)), the slide member 10 is lowered together with the knob 30 and the like, and the pressing portion 75 of the switch operating member 70 is pushed down by the contact portion 21 of the slide member 10. Therefore, the switch actuating member 70 tries to rotate around the shaft support portions 79 and 79, and as a result, the switch pressing portion 71 presses the switch contact 81 to reverse it and turn it on. If the pressing of the knob 30 is released, the click plate 82 and the switch operating member 70 are automatically returned to their original positions, and the switch contact 81 is turned off. The vertical movement of the slide member 10 is restricted by the locking portions 98 and 98 that engage with the slide restriction recesses 23 and 23 of the slide member 10.
[0025]
