DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure of a push button arranged on an operation section of an electronic device, for example, a television receiver.

[0002]

2. Description of the Related Art Conventionally, as a push button device, for example, one described in Japanese Utility Model Publication No. 7-9418 is known. FIG. 4 is a side sectional view of a conventional push button device. The mounting structure of the push button in FIG. 4 is such that the push button 42 is mounted and fixed to the housing 41 with the stop screw 43. A switch 44 and a printed board 45 are provided below the housing 41.
Is installed.

[0003]

In the conventional push button device, the push button 42 is attached to the housing 41.
The printed board 45 is positioned independently of the housing. Therefore, when the dimensional errors and the mounting errors of the components are integrated, the positional accuracy of the center of the switch pressing portion 46 of the push button 42 and the center of the switch 44 arranged on the printed board 45 is sufficiently maintained. Not done. As a result, there have been observed such phenomena that the pressing portion 46 is disengaged from the switch 44 when the push button is pressed, and the clearance between the pressing portion 46 and the switch 44 cannot be kept constant, so that a desired operation cannot be performed. Further, when fixing the push button 42 to the housing 41, it is necessary to use a plurality of screws 43.

[0004]

In order to solve the above-mentioned problems, a mounting structure for a series of push buttons according to the present invention comprises a plurality of push buttons connected to pins and ribs protruding from an inner surface of a housing. The hole provided in the connection part of the push button series and the end of the rib are respectively inserted, and further, the end of the printed board is inserted and fitted in the slit of the rib provided in the connection part of the button series, thereby forming the button. The switch pressing portion provided in a row and the plurality of switches arranged on the printed board are fixed so as to correspond to each other.

[0005] With the above configuration, the displacement between the switch pressing portion of the series of push buttons and the plate switch mounted on the print is eliminated, and the clearance (gap) between the switch pressing portion and the switch can be kept constant. Further, the push button sequence can be fixed to the housing without using screws.

[0006]

This will be described with reference to FIG.

(Embodiment) FIG. 1 is an exploded perspective view of a main part of a push button mounting structure according to an embodiment of the present invention.
2 is a plan view of a main part of FIG. 1, and FIG. 3 is a sectional view of a main part of FIG.

In FIG. 1 to FIG. 3, reference numeral 1 denotes a series of push buttons provided with a plurality of push buttons, 2 denotes a step-like connecting portion for integrally connecting a plurality of push buttons, and 3 denotes a connecting portion provided on the connecting portion. One rib, 4 is a second rib provided on the connecting portion, 5 is a housing (for example, a front housing constituting a television receiver),
Reference numeral 6 denotes a positioning rib protruding from the inner surface of the housing, 7 denotes a guide rib protruding from the inner surface of the housing, 8 denotes a positioning pin protruding from the inner surface of the housing, and 9 denotes a positioning rib. The first slit provided, 10 is a second slit provided in the second rib, 11 is a fitting hole formed in the connecting portion, 12 is a switch pressing portion, and 13 is a printed wiring board on which a switch is mounted. (Printed board), 14 is a switch, 1
Reference numeral 5 denotes a third slit provided on the printed board, and reference numeral 16 denotes a through hole provided on the front surface of the housing.

[0010] The mounting structure of the push button series according to the present invention comprises a step-like connecting portion 2 for connecting a plurality of push buttons.
A push button sequence 1 having a first rib 3 and a second rib 4 that reinforce the connecting portion 2 and have a second slit 10 and a plurality of switches 14 corresponding to the plurality of push buttons. A housing having a printed board 13 mounted thereon and a plurality of through holes 16 through which the push button is inserted in a side wall, and guide ribs 7, positioning pins 8, and positioning ribs 6 protruding from the inner surface of the side wall. And a fitting hole 11 provided in the connecting portion 2 of the push button series 1 is fitted into a positioning pin 8 of the housing 5, and further, a positioning rib 6 of the positioning rib 6 provided in the housing 5 is provided. The end of the first rib 3 of the push button train 1 is inserted into the first slit 9, and the second slit 10 provided in the second rib 4 of the push button train 1 is further inserted.
