Description

Operating panel assembly with integrated function selection switch and button

The present invention relates to an operating panel assembly that can be assembled simply and quickly when assembling a product by assembling a function mounting button and a PCB mounted with a switch controlled by the button into one.

[0003] In general, electric and electronic products such as various home appliances are provided with convenient function selection buttons for selectively controlling necessary functions. This function selection button is mainly installed in front of the switch controlled by the operation of the button.

As an example, if you look at the television receiver, you can see that various buttons such as volume up / down button, channel switch button, or video / audio select button are collectively installed at the bottom of the front panel. It allows you to control the functions you need from anywhere. The place where a plurality of buttons are arranged in this way is called an operating panel. Various buttons disposed on the operating panel are provided with buttons for controlling common functions in most products except for products having special functions.

As described above, the various function selection buttons arranged on the television receiver are fixed to the rear of the switch. The switches are soldered onto a printed circuit board (hereinafter referred to as an auxiliary PCB) having a relatively small area.

Therefore, it is difficult to control the switch directly by hand because the switch disposed on the PCB adopts a so-called small switch called a contact switch or a touch switch. Thus, the buttons are used to control the switches from the outside. Since the switch is very small, it is mainly employed in compact products having a small volume and a small space.

As described above, an example of assembling the buttons for operating the switches will be briefly described with reference to the accompanying drawings.

1 is a cross-sectional view showing an assembly relationship between a conventional function control button and a switch, in which reference numeral 10 is a function selection button assembly, 20 is a switch controlled by a function selection button, and 30 is a function selection button. 10 and the outer case of the product to which the switch 20 is coupled.

The function selection button assembly 100 has a fixing part 11 coupled to the boss 30a protruding from the inner surface of the case 30, and the PCB 40 is superimposed on the fixing part 11. The furnace screw is fastened to the boss 30a. And the tension portion 15 is extended from the fixing portion 11 is connected to the push button 10 is installed, the elastic force is inherent to return the push button to its original position. The push button 12 is provided with the pressing pin 13 which presses the on-off contact of the switch 20 in the back.

The front of the case 30 of the product is arranged with holes in which the push button 10 is movably positioned on the surface for installation so that the push buttons can be operated.

As can be seen from the above, in the conventional structure of the push button 10 and the switch 20, the fixing part 11 of the push button 10 and the PCB (using a screw inside the case 30); 40 is fixed by fastening to the boss 30a, so that the assembly time is relatively large and inconvenient, and the push button 10 that does not fit into the hole of the case 30 has a problem in that it cannot be assembled. In particular, the model of a specific product may be produced by diversifying a series of products according to functional status, a change in design form, or a color of the product to broadly accommodate a consumer's desire to purchase. In this case, the number of function selection buttons may be increased or decreased depending on the presence or absence of a function, and the space for installing the buttons may be wider or narrower. Therefore, even in the case of a series of products, each case of the product can not only be manufactured separately, which increases the manufacturing cost of the case, and the push button 10 must also be newly manufactured to fit the case, as described above. And assembly of PCBs with switches has been problematic.

As part of solving the problems described above, when manufacturing a function selection button recently, a plurality of push buttons 10 are manufactured to be integrated and combined at a time so that the assembly process that has been assembled several times may be relatively simple. However, a button assembly made so that a plurality of buttons are installed in one body is also almost incompatible with other models.

Therefore, in the case of products equipped with switches and buttons that perform the necessary functions in common, although there are differences in size or small as homogeneous products, the diversification of the products can be achieved when the various function buttons are used interchangeably. This can be achieved, and the effect of reducing the mold manufacturing cost according to the case can be expected.

The present invention has been made in order to solve the problems described above, the main object of the present invention is to provide an operating panel assembly that can be easily assembled to the case by pre-assembling the push button and the switch to the case easy to assemble To provide.

Another object of the present invention is to assemble a function selection button and a switch so that the operating panel of the same product and the buttons assembled on the panel can be used interchangeably with each other. To provide a panel assembly.

Another object of the present invention is to configure the space portion when manufacturing the case in which the operating panel is installed by assembling the operating panel in the space there is an effect of simplifying the production of each case and reducing the production cost, It is possible to change the adoption of the product to provide an effect that can be diversified.

The operating panel assembly incorporating a switch and a button for operating a switch according to the object of the present invention, in assembling a PCB on which a switch for controlling a function of a product and a button for controlling the switch, has a predetermined space at a specific position. A case of a product which is cut out to constitute a space part; At least one switch is disposed and has a plurality of fastening holes; A button assembly having a plurality of push buttons having a tension part connected to the body and a pressing pin for pressing the switch on the back of the push button, the button assembly being detachably coupled to the PCB by a hook and controlling the switch; Comprising the engaging ring coupled to the inner surface of the space portion and the coupling hole to the push button of the PCB protrudingly coupled to cover the space of the case, consisting of an operating panel detachably coupled to the PCB by the hook Can be achieved.

According to the configuration of the present invention, the present invention can be assembled without using a component such as a screw by assembling the button assembly and the PCB to the operating panel integrally to the case, and also the button and the PCB on the operating panel Since it is assembled integrally, if the operating panel assembled integrally is installed in the space of the case, the button assembly and the PCB can be mounted at the same time. In addition, the manufacturing cost can be reduced by manufacturing the case to penetrate the space where the operating panel is mounted when manufacturing the case, and also it is possible to diversify the product by changing the assembly of the button assembly assembled to the operating panel. .
