Description

Switch board of electronics {SWITCH BOARD OF ELECTRONIC MANUFACTURED GOODS}

The present invention relates to a switch board of an electronic product, and more particularly, to a switch board of an electronic product that has a good feeling of switch operation and can maintain a switching function without fear of malfunction even when used for a long time.

In general, electronic products are provided with a plurality of power and function switches for turning on and off power, selecting and adjusting various functions, and these switches are made as light and thin as possible for miniaturization of electronic products.

4 is a cross-sectional structural view showing a conventional switch board used in electronic products, in which several switch pattern portions 2 are arranged on a substrate 1, and each switch pattern portion 2 has three contact points. Have (3) Then, a spacer 5 having a through hole 4 formed at a portion where each switch pattern portion 2 is positioned is attached to the substrate 1, and the conductive plate 6 and the cover sheet 7 are formed on the spacer 5. ) Are attached one after another.

In addition, a conductive connection pad 8 is attached to the bottom surface of the conductive plate 6 facing each switch pattern portion 2, and the connection pad 8 is formed by the thickness of the spacer 5. It is arranged to be maintained at a constant interval with the contact (3) of.

On the surface of the cover sheet 7 in which each switch pattern portion 2 is located, a letter or a figure for the corresponding function is displayed. Accordingly, as shown in FIG. 6, the cover sheet 7 is pressed into the space formed by the through hole 4 of the spacer 5 by pressing the corresponding portion of the cover sheet 7 in which the desired function is displayed. The connection pad 8 is lowered to come into contact with the three contacts 3 of the switch pattern unit 2, whereby the switch signal is transmitted to a controller of an electronic product (not shown) to perform a corresponding function. Subsequently, when the user releases the held hand, the cover sheet 7 is restored by the self-elastic force, so that the connection pad 8 is also in the original position and is spaced apart from the contact 3 of the switch pattern portion 2 so that the three contacts 3 are short-circuited again. It becomes a state.

In the conventional switch board configured as described above, as shown in FIG. 6, when the cover sheet 7 is pressed, the connection pad 8 is pressed by the cover sheet 7 being pressed into the through-hole 4 of the spacer 5. Since the switch operation is made by lowering, when pressed slightly, the connection pad 8 may not be in contact with the contact point 3 of the switch pattern portion 2 and thus the switch operation may not be performed. Therefore, the user is conscious of this and presses with more force than necessary.

In this way, it is difficult to sense sensibly how hard to operate the conventional switch board. Therefore, when pressing too weakly, there is a possibility that the function does not work, and if pressing too hard unnecessarily, the force is put on the fingertips, there is a disadvantage that the operation feeling is bad.

In addition, when using electronic products, only the switch portion is repeatedly pressed, and the cover sheet 7 is made of a vinyl material, and thus, when used for a long time, the cover sheet 7 of the switch portion is extended, thereby increasing its elasticity in the increased switch portion. There is a risk of malfunction due to weakening.

The present invention is to solve the conventional problems as described above, the object is that the switch operation is made by the elastic deformation and elastic recovery of the connection terminal made of a metal material, the elastic deformation and elastic recovery of this connection terminal An electronic product that makes it possible to make a metallic sound at the time, which makes it possible to know that the switch operation was performed reliably by this metallic sound, and to improve the feeling of switching operation by not using unnecessary large force by the metallic sound. To provide a switch board.

In addition, the present invention is to provide a switch board of an electronic product that can maintain the self-elasticity of the connection terminal and there is no fear of malfunction even when using the electronic product for a long time.

The above object is an electronic product in which a switch pattern portion having three contacts is formed on a substrate, a spacer having a through hole formed in the switch pattern portion portion is attached to the substrate, and a cover sheet is attached to the spacer. In the switch board of the present invention, both ends of the switch pattern portion are connected to each other, and the center portion is curved in an arc shape from both ends, and a metal connecting terminal spaced apart from the center contact is provided in the through-hole of the spacer. It can be achieved by the switch board of the electronic product, characterized in that the contact with the three contacts in the elastic deformation position of the terminal, and spaced apart from the central contact in the elastic restoring position.

In addition, it is preferable that the connection terminal forms rectangular holes in both elastic deformation boundaries so as to facilitate elastic deformation and elastic recovery, and cutout grooves are formed in both edges of the elastic deformation boundary, respectively.

Hereinafter, the switch board of the present invention will be described in detail with reference to FIGS. 1 to 4. 1 and 2 illustrate a switch board for use in a microwave oven as an embodiment of the present invention, and a plurality of switch pattern portions 13 having three contacts 12 are disposed on a substrate 11. Each switch pattern unit 13 is connected to a control unit of a microwave oven (not shown) through the flexible substrate 14 to receive a switch signal of the switch pattern unit 13.

An insulating spacer 16 having a through hole 15 is attached to the switch pattern portion 13 on the substrate 11, and a thin cover sheet 17 of the insulating layer is attached to the spacer 16. On the surface of the cover sheet 17, various functions of the microwave oven are displayed in pictures or letters on the switch portion S in which the switch pattern portion 13 is located.

In addition, a space portion is formed between the contact 12 of the switch pattern portion 13 and the cover sheet 17 by the through hole 15 of the spacer 16, and the metal connecting terminal 18 is formed in the space portion. Is installed. The connection terminal 18 is to be elastically restored automatically after elastic deformation by self-elastic force, and both ends are connected to both contact points 12 of the switch pattern portion 13, and the center portion is curved in an arc shape from both ends. And spaced apart from the central contact 13. Therefore, as shown in FIG. 3, when the connecting terminal 13 is pressed and elastically deformed (virtual line state), the three contact points 12 of the switch pattern part 13 come into contact with each other, and the pressing force is removed to self-elastic restoring force. When it is returned to the original position (solid line state), the switch function can be performed by being spaced apart from the central contact point 12.

In this case, as shown in FIG. 4, the connection terminal 18 has rectangular holes 19 formed at both sides of the elastic deformation boundary so as to facilitate elastic deformation and elastic recovery, and cutout grooves are formed at both edges of the elastic deformation boundary. 20 are formed, respectively.

The present invention of such a configuration can be sensibly adjust the pressing force when operating the switch. That is, as shown in FIG. 3, when the switch part S is pressed, the metal contact terminal 18 is in contact with the three contacts 12 of the switch pattern part 13 while elastically deforming like a virtual line state. . At this time, the connection terminal 18 is elastically deformed and gives a "smart" metal sound, and the user recognizes that the three contacts 12 are connected by this metal sound, and presses unnecessaryly by removing the pressing force at that moment. There is no need to sustain the force or apply a greater pressing force. When the pressing force is removed, the connection terminal is restored to self-elasticity while producing a "metal" sound. Therefore, the switch operation feeling becomes very good by the elastic deformation and the metal sound of the connection terminal 18.

In addition, since the self-elasticity of the connection terminal 18 is maintained for a long time by repeatedly pressing the switch portion S, the self-elasticity of the connection terminal 18 can be maintained for a long time without fear of malfunction.

As described above, according to the switch board of the electronic product according to the present invention, when the connection part is pressed and the connection terminal is elastically deformed, it gives out a "squeaking" metal sound, thereby making sure that the switch operation was performed by this metal sound. At the same time, there is no need to continuously hold the pressing force or operate with a larger pressing force by this metal sound, thereby improving the switch operation feeling.

In addition, since the self-elasticity of the connection terminal lasts for a long time, there is no fear of malfunction when operating the switch even when using electronic products for a long time.
