Description
The present invention relates to a remote control side push button having an automatic return function. More specifically, in various small electronic apparatuses including a remote controller, a button installed in a side direction rather than a side of a PCB has a simple structure, To a remote control side push button having an automatic return function which is developed in order to secure feeling and durability.
A small electronic apparatus including a remote controller and a cellular phone for wirelessly operating various electronic products including a TV includes a plurality of buttons on an upper surface thereof and has an upper convex contact plate on the upper surface of the PCB, It is general that the contact plate is pressed so as to be closely energized with the contact point of the PCB.
The structure called pushbutton or switch has a relatively simple structure and operates by a force acting perpendicular to the PCB, which is advantageous in that a plurality of buttons can be freely formed on one PCB.
However, many of the remote controls have a switch on the side, but they are not tangent to the PCB surface, so they are usually small boxes called tact switches with push buttons on one side and lead wires for electrical connection It is common to use switches.
Tektoswitches can be misaligned when assembled on a PCB, or when the foreign substance penetrates, the operating force becomes too weak or strong. In other words, the feel of the hand touching the switch may be weak or strong.
Particularly, when the operating force is weak, the elasticity of the internal parts (contacts) is weakened due to repetitive use, and when the foreign matter penetrates, there is a failure that the operating force becomes strong. And it has a disadvantage that it has a large influence on the quality because it is made unstable or unstable.
This problem is caused by the fact that the TEXT switch is used when a power button or a small number of input buttons of a home appliance and a computer are applied, but it does not apply to a top button occupying most of the remote control buttons. However, due to its position relative to the PCB, The switch is being used.
However, Tektoswitch, which is manufactured by a separate manufacturer, causes various price disadvantages and increases the unit price. Therefore, it is necessary to develop a button that can be applied to the side with a stable operation force and a durable structure.
SUMMARY OF THE INVENTION The present invention has been developed in order to solve the above-mentioned problems, and its object is to provide a remote controller having a stable and durable automatic return function, in which a button used on a side surface of a remote controller is quickly and rapidly rotated after a separate pressing operation, Button.
According to an aspect of the present invention, there is provided an electronic device including a bottom case and an upper case, the bottom case and the top case being coupled to each other by a built-in PCB, A guide protrusion which protrudes upward from a bottom surface of the guide hole and a guide protrusion which protrudes upward from the bottom of the guide hole; An upper pressurizing fixing part protruding downward from an end of the hole so as to be in close contact with a bottom surface of the PCB, an upper pressurizing fixing part protruding downward from the upper case to closely contact with the upper surface of the PCB, And a contact plate which is mounted with a convex shape to the lower portion and makes electrical contact when the upper portion is pressed, A cone body;
And the other side of the button is exposed through the button-exposing hole, and the other side of the button-releasing protrusion extends in such a manner that the outer surface thereof has a larger cross-section than the button-exposing hole. A button body including an inclined surface extending obliquely upwardly and a sliding portion having an upper end having a pushing portion for pressing the contact plate when the inclined surface is raised in close contact with the guide projection;
And an elastic member inserted between the lower pressing and fixing part and the sliding part to have an elastic restoring force.
In addition, the elastic member is made of a rubber material having an elastic restoring force, and has two stepped portions whose outer diameters are reduced stepwise in the direction of the sliding portion, and the inner portion is opened in the direction of the lower pressing and fixing portion.
Further, the lower pressing and fixing unit may further include an elongated hole cut vertically and vertically, and a cutting hole communicating with the guide hole vertically cut from one side of the elongated hole;
And an end of the compression coil spring inserted into the elastic member and exposed to the opened portion is inserted and fixed from the upper portion through the long hole and the cut hole.
As described above, according to the present invention, when the button body is pressed, the other side presses the contact plate formed on the bottom surface of the PCB by the guide protrusion so as to make electrical contact and is quickly pushed back by the elastic member having the elastic restoring force It has good feeling with stable operating force and has a simple structure, which is low in manufacturing cost and has durability.
