Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a remote control side push button having an automatic return function,

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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown.

FIG. 1 is a conceptual diagram according to an embodiment of the present invention. FIG. 2 is a conceptual diagram illustrating a state in which a button body according to an embodiment of the present invention is separated. FIG. 3 is a perspective view illustrating a pushing operation according to an embodiment of the present invention. FIG. 4 is a conceptual view depicting a pressed state according to an embodiment of the present invention. The lower case 11 and the upper case 12 have a PCB 13 built in and connected to the inside, A button exposing hole 111 through which the outside and the inside space communicate with each other, a guide extension 112 extending inwardly from the upper and lower sides of the button exposure hole 111, A guide protrusion 114 protruding upward from a bottom surface of the guide hole 113 and a guide protrusion 114 protruding upward from a bottom surface of the guide hole 113 And is closely contacted with the bottom surface of the PCB 13 An upper pressing and fixing part 116 protruding downward from the upper case 12 to come into close contact with the upper surface of the PCB 13 and a lower pressing and fixing part 116 which is protruded downward from the upper case 12, And a contact plate (117) mounted on the bottom surface of the main body (1) so as to have a downwardly convex shape so as to make electrical contact when the upper part is pressed.

(21) which extends through the button-exposing hole (111) to expose the other end of the button, and the other end of the button-receiving hole (111) has a larger cross section than the button-exposing hole (111) The inclined surface 221 is inserted through the hole 113 and extends obliquely upward toward the lower end and the upper end is pressed against the contact plate 117 when the inclined surface 221 is raised in close contact with the guide protrusion 114 A button body (2) including a sliding portion (22) having a raised portion (222) for allowing the button body

And an elastic member 3 inserted between the lower pressing and fixing part 115 and the sliding part 22 to have an elastic restoring force.

In this embodiment, the button body 2 has a structure that prevents the release button 21 from being released after assembly by the release preventing protrusion 21 so that the button body 2 can be operated by the contact plate 117 like the push button previously formed on the upper surface. So that the force to be projected by the member 3 always acts.

When the user pushes the protruded button body 2, the sliding part 22 enters the inside and the guide protrusion 114 and the inclined surface 221 are brought into close contact with each other so that the upper lift part 222 of the sliding part 22 contacts the contact plate The button body 2 is slightly rotated as a whole.

The elastic member 3 pushes the button body 2 outward and the contact state by the contact plate 117 is released.

5 is a bottom perspective view showing an elastic member according to an embodiment of the present invention. The elastic member 3 is made of a rubber material having an elastic restoring force and has two And the inner side is opened in the direction of the lower pressing and fixing part 115 with the step portion 31. [

Although the elastic member 3 may be made of various kinds of spring or rubber materials, the shape of the elastic member 3 according to the present invention may initially enter the inside without great resistance when the button body 2 is pressed, So that the elastic restoring force can be increased as the compression of the elastic member 3 is progressed.

With this structure, since the initial restoring force is strong after the pressing, the returning of the button body 2 is performed quickly, so that it is possible to press the button body 2 at a high speed continuously and to increase the feeling of use.
