Description

Pushbuttons for Fungi {.}

The present invention relates to a pushbutton switch inclined to the outer circumferential surface of the top of the reflector and the inner circumferential surface of the body so that the distance between the micro switch terminal and the terminal contact portion for pressing the terminal can be maintained at all times for extending the life of the switch and stabilizing the performance. In order to maintain the direction of the switch when mounting the stop, and to make a protruding round portion on the outer peripheral surface of the body, and also to prevent damage caused by interference fit during assembly of the body portion and the lamp holder portion, It relates to a push button made of a structure that prevents damage to the inner peripheral portion of the lower body portion and the outer peripheral portion of the lamp holder portion due to interference fit by placing an incision cut in the lower portion.

The pushbutton includes a knob 100, a filter 110, a reflector 120, a body 130, a lampholder 140, a micro switch 150, and a spring 160. In this case, the knob, the filter, and the reflector are positioned in the assembled state toward the body, and the lamp holder is assembled with the micro switch 150 at the bottom of the body, and the spring 160 is located between the reflector and the lamp holder. Make the reflector move to its original position. The knob and the filter reflector are integrally formed so that when the user presses the knob, the reflector moves to the lower side, and the terminal contact portion 122 at the bottom of the reflector presses the terminal 151 of the micro switch by a predetermined stroke for the micro switch. Was installed to work. When the micro switch is normally operated, a current flows through a light bulb (not shown) installed in the lamp holder 140, and the light passes through the filter 110 to be checked by the user's eye through a transparent knob. The operation process is completed. The operation process is a situation that usually occurs in the pushbutton, the description of the technical matters for the operation portion is omitted in the present invention.

In general, pushbutton switches are commonly used in electronic devices such as electronic entertainment. When the push button is used in an electronic entertainment machine, the reflector 120 is hit by thousands or tens of thousands of times per day, and thus, due to the shock vibration and the like, it is easily broken or damaged, and thus should be manufactured to be firm and stable. First, referring to the problems of the conventional push button, when referring to the issues related to the life and stability of use, the user presses the knob, the terminal contact portion 122 of the reflector contacts the terminal 151 of the micro switch. The force of is applied directly to the reflector, and the force immediately presses the terminal of the micro switch and simultaneously contacts the micro switch body so that the terminal contact portion of the reflector strongly strikes the upper surface 152 of the micro switch. In this case, the terminal contact part repeatedly hits the micro switch body repeatedly, causing damage and malfunction of the micro switch, causing spark on the switch itself, and thus causing a decrease in lifespan. In addition, when assembling the lamp holder 140 and the body 130 due to the assembly problem, the outer diameter of the lamp holder is slightly larger than the inner diameter of the body assembly portion to be assembled by fitting to fit, as described above, assembled by fit If the assembly process is difficult, in some cases it is more likely to cause damage to the lamp holder or the body portion during assembly, there is a possibility that the excessive load is applied to the body portion when used after assembly is damaged even during use. In addition, referring to a problem occurring when the pushbutton is mounted after use, when mounting the pushbutton on an amusement machine, a hole is drilled in the panel 10 to be mounted, and the pushbutton is inserted therein, and then a female screw member is provided at the bottom of the panel. (20) is fastened to the screw portion formed on the outer peripheral surface of the body to be mounted. At this time, if the push button is repeatedly hit by the pushing operation, the entire push button is rotated due to vibration and excessive load, and the screwing of the female screw member supporting the push button frequently occurs. If this situation is detected in a timely manner and the screw is tightened to its original state, it is fortunate, but if it is not detected in a timely manner, the push button may be damaged or malfunction, and eventually it may be broken and cannot be used.

The present invention proposes various solutions to solve the above-mentioned problems. First of all, an object of the present invention proposes a configuration in which the reflector terminal contact portion 122 can stop at a predetermined position when the reflector is moved to the lower side in order to improve the problem of the direct contact with the body of the micro switch. do. In addition, the present invention proposes a separate assembly structure in order to improve the problems caused by the body portion and the lamp holder portion fitting. In addition, the present invention proposes an anti-rotation structure to prevent the push button itself from rotating even when excessive load or vibration due to repeated pressing.

As described above, in order to solve that the terminal contact portion 122 of the reflector 120 damages the micro switch due to frequent contact with the main body of the micro switch, the external inclined stop is stopped on the upper outer circumferential surface of the reflector. A portion 121 is formed, and an inner sloping stop 131 corresponding to the outer sloping stop 121 is provided on the inner circumferential surface of the body 130. The inclined stops 121 and 131 play a role of the inclined stop 121 of the reflector when the reflector is moved downwards before the terminal contact 122 contacts the body 152 of the micro switch. It is in contact with the inclined stop 131 to prevent the reflector from lowering further down. When the reflector is stopped by the inclined stop, it is preferable to determine the position of the inclined stop so that the distance between the terminal contact portion 122 and the body of the micro switch 150 is maintained at 0.5 millimeter. The position of the inclined stop portion required to maintain the 0.5 mm is obvious that can be achieved at the technical level of those skilled in the art even if not mentioned in detail, the numerical technique is omitted in the present invention.

In addition, the present invention is provided with a cutout 134 at the bottom of the body portion to improve the overall problems caused by the interference between the lamp holder and the body portion mentioned above. In the conventional case, the convex fitting part 141 is provided on the outer circumferential surface of the lamp holder, and the concave fitting fixing part 132 corresponding to the convex fitting part 141 is provided on the inner circumferential surface of the body part. It is difficult to assemble by assembling, and at least one incision 134 on the circumference to be assembled with the lower lamp holder of the body as described above is difficult to assemble, excessive load is applied even after use. In addition, the assembly work can be facilitated, and the heavy load is distributed to the body and the lamp holder even when used after assembly, thereby preventing damage or damage due to the heavy load.

In addition, the present invention includes an anti-rotation protrusion 133 at the upper end portion of the screw portion of the body portion to prevent rotation of the push button caused by repeated pressing or vibration. The anti-rotation protrusion can keep the direction of the button because it can prevent the rotation of the push button when assembled in close contact with the panel 10, in particular, the shape of the knob need to maintain the direction, such as square, triangle, etc. Pushbuttons must have anti-rotation protrusions.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a mounting view of a push button according to the present invention, Figure 2 is an exploded perspective view of the push button, Figure 3 is a detailed view showing a contact state of the terminal contact portion 122 and the terminal portion 151, and Figure 4 Is a detailed view showing the assembly state of the lamp holder 140 and the body portion and includes at least one cut.

Figure 2 illustrates the structure of a push button proposed in the present invention. The pushbutton switch is divided into a knob 100, a filter 110, a reflector 120, a spring 160, a body 130, a lamp holder 140, and a micro switch 150 have. First, the contact state between the terminal contact portion 122 of the reflector and the terminal 151 of the micro switch unit will be described. When the user presses the knob 100, the reflector 120 integrally coupled with the knob moves to the lower end, and the terminal contact part 122 also moves to the lower side while pressing the terminal part in contact with the terminal part 151. At this time, the bottom surface 123 of the terminal contact portion is also moved to the lower side. Before the bottom surface is closed on the body 152 of the micro switch, the outer stop inclined portion 121 of the reflector is placed on the inner slope stop portion 131 of the body portion. The first contact is made and no longer moves to the bottom. 3 shows the movement distance "S1" of the bottom surface 123 of the terminal contact portion and the distance "S2" from the upper body 152 of the micro switch when the bottom surface 123 is moved to the maximum bottom. In the present invention, the distance "S2" between the bottom surface 123 and the micro switch upper body 152 when the terminal contact portion is lowered to the bottom is preferably maintained at about 0.5 millimeter, which means that the terminal 151 of the micro switch has an upper portion. This is because the normal operation is performed even when pressed by the "S2" interval from the body 152. "S2" is slightly different depending on the type of the micro-switch, which will be able to achieve the object through a few design changes within the technical scope of those skilled in the art, which will be within the scope of the technical idea of the present invention. 4 illustrates an assembly state of the lamp holder 140 and the body 130. As can be seen in the drawing, the lamp holder and the body portion are easy to assemble and, after assembly, the cutout portion 134 is provided at the bottom of the body to distribute the excessive load. The cutout has at least one, and the shape is dome-shaped. The shape of the cutout shows a dome shape, but may be provided in various shapes within the technical scope of those skilled in the art. 1 is provided with an anti-rotation protrusion 133 on an upper end of a body part to prevent the button from rotating due to excessive hitting or vibration, as the frequency of use of the pushbutton is increased. It is preferable that the number of installation of the said anti-rotation protrusion part shall be 1 or more and 4 or less. In consideration of the ease of assembly, one anti-rotation protrusion is installed. However, if the environment is severely vibrated and hit, two or more places should be installed. However, the installation method should be installed at the same angle along the circumference. desirable. That is, it is configured to be installed while maintaining the interval of 180 degrees when installing two places, 120 degrees when installing three places, 90 degrees when installing four places. The number of installation sites may be determined by those skilled in the art in consideration of the shape of the installation site and the surrounding environment such as vibration and hitting. In order to prevent the button from rotating due to hitting or vibration, it is preferable to provide an uneven portion for preventing rotation of the contact portion between the panel and the body. The concave-convex shape is formed to have a shape of a predetermined width and depth in the radial direction with respect to the center of the body, the shape is the same as the concave-convex shape shown on the upper surface of the female screw member 20. When the push button is installed in the panel, a hole 11 into which a body can be inserted into the panel and a semi-circular protrusion assembly hole 12 are formed in cooperation with the hole 11 so that the anti-rotation protrusion 133 may be installed. Processing at the same time. When the body is assembled to the panel 10 as described above, when the anti-rotation protrusion 133 is assembled to the assembly hole 12 of the panel and screwed by the female screw 20, even if excessive load or vibration is applied, the push The button doesn't rotate, so it's always tight.

As can be seen from the above description, in the case of using the pushbutton switch according to the present invention, the terminal contact portion of the reflector does not directly contact the body of the micro switch, so that it is possible to obtain life extension and stability of the lamp holder and the body. In order to compensate for the problem of interference fit, the lower part of the body is provided with a cutout to prevent ease of assembly and damage, and the anti-rotation protrusion is provided on the outer circumferential surface of the upper part of the body to maintain a semi-permanent fastening state even after repeated strong pressing. You can get the effect.
