FIG. 1C is a schematic cross-sectional perspective view of an electronic component control mechanism 100 according to an embodiment of the present invention.

  See FIG. 1C. The control mechanism 100 includes a control member 102, a position restricting member 112, a pressure restricting member 106, and a package component 110. The control member 102 is provided above the position regulating member 112 and is assembled in the package component 110. The package component 110 defines a housing space C, and the pressure regulating member 106 is provided with the position regulating member 112 fixed to the housing space C. The control member 102 has a cap main body 101a and a protrusion 101b extending downward from the bottom surface of the cap main body 101a. The user can operate the control member 102 by pressing the upper part of the cap body 101a. The position restricting member 112 includes a support portion 111 provided between the control member 102 and the electronic elastic piece 116. The support part 111 has a recess for accommodating the protruding part 101 b and has elasticity so as to support the control member 102. When the control member 102 receives pressure, a repulsive force at the time of return is given to the control member 102 by the support part 111, and a user's operational feeling can be improved.

  In the present embodiment, the position regulating member 112 may be made of rubber, and in addition to providing a waterproof function, the electronic elastic piece 116 can be operated in conjunction with the movement of the control member 102. Of course, the material of the position regulating member 112 is not limited to this, and may be other different materials. The electronic elastic piece 116 may be a metal elastic piece, and the material thereof is not limited to this, and may be another different material. See FIG. 1A. When the control member 102 receives pressure, the protruding portion 101b pushes the operating member 114 below the support portion 111, and displaces the operating member 114 according to the movement of the protruding portion 101b. Therefore, the electronic elastic piece 116 can be brought into contact with the electrode 117 on the circuit board 118 in accordance with the operation of the operation member 114 to generate an electronic signal. Therefore, the control mechanism 100 of the present embodiment can be provided on an electronic device (not shown) and can generate an electronic signal in accordance with the operation of the operation member 114.

  The package component 110 has an opening 105, and the control member 102 is provided through the opening 105. The visor 103 of the control member 102 is positioned below the opening 105 and abuts against the upper edge side wall 107 of the recess inside the opening 105.

  The support portion 111 of the position regulating member 112 of the present embodiment has an extending portion 113 that extends in the radial direction. The extending portion 113 is fixed to the pressure regulating member 106 by the recess 115 of the package component 110 so that electronic components such as the electronic elastic piece 116 and the circuit board 118 below the extension portion 113 are normally used without being short-circuited in water. Has been.

  In FIG. 1C, an annular protrusion 113 a is provided corresponding to the extending portion 113. When the package component 110 and the pressure restricting member 106 press-contact the extending portion 113, the annular protrusion 113 a is pushed out and deformed and can be tightly pressed into the annular recess 115. Please refer to FIG. 1A together. Since the opening inner diameter P1 of the pressure restricting member 106 is larger than the outer diameter P2 of the support portion 111, the pressure restricting member 106 contacts the first portion 113b of the extending portion 113, while the second portion 113c of the extending portion 113 is contacted. Does not touch. When the protruding portion 101 b applies pressure to the support portion 111, the support portion 111 and the second portion 113 c of the extending portion 113 move to bring the operating member 114 into contact with the electronic elastic piece 116.

  As is clear from the above description, the extending portion 113 of the position restricting member 112 of this embodiment can be a waterproof rubber washer, and the support portion 111 located in the center can be a member that supports the control member 102. Furthermore, the overall size of the control mechanism 100 can be reduced by reducing the thickness of the position restricting member 112 in accordance with the need for downsizing.

  It should be noted that the pressure regulating member 106 of the present embodiment is provided so as to surround the support portion 111, and the opening inner diameter of the pressure regulating member 106 is larger than the outer diameter of the support portion 111. In order to reduce the pressure receiving area and further improve the durability of the control mechanism 100 against a large water pressure, the position restricting member 112 is positioned between the pressure restricting member 106 and the control member 102, and the pressure restricting member 106 is extended. It abuts on the first portion 113b of the portion 113. In this embodiment, the pressure regulating member 106 is a metal O-shaped ring. Of course, the pressure regulating member 106 may be made of a material whose hardness is harder than that of the position regulating member 112.

  Reference is now made to FIGS. 2A and 2B are a schematic cross-sectional view of a control mechanism 200 for an electronic component according to another embodiment of the present invention, and a schematic exploded view of the component, respectively. FIG. 2C is a schematic cross-sectional perspective view of an electronic component control mechanism 200 according to another embodiment of the present invention.

  See FIG. 2C. The control mechanism 200 includes a control member 202, a position restricting member 212, an actuating member 214, a pressure restricting member 206b, and a package component 210. The control member 202 is provided above the position restricting member 212 and is assembled in the package component 210. The control member 202 has a cap body 201a, and has a protrusion 201b that extends downward from the bottom surface of the cap body 201a. The user can operate the control member 202 by pressing the upper part of the cap body 201a. The position restricting member 212 has a support portion 211 provided between the control member 202 and the operation member 214, and the support portion 211 has elasticity and supports the control member 202. When the control member 202 receives pressure, a repulsive force at the time of return is given to the control member 202 by the support part 211, and the user's operational feeling can be improved.

  In this embodiment, the position restriction member 212 may be made of rubber, and in addition to providing a waterproof function, the electronic switch component 216 is operated in conjunction with the movement of the control member 202 and the operation member 214 below the control member 202. Can be made. Of course, the material of the position regulating member 212 is not limited to this, and may be other different materials. See FIG. 2A. The protruding portion 201 b of the control member 202 is in contact with the support portion 211 and restricts the position of the control member 202 by the position restricting structure 222. When the control member 202 receives pressure, the projecting portion 201b penetrates the position regulating structure 222 and abuts on and pushes the support portion 211, and is positioned above the electronic switch component 216 via the support portion 211. In contact with the actuating member 214, the actuating member 214 is displaced in accordance with the movement of the protrusion 201b. Therefore, the electronic switch component 216 can generate an electronic signal in conjunction with the operation of the operation member 214. Therefore, the control mechanism 200 of the present embodiment can be provided on an electronic device (not shown) and can generate an electronic signal in accordance with the movement of the operating member 214.

  In one embodiment, the actuating member 214 may be made of hard plastic, and the position restricting member 212 may be made of soft rubber or hard rubber. When the compression ratio of the soft rubber is high, the waterproof effect can be enhanced. However, when the support portion 211 is made of soft rubber, the protrusion portion 201b is easily broken and easily damaged. Therefore, in this embodiment, for example, when the support portion 211 is made of a hard rubber having a pressure resistance and the operation member 214 is made of a hard plastic, the fatigue of the material can be prevented and the pressure of the control member 202 can be resisted. Durability can be increased. Of course, the materials of the actuating member 214 and the position regulating member 212 are not limited to these, and other materials having different hardnesses may be used.

  Further, the actuating member 214 corresponds to a protrusion 201 b provided on the control member 202. If the support part 211 is made of a hard rubber having a pressure resistance, and the hard protrusion 201b is brought into direct contact with the hard support part 211 and the hard actuating member 214, the tactile sensation is more directly felt when pressed, Improve the feeling of operation.

  The support part 211 of the position regulating member 212 of this embodiment has an extending part 213 that extends outward. The extending portion 213 is disposed between the control member 202 and the actuating member 214 by the package component 210 so that the electronic components such as the electronic switch component 216 and the circuit board 218 below the extension portion 213 are normally used without being short-circuited in water. It may be fixed to. See FIG. 2C. The package component 210 includes an upper member 204, a lower member 208, a fixing member 206a, and a pressure regulating member 206b. The upper member 204 has an upper opening 205, and a cap main body 201 a is provided in the upper opening 205. The visor 203 of the control member 202 is positioned below the upper opening 205 and abuts against the upper edge side wall 207 of the recess inside the opening 205.

  Further, the lower member 208 has a lower opening 209, and an operating member 214 and a spring 220 are provided in the lower opening 209. In this embodiment, the control member 202, the actuating member 214, and the position restricting member 212 are provided in the accommodation space C formed by assembling the upper member 204, the fixing member 206a, and the lower member 208 to each other. It has been. The pressure regulating member 206b is used to fix and provide the position regulating member 212 in the accommodation space C. As shown in FIG. 2A, the user can push the control member 202 to move the control member 202, the support portion 211, and the operation member 214 within the accommodation space C.

  The upper member 204 and the lower member 208 are made of hard plastic, for example. The fixing member 206 a is provided between the upper member 204 and the lower member 208 and extends to the accommodation space C. The fixing member 206a has a convex portion, and the convex portion of the fixing member 206a and the concave portion of the position restricting structure 222 are engaged with each other, and the distance for pressing the control member 202 can be restricted. A pressure regulating member 206 b is installed on the lower member 208 and is provided so as to surround the support portion 211. Similar to the above-described embodiment, the opening inner diameter of the pressure regulating member 206b is larger than the outer diameter of the support portion 211. The position restricting member 212 is positioned between the pressure restricting member 206b and the control member 202 so that the fixing member 206a, the pressure restricting member 206b, and the lower member 208 form a sealed opening 209a. 206b contacts a first portion (not shown) of the extending portion 213. The extending portion 213 may be assembled to the sealed opening 209a so as to be in a sealed state, and may be pressed between the fixing member 206a, the pressure regulating member 206b, and the lower member 208. For example, as shown in FIG. 2C, the extending portion 213 is provided with an annular protrusion 213a. When the extending portion 213 is assembled to the sealed opening 209a, the annular protrusion 213a is pushed out and deformed to be tightly pressed onto the lower member 208.

  Accordingly, the extending portion 213 of the position restricting member 212 can be fixed by being surrounded by the package component 210 and the pressure restricting member 206b. See FIG. 2D. Under an intense water pressure environment, the pressure receiving area around the support portion 211 can be reduced by using the pressure regulating member 206b of this embodiment. For example, the pressure receiving area A2 is changed from the initial pressure receiving area A1 to obtain a smaller positive pressure below the water surface, and the durability of the control mechanism 200 against a large water pressure is further improved.

  Further, under a strong water pressure environment, the use of the spring 220 of the present embodiment gives a stronger repulsive force to the operating member 214 when returning, thereby improving the user's operational feeling. See FIGS. 2A and 2B. The bottom of the lower member 208 has a position restricting port 219. In the position restricting port 219, a position restricting convex block 215 is provided for the operating member 214. The spring 220 is located in the opening 209 and integrally operates with the operating member 214, and is provided around the operating member 214 in order to provide an elastic force required when the operating member 214 returns. . When the actuating member 214 returns, the position restricting convex block 215 comes into contact with the upper edge side wall 217 protruding above the position restricting convex block 215 to cancel the elastic force of the spring 220.

  As is clear from the above description, the position restricting member 212 and the extending portion 213 of the present embodiment are used as waterproof rubber washers, and the pressure restricting member 206b causes the support portion 211 located in the center to reduce the pressure receiving area and the spring 220. Thus, the operating member 214 positioned below the position restricting member 212 can increase the repulsive force when returning. Thereby, the durability performance of the control mechanism 200 against a large water pressure can be improved, and the user's operational feeling can be improved. Furthermore, the overall size of the control mechanism 200 can be reduced by reducing the thickness of the position restricting member 212 in accordance with the need for downsizing.

  For example, the operation member 214 described above is made of a material different from that of the position regulating member 212 and is assembled in the package component 210. On the other hand, in another embodiment, the actuating member 214 is, for example, a member made of the same material as that of the support portion 211 and is integrally connected to the support portion 211 and then integrally assembled in the package component 210. The present invention is not limited to this.

  3A and 3B are a schematic cross-sectional view of a control mechanism 300 according to still another embodiment of the present invention and a schematic exploded view of components thereof.
