Description

  The present invention relates to a waterproof push button switch member and an electronic apparatus including the same.

  Recently, there is an increasing demand for a waterproof function for small electronic devices such as mobile phones and portable terminals (PDAs). There are many flooded locations in such equipment, but the main location is a plurality of openings provided to expose the push button to the outside. The flooding from the opening may cause an electrical short inside the device and reduce the reliability of the device. Therefore, in order to prevent such problems from occurring as much as possible, a waterproof structure in which an elastic member is interposed between the push button and the switch on the circuit board inside the device, and a part of the contact portion between the opening and the elastic body is in close contact with each other. Is known (see, for example, Patent Document 1).

  The waterproof structure disclosed in Patent Document 1 includes a cup member made of an elastic material attached to a through-hole so that the opening side faces the outside of the device, and a push button including a shaft portion inserted into the opening of the cup member. And a cylindrical holder made of resin or metal is mounted inside the cup member. Due to the presence of the cylindrical holder, the shape of the cup member can be maintained and the adhesion between the through hole and the cup member can be maintained, and the push button switch member having such a waterproof structure can be easily incorporated into the device. .

  The push button 20 is a member that is partially exposed from the cover member 30 and can be driven toward the container portion 10a of the waterproof member 10, and is provided with the same number as the number of the container portions 10a. The push button 20 includes a flange portion 21, a key top 22 that protrudes from one plane of the flange portion 21 and has a bottom surface that is smaller in diameter than the flange portion 21, and the other plane that is opposite to the key top 22 of the flange portion 21. And a shaft portion 23 having a bottom surface smaller than the flange portion 21. The flange portion 21, the key top 22, and the shaft portion 23 may constitute the push button 20 by bonding them separately formed, or the push button 20 may be integrally formed. From the viewpoint of simplification of the manufacturing process and cost reduction, it is preferable to form the push button 20 by integral molding as in the latter case. Note that the push button 20 is not limited to a form including one shaft portion 23 and one key top 22, but includes one or more key tops 22 on a resin sheet or elastic sheet including a plurality of shaft portions 23. Form may be sufficient. In this embodiment, the flange portion 21 has a thin disk shape. Further, the key top 22 has a trapezoidal shape in which the horizontal cross section gradually decreases from the flange portion 21, and has a form in which most of the height direction can be inserted from a through hole (described later) of the cover member 30. The shaft portion 23 has a diameter that can be inserted from the opening portion 12 of the container portion 10a of the waterproof member 10, and can contact the bottom portion of the container portion 10a to turn on the switch by pressing the push button 20. It has a length sufficient to secure the driving amount. The shaft portion 23 has a trapezoidal shape that gradually decreases the horizontal cross section from the flange portion 21 in the opposite direction. The push button 20 is disposed on the waterproof push button switch member 3 with the key top 22 penetrating from the inside to the outside of the cover member 30 and the shaft portion 23 being inserted into the container portion 10a.

  The shape of the flange portion 21 may be a shape other than a circular plate, for example, a rectangular or triangular plate. Further, the key top 22 and the shaft portion 23 may have a shape other than a trapezoid, for example, a cylindrical shape or a rectangular parallelepiped shape. The push button 20 is preferably made of a material harder than the waterproof member 10, for example, resin, metal, ceramics, graphite, or the like. Examples of the metal include stainless steel, aluminum, aluminum alloy, and iron. Examples of the resin include acrylic, polypropylene (PP), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyamide (PA), polycarbonate (PC), or a polymer alloy composed of two or more resins. Examples of ceramics include alumina, silicon nitride, and zirconia.

  As shown in FIG. 3, each container part 10a is provided with the annular rib 13 formed continuously along the surrounding surface of the outer surface. The annular rib 13 is an example of a waterproof mechanism that provides waterproofing with respect to the housing disposed inside the electronic device 1. The annular rib 13 is preferably formed in parallel with the opening 12 of the container portion 10a. However, the annular rib 13 can also be formed non-parallel to the opening 12. The annular rib 13 may be configured separately from the container portion 10a and may be bonded to the container portion 10a, or the container portion 10a in which the annular rib 13 is integrated may be manufactured. From the viewpoint of high waterproofness, simplification of the manufacturing process, and cost reduction, it is preferable to form the container portion 10a by integrally forming the annular rib 13 as in the latter case. The annular rib 13 will be described in detail later.

  The cover member 30 is preferably configured from a material harder than the waterproof member 10 on the outer side of the waterproof member 10, for example, one or a combination of two or more of the constituent materials of the push button 20 illustrated above. . Moreover, the cover member 30 can also be comprised from the same material (elastic material) as the waterproof member 10. The cover member 30 has the same elongated shape as the waterproof member 10. The cover member 30 has a through hole 31 of a size that can be inserted through the key top 22 of each push button 20 but not through the flange 21 in series in the length direction of the cover member 30 at a position facing each container portion 10a. Prepare for. The cover member 30 is provided with a form that can be fitted and fixed to the waterproof member 10 preferably. However, the cover member 30 may be fixed to the waterproof member 10 by adhesion, screwing, or the like. Furthermore, the cover member 30 can be fixed to the inner housing of the electronic apparatus 1 and may simply sandwich the waterproof member 10.

  FIG. 4 shows a main cross-sectional view of the waterproof pushbutton switch member according to the first embodiment set in an electronic device and an enlarged view of a part X thereof.

  The waterproof member 10 is disposed in a state where the container portion 10 a is inserted into the insertion port 41 formed in the housing 40 inside the electronic device 1 and the elastic flange portion 10 b is placed on the outer surface of the housing 40. The container part 10a is arrange | positioned in the state which inserted the reinforcement member 50 inside. The reinforcing member 50 is a bottomed cup-shaped member having an opening in the direction of the opening 12 of the container 10a. The reinforcing member 50 is fixed to the inside of the container 10a in a state where the bottom is in contact with the bottom of the container 10a. The As shown in the enlarged view of a part X in FIG. 4, the container portion 10 a is disposed in the insertion port 41 with the annular rib 13 being in pressure contact with the inner wall of the insertion port 41 of the housing 40. Both the annular rib 13 and the inner wall of the insertion port 41 of the housing 40 constitute a waterproof mechanism. Since the reinforcing member 50 is a bottomed cup-shaped member, it has a function of maintaining the radial shape of the container portion 10a. Therefore, the adhesiveness between the annular rib 13 and the insertion port 41 can always be maintained. In addition to the functions other than those described above, the reinforcing member 50 has a function that facilitates insertion of the container portion 10a into the insertion port 41 of the housing 40 and a pressing of the push button 20 so that the shaft portion 23 does not break the bottom of the container portion 10a. It also has the function to do. Further, as will be described later, when the shaft portion 23 pushes the bottom portion of the reinforcing member 50 and a switch disposed below the shaft portion 23 is pushed by the container portion 10a, the reinforcing member 50 gives a good pressing feeling to the user. It also has the function.

  The reinforcing member 50 for exhibiting such a function is preferably composed of a material harder than the waterproof member 10, for example, resin, metal, ceramics, graphite or the like. Examples of the metal include stainless steel, aluminum, aluminum alloy, and iron. Examples of the resin include acrylic, polypropylene (PP), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyamide (PA), polycarbonate (PC), or a polymer alloy composed of two or more resins. Examples of ceramics include alumina, silicon nitride, and zirconia. When lightening, thinning and shortening, the reinforcing member 50 is preferably made of a highly rigid metal member. When the key top 22 is illuminated from the inside, the reinforcing member is made of a highly permeable resin. 50 is preferred.

  The push button 20 is disposed by inserting the shaft portion 23 into the container portion 10 a and contacting the bottom portion of the reinforcing member 50. The cover member 30 is inserted into the key top 22 of the push button 20 through the through hole 31, and the waterproof member 10 is in a state where the flange portion 21 of the push button 20 is in contact with the back surface of the flange 32 formed around the through hole 31. It is fixed to the cover housing 40 from the outside. The cover member 30 is provided with an annular convex portion 33 projecting inwardly on the back surface on the outer peripheral side of the through-hole 31 so that the elastic flange portion 10b is pressed toward the housing 40 by the annular convex portion 33. The electronic device 1 is set. When the annular convex portion 33 is strongly pressed against the elastic flange portion 10b, the annular convex portion 33 can function as a waterproof member. However, since waterproofing is achieved by pressure contact between the annular rib 13 formed in the container portion 10a and the inner wall of the insertion port 41 of the housing 40, waterproofing by the annular convex portion 33 is not essential. Therefore, the annular protrusion 33 may not be formed on the cover member 30.

  A circuit board 60 is disposed inside the housing 40. The circuit board 60 includes a switch board 61 on the front side surface. The switch board 61 includes a dome switch 62 as an example of a switch at a position below the insertion port 41 of the housing 40. The dome switch 62 is made of a material having excellent conductivity, for example, steel. The annular lower end of the dome switch 62 is electrically connected to an electrode 63 formed on the switch substrate 61. In addition, an electrode 64 that is not in electrical contact with the electrode 63 is disposed on the switch substrate 61 and immediately below the convex portion of the dome switch 62. Since the dome switch 62 is fixed to the switch substrate 61, the switch substrate 61 and the region excluding the region in contact with the container portion 10a above and the switch substrate 61 are covered with the sheet 65. The sheet 65 is covered except for the region in contact with the container portion 10a because the member sandwiched between the shaft portion 23 and the dome switch 62 does not intervene with a soft material as much as possible to provide a good pressing feeling. This is to give to the user.

  When the inside of the electronic device 1 and the waterproof pushbutton switch member 3 have the above-described configuration, when the key top 22 is pushed inward of the electronic device 1, the shaft portion 23 passes through the reinforcing member 50 and the container portion 10 a Push the bottom inward. Then, the connection area | region of the elastic flange part 10b of the waterproof member 10 and the container part 10a is extended, the container part 10a moves to the inner side of the electronic device 1, and the dome switch 62 is dented. As a result, the electrode 63 and the electrode 64 are electrically connected via the dome switch 62, and the switch is turned on. The distance from the flange 32 of the cover member 30 to the elastic flange portion 10b is such that the flange portion 21 does not come into contact with the elastic flange portion 10b until the shaft portion 23 has depressed the dome switch 62 and turned on. , Longer than the movable distance of the shaft portion 23. When the container portion 10 a moves inward, the annular rib 13 moves through the insertion port 41 toward the inside of the electronic device 1 while maintaining a pressure contact state with the inner wall of the insertion port 41. For this reason, high waterproofness can be exhibited even when the push button 20 is pressed.

  When the key top 22 is pushed inward toward the inner side of the electronic device 1 and then the pressure is released, the dome switch 62 tries to return to its original state due to its elasticity. At the same time, the elastic flange portion 10b around the opening 12 of the container portion 10a also tries to return to its original state from the extended state. As a result, the push button 20 and the container part 10a move to the outer side of the electronic device 1. The electrodes 63 and 64 return to the non-contact state electrically when the dome switch 62 returns to its original shape, and the switches are turned off. Note that turning on or off of the above-described switch may be the reverse of the above.

2. Second Embodiment Next, a waterproof pushbutton switch member and an electronic apparatus including the same according to a second embodiment of the present invention will be described. In the second embodiment, parts that are the same as those in the above embodiment are given the same reference numerals, and redundant descriptions are omitted. The waterproof pushbutton switch member according to the second embodiment is different from that according to the first embodiment in the form of the waterproof mechanism, and the other points are the same as those in the first embodiment.

  FIG. 5 shows a main cross-sectional view of the waterproof pushbutton switch member according to the second embodiment set in an electronic device and an enlarged view of a part Y thereof.

  As shown in the enlarged view of part Y in FIG. 5, the container portion 10 a includes an annular fitting protrusion 15 formed continuously along the peripheral surface on the outer surface thereof. The annular fitting protrusion 15 is preferably formed in parallel with the opening 12 of the container 10a. The insertion port 41 of the housing 40 includes an annular fitting groove 42 that is continuously formed along the inner wall thereof. The annular fitting groove 42 has a form that fits with the annular fitting protrusion 15. The annular fitting groove 42 and the annular fitting protrusion 15 are an example of a waterproof mechanism portion that is in close contact with each other and is waterproofed inwardly therefrom. The container portion 10 a is disposed in the insertion port 41 of the housing 40 in a state where the annular fitting protrusion 15 is fitted in the annular fitting groove 42. Since the reinforcing member 50 is a bottomed cup-shaped member, it has a function of maintaining the radial shape of the container portion 10a. Therefore, the adhesion between the annular fitting protrusion 15 and the annular fitting groove 42 can always be maintained. The annular fitting projecting portion 15 is preferably a neck having a thickened end portion that is directed radially outward from the outer surface of the container portion 10a, and a position that is directed radially inward from the end portion is thinner than the end portion. The unit 16 is provided. In particular, the annular fitting protrusion 15 is configured so that the end of the annular fitting protrusion 15 is fitted into the annular fitting groove 42 and the neck 16 is positioned in the vicinity of the opening of the annular fitting groove 42. Is preferred. Further, the annular fitting protrusion 15 has a protruding shape that does not have the neck portion 16 like the annular rib 13 in the first embodiment, and the annular fitting groove 42 does not have a constriction in the opening portion. As the push button 20 is pushed in and released, the annular fitting protrusion 15 may be vertically movable in the annular fitting groove 42 without bending from a specific portion.

  6 is a partial cross-sectional view showing a change in the state of the waterproof mechanism before and after pressing the push button in the waterproof push button switch member shown in FIG.

  When the key top 22 is pushed inward of the electronic device 1, the shaft portion 23 pushes the bottom portion of the container portion 10 a inward through the reinforcing member 50. Then, the connection area | region of the elastic flange part 10b of the waterproof member 10 and the container part 10a is extended, the container part 10a moves to the inner side of the electronic device 1, and the dome switch 62 is dented. As a result, the electrode 63 and the electrode 64 are electrically connected via the dome switch 62, and the switch is turned on. At this time, as shown in FIG. 6, the annular fitting protrusion 15 of the container portion 10 a bends from the neck portion 16 with its end portion held in the annular fitting groove 42, and the electronic device of the container portion 10 a. 1. Inward movement (movement in the direction of the black arrow) is allowed. The annular fitting protrusion 15 has a sufficient length and flexibility so as not to be detached from the annular fitting groove 42 when the container portion 10a moves inward. The annular fitting protrusion 15 may be bonded to the outer wall of the container part 10a separately from the container part 10a, but from the viewpoint of high waterproofness, high strength, simplification of the manufacturing process, and cost reduction. It is preferable to manufacture the container unit 10a integrally by integral molding.

  When the key top 22 is pushed inward toward the inner side of the electronic device 1 and then the pressure is released, the dome switch 62 tries to return to its original state due to its elasticity. At the same time, the elastic flange portion 10b around the opening 12 of the container portion 10a also tries to return from the extended state to the original state, and the annular fitting protrusion 15 also tries to return to the original state. As a result, the push button 20 and the container part 10a move to the outer side of the electronic device 1.

3. Other Embodiments As described above, each embodiment of the waterproof pushbutton switch member and the electronic device using the same has been described, but the present invention is not limited to each of the above embodiments. Various modifications can be made.

  FIG. 7 shows a cross-sectional view of a modified example of the insertion opening of the housing shown in FIG. 4 and an enlarged view of a part Z thereof.

  The insertion port 41 of the housing 40 shown in FIG. 4 has an inner surface with no irregularities, but as shown in FIG. 7, from the insertion port 41 to the inside in the radial direction, the annular rib 13 of the container portion 10 a. An annular projecting portion 45 may be provided in the outward direction to prevent the container portion 10a from coming out in the outward direction. In this case, when the waterproof member 10 is set on the housing 40, the annular rib 13 is deformed inward in the radial direction, and the protruding portion 45 of the insertion port 41 is climbed. Unless a very large pulling force is applied to 10a, the container portion 10a cannot be easily removed from the insertion port 41. Note that the protrusion 45 may be formed as a flange in the outer opening of the insertion port 41. Furthermore, the protruding portion 45 is not necessarily formed continuously in an annular shape, and may be configured to partially protrude on the inner periphery of the insertion port 41.

  The reinforcing member 50 is fixed inside the container portion 10a, but may be embedded inside the container portion 10a or fixed outside the container portion 10a. The strong member 50 may be simply arranged without being fixed inside the container portion 10a. In addition, a switch other than the dome switch 62, for example, a tact switch or the like may be disposed inside the electronic device 1 from the housing 40. In that case, the push button 20 returns to the original position exclusively by the elastic deformation of the waterproofing member 10 when the pressing is released after the pressing.

  While maintaining the combination of the annular fitting protrusion 15 and the annular fitting groove 42 as an example of the waterproof mechanism part, the annular fitting groove 42 is provided on the container 10a side, and the inner wall side of the insertion port 41 of the housing 40 is provided. The annular fitting protrusions 15 may be formed respectively, and the concavo-convex relationship in the second embodiment may be reversed.

  The present invention can be used as a push button switch member incorporated in a waterproof device.
