Has been. The movable contact 24 is configured to be separated from the pair of fixed contacts 23 when the bulging portion 17 is elastically restored and pushes up the operation portion 12.

Next, the operation of the reset switch unit 10 in such a portable terminal will be described.
First, the case where this switch part 10 is integrated in the lower case 3 is demonstrated. In this case, the operation unit 12 is stored in a cylindrical storage unit 11 formed integrally with the lower case 3 so as to be slidable in the vertical direction.

  In this state, the cylindrical portion 16 of the cover member 13 is attached to the outer periphery of the cylindrical storage portion 11 from the inner end portion 11a side of the cylindrical storage portion 11 located on the inner side of the lower case 3. At this time, the cylindrical portion 16 is elastically pushed and attached to the outer peripheral surface of the cylindrical storage portion 11. And the press-contact part 19 provided in the upper end surface of the thick part 18 of the cylindrical part 16 is contact | abutted to the inner end part 11a of the cylindrical storage part 11, and the bulging part 17 of the cover member 13 is made into a cylindrical storage part. 11 corresponding to the inner end 11a.

  Thus, the cylindrical portion 16 is in a state where the pressure contact portion 19 of the cylindrical portion 16 is elastically crushed by the inner end portion 11a of the cylindrical storage portion 11, that is, in a state where it is elastically compressed and deformed and pressed. A plurality of rows of pressure contact projections 20 provided in a ring shape are pressed against the outer peripheral surface of the cylindrical storage portion 11 in a state where they are each elastically compressed and deformed.

  In this state, the plurality of rows of press contact protrusions 20 are in pressure contact with the outer peripheral surface of the cylindrical storage portion 11 with the outer peripheral surface of the cylindrical storage portion 11 being tightened. For this reason, the cylindrical part 16 is attached to the outer peripheral surface of the cylindrical storage part 11 so that the cylindrical part 16 does not come out of the outer peripheral surface of the cylindrical storage part 11. Thereby, the inclination of the cylindrical part 16 by the withdrawal of the cylindrical part 16 with respect to the cylindrical storage part 11 is prevented, and the attachment state of the cylindrical part 16 with respect to the cylindrical storage part 11 is stabilized.

  In this case, the plurality of rows of press contact protrusions 20 are formed in a substantially circular cross section that protrudes from the inner peripheral surface and the outer peripheral surface of the cylindrical portion 16. For this reason, the arc-shaped portion 20 a protruding to the inner peripheral surface of the cylindrical portion 16 is strongly pressed against the outer peripheral surface of the cylindrical storage portion 11 by the arc-shaped portion 20 b protruding to the outer peripheral surface of the cylindrical portion 16. .

  As a result, the plurality of rows of press contact projections 20 are in a state where the arc-shaped portion 20a protruding on the inner peripheral surface of the cylindrical portion 16 is elastically crushed, that is, in a state where it is elastically compressed and deformed. It is strongly tightened and pressed against the outer peripheral surface of the cylindrical storage portion 11. For this reason, the cylindrical part 16 is securely and firmly attached to the outer peripheral surface of the cylindrical storage part 11. Thereby, since the inner end part 11a of the cylindrical storage part 11 is sealed by the cover member 13, waterproofness is ensured.

  In this state, the bulging portion 17 of the cover member 13 is elastically swollen into a dome shape, so that the operation portion 12 housed in the cylindrical housing portion 11 is pushed up by the elastic force of the bulging portion 17. The upper end surface of the operation unit 12 is elastically pressed against the periphery of the through hole 15 of the lower case 3. Thus, in a state where the upper end surface of the operation unit 12 closes the through hole 15 of the lower case 3, a part of the upper end surface of the operation unit 12 passes through the through hole 15 from the lower case 3 (on the upper surface side in FIG. 3). ) Exposed.

  In this state, the bulging portion 17 of the cover member 13 is elastically bulging into a dome shape, so that the key contact portion 14 provided on the lower surface of the pressing portion 17a located in the bulging portion 17 is movable. The contact 24 is separated from the pair of fixed contacts 23 on the substrate 22 provided on the lower surface of the cover member 13. As a result, the key contact portion 14 is turned off.

Next, the operation of the reset switch unit 10 will be described.
In this case, a thin rod-like member (not shown) is inserted into the through hole 15 of the lower case 3 from the outside, and the operation portion 12 is pushed against the elastic force of the bulging portion 17 of the cover member 13. Then, as shown in FIG. 5, the bulging portion 17 of the cover member 13 is pushed by the operation portion 12 and elastically deformed.

  At this time, since the cylindrical portion 16 is in pressure contact with the outer peripheral surface of the cylindrical storage portion 11 by a plurality of rows of pressing contact projections 20, the bulging portion 17 of the cover member 13 is operated as shown in FIG. The cylindrical portion 16 does not come out of the outer peripheral surface of the cylindrical storage portion 11 even if it is pushed by the elastic deformation, and the inclination of the cylindrical portion 16 due to the withdrawal of the cylindrical portion 16 with respect to the cylindrical storage portion 11 is suppressed. Then, the mounting state of the cylindrical portion 16 with respect to the cylindrical storage portion 11 is stabilized, and this stable state is maintained.

  Further, when the bulging portion 17 of the cover member 13 is pushed and elastically deformed by the operation portion 12, as shown in FIG. 5, the movable portion provided on the lower surface of the pressing portion 17 a located in the bulging portion 17. The contact 24 comes into contact with a pair of fixed contacts 23 on the substrate 22 disposed under the cover member 13 to make the pair of fixed contacts 23 conductive. As a result, the key contact portion 14 is turned on.

  When the pressing operation of the bulging portion 17 of the cover member 13 by the operating portion 12 is released, the bulging portion 17 of the pressed cover member 13 is elastically returned to the initial state as shown in FIG. . Then, the operation unit 12 is pushed up, and the movable contact 24 is separated from the pair of fixed contacts 23. As a result, the key contact portion 14 is turned off, and the operation portion 12 returns to the initial state.

  As described above, according to the reset switch unit 10 in the portable terminal, the lower case 3 in which the cylindrical storage unit 11 that slidably stores the operation unit 12 is provided, and the lower case 3 is provided. The cylindrical portion 16 mounted on the outer periphery of the cylindrical storage portion 11 and when pressed by the operation portion 12 in a state where the cylindrical storage portion 11 is closed, the key contact portion 14 is switched by being elastically deformed. A cover member 13 having a bulging portion 17, and the cylindrical portion 16 of the cover member 13 is provided with a plurality of rows of press-contact projections 20 that are in annular contact with the outer peripheral surface of the cylindrical storage portion 11. Thus, waterproofness can be secured with a simple structure.

  That is, in the reset switch unit 10, the cylindrical part 16 of the cover member 13 is disposed on the outer periphery of the cylindrical storage part 11 in a state where the operation part 12 is stored in the cylindrical storage part 11 provided in the lower case 3. Since the structure is simple, the cover member 13 can be easily and easily attached to the cylindrical storage portion 11, and a plurality of rows provided annularly on the cylindrical portion 16 of the cover member 13. Since the pressure contact projection portion 20 allows the cover member 13 to be securely pressed against the outer peripheral surface of the cylindrical storage portion 11, waterproofness can be ensured.

  In this case, the cylindrical portion 16 is pressed against the outer peripheral surface of the cylindrical storage portion 11 by the plurality of rows of press contact protrusions 20, thereby preventing the cylindrical portion 16 from coming out of the outer peripheral surface of the cylindrical storage portion 11. Therefore, it is possible to prevent the tubular portion 16 from being inclined due to the tubular portion 16 being pulled out of the tubular storage portion 11, so that the mounting state of the tubular portion 16 with respect to the tubular storage portion 11 is always kept constant. It can be stabilized. For this reason, when the switch unit 10 is assembled, it is possible to prevent the cover member 13 from being attached to the cylindrical storage unit 11 and to ensure stable waterproof performance.

  As a result, in the reset switch portion 10, the bulging portion 17 of the cover member 13 is pushed up by the operation portion 12 while the operation portion 12 is elastically pushed up while the cylindrical housing portion 11 is closed. Since the structure is elastically deformed, the operation section 12 can be smoothly and satisfactorily slid in the cylindrical storage section 11 in accordance with the elastic deformation of the bulging section 17.

  In this case, the cover member 13 includes the cylindrical portion 16, the bulging portion 17, and the plurality of press contact projection portions 20 that are integrally formed of an elastic material such as silicone resin, urethane resin, or elastomer. 13 can be easily and easily manufactured, and the cylindrical portion 16 of the cover member 13 can be elastically pushed and easily mounted on the outer periphery of the cylindrical storage portion 11. It can be easily and easily attached to the cylindrical storage portion 11.

  Further, each of the plurality of rows of press contact protrusions 20 is formed in a substantially circular cross section that protrudes from the inner peripheral surface and the outer peripheral surface of the cylindrical portion 16 of the cover member 13, so that the cylindrical portion of the cover member 13 is formed. When mounting 16 on the outer periphery of the cylindrical storage portion 11, the arc-shaped portion 20 a protruding on the inner peripheral surface of the cylindrical portion 16 is formed into a cylinder by the arc-shaped portion 20 b protruding on the outer peripheral surface of the cylindrical portion 16. It can be strongly pressed against the outer peripheral surface of the shape storage portion 11.

  For this reason, the plurality of rows of pressing projections 20 are cylindrical in a state in which the arc-shaped portion 20a protruding on the inner peripheral surface of the cylindrical portion 16 is elastically crushed, that is, in a state of being elastically compressed and deformed. Since the outer peripheral surface of the storage portion 11 can be strongly tightened, a plurality of rows of press contact protrusions 20 can be pressed against the outer peripheral surface of the cylindrical storage portion 11. Thereby, since the cylindrical part 16 can be reliably and firmly attached to the outer peripheral surface of the cylindrical storage part 11, the inner end portion 11a of the cylindrical storage part 11 can be reliably sealed by the cover member 13. This makes it possible to further improve waterproofness.

  Further, the cover member 13 is provided with a pressure contact portion 19 that is in pressure contact with the inner end portion 11 a of the cylindrical storage portion 11, so that the cylindrical portion 16 of the cover member 13 is attached to the outer peripheral surface of the cylindrical storage portion 11. In this case, the pressure contact portion 19 of the cylindrical portion 16 can be pressed against the inner end portion 11 a of the cylindrical storage portion 11, whereby the pressure contact portion 19 of the cylindrical portion 16 is pressed against the inner end portion of the cylindrical storage portion 11. 11a can be pressed in a state of being elastically crushed, that is, in a state of being elastically compressed and deformed, so that the waterproofness can be further enhanced.

  In this case, since the thick portion 18 is formed in the lower portion of the cylindrical portion 16 located on the inner side of the lower case 3 so as to protrude into the cylindrical portion 16, the cylindrical portion 16 is accommodated in the cylindrical shape. When mounted on the outer peripheral surface of the portion 11, the upper end surface of the thick portion 18 can be brought into elastic contact with the inner end portion 11 a of the cylindrical storage portion 11, and the press contact portion is contacted with the upper end surface of the thick portion 18. 19 is provided, when the upper end surface of the thick wall portion 18 is elastically contacted with the inner end portion 11a of the cylindrical storage portion 11, the press contact portion 19 is reliably pressed against the inner end portion 11a of the cylindrical storage portion 11. Can be made.

  Further, in the reset switch unit 10, the key contact portion 14 corresponds to the bulging portion 17 provided on the substrate 22 disposed below the cover member 13 corresponding to the bulging portion 17 and the bulging portion 17. A pair of fixed contacts 23 and a movable contact 24 provided on the bulging portion 17 so as to come into contact with and detachable from the pair of fixed contacts 23. When the protruding portion 17 is pushed and elastically deformed, the key contact portion 14 can be reliably and satisfactorily switched.

  That is, when the bulging portion 17 of the cover member 13 is pushed and elastically deformed by the operation portion 12, the key contact portion 14 converts the movable contact 24 provided in the bulging portion 17 into a pair of fixed contacts 23. Since they can be brought into contact with each other, the pair of fixed contacts 23 can be brought into conduction by the movable contact 24, whereby the key contact portion 14 can be reliably turned on to output an electrical signal as an on signal.

  In addition, when the pressing force of the operation unit 12 on the bulging part 17 of the cover member 13 is released, the key contact part 14 is elastically returned to the original shape by the bulging part 17 being restored to its original shape. Since the movable contact 24 provided on the movable contact 24 can be reliably separated from the pair of fixed contacts 23, the conduction state of the pair of fixed contacts 23 by the movable contact 24 can be released, and thus the key contact portion 14 can be securely connected. In addition, it can be turned off well.

  In the above-described embodiment, the case where the cover member 13 is formed of an elastic material that does not transmit light has been described. However, the present invention is not limited to this, and the cover member is formed of an elastic material having light transmittance such as transparent or translucent. 13 may be formed. When the cover member 13 is formed of such a light-transmitting elastic material, when the cylindrical portion 16 of the cover member 13 is attached to the outer peripheral surface of the cylindrical storage portion 11, Therefore, the attachment position and attachment state of the cylindrical part 16 with respect to the cylindrical storage part 11 can be confirmed visually.
