The diameter of the mounting hole 33 is narrower than the diameter of the constricted portion 22. Therefore, since the seal member 19 is attached to the constricted portion 22 of the operation body 18 by pushing the attachment hole 33, adhesion to the operation body 18 is improved.

  The hook-shaped portion 32 is disposed along the periphery of the guide portion 25 of the holder 17 and is in contact with the annular convex portion 28 formed on the upper surface of the pedestal portion 24 from below. The collar-shaped portion 32 is formed with an annular convex portion 34 that slightly protrudes from the upper surface along the periphery of the bulging portion 31 (see FIG. 4). The hook-shaped portion 32 is sandwiched between the holder 17 and the upper wall portion 11 of the housing 2 in a state where the operation unit 3 is attached to the housing 2. At this time, the adhesiveness between the seal member 19 and the housing 2 is further enhanced by the crushing of the annular convex portion 34 of the bowl-shaped portion 32.

  The operation unit 3 configured as described above is assembled into the housing 2 with only the upper portion of the operation body 18 exposed from the seal member 19. When the upper portion of the operation body 18 is pushed, the upper portion of the seal member 19 is bent and the contact mechanism in the housing 2 is operated.

  The switch unit 4 is configured by attaching first and second terminal portions 42 and 43 to a cover 41 and assembling a contact mechanism to the first and second terminal portions 42 and 43. The cover 41 is formed of an insulating resin and has a lid portion 51 that closes the side opening 15 of the housing 2. On the front surface of the lid portion 51, a terminal holding portion 52 that holds the distal end sides of the first and second terminal portions 42 and 43 is provided. The terminal holding part 52 is formed with two slit holes 53, 53 so that the distal end sides of the first and second terminal parts 42, 43 can protrude out of the housing 2.

  A first support block 54 (presser part) that supports the lower surface of the holder 17 is provided on the upper rear side of the lid part 51. The first support block 54 is in contact with the lower surface of the holder 17 and supports the holder 17 so as to push it up toward the upper wall portion 11 of the housing 2. A second support block 55 that supports the base end sides of the first and second terminal portions 42 and 43 is provided below the back surface of the lid portion 51. The second support block 55 supports the proximal end side of the first terminal portion 42 on the upper surface and supports the proximal end side of the second terminal portion 43 between the lower surface and the bottom wall portion 13 of the housing 2. To do.

  The first terminal portion 42 is formed of a conductive metal plate, has a distal end projecting out of the housing 2 through the cover 41, and a movable contact side of the contact mechanism is incorporated on the proximal end side. The base end side of the first terminal portion 42 has a pair of upright portions 57 that rise from a flat plate portion supported by the second support block 55. A mounting portion 58 that is notched for mounting the spacer member 44 is formed at the front end portion of the pair of standing portions 57. A support portion 59 cut out in a V shape is formed at the rear end of the pair of upright portions 57 so as to support the drive plate 47 in a swingable manner.

  Further, part of the upper end portions of the pair of upright portions 57 are formed at the same height as the upper surface of the first support block 54. Accordingly, part of the upper end portions of the pair of upright portions 57 abuts on the lower surface of the holder 17 and supports the holder 17 so as to push it up toward the upper wall portion 11 of the housing 2. The second terminal portion 43 is formed of a conductive metal plate, has a distal end projecting out of the housing 2 through the cover 41, and forms a fixed contact side of the contact mechanism on the proximal end side. A fixed contact portion 61 is attached to the proximal end side of the second terminal portion 43.

  The spacer member 44 is formed in a plate shape with an insulating resin, and a concave portion 63 corresponding to the fixture 45 is provided on the front surface. The fixture 45 has a piece 64 formed by cutting a part of the metal plate down to the back side. The attachment tool 45 is attached to the recess 63 of the spacer member 44 by inserting the cut piece 64 through the slit hole 65 formed in the spacer member 44. A holding hole 66 that holds one end of the tension spring 46 is formed in the cut-off piece 64. Since the attachment tool 45 is attached to the attachment part 58 of the pair of upright parts 57 via the insulating spacer member 44, it is electrically disconnected from the first terminal part 42.

  The drive plate 47 is formed of a conductive metal plate, is brought into contact with the lower end of the operation body 18 and is operated so as to be swingable with the rear end portion as a fulcrum. The rear end portion of the drive plate 47 is a shaft piece 71 extending in the plate width direction, and is supported by a V-shaped support portion 59 of the pair of standing portions 57. Further, a pair of operation pieces 72 extending downward from both ends in the plate width direction are provided on the front end side of the drive plate 47. Part of the distal end side of the pair of operation pieces 72 is notched in a V shape, and the distal end of the conductor plate 48 is locked.

  The conductor plate 48 is formed in a substantially U shape by connecting a pair of arm portions 73 with a metal plate having springiness and conductivity. The distal end sides of the pair of arm portions 73 are curved and are locked to the pair of operation pieces 72. A movable contact portion 74 is provided at a connecting portion of the pair of arm portions 73, and a holding hole 75 for holding the other end of the tension spring 46 is formed. In this case, the tension of the tension spring 46 acts on the conductor plate 48 so that the movable contact portion 74 is brought into contact with the fixed contact portion 61. Further, the tension of the tension spring 46 acts on the drive plate 47 via the conductor plate 48 so as to push up the operating body 18.

  The switch unit 4 configured as described above is incorporated into the housing 2 to which the operation unit 3 is attached from the side opening 15. Side opening 15 is closed by lid 51 of cover 41, and an adhesive is applied so as to surround lid 51 along the opening edge. With this configuration, the waterproof property from the side of the switch device 1 is enhanced. Further, since the adhesive is applied only around the lid portion 51 of the cover 41, the application amount of the adhesive can be reduced and the working efficiency can be improved. As the adhesive, a thermosetting resin is used. However, the adhesive is not limited to this, and any adhesive may be used as long as the periphery of the lid 51 is sealed in a liquid-tight manner.

  In addition, when the switch unit 4 is attached to the housing 2, the holder 17 is pushed up toward the upper wall portion 11 of the housing 2 by the first support block 54 and the pair of upright portions 57. And the collar-shaped part 32 of the sealing member 19 is crushed between the holder 17 and the peripheral part 16 of the insertion hole 14, and the adhesiveness of the sealing member 19 and the housing 2 is improved. With this configuration, the waterproof property from the upper surface side of the switch device 1 is enhanced.

  With reference to FIG. 4, the attachment structure of the sealing member with respect to a housing is demonstrated. FIG. 4 is a schematic diagram of a seal member mounting configuration according to the first embodiment of the present invention. 4A is a view showing a non-attached state of the seal member, and FIG. 4B is a view showing an attached state of the seal member.

  As described above, the seal member 19 is attached to the housing 2 with the flange portion 32 interposed between the holder 17 and the upper wall portion 11 of the housing 2. Further, the flange portion 32 of the seal member 19 is sandwiched between the holder 17 and the upper wall portion 11 of the housing 2 by the holder 17 being pushed up by the first support block 54 and the pair of upright portions 57. An annular convex portion 34 is formed on the upper surface of the collar portion 32 of the seal member 19. In addition, an annular convex portion 28 is formed on the upper surface of the holder 17 at a position where the collar portion 32 of the seal member 19 is placed.

  As shown in FIG. 4A, the seal member 19 has a thickness A from the lower surface of the bowl-shaped portion 32 to the tip of the annular convex portion 34. The holder 17 has a thickness B from the lower surface of the pedestal portion 24 to the tip of the annular convex portion 28. A gap C is provided between the upper surface of the first support block 54 and the lower surface of the upper wall portion 11 of the housing 2. Similarly, a gap C is also provided between the upper surfaces of the pair of standing portions 57 and the lower surface of the upper wall portion 11 of the housing 2. In this case, the thickness obtained by combining the thickness A of the flange portion 32 of the seal member 19 and the thickness B of the holder 17 is the distance between the first support block 54 (the pair of upright portions 57) and the upper wall portion 11 of the housing 2. It is slightly larger than the interval C (C <A + B).

  Therefore, as shown in FIG. 4B, when the seal member 19 is attached to the housing 2, the first support block 54 and the pair of upright portions 57 squeeze the hook-shaped portion 32 of the seal member 19. Thus, the holder 17 is pushed up. At this time, the annular convex portion 28 of the holder 17 bites into the lower surface of the seal member 19 and strongly presses the annular convex portion 34 of the seal member 19 against the upper wall portion 11 of the housing 2. Then, the annular convex portion 34 of the seal member 19 is crushed, and the gap formed around the operation body 18 in the insertion hole 14 is sealed by the seal member 19. Thus, the switch device 1 can attach the seal member 19 to the housing 2 in close contact with the switch unit 4 attached from the side opening 15 side of the housing 2.

  The operation of the switch device will be described with reference to FIG. FIG. 5 is an operation explanatory diagram of the switch device according to the first embodiment of the present invention. 5A shows a non-operating state of the switch device, and FIG. 5B shows an operating state of the switch device.

  As shown in FIG. 5A, when the operating body 18 is not operated, the tension of the tension spring 46 acts to lower the movable contact portion 74 side of the conductor plate 48. On the other hand, the curved distal ends of the pair of arm portions 73 of the conductor plate 48 push up the pair of operation pieces 72. The drive plate 47 is positioned upward with the V-shaped support portion 59 located on the rear end side as a fulcrum, and pushes up the operating body 18. In this non-operation state, the movable contact portion 74 is brought into contact with the fixed contact portion 61, and the first and second terminal portions 42 and 43 are brought into conduction through the drive plate 47 and the conductor plate 48.

  At this time, since the tension spring 46 and the fixture 45 held by the conductor plate 48 are electrically separated from the pair of standing portions 57 of the first terminal portion 42 by the insulating spacer member 44, the current is not supplied. There is no flow. That is, when the operating body 18 is not operated, the first terminal portion 42 and the second terminal portion 43 are electrically connected via the drive plate 47, the conductor plate 48, the movable contact portion 74, and the fixed contact portion 61. . Therefore, the tension spring 46 does not function as a resistance and is not damaged by heat generation.

  As shown in FIG. 5B, when the operating body 18 is pressed from this non-operating state, the drive plate 47 is swung downward with the V-shaped support portion 59 as a fulcrum. When the drive plate 47 is swung downward, the curved distal end portions of the pair of arm portions 73 of the conductor plate 48 are pushed down via the pair of operation pieces 72. Then, the movable contact portion 74 side of the conductor plate 48 is flipped upward by the tension of the tension spring 46 with the engaging portion with the pair of operation pieces 72 as a fulcrum. Thereby, the movable contact portion 74 and the fixed contact portion 61 are separated from each other, and the conduction state of the first and second terminal portions 42 and 43 is cut.

  Further, when the pressing operation is released from this operation state, the movable contact portion 74 side of the conductor plate 48 is pushed down by the tension of the tension spring 46, and the movable contact portion 74 and the fixed contact portion 61 are brought into contact with each other. Further, the drive plate 47 is pushed up via the pair of operation pieces 72 by the curved distal ends of the pair of arm portions 73 of the conductor plate 48. The drive plate 47 is swung upward with a V-shaped support portion 59 located on the rear end side as a fulcrum, and pushes up the operating body 18. In this way, the switch device 1 is returned to the initial state shown in FIG.

  As described above, according to the switch device 1 according to the present embodiment, the holder 17 is pushed toward the upper wall portion 11 by the switch unit 4 attached from the side opening 15 side of the housing 2. The hook-shaped portion 32 of the seal member 19 is strongly sandwiched between the peripheral portion 16 of the insertion hole 14 and the insertion hole 14. Therefore, the sealing member 19 and the upper wall portion 11 of the housing 2 are brought into close contact with each other, and the waterproofness to the upper side is improved. Further, the side opening 15 of the housing 2 is closed by the lid 51, and an adhesive is applied so as to surround the lid 51 along the opening edge. Therefore, the opening edge part of the side opening 15, the lid part 51, and the gap are sealed with the adhesive, and the waterproofness to the side is enhanced. As described above, in a configuration in which the projecting direction of the first and second terminal portions 42 and 43 projecting from the cover 41 and the operation direction of the operating body 18 projecting from the housing 2 are different, the waterproof property can be enhanced.

  Next, a second embodiment of the present invention will be described. The switch device according to the second embodiment of the present invention differs from the switch device according to the first embodiment described above only in the configuration of the operation unit. FIG. 6 is a cross-sectional view of a switch device according to the second embodiment of the present invention. FIG. 7 is an exploded perspective view of the operation unit according to the second embodiment of the present invention.

  As shown in FIG. 6, the switch device 81 according to the present embodiment is configured such that an operation unit 83 is operably attached to an upper part of a housing 82 and a switch unit 84 is attached from the side opening 95 side of the housing 82. The switch device 81 has the same configuration as the switch device 1 according to the first embodiment described above, except for the operation unit 83. Therefore, the operation unit 83 will be described in particular with reference to FIG.

  As shown in FIG. 7, the operation unit 83 is configured by inserting an operation body 98 into a holder 97 and attaching a seal member 99 so as to cover the operation body 98 from above. The operation body 98 is formed in a substantially rod shape extending in the operation direction by an insulating resin. On the lower end side of the operating body 98, a retaining portion 101 for retaining the holder 97 is provided. Further, the operation body 98 is provided with a pair of convex portions 102 projecting in two directions facing the outer peripheral surface from the retaining portion 101 toward the distal end side. A pair of flat surfaces 103 that are recessed inward in two directions orthogonal to the pair of convex portions 102 are formed on the outer peripheral surface of the operation body 98.

  The holder 97 is formed of the same material as that of the operation body 98 and has a guide portion 106 that protrudes in an annular shape from the upper surface of the pedestal portion 105. A guide hole 107 through which the operating body 98 is inserted is formed in the guide portion 106, and a pair of concave portions 108 are formed on the inner peripheral surface of the guide hole 107 corresponding to the pair of convex portions 102 of the operating body 98. Is formed. The holder 97 guides the operation body 98 in the operation direction by aligning the convex portion 102 of the operation body 98 with the recess 108. In addition, an annular convex portion 109 that slightly protrudes from the upper surface is formed around the guide hole 107.

  The holder 97 and the operation body 98 are formed by separating a single molded body formed of the same material. This formed body is configured by connecting the holder 97 and the operating body 98 in two directions orthogonal to the pair of recesses 108 on the inner peripheral surface of the guide hole 107. Then, the operating body 98 is twisted with respect to the holder 97, whereby the holder 97 and the operating body 98 are separated. In this case, even if the remaining portion of the coupling portion remains on the inner peripheral surface of the guide hole 107, it corresponds to the pair of flat surfaces 103 of the operation body 98, so that the operation body 98 is not hindered from moving in the operation direction. . With such a configuration, variation in dimensions during molding similarly occurs between the operation body 98 and the holder 97, and thus the operation body 98 is guided by the holder 97 satisfactorily.

  The sealing member 99 is formed of a soft elastic material such as rubber, and includes a bulging portion 111 that bulges in a dome shape, and a flange-shaped portion 112 that is formed on the outer peripheral edge portion (lower end peripheral edge portion) of the bulging portion 111. Have. Unlike the seal member 19 according to the first embodiment, the seal member 99 covers the entire operation body 98, so that the waterproof property can be further improved. The hook-shaped portion 112 is disposed along the periphery of the guide portion 106 of the holder 97 and is in contact with the annular convex portion 109 formed on the upper surface of the pedestal portion 105 from below.

  An annular convex portion 113 that slightly protrudes from the upper surface is formed on the flange portion 112 along the periphery of the bulging portion 111. The hook-shaped portion 112 is sandwiched between the holder 97 and the upper wall portion 91 of the housing 82 in a state where the operation unit 83 is attached to the housing 82. At this time, the holder 97 is pushed up toward the upper wall portion 91 of the housing 82 by the switch unit 84 attached to the side opening 95 of the housing 82. And the collar-shaped part 112 of the sealing member 99 is crushed between the holder 97 and the peripheral part 96 of the insertion hole 94, and the adhesiveness of the sealing member 99 and the housing 82 is improved.

  As described above, according to the switch device 81 according to the present embodiment, since the holder 97 and the operating body 98 are formed by separating a single molded body, the variation in dimensions during molding is reduced. 98 and the holder 97 are generated in the same manner, so that the operating body 98 can be well guided by the holder 97. Further, since the seal member 99 covers the entire operation body 98, the waterproof property can be further improved.

  In each of the above-described embodiments, the configuration in which the switch device of the present invention is applied to a stop lamp switch for a motorcycle has been described. However, the present invention is not limited to this configuration. The switch device of the present invention may be applied to any device as long as it is used as a pressing operation type switch device.

  Further, in each of the above-described embodiments, the switch device has a configuration in which the protruding direction of the terminal portion and the operation direction of the operating body are orthogonal to each other while improving the waterproofness, but is not limited to this configuration. . The switch device can have a configuration in which the protruding direction of the terminal portion and the operation direction of the operating body intersect with each other while enhancing waterproofness.

  Further, in each of the above-described embodiments, the first support block and the pair of upright portions increase the adhesion between the seal member and the housing. However, the present invention is not limited to this configuration. Any configuration may be used as long as the adhesion between the seal member and the housing is enhanced by a switch unit attached to the side opening of the housing. For example, the holder may be pushed into the upper wall portion by either the first support block or the pair of upright portions, whereby the adhesion between the seal member and the housing may be increased.
