The conventional rotary electronic component has the following problems.
[1] The rotating body 530 is pivotally supported at two places: a shaft portion 537 that is pivotally supported by the shaft support portion 512 of the cover 510 and a shaft protrusion 536 that is pivotally supported by the hole 564 of the case 560. Therefore, when rotating the rotating body 530, torque unevenness may occur. That is, the rotating body 530 is pivotally supported at two places above and below it, and the parts to be pivotally supported are separate parts (cover 510 and case 560). The central axis and the central axis of the hole 564 do not exactly match. For this reason, when rotating the rotary body 530 as mentioned above, there was a possibility of causing torque unevenness.

[2] The rotating body 530 is made of synthetic resin, and the case 560 is also made of synthetic resin. Therefore, when the rotating body 530 is rotated, static electricity is generated between the rotating body 530 and the case 560 (in this example, the circuit board 565 made of synthetic resin installed in the case 560) that is in contact with the rotating body 530. Will occur. Since the position where this static electricity is generated is a position close to a sliding contact pattern (not shown) formed on the slider 550 and the circuit board 565, the static electricity easily enters these, causing noise.

[3] As shown in FIG. 7, a pair of side walls 511, 511 that are bent at a right angle downward and hang down are provided on a pair of opposed outer peripheries of the rectangular upper surface plate 515 of the cover 510, and the lower ends thereof From the portion, tongue-shaped attachment portions 513 and 513 for attaching the rotary electronic component to other members such as a main circuit board are projected. The width dimension between the mounting portions 513 and 513 is determined by design from the relationship with the main circuit board to which the mounting portion 513 and 513 are mounted, whereby the width between the outer surfaces of the case 560 on the side contacting the side wall portions 511 and 511 is determined. Dimensions are also determined. Since the rotary electronic component has a structure in which the ring-shaped click plate 522 is stored in the rotating body storage recess 561 of the case 560, if the width dimension between the mounting portions 513 and 513 is small, the rotating body storage recess 561 Therefore, the outer diameter of the click plate 522 is restricted by the inner diameter of the rotating body housing recess 561 and becomes smaller. On the other hand, the width dimension of the click plate 522 needs to be greater than a predetermined dimension because the strength needs to be maintained at a predetermined value or more, and the inner diameter must be reduced by the amount corresponding to the decrease in the outer diameter. On the other hand, when the external dimensions of the shaft portion 537 of the rotating body 530 passing through the center of the click plate 522 are determined by design, the cover abutting portion 539 of the upper portion of the rotating body main body portion 531 provided with the click portion 535 is eventually formed. The diameter (that is, the dimension substantially the same as the inner diameter dimension of the click plate 522) is decreased, and the radial width dimension L1 of the ring-shaped upper surface of the cover contact portion 539 is decreased. Although the upper surface of the cover contact portion 539 is brought into contact with the lower surface around the shaft support portion 512 of the cover 510, the width of the upper surface of the cover contact portion 539 is prevented. If L1 becomes small, the prevention strength of the rotator 530 will decrease. Similarly, the diameter dimension of the shaft protrusion 536 on the lower surface of the rotating body 530 is small due to the structure penetrating the center of the slider 550. For this reason, the length dimension (width dimension) in the radial direction of the stepped portion 541 provided on the shaft protrusion 536 is also reduced, and the fracture prevention strength (pressure fracture prevention strength) when the rotating body 530 is pressed from above is also low.

  The present invention has been made in view of the above points, and its purpose is to prevent torque unevenness during rotation of the rotating body, to prevent noise from entering the electrical output, and to prevent the rotor from coming off and to prevent pressure breakage. An object of the present invention is to provide a rotary electronic component that can increase strength.

According to the second aspect of the present invention, since the rotating body is pivotally supported only by the shaft support portion provided on the cover, torque unevenness at the time of rotating the rotating body that occurs when the rotating body is pivotally supported at two locations. Can be prevented.
Further, since the synthetic resins do not slidably contact each other in the vicinity of the electrical function portion, static electricity does not enter the electrical function portion, and noise can be prevented.
In addition, since the case mounting portion of the rotating body main body is mounted on the rotating body mounting portion of the case, the strength against pressure breakage of the rotating body can be increased.

Keep it big. As a result, the strength of preventing the rotor from coming off can be strongly maintained. Even if the width between the side plates is reduced, it is not necessary to reduce the width of the click plate, so that the strength of the click plate can be kept strong.
Further, in claim 2 , since the case mounting portion of the rotating body main body is mounted on the rotating body mounting portion of the case, the case mounting portion has a dimension that protrudes outward from the inside of the rotating body housing recess of the case. Can be formed. For this reason, the outer diameter dimension of the rotating body main body can be increased, the width dimension of the upper surface of the cover abutting portion can be increased, and the preventing strength of the rotating body can be further increased.
According to the invention described in claim 3, since the metal click plate is attached in a state of being electrically connected to the metal cover, the case mounting of the rotating body located in the vicinity of the click plate The static electricity generated by the sliding portion between the portion and the rotating body mounting portion of the case is likely to enter the click plate. For this reason, it can prevent more reliably that static electricity penetrate | invades into an electrical function part, and can generate | occur | produce noise more reliably.

  A flexible circuit board 30 is installed on the bottom surface of the rotating body housing recess 13 of the case 10 with its top surface exposed. Two slidable contact patterns 31 are formed concentrically on the upper surface of the flexible circuit board 30, and one end of each terminal plate 45 is placed on a terminal connection pattern (not shown) drawn from there to the vicinity of the outer periphery of the flexible circuit board 30. The terminal plates 45 are attached to the case 10 by forming the case 10 above and below the contact connecting portion. Each terminal plate 45 is bent at a substantially right angle in the downward direction at a portion protruding to the outside of the case 10.

  The rotating body 50 is an integrally molded product of synthetic resin, and is a substantially cylindrical shaft having an outer diameter smaller than the outer diameter of the rotating body main body 51 from the center of the upper surface of the substantially disk-shaped rotating body main body 51. The portion 53 is configured to protrude. A case placement portion 55 is provided on the outer periphery of the rotating body main body 51 so as to project in a ring shape. As a result, a cover contact portion 57 protruding in a step shape is formed on the upper portion of the case placement portion 55.

The hollow portion 67 has a substantially cylindrical shape (precisely, a truncated cone shape whose inner diameter is reduced upward), and the cross section of the shaft portion 53 has a ring shape with a thickness dimension in the radial direction. Is formed so as to be substantially uniform in each part. The shaft portion 53 is formed with a notch 69 for fitting the shaft portion 53 to a knob (not shown) at the upper portion thereof, but the hollow portion 67 is formed up to a position near the lower portion of the notch portion 69. .

  The slider 80 is formed by forming an elastic metal plate in a substantially ring shape, and a first sliding contact portion 81 and a second sliding contact portion 83 are formed at predetermined positions, and a small size is provided at the predetermined position. A mounting portion 85 made of a hole is formed.

A pair of cover mounting portions 103 made of is provided.

  The cover 130 is made of a metal plate, and is configured by bending side plates 133 and 133 connected to a pair of opposing outer peripheries of a substantially rectangular upper surface plate 131 substantially vertically downward. A cylindrical shaft support portion 135 protruding upward is formed at the center of the upper surface plate 131. In addition, insertion locking portions 137 each having a small hole for fitting the locking portions 17 are formed at positions facing the pair of locking portions 17 of the case 10 in the four corners of the upper surface plate 131. ing. Further, at the positions facing the pair of cover mounting portions 103 of the click plate 100 among the four corners of the upper surface plate 131, mounting portions 139 protruding downward are inserted into the cover mounting portions 103, respectively. ing. Since the mounting portion 139 protrudes downward in a convex shape, the mounting portion 139 is a concave portion on the upper surface side of the upper surface plate 131.

  The side plate 133 has a substantially rectangular shape, and is provided with other member mounting portions 141 that protrude downward in the center of the lower side, and downward on the left and right sides of the lower side. A case mounting portion 143 that protrudes like a tongue is provided.

  Next, a method for assembling the rotary electronic component 1 will be described. First, the slider 80 is disposed on the lower surface of the rotating body main body 51 in advance, and at this time, the small protrusion 63 on the lower surface of the rotating body 50 is inserted into the mounting portion 85 of the slider 80, and the tip thereof is heat caulked to rotate. The slider 80 is fixed to the body 50. On the other hand, the click plate 100 is disposed on the lower surface of the upper surface plate 131 of the cover 130, and at that time, the pair of attachment portions 139 of the cover 130 are inserted into the pair of cover attachment portions 103 of the click plate 100. The click plate 100 is attached in an electrically connected state to the lower surface of the upper surface plate 131 of the cover 130 by crimping.

  Then, the rotating body main body 51 of the rotating body 50 to which the slider 80 is attached is housed in the rotating body housing recess 13 of the case 10, and the lower surface of the case mounting portion 55 is then placed on the rotating body mounting portion 25 of the case 10. Abuts and rests on the top surface.

  Next, the cover 130 is put on the case 10, and the shaft portion 53 of the rotating body 50 is inserted into the shaft support portion 135 of the cover 130 at that time. The upper surface plate 131 of the cover 130 is brought into contact with the upper surface of the case 10, and at this time, both end portions of the click plate 100 are accommodated in the click plate insertion portion 19 of the case 10, and the locking portion 17 of the case 10 is inserted into the cover 130. It is inserted into the locking portion 137 and positioned. At this time, both side plates 133 and 133 of the cover 130 abut against the opposing outer peripheral side surfaces of the case 10 exactly. And if the front-end | tip part of each case attaching part 143 of the cover 130 is bend | folded to the lower surface of the case 10 and the cover 130 and the case 10 are integrated, the rotary electronic component 1 will be completed. When the rotating body 50 is rotated, the slider 80 slides on the sliding contact pattern 31 of the flexible circuit board 30, and the electrical output between the terminal boards 45 changes. The above assembling procedure is an example, and it goes without saying that the assembly may be performed using other various assembling procedures.

  As described above, the rotary electronic component 1 projects the shaft 53 from the upper surface of the case 10 having the rotating body housing recess 13 and the rotating body main body 51 housed in the rotating body housing recess 13 of the case 10. A rotating body 50, a cover 130 covering the upper portion of the case 10 housing the rotating body main body 51, and an inner bottom surface of the rotating body housing recess 13 of the case 10 (in this embodiment, a flexible circuit board insert-molded in the case 10) 30) and an electrical functional part (slider 80 and sliding contact pattern 31) which is installed between the rotary body main body 51 and changes the electrical output by the rotation of the rotary body main body 51. The shaft portion 53 of the rotator 50 is pivotally supported on the shaft support portion 135 provided at 130, and the case mounting portion 55 protruding from the outer periphery of the rotator main body portion 51 is provided in the case 10. By mounting on the rotating body mounting portion 25 provided around the recess 13, the entire surface of the rotating body main body 51 facing the inner bottom surface of the rotating body housing recess 13 of the case 10 is separated from the inner bottom surface. Installed and configured.

  That is, according to the rotary electronic component 1, the rotating body 50 is supported only by the shaft support portion 135 provided on the cover 130, so that the rotating body rotation that occurs when the rotating body 50 is supported at two locations. Torque unevenness can be prevented. Further, since the synthetic resins do not slidably contact each other in the vicinity of the electrical function portion, static electricity does not enter the electrical function portion, and noise can be prevented. In addition, since the case mounting portion 55 of the rotating body main body 51 is mounted on the rotating body mounting portion 25 of the case 10, the pressure breakage prevention strength when the rotating body 50 is pressed from the upper side is easily and strongly maintained. can do.

  In addition, the rotary electronic component 1 is formed by bending the upper plate 131 having the shaft support portion 135 and a pair of outer peripheral portions of the upper plate 131 opposed to each other, the cover 130 being made of metal. A pair of side plates 133 and 133 are provided. On the other hand, around the shaft portion 53 on the upper surface of the rotating body main body 51, around the shaft support portion 135 on the lower surface of the upper surface plate 131 of the cover 130. A cover abutting portion 57 to be abutted is provided, and the lower surface of the upper plate 131 of the cover 130 is made of a metal that elastically contacts a click portion 59 formed on the upper surface of the case mounting portion 55 of the rotating body main body 51 to generate a click feeling. The click plate 100 is installed, and the click plate 100 has a band shape, and is formed on the lower surface of the upper surface plate 131 so as to be along one side where the side surface plates 133 and 133 of the upper surface plate 131 of the cover 130 are not provided. It is mounted in a state of mind connected.

  The rotary electronic component 1 has the above-described configuration, that is, the belt-like (linear) click plate 100 is installed on the lower surface on one side so as to be along one side where the side plates 133 and 133 of the upper surface plate 131 of the cover 130 are not provided. In addition, since the click plate is not formed so as to surround the shaft portion 53 as in the conventional case, the click plate 100 should be installed even if the width dimension between the side plates 133 and 133 is reduced. Therefore, it is not necessary to reduce the diameter of the cover contact portion 57 of the rotating body main body 51, and the width dimension L2 of the cover contact portion 57 can be kept large. The cover abutting portion 57 is a portion that abuts against the lower surface of the upper surface plate 131 of the cover 130 and prevents the rotating body 50 from coming off upward, so that the strength of preventing the rotating body 50 from falling out can be strongly maintained by the above configuration. Even if the width dimension between the side plates 133 and 133 is reduced, it is not necessary to reduce the width dimension of the click plate 100, so that the strength of the click plate 100 can be kept strong.

  Further, according to the rotary electronic component 1, the case mounting portion 55 of the rotating body main body 51 is mounted on the rotating body mounting portion 25 of the case 10, so that the case mounting portion 55 rotates the case 10. It can be formed in a dimension that protrudes outward from the body housing recess 13. That is, in this embodiment, by providing the case 10 with the recess 23, the case mounting portion 55 of the rotating body main body 51 protrudes into the recess 23. For this reason, the outer diameter of the rotating body main body 51 can be increased, the width L2 of the upper surface of the cover contact portion 57 can be increased, and the strength of preventing the rotor from coming off can be increased.

  Further, since the metal click plate 100 is attached in a state of being electrically connected to the metal cover 130, the case mounting portion 55 of the rotating body 50 and the rotating body of the case 10 that are located in the vicinity of the click plate 100 are attached. Static electricity generated by the sliding portion between the mounting portion 25 easily enters the click plate 100. Of course, static electricity generated between the case placement portion 55 and the rotating body placement portion 25 directly enters the cover 130. For this reason, it can prevent more reliably that static electricity penetrate | invades into an electrical function part, and can generate | occur | produce noise more reliably.

  Further, as described above, in the rotary electronic component 1, at least the inner portion of the shaft portion 53 of the rotating body 50 that is pivotally supported by the shaft support portion 135 of the cover 130 is formed in a hollow shape (transverse ring shape). However, with this configuration, the thickness of each part in the cross section of the shaft part 53 can be reduced almost uniformly over the entire circumference. For this reason, when the rotating body 50 is molded by a mold, the amount of contraction when the heated and melted synthetic resin contracts in the mold can be reduced, and at the same time, the amount of contraction of each part can be equalized. For this reason, it is possible to prevent a dent (so-called “sink”) caused by shrinking of the surface of the shaft portion 53 at the time of curing, and to improve the shaft roundness. As a result, torque unevenness during rotation of the rotating body can be prevented. Further, the torque at the time of rotating the rotating body can be maintained at an optimum torque, and it is possible to prevent the rotation from becoming difficult or the backlash from occurring.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea described in the claims and the specification and drawings. Is possible. Note that any shape, structure, or material not directly described in the specification and drawings is within the scope of the technical idea of the present invention as long as the effects and advantages of the present invention are exhibited. For example, in the above embodiment, the flexible circuit board 30 is used as a circuit board to be insert-molded in the case 10, but a rigid circuit board may be used instead of the flexible circuit board 30. Alternatively, instead of insert-molding the circuit board in the case 10, the metal plate may be insert-molded so that the surface of the metal plate is exposed on the inner bottom surface of the rotating body housing recess 13 of the case 10, and the surface of the metal plate may be used as a direct sliding pattern. good. The electrical function unit is not limited to the above structure, and may be, for example, a structure in which a slider is fixed on the case 10 side and a sliding contact pattern is formed in which the slider slides on the rotating body 50 side. Any structure may be used as long as it is an electrical functional unit that changes electrical output by 50 rotations. Moreover, the terminal board 45 does not necessarily need to be installed.

  In the above-described embodiment, the click plate 100 is a linear strip shape, but may be a curved strip shape (for example, an arc shape). In short, the click plate 100 is a strip shape, and the side plates 133 and 133 of the upper surface plate 131 of the cover 130 are formed. Any shape and size that can be installed on the lower surface of one side that is not provided may be used.

  Moreover, in the said embodiment, although it formed in the cross-sectional ring shape by providing the hollow part 67 with a circular cross section in the internal part currently supported by the shaft support part 135 of the cover 130 of the shaft part 53 of the rotary body 50, it is formed in the cross-sectional ring shape. The shape of the part 67 is not limited to a circular cross section as in this embodiment shown in FIG. 9 (a), but as shown in FIGS. 9 (b), (c) and (d). The surface may be other various shapes such as a quadrangular shape, a pentagonal shape, a polygonal shape such as a hexagonal shape, or the like, and may be any shape as long as it has a cross-sectional ring shape.
