Description

  The present invention relates to a rotary electronic component having a configuration in which an electrical output of an electrical functional unit changes with rotation of a rotating body.

  Conventionally, a mounting member, a rotating body that is rotatably installed with respect to the mounting member, and an electrical function unit that is installed between the mounting member and the rotating body and whose electrical output changes as the rotating body rotates. (For example, refer to Patent Document 1). The rotary electronic component includes a sliding contact pattern provided on the attachment member side as the electrical function portion and a slider attached to the rotating body, and contacts provided on the slider as the rotating body rotates. The portion is configured to be in sliding contact with the sliding contact pattern so that the electrical output of the sliding contact pattern changes. Further, the rotating body incorporates a coil spring comprising a coil portion wound in the shape of a coil installed at the rotation center position of the rotating body and a drawing portion drawn out radially outward from the coil portion. When the coil rotates, the pulling part of the coil spring is locked by the pulling part locking part provided on the mounting member side, so that an elastic return force is generated in the coil part, and the rotating body automatically returns to the neutral position. is doing.

However, in the above-described conventional rotary electronic component, the lead-out portion locking portion is disposed at a position (outside position) farther from the rotation center of the rotating body than the contact portion of the slider. The part was disposed at a position close to the rotation center of the rotating body. For this reason, the resolution when the contact portion slides on the sliding contact pattern cannot be increased, and it is necessary to increase the rotation angle of the rotating body, and accordingly, the rotating electronic component cannot be reduced in size and thickness. was there. In addition, if the lead part between the coil part of the coil spring and the lead part locking part becomes long, the deflection of the lead part becomes excessive when the rotating body is rotated, and the rotating body is returned to the neutral position. There was a risk of slow response. Moreover, when the drawer | drawing-out part latching | locking part is arrange | positioned in the outer side position of the contact part of a slider, there existed a problem that the size reduction of the external dimension of a rotation type electronic component could not be achieved.

Further, when the drawing portion 62 is pushed up by the contact portion 40a, the drawing portion 62 is also pushed up by the contacting portion 42a.

  In the rotary electronic component 1, as described above, the drawing portion locking portion 28 is positioned closer to the rotation shafts 31 and 32 (rotation center of the rotation body 30) of the rotation body 30 than the contact portion 53 of the slider 50. It is arranged. As a result, the external dimensions of the rotary electronic component 1 can be reduced (specifically, the width dimension in the direction orthogonal to the rotation axis direction of the rotary electronic component 1). Moreover, since the drawer | drawing-out part latching | locking part 28 can be arrange | positioned close to the coil part 61 of the coil spring 60, while the drawer | drawing-out part 62 between the drawer | drawing-out part latching | locking part 28 and the coil part 61 does not have a possibility of bending. The spring return force of the coil spring 60 that is generated when the drawing portion 62 is locked by the drawing portion locking portion 28 can be increased. Further, by arranging the drawing-out portion locking portion 28 at a position closer to the rotation shafts 31 and 32 of the rotating body 30 than the contact portion 53 of the slider 50, the contact portion 53 of the slider 50 is accordingly rotated. Since it can arrange | position in the position away from 30 rotating shafts 31 and 32, the resolution | decomposability at the time of the contact part 53 of the slider 50 slidingly contacting on the sliding contact pattern 13 can be improved. As a result, the rotation angle of the rotator 30 can be reduced, so that the rotary electronic component 1 can be reduced in size and thickness.

  Further, the rotating body 30 is formed in a rectangular shape whose longitudinal direction is the direction orthogonal to the rotating shaft direction of the rotating body 30, so that the height of the rotating body 30 (the upper portion of the rotating shafts 31, 32 and the lower side thereof) (Thickness dimension of the portion) can be made smaller than before, so that the thickness of the rotary electronic component 1 can also be reduced. Further, the contact portions 53 of the sliding contact pattern 13 and the slider 50 are arranged at positions near the both ends in the longitudinal direction of the rotating body 30, respectively. Can be arranged at a position as far as possible from the rotation center of the rotating body 30, so that the resolution when the contact portion 53 is in sliding contact with the sliding contact pattern 13 can be further increased. Thereby, since the rotation angle of the rotary body 30 can be made smaller, the rotary electronic component 1 can be reduced in size and thickness. Further, since the slider 50 is formed with the rectangular main body 51, the slider 50 can be easily attached to the rectangular rotating body 30 and cannot be easily detached from the rotating body 30. . In addition, the slider 50 can be arranged with the contact portion 53 at a position near the both ends in the longitudinal direction of the rotating body 30 with a simple configuration.
