Definitions
- This invention relates to a click mechanism for an electronic component.
- the present invention relates to a technique for giving a strong torque feeling and a strong click feeling to a variable resistor click mechanism that opens and closes a switch and changes a resistance value by rotating a rotating shaft.
- variable resistors used in portable electronic devices are required to be downsized, operation knobs used in the variable resistors are enlarged in order to improve operability. For this reason, the variable resistor is required to have a high sliding torque to prevent erroneous rotation and a high step torque to clarify the operation feeling.
- a click spring P1 that produces a feeling of torque and click by sliding with a click plate and a stopper P2 that rotates the click spring P1 together with the rotation of the rotating shaft are coupled as shown in FIGS. 10A and 10B.
- a stopper P2 that rotates the click spring P1 together with the rotation of the rotating shaft
- the click spring P1 and the stopper P2 are coupled by inserting the projection P2a of the stopper P2 into the through hole P1a of the click spring P1 and plastically deforming the tip of the projection P2a by heat caulking or the like.
- the coupling force between the click spring P1 and the stopper P2 is weak and the reaction force of the click spring P1 cannot be increased only by plastic deformation of the tip of the projection P2a. Therefore, it is difficult to realize a high sliding torque and a high step torque.
- the extending portion extending from the annular portion of the click spring is engaged with the pressing portion of the stopper.
- the click spring is about to tilt with the stopper as a fulcrum by pressing the click plate against the pressing portion, but the pressing portion suppresses the tilting by pressing the extending portion.
- the reaction force of the click spring can be strengthened, and higher sliding torque and higher step torque can be realized than before.

- the base portion 2 b has a projection 2 b for receiving the projection 9 b and the flange 12 of the housing 9, a hole 6 e of the click plate 6, and a projection 2 e inserted into the hole 7 c of the torque plate 7.
- a male screw is cut on the outer periphery of the cylindrical portion 2c, and the variable resistor can be fixed by screwing into the female screw provided at a place where the male screw is to be fixed.
- the rotary shaft 1 is composed of three cylindrical bodies having different diameters and is made of resin or metal.
- a portion of the outer peripheral surface of the narrow-diameter portion 1a which is a cylindrical body having the smallest diameter, is cut out along the axial direction. In this example, planes parallel to each other are provided at positions that are 180 degrees from each other.
- the sliding portion 1b which is a cylindrical body having the next smallest diameter, slides with the peripheral surface of the through hole 2a by the rotation of the rotating shaft 1 after the rotating shaft 1 is inserted into the bearing 2.
- a concave portion 1d is provided at a position near the narrow-diameter portion 1a of the sliding portion 1b.
- the knob portion 1c which is a cylindrical body having the largest diameter, has a part of the outer peripheral surface cut out along the axial direction. In this example, planes parallel to each other are provided at positions that are 180 degrees from each other.
- An operation knob (not shown) for rotating the variable resistor is attached to the knob portion 1c.
- FIG. 4A A plan view of the click spring 5 is shown in FIG. 4A, a front view is shown in FIG. 4B, and a bottom view is shown in FIG. 4C.
- the click spring 5 includes an annular portion 5a having a pressing portion 5c and a through-hole 5d and elastically deformable, and an extending portion 5e extending from the annular portion 5a.
- the annular portion 5a is bent at the line L1, and is slightly bent at the line L2 in the direction opposite to the bending at the line L1.

- Two through holes 5d are provided in the wide portion 5b.
- the two through holes 5d are positioned symmetrically with respect to a line connecting the extending portion 5e and the pressing portion 5c. Providing the through holes 5d symmetrically in this way improves the balance and increases the reliability as a variable resistor.

- An arcuate positioning portion 4d is formed so as to protrude on the one plate surface of the base 4a and around the shaft portion 4b. Further, two protrusions 4g corresponding to the two through holes 5d of the click spring 5 are provided on the one plate surface of the base body 4a. The diameter of the cylindrical protrusion 4g is slightly smaller than the diameter of the through hole 5d.
- the base 4a is provided with a substantially rectangular opening 4e extending from one plate surface to the other plate surface.
- a pressing portion 4f extending along the longitudinal direction of the opening 4e is formed so as to protrude adjacent to the opening 4e.
- FIG. 6A shows a perspective view of the state in which the click spring 5 and the stopper 4 are combined
- FIG. 6B shows a cross-sectional view.
- the two protrusions 4 g of the stopper 4 are inserted into the through holes 5 d of the click spring 5, respectively, and the extending portion 5 e of the click spring 5 is engaged with the opening 4 e of the stopper 4.
- Both end portions 4h of the arc-shaped positioning portion 4d engage with the wide portion 5b of the click spring 5, respectively.
- positioning in the rotation direction is performed.
- a portion where the through hole 5 d of the annular portion 5 a of the click spring 5 is in contact with the base body 4 a of the stopper 4.
- the portion where the pressing portion 5c of the annular portion 5a of the click spring 5 is not in contact with the stopper 4, and the portion closer to the pressing portion 5c is located away from the surface of the base 4a.
- the click plate 6 (FIG. 1) has an opening 6a slightly larger than the click spring 5 in the center.
- the click plate 6 is provided with a protrusion 6b that protrudes toward the center of the opening 6a.
- the protrusion 6b is provided with a hole 6c.
- the click plate part 6 has fixing holes 6d at four corners, and has a long hole 6f that connects two mounting holes 6e.
- the torque plate part 7 has an opening 7a slightly larger than the shaft part 4b of the stopper 4 at the center part. Similarly to the click plate portion 6, the torque plate portion 7 has fixing holes 7b at the four corners, and has a long hole 7d that connects the two mounting holes 7c.
- the click plate 13 is configured by overlapping the click plate portion 6 and the torque plate portion 7.
- the protruding portion 6 b and the hole 6 c of the click plate portion 6 constitute an uneven portion on one plate surface of the torque plate portion 7.
- the click plate 13 is placed on the bearing 2 in such a direction that the closer to the stopper 4 becomes the click plate portion 6, and the protruding portion 2e is inserted into the hole 6e and the hole 7c.
- the first variable resistor portion 14 and the second variable resistor portion 15 are stacked on the click plate 13.
- the first variable resistor section 14 includes a housing 9 that houses an insulating substrate 9a (FIG. 3), and a rotating body 8 provided with sliding contacts 8a. A current collector and a resistor are formed on the insulating substrate 9a. The position where the sliding contact 8a contacts the current collector and the resistor is determined according to the rotation angle of the rotating body 8, and the resistance value of the first variable resistor section 14 is determined according to this position. An extraction terminal 9b is connected to each of the current collector and the resistor, and is taken out to the outside.
- the second variable resistor unit 15 includes the housing 11 and the rotating body 10 and has the same configuration as that of the first variable resistor unit 14, and thus description thereof is omitted.
- the click plate 13 sandwiches the click spring 5 together with the stopper 4 and is pressed by the click plate 13 so that the click spring 5 is elastically deformed in the direction in which the pressing portion 5 c approaches the stopper 4. .
- the click plate 13 is pressed against the pressing portion 5c, the click spring 5 tilts with the stopper 4 serving as a fulcrum (in this example, the portion where the stopper 4 contacts the line L1 (FIG. 4) of the click spring 5).
- the pressing portion 4f of the stopper 4 suppresses the tilting by pressing the extending portion 5e.
- the reaction force of the click spring 5 can be made stronger than before by suppressing the tilting of the click spring 5 by pressing the extending portion 5e with the pressing portion 4f instead of plastic deformation due to heat caulking or the like.
- the force with which the click spring 5 presses the click plate 13 can be made stronger than before. Therefore, it is possible to realize a torque feeling and a click feeling stronger than before.
- the reaction force of the click spring 5 can be further strengthened.
- the distance between the position of the line L1 that is a fulcrum and the position where the pressing portion 4f presses the extending portion 5e can be increased. This is because tilting can be suppressed with a small force.
- the stopper 4 and the click spring 5 also rotate according to the rotation of the rotating shaft 1, when the rotating shaft 1 is rotated slowly, the pressing portion 5c also slowly rides on the protruding portion 6b and slowly falls from the protruding portion 6b.
- the stopper P2 and the click spring P1 are fixed by plastically deforming the tip end portion of the protrusion P2a, and the click spring P1 cannot move freely with respect to the stopper P2. When it is turned, the click sound and the click feeling produced may not be clear.
- the protrusion 4g of the stopper 4 and the through hole 5d of the click spring 5 are not fixed by plastic deformation such as heat caulking.
- the protrusion 4g is merely loosely fitted in the through hole 5d, and the click spring 5 can move more freely with respect to the stopper 4 than in the prior art. Therefore, the click spring 5 can move alone and collide with the torque plate portion 7 only when the pressing portion 5c of the click spring 5 is hooked to the hole 6c to some extent or is only somewhat disengaged from the outside of the protruding portion 6b. Therefore, even when the rotating shaft 1 is rotated slowly, the generated click sound and click feeling can be clarified.
- the protrusion 4g of the stopper 4 is not plastically deformed by heat caulking or the like, a plastic deformation step is not required, and the manufacturing cost can be reduced. Further, since the material of the stopper 4 is not limited to a material that can be plastically deformed, the room for selecting the material of the stopper 4 is widened, and the stopper 4 can be formed by a metal injection mold (MIM).
- MIM metal injection mold
- the extending portion 5e may be extended in one direction from the annular portion 5a without being bent into a crank shape.
- the extending portion 5e may be extended on the same plane as the wide portion 5b.
- the pressing portion 4f of the stopper 4 is positioned such that the surface where the pressing portion 4f contacts the extending portion 5e is separated from the upper surface of the base 4a by the thickness of the click spring 5.
- the upper surface of the pressing portion 4f may be the same height as the surface of the base 4a.
- the annular portion 5a may be extended in one direction from the annular portion 5a without being bent along the line L1 and without extending the extending portion 5e into a crank shape.
- the pressing portion 4f and the extending portion 5e are in contact with each other obliquely with respect to a plane perpendicular to the axial direction of the rotating shaft 1.
- the click spring 5 is stably held by the stopper 4 when the area of the portion where the stopper 4 and the annular portion 5 a of the click spring 5 are in contact with each other is increased. Reduces failure and increases reliability.
- the click mechanism A according to the present invention can be used for electronic components other than variable resistors, for example, rotary switches.
- the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the gist of the present invention.
