Description

  The present invention relates to a click mechanism used for a rotary electronic component.

  Conventionally, for example, as shown in FIG. 2 of Patent Document 1, a rotary electronic component with a click function rotates a rotary type object (31) of a knob (30) in a storage part of a switch board (60). The click spring member (20) is installed on it freely, and the top is covered with a cover (10). The click spring member (20) is configured by forming a ring-shaped click spring (22) inside the frame-shaped fixing portion (21), and an elastic contact portion (provided on the click spring (22)) ( 24) is brought into elastic contact with the concavo-convex portion (35) provided on the rotary mold (31), and the knob (30) is rotated so that a click sensation is obtained. The fixing portion (21) of the click spring member (20) is sandwiched and fixed between the upper surface of the switch board (60) and the cover (10).

JP 2005-78844 A

  However, since the conventional click spring member (20) has a shape in which the frame-shaped fixing portion (21) surrounds the ring-shaped click spring (22), its area is large, and the cost of the material cannot be reduced. . On the other hand, if the fixing portion (21) is omitted in order to reduce the material cost, it is difficult to reliably position and fix the click spring member (20).

  In order to change the click sensation (the strength) generated when the knob (30) rotates, the thickness of the click spring member (20) is changed to change the elasticity of the elastic contact portion (24) of the click spring (22). In some cases, the height dimension of the rotary electronic component changes by the changed thickness. When the thickness of the click spring member (20) is reduced, when the electronic component foot (15) is inserted into the mounting hole provided in the hard circuit board, the bent portion provided in the vicinity of the tip of the foot (15) and the circuit board A gap is generated between the back surface and the backlash. Further, when the thickness of the click spring member (20) is increased, the bent portion of the foot (15) comes into contact with the inside of the mounting hole of the circuit board, which causes a disadvantage that it cannot be firmly inserted into the circuit board. Further, the foot (14) of the cover (10) is placed on the lower surface side of the switch board (60) so as to fix the switch board (60) and the cover (10) in accordance with the click spring member (20) having a preset thickness. For example, if the click spring member (20) is thinned when the bending is set, the clamping force of the click spring member (20) between the switch board (60) and the cover (10) becomes small. There was also a risk of rattling.

  The present invention has been made in view of the above-mentioned points, and the object thereof is to reduce the material cost, and at the same time, the click spring can be surely positioned and fixed, and the click springs of different thicknesses can be securely clamped and fixed. It is to provide a click mechanism for a rotary electronic component.

Further, a locking hole 111 made up of a small hole for inserting and locking the locking claw 79 substantially closely is provided at a position of the case main body 101 facing the two locking claws 79 of the click spring 70. .

  The knob 120 is formed by molding synthetic resin into a substantially cylindrical shape and having a size that can be freely inserted into the shaft support portion 107 of the cover 100. A small-diameter cylindrical protrusion 121 is formed from the lower surface of the knob 120. A substantially rectangular locking portion 123 protrudes from the outer periphery near the lower end of the protruding portion 121 in a direction different by 180 °. The pair of locking portions 123 can be inserted into the pair of protruding portions 54 of the knob mounting hole 53 of the rotating body 50, and the upper portion of the locking portion 123 is formed to have a size and shape that can be inserted into the groove 55. Yes. The lower end surface of the protruding portion 121 is a pressing portion 125 protruding in a spherical shape.

  In order to assemble the rotary electronic component 1, the slider 65 is installed in advance on the slider mounting surface 57 of the rotating body 50, and at that time, the slider mounting portion 59 of the rotating body 50 is attached to the mounting portion of the slider 65. 69, the tip of each slider attachment portion 59 is heat caulked, and thereby the slider 65 is fixed to the rotating body 50. On the other hand, the protrusion 121 of the knob 120 is inserted into the knob mounting hole 53 of the rotating body 50 from the upper side, and the entire locking portion 123 at the tip protrudes below the protruding portion 54 of the rotating body 50, and in this state ( The knob 120 is rotated by 90 ° (with the entire locking portion 123 exposed below the protruding portion 54), and the knob 120 is lifted upward so that the upper surface side portion of the locking portion 123 is the groove portion of the rotating body 50. 55 is engaged.

  Then, the reverse plate 45 is stored in the reverse plate storage portion 27 of the case 10. The reversing plate 45 and the pressing switch switch pattern 31 of the flexible circuit board 30 constitute a basic structure of the pressing switch.

  Next, the rotating body 50 to which the slider 65 and the knob 120 are attached is inserted into the housing portion 13 of the case 10. At this time, each sliding contact portion 67 of the slider 65 comes into contact with the rotation switch switch pattern 33. The slider 65 and the rotary switch switch pattern 33 constitute a basic structure of a rotary switch (rotary electronic component).

  Next, the click spring 70 is placed on the rotating body 50. At this time, both attachment portions 75 of the click spring 70 are housed and positioned in the click spring locking portion 24 of the case 10 respectively. At the same time, the elastic contact portion 73 of the click spring 70 is in elastic contact with the click engagement portion 61 of the rotating body 50.

  Next, the cover 100 is put on the click spring 70, and at that time, the knob 120 and the shaft portion 51 of the rotating body 50 are inserted into the shaft support portion 107 of the cover 100, and at the same time, the case 10 is put on the locking portion 109 of the cover 100. The positioning locking portion 29 is inserted, and at the same time, the locking claw 79 of the click spring 70 is inserted and locked in the locking hole 111 of the cover 100 to position the click spring 70. Then, the case locking portion 103 of the cover 100 is bent and integrated to the bottom surface side of the case 10. Thereby, the rotary electronic component 1 is completed. The above assembling procedure is an example, and it goes without saying that the assembly may be performed using other various assembling procedures.

  Here, the operation of the clamping protrusion 241 of the case 10 will be described. As shown in FIG. 7, when the attachment portion 75 of the click spring 70 is housed in the click spring locking portion 24 of the case 10, the attachment portion 75 is placed on the clamping protrusion 241. At this time, the entire attachment portion 75 is not housed in the click spring locking portion 24, but a part in the thickness direction is exposed above the click spring locking portion 24. In other words, the dimension of each member is set so that a part (upper part) of the attachment portion 75 in the thickness direction is exposed above the click spring locking portion 24. When the cover 100 is placed on the case 10 and attached so as to press the cover 100 against the case 10 as shown in FIG. 6, the attachment portion 75 is sandwiched between the cover 100 and the sandwiching projection 241. Due to this clamping force, the clamping protrusion 241 (particularly in the vicinity of its tip) is deformed, whereby the lower surface of the cover 100 abuts (or is located close to) the upper surfaces of the outer peripheral side walls 17 to 23 of the case 10. In other words, the sandwiching projection 241 absorbs the thickness of the mounting portion 75 projecting from the upper surfaces of the outer peripheral side walls 17 to 23 of the case 10 by being deformed.

  On the other hand, when the thickness of the click spring 70 is changed (for example, when it is made thin) for reasons such as changing the resilience of the click spring 70, the thickness of the attachment portion 75 is also reduced as shown in FIG. However, in this case as well, a part (upper part) of the attachment portion 75 in the thickness direction is exposed above the click spring locking portion 24, so that the click spring 70 is deformed by the deformation of the holding projection 241 as described above. Can be securely clamped and fixed. The same applies when the thickness of the click spring 70 is increased. That is, even if the thickness of the click spring 70 is changed, only the dimension protruding above the click spring locking portion 24 is different, and the dimension of the protruding portion is absorbed by the different deformation of the clamping projection 241. The click spring 70 can be securely clamped and fixed, and the height dimension between the case 10 and the cover 100 can be kept the same.

  Next, the operation of the rotary electronic component 1 will be described. That is, when the knob 120 is rotated, the rotating body 50 and the slider 65 are rotated integrally therewith, the sliding contact portion 67 of the slider 65 is slid on the rotary switch switch pattern 33, and the output is changed. . The output is taken out from three terminals 40 protruding in the same direction. At the same time, a click sensation is generated by the elastic contact portion 73 of the click spring 70 elastically contacting the click engagement portion 61 of the rotating body 50 rotating. On the other hand, when the knob 120 is pressed downward, the rotary body 50 remains in its original position, and only the knob 120 is lowered, and the pressing portion 125 presses and reverses the reversing plate 45, whereby the switch pattern 31 for the press switch. The two switch patterns constituting the are electrically connected and turned on. The output is taken out from two terminals 40 protruding in the same direction. At this time, the locking part 123 of the knob 120 is also lowered together with the knob 120. However, the dimensions of the respective parts are set so as not to be disengaged from the groove part 55 of the rotating body 50 even when the locking part 123 is lowered. However, only the knob 120 does not rotate. When the pressure on the knob 120 is released, the reversing plate 45 automatically returns to its original shape by the elastic restoring force of the reversing plate 45, whereby the pressure switch is turned off, and at the same time, the knob 120 is pushed up to the original position automatically. Return.

  As described above, according to the rotary electronic component 1, the click spring 70 is protruded from the outer periphery of the arm portion 71 stored in the storage portion 13 of the case 10 and the click spring of the case 10 is locked. The click spring 70 can be configured with a small area because the mounting portion 75 is inserted and positioned in the portion 24, and the material cost can be reduced. In addition, since the attachment portion 75 of the click spring 70 is inserted and positioned in the click spring locking portion 24 of the case 10, and this attachment portion 75 is sandwiched and fixed between the case 10 and the cover 100, Fixing is easy and reliable. Thus, by inserting the attachment portion 75 of the click spring 70 into the click spring locking portion 24 of the case 10, the click spring 70 can be reliably positioned in the rotational direction, but the radial positioning is not necessarily reliable. I can't say that. For this reason, in this rotary electronic component 1, the locking claw 79 of the click spring 70 is inserted and locked into the locking hole 111 of the cover 100, and thereby the click spring 70 is rotated in both the rotational direction and the radial direction. Positioning is ensured.

  In addition, since the click protrusion 241 that absorbs the difference in the thickness dimension of the attachment portion 75 by deforming when the attachment portion 75 of the click spring 70 is held on the bottom surface of the click spring locking portion 24 of the case 10 is provided, Even if the thickness of the click spring 70 is changed for reasons such as changing the elastic force of the click spring 70, the click spring 70 can be securely held and fixed. At that time, the height dimension between the case 10 and the cover 100 does not change. Further, like the click spring 70 of the rotary electronic component 1, the click spring 70 is formed in a ring shape in which the root portions of a pair of arc-shaped arm portions 71 are connected by a pair of mounting portions 75, and a pair of mounting portions. If the 75 is sandwiched and fixed between the case 10 and the cover 100, the click spring 70 can be fixed more reliably.

  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 rotary electronic component 1, the click spring 70 is formed in a ring shape by a pair of arm portions 71 and a pair of mounting portions 75, and each arm portion 71 is provided with an elastic contact portion 73. As shown in FIG. 9, the elastic contact portion 73 may be provided only on one arm portion 71 to constitute the click spring 70-2, and one arm portion 71 is omitted as shown in FIG. The click spring 70-3 may be constituted by the portion 71 and the two attachment portions 75, and one of the attachment portions 75 is omitted as shown in FIG. 11, and the two arc-shaped arm portions 71 and one attachment portion are provided. 75 may constitute the click spring 70-4. Further, the arm portion 71 not provided with the elastic contact portion 73 shown in FIG. 9 may be formed in a shape other than an arc shape (in this example, a linear shape) as indicated by a dotted line. That is, the click spring may be formed in a ring shape or an arc shape in which the attachment portion 75 is connected to the root portion of the arc-shaped arm portion 71.

  Moreover, although the said rotary electronic component 1 is a rotary electronic component with a press switch, it cannot be overemphasized that this invention is applicable also to the rotary electronic component which abbreviate | omitted the press switch. In this case, the rotating body 50 and the knob 120 are integrally formed, and the respective components constituting the push switch are omitted. The rotary electronic component 1 is a rotary switch, but may be configured as a rotary variable resistor by changing a pattern or the like.

  Also, the shape and structure of the sandwiching protrusion 241 can be variously modified. For example, it may not be formed over the entire length in the longitudinal direction of the bottom surface of the click spring locking portion 24. A protruding shape, a shape protruding in one or a plurality of kamaboko shapes, and the like may be used, and various modifications are possible. In addition, the clamping protrusion 241 is integrally formed with the case 10 in the above embodiment, but only the clamping protrusion 241 is created as a separate part with rubber or the like, and this is attached to the bottom surface of the click spring locking part 24. Also good. In short, the structure that absorbs the difference in thickness of the mounting portion 75 by deforming the mounting portion 75 of the click spring 70 between the case 10 and the cover 100 on the bottom surface of the click spring locking portion 24 of the case 10. Any configuration may be used.
