  FIG. 3 is a perspective view of the sliding mold 30 as viewed from above. As shown in FIGS. 2 and 3, the sliding mold 30 is made of a synthetic resin, and is rectangular on the upper surface of the base portion 31 that is substantially flat and rectangular, and is slid more than the base portion 31. The drawing portion contact projection 32 having a short length in the moving direction A is integrally formed. A pair of recesses 34 and 34 are formed by both end surfaces in the A direction of the drawing portion contact protrusion 32 and the top surface of the base portion 31 by making the drawing portion contact protrusion 32 shorter than the base portion 31. is doing. Further, a pair of abutting portions 33 projecting in opposite directions toward the A direction are provided at the end portions on both sides in the A direction of the drawing portion abutting projection 32 on the side away from the coil portions 52 and 52 described below. , 33 are provided. The abutting portions 33 and 33 abut against the drawing portions 53 and 53 of the torsion coil spring 50 described below to press the drawing portions 53 and 53. In the recess 34, the contact portion 33, 33 is disposed on the side close to the coil portions 52, 52 in the recess 34 of the sliding mold 30. Compared with the case where it is provided at the end, the length of the lead-out portions 53, 53 from the coil portions 53, 53 to contact with the contact portions 33, 33 can be increased. When the one abutting portion 33 presses the lead portion 53 and opens the coil portion 52, the amount of change in the movement angle of the root portion of the lead portion 53 can be reduced and the coil portion 52 is opened. The amount can be reduced so that the sliding mold 30 can move to any position. Pot uniform can impart a smooth resilient force. Furthermore, the drawing-out portion protrusion protrusion 32 is provided with insertion holes 35, 35 each having a through hole into which a fixing protrusion 72 of the knob 70 described below is inserted.

  On the other hand, as shown in FIG. 2, a concave slider storage portion 36 is provided on the lower surface of the base portion 31 of the sliding mold 30, and a protruding slider fixing portion 37 and a positioning portion 38 are provided from the bottom surface. Is protruding. Note that the lower portions of the insertion holes 35 are opened in the slider housing portion 36.

  As shown in FIG. 2, the slider 40 is made of an elastic metal plate having conductivity, and two sliding booklets 43, 43 are projected from one end of a flat base 41 and bent downward. It is configured. The base 41 is provided with a fixing hole 44 and a positioning hole 45.

  The torsion coil spring 50 is formed of a metal wire having elasticity with a substantially linear connecting part 51 at the center thereof, and both ends of the connecting part 51 are wound a predetermined number of times to form coil parts 52 and 52. Further, the coil part 52 , 52, the drawing portions 53, 53 are drawn out.

  At this time, the coil portions 52 and 52 are both wound the same number of times (in this embodiment, two and a half times) in the same direction (upward) by reverse rotation, so that the lead-out portions 53 and 53 are both at the same height. They are directed in the same direction (a direction substantially perpendicular to the thickness direction of the coil portion 52 and a direction substantially perpendicular to the connecting portion 51). Thereby, the drawer | drawing-out parts 53 and 53 are formed on the same surface, and it will be in the state which the coil parts 52 and 52 protruded to the one side from the surface. In addition, since the drawer | drawing-out parts 53 and 53 were formed on the same surface, when the sliding mold 30 is slid, the force of the A direction applied to the sliding mold 30 will be located on the same plane, and slide movement will be carried out. It can be done smoothly. On the other hand, a spring position correcting portion 54 is provided at the central portion of the connecting portion 51. The spring position correcting portion 54 is bent in a square shape in the same direction as the winding direction (upward direction) of the coil portions 52, 52. The side surface of the spring position correcting portion 54 abuts on a spring abutting portion 68 of the case 60 described below.

  Next, the case 60 shown in FIG. 2 is formed by molding a synthetic resin into a substantially plate shape. A frame 60a that protrudes downward is formed around the case 60 so that a concave housing is formed on the lower surface of the case 60. Part 61 is formed. In the center of the case 60, a rectangular through hole 62 is provided through which a connecting portion 71 and a fixing projection 72 of the knob 70 described below are inserted and penetrated. Plate-shaped guide walls 63 and 63 are provided on two sides parallel to the sliding direction A of the slider 40 of the through hole 62 on the lower surface of the case 60. The guide walls 63, 63 are provided in such a width that the inner surfaces 63 a, 63 a facing each other are in contact with both side surfaces 30 a, 30 a parallel to the sliding direction A of the sliding mold 30. The guide walls 63 and 63 are slidably housed inside.

  In the vicinity of both ends of one guide wall 63, cylindrical protrusions 64, 64 inserted into the holes 52a, 52a in the center of the coil portions 52, 52 of the torsion coil spring 50 are provided downward from the bottom surface of the case 60. In the vicinity of both ends of the other guide wall 63, locking projections 65, 65 projecting in a columnar shape downward are provided. The diameters of the protrusions 64 and 64 are substantially the same as the diameters of the holes 52a and 52a of the coil portions 52 and 52. By inserting the protrusions 64 and 64 inside the holes 52a and 52a, the torsion coil spring 50 is attached to the case 60. It is supposed to be fixed. In addition, by attaching elastic bodies 66, 66 made of, for example, rubber or synthetic resin to the locking protrusions 65, 65, the drawing portion locking portions 69, 69 are configured.

  Further, projections 67 for fixing the base 10 and the flexible substrate 20 are provided downward from the four corners of the lower surface of the case 60. A spring abutting portion 68 that protrudes from the inner surface of the frame 62 is provided at a position facing the spring position correcting portion 54 when the torsion coil spring 50 is housed and fixed in the case 60. The spring contact portion 68 is an inclined surface whose protruding height increases from the lower side to the upper side of the frame 62.

  Next, the knob 70 is formed by molding a synthetic resin into a substantially flat and rectangular shape, and a connecting portion 71 having a width slightly smaller than the width of the through hole 62 of the case 60 is downwardly formed from the center of the lower surface thereof. The fixing protrusions 72 and 72 having dimensions are inserted so as to protrude from both sides of the lower end surface of the connecting portion 71 and are inserted into the insertion holes 35 and 35 of the sliding mold 30.

  Next, a method for assembling the sliding electronic component 1 will be described. First, the slider 40 is attached in advance in the slider storage portion 36 of the sliding object 30. At that time, the slider fixing portion 37 and the positioning portion 38 are inserted into the fixing hole 44 and the positioning hole 45 of the slider 40, and the tip of the slider fixing portion 37 is fixed by heat caulking.

  On the other hand, the protrusions 64, 64 of the case 60 are fitted into the holes 52 a, 52 a of the coil portions 52, 52 of the torsion coil spring 50, and the torsion coil spring 50 is fixed in the housing portion 61 of the case 60. At this time, the spring position correction portion 54 of the torsion coil spring 50 is brought into contact with the spring contact portion 68 of the case 60 so that the connecting portion 51 is inclined toward the electrical function portion side such as the flexible substrate 20. Twist into. As a result, as shown in FIG. 1, the coil portions 52 and 52 are tilted and fixed with respect to the protrusion 64 by the gap between the inner peripheral surface of the holes 52 a and 52 a of the coil portions 52 and 52 and the outer peripheral surface of the protrusions 64 and 64. As a result, the leading portions 53 and 53 are inclined downward, and the leading end of the leading portion 53 is maintained slightly away from the lower surface of the case 60.

  At this time, the opposing inner portions of the drawer portions 53 and 53 are in contact (elastically contacted) with the drawer portion locking portions 69 and 69 (see FIG. 4A). Note that the width between the lead-out portions 53 and 53 of the torsion coil spring 50 before being fixed in the storage portion 61 is smaller than the width between the lead-out portion locking portions 69 and 69, and the torsion coil spring 50 is inserted into the storage portion 61. The drawer portions 53 and 53 are elastically brought into contact with the drawer portion locking portions 69 and 69 by expanding the space between the drawer portions 53 and 53 once and fixing the drawer portion contact portions 69 and 69 therebetween. It becomes a state. It should be noted that the sliding-type object 30 described below, which is positioned between the two drawing parts 53, 53, is elastically contacted so that the width between the leading ends of the drawing parts 53, 53 is smaller than the width between the coil parts 52, 52. Miniaturization in the A direction can be achieved.

  In FIG. 2, the sliding object 30 with the slider 40 attached is housed inside the guide walls 63, 63 of the case 60 to which the torsion coil spring 50 is attached. As a result, the torsion coil spring 50 is disposed so as to surround the outer periphery of the sliding mold 30 as shown in FIG. Next, the connecting portion 71 of the knob 70 and the fixing protrusions 72, 72 are passed through the through hole 62 of the case 60 from the upper side of the case 60, and the through holes 35, 35 of the sliding mold 30 below the through hole 62. The fixing projections 72 and 72 are passed through, and the tips thereof are caulked with heat to integrate the knob 70 with the sliding mold 30 and the case 60.

  Then, the four protrusions 67 of the case 60 are passed through the through hole 24 of the flexible substrate 20 and the through hole 11 of the base 10, and the tips of the protrusions 67 projecting from the lower side of the through hole 11 are thermally caulked. If fixed integrally, the slide-type electronic component 1 is completed.

  Next, the operation of the sliding electronic component 1 will be described. First, if the knob 70 is slid in the sliding direction A, the sliding mold 30 is slid in the sliding direction A on the inner side of the guide walls 63, 63, whereby the sliding booklet 43 slides on the pattern 23. The output (in this embodiment, the on / off output of the switch) is changed.

  On the other hand, the knob 70 and the sliding mold 30 always attempt to automatically return to the neutral position by the action of the torsion coil spring 50. 4A to 4C are explanatory views of the automatic return operation of the sliding type object 30 to the neutral position by the torsion coil spring 50. FIG. That is, when an operating force is not applied to the sliding mold 30 from the outside, both the drawn portions 53 and 53 of the torsion coil spring 50 are connected to the both drawn portion locking portions 69 of the case 60 as shown in FIG. , 69 are in contact with each other (elastic contact), and at the same time, the drawer contact projections 32 of the slider 30 are located inside the drawers 53, 53 so as to contact both of the contacts 33, 33. As a result, the sliding mold 30 is positioned at the neutral position.

  When the sliding object 30 is slid in one direction A1 as shown in FIG. 4B, one drawer portion (the drawer portion opposite to the A1 direction) 53 becomes the drawer portion locking portion 69. The other drawing portion 53 (the drawing portion on the A1 direction side) 53 is pressed by the contact portion 33 of the sliding object 30 and is separated from the drawing portion locking portion 69 while being in contact with the drawing portion 53 on the A1 direction side. The elastic restoring force to the original shape acts on the, and the automatic restoring force to the neutral position of the sliding mold 30 acts. Therefore, when the operating force applied to the sliding mold 30 is released, the sliding mold 30 automatically returns to the neutral position shown in FIG. When the slide-type object 30 is automatically returned to the neutral position, the drawer portion 53 on the A1 direction side comes into contact with the drawer portion locking portion 69, and the outer periphery of the drawer portion locking portion 69 is constituted by an elastic body 66. Because there is no sound. On the other hand, when the sliding mold 30 is slid in the opposite direction A2 as shown in FIG. 4C, the sliding mold 30 has an automatic return force to the neutral position as described above.

  The slide type electronic component 1 according to the embodiment of the present invention has been described above. In the slide type electronic component 1, the thickness of the torsion coil spring 50, which is a resilient means for automatic return to the neutral position, is set. Since there is only the thickness of the coil parts 52, 52, the thickness can be reduced as compared with the conventional case where a compression coil spring is used.

  In particular, in the sliding electronic component 1, the torsion coil spring 50 and the sliding mold 30 are slid by arranging the torsion coil spring 50 so that the coil portions 52 and 52 are positioned on the side of the sliding mold 50. Since the electronic component 1 is not overlapped in the thickness direction, the slide electronic component 1 can be thinned. Specifically, in the slide type electronic component 1 according to the above-described embodiment, as shown in FIG. 3, the drawer portions 53, 53 are arranged in the concave portions 34, 34 of the sliding type object (moving body) 30, Further, the coil portions 52, 52 projecting from the surface formed by the two lead portions 53, 53 of the torsion coil spring 50 are replaced with the electrical function portions of the sliding object 30 (slider 40, pattern 23 on the flexible substrate 20, etc.). The thickness L ′ of the torsion coil spring 50 is accommodated within the thickness L of the movable body such as the sliding mold 30. Accordingly, the thickness for the torsion coil spring 50, that is, the thickness corresponding to L ′ is reduced as compared with the case where the two are overlapped. Similarly, in the case of L <L ′, the thickness is reduced by L as compared with the case of overlapping. As another embodiment, the lead-out portions 53 and 53 are installed on the electrical function portion side, and the coil portions 52 and 52 are projected in the opposite direction to the electrical function portion (the direction in which the knob 70 is disposed). May be. In short, at least a part of the thickness of the coil parts 52, 52 may be included in the thickness of the sliding mold 30.

  By the way, in the slide-type electronic component 1 according to the above-described embodiment, as shown in FIG. 1, the spring position correcting portion 54 of the torsion coil spring 50 is brought into contact with the spring contact portion 68 of the case 60 to twist the connecting portion 51. The leading portions 53, 53 are slightly inclined downward with respect to the lower surface of the case 60 so that the leading ends of the leading portions 53, 53 are slightly separated from the lower surface of the case 60. This is due to the following reason. That is, as shown in FIG. 1, a slight gap a is formed between the upper surface of the sliding mold 30 and the lower surface of the case 60. There is a risk of entering the gap a. Therefore, as described above, the leading ends of the lead-out portions 53, 53 are tilted downward so as to be slightly away from the lower surface of the case 60, so that the possibility of the lead-out portions 53, 53 entering the gap a is completely eliminated, and always reliably. The contact portion 33 is in contact with the contact portion 33.

  FIG. 5 is a perspective view showing an example of another torsion coil spring 50-2 according to the reference example. This torsion coil spring 50-2 is provided with one coil portion 52-2 in which a wire is wound in a weak coil shape for two turns, and both ends thereof are bent and extended outward in the radial direction to be connected portions 51-2 and 51-2. And both ends of the connecting portions 51-2 and 51-2 are bent at substantially right angles, and the ends thereof are taken as drawing portions 53-2 and 53-2. The torsion coil spring 50-2 is configured such that, in the coil portion 52-2, the lead portions 53-2 and 53-2 at both ends are flush with each other when one wire rod passes over the other adjacent wire rod from the outside (or inside) thereof. (In this embodiment, it is comprised so that it may be located in the lower surface of the coil part 52-2).

  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 claims and the technical idea described in the specification and drawings. Deformation is possible. It should be noted 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 two coil portions 52 of the torsion coil spring 50 are provided, but the number of coil portions may be three or more.

  In the above-described embodiment, the elastic body 66 is attached to the outer periphery of the locking projection 65 to mute the sound so as to configure the drawer portion locking portion 69. However, the elastic body 66 is omitted and only the locking projection 65 is used to engage the drawer portion. A stop 69 may be configured. In the above embodiment, the electrical function unit is configured by the slider 40 and the pattern 23. However, the electrical function unit may have other various structures. In short, the electrical output is changed by the movement of the moving body. Any structure may be used as long as it is an electrical functional unit. In the above embodiment, the coil portion 52 of the torsion coil spring 50 is wound twice in a half-coil shape, but may be wound by another number of turns.
