Description

  The present invention relates to a multi-directional slide type electronic component capable of obtaining an output signal corresponding to a moving position by moving an operating body in multiple directions on a plane.

  Conventionally, among slide-type electronic components, for example, as shown in Patent Document 1, a large-diameter portion (13a) of an operating body (13) and a large-diameter portion (13a) are provided inside a housing (10). An annular coil spring (14) surrounding the actuator and a detecting means such as a slider (17, 18) for detecting the position of the operating body (13) are housed and installed, and the operating body (13) is slid. Then, when the large-diameter portion (13a) presses and extends the portion of the annular coil spring (14) positioned in the sliding direction and removes the sliding operation force, the operating body (by the pulling force of the annular coil spring (14) ( A multi-directional slide type electronic component having a structure in which 13) is automatically returned to the initial position is disclosed.

JP 2005-310669 A

However, the conventional multi-directional slide type electronic component has the following problems.
(1) Since the annular coil spring (14) is attached to the outer periphery of the large-diameter portion (13a), the outer diameter of the housing (10) is increased correspondingly, and downsizing is hindered.

(2) At the time of assembling the multi-directional slide type electronic component, when the annular coil spring (14) is attached to the outer periphery of the large diameter portion (13a), the annular coil spring (14) is directly attached to the large diameter portion (13a). If it is going to do, since an annular coil spring (14) will be easy to remove | deviate from a large diameter part (13a), the assembly operation will become complicated. For this reason, in Patent Document 1, a pin-shaped assembly jig (30) is inserted into the jig insertion hole (10c) of the housing (10), and the annular coil spring (14) is inserted into the assembly jig (30). By assembling the operating body (13), the lower case (12), etc. in order on the upper case (11) while being wound and temporarily held, the assembly jig (30) is then removed from the jig insertion hole (10c). The annular coil spring (14) was attached to the large diameter portion (13a). According to this method, the annular coil spring (14) can be reliably attached to the outer periphery of the large diameter portion (13a). However, this method requires a step of temporarily holding the annular coil spring (14) on the assembly jig (30) and then removing the assembly jig (30). Efficiency cannot be improved.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a multi-directional slide-type electronic component that can be reduced in outer diameter and can be easily assembled.

A multi-directional slide-type electronic component according to the present invention includes a case having an opening, an operating body main body that is installed in the case so as to be movable in a plane direction and has a larger diameter than the opening of the case, and the case An operating body that is exposed to the opening of the operating body, and a detecting unit that changes a detection output according to a position where the operating body moves, and at least one of upper and lower surfaces of the operating body main body. A first spring storage portion formed of a concave portion is provided on the inner peripheral side surface of the first spring receiving portion, and a second spring storage portion formed of a concave portion is formed on the inner surface of the case facing the first spring storage portion of the operating body main body portion. A ring-shaped elastic body in a space formed by opposing the first spring storage portion of the operating body main body and the second spring storage portion of the case. The outer circumference of the ring-shaped elastic body is stored first When the operating body is held in the neutral position by simultaneously elastically contacting the second spring receiving surface, and the operating body is moved from the neutral position with respect to the case, the ring-shaped elastic body is compressed and deformed so that the operating body is moved to the neutral position. An elastic return force is generated.
If comprised in this way, since a ring-shaped elastic body is arrange | positioned inside the outer periphery of an operation body main-body part, size reduction of the outer diameter dimension of a multi-directional slide type electronic component can be achieved.

If comprised in this way, even if it presses and compresses any part of the outer periphery of a ring-shaped elastic body, the uniform elastic restoring force which tries to return to the original shape will arise.

  Also, the method of assembling the multi-directional slide type electronic component according to the present invention accommodates the operating body main body of the operating body in a case having an opening so as to be movable in the surface direction. In the assembling method of the multi-directional slide type electronic component which is assembled by housing the detecting means which exposes the part and accommodates the detecting means which changes the detection output according to the position where the operating body moves in the case, A first spring housing portion formed of a recess is provided on at least one of the upper and lower surfaces, and the inner peripheral side surface is a first spring receiving surface. The inner surface of the case facing the first spring housing portion of the operating body main body is provided with a second spring housing portion formed of a recess, the inner peripheral side surface of which is a second spring receiving surface, and a ring-shaped elastic body Prepare the case When the operating body main body is stored inside, the ring-shaped elastic body is inserted into one of the first spring storage portion and the second spring storage portion while compressing it in advance, and the other is covered with this.

FIG. 6 is a perspective view showing another ring-shaped elastic body 30-2 and a third case 40.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 is a perspective view of a multi-directional slide type electronic component 1 according to an embodiment of the present invention, FIG. 2 is a cross-sectional view taken along line AA of FIG. 1, and FIG. 3 is an exploded perspective view of the multi-directional slide type electronic component 1. 4 is an exploded perspective view of the multi-directional slide-type electronic component 1 as viewed from below. As shown in these drawings, in the multi-directional slide type electronic component 1, the operating body 10, the ring-shaped elastic body 30, and the third case 40 are installed below the second case 60, and the second case 60 is above the second case 60. The second slide moving body 80, the first slide moving body 100, the rotation stopping moving body 120, and the first case 140 are installed. The whole of the first, second, and third cases 140, 60, and 40 constitutes a case. In the following description, “upper” refers to the direction of viewing the operating body 10 from the ring-shaped elastic body 30, and “lower” refers to the opposite direction. In addition, a slide movement direction of the rotation stop moving body 120 and the second slide movement body 80 described below is a first direction E, and a slide movement direction of the first slide movement body 100 is a second direction F. The first and second directions E and F are orthogonal to each other, and one surface is formed by both directions, and the operating body 10 slides in this surface direction as described below.

  The operation body 10 is a molded body of a synthetic resin (for example, a liquid crystal polymer), and is configured by projecting a rod-shaped operation section 21 from the center of the upper surface of the substantially disk-shaped operation body main body 11. On the lower surface of the operating body main body 11, a first spring accommodating portion 13 made of a circular recess is formed. An inner peripheral side surface of the first spring storage portion 13 is a first spring receiving surface 15.

Further, for example, the connection is performed by preparing one spring receiver having projections to be inserted into the inner diameter of the coil spring on both surfaces, and inserting the inner diameter portions of both ends of the linear coil spring into both protrusions of the spring receiver. May be. As will be described below, since the ring-shaped elastic body 30 is only applied with a force in the direction in which it is compressed, a force in a direction in which both ends are always pressed acts on the connecting portions at both ends of the coil spring. For this reason, there is no fear that the connection portion is pulled and the connection is released, and the connection strength may be weak. Accordingly, it is possible to easily form a linear coil spring in a ring shape.

Both protrusions 105 extend in a direction orthogonal to the longitudinal direction of the first slide moving body 100 (second direction F), and the separation distance between the opposing inner walls of both protrusions 105 is described below. The distance between the outer side walls of the rail portions 145-1 and 145-3 of the first case 140 is substantially the same. A slider 110 made of an elastic metal plate is attached near one end of the lower surface of the first slide moving body 100. The slider 110 is configured by projecting two arm-shaped elastic contact portions 113 from a base portion 111 and folding these elastic contact portions 113 by approximately 180 °.

  The rotation stop moving body 120 is made of a rectangular (strip-shaped) metal plate (for example, an iron plate), and both end portions thereof are bent downward in an L shape so that both outer side surfaces serve as sliding portions 121. The distance between the sliding portions 121 is substantially the same as the distance between the inner walls of the rail portions 145-2 and 145-4 facing each other in the first case 140 described below.

  The first case 140 is a molded product of a synthetic resin (for example, a liquid crystal polymer) and has a substantially rectangular flat plate shape, and is configured by providing an opening 141 formed of a circular through hole at the center thereof. The inner diameter of the opening 141 is substantially the same as the inner diameter of the operation portion insertion portion 61 of the second case 60. In the vicinity of each corner on the lower surface of the first case 140, a mounting portion 143 is formed that includes small protrusions that are inserted into the mounted portions 63 of the second case 60 and the mounted portions 47 of the third case 40. ing. Rail portions 145-1 to 145-4 that protrude in a rectangular shape are formed around the opening 141 on the lower surface of the first case 140 so as to surround the opening 141.

  In order to assemble the multi-directional slide type electronic component 1, first, the rotation stop moving body 120, the first slide moving body 100, and the second slide moving body 80 are installed on the lower surface side of the first case 140. At that time, the anti-rotation moving body 120 and the second slide moving body 80 face the same direction, and the first slide moving body 100 faces the direction orthogonal to them. At this time, both sliding portions 121 of the rotation stop moving body 120 are inserted into and engaged with the inner side walls of the opposing rail portions 145-2 and 145-4 of the first case 140, and the first slide moving body 100 is Both projecting portions 105 are inserted and engaged with the outer side walls of the opposing rail portions 145-1 and 145-3 of the first case 140, and both projecting portions 85 of the second slide moving body 80 are inserted into the first case 140. It is inserted and engaged with the outer side wall side of the opposing rail portions 145-2 and 145-4. As a result, the anti-rotation moving body 120 and the second slide moving body 80 slide in the first direction E along the rail portions 145-2 and 145-4, and the first slide moving body 100 is It is configured to slide along the rail portions 145-1 and 145-3 in the second direction F.

  Next, the second case 60 is installed on the lower side of the first case 140 that houses the first slide moving body 100 and the like. At this time, the attachment portions 143 of the first case 140 are attached to the respective attachments of the second case 60. The tip of each attachment part 143 protrudes to the lower surface side of the second case 60.

  Next, the operating body 10 is installed below the second case 60. At that time, the operation portion 21 of the operation body 10 is inserted into the operation portion insertion portion 61 of the second case 60 and the operation portion insertion portion 165 of the output extraction board 160, and the long hole 81 of the second slide moving body 80. And the long hole 101 of the first slide moving body 100 and the long hole 123 of the rotation stopping moving body 120 are inserted into the overlapping portion, and further inserted into the opening 141 of the first case 140. At this time, both inner sides 125 of the rotation stop moving body 120 abut (or approach) both flat portions 23 of the operation unit 21, and both inner sides 103 of the first slide moving body 100 are both arcs of the operation unit 21. Abutting (or approaching) the surface 25, both inner sides 83 of the second slide moving body 80 abut (or approach) both the planar portions 23 of the operation unit 21.

  Next, the ring-shaped elastic body 30 is press-fitted (inserted) into the first spring housing portion 13 on the lower surface of the operation body main body 11 of the operation body 10 while slightly reducing the outer shape. Next, the third case 40 is put on the lower side of the ring-shaped elastic body 30, and the lower half of the ring-shaped elastic body 30 is inserted into the second spring housing portion 43 at that time. At the same time, each attachment portion 143 of the first case 140 protruding to the lower surface side of the second case 60 is inserted into each attachment portion 47 of the third case 40. And the front-end | tip of each attaching part 143 which protruded from the lower surface of the 3rd case 40 is heat-caulked. Thereby, the multi-directional slide type 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. For example, the ring-shaped elastic body 30 is press-fitted into the second spring accommodating portion 43 of the third case 40 in advance, and then the operating body 10 is installed on the third case 40 so that the upper half of the ring-shaped elastic body 30 is moved to the first. You may insert in 1 spring accommodating part 13. FIG.

  As described above, the multi-directional slide-type electronic component 1 is installed in the first, second, and third cases 140, 60, and 40 and in the second and third cases 60 and 40 so as to be movable in the surface direction. The operating body 10 having the operating body main body 11 and detection means (first and second) which are installed in the first and second cases 140 and 60 and change the detection output according to the position where the operating body 10 moves. Slide moving bodies 100, 80, both sliders 110, 90, and both sliding contact patterns 161), and a first spring storage portion 13 formed of a concave portion is provided on the lower surface of the operation body main body 11, and its inner periphery A side surface is a first spring receiving surface 15, and a second spring storage portion 43 made of a recess is provided on the inner surface of the third case 40 facing the first spring storage portion 13 of the operating body main body 11, and the inner peripheral side surface is provided. The second spring receiving surface 46 is used as the first body of the operating body main body 11. Ne is constructed by accommodating the ring-shaped elastic body 30 and the second spring receiving portion 43 of the housing 13 and the third casing 40 in the space formed by opposing.

  FIG. 6 is a schematic plan view showing an engagement state between the ring-shaped elastic body 30 and the first and second spring receiving surfaces 15 and 46 at this time. As shown in the figure, the ring-shaped elastic body 30 tries to maintain a circular shape by its elastic restoring force when no external force is applied, so that the outer periphery of the ring-shaped elastic body 30 has the first and second spring receiving surfaces 15 and 46. At the same time, the first and second spring receiving surfaces 15 and 46 are made to coincide with each other by being elastically contacted (pressed) simultaneously. That is, the operating body 10 is held at the neutral position with respect to the third case 40.

  In the multi-directional slide-type electronic component 1 having the above-described configuration, when the operation body 10 at the neutral position is slid in the second direction F, as shown in FIG. The inner side 103 of the moving body 100 is pressed and the first slide moving body 100 is slid in the second direction F. As a result, the slider 110 attached to the first slide moving body 100 slides on one set of the sliding contact pattern 161 of the output extraction substrate 160, and the output signal thereof changes. When the operation unit 21 moves in the second direction F, the operation unit 21 moves in the long hole 123 of the rotation stopping moving body 120 and the long hole 81 of the second slide moving body 80 in the longitudinal direction. Therefore, the rotation stop moving body 120 and the second slide moving body 80 do not move.

  At this time, as shown in FIG. 7, the first spring accommodating portion 13 of the operating body 10 moves relative to the second spring accommodating portion 43 of the third case 40, whereby the ring-shaped elastic body 30 becomes the second and first springs. The receiving surfaces 46 and 15 are pressed from the left and right to be compressed into a substantially elliptical shape. As a result, an elastic restoring force is applied between the second and first spring receiving surfaces 46 and 15 so that the ring-shaped elastic body 30 returns to its original shape. That is, when the operating body 10 is moved from the neutral position relative to the third case 40, the ring-shaped elastic body 30 is compressed and deformed to generate an elastic return force to the neutral position. Therefore, if the movement of the operating body 10 is stopped and the pressing is released, the operating body 10 automatically returns to the original neutral position and returns to the state shown in FIG.

  On the other hand, when the operation body 10 in the neutral position is slid in the first direction E, the operation unit 21 has the plane part 23 whose inner side 125 is the rotation stop moving body 120 and the inner side 83 of the second slide movement body 80. Are simultaneously pressed and slid in the first direction E. As a result, the slider 90 attached to the second slide moving body 80 slides on the other set of sliding contact patterns 161 of the output extraction board 160, and the output signal thereof changes. When the operation unit 21 moves in the first direction E, the operation unit 21 moves in the long hole 101 of the first slide moving body 100 in the longitudinal direction, so that the first slide moving body 100 is Do not move. Further, when the driving of the operating body 10 is released, the operating body 10 is automatically returned to the original neutral position by the elastic return force of the ring-shaped elastic body 30 as in the case described above.

  Further, if the operating body 10 is moved simultaneously in the first and second directions E and F, the anti-rotation moving body 120, the first slide moving body 100, and the first slide body 100 according to the moving distances in the directions E and F, respectively. It goes without saying that the two slide moving bodies 80 move and output signals corresponding to the movement are obtained from the respective sliding contact patterns 161. Further, when the driving of the operating body 10 is released, the operating body 10 is automatically returned to the original neutral position by the elastic return force of the ring-shaped elastic body 30 as in the case described above.

  On the other hand, when a force in the rotational direction is applied to the operation unit 21, the rotation of the operation unit 21 is prevented by the two flat portions 23 of the operation unit 21 coming into contact with both inner sides 125 of the rotation stopping moving body 120. Accordingly, the rotational force of the operation unit 21 is not applied to the first and second slide moving bodies 100 and 80, and fluctuations in the output signal caused by the rotation of these can be reliably prevented, and an accurate output signal is always obtained. can get.

  According to the multi-directional slide type electronic component 1, the ring-shaped elastic body 30 is arranged on the inner side of the outer periphery of the operating body main body 11, so that the outer diameter dimension of the multi-directional slide type electronic component 1 is reduced. be able to.

  Moreover, the ring-shaped elastic body 30 can be accommodated by being pushed into the first and second spring accommodating portions 13 and 43 formed of concave portions as they are. In other words, it is not necessary to use a special jig for storage, the ring-shaped elastic body 30 can be easily stored between the operation main body 11 and the third case 40, and the assembly work of the multi-directional slide type electronic component 1 is possible. Can be easily performed.

  In the multi-directional slide-type electronic component 1, the outer periphery of the ring-shaped elastic body 30 is elastically contacted with the first and second spring receiving surfaces 15 and 46 at the same time. Can be held in a neutral position. Further, since the first and second spring accommodating portions 13 and 43 are circular concave portions having the same inner diameter, the same elastic force works even when the operation body 10 is moved in any surface direction, and a good operation feeling can be obtained. In addition, since the ring-shaped elastic body 30 is formed by winding a coil spring in a ring shape, even if any part of the outer periphery of the ring-shaped elastic body 30 is pressed and deformed by compression, uniform elasticity that tends to return to the original shape is obtained. Restoring power is obtained.

  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, as shown in FIG. 8, a ring-shaped elastic body 30-2 configured by winding a band-shaped metal plate having elasticity into a ring shape may be used as the ring-shaped elastic body. The ring-shaped elastic body 30-2 is configured by winding a band-shaped metal plate in a ring shape a plurality of times, but may be configured by winding it one or more times. The lower half of the outer circumference of the ring-shaped elastic body 30-2 is in elastic contact with the second spring receiving surface 46 of the third case 40, and at the same time the operating body 10 that covers the upper part of the third case 40. The first spring receiving surface 15 also elastically contacts the upper half of the entire circumference. Even in the case of this ring-shaped elastic body 30-2, even if any part of the outer periphery is pressed and compressed and deformed, a uniform elastic restoring force for returning to the original shape can be obtained. Still further, the ring-shaped elastic body may be composed of a rubber material formed in a ring shape or other various materials and structures.

  In the multi-directional slide type electronic component 1, the first spring accommodating portion 13 is provided on the lower surface of the operating body main body 11. Alternatively, the first spring accommodating portion may be provided on the upper surface of the operating body main body 11. good. In this case, the second spring accommodating portion is provided on the lower surface of the second case 60 (that is, the inner surface of the case facing the first spring accommodating portion), and the ring-shaped elastic body 30 is located between the operating body main body 11 and the second case 60. (In a space formed by facing the first spring storage portion and the second spring storage portion).

  In the multi-directional slide type electronic component 1, the first and second slide moving bodies 100 and 80, the sliders 110 and 90, and the sliding contact pattern 161 are used as detection means. Any structure may be used as long as the detection means changes the detection output in accordance with the position. Needless to say, the shape and structure of the operating body 10 and cases 140, 60, and 40 can be variously modified. Further, the output extraction substrate 160 may be formed of a hard substrate, and in that case, the output extraction substrate 160 may be attached to the second case 60 without being insert-molded into the second case 60. Further, the output extraction substrate 160 may be omitted by forming the sliding contact pattern 161 on the surface of the second case 60 itself.
