  2. Description of the Related Art Conventionally, a rotary electric component that detects a rotation operation amount with respect to a rotary shaft that is rotated is known. In particular, a rotary electric component having a built-in push switch that detects a pressing operation on a rotary shaft is used for various controls of electronic devices and the like. For example, Patent Document 1 discloses a rotary electrical component that is excellent in operability by preventing unevenness in rotational torque.

  FIG. 8 is an exploded perspective view of the rotating electrical component 100 described in Patent Document 1. In FIG. FIG. 9 is a cross-sectional view of the rotating electrical component 100 in the initial state. FIG. 10 is a cross-sectional view when a pressing operation is performed on the rotating electrical component 100. The rotary electric component 100 holds a metal bearing member 101, a shaft member 102 that is rotatably inserted, a slider receiver 104 that holds the slider 103 and rotates together with the shaft member 102, and a substrate 105.

When the connecting member 114 is rotated, the slider receiver 104 is also rotated together with the connecting member 114. When the slider receiver 104 rotates, the slider 103 slides on the conductive pattern of the substrate 105. At this time, a signal corresponding to the contact position of the slider 103 on the conductive pattern is output via the external connection terminal. In an electronic device or the like on which the rotary electrical component is mounted, a rotational operation amount with respect to the shaft member 102 is detected according to the output signal.

  On the other hand, when the pressing operation is performed on the shaft member 102 from the initial state illustrated in FIG. 9, the shaft member 102 is moved to a position where the flange 121 contacts the upper surface of the bearing member 101 as illustrated in FIG. 10. Moving. Along with this, the shaft member 102 pushes the contact portion 151 of the rubber member 115 downward. As a result, the reversing portion 152 of the rubber member 115 is reversed, and the lower surface of the abutting portion 151 pushes down the contact portion 182 of the movable contact 108 and makes contact with the central fixed contact 191. By the contact between the contact portion 182 and the center fixed contact 191, an ON signal of the push switch is output via the external connection terminal. In an electronic device or the like on which the rotary electrical component 100 is mounted, the presence or absence of a pressing operation on the shaft member 102 is detected according to the output signal.

Conductive members 33, 34, and 35 that are divided in the direction are provided. The rotating body 31 is made of a synthetic resin, and a through portion is formed in a portion that accommodates the driving body 15. This through portion rotates the rotating body 31 integrally with the driving body 15 when the driving body 15 rotates about the axis 10a, and moves the driving body 15 and the shaft section 11 when the driving body 15 moves downward. It has a shape that enables it. The slider 32 is obtained by processing a metal leaf spring. The conductive members 33, 34, and 35 are obtained by processing a conductive metal. The slider 32 is configured to be able to detect the rotation of the rotating body 31 by making contact with and separating from the electrode patterns of the conductive members 33, 34, and 35. Part of the conductive members 33, 34, and 35 is exposed to the outside from a first case member 51, which will be described later, and constitutes a terminal portion.

The support member 43 is disposed at a position where it does not contact the fixed contact portion 42 a and the terminal portion 42 b, and the support contact portion 43 a supports the support portion 41 b of the movable contact member 41. The elastic member 45 is made of, for example, silicone rubber formed into a dome shape, and can be elastically deformed in the vertical direction. The leg part located on the outer periphery of the elastic member 45 is disposed so as to contact the support part 41b of the movable contact member 41, and the central part of the elastic member 45 is separated from the movable contact part 41a in the initial state. The elastic member 45 presses the movable contact portion 41a so that the movable contact portion 41a contacts the fixed contact portion 42a when elastically deforming so that the leg portion buckles.

  The case member 50 includes a first case member 51 that holds the conductive members 33, 34, and 35, a second case member 52 that holds the fixed contact member 42 and the support member 43, and the first case member 51 and the second case member. 52 and a cover 53 that holds the bearing member 20 together.

  The first case member 51 is made of an insulating synthetic resin, and is insert-molded integrally with the conductive members 33, 34, and 35 as shown in FIGS. 3 and 4.

  The second case member 52 is made of an insulating synthetic resin, and is insert-molded integrally with the fixed contact member 42 and the support member 43 as shown in FIGS. 3 and 4.

  The cover 53 is obtained by bending a metal plate. 1-4, the cover 53 includes an upper plate portion 53a, a side plate portion 53b formed by bending from the upper plate portion 53a, and a locking portion 53c formed by bending from below the side plate portion 53b. I have. The upper plate portion 53a has an opening through which the cylindrical portion 25 of the bearing member 20 protrudes. The side plate portion 53b is disposed on two opposing surfaces of the flange portion 26 of the bearing member 20, the first case member 51, and the second case member 52 so as to sandwich the side plate portion 53b. The locking portion 53 c locks the lower side of the second case member 52.

  In the rotating electrical component 1 according to the present embodiment, the rotating body 31 to which the movable contact member 41, the elastic member 45, the first case member 51, and the slider 32 are fixed is placed on the second case member 52. . On the other hand, the shaft member 10 is driven to the engaging portion 11a after the shaft portion 11 is inserted into the bearing member 20 to which the spring member 36 is fixed and the retaining ring member 16 is fitted to the shaft portion 11. The body 15 is fixed. In this state, the bearing member 20 is placed on the first case member 51 so that the driving body 15 contacts the elastic member 45. And the cover 53 is arrange | positioned from the state in the state which is not bending the latching | locking part 53c, and finally the latching | locking part 53c is bent and integrated.

  As shown in FIG. 1, the rotary electric component 1 of the present embodiment is provided so that the operation portion 12 of the shaft member 10 can be rotated and pressed. The rotating electrical component 1 can detect the rotating operation and the pressing operation of the shaft member 10 as follows.

  The rotation detecting unit 30 is configured such that the rotating member 31 rotates by rotating the shaft member 10, and the electrode patterns of the conductive members 33, 34, and 35 come in contact with and separate from the three contact portions of the slider 32. , 34 and 35 are switched, and a signal corresponding to the contact position of the contact portion of the slider 32 is output. Thus, the rotation operation can be detected by the change of the output signal. Further, when the rotating body 31 is rotated by the rotation operation of the shaft member 10, the spring member 36 is elastically contacted with the concavo-convex portion formed on the rotating body 31, and an appropriate operation feeling is generated on the operation unit 12. Can do.

  As shown in FIGS. 5 and 6, the push switch 40 is driven by a pressing operation of the shaft member 10 in the direction of the axis 10a. That is, when a pressing operation is performed on the operation unit 12 from the initial state shown in FIG. 5, the elastic member 45 is deformed by the pressing operation as shown in FIG. 6, and the movable contact of the movable contact member 41 is moved. The portion 41 a contacts the fixed contact portion 42 a of the fixed contact member 42. As a result, the terminal part 42 b of the fixed contact member 42 and the terminal part 43 b of the support member 43 are electrically connected via the movable contact member 41. Therefore, the pressing operation of the shaft member 10 can be detected. Further, when released from the pressing operation, as shown in FIG. 5, the elastic member 45 is restored to the initial state, and the movable contact portion 41a is separated from the fixed contact portion 42a. Therefore, it can be detected that the state has returned to the non-pressing operation state.

  Next, the features of the rotary electrical component 1 of the present embodiment will be described in detail.

  The shaft member 10 is provided with a first inclined portion 13 formed so as to connect the shaft portion 11 and the lower end surface 12a of the operation portion 12. On the other hand, the bearing member 20 is provided with a receiving portion 22 formed in a shape capable of coming into contact with the first inclined portion 13 on the inner peripheral surface of the cylindrical portion 25 on the distal end surface 25a side. More specifically, as shown in FIG. 7, the receiving portion 22 includes a second inclined portion 23, and gradually becomes larger than the diameter of the shaft portion 11 from the lower side toward the distal end surface 25 a side, and the shaft portion 11. And a diameter smaller than the maximum diameter of the first inclined portion 13 that connects the lower end surface 12a of the operation portion 12 to each other. As shown in FIGS. 2 and 5, the lower end surface 12 a of the operation portion 12 is opposed to the front end surface 25 a of the bearing member 20 in the initial state.

  In this embodiment, as shown in FIG. 7, the angle θ of the tapered surface of the first inclined portion 13 is 20 degrees with respect to the direction of the axis 10 a of the shaft member 10. As shown in FIG. 7, the receiving portion 22 is provided with a second inclined portion 23 that is inclined in the same direction as the first inclined portion 13. In the present embodiment, the first inclined portion 13 and the second inclined portion 23 of the shaft member 10 are formed at the same angle.

  When the operation part 12 is pressed downward, the push switch 40 is driven and the first inclined part 13 comes into contact with the second inclined part 23 provided in the receiving part 22. Since the 2nd inclination part 23 inclines in the same direction as the 1st inclination part 13 at the same angle, the 1st inclination part 13 contacts smoothly and the 1st inclination part 13 and the 2nd inclination part 23 are surface. Touch slightly. In addition, the taper surface takes into account manufacturing variation so that the first inclined portion 13 on the lower end surface 12 a side has a diameter larger than the maximum inner diameter of the receiving portion 22, and after contacting the second inclined portion 23. Any angle that can be slidably contacted so as to rub slightly may be used. As a result of examining the angle θ of the taper surface, if the angle is 15 degrees or more and 30 degrees or less, the above-described effect is exhibited, and 20 degrees is determined to be optimal.

  Conventionally, unlike the present embodiment, the first inclined portion 13 and the receiving portion 22 with which the first inclined portion 13 abuts are not provided. For this reason, there has been a problem that the surfaces perpendicular to the direction of the axis 10a of the lower end surface 12a of the operation portion 12 and the tip end surface 25a of the cylindrical portion 25 of the bearing member 20 are in direct contact with each other. In particular, when both the shaft member 10 and the bearing member 20 are made of a metal material, a collision sound in which the metals collide with each other becomes prominent.

  In the present embodiment, during the pressing operation of the shaft member 10, the first inclined portion 13 of the shaft member 10 first comes into contact with the receiving portion 22 of the bearing member 20, and the surfaces orthogonal to the direction of the axis 10a at that time point Contact is suppressed. Therefore, the collision sound at the time of the pressing operation can be reduced, and the quality can be improved.

  Furthermore, since the first inclined portion 13 is in smooth contact with the second inclined portion 23 and is in sliding contact with the surface slightly, the contact at the first inclined portion 13 is stabilized. In addition, it is preferable that the inclination angle of the 1st inclination part 13 and the 2nd inclination part 23 is 15 degrees or more and 30 degrees or less. In this case, since the angle is not too large, the first inclined portion 13 can appropriately enter the receiving portion 22 of the bearing member 20 and the receiving portion 22 can be slightly expanded. Even when a large load is applied, the first inclined portion 13 enters the receiving portion 22 of the bearing member 20 and acts to widen the receiving portion 22 slightly.

  According to such a configuration, it is considered that a braking force for buffering the movement of the shaft member 10 is generated. Moreover, it becomes difficult to produce contact | abutting by the surfaces orthogonal to the direction of the axis 10a which had produced the collision sound with the conventional structure. It seems that these actions make it difficult to produce a loud collision sound. The second inclined portion 23 may not be provided, and the shape of the receiving portion 22 may be a curved surface. In this case, although the area which makes sliding contact decreases, since the 1st inclination part 13 contacts smoothly, the collision sound in the case of pressing operation can be made small.

  Further, when a load greater than that driven by the push switch 40 is applied to the shaft member 10, the lower end surface 12 a of the operation portion 12 is moved to the bearing member after the first inclined portion 13 and the receiving portion 22 come into contact with each other. It is preferable that the front end surface 25a is configured to be in contact with the front end surface 25a. Even if an excessive pressing force is applied to the shaft member 10, the lower end surface 12 a of the operation portion 12 abuts on the front end surface 25 a of the bearing member 20, and the receiving portion 22 of the bearing member 20 does not expand too much. It is possible to prevent a problem that 10 does not return to the initial state while biting into the receiving portion 22.

  Even if the shaft member 10 is formed of a metal material, the lower end surface 12a of the operation unit 12 abuts on the front end surface 25a of the bearing member 20 before an overload is applied to the push switch 40, and the push switch 40 is pressed. Since the load is regulated, the push switch 40 can be prevented from being broken.

  When the thickness of the cylindrical portion 25 of the bearing member 20 is thin, there is a concern that if the receiving portion 22 is excessively widened, the lower end surface 12a of the operating portion 12 is connected to the distal end surface 25a of the bearing member 20. If it is configured so that the receiving portion 22 does not spread too much due to contact, it can be made difficult to break.

  Hereinafter, the effect by having set it as this embodiment is demonstrated.

  The rotary electric component 1 of the present embodiment includes a metal bearing member 20 having a cylindrical portion 25 in which a through hole 21 is formed, and a shaft member 10 that is made of a metal material and is rotatably inserted into the through hole 21. And a rotation detecting means 30 for detecting the rotational movement of the shaft member 10 and a push switch 40 driven by a pressing operation of the shaft member 10 in the direction of the axis 10a. The shaft member 10 is inserted into the through hole 21. The shaft portion 11 and the operation portion 12 disposed outside the bearing member 20 and formed in a shape larger than the shaft portion 11, and the lower end surface 12 a of the operation portion 12 in the initial state is the distal end surface 25 a of the bearing member 20. In the rotary electrical component 1 that is spaced apart and facing the shaft member 10, the shaft member 10 is provided with a first inclined portion 13 formed so as to connect the shaft portion 11 and the lower end surface 12 a of the operation portion 12. 1 inclined part 13 is a shaft part The diameter is formed so as to increase from the 1 side toward the operation portion 12 side, and the inner peripheral surface on the distal end surface 25a side of the bearing member 20 is formed in a shape that can contact the first inclined portion 13. When the operation portion 12 is pressed downward, the push switch 40 is driven and the first inclined portion 13 comes into contact with the reception portion 22.

  According to this configuration, during the pressing operation of the shaft member 10, the first inclined portion 13 of the shaft member 10 contacts the receiving portion 22 of the bearing member 20, and contact between surfaces orthogonal to the direction of the axis 10a is suppressed. Therefore, the collision sound at the time of the pressing operation can be reduced, and the quality can be improved.

  In the rotating electrical component 1 of the present embodiment, the receiving portion 22 is provided with a second inclined portion 23 that is inclined in the same direction as the first inclined portion 13, and when the operating portion 12 is pressed downward. The first inclined portion 13 contacts the second inclined portion 23.

  According to this structure, since the 2nd inclination part 23 provided in the receiving part 22 inclines in the same direction as the 1st inclination part 13, the 1st inclination part 13 contacts smoothly, and more collision sound is made. Can be small.

  In the rotating electrical component 1 of the present embodiment, the first inclined portion 13 and the second inclined portion 23 are inclined at the same angle.

  According to this configuration, the first inclined portion 13 and the second inclined portion 23 are in sliding contact with each other slightly, so that the contact is stable and variation in sound generation can be suppressed.

  In the rotating electrical component 1 of the present embodiment, it is preferable that the inclination angles of the first inclined portion 13 and the second inclined portion 23 are 15 degrees or more and 30 degrees or less.

  According to this configuration, since the angle is not too large, the first inclined portion 13 can appropriately enter the receiving portion 22 of the bearing member 20 and the receiving portion 22 can be slightly expanded.

  In addition, the rotary electrical component 1 of the present embodiment is configured such that when a load greater than that driven by the push switch 40 is applied to the shaft member 10, the first inclined portion 13 and the receiving portion 22 come into contact with each other. The lower end surface 12a of the operation unit 12 contacts the front end surface 25a of the bearing member 20.

  According to this configuration, even if an excessive pressing force is applied to the shaft member 10, the lower end surface 12 a of the operation portion 12 abuts on the front end surface 25 a of the bearing member 20, and the receiving portion 22 of the bearing member 20 expands. Therefore, the problem that the shaft member 10 does not return to the initial state while biting into the receiving portion 22 can be prevented. Even if the shaft member 10 is formed of a metal material, the lower end surface 12a of the operation unit 12 abuts on the front end surface 25a of the bearing member 20 before an overload is applied to the push switch 40, and the push switch 40 is pressed. Since the load is regulated, the push switch 40 can be prevented from being broken.
