Description

Rotating electrical parts

The present invention relates to a rotary electric component, and more particularly, to a rotary electric component suitable for a rotary encoder that detects a rotation angle, a rotation direction, and the like of a rotating body according to a rotating operation on the rotating body.

Conventionally, a contact body having a rotating body that is rotatably held in a housing, and a movable contact body that is switched between a conductive state and a non-conductive state between terminals according to the rotational position of the rotating body; There is proposed a rotary electrical component that switches between a conductive state and a non-conductive state between terminals in accordance with a rotating operation on a rotating body (see, for example, Patent Document 1).

JP 2009-16247 A

However, in the rotary electrical component described above, the conductive state between the terminals cannot be switched to the non-conductive state unless the rotating body is rotated. For this reason, for example, when this rotary electric component is applied to a power switch of a washing machine or the like, a situation in which a current such as a standby current continues to be supplied even after washing is completed may occur.

The present invention has been made in view of such a situation, and an object of the present invention is to provide a rotating electrical component that can switch a conduction state between terminals to a non-conduction state without requiring rotation in a rotating body. And

The rotating electrical component according to the present invention includes a casing in which the first terminal is exposed, a rotating body rotatably held in the casing, and the first terminal in contact with and separating from the rotating operation of the rotating body. A second terminal having a movable contact body capable of rotating; and a rotation detecting means for detecting rotation of the rotating body, wherein the conductive state and the non-conductive state are switched between the first terminal and the second terminal. In the rotary electrical component, the movable contact body is moved between the rotary body and the movable contact body in a direction intersecting with a rotation axis direction of the rotary body as the rotary body rotates, and the movable contact body is moved to the first position. A moving member that contacts the terminal is provided, and the contact between the movable contact body and the first terminal is released to return the first terminal and the second terminal that are in a conductive state to a non-conductive state. A return mechanism, wherein the return mechanism includes a solenoid and the solenoid. Wherein the driven by id and a drive member for returning the moving member.

According to this rotary electrical component, the first terminal and the second terminal that are in the conductive state by releasing the contact between the movable contact body and the first terminal by the return mechanism including the drive body that returns the solenoid and the moving member. Can be returned to the non-conducting state, so that the conduction state between the first terminal and the second terminal is switched to the non-conducting state without requiring the rotation of the rotating body by controlling energization to the solenoid. be able to. As a result, for example, when the rotary electrical component is applied to a power switch of a washing machine or the like, it is possible to avoid a situation where a standby current is continuously supplied, and to meet a demand for energy saving. In addition, since the moving member is disposed between the rotating body and the movable contact body, it is possible to prevent the rotation of the rotating body from being directly transmitted to the movable contact body. Contact stability can be improved.

For example, in the rotating electrical component, the moving member includes a base portion and a pressing portion that protrudes toward the movable contact body from the base portion, and the movable contact body protrudes toward the moving member side. When the first terminal and the second terminal are in a conductive state, the pressing portion is in contact with the protruding portion and presses the movable contact body toward the first terminal. In this case, when the first terminal and the second terminal are in a conductive state, the movable contact body comes into contact with the protruding portion by the pressing portion provided on the moving member and is pressed to the first terminal side. Thus, it is possible to stably switch the conductive state between the first terminal and the second terminal without having a complicated configuration.

In particular, in the rotating electrical component, the protrusion is pressed toward the first terminal by the pressing portion as the moving member moves in one direction, and the one end of the pressing portion is positioned at the end in the one direction. Is preferably provided with a convex holding portion for holding the protruding portion of the movable contact body. In this case, since the protrusion of the movable contact body can be stably held by the holding portion provided in the pressing portion, the protrusion moves from the pressing portion due to vibration or the like, and the first terminal and the second terminal are electrically connected. It is possible to suppress a problem that the state is switched to the non-conduction state.

In the rotating electrical component, the rotating body is provided with a plurality of first cam portions including a plurality of concave portions and convex portions in the circumferential direction. The convex portion of one cam portion engages with a first engaging portion provided on the moving member to move the moving member in a direction crossing the rotational axis direction of the rotating body, and the movable contact body Is preferably brought into contact with the first terminal. In this case, a plurality of convex portions provided in the circumferential direction of the rotating body engage with the first engaging portion provided on the moving member, and the moving member is moved in a direction intersecting the rotation axis direction of the rotating body. Therefore, since the moving member can be moved at a plurality of positions as the rotating body rotates, even when the first terminal and the second terminal are switched to the non-conducting state at a position other than the initial position by the return mechanism, a short period of time can be obtained. It becomes possible to return to the conductive state by (rotating operation with few rotating bodies).

Further, in the rotary electric component, a holding member that holds the moving member so as to be movable is provided to face the moving member, and the holding member has the first cam portion of the rotating body. It is preferable that an opening for exposing is formed. In this case, since the moving member is movably held by the holding member, the moving member can be smoothly moved in a direction intersecting the axial direction of the rotating body.

Further, in the rotating electrical component, the rotating body accommodates an engaging body elastically biased toward the outer side in the radial direction of the rotating body, and the holding member is engaged with the engaging body. When a plurality of second cam portions including a plurality of recessed portions and convex portions to be removed are provided, and the engaging body is engaged with the recessed portions of the second cam portion, the first engaging portion is The first cam portion preferably faces the recess. In this case, when the engaging body engages with the concave portion of the second cam portion and the rotating body is in the stable position, the first engaging portion of the moving member faces the concave portion of the first cam portion. Therefore, when the moving member is returned by the driving body by driving the solenoid, the first engaging portion comes into contact with a part of the rotating body (the convex portion of the first cam portion) and the movement of the moving member is hindered. Can be prevented. For this reason, the moving member can be reliably returned by the return mechanism, and the first terminal and the second terminal can be reliably switched to the non-conductive state.

Furthermore, in the rotary electric component, the moving member is provided with a second engagement portion at a position facing the first engagement portion with the rotation axis of the rotation body, and the rotation body. It is preferable that a third cam portion that engages with the second engagement portion and returns the moving member as the rotating body rotates is provided. In this case, since the third cam portion engages with the second engagement portion provided on the moving member and returns the moving member as the rotating body rotates, the initial position of the rotating body by the operator is determined. It is possible to reliably switch the first terminal and the second terminal to the non-conducting state in accordance with the rotation operation.

Furthermore, in the rotating electrical component, the first terminal and the second terminal are provided in pairs, and the movable contact body provided in the pair of second terminals is a rotation axis of the rotating body. The moving member includes a pair of pressing portions corresponding to the movable contact bodies of the pair of second terminals, and a part located between the pair of pressing portions. Is preferably pressed by the driving body. In this case, the moving member can be returned smoothly and stably because the pressing force from the driving body is received at a part located between the pair of pressing portions that press the pair of movable contact bodies. It becomes possible to switch a 1st terminal and a 2nd terminal to a non-conduction state.

Furthermore, in the rotating electrical component, the solenoid has a plunger that can reciprocate in the axial direction of the rotating body, and the driving body is engaged with the shaft portion, a pressing portion that presses the moving member, and the plunger. It is preferable that the engaging portion has a mating portion, and the shaft portion is rotatably held by the housing. In this case, the shaft portion of the driving body is rotatably held by the housing and is engaged with the plunger by the engaging portion, so that the pressing portion of the driving body can be smoothly driven according to the driving of the solenoid. The moving member can be reliably returned to the initial position.

According to the present invention, it is possible to provide a rotating electrical component that can switch a conduction state between terminals to a non-conduction state without requiring rotation in the rotating body.

Note that the rib 615 does not come into contact with the engagement piece 906 because the rib 615 moves from a position corresponding to the engagement piece 906 to a different position in accordance with a rotation operation on the rotating body 6. Further, the contact portion 904 of the slider 9 has a contact surface 904 a disposed in the vicinity of the rear surface of the pressing portion 1402 of the lever 14. In addition, the rotating body 6 on which the rotation operation has been performed is in a state of being disposed at a stable position by the engagement between the steel ball 1201 accommodated in the recess 601 a and the click cam 1008 (recess) of the holder 10.

As described above, in the rotating electrical component 1 according to the present embodiment, the slider 9 is moved in the direction intersecting the rotation axis direction of the rotating body 6 (in this embodiment, the rotating axis line in accordance with the rotating operation on the rotating body 6). The first terminal 13 and the second terminal 11 can be switched to a conductive state by sliding and moving in a direction orthogonal to the direction. In this case, the slider 9 is disposed between the rotating body 6 and the movable contact body 1102. For this reason, the situation in which the rotation of the rotating body 6 is directly transmitted to the movable contact body 1102 can be prevented, so that the contact stability of the movable contact body 1102 with respect to the first terminal 13 can be improved. In particular, since the slider 9 is slidably held by the holder 10, the slider 9 smoothly moves in the front-rear direction of the rotary electrical component 1 (direction intersecting the axial direction of the rotating body 6). It becomes possible.

Furthermore, in the rotary electrical component 1 according to the present embodiment, the slider 9 includes a base 901 and a pressing portion 903 provided so as to protrude from the base 901 to the movable contact body 1102 side. The body 1102 has a projecting portion 1102d projecting toward the slider 9, and when the first terminal 13 and the second terminal 11 are in a conductive state, the pressing portion 903 contacts the projecting portion 1102d and the movable contact body 1102d. Is pressed to the first terminal 13 side. Therefore, when the first terminal 13 and the second terminal 11 are in a conductive state, the movable contact body 1102 comes into contact with the protruding portion 1102d at the pressing portion 903 and is pressed toward the first terminal 13 side. Therefore, it is possible to stably switch the conductive state between the first terminal 13 and the second terminal 11 without having a complicated configuration.

In particular, in the rotating electrical component 1 according to the present embodiment, a holding portion 903a that holds the protruding portion 1102d of the movable contact body 1102 is provided on the upper end of the pressing portion 903 of the slider 9 and on the front end. Is provided. When the protruding portion 1102d gets over the holding portion 903a, the slider 9 is configured to slightly move forward by the elastic return force of the movable contact body 1102, so that the movable contact body 1102 pressed by the pressing portion 903 is used. Since the protruding portion 1102d can be stably held by the holding portion 903a, the protruding portion 1102d moves from the pressing portion 903 due to vibration or the like so that the conductive state between the first terminal 13 and the second terminal 11 is switched to the non-conductive state. It becomes possible to suppress various problems.

FIG. 18 is a perspective view showing a state immediately before the manual-off operation of the rotating electrical component 1 according to the present embodiment. In FIG. 18, a part of the front side of the movable contact body 1102 is omitted for convenience of explanation. When the rotating body 6 is rotated so as to return to the initial state from the power-on state shown in FIG. 16 (that is, when the rotating body 6 is rotated to a position where the rib 615 faces the engagement piece 906 of the slider 9), FIG. As shown in FIG. 18, since the engaging piece 906 is disposed on the rotational movement path of the rib 615, the rib 615 contacts the engaging piece 906. Thereby, as a result of the engagement piece 906 being pushed backward by the rotating body 6, the entire slider 9 slides backward to the position shown in FIGS. 14 and 15. Since the pressing of the protruding portion 1102 d by the pressing portion 903 is released, the movable contact body 1102 moves downward, and the contact portion 1102 c provided on the tongue piece portion 1102 b is separated from the contact portion 1303 of the first terminal 13. (Power off by manual off operation).

As described above, in the rotary electrical component 1 according to the present embodiment, the engagement piece 906 is provided at a position facing the slider 9 across the rotation axis of the engagement piece 909 and the rotation body 6, while the rotation body 6 is provided with the rotation piece 6. A rib 615 is provided that engages with the engaging piece 906 as the rotating body 6 rotates to return the slider 9 to the initial position. Accordingly, the rib 615 can be engaged with the engagement piece 906 and the slider 9 can be returned to the initial position as the rotator 6 rotates, so that the operator can rotate the rotator 6 to the initial position. The first terminal 13 and the second terminal 11 can be reliably switched to the non-conductive state.

Next, the operation during auto-off and manual-on operation after auto-off will be described. As described above, the rotating electrical component 1 according to the present embodiment has an auto-off function for switching from the power-on state to the power-off state by driving the solenoid 15 under a certain condition. For example, the solenoid 15 is driven according to a drive instruction signal output from a control unit such as a device (for example, a washing machine) on which the rotary electrical component 1 itself is mounted. This drive instruction signal is output, for example, when it is detected that there is no operation for a certain period of time from the operator, or when the completion of the designated operation is detected.

FIG. 19 is a diagram illustrating an example of a circuit diagram related to the auto-off function of the rotary electrical component 1 according to the present embodiment. In the circuit diagram shown in FIG. 19, members that are the same as those used in the above description are given the same reference numerals, and descriptions thereof are omitted. 19A shows a circuit diagram in the power-on state, and FIG. 19B shows a circuit diagram in the power-off state switched from the power-on state by the auto-off function.

In the circuit shown in FIG. 19, a pair of

resistance elements

18A and 18B are connected in series to a connection pin 16 connected to a component mounting board. The gate of the triac 17 is connected to the connection point between the resistive element 18A and the resistive element 18B. A solenoid 15 (coil 1501) is connected to one electrode of the triac 17. One second terminal 11 is connected to the other end of the solenoid 15 (coil 1501). Further, the other second terminal 11 and the other electrode of the triac 17 are connected to one end of the resistor element 18B that is not connected to the resistor element 18A. A pair of first terminals 13 is connected to these second terminals 11 via a power switch composed of a movable contact body 1102. An AC power supply voltage (for example, 200 V) is applied (powered) between the pair of second terminals 11.

In the power-on state, the triac 17 is in the off state, and the first terminal 13 and the second terminal 11 are electrically connected by the movable contact body 1102 as shown in FIG. 19A. On the other hand, when a drive instruction signal (predetermined voltage) is input to the triac 17 through the connection pin 16 from the control unit of the device on which the rotary electrical component 1 is mounted under a certain condition, the triac 17 is switched on. A drive current flows through the triac 17 to the solenoid 15 (coil 1501). When the solenoid 15 is driven by this drive current, the conduction state between the first terminal 13 and the second terminal 11 is switched to the non-conduction state by the movable contact body 1102, as shown in FIG. 19B. As a result, power supply to the first terminal 13 via the second terminal 11 is cut off.

20 and 21 are a perspective view and a side view, respectively, during the auto-off operation of the rotating electrical component 1 according to the present embodiment. When a drive instruction signal is input through the connection pin 16 under a certain condition from the power-on state, the solenoid 15 is driven. As a result, the solenoid 15 pulls up the plunger 1503 as the movable iron core against the urging force of the coil spring 1504. An engaging portion 1403 of the lever 14 is engaged with an engaging portion 1503 d provided at the tip of the plunger 1503. For this reason, when the engaging portion 1403 is pulled up with the upward movement of the plunger 1503, the lever 14 rotates with the shaft center of the shaft portion 1401 as a rotation fulcrum.

When the pressing portion 1402 moves rearward as the lever 14 rotates, the pressing portion 1402 contacts the contact surface 904 a provided on the contact portion 904 of the slider 9 and presses the contact portion 904. . As a result, as a result of the contact portion 904 being pushed backward by the lever 14, the entire slider 9 slides backward as shown in FIGS. 20 and 21. As the slider 9 slides, the pressing portion 903 moves from the lower side of the protruding portion 1102d of the movable contact body 1102 to the rear side. As a result, the entire movable contact body 1102 moves downward due to the elastic restoring force, and the contact portion 1102 c provided on the tongue piece 1102 b is separated from the contact portion 1303 of the first terminal 13. Thereby, the 1st terminal 13 and the 2nd terminal 11 are switched to a non-conduction state (power-off state by auto-off operation).

As the slider 9 slides, the engagement piece 906 moves to the rear side and is in a state of being retracted from the rotational movement region of the rib 615. Further, as described above, in the state where the rotating body 6 is disposed at the stable position, the concave portion 613b of the cam portion 613 is disposed at a position facing the engagement piece 909 of the slider 9, so that the slider 9 slides. The engagement piece 909 is accommodated in the recessed part 613b which comprises the cam part 613 provided in the disk shape part 601 of the rotary body 6 by movement. For this reason, when the slider 15 is returned by the lever 14 by driving the solenoid 15, it is possible to prevent the engagement piece 909 from coming into contact with a part of the rotating body 6 (the convex portion 613 a) and obstructing the movement of the slider 9. Therefore, the slider 9 can be reliably returned by the return mechanism, and the first terminal 13 and the second terminal 11 can be reliably switched to the non-conductive state.

As described above, in the rotating electrical component 1 according to the present embodiment, the contact between the movable contact body 1102 and the first terminal 13 is released by the return mechanism including the solenoid 15 and the lever 14 and is in the conductive state. The first terminal 13 and the second terminal 11 can be returned to the non-conductive state. Thereby, by conducting energization control to the solenoid 15, the conduction state between the first terminal 13 and the second terminal 11 can be switched to the non-conduction state without requiring the rotation of the rotating body 6. . As a result, for example, when the rotary electrical component 1 is applied to a power switch of a washing machine or the like, it is possible to avoid a situation where a standby current is continuously supplied, and it is possible to meet a demand for energy saving.

In particular, in the rotary electrical component 1 according to the present embodiment, a pair of the first terminal 13 and the second terminal 11 are provided, and the movable contact body 1102 provided on the pair of second terminals 11 is rotated. They are arranged side by side in the left-right direction across the rotation axis of the body 6. On the other hand, the slider 9 includes a pair of pressing portions 903 corresponding to the movable contact body 1102 of the pair of second terminals 11, and the contact portion 904 positioned between the pair of pressing portions 903 is pressed by the lever 14. Take the configuration. Therefore, the slider 9 receives the pressing force from the lever 14 at the contact portion 904 (more specifically, the contact surface 904a) positioned between the pair of pressing portions 903, so that the slider 9 is smoothly moved. The first terminal 13 and the second terminal 11 can be stably switched to the non-conductive state.

In the rotary electrical component 1 according to the present embodiment, the solenoid 15 has a plunger 1503 that can reciprocate in the vertical direction, while the lever 14 presses the shaft portion 1401, the pressing portion 1402 that presses the slider 9, and the plunger. Since it has an engaging part 1403 that engages with 1503 and the shaft part 1401 is rotatably held by the upper case 3, the pressing part 1402 of the lever 14 can be moved smoothly according to the driving of the solenoid 15. The slider 9 can be reliably returned to the initial position.

22 and 23 are a perspective view and a side view, respectively, after the auto-off operation of the rotating electrical component 1 according to the present embodiment. When the drive instruction signal output via the connection pin 16 is stopped, the solenoid 15 returns to the initial state. The plunger 1503 of the solenoid 15 moves downward according to the urging force of the coil spring 1504. As the plunger 1503 moves, the lever 14 returns to the initial position shown in FIGS. In this case, the slider 9 is in a state where the pressing portion 903 is locked by the protruding portion 1102d of the movable contact body 1102, and does not move forward.

FIG. 24 is a perspective view at the time of a manual on operation after an auto-off operation of the rotary electric component according to the present embodiment. When the rotating body 6 is rotated from the power-off state shown in FIGS. 22 and 23, the protrusion 613 a (more specifically, the protrusion) is engaged with the engagement piece 909 accommodated in the recess 613 b of the cam portion 613. The wall surface portion defining 613a abuts. Thereby, as a result of the engaging piece 909 being pushed forward by the rotating body 6, the entire slider 9 slides forward as shown in FIG.

As the slider 9 slides, the pressing portion 903 presses the protruding portion 1102d of the movable contact body 1102 upward. Accordingly, when the entire movable contact body 1102 is lifted and the projecting portion 1102d is disposed on the pressing portion 903, the contact portion 1102c provided on the tongue piece portion 1102b contacts the contact portion 1303 of the first terminal 13. Thereby, the 1st terminal 13 and the 2nd terminal 11 are switched to a conduction state. That is, in the rotating electrical component 1 according to the present embodiment, after performing the auto-off function, the rotating body 6 can be rotated to return to the power-on state.

As described above, in the rotating electrical component 1 according to the present embodiment, the rotating body 6 is provided with the first cam portion 613 including the plurality of recessed portions 613b and the protruding portions 613a. Then, the convex portion 613a of the first cam portion 613 engages with the engagement piece 909 of the slider 9 to move the slider 9, and the movable contact body 1102 (contact portion 1102c) is moved to the first terminal 13 (contact portion 1303). Make contact. Thereby, since the slider 9 can be moved at a plurality of positions as the rotating body 6 rotates, even when the first terminal 13 and the second terminal 11 are switched to the non-conductive state at a position other than the initial position by the return mechanism. It is possible to return to the conductive state for a short period of time, that is, with a small rotation operation of the rotating body 6.

In addition, various modifications can be made without departing from the scope of the object of the present invention.

For example, in the above-described embodiment, the case where the protruding portion 1102d is configured by a part of the movable contact body 1102 is described. However, the configuration of the protruding portion 1102d is not limited to this, and can be changed as appropriate. For example, a projection made of synthetic resin or the like may be fixed to the movable contact body 1102 so as to have the same function as the protruding portion 1102d.

Further, in the above embodiment, the case where the slider 9 is provided with the flat plate-shaped base portion 901 and the pressing portion 903 protruding upward from the base portion 901 has been described. However, the configuration of the slider 9 is not limited to this, and can be changed as appropriate. For example, the entire slider 9 may be provided with a thickness corresponding to the pressing portion 903 according to the above embodiment, while a recess may be formed in a portion corresponding to the base portion 901 according to the above embodiment.

In the above embodiment, the case where the slider 9 moves in the direction orthogonal to the rotational axis direction of the rotating body 6 as the rotating body 6 rotates is described.

For example, the slider 9 may move in a direction that intersects the rotation axis direction of the rotating body 6 at an angle of 80 °.

In the above embodiment, the case where the steel ball 1201 is used as the engaging body that engages with and disengages from the click cam 1008 that is the second cam portion is described. However, the engagement body is not limited to the steel ball and can be changed as appropriate. For example, a synthetic resin sphere may be used as the engaging body. Moreover, it is not restricted to a spherical body, For example, it is also possible to use the pin-shaped engagement body by which the front end was formed in the curved surface.
